Our fascination with numbers begins when we are children and continues throughout our lives. We start counting our fingers and toes and end up balancing checkbooks and calculating risk. So powerful is the appeal of numbers that many people ascribe to them a mystical significance. Other numbers go beyond the supernatural, working to explain our universe and how it behaves. In Cosmic Numbers , mathematics professor James D. Stein traces the discovery, evolution, and interrelationships of the numbers that define our world. Everyone knows about the speed of light and absolute zero, but numbers lik

3. Generalized Bernoulli-Hurwitz numbers and the universal Bernoulli numbers

The three fundamental properties of the Bernoulli numbers, namely, the von Staudt-Clausen theorem, von Staudt's second theorem, and Kummer's original congruence, are generalized to new numbers that we call generalized Bernoulli-Hurwitz numbers. These are coefficients in the power series expansion of a higher-genus algebraic function with respect to a suitable variable. Our generalization differs strongly from previous works. Indeed, the order of the power of the modulus prime in our Kummer-type congruences is exactly the same as in the trigonometric function case (namely, Kummer's own congruence for the original Bernoulli numbers), and as in the elliptic function case (namely, H. Lang's extension for the Hurwitz numbers). However, in other past results on higher-genus algebraic functions, the modulus was at most half of its value in these classical cases. This contrast is clarified by investigating the analogue of the three properties above for the universal Bernoulli numbers. Bibliography: 34 titles.

6. The universal numbers. From Biology to Physics.

Science.gov (United States)

Marchal, Bruno

2015-12-01

I will explain how the mathematicians have discovered the universal numbers, or abstract computer, and I will explain some abstract biology, mainly self-reproduction and embryogenesis. Then I will explain how and why, and in which sense, some of those numbers can dream and why their dreams can glue together and must, when we assume computationalism in cognitive science, generate a phenomenological physics, as part of a larger phenomenological theology (in the sense of the greek theologians). The title should have been "From Biology to Physics, through the Phenomenological Theology of the Universal Numbers", if that was not too long for a title. The theology will consist mainly, like in some (neo)platonist greek-indian-chinese tradition, in the truth about numbers' relative relations, with each others, and with themselves. The main difference between Aristotle and Plato is that Aristotle (especially in its common and modern christian interpretation) makes reality WYSIWYG (What you see is what you get: reality is what we observe, measure, i.e. the natural material physical science) where for Plato and the (rational) mystics, what we see might be only the shadow or the border of something else, which might be non physical (mathematical, arithmetical, theological, …). Since Gödel, we know that Truth, even just the Arithmetical Truth, is vastly bigger than what the machine can rationally justify. Yet, with Church's thesis, and the mechanizability of the diagonalizations involved, machines can apprehend this and can justify their limitations, and get some sense of what might be true beyond what they can prove or justify rationally. Indeed, the incompleteness phenomenon introduces a gap between what is provable by some machine and what is true about that machine, and, as Gödel saw already in 1931, the existence of that gap is accessible to the machine itself, once it is has enough provability abilities. Incompleteness separates truth and provable, and machines can

10. Universal multifractality in multiparticle production

International Nuclear Information System (INIS)

Florkowski, W.; Hwa, R.C.

1991-01-01

The G moments for the multifractal analysis of multiparticle production are investigated in a model-independent way. By successive bin splitting and assuming the existence of a multiplicity splitting function that depends on multiplicity, but applicable at all steps of the splittings, we study the ergodicity of horizontal and vertical averaging, and derive a universality relation for the G moments. It relates the G moments for different initial multiplicities to a common scaling function Γ q (ξ). The experimental verification of this scaling property would, on the one hand, signify self-similarity in the data, and, on the other, provide a convenient function for comparison not only among different experiments, but also between theory and experiment

Lattice proposals for a nonperturbative formulation of the Standard Model easily lead to a global U(1) symmetry corresponding to exactly conserved fermion number. The absence of an anomaly in the fermion current would then appear to inhibit anomalous processes, such as electroweak baryogenesis in the early universe. One way to circumvent this problem is to formulate the theory such that this U(1) symmetry is explicitly broken. However we argue that in the framework of spectral flow, fermion creation and annihilation still in fact occurs, despite the exact fermion number conservation. The crucial observation is that fermions are excitations relative to the vacuum, at the surface of the Dirac sea. The exact global U(1) symmetry prohibits a state from changing its fermion number during time evolution, however nothing prevents the fermionic ground state from doing so. We illustrate our reasoning with a model in two dimensions which has axial-vector couplings, first using a sharp momentum cutoff, then using the lattice regulator with staggered fermions. The difference in fermion number between the time evolved state and the ground state is indeed in agreement with the anomaly. Both the sharp momentum cutoff and the lattice regulator break gauge invariance. In the case of the lattice model a mass counterterm for the gauge field is sufficient to restore gauge invariance in the perturbative regime. A study of the vacuum energy shows however that the perturbative counterterm is insufficient in a nonperturbative setting and that further quartic counterterms are needed. For reference we also study a closely related model with vector couplings, the Schwinger model, and we examine the emergence of the θ-vacuum structure of both theories. ((orig.))

The analysis of the scientific production of a university is a very complex process and it usually refers to the number of articles published in scientific journals. For most analyses, only a small number of journals is taken into consideration. Usually, there are considered the journals indexed in databases like Science Citation Index (Thompson ISI). However, we consider that for a more complex image of the scientific production of a university, we need to take into consideration several asp...

15. Is the number of photons conserved in an expanding universe

International Nuclear Information System (INIS)

Novello, M.; Oliveira, L.A.R. de; Salim, J.M.

1988-01-01

A Friedman - like scenario in which - due to gravitational interaction - the total number of photons existing in the Universe changes as the Universe expands, is described. The photon number distribution function, in thermal equilibrium, exhibits an explicit dependence on a non-vanishing chemical potential term. This non-null value for the chemical potential of the photon is due to the presence of tidal effects, arising from the direct coupling of the photons - which, in a gravitational field, should not be treated as idealized point-like objects - to the curvature of space-time. As a result, the ratio nγ/n B between the numbers of photons and baryons in the Universe is shown to be not a constat, but rather a function of cosmic time, vanishing when the singularity of the standard FRW model is reached. In consequence, some of the supposed 'fundamental problems' of standard Cosmology (e.g., the explanation of the constancy of the ration nγ/n B and thus of the origin fo the total ammount of entropy observed today) are but apparent ones in the present scenario, and may be ipso facto solved.

16. Universal dependence of the total number albedo of photons on the mean number of photon scatterings

Directory of Open Access Journals (Sweden)

2011-01-01

Full Text Available This paper presents the results of research on photon reflection from plane targets based on Monte Carlo simulations performed by the MCNP code. Five materials (water, concrete, aluminum, iron, and copper are examined in the area of initial photon energies of up to 200 keV. The values of the total number albedo for photons dependent on the initial photon energy or the mean number of photon scatterings are calculated and graphically presented. We have shown that the values of the total number albedo for different target materials, expressed as a function of the mean number of photon scatterings, are in good agreement with each other and can be approximated by simple, universal analytic functions obtained by the least squares method. The accuracy of these analytic appoximations is confirmed by their comparison with the results of PENELOPE and FOTELP Monte Carlo codes.

These are a set of values, but they have a very specific meaning within the context of neoliberal capitalism. They encapsulate certain free market economic values...... that universities are encouraged to cultivate. In this way we can think about universities as being commodified—their core mission has become focused on creating greater economic value for the individual, for corporations, and for the society.

2. Measuring the productivity of university research reactors

International Nuclear Information System (INIS)

Voth, M.H.

1989-01-01

University Research Reactors (URRs) on 33 campuses in the United States provide valuable contributions to academic instruction and research programs. In most cases, there are no alternative diagnostic techniques to supplant the need for a reactor and associated facilities. Since URRs constitute a major financial commitment, it is important that they be operated in a productive manner. Productivity may be defined as the sum of new knowledge generated, existing knowledge transferred to others, and analytical services provided to assist in the generation of new knowledge; another definition of productivity is this sum expressed as a function of the cost incurred. In either case, a consistent measurement is difficult and more qualitative than quantitative. A uniform reporting system has been proposed that defines simplified categories through which meaningful comparisons can be performed

A novel photometry-based estimation of the total number of stars in the Universe is presented. The estimation method is based on the energy conservation law and actual measurements of the extragalactic background light levels. By assuming that every radiated photon is kept within the Universe volume, i.e., by approximating the Universe as an integrating cavity without losses, the total number of stars in the Universe of about 6×1022 has been obtained.

A large lepton number asymmetry of O(0.1−1) at present Universe might not only be allowed but also necessary for consistency among cosmological data. We show that, if a sizeable lepton number asymmetry were produced before the electroweak phase transition, the requirement for not producing too much baryon number asymmetry through sphalerons processes, forces the high scale lepton number asymmetry to be larger than about 03. Therefore a mild entropy release causing O(10-100) suppression of pre-existing particle density should take place, when the background temperature of the Universe is around T = O(10{sup −2}-10{sup 2}) GeV for a large but experimentally consistent asymmetry to be present today. We also show that such a mild entropy production can be obtained by the late-time decays of the saxion, constraining the parameters of the Peccei-Quinn sector such as the mass and the vacuum expectation value of the saxion field to be m {sub φ} ∼> O(10) TeV and φ{sub 0} ∼> O(10{sup 14}) GeV, respectively.

Full Text Available This research addresses the issue of collections in university libraries regarding the building and development of collections. The main objective is to analyze the characteristics of scientific production related to such topic by developing a documental, exploratory, descriptive and both qualitative and quantitative research. The analyzed corpus consists of several international magazines which supply papers with the topic aforementioned, and which were previously indexed on the Wilson Library Literature and Information Science Full Text from 1998 to 2008. The journals are characterized by containing a large number of papers that deals with the issue of collections in university libraries, as well as by the year of highest production in regard to such issue - in other words, the year with the highest number of publications. The authors who have published papers in those journals are characterized according to: professional formation and action, institution connections, gender, and type of authorship. Also, the authors’ approach to the central issue is categorized, and a qualitative analysis of the content is made based on diverging and/or converging arguments. Through the analysis of the selected journals, it was possible to delineate the authors’ characteristics as well as that of their approach on the issue of university library collections, who, in this sense, have participated on the construction of Knowledge Engineering and Information Sciences concepts throughout the world.

Ahmed, Hussam; Chateauneuf, Alaa

2014-01-01

The reliability validation of engineering products and systems is mandatory for choosing the best cost-effective design among a series of alternatives. Decisions at early design stages have a large effect on the overall life cycle performance and cost of products. In this paper, an optimization-based formulation is proposed by coupling the costs of product design and validation testing, in order to ensure the product reliability with the minimum number of tests. This formulation addresses the question about the number of tests to be specified through reliability demonstration necessary to validate the product under appropriate confidence level. The proposed formulation takes into account the product cost, the failure cost and the testing cost. The optimization problem can be considered as a decision making system according to the hierarchy of structural reliability measures. The numerical examples show the interest of coupling design and testing parameters. - Highlights: • Coupled formulation for design and testing costs, with lifetime degradation. • Cost-effective testing optimization to achieve reliability target. • Solution procedure for nested aleatoric and epistemic variable spaces

This study aimed to compare scientific production by providing quantitative evaluation of science output in five Western Iranian Medical Universities including Hamedan, Ilam, Kermanshah, Kurdistan and Lorestan University of Medical Sciences using scientometrics indicators based on data indexed in Scopus for period between the years 2010 to 2014. In this scientometric study data were collected using Scopus database. Both searching and analyzing features of Scopus were used to data retrieval and analysis. We used Scientometrics indicators including number of publications, number of citations, nationalization index (NI), Internationalization Index (INI), H-index, average number of citations per paper, and growth index. Five Western Iranian Universities produced over 3011 articles from 2010 to 2014. These articles were cited 7158 times with an average rate of 4.2 citations per article. H- Index of under study universities are varying from 14 to 30. Ilam University of Medical Sciences had the highest international collaboration with an INI of 0.33 compared to Hamedan and Kermanshah universities with INI of 0.20 and 0.16 respectively. The lowest international collaboration belonged to Lorestan University of Medical Sciences (0.07). The highest Growth Index belonged to Kurdistan University of Medical Sciences (69.7). Although scientific production of five Western Iranian Medical Universities was increasing, but this trend was not stable. To achieve better performance it is recommended that five Western Iranian Universities stabilize their budgeting and investment policies in research.

MATERIALS AND METHODS: In this study, 40 Asian countries were included. The information regarding Asian countries, their GDP per capita, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the bibliometric indicators, including total number of research documents, citations per document and H-index in various science and social sciences subjects during the period 1996-2011. The main sources for information were World Bank, SCI-mago/Scopus and Web of Science; Thomson Reuters. RESULTS: The mean per capita GDP for all the Asian countries is 14448.31±2854.40 US$, yearly per capita spending on R&D 0.64±0.16 US$, number of universities 72.37±18.32 and mean number of ISI indexed journal per country is 17.97±7.35. The mean of research documents published in various science and social science subjects among all the Asian countries during the period 1996-2011 is 158086.92±69204.09; citations per document 8.67±0.48; and H-index 122.8±19.21. Spending on R&D, number of universities and indexed journals have a positive correlation with number of published documents, citations per document and H-index in various science and social science subjects. However, there was no association between the per capita GDP and research outcomes. CONCLUSION: The Asian countries who spend more on R&D have a large number of universities and scientific indexed journals produced more in research outcomes including total number of research publication, citations per documents and H-index in various science and social science subjects.

This study aimed to compare the impact of Gross Domestic Product (GDP) per capita, spending on Research and Development (R&D), number of universities, and Indexed Scientific Journals on total number of research documents (papers), citations per document and Hirsch index (H-index) in various science and social science subjects among Asian countries. In this study, 40 Asian countries were included. The information regarding Asian countries, their GDP per capita, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the bibliometric indicators, including total number of research documents, citations per document and H-index in various science and social sciences subjects during the period 1996-2011. The main sources for information were World Bank, SCI-mago/Scopus and Web of Science; Thomson Reuters. The mean per capita GDP for all the Asian countries is 14448.31±2854.40 US$, yearly per capita spending on R&D 0.64±0.16 US$, number of universities 72.37±18.32 and mean number of ISI indexed journal per country is 17.97±7.35. The mean of research documents published in various science and social science subjects among all the Asian countries during the period 1996-2011 is 158086.92±69204.09; citations per document 8.67±0.48; and H-index 122.8±19.21. Spending on R&D, number of universities and indexed journals have a positive correlation with number of published documents, citations per document and H-index in various science and social science subjects. However, there was no association between the per capita GDP and research outcomes. The Asian countries who spend more on R&D have a large number of universities and scientific indexed journals produced more in research outcomes including total number of research publication, citations per documents and H-index in various science and social science subjects.

18. Perturbative Universality in Soft Particle Production

CERN Document Server

Khoze, V A; Ochs, Wolfgang; Khoze, Valery A.; Lupia, Sergio; Ochs, Wolfgang

1998-01-01

The spectrum of partons in a QCD jet becomes independent of the primary energy in the low momentum limit. This follows within the perturbative QCD from the colour coherence in soft gluon branching. Remarkably, the hadrons follow such behaviour closely, suggesting the parton hadron duality picture to be appropriate also for the low momentum particles. More generally, this scaling property holds for particles of low transverse and arbitrary longitudinal momentum, which explains an old experimental observation (fan invariance''). Further tests of the perturbatively based picture for soft particle production are proposed for three-jet events in e+e- annihilation and di-jet production events in gamma p, gamma-gamma and p\\bar p collisions. They are based upon the difference in the intensity of the soft radiation from primary q\\bar q and gg antennae.

20. STATE INVESTMENT IN SCIENCE AND SCIENTIFIC PRODUCTIVITY OF UNIVERSITIES

Directory of Open Access Journals (Sweden)

2016-06-01

Full Text Available State investment in service activities of the public sector, as well as the financial returns analyzed from the aspect of service effectiveness and utilization of public goods, can be considered as one of the most significant dilemmas, especially in the field of education. When analyzing state investments, through investment in education and development of the university, we can conclude that state investments in scientific productivity of universities fall into one of the main future frameworks of measurability of universities efficiency. This criterion cannot be taken as the most important since universities are fundamentally divided into teaching and research activities. However, the concept of determination of the productivity of universities, from the aspect of the scientific activities of the teaching staff, has an increasingly important role due to the specified global criteria and conditions for career advancement of the teaching staff and positioning of the university in the education market. This paper intends to give the overview of the current situation of universities in Croatia, as well as the trends that would point out state role in financing of universities and indicate coherent criteria regarding the financing of scientific productivity of teaching stuff.

1. Knowledge production as organizational learning: The case of Danish universities

DEFF Research Database (Denmark)

Elkjær, Bente

2018-01-01

One of the political means to encourage competitive knowledge production in universities is to employ strategic management, but is this a promising method? I explore this question through a practice-based and pragmatist version of organisational learning as well as the Nordic tradition for work...... participation from ‘below’ as a prerequisite for learning and innovation. Research leadership that works in collaboration with peers rather than maintaining a focus on strategic management could be an answer to more competitive and sustainable knowledge production....... and education to suggest ways for sustainable knowledge production. University scholars not only participate in research practices at their home university but also in worldwide knowledge production driven by passions for specific fields of inquiry. Further, the Nordic countries have a tradition for active...

7. Reconstructing the metric of the local Universe from number counts observations

Energy Technology Data Exchange (ETDEWEB)

Vallejo, Sergio Andres [ICRANet, Piazza della Repubblica 10, I-65122 Pescara (Italy); Romano, Antonio Enea, E-mail: antonio.enea.romano@cern.ch [Theoretical Physics Department, CERN, CH-1211 Geneva 23 (Switzerland)

2017-10-01

Number counts observations available with new surveys such as the Euclid mission will be an important source of information about the metric of the Universe. We compute the low red-shift expansion for the energy density and the density contrast using an exact spherically symmetric solution in presence of a cosmological constant. At low red-shift the expansion is more precise than linear perturbation theory prediction. We then use the local expansion to reconstruct the metric from the monopole of the density contrast. We test the inversion method using numerical calculations and find a good agreement within the regime of validity of the red-shift expansion. The method could be applied to observational data to reconstruct the metric of the local Universe with a level of precision higher than the one achievable using perturbation theory.

8. A universal algorithm to generate pseudo-random numbers based on uniform mapping as homeomorphism

International Nuclear Information System (INIS)

Fu-Lai, Wang

2010-01-01

A specific uniform map is constructed as a homeomorphism mapping chaotic time series into [0,1] to obtain sequences of standard uniform distribution. With the uniform map, a chaotic orbit and a sequence orbit obtained are topologically equivalent to each other so the map can preserve the most dynamic properties of chaotic systems such as permutation entropy. Based on the uniform map, a universal algorithm to generate pseudo random numbers is proposed and the pseudo random series is tested to follow the standard 0–1 random distribution both theoretically and experimentally. The algorithm is not complex, which does not impose high requirement on computer hard ware and thus computation speed is fast. The method not only extends the parameter spaces but also avoids the drawback of small function space caused by constraints on chaotic maps used to generate pseudo random numbers. The algorithm can be applied to any chaotic system and can produce pseudo random sequence of high quality, thus can be a good universal pseudo random number generator. (general)

11. Biofuel Production Initiative at Claflin University Final Report

Energy Technology Data Exchange (ETDEWEB)

Chowdhury, Kamal

2011-07-20

For US transportation fuel independence or reduced dependence on foreign oil, the Federal Government has mandated that the country produce 36 billion gallons (bg) of renewable transportation fuel per year for its transportation fuel supply by 2022. This can be achieved only if development of efficient technology for second generation biofuel from ligno-cellulosic sources is feasible. To be successful in this area, development of a widely available, renewable, cost-effective ligno-cellulosic biomass feedstock that can be easily and efficiently converted biochemically by bacteria or other fast-growing organisms is required. Moreover, if the biofuel type is butanol, then the existing infrastructure to deliver fuel to the customer can be used without additional costs and retrofits. The Claflin Biofuel Initiative project is focused on helping the US meet the above-mentioned targets. With support from this grant, Claflin University (CU) scientists have created over 50 new strains of microorganisms that are producing butanol from complex carbohydrates and cellulosic compounds. Laboratory analysis shows that a number of these strains are producing higher percentages of butanol than other methods currently in use. All of these recombinant bacterial strains are producing relatively high concentrations of acetone and numerous other byproducts as well. Therefore, we are carrying out intense mutations in the selected strains to reduce undesirable byproducts and increase the desired butanol production to further maximize the yield of butanol. We are testing the proof of concept of producing pre-industrial large scale biobutanol production by utilizing modifications of currently commercially available fermentation technology and instrumentation. We have already developed an initial process flow diagram (PFD) and selected a site for a biobutanol pilot scale facility in Orangeburg, SC. With the recent success in engineering new strains of various biofuel producing bacteria at CU

To determine the scientific production of Research Vice-chancellors at Peruvian universities that have medical schools, as well as their academic degrees as an indirect way to evaluate their suitability for the position they hold. We searched all Peruvian universities that register medical schools. Of these, the scientific production of the universities registered in SCOPUS was identified in September of the 2016. The scientific production of the vice chancellors of investigation of these faculties of medicine was determined through the search of its scientific publications registered in SCOPUS and those reported in the National Registry of Researchers in Science and Technology. Academic degrees were obtained from the database of the National Superintendence of Higher University Education. The sample included 28 research vice chancellors. Only 4/28 had any publications. The average number of articles published by the vice chancellors of research was 1.71, the number of citations 23.1 on average and the H index 0.64. Besides, 22 Vice-chancellors of research had the degree of doctor, four had the degree of bachelor and two the degree of master. The scientific production of research vice chancellors is poor. The required academic grade requirement for the position is not met in all cases. It is likely that, having no research experience, his leadership in directing a university's research policies may be questioned.

14. Production of number states of the electomagnetic field

Cummings, F.W.; Rajagopal, A.K.

1989-04-01

It has been demonstrated recently that it is possible to generate a pure number state, or Fock state, of the electromagnetic field in a resonant cavity when a ''micromaser'' is operated under the appropriate conditions. This prospect is examined here by a direct analysis of the equation for the density-matrix-governing operation of the lossless micromaser, without having to solve the equation or perform numerical analyses. This model micromaser affords a unique example of an open quantum system whose von Neumann entropy may increase at first, but must subsequently vanish.

16. Universality of spectrum of passive scalar variance at very high Schmidt number in isotropic steady turbulence

Science.gov (United States)

Gotoh, Toshiyuki

2012-11-01

Spectrum of passive scalar variance at very high Schmidt number up to 1000 in isotropic steady turbulence has been studied by using very high resolution DNS. Gaussian random force and scalar source which are isotropic and white in time are applied at low wavenumber band. Since the Schmidt number is very large, the system was integrated for 72 large eddy turn over time for the system to forgot the initial state. It is found that the scalar spectrum attains the asymptotic k-1 spectrum in the viscous-convective range and the constant CB is found to be 5.7 which is larger than 4.9 obtained by DNS under the uniform mean scalar gradient. Reasons for the difference are inferred as the Reynolds number effect, anisotropy, difference in the scalar injection, duration of time average, and the universality of the constant is discussed. The constant CB is also compared with the prediction by the Lagrangian statistical theory for the passive scalar. The scalar spectrum in the far diffusive range is found to be exponential, which is consistent with the Kraichnan's spectrum. However, the Kraichnan spectrum was derived under the assumption that the velocity field is white in time, therefore theoretical explanation of the agreement needs to be explored.

St-Jacques, J. M.; McGee, S.; Janze, R.; Longman, M.; Pete, S.; Starblanket, N.

2016-12-01

Canadian Indigenous people are an extremely poorly represented group in STEM today due to major barriers in obtaining a high school and then a university education. Approximately 10% of the undergraduate student population out of a total 12,600 students at the University of Regina, Regina, Saskatchewan, is First Nations, Métis or Inuit. The university is located in a catchment region where 30% of the population is First Nations or Métis. Approximately 100 students majoring in the sciences, mathematics and engineering have self-declared themselves to be Indigenous. For the past two years, we have been running a pilot project, the Initiative to Support and Increase the Number of Indigenous Students in the Sciences, Mathematics and Engineering at the Aboriginal Student Centre, with financial support from the Deans of Science and Engineering. We provide student networking lunches, Indigenous scientist and engineer speakers and mentors and supplemental tutoring. Our program is actively supported and guided by Elder Noel Starblanket, former president of the National Indian Brotherhood (now the Assembly of First Nations). Our students are greatly interested in the health and environmental sciences (particularly water quality), with a sprinkling of physics, mathematics and engineering majors. Our students have gone on to graduate work with prestigious scholarships and a paid internship in engineering. We report here on various lessons learned: the involvement of elders is key, as is the acceptance of non-traditional academic paths, and any STEM support program must respect Indigenous culture. There is great interest in science and engineering on the part of these students, if scientists and engineers are willing to listen and learn to talk with these students on their own terms.

The PHOBOS experiment at RHIC has measured the multiplicity of primary charged particles as a function of centrality and pseudorapidity in Au+Au collisions at sqrt(s_NN) = 19.6, 130 and 200 GeV. Two kinds of universal behavior are observed in charged particle production in heavy ion collisions. The first is that forward particle production, over a range of energies, follows a universal limiting curve with a non-trivial centrality dependence. The second arises from comparisons with pp/pbar-p and e+e- data. N_tot/(N_part/2) in nuclear collisions at high energy scales with sqrt(s) in a similar way as N_tot in e+e- collisions and has a very weak centrality dependence. This feature may be related to a reduction in the leading particle effect due to the multiple collisions suffered per participant in heavy ion collisions.

Bibliometric analysis may give an objective information about publishing activity, citation rate and collaboration patterns of individuals, groups and institutions. The publication productivity of the present medical staff (79 with specialist degree and 22 residents) in Department of Internal Medicine, University of Zagreb School of Medicine in University Hospital Centre Zagreb was measured by the number of papers indexed by Medline, their impact was measured by the number of times these papers had subsequently been cited in the medical literature, while the collaboration pattern was estimated by the authors' addresses listed in the papers. PubMed database was a source for verifying the bibliographic data, and the citation data were searched via Thomson Web of Scence (WoS) platform. There were a total of 1182 papers, published from 1974 to date. The number of papers per author ranged from 0 to 252. Sixty of papers were published in English, and 39% in Croatian language. The roughly equal share was published in local and foreign journals. The RCT studies and practice guidelines were among the most cited papers and were at the same time published by the highly ranked journals. The collaboration analysis confirmed the extensive involment in the international multicentric clinical trials as well as in the development of international/local practice guidelines.

4. Resonant Production of Sterile Neutrinos in the Early Universe

Science.gov (United States)

Gilbert, Lauren; Grohs, Evan; Fuller, George M.

2016-06-01

This study examines the cosmological impacts of a light resonantly produced sterile neutrino in the early universe. Such a neutrino could be produced through lepton number-driven Mikheyev-Smirnov-Wolfenstein (MSW) conversion of active neutrinos around big bang nucleosynthesis (BBN), resulting in a non-thermal spectrum of both sterile and electron neutrinos. During BBN, the neutron-proton ratio depends sensitively on the electron neutrino flux. If electron neutrinos are being converted to sterile neutrinos, this makes the n/p ratio a probe of possible new physics. We use observations of primordial Yp and D/H to place limits on this process.

Full Text Available Abstract Background The current study was undertaken to examine total hospital costs per patient of a consecutive implantation series of two 3rd generation Left Ventricle Assist Devices (LVAD. Further we analyzed if increased clinical experience would reduce total hospital costs and the gap between costs and the diagnosis related grouped (DRG-reimbursement. Method Cost data of 20 LVAD implantations (VentrAssist™ from 2005-2009 (period 1 were analyzed together with costs from nine patients using another LVAD (HeartWare™ from 2009-June 2011 (period 2. For each patient, total costs were calculated for three phases - the pre-LVAD implantation phase, the LVAD implantation phase and the post LVAD implant phase. Patient specific costs were obtained prospectively from patient records and included personnel resources, medication, blood products, blood chemistry and microbiology, imaging and procedure costs including operating room costs. Overhead costs were registered retrospectively and allocated to the specific patient by predefined allocation keys. Finally, patient specific costs and overhead costs were aggregated into total hospital costs for each patient. All costs were calculated in 2011-prices. We used regression analyses to analyze cost variations over time and between the different devices. Results The average total hospital cost per patient for the pre-LVAD, LVAD and post-LVAD for period 1 was $585, 513 (range 132, 640- 1 247, 299, and the corresponding DRG- reimbursement (2009 was$ 143, 192 . The mean LOS was 54 days (range 12- 127. For period 2 the total hospital cost per patient was $413, 185 (range 314, 540- 622, 664 and the corresponding DRG- reimbursement (2010 was$ 136, 963. The mean LOS was 49 days (range 31- 93. The estimates from the regression analysis showed that the total hospital costs, excluding device costs, per patient were falling as the number of treated patients increased. The estimate from the trend variable was -14

A model of the production of ordinary and dark matter in the decay of a hypothetical antigravitating medium in the form of a condensate of spinless massive particles, which fills the Universe, is proposed. The decays of these particles into baryons, leptons, and dark matter particles are caused by some interaction with the mass scale between the electroweak interaction and the grand unification. The observed dark energy is identified with a portion of the condensate, which has not decayed up to the instant of a measurement. The decay rate of particles of the condensate is expressed through the three parameters - the coupling constant α X , the mass scale M X ; which defines the mass of an X-particle as a mediator of the interaction, and the energy imparted to the decay products. Under the assumption that the decay rate of particles of the condensate is of the same order of magnitude as the Hubble expansion rate, the limits of the possible values of the mass M X are obtained. The cross-sections of the reactions, in which dark matter particles can be produced, are calculated.

The Indian economy is one of the fastest growing economies in the world and the demand for the skilled engineers is increasing. Subsequently the Indian education sector is growing to provide the necessary number of skilled engineers. Current Indian engineering graduates have broad theoretical background but lack in methodological, soft and practical skills. To bridge this gap, the experience lab ideas from the engineering education at “Die Lernfabrik” (learning factory) of the Technische Universität Braunschweig (TU Braunschweig) is transferred to the Birla Institute of Technology and Science in Pilani (BITS Pilani), India. This Lernfabrik successfully strengthened the methodological, soft and practical skills of the TU Braunschweig production-engineering graduates. The target group is discrete manufacturing education with focusing on energy and resource efficiency as well as cyber physical production systems. As the requirements of industry and academia in India differs from Germany, the transfer of the experience lab to the Indian education system needs special attention to realize a successful transfer project. This publication provides a unique approach to systematically transfer the educational concept in Learning Factory from a specific university environment to a different environment in a newly industrialized country. The help of a bilateral university driven practice partnership between the two universities creates a lighthouse for the Indian university environment.

Full Text Available http://dx.doi.org/10.5007/1518-2924.2016v21n47p67 The study characterizes the inventions of patents of Brazilian universities concerning authorship and subject area to identify the institutions’ possible departments and areas that concentrate efforts on or are more easily able to produce and achieve the patent grants in Brazil. For the data collection of the universities, we used the E-mec platform; the database of the National Institute of Industrial Property (INPI for the collection of information concerning patents; and the International Patent Classification (IPC to determine the covered knowledge areas. Thus, we analyzed the production of patents by Brazilian region; the universities with patents granted; the number of inventors per patent; the profile of the main inventors; and the patents granted according to the IPC. The results indicate that the characteristics of the patents granted to Brazilian Public Universities belong predominantly to the areas of Chemistry and Metallurgy. They are developed by professors with graduation in Chemistry or Mechanical Engineering and most of them belong to the State University of Campinas.

10. Investigation of science production in Iran’s type I universities of medical sciences, a 6-year assessment

Directory of Open Access Journals (Sweden)

2014-07-01

Full Text Available Introduction: Science production is one of the main dimensions of sustainable development in any country. Thus, universities as the major centers for science production play a key role in development. The present study aimed to assess the trend of science production in Iran’s type I universities of medical sciences from 2007 to 2012. Method: In this study, the universities’ scores of empowering, governance and leadership, science production, student researches, and number of published articles were computed based on the evaluations of universities of medical sciences by the Ministry of Health, Treatment, and Medical Education from 2007 to 2012. Then, the data were analyzed using descriptive statistics and the figures were drawn by Excel software. Results: This study assessed science production in Iran’s type I universities of medical sciences and analyzed each university’s proportion in publication of articles. According to the results, most of the published articles were affiliated to Tehran University of Medical Sciences. However, considering the role of number of faculty members, different results were obtained. With respect to the evaluation raw scores, Isfahan University of Medical Sciences showed a considerable reduction of scores in 2012, while other universities had a constant or ascending trend. Besides, indexed articles followed an ascending trend in all the universities and most of the articles had been published in index 1. Conclusion: Similar to other studies, the findings of this study revealed an increase in science productions in Iran through the recent years. Yet, the highest scores of the studied indexes, except for student researches, were related to Tehran University of Medical Sciences. This great difference between this university and other universities might be due to accumulation of specific potentials and forces in this region. Overall, science productions followed an ascending trend in all type I universities of

Since the National Treatment Purchase Fund (NTPF) scheme was introduced in 2002, public patients waiting longer than three months for investigations and treatment are offered care in the private medical sector. Our aim was to assess the impact of the NTPF scheme on the number of training cases performed at University Hospital Galway (UHG). The number and type of urological procedures performed in the private medical sector under the NTFP scheme in 2008 were obtained from the UHG waiting list office. The number of these procedures performed on public patients by trainees at UHG in 2008 was determined retrospectively by reviewing theatre records. A significant number of core urology procedures were performed in the private sector via the NTPF scheme. Cancer centre designation and implementation of the EWTD will also place further pressures on urological training opportunities in Ireland.

Hybrid Structural Reliability Analysis under Multisource Uncertainties Based on Universal Grey Numbers Directory of Open Access Journals (Sweden) Xingfa Yang 2018-01-01 Full Text Available Nondeterministic parameters of certain distribution are employed to model structural uncertainties, which are usually assumed as stochastic factors. However, model parameters may not be precisely represented due to some factors in engineering practices, such as lack of sufficient data, data with fuzziness, and unknown-but-bounded conditions. To this end, interval and fuzzy parameters are implemented and an efficient approach to structural reliability analysis with random-interval-fuzzy hybrid parameters is proposed in this study. Fuzzy parameters are first converted to equivalent random ones based on the equal entropy principle. 3σ criterion is then employed to transform the equivalent random and the original random parameters to interval variables. In doing this, the hybrid reliability problem is transformed into the one only with interval variables, in other words, nonprobabilistic reliability analysis problem. Nevertheless, the problem of interval extension existed in interval arithmetic, especially for the nonlinear systems. Therefore, universal grey mathematics, which can tackle the issue of interval extension, is employed to solve the nonprobabilistic reliability analysis problem. The results show that the proposed method can obtain more conservative results of the hybrid structural reliability. 18. Classical transitions with the topological number changing in the early Universe Science.gov (United States) Gani, Vakhid A.; Kirillov, Alexander A.; Rubin, Sergey G. 2018-04-01 We consider classical dynamics of two real scalar fields within a model with the potential having a saddle point. The solitons of such model are field configurations that have the form of closed loops in the field space. We study the formation and evolution of these solitons, in particular, the conditions at which they could be formed even when the model potential has only one minimum. These non-trivial field configurations represent domain walls in the three-dimensional physical space. The set of these configurations can be split into disjoint equivalence classes. We provide a simple expression for the winding number of an arbitrary closed loop in the field space and discuss the transitions that change the winding number. We also show that non-trivial field configurations could be responsible for the energy density excess that could evade the CMB constraints but could be important at scales which are responsible for the formation of galaxies and the massive primordial black holes. 19. THE DYNAMICS OF THE ROMANIAN UNIVERSITIES GRADUATES NUMBER IN THE 2005-2010 PERIOD Directory of Open Access Journals (Sweden) Popovici Adina 2011-12-01 Full Text Available In the context of the European single market, where information, capitals, persons, goods and services circulate free and fast, where economic rationality is different at the global level from the national one, radical mutations occur in each member state's strategy with regard to the educational system. Therefore, the Romanian educational system, especially the Romanian higher education must correlate the graduates number with the Romanian and EU labour force requirements, and take into account the necessities imposed by the participation at international competition. On the other hand, a country's economic and social development level depends very much on its citiyens' educational level, especially in nowadays knowledge-based society, which is a society of life-long-learning. 20. The scientific production in health and biological sciences of the top 20 Brazilian universities Directory of Open Access Journals (Sweden) R. Zorzetto 2006-12-01 Full Text Available Brazilian scientific output exhibited a 4-fold increase in the last two decades because of the stability of the investment in research and development activities and of changes in the policies of the main funding agencies. Most of this production is concentrated in public universities and research institutes located in the richest part of the country. Among all areas of knowledge, the most productive are Health and Biological Sciences. During the 1998-2002 period these areas presented heterogeneous growth ranging from 4.5% (Pharmacology to 191% (Psychiatry, with a median growth rate of 47.2%. In order to identify and rank the 20 most prolific institutions in these areas, searches were made in three databases (DataCAPES, ISI and MEDLINE which permitted the identification of 109,507 original articles produced by the 592 Graduate Programs in Health and Biological Sciences offered by 118 public universities and research institutes. The 20 most productive centers, ranked according to the total number of ISI-indexed articles published during the 1998-2003 period, produced 78.7% of the papers in these areas and are strongly concentrated in the Southern part of the country, mainly in São Paulo State. 1. Academic productivity and its relationship to physician salaries in the University of California Healthcare System. Science.gov (United States) Fijalkowski, Natalia; Zheng, Luo Luo; Henderson, Michael T; Moshfeghi, Andrew A; Maltenfort, Mitchell; Moshfeghi, Darius M 2013-07-01 To evaluate whether physicians with higher academic productivity, as measured by the number of publications in Scopus and the Scopus Hirsch index (h-index), earn higher salaries. This was a cross-sectional study. Participants were ophthalmologists, otolaryngologists, neurosurgeons, and neurologists classified as "top earners" (>$100,000 annually) within the University of California (UC) healthcare system in 2008. Bibliometric searches on Scopus were conducted to retrieve the total number of publications and Hirsch indices (h-index), a measure of academic productivity. The association between the number of publications and h-index on physicians' total compensation was determined with multivariate regression models after controlling for the four specialties (ophthalmology, otolaryngology, neurosurgery, and neurology), the five institutions (UC San Francisco, UC Los Angeles, UC San Diego, UC Irvine, and UC Davis), and academic rank (assistant professor, associate professor, and professor). The UC healthcare system departments reported 433 faculty physicians among the four specialties, with 71.6% (n = 310) earning more than $100,000 in 2008 and classifying as top earners. After controlling for the specialty, institution, and ranking, there was a significant association between the number of publications on salary (P Scopus number of publications and h-index were correlated (P Scopus h-index was of borderline significance in predicting physician salary (P = 0.12). Physicians with higher Scopus publications had higher total salaries across all four specialties.

Explaining the large numbers by a hierarchy of ''universes'': a unified theory of strong and gravitational interactions International Nuclear Information System (INIS) Caldirola, P.; Recami, E. 1978-01-01 By assuming covariance of physical laws under (discrete) dilatations, strong and gravitational interactions have been described in a unified way. In terms of the (additional, discrete) ''dilatational'' degree of freedom, our cosmos as well as hadrons can be considered as different states of the same system, or rather as similar systems. Moreover, a discrete hierarchy can be defined of ''universes'' which are governed by force fields with strengths inversely proportional to the ''universe'' radii. Inside each ''universe'' an equivalence principle holds, so that its characteristic field can be geometrized there. It is thus easy to derive a whole ''numerology'', i.e. relations among numbers analogous to the so-called Weyl-Eddington-Dirac ''large numbers''. For instance, the ''Planck mass'' happens to be nothing but the (average) magnitude of the strong charge of the hadron quarks. However, our ''numerology'' connects the (gravitational) macrocosmos with the (strong) microcosmos, rather than with the electromagnetic ones (as, e.g., in Dirac's version). Einstein-type scaled equations (with ''cosmological'' term) are suggested for the hadron interior, which - incidentally - yield a (classical) quark confinement in a very natural way and are compatible with the ''asymptotic freedom''. At last, within a ''bi-scale'' theory, further equations are proposed that provide a priori a classical field theory of strong interactions (between different hadrons). The relevant sections are 5.2, 7 and 8. (author) 3.

Quantum cost optimized design of 4-bit reversible universal shift register using reduced number of logic gate Science.gov (United States) Maity, H.; Biswas, A.; Bhattacharjee, A. K.; Pal, A. In this paper, we have proposed the design of quantum cost (QC) optimized 4-bit reversible universal shift register (RUSR) using reduced number of reversible logic gates. The proposed design is very useful in quantum computing due to its low QC, less no. of reversible logic gate and less delay. The QC, no. of gates, garbage outputs (GOs) are respectively 64, 8 and 16 for proposed work. The improvement of proposed work is also presented. The QC is 5.88% to 70.9% improved, no. of gate is 60% to 83.33% improved with compared to latest reported result. 6.

Quantum correlation properties in Matrix Product States of finite-number spin rings Science.gov (United States) Zhu, Jing-Min; He, Qi-Kai 2018-02-01 The organization and structure of quantum correlation (QC) of quantum spin-chains are very rich and complex. Hence the depiction and measures about the QC of finite-number spin rings deserved to be investigated intensively by using Matrix Product States(MPSs) in addition to the case with infinite-number. Here the dependencies of the geometric quantum discord(GQD) of two spin blocks on the total spin number, the spacing spin number and the environment parameter are presented in detail. We also compare the GQD with the total correlation(TC) and the classical correlation(CC) and illustrate its characteristics. Predictably, our findings may provide the potential of designing the optimal QC experimental detection proposals and pave the way for the designation of optimal quantum information processing schemes. 10. Determining the number of kanbans for dynamic production systems: An integrated methodology Directory of Open Access Journals (Sweden) Özlem Uzun Araz 2016-08-01 Full Text Available Just-in-time (JIT is a management philosophy that reduces the inventory levels and eliminates manufacturing wastes by producing only the right quantity at the right time. A kanban system is one of the key elements of JIT philosophy. Kanbans are used to authorize production and to control movement of materials in JIT systems. In Kanban systems, the efficiency of the manufacturing system depends on several factors such as number of kanbans, container size etc. Hence, determining the number of kanbans is a critical decision in Kanban systems. The aim of this study is to develop a methodology that can be used in order to determine the number of kanbans in a dynamic production environment. In this methodology, the changes in system state is monitored in real time manner, and the number of the kanbans are dynamically re-arranged. The proposed methodology integrates simulation, neural networks and Mamdani type fuzzy inference system. The methodology is modelled in simulation environment and applied on a hypothetic production system. We also performed several comparisons for different control policies to show the effectiveness of the proposed methodology. 11. Coverage, universal access and equity in health: a characterization of scientific production in nursing. Science.gov (United States) Mendoza-Parra, Sara 2016-01-01 to characterize the scientific contribution nursing has made regarding coverage, universal access and equity in health, and to understand this production in terms of subjects and objects of study. this was cross-sectional, documentary research; the units of analysis were 97 journals and 410 documents, retrieved from the Web of Science in the category, "nursing". Descriptors associated to coverage, access and equity in health, and the Mesh thesaurus, were applied. We used bibliometric laws and indicators, and analyzed the most important articles according to amount of citations and collaboration. the document retrieval allowed for 25 years of observation of production, an institutional and an international collaboration of 31% and 7%, respectively. The mean number of coauthors per article was 3.5, with a transience rate of 93%. The visibility index was 67.7%, and 24.6% of production was concentrated in four core journals. A review from the nursing category with 286 citations, and a Brazilian author who was the most productive, are issues worth highlighting. the nursing collective should strengthen future research on the subject, defining lines and sub-lines of research, increasing internationalization and building it with the joint participation of the academy and nursing community. 12.

University of Maine Integrated Forest Product Refinery (IFPR) Technology Research Energy Technology Data Exchange (ETDEWEB) Pendse, Hemant P. 2010-11-23 This project supported research on science and technology that forms a basis for integrated forest product refinery for co-production of chemicals, fuels and materials using existing forest products industry infrastructure. Clear systems view of an Integrated Forest Product Refinery (IFPR) allowed development of a compelling business case for a small scale technology demonstration in Old Town ME for co-production of biofuels using cellulosic sugars along with pulp for the new owners of the facility resulting in an active project on Integrated Bio-Refinery (IBR) at the Old Town Fuel & Fiber. Work on production of advanced materials from woody biomass has led to active projects in bioplastics and carbon nanofibers. A lease for 40,000 sq. ft. high-bay space has been obtained to establish a Technology Research Center for IFPR technology validation on industrially relevant scale. UMaine forest bioproducts research initiative that began in April 2006 has led to establishment of a formal research institute beginning in March 2010. 15.

The University of Missouri Research Reactor, its fuel and productivity International Nuclear Information System (INIS) Brugger, R.M.; Schlapper, G.A.; Alger, D.M. 1993-01-01 This paper describes the University of Missouri Research Reactor (MURR) and presents a summary of contributions to education, research, and service. These efforts have helped offset the impact on the U.S. economy of research from other countries. Special emphasis is placed on fuel design developments that have allowed MuRR to keep the cost megawatt day (MWD) of fuel essentially constant. Also noted is the fact that the United States has missed some research opportunities because of a hold-the-line attitude. The slipping position of U.S. research reactors is compared with the rest of the world. As will be further outlined in the text, the MURR cannot (with available technology) decrease its U-235 enrichment level and maintain present research capabilities and fuel cycle costs. Data is presented to show how MURR, if permitted to use advanced fuel technology, could reduce fuel fabrication costs and onsite U-235 inventory. In addition it is shown that MURR could increase its capabilities provided that arbitrary institutional limits are removed 17.

Science and production laboratories: integration between the industry and universities International Nuclear Information System (INIS) Anokhin, A.N.; Sivokon', V.P.; Rakitin, I.D. 2010-01-01 Industry laboratories provide students with an opportunity to resolve real serious tasks and be exposed to a wide range of professional activities. Staffing in the Russian nuclear industry is a serious concern. There is a shortage of experienced specialists, and it is impossible to train a replacement for them quickly. Creation of a true professional is a long and thorough process, whereby the amount of knowledge and experience very slowly transforms into quality of performance. The authors underline that the teacher of a modern technical university should not and must not act as a middle man between the textbook and the students. The teacher must instead become a holder of the latest technological knowledge, which he will pass to students during lessons. The authors report on the ERGOLAB, a problematic science and research laboratory for ergonomic research and development in the nuclear field. Ergonomic support is one of the more important factors in the prevention of human errors, maintenance of professional health and improvement of performance efficiency [ru 19. Monitoring a large number of pesticides and transformation products in water samples from Spain and Italy. Science.gov (United States) Rousis, Nikolaos I; Bade, Richard; Bijlsma, Lubertus; Zuccato, Ettore; Sancho, Juan V; Hernandez, Felix; Castiglioni, Sara 2017-07-01 Assessing the presence of pesticides in environmental waters is particularly challenging because of the huge number of substances used which may end up in the environment. Furthermore, the occurrence of pesticide transformation products (TPs) and/or metabolites makes this task even harder. Most studies dealing with the determination of pesticides in water include only a small number of analytes and in many cases no TPs. The present study applied a screening method for the determination of a large number of pesticides and TPs in wastewater (WW) and surface water (SW) from Spain and Italy. Liquid chromatography coupled to high-resolution mass spectrometry (HRMS) was used to screen a database of 450 pesticides and TPs. Detection and identification were based on specific criteria, i.e. mass accuracy, fragmentation, and comparison of retention times when reference standards were available, or a retention time prediction model when standards were not available. Seventeen pesticides and TPs from different classes (fungicides, herbicides and insecticides) were found in WW in Italy and Spain, and twelve in SW. Generally, in both countries more compounds were detected in effluent WW than in influent WW, and in SW than WW. This might be due to the analytical sensitivity in the different matrices, but also to the presence of multiple sources of pollution. HRMS proved a good screening tool to determine a large number of substances in water and identify some priority compounds for further quantitative analysis. Copyright © 2017 Elsevier Inc.

Short-range order and local conservation of quantum numbers in multiparticle production International Nuclear Information System (INIS) Le Bellac, M. 1976-01-01 These lectures discuss the implications of the hypotheses of short-range order (SRO) and local conservation of quantum numbers (LCQN) for multiple production of elementary particles at high energies. The consequences of SRO for semi-inclusive correlations and the distribution of rapidity gaps are derived, essentially in the framework of the cluster model. Then the experimental status of local conservation of charge and transverse momentum is reviewed. Finally, by making use of the unitarity relation, it is shown that LCQN has important consequences for the elastic amplitude. The derivation is given both in a model-independent way, and in specific multiperiheral models. (Author) 1. Displaced squeezed number states: Position space representation, inner product, and some applications DEFF Research Database (Denmark) Møller, Klaus Braagaard; Jørgensen, Thomas Godsk; Dahl, Jens Peder 1996-01-01 For some applications the overall phase of a quantum state is crucial. For the so-called displaced squeezed number state (DSN), which is a generalization of the well-known squeezed coherent state, we obtain the position space representation with the correct overall phase, from the dynamics...... in a harmonic potential. The importance of the overall phase is demonstrated in the context of characteristic or moment generating functions. For two special cases the characteristic function is shown to be computable from the inner product of two different DSNs.... 2. ENTROPY PRODUCTION IN COLLISIONLESS SYSTEMS. II. ARBITRARY PHASE-SPACE OCCUPATION NUMBERS International Nuclear Information System (INIS) Barnes, Eric I.; Williams, Liliya L. R. 2012-01-01 We present an analysis of two thermodynamic techniques for determining equilibria of self-gravitating systems. One is the Lynden-Bell (LB) entropy maximization analysis that introduced violent relaxation. Since we do not use the Stirling approximation, which is invalid at small occupation numbers, our systems have finite mass, unlike LB's isothermal spheres. (Instead of Stirling, we utilize a very accurate smooth approximation for ln x!.) The second analysis extends entropy production extremization to self-gravitating systems, also without the use of the Stirling approximation. In addition to the LB statistical family characterized by the exclusion principle in phase space, and designed to treat collisionless systems, we also apply the two approaches to the Maxwell-Boltzmann (MB) families, which have no exclusion principle and hence represent collisional systems. We implicitly assume that all of the phase space is equally accessible. We derive entropy production expressions for both families and give the extremum conditions for entropy production. Surprisingly, our analysis indicates that extremizing entropy production rate results in systems that have maximum entropy, in both LB and MB statistics. In other words, both thermodynamic approaches lead to the same equilibrium structures. 3. Mitigation of naphthenate related production upsets in high TAN (Total Acid Number) crude oil Energy Technology Data Exchange (ETDEWEB) Ostojic, Nik [Maersk Oil, Copenhagen (Denmark); Vijn, Pieter; Reiners, Robert [Champion Technologies Europe BV, Delden (Netherlands) 2012-07-01 This paper describes a strategy for prediction, evaluation and mitigation of calcium naphthenate related production problems. Developing fields with acidic crude in the North Sea, West Africa, Bohai Bay (China) and Brazil is becoming more common in recent years. The high acid crude contains a considerable amount of naphthenic acids, typically having a Total Acid Number (TAN) higher than 0.5 mg KOH/g. Formation of either hard type 'calcium naphthenate precipitates' or soft type 'sodium carboxylate/emulsions' during crude oil production can lead to severe flow assurance and separation problems. In severe cases this may lead to production shutdowns to clean-up the equipment. A number of different naphthenate mitigation approaches have been published but no one particular approach is considered to be the most efficient as it depends significantly on the particular field conditions. Initially, this problem was addressed by deploying large volumes of (usually organic) acid, but more recently high efficiency low dose naphthenate inhibitors have been introduced. For predicting naphthenate scaling potential, methods were developed to determine the concentration of 1230 Dalton naphthenic tetra acid (ARN acids) in either deposit or crude oil and this information can be used to locate and potentially isolate the problem to a certain reservoir. Also, methods were developed to design suitable low dose naphthenate inhibitors. As these inhibitors are field tested, monitoring is required to ensure the product is performing most efficiently. In cases of tight emulsions however, this is less difficult as the oil dehydration and water quality is affected instantly. Methods were developed to allow monitoring of the calcium naphthenate deposition in field trails, thus allow trending and evaluation of the chemicals performance. After detailed analyses and discussions of the developed methods, a North Sea case history is presented reviewing several years of treating 4.

Research Results Transfer towards the Productive Sector via Research Collaboration in Four Colombian Public Universities Directory of Open Access Journals (Sweden) Maria Eugenia Morales Rubiano 2015-12-01 Full Text Available This article shows the determining factors in the research results transfer towards the productive sector via research collaboration in four Colombian public universities. Thirty heads of units in the aforementioned universities were interviewed, which served to determine eleven cases of study and conduct interviews with thirty-five participants ranging from researchers, participant in formation and business people, in each case, it was found that especially in the last decade universities have turned to creating capacities for research collaboration as well as an openness in participants to create links that not only go in favor of enriching the productive sector but also in strengthening formation and research processes. It was concluded that there is a recent growing interest in the different actors in strengthening the bonds between the universities and the productive sector, though there may be some difficulties in the process of research collaboration due to the lack of an appropriate regulatory framework. 6. Collaborative networks and patent production in Andean Community of Nations universities (UCANS, 2005-2015 Directory of Open Access Journals (Sweden) Carlos Enrique Agüero Aguilar 2017-06-01 Full Text Available The competitiveness and technological development of a region are measured by the degree of innovation supporting them. The quantity and quality of patents generated and applied in production dynamics serve as an element for evaluation. In this sense, universities play a role as generators and transmitters of knowledge. So it is important to identify the level of their collaboration and the trends in terms of technology application in order to establish future policies for development in this sector. This article identifies the degree of collaboration, types of patents, actors (primary and secondary and dynamics of patents produced at the Andean Community of Nations universities during the period 2005-2015 and present in the European Patent Office database. In conclusion, there is a great disparity between CAN universities regarding patent production, so it is necessary to strengthen the collaborative level among universities in this community. Nevertheless, an increase is seen in the production of patents. 7. Variable-flavor-number scheme in analysis of heavy-quark electro-production data International Nuclear Information System (INIS) Alekhin, S.; Bluemlein, J.; Klein, S.; Moch, S. 2009-08-01 We check the impact of the factorization scheme employed in the calculation of the heavy-quark deep-inelastic scattering (DIS) electro-production on the PDFs determined in the NNLO QCD analysis of the world inclusive neutral-current DIS data combined with the ones on the neutrino-nucleon DIS di-muon production and the fixed-target Drell-Yan process. The charm-quark DIS contribution is calculated in the general-mass variable-flavor-number (GMVFN) scheme: At asymptotically large values of the momentum transfer Q it is given by the zero-mass 4-flavor scheme and at the value of Q equal to the charm-quark mass it is smoothly matched with the 3-flavor scheme using the Buza-Matiounine-Smith-van Neerven prescription. The PDFs obtained in this variant of the fit are very similar to the ones obtained in the fit with a 3-flavor scheme employed. Our 5-flavor PDFs derived from the 3-flavor ones using the NNLO matching conditions are used to calculate the rates of W ± /Z and t anti t production at the Tevatron collider and the LHC at NNLO.

High density plasma productions by hydrogen storage electrode in the Tohoku University Heliac International Nuclear Information System (INIS) Utoh, H.; Takahashi, H.; Tanaka, Y.; Takenaga, M.; Ogawa, M.; Shinde, J.; Iwazaki, K.; Shinto, K.; Kitajima, S.; Sasao, M.; Nishimura, K.; Inagaki, S. 2005-01-01 In the Tohoku University Heliac (TU-Heliac), the influence of a radial electric field on improved modes has been investigated by an electrode biasing. In both positive and negative biasing experiments by the stainless steel (SUS) electrode (cold-electron or ion collection), the improvement of plasma confinement was clearly observed. Furthermore, by negative biasing with a hot cathode (electron injection), the radial electric fields can be actively controlled as a consequence of the control of the electrode current I E . By using the electrode made of a hydrogen storage metal, for example Titanium (Ti) or Vanadium (V), the following possibility can be expected: (1) ions accelerated from the positive biased electrode allow the simulation for the orbit loss of high-energy particles, (2) the electrons/neutral- particles injected from the negative biased electrode provide the production of the high- density plasma, if hydrogen are successfully stored in the electrode. In this present work, several methods were tried as the treatment for hydrogen storage. In the case of the Ti electrode biased positively after the treatment, the improvement of plasma confinement was observed in He plasma, which were same as the experimental results of the SUS electrode. However, in the electron density profiles inside the electrode position there was difference between the biased plasma by the Ti electrode and that by the SUS electrode. In some of Ar discharges biased negatively with the Ti electrode after the treatment, the electron density and the line intensity of H α increased about 10 times of those before biasing. This phenomenon has not been observed in the Ar plasma biased by the SUS electrode. This result suggested that the Ti electrode injected electrons/neutral-hydrogen into the plasma. This high-density plasma productions were observed only 1 ∼ 3 times in the one treatment for hydrogen storage. By using a Vanadium (V) electrode, productions of the high-density plasma 12. Research Productivity of Teaching Faculty Members in Nigerian Federal Universities: An Investigative Study Directory of Open Access Journals (Sweden) Olatokunbo Christopher Okiki 2013-12-01 Full Text Available This study assessed the level of research productivity of teaching faculty members in Nigerian federal universities. The findings of the study show that the research productivity of the teaching faculty members in Nigerian federal universities is high in journal publications, technical reports, conference papers, working papers, and occasional papers. The research productivity is higher in Northeast (M=22.53; SD=25.73, and Southwest (M=21.74; SD=87.28, and North Central (M=20.69; SD=31.24 Nigeria. Also, the mean score of information resources availability (M=2.41; SD=0.90 indicates that information resources are readily available to teaching faculty members in Nigerian federal universities. The barriers to research productivity by teaching faculty members in the universities include low Internet bandwidth (M=3.793; SD=1.162 and financial constraint (M=3.543; SD=1.257. Besides, the study has shown the strengths and weaknesses of the teaching faculty members in Nigerian universities in terms of their research output. 13. The Production of FRW Universe and Decay to Particles in Multiverse Science.gov (United States) Ghaffary, Tooraj 2017-09-01 In this study, first, it will be shown that as the Hubble parameter, " H", increases the production cross section for closed and flat Universes increases rapidly at smaller values of " H" and becomes constant for higher values of " H". However in the case of open Universe, the production cross section has been encountered a singularity. Before this singularity, as the H parameter increases, the cross section increases, for smaller H, ( H < 2.5), exhibits a turn-over at moderate values of H, (2.5 < H < 3.5), decreases for larger amount of H After that and for a special value of H, the cross section has been encountered with a singularity. Although the cross section cannot be defined at this singularity but before and after this point, it is certainly equal to zero. After this singularity, the cross section increases rapidly, when H increases. It is shown that if the production cross section of Universe happens before this singularity, it can't achieve to higher values of Hubble parameter after singularity. More over if the production cross section of Universe situates after the singularity, it won't get access to values of Hubble parameter less than the singularity. After that the thermal distribution for particles inside the FRW Universes are obtained. It is found that a large amount of particles are produced near apparent horizon due to their variety in their energy and their probabilities. Finally, comparing the particle production cross sections for flat, closed and open Universes, it is concluded that as the value of k increases, the cross section decreases. 14.

Patient outcome of emergency laparotomy improved with increasing "number of surgeons on-call" in a university hospital: Audit loop. Science.gov (United States) Hussain, Anwar; Mahmood, Fahad; Teng, Chui; Jafferbhoy, Sadaf; Luke, David; Tsiamis, Achilleas 2017-11-01 Emergency laparotomy is a commonly performed high-mortality surgical procedure. The National Emergency Laparotomy Network (NELA) published an average mortality rate of 11.1% and a median length of stay equivalent to 16.3 days in patients undergoing emergency laparotomy. This study presents a completed audit loop after implementing the change of increasing the number of on-call surgeons in the general surgery rota of a university hospital. The aim of this study was to evaluate the outcomes of emergency laparotomy in a single UK tertiary centre after addition of one more consultant in the daily on-call rota. This is a retrospective study involving patients who underwent emergency laparotomy between March to May 2013 (first audit) and June to August 2015 (second audit). The study parameters stayed the same. The adult patients undergoing emergency laparotomy under the general surgical take were included. Appendicectomy, cholecystectomy and simple inguinal hernia repair patients were excluded. Data was collected on patient demographics, ASA, morbidity, 30-day mortality and length of hospital stay. Statistical analysis including logistic regression was performed using SPSS. During the second 3-month period, 123 patients underwent laparotomy compared to 84 in the first audit. Median age was 65(23-93) years. 56.01% cases were ASA III or above in the re-audit compared to 41.9% in the initial audit. 38% patients had bowel anastomosis compared to 35.7% in the re-audit with 4.2% leak rate in the re-audit compared to 16.6% in the first audit. 30-day mortality was 10.50% in the re-audit compared to 21% and median length of hospital stay 11 days in the re-audit compared to 16 days. The lower ASA grade was significantly associated with increased likelihood of being alive, as was being female, younger age and not requiring ITU admission post-operatively. However, having a second on-call consultant was 2.231 times more likely to increase the chances of patients not dying (p = 0 17.

Marketing through instagram influencers: impact of number of followers and product divergence on brand attitude OpenAIRE De Veirman, Marijke; Cauberghe, Veroline; Hudders, Liselot 2016-01-01 Findings from two experiments show that Instagram influencers with high numbers of followers are considered more likeable, mostly because they are considered more popular. Important, only in limited cases, perceptions of popularity due to the influencer’s number of followers, lead to perceptions of opinion leadership. Furthermore, one should also take into account number of followees, as very low numbers of followees might negatively impact popular influencers’ likeability. Also, cooperating ... 7.

Strengthening Knowledge Co-Production Capacity: Examining Interest in Community-University Partnerships Directory of Open Access Journals (Sweden) Kathleen P. Bell 2013-09-01 Full Text Available Building successful, enduring research partnerships is essential for improving links between knowledge and action to address sustainability challenges. Communication research can play a critical role in fostering more effective research partnerships, especially those concerned with knowledge co-production processes. This article focuses on community-university research partnerships and factors that influence participation in the co-production process. We identify specific pathways for improving partnership development through a prospective analytical approach that examines community officials’ interest in partnering with university researchers. Using survey responses from a statewide sample of Maine municipal officials, we conduct a statistical analysis of community-university partnership potential to test a conceptual model of partnership interest grounded in natural resource management theory and environmental communication. Our findings both support and advance prior research on collaborations. Results reveal that belief in the helpfulness of the collaborator to solve problems, institutional proximity, familiarity, perceived problem severity and problem type and trust influence interest in developing community-university partnerships. These findings underscore the benefits of proactively assessing partnership potential prior to forming partnerships and the important roles for communication research within sustainability science, especially with regard to strengthening partnership formation and knowledge co-production processes. 12.

My university. What I learned from the Productive Cooperative Movement to Promotion of Humanistic Family Planning. Science.gov (United States) Kunii, C 1990-07-01 Based on experiences with the Productive Cooperative Movement and the Parasite Control Movement in Japan, the Japanese Family Planning Movement began in April 1954. The resultant private and nonprofit Japan Family Planning Association (JFPA) followed and it served to help Japan achieve its goal of reducing fertility by promoting family planning. It did so by publishing a monthly newsletter on family planning, hosting meetings and national conventions, spreading information via the mass media, and selling contraceptives and educational materials. JFPA earned funding from these sales with no support from the government thereby establishing self dependence and freedom to speak candidly to the government. The JFPA learned that families wanted to improve their standard of living and were willing to limit family size to 2 children. After the birth rate peaked in 1955, the birth rate and the number of illegal abortions decreased. In the 1950s, JFPA joined the International Planned Parenthood Federation and subsequently learned of the problems faced by developing countries. Based on the successful reduction of fertility in Japan and a strong economic base, JFPA and the government were in a position to organize an international cooperation program for family planning. Therefore, the leader of JFPA resigned to found the Japanese Organization for International Cooperation in Family Planning which promotes family planning in developing countries via its integrated family planning, nutrition, and parasite control program. A steering committee composed of leaders from government, universities, and private organizations sets the policies for the program in each country. It is to the Japanese government's advantage to work with private organizations instead of providing all social services because they are flexible and provide administrative stability and national expenses are minimized. 14. Universally applicable design concept of stably controlling an HTGR-hydrogen production system International Nuclear Information System (INIS) Hada, Kazuhiko; Shibata, Taiju; Nishihara, Tetsuo; Shiozawa, Shusaku 1996-01-01 An HTGR-hydrogen production system should be designed to have stable controllability because of a large difference in thermal dynamics between reactor and hydrogen production system and such a control design concept should be universally applicable to a variety of hydrogen production processes by the use of nuclear heat from HTGR. A transient response analysis of an HTGR-steam reforming hydrogen production system showed that a steam generator installed in a helium circuit for cooling the nuclear reactor provides stable controllability of the total system, resulting in avoiding a reactor scram. A survey of control design-related characteristics among several hydrogen production processes revealed the similarity of endothermic chemical reactions by the use of high temperature heat and that steam is required as a reactant of the endothermic reaction or for preheating a reactant. Based on these findings, a system design concept with stable controllability and universal applicability was proposed to install a steam generator as a downstream cooler of an endothermic reactor in the helium circuit of an HTGR-hydrogen production system.

LARGE PHASE-SPACE OCCUPATION NUMBERS International Nuclear Information System (INIS) Barnes, Eric I.; Williams, Liliya L. R. 2011-01-01 Certain thermal non-equilibrium situations, outside of the astrophysical realm, suggest that entropy production extrema, instead of entropy extrema, are related to stationary states. In an effort to better understand the evolution of collisionless self-gravitating systems, we investigate the role of entropy production and develop expressions for the entropy production rate in two particular statistical families that describe self-gravitating systems. From these entropy production descriptions, we derive the requirements for extremizing the entropy production rate in terms of specific forms for the relaxation function in the Boltzmann equation. We discuss some implications of these relaxation functions and point to future work that will further test this novel thermodynamic viewpoint of collisionless relaxation. 17. Number of papers published in English from the nursing departments of 42 national universities in Japan in the past ten years. Science.gov (United States) Kameoka, Junichi; Iwazaki, Junya; Takahashi, Fumie; Sato, Fumiko; Sato, Kazuki; Taguchi, Atsuko; Nakamura, Yasuka; Ishii, Seiichi; Kagaya, Yutaka 2016-03-01 In Japan, the departments of nursing were established by 2004, and graduate school programs for master's degree were established by 2008, in 42 national universities. With these changes, a more academic mission has been pursued, and the need for writing papers in English has increased. To investigate the numbers of papers published in English from the nursing departments of national universities in Japan over the past ten years. The lists of teachers who have nursing licenses in the departments of nursing in the 42 national universities (n=2292) were obtained from the Japan Association of Nursing Programs in Universities. The number of papers published in English by these teachers from 2004 to 2013 was counted using the SCOPUS database. The average number of total papers, in which at least one of the authors was a nursing teacher, and first-authored papers, in which the first author was a nursing teacher, were 211.4 and 69.9 per year, respectively; both increased approximately two-fold during the past ten years. The means and standard deviations of the number of total papers and first-authored papers were 50.3±63.8 (range: 1-382) and 18.3±23.4 (range: 0-147) according to universities, and 1.39±5.84 (range: 0-140) and 0.33±1.28 (range: 0-21) according to teachers, respectively. When journals with the highest number of papers were analyzed, 12 of the top 20 (total papers) and 12 of the top 16 (first-authored papers) were in journals whose editorial offices are in Japan. The number of papers published in English has increased over the past ten years, varied markedly depending on the universities and teachers, and many papers were published in Japanese journals. To our knowledge, this is the first report anywhere to determine the average number of nursing papers "per teacher" in a specific population. Copyright © 2015 Elsevier Ltd. All rights reserved. 18.

H.; Wysłouch, B.; Phobos Collaboration 2003-04-01 The PHOBOS experiment at RHIC has measured the multiplicity of primary charged particles as a function of centrality and pseudorapidity in Au+Au collisions at √ SNN = 19.6, 130 and 200 GeV. Two kinds of universal behavior are observed in charged particle production in heavy ion collisions. The first is that forward particle production, over a range of energies, follows a universal limiting curve with a non-trivial centrality dependence. The second arises from comparisons with pp/ overlinepp and e +e - data. / in nuclear collisions at high energy scales with √ s in a similar way as Nch in e +e - collisions and has a very weak centrality dependence. This feature may be related to a reduction in the leading particle effect due to the multiple collisions suffered per participant in heavy ion collisions. 19. Genetic parameters for oocyte number and embryo production within a bovine ovum pick-up-in vitro production embryo-production program. Science.gov (United States) Merton, J S; Ask, B; Onkundi, D C; Mullaart, E; Colenbrander, B; Nielen, M 2009-10-15 Genetic factors influencing the outcome of bovine ovum pick-up-in vitro production (OPU-IVP) and its relation to female fertility were investigated. For the first time, genetic parameters were estimated for the number of cumulus-oocyte complexes (Ncoc), quality of cumulus-oocyte complexes (Qcoc), number and proportion of cleaved embryos at Day 4 (Ncleav(D4), Pcleav(D4)), and number and proportion of total and transferable embryos at Day 7 of culture (Nemb(D7), Pemb(D7) and NTemb(D7), PTemb(D7), respectively). Data were recorded by CRV (formally Holland Genetics) from the OPU-IVP program from January 1995 to March 2006. Data were collected from 1508 Holstein female donors, both cows and pregnant virgin heifers, with a total of 18,702 OPU sessions. Data were analyzed with repeated-measure sire models with permanent environment effect using ASREML (Holstein Friesian). Estimates of heritability were 0.25 for Ncoc, 0.09 for Qcoc, 0.19 for Ncleav(D4), 0.21 for Nemb(D7), 0.16 for NTemb(D7), 0.07 for Pcleav(D4), 0.12 for Pemb(D7), and 0.10 for PTemb(D7). Genetic correlation between Ncoc and Qcoc was close to zero, whereas genetic correlations between Ncoc and the number of embryos were positive and moderate to high for Nemb(D7) (0.47), NTemb(D7) (0.52), and Ncleav(D4) (0.85). Genetic correlations between Ncoc and percentages of embryos (Pcleav(D4), Pemb(D7), and PTemb(D7)) were all close to zero. Phenotypic correlations were in line with genetic correlations. Genetic and phenotypic correlations between Qcoc and all other traits were not significant except for the phenotypic correlations between Qcoc and number of embryos, which were negative and low to moderate for Nemb(D7) (-0.20), NTemb(D7) (-0.24), and Ncleav(D4) (-0.43). Results suggest that cumulus-oocyte complex (COC) quality, based on cumulus investment, is independent from the total number of COCs collected via OPU and that in general, a higher number of COCs will lead to a higher number of embryos produced.

Measuring and managing radiologist productivity, part 2: beyond the clinical numbers. Science.gov (United States) Duszak, Richard; Muroff, Lawrence R 2010-07-01 Radiology practices endeavoring to measure physician productivity, identify and motivate performance outliers, and develop equitable management strategies and policies often encounter numerous challenges. Nonetheless, such efforts are often necessary, in both private and academic settings, for a variety of professional, financial, and personnel reasons. Part 1 of this series detailed metrics for evaluating radiologist productivity and reviewed published benchmarks, focusing on clinical work. This segment expands that discussion to evaluating nonclinical administrative and academic efforts, along with professionalism and quality, outlining advantages and disadvantages of addressing differential productivity, and introducing potential models for practices seeking to motivate physicians on the basis of both their clinical and nonclinical endeavors.

Science.gov (United States) Khan, Shah H M; Hedges, William P 2016-04-01 Increasing workloads and the current austerity measures are putting UK radiology departments under considerable stress. We need to look at the most efficient ways to manage radiology departments in order to cope with increasing demand. Consequently, a system is needed that can compare productivity between radiologists with different jobs. We measured workload in a UK radiology department and compared the productivities of consultants working different numbers of sessions, which are called programmed activities (PAs), to identify the optimal job plan structure for reporting productivity. Reporting data was gathered from electronic records for 14 consultants working different numbers of PA during the period April 2010-March 2011. These were converted into relative value unit (RVU) scores using a modified RCSI RVU system. Crude and net workloads were calculated for each consultant by dividing their total RVU score by the number of PAs they were contracted for and how many they spent reporting. The consultants reported 118,001 imaging studies. There was statistically significant variation in productivity between consultants working different numbers of PAs on χ (2) analysis (p working 12 PAs were more productive than consultants working 11 PAs, with net workloads of 7636 RVU/PA/year versus net 6146 RVU/PA/year, p working 12 PAs per week are more productive than their colleagues, the reasons why are unclear. We have identified a method that can be developed further to identify efficient working practices in UK radiology departments. However, a UK-specific RVU system would make this productivity analysis more accurate. 4. How Productive Are Southeastern Wisconsin Schools? Regional Report.

The Effect of Chrysonilia crassa Additive on Duodenal & Caecal Morphology, Bacterial & Fungal Number, and Productivity of Ayam Kampung Directory of Open Access Journals (Sweden) Turrini Yudiarti 2012-10-01 Full Text Available Fungi is a microorganism that can live in gastrointestinal tract of chicken. One type of fungi is multicellular or filamentous fungi. C.crassa is a species of filamentous fungi that has been isolated in the earlier study and it showed the best probiotic potency in vitro. The obyective of this research was to study the effect of addition of dried culture of C.crassa in feed on intestinal & caecal morphology, bacterial & fungal number, and productivity of indigenous chicken (ayam kampung. Research used completely randomized design with four treatments. The treatments were the level of dried culture in basal diet (0%, 0.25 %, 0.50 % and 0.75 %. Each treatment was replicated 5 times and each replicate consists of 10 chickens. The parameters observed were : villi morphology, number of bacteria and fungi in the duodenum and cecum of chickens aged 1, 21 and 35 days and productivity i.e. feed intake, final body weight and feed conversion. The results showed that 0.50% dried culture of C.crassa could increase the duodenal villi width, decreased the number of bacterial and fungal colonies in duodenum and caecum, but it did not increase productivity. The conclusion : C.crassa could stimulate the duodenal villi development and decreased the number of the bacteria and fungi in the gastrointestinal tract, yet it has no positive impact on the chicken productivity. 7.

Tailoring the Glasgow University diagnostic aid for the product storage facilities at TRP Energy Technology Data Exchange (ETDEWEB) Howell, J.; Miller, E 2001-02-01 This report concludes the work carried out under Task D2(d)/UK D00912: Development of Anomaly Diagnosis Algorithms for a Plutonium Tank Monitoring System, which was the companion to Task D2(c)/UK D00913: Analysis and Diagnosis of Anomalies at Bulk-Handling Nuclear Materials Facilities: Benchmarking and Optimisation. Between them these tasks produced a computer software package that could diagnose anomalies in plant data pertaining to solutions of nuclear materials stored and transported around reprocessing plants. The final goal of Task UK D00912 was to demonstrate to the Agency that the software could be applied to the product storage area at the Tokai Reprocessing Plant in Japan. The University of Glasgow does not produce software to any recognisable standard, so this was not an acceptance trial, but a demonstration. It was recognised that further software development would be required before the package could be accepted as a safeguards tool. Being the final report, the report focuses on the issues that are still outstanding so those who choose to continue with this work have a clear understanding of the status of the software. It is taken for granted that the reader appreciates that the package should be able to explain relatively small anomalies (> 0.1 SQ) and has numerous features to estimate evaporation rates, pipe hold-up and so on. Here the focus is on the minor gremlins that are still to be resolved. The report first explains how the software package would be tailored so that it could be implemented at TRP. Of key importance is the fact that the plant uses scanivalves, which multiplex pressure lines from various dip-tubes onto the same pressure transducer. Although suitable for the measurement of a number of signals that are always steady, these devices are less suited to situations where tanks are frequently sparged and where the anomalies of interest inherently relate to changes in data and hence to non-steady operation.

If the parameters in the${\\rlap/R}_p$supersymmetric interactions are not too small, and the mass of gluino is considered in the range from several GeV (as the Lightest Supersymmetric Particle) to 800 GeV, the cross section of the single gluino production via Drell-Yan processes can be in the order of$10^2 \\sim 10^3$femto barn, and that via gluon fusion in the order of$10^{-1} \\sim 10^3$femto barn. If the gluino decay can be well detected in the CERN LHC, this process provides a prospective way to probe supersymmetry and$R_pviolation. 10. Study of an investigation on factors influencing human resources productivity in Shiraz University of Medical Sciences Directory of Open Access Journals (Sweden) Zahra Ghasemi 2016-01-01 Full Text Available Introduction: Human resources development is one of the most important components of any organization and detecting important factors influencing human resources management plays an essential role in the success of the firms. In this study, we investigated different factors influencing human resources productivity of Shiraz University of Medical Sciences staff. Method: The present research was a cross-sectional study. Sample size was calculated 208 individuals. To access information about the human resource productivity, a valid and reliable questionnaire was used. The data were analyzed using SPSS software. Pearson correlation was used for statistical analysis of the data (p=0.05. Results:The results showed that there was a statistically significant relationship (p-value<0.001 between human resources productivity and factors affecting the productivity of human resources (motivational factors, leadership style, creativity and innovation, general and applied education, and competitive spirit. Motivational factors (r =0.89 and general education (r =0.65 had the most and the least effects on human resources productivity. Conclusion: Considering the fact that motivational factors were the most effective factors on human resource productivity, we recommend that managers should care more than before about this factor; also, in order to motivate the employees, they should consider the staff’s individual differences. 11. FOX: A Fault-Oblivious Extreme-Scale Execution Environment Boston University Final Report Project Number: DE-SC0005365 Energy Technology Data Exchange (ETDEWEB) Appavoo, Jonathan [Boston Univ., MA (United States) 2013-03-17 Exascale computing systems will provide a thousand-fold increase in parallelism and a proportional increase in failure rate relative to today's machines. Systems software for exascale machines must provide the infrastructure to support existing applications while simultaneously enabling efficient execution of new programming models that naturally express dynamic, adaptive, irregular computation; coupled simulations; and massive data analysis in a highly unreliable hardware environment with billions of threads of execution. The FOX project explored systems software and runtime support for a new approach to the data and work distribution for fault oblivious application execution. Our major OS work at Boston University focused on developing a new light-weight operating systems model that provides an appropriate context for both multi-core and multi-node application development. This work is discussed in section 1. Early on in the FOX project BU developed infrastructure for prototyping dynamic HPC environments in which the sets of nodes that an application is run on can be dynamically grown or shrunk. This work was an extension of the Kittyhawk project and is discussed in section 2. Section 3 documents the publications and software repositories that we have produced. To put our work in context of the complete FOX project contribution we include in section 4 an extended version of a paper that documents the complete work of the FOX team. 12. Institutional Restrictions on Scientific Productivity: The Case Study of a Mexican Public University Directory of Open Access Journals (Sweden) Ana Isabel Metlich Medlich 2009-05-01 Full Text Available Identifying factors which restrict research is not only important for universities but for their professors. In this paper different aspects are researched and identified, which may influence scientific productivity. As a basis for this paper 48 interviews were conducted with researchers from a State Public University. These researchers were chosen including those from the highest level in the National System of Researchers (of Mexico, SNI for its acronym in Spanish Sistema Nacional de Investigadores, to those who have not yet entered it. The results sustain that professors have been submitted to requirements that hinder the development of their multiple tasks, among those stand out: produce knowledge, teach, and tutor students, follow internal and surrounding policies. 13. The metrological assurance of quality petroleum products. Methods for determining octane and sulfur numbers in the petroleum products Science.gov (United States) Shalkov, A. V.; Fadeev, Y. A. 2018-01-01 At present, solving environmental problems in industrially developed regions with a large concentration of mining and machine building enterprises is one of the main socially important tasks. Taking into account the increase in the volume of mining, there is an increase in the environmental burden, which affects the internal migration of the population. This is particularly evident in the examples of single-industry towns, in which a gradual decrease in the young workable population occurs. The article presents an analysis of the sources of maximum pollution of the environment by coal mining enterprises. Modern methods of controlling automobile fuel were analyzed. The analysis of fuel quality and the environmental assessment of combustion products was carried out. The equipment used in the article makes it possible to exclude substandard fuel and to reduce harmful emissions of vehicles to the atmosphere. 14. Analysis of university student awareness of radiation exposures from consumer products Energy Technology Data Exchange (ETDEWEB) Kim, Seung Hwan [Korean Advance Institute of Science and Technology, Daejeon (Korea, Republic of); Cho, Kun Woo [Korea Institute of Nuclear Safety, Daejeon (Korea, Republic of) 2016-05-15 Since the terminology 'radioactive consumer product' is not quite familiar to the public and is often considered as negative and detrimental things, the educational curriculum is essential for establishing reliability of nuclear energy related and for the development of better communication strategy of radiation risk with the public. To provide base data which is valuable for establishing efficient curriculum of education and training about radiation safety, it is necessary to apprehend the different level of awareness of radiation exposures classified by various consumer products. On November 2014, a question investigation about asking awareness level of radiation exposure from various consumer products was done for university students who are highly educated. The object students are studied at a four-year-course universities which is located at Daejeon City. Although the average awareness level is comparatively low, the awareness of senior students, who major in radiation, nuclear related departments and male students are relatively high. On the other hand, the awareness of freshman, sophomore, junior students, who do not major in radiation, nuclear related departments and female students are relatively low. It is necessary to provide various information to avoid unnecessary concerns and misconceptions about radiation exposure. This paper will be an instrument for efficient establishment of curriculum of education and training related with radiation safety. 15.

A method for conversion of Hounsfield number to electron density and prediction of macroscopic pair production cross-sections International Nuclear Information System (INIS) Knoeoes, T.; Nilsson, M.; Ahlgren, L. 1986-01-01 A method for the determination of electron density using a narrow beam attenuation geometry is described. The method does not require that the elemental composition of the phantom materials is known. The Hounsfield numbers for the phantom materials used were determined using five different CT scanners. A relationship between Hounsfield number and electron density can thus be established, which is of considerable value in radiation therapy treatment planning procedures. Measurements of the ratio coherent/incoherent scattering of low energy photons in a certain geometry has proven valuable for determination of atomic number, which in its turn can be used for estimation of macroscopic pair production coefficients for high energy photons. The combination of knowledge of electron density with methods for determination of processes, dependent on atomic number, can form a base for adequate composition of phantom materials for purposes of testing dose calculation algorithms for photons and electrons.

Science.gov (United States) Reinheimer, M Agustina; Scenna, Nicolás J; Mussati, Sergio F 2016-12-01 Water consumption required during the leaching stage in the surimi manufacturing process strongly depends on the design and the number and size of stages connected in series for the soluble protein extraction target, and it is considered as the main contributor to the operating costs. Therefore, the optimal synthesis and design of the leaching stage is essential to minimize the total annual cost. In this study, a mathematical optimization model for the optimal design of the leaching operation is presented. Precisely, a detailed Mixed Integer Nonlinear Programming (MINLP) model including operating and geometric constraints was developed based on our previous optimization model (NLP model). Aspects about quality, water consumption and main operating parameters were considered. The minimization of total annual costs, which considered a trade-off between investment and operating costs, led to an optimal solution with lesser number of stages (2 instead of 3 stages) and higher volumes of the leaching tanks comparing with previous results. An analysis was performed in order to investigate how the optimal solution was influenced by the variations of the unitary cost of fresh water, waste treatment and capital investment. 18. Influence of milking number and frequency on milk production in Martina Franca breed asses Directory of Open Access Journals (Sweden) G. Martemucci 2010-04-01 Full Text Available Two experiments were carried out in Martina Franca asses in order to study milk yield and udder healthy conditions in relation to daily milking number and frequency. Experiment I - A total of 15 asses were subdivided into three groups (N.5 corresponding to: one milking per day, after a 3 hour interval from foal separation by dams (Group A; three milkings per day with 3 hour frequency (Group B; three milkings per day with 2 hour frequency (Group 3M. Experiment II - Evaluation was made of the effect of a schedule of 6 milkings per day with frequency of 2 hours on milk yield (Group 6M; N. 5, compared to Group 3M. Healthy udder conditions in relation to the number of milking per day was monitored in 3M and 6M Groups, by somatic cell count. Average yield per milking was highest (P<0.01 following 3 rather 1 milkings per day and with milking frequency of 3 hours rather than 2 hours (P<0.01. A schedule of six milkings per day did not improve mean milk yield and determined an increase in somatic cell count compared to 3 daily milkings regimen (63.2 vs 17.5 x 1000/mL; P<0.05. 19. Efficiency of Human Epiphyseal Chondrocytes with Differential Replication Numbers for Cellular Therapy Products Directory of Open Access Journals (Sweden) Michiyo Nasu 2016-01-01 Full Text Available The cell-based therapy for cartilage or bone requires a large number of cells; serial passages of chondrocytes are, therefore, needed. However, fates of expanded chondrocytes from extra fingers remain unclarified. The chondrocytes from human epiphyses morphologically changed from small polygonal cells to bipolar elongated spindle cells and to large polygonal cells with degeneration at early passages. Gene of type II collagen was expressed in the cells only at a primary culture (Passage 0 and Passage 1 (P1 cells. The nodules by implantation of P0 to P8 cells were composed of cartilage and perichondrium. The cartilage consisted of chondrocytes with round nuclei and type II collagen-positive matrix, and the perichondrium consisted of spindle cells with type I collage-positive matrix. The cartilage and perichondrium developed to bone with marrow cavity through enchondral ossification. Chondrogenesis and osteogenesis by epiphyseal chondrocytes depended on replication number in culture. It is noteworthy to take population doubling level in correlation with pharmaceutical efficacy into consideration when we use chondrocytes for cell-based therapies. 20. Product-selective blot: a technique for measuring enzyme activities in large numbers of samples and in native electrophoresis gels International Nuclear Information System (INIS) Thompson, G.A.; Davies, H.M.; McDonald, N. 1985-01-01 A method termed product-selective blotting has been developed for screening large numbers of samples for enzyme activity. The technique is particularly well suited to detection of enzymes in native electrophoresis gels. The principle of the method was demonstrated by blotting samples from glutaminase or glutamate synthase reactions into an agarose gel embedded with ion-exchange resin under conditions favoring binding of product (glutamate) over substrates and other substances in the reaction mixture. After washes to remove these unbound substances, the product was measured using either fluorometric staining or radiometric techniques. Glutaminase activity in native electrophoresis gels was visualized by a related procedure in which substrates and products from reactions run in the electrophoresis gel were blotted directly into a resin-containing image gel. Considering the selective-binding materials available for use in the image gel, along with the possible detection systems, this method has potentially broad application 1.

Single-top-squark production via baryon-number-violating couplings at the Fermilab Tevatron Collider International Nuclear Information System (INIS) Berger, E. L.; Harris, B. W.; Sullivan, Z. 1999-01-01 We consider the s-channel R-parity-violating production of a single light top squark tilde t 1 and its subsequent R-parity-conserving decay. For masses in the range 180-325 GeV, and R-parity-violating couplings λ 3ij double p rime > 0.02-0.05, we show that discovery of the top squark is possible with 2 fb -1 of integrated luminosity at run II. If no evidence for the top squark is found, the bound on λ 3ij '' can be reduced by up to an order of magnitude with existing data from run I, and by two orders of magnitude at run II 3. Effect of lipopolysaccharide (LPS and peptidoglycan (PGN on human mast cell numbers, cytokine production, and protease composition Directory of Open Access Journals (Sweden) Wu Yalin 2008-08-01 Full Text Available Abstract Background Human mast cell (HuMC maturation occurs in tissues interfacing with the external environment, exposing both mast cell progenitors and mature mast cells, to bacteria and their products. It is unknown, however, whether long- or short-term exposure to bacteria-derived toll-like receptor (TLR ligands, such as lipopolysaccharide (LPS or peptidoglycan (PGN, influences HuMC biology. Results Over 6 wks of culture, LPS had minimal effect on HuMC numbers but increased CD117, tryptase and chymase expression. PGN inhibited HuMC development. For mature mast cells, LPS in the presence of rhSCF (10 ng/ml increased CD117, tryptase, chymase and carboxypeptidase expression, primarily in CD117low HuMC. LPS decreased FcεRI expression and β-hexosaminidase release; but had no effect on LTC4 and PGD2 production. PGN reduced HuMC numbers; and CD117 and tryptase expression. IL-1β and IL-6 (in addition to IL-8 and IL-12 were detected in short-term culture supernatants of LPS treated cells, and reproduced the increases in CD117, tryptase, chymase, and carboxypeptidase expression observed in the presence of LPS. Comparative studies with mouse bone marrow-derived mast cells from wild type, but not TLR4 knockout mice, showed increases in mRNA of mouse mast cell chymases MMCP-1, MMCP-2 and MMCP-4. Conclusion PGN inhibits HuMC growth, while LPS exerts its primary effects on mature HuMC by altering cytokine production and protease composition, particularly at low concentrations of SCF. These data demonstrate the ability of bacterial products to alter HuMC mediator production, granular content, and number which may be particularly relevant at mucosal sites where HuMC are exposed to these products. 4. Atomic Number Dependence of Hadron Production at Large Transverse Momentum in 300 GeV Proton--Nucleus Collisions Science.gov (United States) Cronin, J. W.; Frisch, H. J.; Shochet, M. J.; Boymond, J. P.; Mermod, R.; Piroue, P. A.; Sumner, R. L. 1974-07-15 In an experiment at the Fermi National Accelerator Laboratory we have compared the production of large transverse momentum hadrons from targets of W, Ti, and Be bombarded by 300 GeV protons. The hadron yields were measured at 90 degrees in the proton-nucleon c.m. system with a magnetic spectrometer equipped with 2 Cerenkov counters and a hadron calorimeter. The production cross-sections have a dependence on the atomic number A that grows with P{sub 1}, eventually leveling off proportional to A{sup 1.1}. 5. Effects of Comprehension and Production-Based Tasks on Learning Morphosyntax by University EFL Students Directory of Open Access Journals (Sweden) Nasser Gardaoui 2016-06-01 Full Text Available This article presents the results of an experimental study investigating the differential effects of two grammar-teaching options on learning tense and grammatical aspect. The treatment conditions were implemented with young adult Algerian EFL learners in two first-semester classes at the university level.The first group was given comprehension practice only. The second group was given both comprehension and production practice.Descriptive statistics indicated that the second group outperformed the first group. However, the statistical analysis (Anova revealed that the instructional effect did not amount to statistically significant learning gains. Pedagogically, the results of the study seem to support the use of output practice as well as input-based practice in the classroom. It is necessary to carry out research on other aspects of language in other similar contexts in order to know which activities of comprehension or production are most effective. 6. Improving technology universal vegetable semi-finished products for the enterprises of food industry Directory of Open Access Journals (Sweden) M. N. Kutkina 2016-01-01 Full Text Available Healthy nutrition is one of the main factors that becomes stronger the human immune system, especially in the big cities, forms intellectual abilities of people, increases the qualitative characteristics of living standards etc. The most important components of a healthy nutrition are vegetables and products from them. Rather high moisture content of many vegetables, e.g., fruit, partially fills the needs of the human organism in water, lowers the energy value of the diet, enhances the motility of the gastrointestinal tract. In this regard, the improvement of technology universal product from regional vegetables available has got importance, prolonged pronounced social effect and contributes to health improvement. Among vegetables the zucchini include diet properties, but the use of them is accompanied by certain difficulties associated with seasonal logistics and the limited range of products from them. In this work, there were studied the varietal characteristics of the zucchini, zoned in the North-West region, in terms of their technological properties, morphological characteristics and biochemical composition of fruit during ripening. Were investigated the optimal ways of canning zucchini by drying with freeze-drying and infrared heating that allows you to provide catering universal semi-finished product during the whole year, not only in areas of cultivation, but also in areas outside of growing vegetables. There was discovered the effect of anomalous dehydration of fruit vegetables in the result of the study , which helped to explain the increased, in comparison with other types of vegetables, losses during heat treatment and to justify their methods and technological parameters of drying. It was found that one of the reasons for the reduction of mechanical strength parenchymal tissue of fruit vegetables, is the destruction of cell walls by increasing the pressure inside the air inclusions, in contrast to some other types of fruit 7. Determining the optimal number of Kanban in multi-products supply chain system Science.gov (United States) Widyadana, G. A.; Wee, H. M.; Chang, Jer-Yuan 2010-02-01 Kanban, a key element of just-in-time system, is a re-order card or signboard giving instruction or triggering the pull system to manufacture or supply a component based on actual usage of material. There are two types of Kanban: production Kanban and withdrawal Kanban. This study uses optimal and meta-heuristic methods to determine the Kanban quantity and withdrawal lot sizes in a supply chain system. Although the mix integer programming method gives an optimal solution, it is not time efficient. For this reason, the meta-heuristic methods are suggested. In this study, a genetic algorithm (GA) and a hybrid of genetic algorithm and simulated annealing (GASA) are used. The study compares the performance of GA and GASA with that of the optimal method using MIP. The given problems show that both GA and GASA result in a near optimal solution, and they outdo the optimal method in term of run time. In addition, the GASA heuristic method gives a better performance than the GA heuristic method. 8. Are products sold in university vending machines nutritionally poor? A food environment audit. Science.gov (United States) Grech, Amanda; Hebden, Lana; Roy, Rajshri; Allman-Farinelli, Margaret 2017-04-01 (i) To audit the nutritional composition, promotion and cost of products available from vending machines available to young adults; and (ii) to examine the relationship between product availability and sales. A cross-sectional analysis of snacks and beverages available and purchased at a large urban university was conducted between March and September 2014. Sales were electronically tracked for nine months. A total of 61 vending machines were identified; 95% (n = 864) of the available snacks and 49% of beverages (n = 455) were less-healthy items. The mean (SD) nutrient value of snacks sold was: energy 1173 kJ (437.5), saturated fat 5.36 g (3.6), sodium 251 mg (219), fibre 1.56 g (1.29) and energy density 20.16 kJ/g (2.34) per portion vended. There was a strong correlation between the availability of food and beverages and purchases (R 2 = 0.98, P Vending machines market and sell less-healthy food and beverages to university students. Efforts to improve the nutritional quality are indicated and afford an opportunity to improve the diet quality of young adults, a group at risk of obesity. © 2016 Dietitians Association of Australia. 9. Scientific Production of Research Fellows at the Zagreb University School of Medicine, Croatia Science.gov (United States) Polašek, Ozren; Kolčić, Ivana; Buneta, Zoran; Čikeš, Nada; Pećina, Marko 2006-01-01 Aim To evaluate scientific production among research fellows employed at the Zagreb University School of Medicine and identify factors associated with their scientific output. Method We conducted a survey among research fellows and their mentors during June 2005. The main outcome measure was publication success, defined for each fellow as publishing at least 0.5 articles per employment year in journals indexed in the Current Contents bibliographic database. Bivariate methods and binary logistic regression were used in data analysis. Results A total of 117 fellows (response rate 95%) and 83 mentors (100%) were surveyed. The highest scientific production was recorded among research fellows employed in public health departments (median 3.0 articles, interquartile range 4.0), compared with those from pre-clinical (median 0.0, interquartile range 2.0) and clinical departments (median 1.0, interquartile range 2.0) (Kruskal-Wallis, P = 0.003). A total of 36 (29%) research fellows published at least 0.5 articles per employment year and were considered successful. Three variables were associated with fellows’ publication success: mentor’s scientific production (odds ratio [OR], 3.14; 95% confidence interval [CI], 1.31-7.53), positive mentor’s assessment (OR, 3.15; 95% CI, 1.10-9.05), and fellows’ undergraduate publication in journals indexed in the Current Contents bibliographic database (OR, 4.05; 95% CI, 1.07-15.34). Conclusion Undergraduate publication could be used as one of the main criteria in selecting research fellows. One of the crucial factors in a fellow’s scientific production and career advancement is mentor’s input, which is why research fellows would benefit most from working with scientifically productive mentors.

Universal Generating Function Based Probabilistic Production Simulation Approach Considering Wind Speed Correlation Directory of Open Access Journals (Sweden) Yan Li 2017-11-01 Full Text Available Due to the volatile and correlated nature of wind speed, a high share of wind power penetration poses challenges to power system production simulation. Existing power system probabilistic production simulation approaches are in short of considering the time-varying characteristics of wind power and load, as well as the correlation between wind speeds at the same time, which brings about some problems in planning and analysis for the power system with high wind power penetration. Based on universal generating function (UGF, this paper proposes a novel probabilistic production simulation approach considering wind speed correlation. UGF is utilized to develop the chronological models of wind power that characterizes wind speed correlation simultaneously, as well as the chronological models of conventional generation sources and load. The supply and demand are matched chronologically to not only obtain generation schedules, but also reliability indices both at each simulation interval and the whole period. The proposed approach has been tested on the improved IEEE-RTS 79 test system and is compared with the Monte Carlo approach and the sequence operation theory approach. The results verified the proposed approach with the merits of computation simplicity and accuracy. 11. The Opportunities Map at Cornell University: finding direction in dairy production medicine. Science.gov (United States) Mitchell, Hilda M; Nydam, Daryl V; Reyher, Kristen; Gilbert, Robert O 2004-01-01 Discussion between faculty and interested students revealed the existence of a multitude of opportunities in dairy production medicine at the College of Veterinary Medicine at Cornell University. Many of these were not well known to students, or even to some of the faculty, and the means of accessing specific learning experiences were sometimes obscure. Together, an informal group of faculty, students, and alumni set about cataloging available educational opportunities, resulting in a 31-page publication referred to as the "Opportunities Map." Essentially a student handbook for production medicine students, the Opportunities Map at Cornell helps guide the travel of food animal-interested students through the curriculum without missing the important highlights along the way. The map was originally developed to chronicle the opportunities and resources available to students, but it has also been used to foster face-to-face communications between students and faculty, to welcome incoming students with production animal interests, and to provide a baseline description for further discussion about the curriculum. 12. Integrating medical, assistive, and universally designed products and technologies: assistive technology device classification (ATDC). Science.gov (United States) Bauer, Stephen; Elsaesser, Linda-Jeanne 2012-09-01 ISO26000:2010 International Guidance Standard on Organizational Social Responsibility requires that effective organizational performance recognize social responsibility, including the rights of persons with disabilities (PWD), engage stakeholders and contribute to sustainable development. Millennium Development Goals 2010 notes that the most vulnerable people require special attention, while the World Report on Disability 2011 identifies improved data collection and removal of barriers to rehabilitation as the means to empower PWD. The Assistive Technology Device Classification (ATDC), Assistive Technology Service Method (ATSM) and Matching Person and Technology models provide an evidence-based, standardized, internationally comparable framework to improve data collection and rehabilitation interventions. The ATDC and ATSM encompass and support universal design (UD) principles, and use the language and concepts of the International Classification of Functioning, Disability and Health (ICF). Use ATDC and ICF concepts to differentiate medical, assistive and UD products and technology; relate technology "types" to markets and costs; and support provision of UD products and technologies as sustainable and socially responsible behavior. Supply-side and demand-side incentives are suggested to foster private sector development and commercialization of UD products and technologies. Health and health-related professionals should be knowledgeable of UD principles and interventions. 13. An analysis of psychotropic drug sales. Increasing sales of selective serotonin reuptake inhibitors are closely related to number of products. Science.gov (United States) Nielsen, Margrethe; Gøtzsche, Peter 2011-01-01 Prescribing of selective serotonin reuptake inhibitors (SSRIs) has increased dramatically. To compare the sales of benzodiazepines and SSRIs within the primary care sector in Denmark and relate changes in usage to number of indications and products on the market. We used data from various sources to establish the sales curves of psychotropic drugs in the period 1970 to 2007, based on the Anatomic Therapeutic Classification system and Defined Daily Doses. Fluctuations in sales of psychotropic drugs that cannot be explained by disease prevalence were caused by changes in sales of the benzodiazepines and SSRIs. We found a decline in the sales of benzodiazepines after a peak in 1986, likely due to the recognition that they cause dependence. From a low level in 1992, we found that the sales of SSRIs increased almost linearly by a factor of 18, up to 44 DDD per 1000 inhabitants, which was closely related to the number of products on the market that increased by a factor of 16. Sales of antidepressant drugs are mainly determined by market availability of products indicating that marketing pressures are playing an important role. Thus the current level of use of SSRIs may not be evidence-based, which is supported by studies showing that the effect of SSRIs has been overestimated. 14. Maillard reaction products from highly heated food prevent mast cell number increase and inflammation in a mouse model of colitis. Science.gov (United States) Al Amir, Issam; Dubayle, David; Héron, Anne; Delayre-Orthez, Carine; Anton, Pauline M 2017-12-01 Links between food and inflammatory bowel diseases (IBDs) are often suggested, but the role of food processing has not been extensively studied. Heat treatment is known to cause the loss of nutrients and the appearance of neoformed compounds such as Maillard reaction products. Their involvement in gut inflammation is equivocal, as some may have proinflammatory effects, whereas other seem to be protective. As IBDs are associated with the recruitment of immune cells, including mast cells, we raised the hypothesis that dietary Maillard reaction products generated through heat treatment of food may limit the colitic response and its associated recruitment of mast cells. An experimental model of colitis was used in mice submitted to mildly and highly heated rodent food. Adult male mice were divided in 3 groups and received nonheated, mildly heated, or highly heated chow during 21 days. In the last week of the study, each group was split into 2 subgroups, submitted or not (controls) to dextran sulfate sodium (DSS) colitis. Weight variations, macroscopic lesions, colonic myeloperoxidase activity, and mucosal mast cell number were evaluated at the end of the experiment. Only highly heated chow significantly prevented DSS-induced weight loss, myeloperoxidase activity, and mast cell number increase in the colonic mucosa of DSS-colitic mice. We suggest that Maillard reaction products from highly heated food may limit the occurrence of inflammatory phases in IBD patients. Copyright © 2017 Elsevier Inc. All rights reserved. 15. Cross-cultural and cross-ecotype production of a killer whale excitement' call suggests universality Science.gov (United States) Rehn, Nicola; Filatova, Olga A.; Durban, John W.; Foote, Andrew D. 2011-01-01 Facial and vocal expressions of emotion have been found in a number of social mammal species and are thought to have evolved to aid social communication. There has been much debate about whether such signals are culturally inherited or are truly biologically innate. Evidence for the innateness of such signals can come from cross-cultural studies. Previous studies have identified a vocalisation (the V4 or excitement' call) associated with high arousal behaviours in a population of killer whales in British Columbia, Canada. In this study, we compared recordings from three different socially and reproductively isolated ecotypes of killer whales, including five vocal clans of one ecotype, each clan having discrete culturally transmitted vocal traditions. The V4 call was found in recordings of each ecotype and each vocal clan. Nine independent observers reproduced our classification of the V4 call from each population with high inter-observer agreement. Our results suggest the V4 call may be universal in Pacific killer whale populations and that transmission of this call is independent of cultural tradition or ecotype. We argue that such universality is more consistent with an innate vocalisation than one acquired through social learning and may be linked to its apparent function of motivational expression. 16. Four-dimensional jets of hadrons: universal characteristics of multiple production of particles International Nuclear Information System (INIS) Baldin, A.M.; Batyunya, B.V.; Gramenitskii, I.M.; Grishin, V.G.; Didenko, L.A.; Kuznetsov, A.A.; Metreveli, Z.V. 1986-01-01 In a new relativistically invariant approach, data on multiple production of particles are analyzed in pp, p-barp, π - p, π - C, pC, and pTa interactions in the momentum range from 6 to 205 GeV/c. Distributions of hadrons (π - , K 0 /sub S/, Λ) in the square of the 4-velocity (b/sub k/) relative to the jet axis are obtained. It is shown that at a momentum p/sub lab/ ≥22 GeV/c these distributions do not depend on energy and are identical for hadronization of quarks and of multiquark systems. The observed universal properties of 4-dimensional jets of hadrons apparently are fundamental characteristics of interactions of color charges with the vacuum 17.

Dark Matter Freeze-in Production in Fast-Expanding Universes Science.gov (United States) D'Eramo, Francesco; Fernandez, Nicolas; Profumo, Stefano 2018-02-01 If the dark matter is produced in the early universe prior to Big Bang nucleosynthesis, a modified cosmological history can drastically affect the abundance of relic dark matter particles. Here, we assume that an additional species to radiation dominates at early times, causing the expansion rate at a given temperature to be larger than in the standard radiation-dominated case. We demonstrate that, if this is the case, dark matter production via freeze-in (a scenario when dark matter interacts very weakly, and is dumped in the early universe out of equilibrium by decay or scattering processes involving particles in the thermal bath) is dramatically suppressed. We illustrate and quantitatively and analytically study this phenomenon for three different paradigmatic classes of freeze-in scenarios. For the frozen-in dark matter abundance to be as large as observations, couplings between the dark matter and visible-sector particles must be enhanced by several orders of magnitude. This sheds some optimistic prospects for the otherwise dire experimental and observational outlook of detecting dark matter produced by freeze-in. 1. Serial number coding and decoding by laser interference direct patterning on the original product surface for anti-counterfeiting. Science.gov (United States) Park, In-Yong; Ahn, Sanghoon; Kim, Youngduk; Bae, Han-Sung; Kang, Hee-Shin; Yoo, Jason; Noh, Jiwhan 2017-06-26 Here, we investigate a method to distinguish the counterfeits by patterning multiple reflective type grating directly on the surface of the original product and analyze the serial number from its rotation angles of diffracted fringes. The micro-sized gratings were fabricated on the surface of the material at high speeds by illuminating the interference fringe generated by passing a high-energy pulse laser through the Fresnel biprism. In addition, analysis of the grating's diffraction fringes was performed using a continuous wave laser. 2.

Obstacles of Academic Productivity of Faculty Members in the Education College at Jeddah University as Perceived by them Directory of Open Access Journals (Sweden) Fahad Abdulrahamn Almalki 2017-12-01 Full Text Available The purpose of the study was to investigate the obstacles of academic productivity of faculty members in the education college at Jeddah University as perceived by them. The study adopted the descriptive analytical approach by using a questionnaire to collect data. The researcher developed the questionnaire which consisted of (46 items and were distributed over four themes. The questionnaire was checked for its validity and reliability. Then, it was administrated to a sample of (80 faculty members in the education faculty at Jeddah University. The findings of the study were as follows: The effect of university and society obstacles on academic productivity was given a high rate. On the other hand, the effect of personal obstacles and academic publication received an average rate. The society obstacles were ranked first, while academic publication obstacles were in the last rank. There were statistically significant differences which were attributed to the differences in academic rank in the obstacles related to university, society and personal and academic publication in favor of the assistant professor rank. There were also statistically significant differences that were attributed to years of experience in university obstacles in favor of (1-5 years experience and (more than 10 years experience. On the other hand, there were no differences in university, society and personal obstacles. There were no statistically significant differences attributed to the variable of the university from which the faculty members got their PhD degree. In addition, there were statistically significant differences attributed to nationality in university, personal and society obstacles while there were no differences in the variable of academic publication. The study recommended the need to increase funds to be allocated for academic productivity. Keywords: Academic productivity, Faculty members, Obstacles, Universities. 4. Consumer Attitudes Toward Advertisement and Brand, Based on the Number of Endorsers and Product Involvement: An Experimental Study Directory of Open Access Journals (Sweden) Tanti Handriana 2017-12-01 Full Text Available Utilizing endorsers in the advertising industry to promote products is currently on the rise, and employing celebrities as the endorsers is still the marketers’ favorite method. This study aims to analyze the influence of the number of endorsers and the product’s involvement on the consumers’ attitude towards the advertisement and the brand. The research’s approach used a 2x2 factorial experimental design. A total of 120 undergraduate students, who were further divided into 4 groups, were selected as the respondents of this study. The results show the differences in consumer attitudes towards advertisements and the brand, based on the number of endorsers and the product’s involvement. The study also reveals that if there is low involvement with the product, multiple celebrity endorsements will generate a better consumers’ attitude towards it than a single celebrity endorsement. Multiple celebrity endorsements will also generate a better attitude among the consumers towards the brand than a single celebrity endorsement will produce. 5. THE ANALYSIS OF SONG-TEXT COLLECTION BELONGS TO THE SIXTEENTH CENTURY: Bodleian Library of Oxford University With The Number of 127 and 128 Directory of Open Access Journals (Sweden) Mehmet Nuri Parmaksiz 2016-09-01 Full Text Available The song-text collections have great significance in consequence of their tasks in Turkish Music.

Leydig cell number and sperm production decrease induced by chronic ametryn exposure: a negative impact on animal reproductive health. Science.gov (United States) Dantas, T A; Cancian, G; Neodini, D N R; Mano, D R S; Capucho, C; Predes, F S; Pulz, R Barbieri; Pigoso, A A; Dolder, H; Severi-Aguiar, G D C 2015-06-01 Ametryn is an herbicide used to control broadleaf and grass weeds and its acute and chronic toxicity is expected to be low. Since toxicological data on ametryn is scarce, the aim of this study was to evaluate rat reproductive toxicity. Thirty-six adult male Wistar rats (90 days) were divided into three groups: Co (control) and T1 and T2 exposed to 15 and 30 mg/kg/day of ametryn, respectively, for 56 days. Testicular analysis demonstrated that ametryn decreased sperm number per testis, daily sperm production, and Leydig cell number in both treated groups, although little perceptible morphological change has been observed in seminiferous tubule structure. Lipid peroxidation was higher in group T2, catalase activity decreased in T1 group, superoxide dismutase activity diminished, and a smaller number of sulphydryl groups of total proteins were verified in both exposed groups, suggesting oxidative stress. These results showed negative ametryn influence on the testes and can compromise animal reproductive performance and survival. 7. Production of Astatine-211 at the Duke University Medical Center for its regional distribution Energy Technology Data Exchange (ETDEWEB) Zalutsky, Michael [Duke University Medical Center, Durham, NC (United States) 2016-01-01 Systemic targeted radiation therapy and radioimmunotherapy continue to be important tools in the treatment of certain cancers. Because of their high energy and short path length, alpha particle emitters such as 211At are more effective than either external beam x- ray or in vivo beta radiation in delivering potentially curative doses of radiation. The limited clinical trials that have been conducted to date have yielded encouraging responses in some patients, e.g., malignant brain tumors. In order to escalate the additional necessary research and development in radiochemistry, radiobiology and efficacy evaluation of alpha particle radiotherapeutics, it is universally agreed that access to an affordable, reliable supply of 211At is warranted. In conjunction with the Department of Energy's intent to enhance stable and radioactive isotope availability for research applications, it is the primary objective of this project to improve 211At production and purification capabilities at Duke so that this radionuclide can be supplied to researchers at other institutions throughout the US.The most widely used 211At production method involves the α,2n reaction on Bismuth using a cyclotron with beams ≤ 28 MeV. Yields can be enhanced with use of an internal target that allows for a higher alpha fluence plus efficient heat dissipation in the target. Both of these items are in place at Duke; however, in order to support production for multi-institutional use, irradiation campaigns in excess of 50 µAp and four hours duration will be needed. Further, post-irradiation processing equipment is lacking that will enable the distribution process. Financial support is sought for i) a shielded, ventilated processing/containment hood; ii) development of a post-irradiation target retrieval system; iii) fabrication of a 211At distillation and recovery module and iv) a performance review and, where needed, an enhancement of seven 8. Dairy sheep production research at the University of Wisconsin-Madison, USA - a review. Science.gov (United States) Thomas, David L; Berger, Yves M; McKusick, Brett C; Mikolayunas, Claire M 2014-01-01 Commercial milking of sheep is a new agricultural industry in the United States starting approximately 30 yr ago. The industry is still small, but it is growing. The majority of the sheep milk is used in the production of specialty cheeses. The United States is the major importer of sheep milk cheeses with 50 to 60% of annual world exports coming to the United States during the past 20 yr. Therefore, there is considerable growth potential for the industry in the United States. The only dairy sheep research flock in North America is located at the Spooner Agricultural Research Station of the University of Wisconsin-Madison. The research program started in 1993 and has been multifaceted; dealing with several areas important to commercial dairy sheep farmers. The East Friesian and Lacaune dairy breeds were compared and introduced to the industry through the research program. Both dairy breeds produced significantly more milk than traditional meat-wool breeds found in the U.S., but the two breeds differed in their production traits. East Friesian-cross ewes produced more lambs and slightly more milk than Lacaune-cross ewes whereas Lacaune-cross ewes produced milk with a higher percentage of fat and protein than East Friesian-cross ewes. Lactation physiology studies have shown that ewes with active corpora lutea have increased milk yields, oxytocin release during milking is required to obtain normal fat percentages in the milk, large udder cisterns of dairy ewes can allow for increased milking intervals, and short daylengths during late pregnancy results in increased milk yield. In the nutrition area, legume-grass pastures and forages with a higher percentage of legume will result in increased milk production. Grazing ewes respond to additional supplementation with increased milk yield, but it is important to match the supplement to the quality of the grazing. Ewes on high quality legume-grass pastures that are high in rumen degradable protein respond with increased 9.

Production of light elements by cascades from energetic antiprotons in the early Universe and problem of nuclear cosmoarcheology International Nuclear Information System (INIS) Levitan, Yu.L.; Sobol', I.M.; Khlopov, M.Yu.; Chechetkin, V.M. 1988-01-01 The mathematical model of the process of light-element (D and 3 He) production due to disintegration of 4 He nuclei, induced by nonequilibrium processes of production of energetic antiprotons in the early Universe is suggested. Numerical calculations show that formation of the nucleon cascade induced by antiproton slowing down increases the D and 3 He yield due to the growth of probability of disintegration of several 4 He nuclei by a single antiproton and due to disintegration of such nuclei by cascade protons. Restraints on the concentration of possible sources of energetic antiprotons in the early Universe are strengthened respectively 11.

Science.gov (United States) Ohtani, Kazuya; Hidaka, Takashi; Marubashi, Koichi; Takagi, Hirokazu; Kamimura, Naoki 2015-01-01 Many pharmacists have requested optimization of aluminum packaging of medicinal products in terms of usability. To improve operational efficiency of aluminum packaging, we used Universal Design (UD)-based approach, which enables products to be used properly and consistently regardless of users. The UD-pack used in this research is composed of a film that can be easily opened and torn linear. Here, we compared the UD-pack to conventional aluminum packaging by evaluating the practical use of each under the cooperation of 24 pharmacists. Following opening and removal of contents of one sample for both types of packaging, monitors were asked which type was easier to use in each case. Also, monitors were to repeat the opening and removal of contents of five samples in a row, and were asked the same question. Monitors were recorded by digital camera to measure the time required to finish the procedure for five samples in a row. After opening one sample, approximately 83% of monitors preferred the UD-pack, and after opening five samples, all (100%) preferred the UD-pack. Regarding the time required for opening five samples and removing the contents measured by analyzing the recorded video, the UD-pack significantly reduced the time required for all monitors. The average time ratio of the UD-pack to conventional aluminum packaging was approximately 59%, and no significant difference was observed between male and female pharmacists. Our results indicate the UD-pack improves ease of opening and removal of contents and increases efficiency of dispensing in a clinical setting compared with conventional aluminum packaging. 13. Production of large number of water-cooled excitation coils with improved techniques for multipole magnets of INDUS -2 International Nuclear Information System (INIS) Karmarkar, M.G.; Sreeramulu, K.; Kulshreshta, P.K. 2003-01-01 Accelerator multipole magnets are characterized by high field gradients powered with relatively high current excitation coils. Due to space limitations in the magnet core/poles, compact coil geometry is also necessary. The coils are made of several insulated turns using hollow copper conductor. High current densities in these require cooling with low conductivity water. Additionally during operation, these are subjected to thermal fatigue stresses. A large number of coils ( Qty: 650 nos.) having different geometries were required for all multipole magnets like quadrupole (QP), sextupole (SP). Improved techniques for winding, insulation and epoxy consolidation were developed in-house at M D Lab and all coils have been successfully made. Improved technology, production techniques adopted for magnet coils and their inspection are briefly discussed in this paper. (author) 14. Measurement of total acid number (TAN) and TAN boiling point distribution in petroleum products by electrospray ionization mass spectrometry. Science.gov (United States) Qian, Kuangnan; Edwards, Kathleen E; Dechert, Gary J; Jaffe, Stephen B; Green, Larry A; Olmstead, William N 2008-02-01 We report a new method for rapid measurement of total acid number (TAN) and TAN boiling point (BP) distribution for petroleum crude and products. The technology is based on negative ion electrospray ionization mass spectrometry (ESI-MS) for selective ionization of petroleum acid and quantification of acid structures and molecular weight distributions. A chip-based nanoelectrospray system enables microscale (boiling point distributions of TAN values can be calculated from the composition. The rapid measurement of TAN BP distributions by ESI is demonstrated for a series of high-TAN crudes and distillation cuts. TAN values determined by the technique agree well with those by the titration method. The distributed properties compare favorably with those measured by distillation and measurement of TAN of corresponding cuts. 15. High Quality Genomic Copy Number Data from Archival Formalin-Fixed Paraffin-Embedded Leiomyosarcoma: Optimisation of Universal Linkage System Labelling Science.gov (United States) Salawu, Abdulazeez; Ul-Hassan, Aliya; Hammond, David; Fernando, Malee; Reed, Malcolm; Sisley, Karen 2012-01-01 Most soft tissue sarcomas are characterized by genetic instability and frequent genomic copy number aberrations that are not subtype-specific. Oligonucleotide microarray-based Comparative Genomic Hybridisation (array CGH) is an important technique used to map genome-wide copy number aberrations, but the traditional requirement for high-quality DNA typically obtained from fresh tissue has limited its use in sarcomas. Although large archives of Formalin-fixed Paraffin-embedded (FFPE) tumour samples are available for research, the degradative effects of formalin on DNA from these tissues has made labelling and analysis by array CGH technically challenging. The Universal Linkage System (ULS) may be used for a one-step chemical labelling of such degraded DNA. We have optimised the ULS labelling protocol to perform aCGH on archived FFPE leiomyosarcoma tissues using the 180k Agilent platform. Preservation age of samples ranged from a few months to seventeen years and the DNA showed a wide range of degradation (when visualised on agarose gels). Consistently high DNA labelling efficiency and low microarray probe-to-probe variation (as measured by the derivative log ratio spread) was seen. Comparison of paired fresh and FFPE samples from identical tumours showed good correlation of CNAs detected. Furthermore, the ability to macro-dissect FFPE samples permitted the detection of CNAs that were masked in fresh tissue. Aberrations were visually confirmed using Fluorescence in situ Hybridisation. These results suggest that archival FFPE tissue, with its relative abundance and attendant clinical data may be used for effective mapping for genomic copy number aberrations in such rare tumours as leiomyosarcoma and potentially unravel clues to tumour origins, progression and ultimately, targeted treatment.

Science.gov (United States) Piechowski-Jozwiak, Bartlomiej; Boller, François; Bogousslavsky, Julien 2017-05-05 Art is defined as expression or application of human creative skill and imagination producing works to be appreciated primarily for their aesthetic value or emotional power. This definition encompasses two very important elements-the creation and reception of art-and by doing so it establishes a link, a dialogue between the artist and spectator. From the evolutionary biological perspective, activities need to have an immediate or remote effect on the population through improving survival, gene selection, and environmental adjustment, and this includes art. It may serve as a universal means of communication bypassing time, cultural, ethnic, and social differences. The neurological mechanisms of both art production and appreciation are researched by neuroscientists and discussed both in terms of healthy brain biology and complex neuronal networking perspectives. In this paper, we describe folk art and the issue of symbolic archetypes in psychoanalytic thought as well as offer neuronal mechanisms for art by emphasizing mirror/neurons and the role they play in it. 17. Scholarship as Cultural Production in the Neoliberal University: Working Within and Against ‘Deliverables’ Directory of Open Access Journals (Sweden) Mary Elizabeth Luka 2016-03-01 Full Text Available This article focuses on the idea of scholarly work as cultural production to help understand how the tensions of precarious, early-career academic employment are articulated on a day-to-day basis in the context of pressures to efficiently produce monetizable ‘deliverables.’ Using a political economy of communication framework and an iterative methodological approach, the authors mobilize examples drawn from a collaborative set of activities they undertook as part of a broader research group of emerging Canadian scholars working in different international contexts between 2012 and 2015. The research conversation began in academic roundtables in 2013, and was furthered through a content analysis of articles collected from scholarly and general interest blog posts, newsletters, and magazines published online from July 2012 to April 2014. In this article, the authors explore emerging themes and document pressures to conform to neoliberal practices within the corporatized university, as well as suggest pathways for dissent and reinvention of academic labour. 18. Patenting productivity and intellectual property policies at Research I universities: An exploratory comparative study. Directory of Open Access Journals (Sweden) Pilar Mendoza 2005-01-01 Full Text Available In the 1980s, the US government encouraged the cooperation of industries with universities in order to bridge funding gaps and cope with global competitive markets through legislations that allow universities to start spin-off businesses and to generate profits from patents. At the turn of the century, university partnerships with the private sector have greatly increased through research grants, licensing patents, and in some cases, the formation of new firms'mainly at research universities and in the hard sciences. In response to these entrepreneurial opportunities, university administrators developed intellectual property policies to facilitate the commercialization of research. The purpose of this study is to explore the differences across IP policies among nine research universities as potential sources of influence on faculty engagement in for-profit research ventures according to existing models of faculty role performance and achievement. 19.

Relationship between partnership working and employees’ productivity in a University of Medical Sciences in the South of Iran Directory of Open Access Journals (Sweden) Mohammad Khammarnia 2016-07-01 Full Text Available Introduction: Partnership working plays an important role in the health system, results in delivery of coordinated packages of services to patients, and reduces the impact of organizational fragmentation. Method: The study aimed to determine the relationship between partnership working and productivity in the employees of a university of medical sciences in the south of Iran. Results: According to the result, partnership and productivity scores were 51.1 + 6.7 and 51.9 + 13.4, respectively. Partnership working had a positive relationship with productivity (r = 0.333, P = 0.001 and age of the employees (r = 0.142, P = 0.007. There was a negative relationship between the employees’ productivity with age and job position in ZAUMS (P= 0.009 and P= 0.001, respectively. The nurses had the highest score of productivity (mean=60.7±13.3. Moreover, employees with an Ph.D. degree (9 persons had the highest scores of partnership and productivity in ZAUMS (53.6±3.1 and 56.8±6.3, respectively. Conclusion: Enhancement of partnership working could increase the employees’ productivity in the health system. It is recommended that younger persons should be used in universities of medical science. Moreover, supportive staff should increase their partnership working to enhance the individual and organizational productivity. 1.

Wake vortex properties and thrust production of a harmonically-pitching flexible airfoil at low Reynolds number Science.gov (United States) Olson, David; Naguib, Ahmed; Koochesfahani, Manoochehr 2017-11-01 Many of the natural flyers have deformable wing structures and exhibit complex kinematics in order to produce lift and thrust. Replicating all of these conditions in the laboratory (or in simulations) is extremely difficult, and drawing explicit connections to basic unsteady aerodynamics models and theories is even more complicated. Therefore, simplified wing structure and kinematics are typically used to facilitate drawing out these connections. In this work, measurements are conducted using a rigid and a chordwise-flexible NACA 0009 airfoils when harmonically pitched about the quarter chord point. Molecular tagging velocimetry is used to characterize the wake and estimate the thrust based on the momentum integral equation as function of the reduced frequency and the pitching amplitude. The results obtained using the two different airfoils are compared in order to examine the influence of structural flexibility. Consistent with the literature, chordwise flexibility is found to enhance thrust production and the circulation of the vortices shed into the wake, for a certain range of frequencies and amplitudes. Additional characterizations are undertaken of the wake vortex structure and its scaling. This work was supported by AFOSR Award Number FA9550-10-1-0342. 7. Identification and analysis of labor productivity components based on ACHIEVE model (case study: staff of Kermanshah University of Medical Sciences). Science.gov (United States) Ziapour, Arash; Khatony, Alireza; Kianipour, Neda; Jafary, Faranak 2014-12-15 Identification and analysis of the components of labor productivity based on ACHIEVE model was performed among employees in different parts of Kermanshah University of Medical Sciences in 2014. This was a descriptive correlational study in which the population consisted of 270 working personnel in different administrative groups (contractual, fixed- term and regular) at Kermanshah University of Medical Sciences (872 people) that were selected among 872 people through stratified random sampling method based on Krejcie and Morgan sampling table. The survey tool included labor productivity questionnaire of ACHIEVE. Questionnaires were confirmed in terms of content and face validity, and their reliability was calculated using Cronbach's alpha coefficient. The data were analyzed by SPSS-18 software using descriptive and inferential statistics. The mean scores for labor productivity dimensions of the employees, including environment (environmental fit), evaluation (training and performance feedback), validity (valid and legal exercise of personnel), incentive (motivation or desire), help (organizational support), clarity (role perception or understanding), ability (knowledge and skills) variables and total labor productivity were 4.10±0.630, 3.99±0.568, 3.97±0.607, 3.76±0.701, 3.63±0.746, 3.59±0.777, 3.49±0.882 and 26.54±4.347, respectively. Also, the results indicated that the seven factors of environment, performance assessment, validity, motivation, organizational support, clarity, and ability were effective in increasing labor productivity. The analysis of the current status of university staff in the employees' viewpoint suggested that the two factors of environment and evaluation, which had the greatest impact on labor productivity in the viewpoint of the staff, were in a favorable condition and needed to be further taken into consideration by authorities. 8.

A Study on the Knowledge, Attitude and Behavior of University Students’ Towards the Well Known Branded Products Directory of Open Access Journals (Sweden) Azize Hassan 2011-12-01 Full Text Available Nowadays branding, marketing literature appears to be an important concept. Consumers' attitudes towards goods and services together with increased levels of education also have become more sensitive. Many of the young people are the actual mass for the brand. At this point, young people's attitudes towards brands and information are important to determine the behavior. Heading from this importance, it was tried to measure knowledge, attitude and behavior of high brand awareness for products among 384 students who are learning in Gölbaşı Campus of Gazi University. As a result of this research it was found that the joining students preferred the high brand awareness products. Accordingly, high brand awareness products are seen by students, as mostly reliable products, which provides possibility of protection to consumers that can be easily found on the shelves and have more promotions but they are thinking that their prices are not the same everywhere. 10. Universal real-time control framework and Internet of Things for fast-paced research and development based production environments KAUST Repository Chaoui, Hicham 2017-05-13 This paper introduces a universal real-time control platform for complex research and development (R&D) based products design. The inherent complexity in R&D projects makes products development a difficult task to undertake. The use of state of the art development tools for modeling, simulation, and hardware-in-the-loop (HIL) validation contributes to a complexity reduction. However, R&D projects still require significant development time since many design iterations are usually necessary before final solution, which increases the cost. In most R&D processes, these tools are not used beyond rapid prototyping since development for mass production is usually performed in another environment, using different tools. This paper presents a fast and cost effective way of R&D-based products development, speeding-up time to market. 11.

Government-industry-uUniversity and rResearch lLaboratories cCoordination for new product development: Session 2. Government research laboratory perspective International Nuclear Information System (INIS) Kuzay, T.M. 1997-01-01 This talk is the second in an expanded series of presentations on the Government-Industry-University and Research Laboratories Coordination for new product development, which is a timely and important public policy issue. Such interactions have become particularly timely in light of the present decline in funding for research and development (R ampersand D) in the nation''s budget and in the private sector. These interactions, at least in principle, provide a means to maximize benefits for the greater good of the nation by pooling the diminishing resources. National laboratories, which traditionally interacted closely with the universities in educational training, now are able to also participate closely with industry in joint R ampersand D thanks to a number of public laws legislated since the early 80s. A review of the experiences with such interactions at Argonne National Laboratory, which exemplifies the national laboratories, shows that, despite differences in their traditions and the missions, the national laboratory-industry-university triangle can work together 13.

EDUCATIVE INNOVATION PROCESS IN UNIVERSITY FORMATION, NEW PRODUCTIVE BESTS PRACTICES IN EDUCATIVE TECHNOLOGY Directory of Open Access Journals (Sweden) Bartolomé Rubia-Avi 2010-02-01 Full Text Available The influence of educational innovation in the transformation of Spanish Universities to achieved the goals posed by the European Higher Education Area is a crucial aspect for this reform. This process of deep impact within the European countries is promoting the revision of traditional teaching methods. Small groups of teachers and communities of practice are leading this revision by reflecting upon the main issues affecting the higher education system at the same time that they propose horizontal innovations to overcome them. Information and Communication Technologies are becoming of special relevance with regard to the aforementioned innovations. This paper describes a experience conducted within the GSIC-EMIC research team that illustrates the efforts done by a community of teachers at the University of Valladolid (Spain to analyze and improve their own teaching practices. 18. First-year university students’ receptive and productive use of academic vocabulary Directory of Open Access Journals (Sweden) Déogratias Nizonkiza 2016-05-01 Full Text Available The present study explores academic vocabulary knowledge, operationalised through the Academic Word List, among first-year higher education students. Both receptive and productive knowledge and the proportion between the two are examined. Results show that while receptive knowledge is readily acquired by first-year students, productive knowledge lags behind and remains problematic. This entails that receptive knowledge is much larger than productive knowledge, which confirms earlier indications that receptive vocabulary knowledge is larger than productive knowledge for both academic vocabulary (Zhou 2010 and general vocabulary (cf. Laufer 1998, Webb 2008, among others. Furthermore, results reveal that the ratio between receptive and productive knowledge is slightly above 50%, which lends empirical support to previous findings that the ratio between the two aspects of vocabulary knowledge can be anywhere between 50% and 80% (Milton 2009. This finding is extended here to academic vocabulary; complementing Zhou’s (2010 study that investigated the relationship between the two aspects of vocabulary knowledge without examining the ratio between them. On the basis of these results, approaches that could potentially contribute to fostering productive knowledge growth are discussed. Avenues worth exploring to gain further insight into the relationship between receptive and productive knowledge are also suggested. 19. Axino dark matter and baryon number asymmetry production by the Q-ball decay in gauge mediation Energy Technology Data Exchange (ETDEWEB) Kasuya, Shinta [Department of Mathematics and Physics, Kanagawa University, Kanagawa 259-1293 (Japan); Kawakami, Etsuko; Kawasaki, Masahiro, E-mail: kasuya@kanagawa-u.ac.jp, E-mail: kwkm@icrr.u-tokyo.ac.jp, E-mail: kawasaki@icrr.u-tokyo.ac.jp [Institute for Cosmic Ray Research, University of Tokyo, Chiba 277-8582 (Japan) 2016-03-01 We investigate the Q-ball decay into the axino dark matter in the gauge-mediated supersymmetry breaking. In our scenario, the Q ball decays mainly into nucleons and partially into axinos to account respectively for the baryon asymmetry and the dark matter of the universe. The Q ball decays well before the big bang nucleosynthesis so that it is not affected by the decay. We show the region of the parameters which realizes this scenario. 20. A Universal Ts-VI Triangle Method for the Continuous Retrieval of Evaporative Fraction From MODIS Products Science.gov (United States) Zhu, Wenbin; Jia, Shaofeng; Lv, Aifeng 2017-10-01 The triangle method based on the spatial relationship between remotely sensed land surface temperature (Ts) and vegetation index (VI) has been widely used for the estimates of evaporative fraction (EF). In the present study, a universal triangle method was proposed by transforming the Ts-VI feature space from a regional scale to a pixel scale. The retrieval of EF is only related to the boundary conditions at pixel scale, regardless of the Ts-VI configuration over the spatial domain. The boundary conditions of each pixel are composed of the theoretical dry edge determined by the surface energy balance principle and the wet edge determined by the average air temperature of open water. The universal triangle method was validated using the EF observations collected by the Energy Balance Bowen Ratio systems in the Southern Great Plains of the United States of America (USA). Two parameterization schemes of EF were used to demonstrate their applicability with Terra Moderate Resolution Imaging Spectroradiometer (MODIS) products over the whole year 2004. The results of this study show that the accuracy produced by both of these two parameterization schemes is comparable to that produced by the traditional triangle method, although the universal triangle method seems specifically suited to the parameterization scheme proposed in our previous research. The independence of the universal triangle method from the Ts-VI feature space makes it possible to conduct a continuous monitoring of evapotranspiration and soil moisture. That is just the ability the traditional triangle method does not possess. 1. Integrating medical, assistive, and universal design products and technologies: Assistive Technology Service Method (ATSM). Science.gov (United States) Elsaesser, Linda-Jeanne; Bauer, Stephen 2012-07-01 ISO26000 provides guidance on effective organizational performance that recognizes social responsibility (including rights of persons with disabilities (PWD)), engages stakeholders, and contributes to sustainable development [1]. Millennium Development Goals 2010 state: while progress has been made, insufficient dedication to sustainable development, and inequalities to the most vulnerable people require attention [2]. World Report on Disability 2011 recommendations includes improved data collection and removal of barriers to rehabilitation that empower PWD [3]. The Assistive Technology Service Method (ATSM), Assistive Technology Device Classification (ATDC) and Matching Person and Technology (MPT) provide an evidence-based, standardized, internationally comparable framework to improve rehabilitation interventions [4-6]. The ATSM and ATDC support universal design (UD) principles and provision of universal technology. The MPT assures interventions are effective and satisfactory to end-users [7]. The ICF conceptual framework and common language are used throughout [8]. Research findings on healthcare needs are translated. ATSM applications in support of these findings are presented. National initiatives demonstrate the need and value of the ATSM as an evidence-based, user-centric, interdisciplinary method to improve individual and organizational performance for rehabilitation [including AT] services. Two Disability & Rehabilitation: Assistive Technology articles demonstrate ATSM and ATDC use to strengthen rehabilitation services and integrate Universal Design principles for socially responsible behavior. 2.

Sensitivity analysis of the effect of various key parameters on fission product concentration (mass number 120 to 126) International Nuclear Information System (INIS) Sola, A. 1978-01-01 An analytical sensitivity analysis has been made of the effect of various parameters on the evaluation of fission product concentration. Such parameters include cross sections, decay constants, branching ratios, fission yields, flux and time. The formulae are applied to isotopes of the Tin, Antimony and Tellurium series. The agreement between analytically obtained data and that derived from a computer evaluated model is good, suggesting that the analytical representation includes all the important parameters useful to the evaluation of the fission product concentrations 4. Developments in the production of economics PhDs at four research-intensive universities in South Africa Directory of Open Access Journals (Sweden) Phillip de Jager 2017-03-01 Full Text Available There is a national drive to increase PhD production, yet we know little about how this imperative takes shape within different disciplines. We therefore set out to explore recent developments and the current status of the PhD in economics at four South African research-intensive universities. A data set of all economics PhDs produced in these commerce faculties during the period 2008-2014 was analysed to determine whether the departments of economics responded to the call for increased doctoral production, and the role the PhD by publication might have played in the process. How an increase in quantity might influence doctoral education in the respective academic departments was also considered by supplementing the quantitative data with perspectives from heads of department at the four institutions. The notable increase in doctoral production over the time period studied shows that national and international trends have influenced doctoral education in economics departments within South African research-intensive universities. Increased usage of the PhD by publication has implications for policy and pedagogical practice within these departments, especially as there seems to be limited available supervisory capacity. Other changes in departmental practices, such as the entrenchment of a research culture and the promotion of collaborative research amongst students and staff, also contributed to maintain quality in doctoral education. 5. Asymmetric Switch Costs in numeral naming and number word reading: Implications for models of bilingual language production Directory of Open Access Journals (Sweden) Michael eReynolds 2016-01-01 Full Text Available One approach used to gain insight into the processes underlying bilingual language comprehension and production examines the costs that arise from switching languages. For unbalanced bilinguals, asymmetric switch costs are reported in speech production, where the switch cost for L1 is larger than the switch cost for L2, whereas, symmetric switch costs are reported in language comprehension tasks, where the cost of switching is the same for L1 and L2. Presently, it is unclear why asymmetric switch costs are observed in speech production, but not in language comprehension. Three experiments are reported that simultaneously examine methodological explanations of task related differences in the switch cost asymmetry and the predictions of three accounts of the switch cost asymmetry in speech production. The results of these experiments suggest that (1 the type of language task (comprehension vs. production determines whether an asymmetric switch cost is observed and (2 at least some of the switch cost asymmetry arises within the language system. 6. A Changing Number of Alternative States in the Boreal Biome: Reproducibility Risks of Replacing Remote Sensing Products. Science.gov (United States) Xu, Chi; Holmgren, Milena; Van Nes, Egbert H; Hirota, Marina; Chapin, F Stuart; Scheffer, Marten 2015-01-01 Publicly available remote sensing products have boosted science in many ways. The openness of these data sources suggests high reproducibility. However, as we show here, results may be specific to versions of the data products that can become unavailable as new versions are posted. We focus on remotely-sensed tree cover. Recent studies have used this public resource to detect multi-modality in tree cover in the tropical and boreal biomes. Such patterns suggest alternative stable states separated by critical tipping points. This has important implications for the potential response of these ecosystems to global climate change. For the boreal region, four distinct ecosystem states (i.e., treeless, sparse and dense woodland, and boreal forest) were previously identified by using the Collection 3 data of MODIS Vegetation Continuous Fields (VCF). Since then, the MODIS VCF product has been updated to Collection 5; and a Landsat VCF product of global tree cover at a fine spatial resolution of 30 meters has been developed. Here we compare these different remote-sensing products of tree cover to show that identification of alternative stable states in the boreal biome partly depends on the data source used. The updated MODIS data and the newer Landsat data consistently demonstrate three distinct modes around similar tree-cover values. Our analysis suggests that the boreal region has three modes: one sparsely vegetated state (treeless), one distinct 'savanna-like' state and one forest state, which could be alternative stable states. Our analysis illustrates that qualitative outcomes of studies may change fundamentally as new versions of remote sensing products are used. Scientific reproducibility thus requires that old versions remain publicly available. 7. Effect of μe universality violation in muon pair production on colliding electron-positron beams International Nuclear Information System (INIS) Guliev, N.A.; Dzhafarov, I.G.; Mekhtiev, B.I. 1981-01-01 The muonic pair production in colliding electron-positron beams is treated assuming the electron and muon weak interaction constants to be different. General formulae for the differential and total cross sections applicable at arbitrary energies of the colliding beams are obtained taking simultaneously into account arbitrary polarizations of the incident particles and longitudinal polarization of the muon (μ - ). It is shown that study of some polarization characteristics of a given reaction allows to distinguish possible weak interaction μe universality breaking effects. The revealing effects are analysed in the framework of unified gauge SU(2)xU(1) models, of weak and electromagnetic interactions [ru 8. The role of the University in the context of Inclusive Education Policy: reflections about human resources formation and knowledge production Directory of Open Access Journals (Sweden) Rosana Glat 2010-12-01 Full Text Available The present text aims to discuss and present, briefly action lines about the role of University in the promotion of psicossocial and educational development of people with handicap and other special needs. Taking the framework of specialized literature, it brings different questions dealing with human resources formation, specially, teacher formation, and the production of knowledge in the area of Special Education, obtained through research and extension projects, done, preferentially, in partnership with the educational agents that work in the field. It also analyses how these actions may influence the implementation of policies regarding school, labor, and social inclusion of people with handicap and other developmental disorders. 9. Universal empirical fit to L-shell X-ray production cross sections in ionization by protons Science.gov (United States) Lapicki, G.; Miranda, J. 2018-01-01 A compilation published in 2014, with a recent 2017 update, contains 5730 experimental total L-shell X-ray production cross sections (XRPCS). The database covers an energy range from 10 keV to 1 GeV, and targets from 18Ar to 95Am. With only two adjustable parameters, universal fit to these data normalized to XRPCS calculated at proton velocity v1 equal to the electron velocity in the L-shell v2L, is obtained in terms of a single ratio of v1/v2L. This fit reproduces 97% of the compiled XRPCS to within a factor of 2. 10.

Factors affecting the number and type of student research products for chemistry and physics students at primarily undergraduate institutions: A case study. Science.gov (United States) Mellis, Birgit; Soto, Patricia; Bruce, Chrystal D; Lacueva, Graciela; Wilson, Anne M; Jayasekare, Rasitha 2018-01-01 For undergraduate students, involvement in authentic research represents scholarship that is consistent with disciplinary quality standards and provides an integrative learning experience. In conjunction with performing research, the communication of the results via presentations or publications is a measure of the level of scientific engagement. The empirical study presented here uses generalized linear mixed models with hierarchical bootstrapping to examine the factors that impact the means of dissemination of undergraduate research results. Focusing on the research experiences in physics and chemistry of undergraduates at four Primarily Undergraduate Institutions (PUIs) from 2004-2013, statistical analysis indicates that the gender of the student does not impact the number and type of research products. However, in chemistry, the rank of the faculty advisor and the venue of the presentation do impact the number of research products by undergraduate student, whereas in physics, gender match between student and advisor has an effect on the number of undergraduate research products. This study provides a baseline for future studies of discipline-based bibliometrics and factors that affect the number of research products of undergraduate students. 17.

Literature and Imagology: a productive interaction: the contribution of comparative literature at the University of Aache Directory of Open Access Journals (Sweden) Celeste H. M. Ribeiro de Sousa 2011-01-01 Full Text Available The University of Aachen harbored for years the main centre of Studies on Imagology of Germany and perhaps of the world. The Center was founded by Hugo Dyserinck, who, in 1966, with the article "Zum Problem der 'images' und 'mirages' und ihrer Untersuchung im Rahmen der vergleichenden Literaturwissenschaft" opened the doors to a new Imagology. He gathered there disciples, who roamed the new horizons with extensive research, which led to the publication of the collection "Aachener Beiträge zur Komparatistik". In Brazil, the influence of Dyserinck was also felt, for example, in the publication of my book Do cá e do lá. Introdução à Imagologia, whose content is in part commented and illustrated. 19.

Penicillin production in industrial strain Penicillium chrysogenum P2niaD18 is not dependent on the copy number of biosynthesis genes. Science.gov (United States) Ziemons, Sandra; Koutsantas, Katerina; Becker, Kordula; Dahlmann, Tim; Kück, Ulrich 2017-02-16 Multi-copy gene integration into microbial genomes is a conventional tool for obtaining improved gene expression. For Penicillium chrysogenum, the fungal producer of the beta-lactam antibiotic penicillin, many production strains carry multiple copies of the penicillin biosynthesis gene cluster. This discovery led to the generally accepted view that high penicillin titers are the result of multiple copies of penicillin genes. Here we investigated strain P2niaD18, a production line that carries only two copies of the penicillin gene cluster. We performed pulsed-field gel electrophoresis (PFGE), quantitative qRT-PCR, and penicillin bioassays to investigate production, deletion and overexpression strains generated in the P. chrysogenum P2niaD18 background, in order to determine the copy number of the penicillin biosynthesis gene cluster, and study the expression of one penicillin biosynthesis gene, and the penicillin titer. Analysis of production and recombinant strain showed that the enhanced penicillin titer did not depend on the copy number of the penicillin gene cluster. Our assumption was strengthened by results with a penicillin null strain lacking pcbC encoding isopenicillin N synthase. Reintroduction of one or two copies of the cluster into the pcbC deletion strain restored transcriptional high expression of the pcbC gene, but recombinant strains showed no significantly different penicillin titer compared to parental strains. Here we present a molecular genetic analysis of production and recombinant strains in the P2niaD18 background carrying different copy numbers of the penicillin biosynthesis gene cluster. Our analysis shows that the enhanced penicillin titer does not strictly depend on the copy number of the cluster. Based on these overall findings, we hypothesize that instead, complex regulatory mechanisms are prominently implicated in increased penicillin biosynthesis in production strains. 1. Evaluation of the production capabilities of 18F, 11C, 13N and 15O PET isotopes at the PET-cyclotron-radiochemistry site of Messina University OpenAIRE Auditore, Lucrezia; Amato, Ernesto; Italiano, Antonio; Pagano, Benedetta; Baldari, Sergio 2017-01-01 The production of 18F, 11C, 13N, and 15O positron emitting radionuclides for PET imaging is usually accomplished in Nuclear Medicine Departments through direct nuclear reactions induced by protons accelerated by compact medical cyclotrons on liquid or gaseous targets. Messina University has funded the construction of a PET-cyclotron-radio-chemistry plant at the Messina University Hospital, equipped with a 11 MeV self-shielded cyclotron. We estimated the expected production yields of these nuc... 2. Cross-Cultural and Intra-Cultural Differences in Finger-Counting Habits and Number Magnitude Processing: Embodied Numerosity in Canadian and Chinese University Students Directory of Open Access Journals (Sweden) Kyle Richard Morrissey 2016-04-01 Full Text Available Recent work in numerical cognition has shown-that number magnitude is not entirely abstract, and at least partly rooted in embodied and situated experiences, including finger-counting. The current study extends previous cross-cultural research to address within-culture individual differences in finger counting habits. Results indicated that Canadian participants demonstrated an additional cognitive load when comparing numbers that require more than one hand to represent, and this pattern of performance is further modulated by whether they typically start counting on their left hand or their right hand. Chinese students typically count on only one hand and so show no such effect, except for an increase in errors, similar to that seen in Canadians, for those whom self-identify as predominantly two-hand counters. Results suggest that the impact of finger counting habits extend beyond cultural experience and concord in predictable ways with differences in number magnitude processing for specific number-digits. We conclude that symbolic number magnitude processing is partially rooted in learned finger-counting habits, consistent with a motor simulation account of embodied numeracy and that argument is supported by both cross-cultural and within-culture differences in finger-counting habits. 3. Argon-41 production and evolution at the Oregon State University TRIGA Reactor (OSTR) International Nuclear Information System (INIS) Anellis, L.G.; Johnson, A.G.; Higginbotham, J.F. 1988-01-01 In this study, argon-41 concentrations were measured at various locations within the reactor facility to assess the accuracy of models used to predict argon-41 evolution from the reactor tank, and to determine the relationship between argon gas evolution from the tank and subsequent argon-41 concentrations throughout the reactor room. In particular, argon-41 was measured directly above the reactor tank with the reactor tank lids closed, at other accessible locations on the reactor top with the tank lids both closed and open, and at several locations on the first floor of the reactor room. These measured concentrations were then compared to values calculated using a modified argon-41 production and evolution model for TRIGA reactor tanks and ventilation values applicable to the OSTR facility. The modified model was based in part on earlier TRIGA models for argon-41 production and release, but added features which improved the agreement between predicted and measured values. The approximate dose equivalent rate due to the presence of argon-41 in reactor room air was calculated for several different locations inside the OSTR facility. These dose rates were determined using the argon-41 concentration measured at each specific location, and were subsequently converted to a predicted quarterly dose equivalent for each location based on the reactor's operating history. The predicted quarterly dose equivalent values were then compared to quarterly doses measured by film badges deployed as dose-integrating area radiation monitors at the locations of interest. The results indicate that the modified production and evolution model is able to predict argon-41 concentrations to within a factor of ten when compared to the measured data. Quarterly dose equivalents calculated from the measured argon-41 concentrations and the reactor's operating history seemed consistent with results obtained from the integrating area radiation monitors. Given the argon-41 concentrations measured 4. A Universal Rig for Supporting Large Hammer Drills: Reduced Injury Risk and Improved Productivity. Science.gov (United States) Rempel, David; Barr, Alan 2015-10-01 Drilling holes into concrete with heavy hammer and rock drills is one of the most physically demanding tasks performed in commercial construction and poses risks for musculoskeletal disorders, noise induced hearing loss, hand arm vibration syndrome and silicosis. The aim of this study was to (1) use a participatory process to develop a rig to support pneumatic rock drills or large electric hammer drills in order to reduce the health risks and (2) evaluate the usability of the rig. Seven prototype rigs for supporting large hammer drills were developed and modified with feedback from commercial contractors and construction workers. The final design was evaluated by laborers and electricians (N=29) who performed their usual concrete drilling with the usual method and the new rig. Subjective regional fatigue was significantly less in the neck, shoulders, hands and arms, and lower back) when using the universal rig compared to the usual manual method. Usability ratings for the rig were significantly better than the usual method on stability, control, drilling, accuracy, and vibration. Drilling time was reduced by approximately 50% with the rig. Commercial construction contractors, laborers and electricians who use large hammer drills for drilling many holes should consider using such a rig to prevent musculoskeletal disorders, fatigue, and silicosis. 5. Cascade Production of Lactic Acid from Universal Types of Sugars Catalyzed by Lanthanum Triflate. Science.gov (United States) Liu, Dajiang; Kim, Kwang Ho; Sun, Jian; Simmons, Blake A; Singh, Seema 2018-02-09 Lignocellulosic biomass conversion into value-added platform chemicals in the non-toxic, water-tolerant Lewis acid, and water solutions bears the hallmark of green chemistry. Lactic acid derived from biomass is an important chemical building block for biodegradable polymers such as polylactide. Herein, a universal method of converting lignocellulosic sugars into lactic acid using catalytic amount of water-stable Lewis acid La(OTf) 3 is demonstrated. The lignocellulosic sugars studied in this work include 1) pyrolytic sugars from pyrolysis oil, and 2) sugars derived from ionic liquid (IL)-pretreated biomass. Under moderate conditions (250 °C, 1 h), levoglucosan (major pyrolytic sugar), glucose, and xylose were converted into lactic acid with carbon-based molar yields of 75, 74, and 61 %, respectively. Furthermore, roughly 49 mol % (based on levoglucosan) and 74 wt % (relative to pretreated biomass) of lactic acid were obtained from the conversion of pyrolytic sugars and sugar-rich fraction after lignin removal from switchgrass, respectively. To our knowledge, this is the first reported conversion of pyrolytic sugar into lactic acid by chemocatalysis and also lignocellulosic sugars are converted into lactic acid without hydrolysis. This approach could potentially be extended to other lignocellulosic sugars after simple removal of lignin from biomass pretreatment, rendering moderate to high yields of lactic acid. © 2018 Wiley-VCH Verlag GmbH & Co.

The Baryon Production and Baryon Number Transfer in Hadron-Hadron, Hadron-Nucleus and Nucleus-Nucleus Collisions International Nuclear Information System (INIS) Szymanski, P. 2006-09-01 This work concerns soft hadronic interactions which in the Standard Model carry most of the observable cross-section but are not amenable to quantitative predictions due to the very nature of the QCD (Theory of Strong Interactions). In the low momentum transfer region the evolving coupling constant caused perturbation theory to break down. In this situation better experimental understanding of the physics phenomena is needed. One aspect of the soft hadronic interactions will be discussed in this work: transfer of the baryon number from the initial to the final state of the interaction. The past experimental knowledge on this process is presented, reasons for its unsatisfactory status are discussed and condition necessary for improvement are outlined: that is experimental apparatus with superior performance over the full range of available interactions: hadron-hadron collision, hadron-nucleus and nucleus-nucleus interactions. A consistent model-independent picture of the baryon number transfer process emerging from the data on the full range of interactions is shown. It offers serious challenge to theory to provide quantitative and detailed explanation of the measurements. (author) 8.

Confronting fragmentation function universality with single hadron inclusive production at HERA and e+e- colliders International Nuclear Information System (INIS) Albino, S.; Kniehl, B.A.; Kramer, G.; Sandoval, C. 2006-11-01 Predictions for light charged hadron production data in the current fragmentation region of deeply inelastic scattering from the H1 and ZEUS experiments are calculated using perturbative Quantum Chromodynamics at next-to-leading order, and using fragmentation functions obtained by fitting to similar data from e + e - reactions. General good agreement is found when the magnitude Q 2 of the hard photon's virtuality is sufficiently large. The discrepancy at low Q and small scaled momentum x p is reduced by incorporating mass effects of the detected hadron. By performing quark tagging, the contributions to the overall fragmentation from the various quark flavours in the ep reactions are studied and compared to the contributions in e + e - reactions. The yields of the various hadron species are also calculated. (orig.) 11. Production and characterization of protonated molecular clusters containing a given number of water molecules with the DIAM set-up International Nuclear Information System (INIS) Bruny, G. 2010-01-01 nano-scale characterization of irradiation in bio-molecular systems requires observation of novel features which are now achievable with the recent technical progress. This work is a central part in the development of DIAM which is a new experimental set-up devoted to irradiation of bio-molecular clusters at the Institut de Physique Nucleaire de Lyon. The development of the cluster source and of a double focusing mass spectrometer leads to the production of intense beams of mass selected protonated molecular clusters. Combined with this mass selected cluster beams an innovative detection technique is demonstrated in collision induced dissociation experiments. The results contribute to the knowledge of the stability and the structure of the small protonated water clusters and mixed clusters of water and pyridine. (author) 12.

Challenges of scientific knowledge visualization in publication productivity of the university academic staff Directory of Open Access Journals (Sweden) Kabanova Natalia N. 2016-01-01 Full Text Available It has recently been shown that a person, an author particularly, faces the challenges of visualization in the cognitive process. The aim of this study is to consider the forms of thinking process and the changes happened in education process and in scientific activity. It was noted that the challenges connected with information perceiving during the work with the text occur in the process of creating academic papers as well. We conclude that the topical field of visualization covers not only the educative process assuming information transfer from person to person (model “teacher-student”, but the process of scientific activity. Applying the methods of visualization in publication activity is the factor for effective communication in social and cultural space that provides the opportunity for academic society to recognize results. We offer possible ways to promote scientific papers via online resources such as scientific social networks and tools of media corporations. The scientific social network ResearchGate and Thomson Reuters media corporation product as an online tool “Researcher ID” placed at the bibliographic database Web of Science TM Core Collection are used as the examples. We state that information technology allows authors to promote the results of their studies around the world. 14. Research progress in intense ion beam production for inertial confinement fusion at Cornell University International Nuclear Information System (INIS) Bluhm, H.; Greenly, J.B.; Hammer, D.A. 1983-01-01 Recent results obtained in the generation of intense pulsed light ion beams and their application to inertial confinement fusion are described. Studies of time-integrated and time-dependent beam divergence using a magnetically insulated ion diode with a ''flashboard'' anode at 11 W diode power show a directionality which is apparently due to electron dynamics in the diode. Nevertheless, ion beams having divergence angle as small as 0.5 0 have been produced at >10 8 W.cm - 2 . In another experiment with a similar diode, the anode plasma formation time varied with the detailed anode configuration, the diode voltage and the insulating magnetic field, with the longer times obtained at lower voltage and higher insulating magnetic field strength. The anode plasma density was determined to be in the 10 15 cm - 3 density range and to move away from the anode at approx.2 cm.μs - 1 in another similar experiment. Preliminary experiments performed on a 10 12 W accelerator show reasonable power coupling to a magnetically insulated ion diode, with >10 9 W.cm - 2 beams at approx.1.5 MV being generated. Computer simulations suggest that if such a beam can be focused into a plasma channel, most of its energy can be delivered to a pellet one to two metres away. In experiments on the applied Bsub(theta) diode, microwave radiation, ion production efficiency, and ion beam fluctuations all reach a maximum when the insulating magnetic field is about 1.4 times the critical field for magnetic insulation. Finally, relatively pure beams of heavy ions have been produced by making the anode with hydrocarbon-free dielectric material which contains the desired species together with other ions having substantially higher ionization potential. The sum of these results suggests that flashboard anodes operated at the few-MV level can be used to produce beams with properties suitable for inertial confinement fusion experiments on sufficiently powerful pulsed power generators.

Science.gov (United States) Petersen, Margit Anne; Nørgaard, Lotte Stig; Traulsen, Janine M 2015-12-01 This article presents ethnographic data on the use of prescription stimulants for enhancement purposes by university students in New York City. The study shows that students find stimulants a helpful tool in preventing procrastination, particularly in relation to feeling disinterested, overloaded, or insecure. Using stimulants, students seek pleasure in the study situation, for example, to get rid of unpleasant states of mind or intensify an already existing excitement. The article illustrates the notion that enhancement strategies do not only concern productivity in the quantitative sense of bettering results, performances, and opportunities. Students also measure their own success in terms of the qualitative experience of working hard. The article further argues that taking an ethnographic approach facilitates the study of norms in the making, as students experience moral uncertainty-not because they improve study skills and results-but because they enhance the study experience, making work fun. The article thereby seeks to nuance simplistic neoliberal ideas of personhood. 16. First Time Rapid and Accurate Detection of Massive Number of Metal Absorption Lines in the Early Universe Using Deep Neural Network Science.gov (United States) Zhao, Yinan; Ge, Jian; Yuan, Xiaoyong; Li, Xiaolin; Zhao, Tiffany; Wang, Cindy 2018-01-01 Metal absorption line systems in the distant quasar spectra have been used as one of the most powerful tools to probe gas content in the early Universe. The MgII λλ 2796, 2803 doublet is one of the most popular metal absorption lines and has been used to trace gas and global star formation at redshifts between ~0.5 to 2.5. In the past, machine learning algorithms have been used to detect absorption lines systems in the large sky survey, such as Principle Component Analysis, Gaussian Process and decision tree, but the overall detection process is not only complicated, but also time consuming. It usually takes a few months to go through the entire quasar spectral dataset from each of the Sloan Digital Sky Survey (SDSS) data release. In this work, we applied the deep neural network, or “ deep learning” algorithms, in the most recently SDSS DR14 quasar spectra and were able to randomly search 20000 quasar spectra and detect 2887 strong Mg II absorption features in just 9 seconds. Our detection algorithms were verified with previously released DR12 and DR7 data and published Mg II catalog and the detection accuracy is 90%. This is the first time that deep neural network has demonstrated its promising power in both speed and accuracy in replacing tedious, repetitive human work in searching for narrow absorption patterns in a big dataset. We will present our detection algorithms and also statistical results of the newly detected Mg II absorption lines. 17. Productive interactions for societal impact: Developing a research information system for agriculture (RIS-Agric) at Stellenbosch University, South Africa Energy Technology Data Exchange (ETDEWEB) Boshoff, N.; Esterhuyse, H. 2016-07-01 Assessments of the societal impact of research rely on primary data as input to the relevant indicators. In the current project, the data collection for indicator construction is guided by the SIAMPI approach to societal impact assessment. According to SIAMPI, the achievement of societal impact involves two elements: stakeholders and productive interactions. The latter includes three kinds of interactions: direct personal interactions; indirect interactions where contact is mediated by a material or human ‘carrier’; and financial interactions that refer to the economic exchanges between researchers and stakeholders. The question to be explored is whether the assessment of the societal impact of research can be facilitated by capturing any direct, indirect and financial interactions between researchers and societal stakeholders in a research information system. CREST/SciSTIP is developing such a system, called RIS-Agric, in cooperation with the Faculty of AgriSciences at Stellenbosch University and four agricultural research funders in South Africa that represent different agricultural commodities. A RIS with productive interactions at its core – and the funded research project as the unit of observation – will produce the necessary data for indicators linked to the societal impact of research, in addition to generating insights about the ‘pathway’ from research to societal impact. The indicators need to be ‘socially robust’ in the sense that their validation processes should include the research beneficiaries and their representatives. In doing so, RIS-Agric will produce a useful, standardised measurement mechanism that is aligned across the different commodities. The focus on productive interactions will be supplemented by other methods in order to enable the quantification of societal impact in the form of ‘impact scores’. (Author) 18. Sound Shell Model for Acoustic Gravitational Wave Production at a First-Order Phase Transition in the Early Universe Science.gov (United States) Hindmarsh, Mark 2018-02-01 A model for the acoustic production of gravitational waves at a first-order phase transition is presented. The source of gravitational radiation is the sound waves generated by the explosive growth of bubbles of the stable phase. The model assumes that the sound waves are linear and that their power spectrum is determined by the characteristic form of the sound shell around the expanding bubble. The predicted power spectrum has two length scales, the average bubble separation and the sound shell width when the bubbles collide. The peak of the power spectrum is at wave numbers set by the sound shell width. For a higher wave number k , the power spectrum decreases to k-3. At wave numbers below the inverse bubble separation, the power spectrum goes to k5. For bubble wall speeds near the speed of sound where these two length scales are distinguished, there is an intermediate k1 power law. The detailed dependence of the power spectrum on the wall speed and the other parameters of the phase transition raises the possibility of their constraint or measurement at a future space-based gravitational wave observatory such as LISA. 19. Sound Shell Model for Acoustic Gravitational Wave Production at a First-Order Phase Transition in the Early Universe. Science.gov (United States) Hindmarsh, Mark 2018-02-16 A model for the acoustic production of gravitational waves at a first-order phase transition is presented. The source of gravitational radiation is the sound waves generated by the explosive growth of bubbles of the stable phase. The model assumes that the sound waves are linear and that their power spectrum is determined by the characteristic form of the sound shell around the expanding bubble. The predicted power spectrum has two length scales, the average bubble separation and the sound shell width when the bubbles collide. The peak of the power spectrum is at wave numbers set by the sound shell width. For a higher wave number k, the power spectrum decreases to k^{-3}. At wave numbers below the inverse bubble separation, the power spectrum goes to k^{5}. For bubble wall speeds near the speed of sound where these two length scales are distinguished, there is an intermediate k^{1} power law. The detailed dependence of the power spectrum on the wall speed and the other parameters of the phase transition raises the possibility of their constraint or measurement at a future space-based gravitational wave observatory such as LISA. 20. Potential biogas production from sewage sludge: A case study of the sewage treatment plant at Kwame Nkrumah university of science and technology, Ghana Energy Technology Data Exchange (ETDEWEB) Arthur, Richard [Energy Systems Engineering Department, Koforidua Polytechnic, Box KF 981, Koforidua (Ghana); Brew-Hammond, Abeeku [Faculty of Mechanical and Agricultural Engineering, Kwame Nkrumah University of Science and Technology, Private Mail Bag, Kumasi (Ghana) 2010-07-01 Biogas generation is one of the most promising renewable energy sources in Ghana. Anaerobic digestion is one of the effective ways of generating biogas. Anaerobic digestion is also a reliable method for wastewater treatment and the digestion the effluent can be used as fertilizer to enhance the fertility of the soil. This paper looks at the possibility of constructing a biogas plant at the KNUST sewage treatment plant tapping its feedstock the sludge at the Primary Sedimentation Tank to generate biogas. A laboratory experiment was done to determine the faecal sludge quality. The flowrate of the sludge was estimated based on the number of times the penstocks (valves) are operated to desludge the sewage which also depends on whether the university is on vacation (35.72 m3/day) or in session (71.44 m3/day). These parameters were used to determine the biogas potential of the sewage using 10, 20 and 30 days retention time for plant sizes of 540 m3, 1100m3 and 1600 m3 respectively. It was estimated that 170,719 m3, 341,858 m3 and 419,458 m3 of methane can be produced in a year and the power production was estimated to be 50 kW, 100 kW and 120 kW for the 540 m3, 1100m3 and 1600 m3 digester sizes respectively. 1. MCNP5 evaluation of photoneutron production from the Alexandria University 15 MV Elekta Precise medical LINAC. Science.gov (United States) Abou-Taleb, W M; Hassan, M H; El Mallah, E A; Kotb, S M 2018-05-01 Photoneutron production, and the dose equivalent, in the head assembly of the 15 MV Elekta Precise medical linac; operating in the faculty of Medicine at Alexandria University were estimated with the MCNP5 code. Photoneutron spectra were calculated in air and inside a water phantom to different depths as a function of the radiation field sizes. The maximum neutron fluence is 3.346×10 -9 n/cm 2 -e for a 30×30 cm 2 field size to 2-4 cm-depth in the phantom. The dose equivalent due to fast neutron increases as the field size increases, being a maximum of 0.912 ± 0.05 mSv/Gy at depth between 2 and 4 cm in the water phantom for 40×40 cm 2 field size. Photoneutron fluence and dose equivalent are larger to 100 cm from the isocenter than to 35 cm from the treatment room wall. Copyright © 2018 Elsevier Ltd. All rights reserved. 2. Hupa Numbers.

A structural equation modeling of executive functions, IQ and mathematical skills in primary students: Differential effects on number production, mental calculus and arithmetical problems. Science.gov (United States) Arán Filippetti, Vanessa; Richaud, María Cristina 2017-10-01 Though the relationship between executive functions (EFs) and mathematical skills has been well documented, little is known about how both EFs and IQ differentially support diverse math domains in primary students. Inconsistency of results may be due to the statistical techniques employed, specifically, if the analysis is conducted with observed variables, i.e., regression analysis, or at the latent level, i.e., structural equation modeling (SEM). The current study explores the contribution of both EFs and IQ in mathematics through an SEM approach. A total of 118 8- to 12-year-olds were administered measures of EFs, crystallized (Gc) and fluid (Gf) intelligence, and math abilities (i.e., number production, mental calculus and arithmetical problem-solving). Confirmatory factor analysis (CFA) offered support for the three-factor solution of EFs: (1) working memory (WM), (2) shifting, and (3) inhibition. Regarding the relationship among EFs, IQ and math abilities, the results of the SEM analysis showed that (i) WM and age predict number production and mental calculus, and (ii) shifting and sex predict arithmetical problem-solving. In all of the SEM models, EFs partially or totally mediated the relationship between IQ, age and math achievement. These results suggest that EFs differentially supports math abilities in primary-school children and is a more significant predictor of math achievement than IQ level. 5. Sagan numbers OpenAIRE Mendonça, J. Ricardo G. 2012-01-01 We define a new class of numbers based on the first occurrence of certain patterns of zeros and ones in the expansion of irracional numbers in a given basis and call them Sagan numbers, since they were first mentioned, in a special case, by the North-american astronomer Carl E. Sagan in his science-fiction novel "Contact." Sagan numbers hold connections with a wealth of mathematical ideas. We describe some properties of the newly defined numbers and indicate directions for further amusement. 6.

Eulerian numbers CERN Document Server Petersen, T Kyle 2015-01-01 This text presents the Eulerian numbers in the context of modern enumerative, algebraic, and geometric combinatorics. The book first studies Eulerian numbers from a purely combinatorial point of view, then embarks on a tour of how these numbers arise in the study of hyperplane arrangements, polytopes, and simplicial complexes. Some topics include a thorough discussion of gamma-nonnegativity and real-rootedness for Eulerian polynomials, as well as the weak order and the shard intersection order of the symmetric group. The book also includes a parallel story of Catalan combinatorics, wherein the Eulerian numbers are replaced with Narayana numbers. Again there is a progression from combinatorics to geometry, including discussion of the associahedron and the lattice of noncrossing partitions. The final chapters discuss how both the Eulerian and Narayana numbers have analogues in any finite Coxeter group, with many of the same enumerative and geometric properties. There are four supplemental chapters throughout, ... 8. Transfinite Numbers Indian Academy of Sciences (India) Transfinite Numbers. What is Infinity? S M Srivastava.

Science Production in Germany, France, Belgium, and Luxembourg: Comparing the Contributions of Research Universities and Institutes to Science, Technology, Engineering, Mathematics, and Health. Science.gov (United States) Powell, Justin J W; Dusdal, Jennifer 2017-01-01 Charting significant growth in science production over the 20th century in four European Union member states, this neo-institutional analysis describes the development and current state of universities and research institutes that bolster Europe's position as a key region in global science. On-going internationalization and Europeanization of higher education and science has been accompanied by increasing competition as well as collaboration. Despite the policy goals to foster innovation and further expand research capacity, in cross-national and historical comparison neither the level of R&D investments nor country size accounts completely for the differential growth of scientific productivity. Based on a comprehensive historical database from 1900 to 2010, this analysis uncovers both stable and dynamic patterns of production and productivity in Germany, France, Belgium, and Luxembourg. Measured in peer-reviewed research articles collected in Thomson Reuters' Science Citation Index Expanded, which includes journals in the fields of Science, Technology, Engineering, Mathematics, and Health, we show the varying contributions of different organizational forms, especially research universities and research institutes. Comparing the institutionalization pathways that created the conditions necessary for continuous and strong growth in scientific productivity in the European center of global science emphasizes that the research university is the key organizational form across countries. 10. Evaluation of the production capabilities of 18F, 11C, 13N and 15O PET isotopes at the PET-cyclotron-radiochemistry site of Messina University Directory of Open Access Journals (Sweden) Lucrezia Auditore 2017-02-01 Full Text Available The production of 18F, 11C, 13N, and 15O positron emitting radionuclides for PET imaging is usually accomplished in Nuclear Medicine Departments through direct nuclear reactions induced by protons accelerated by compact medical cyclotrons on liquid or gaseous targets. Messina University has funded the construction of a PET-cyclotron-radio-chemistry plant at the Messina University Hospital, equipped with a 11 MeV self-shielded cyclotron. We estimated the expected production yields of these nuclides, accounting for target thickness, production of other radioactive nuclides, and time effects on the irradiated target purity. To this aim, both TALYS code (v. 1.8 and an analytical approach based on EXFOR experimental data were used. The general agreement between the two approaches, and with the available literature data, allows to assess the expected yields at the End of Bombardment, and relative target purities, to be used for further radiopharmaceutical preparation steps. 11.

Otherwise, the effect on N leaching and its risk were consistent across the studies conducted in different countries on clay and coarse-textured mineral soils with different ploughing times, N fertilization rates (50-160 kg/ ha), and amounts of annual precipitation (480-1040 mm). Non-legume catch crops reduced grain yield by 3% with no changes in grain N content. In contrast, legumes and mixed catch crops increased both grain yield and grain N content by 6%. In spring cereal production, undersown non-legume catch crops are deemed a universal and effective method for reducing N leaching loss across the various soils, management practices and weather conditions in the Nordic countries. The environmental benefits of using non-legume catch crops appear considerable compared to the adverse reduction in grain yields, amounting to only a few percent. Catch crops are advisable for fields at high risk for N leaching (e.g., sandy soils or soils and crops requiring high N fertilization). 14. The economical production of alcohol fuels from coal-derived synthesis gas. Quarterly technical progress report Number 8, 1 July, 1993--30 September, 1993 Energy Technology Data Exchange (ETDEWEB) 1993-10-01 Task 1, the preparation of catalyst materials, is proceeding actively. At WVU, catalysts based on Mo are being prepared using a variety of approaches to alter the oxidation state and environment of the Mo. At UCC and P, copper-based zinc chromite spinel catalysts will be prepared and tested. The modeling of the alcohol-synthesis reaction in a membrane reactor is proceeding actively. Under standard conditions, pressure drop in the membrane reactor has been shown to be negligible. In Task 2, base case designs had previously been completed with a Texaco gasifier. Now, similar designs have been completed using the Shell gasifier. A comparison of the payback periods or production cost of these plants shows significant differences among the base cases. However, a natural gas only design, prepared for comparison purposes, gives a lower payback period or production cost. Since the alcohol synthesis portion of the above processes is the same, the best way to make coal-derived higher alcohols more attractive economically than natural gas-derived higher alcohols is by making coal-derived syngas less expensive than natural gas-derived syngas. The maximum economically feasible capacity for a higher alcohol plant from coal-derived syngas appears to be 32 MM bbl/yr. This is based on consideration of regional coal supply in the eastern US, coal transportation, and regional product demand. The benefits of economics of scale are illustrated for the base case designs. A value for higher alcohol blends has been determined by appropriate combination of RVP, octane number, and oxygen content, using MTBE as a reference. This analysis suggests that the high RVP of methanol in combination with its higher water solubility make higher alcohols more valuable than methanol. 15. [Human papilloma virus and Chlamydia trachomatis by number of sexual partners and time of sexual activity on university students in the Region of La Araucanía, Chile]. Science.gov (United States) Melo, Angélica; Lagos, Nicole; Montenegro, Sonia; Orellana, Juan José; Vásquez, Ana María; Moreno, Sergio; Liempi, Sandra; Guzmán, Pablo; Fonseca-Salamanca, Flery 2016-06-01 Human papilloma virus (HPV) and Chlamydia trachomatis are the most prevalent sexually transmitted infections (STIs), among teenagers and young people, with risk factors: active sex life and multiple partners. Chlamydia trachomatis infection may favor HPV infection and this, the development of cervical cancer. Both infections can lead to consequences on sexual and reproductive health. To determine frequency of HPV and C. trachomatis in asymptomatic university women less than 25 years, associating them with number of sexual partners (n°SxP) and time of sexual activity (TSxA). Material andMethods: 151 cervical samples for HPV and C. trachomatis, were processed by conventional and in real time reaction polymerase chain. HPV 21, 8%, C. trachomatis 11, 2% and co-infection (HPV/C.trachomatis), 4.6%. Aimong HPV +, 80, 6% showed high risk HPV. The n°SxP was strongly associated with HPV. Aimong young coinfected HPV/C. trachomatis, 71.4% had 3 or more PSx. Chlamydia trachomatis was more frequent (64,7%) that HPV within range of 3-5 years according to the TSxA, Discussion: A high prevalence of HPV and C. trachomatis was observed. Young women with coinfection HPV/C. trachomatis could be a high-risk group need to monitor their infections. It suggests the implementation of university programs in education, counseling and prevention in sexual health. 16. INVESTIGATING THE EFFECTS OF PHYSICAL ACTIVITY LEVELS, DAIRY PRODUCTS AND CALCIUM INTAKES ON RISK FACTORS OF OSTEOPOROSIS PREVENTION IN FEMALE STUDENTS OF ISLAMIC AZAD UNIVERSITY OF DAMAVAND, IRAN Directory of Open Access Journals (Sweden) Rehmani Ghobadi Marya 2014-11-01 Full Text Available Aim: Osteoporosis is a serious metabolic bone disorder that often results in hip fracture and usually asymptomatic in its initial stages. Since the majority of bone formation occurs during childhood and adolescence, it is important to begin primary prevention at an early age, although the optimal way for instilling this preventive behavior in youth has not yet been defined. The purpose of this study was to investigating the effects of physical activity levels, dairy products and calcium intakes on risk factors of osteoporosis prevention in female students of Islamic Azad university of Damavand in Iran. Methods: This cross sectional study was conducted on 280 healthy female university students aged between 18 to 24 years old who were selected randomly from the university students of Islamic Azad university of Damavand, Iran. Subjects completed an informed consent form, health history questionnaire; food questionnaire was used to assess the entire dietary component intakes and physical activity questionnaire (Baecke. Result: The result shows that Increase in physical activity and diary product consumption, the calcium intake with a decrease in BMI, and increase in BMD. Also results shows that there were significant negative correlations between the physical activity levels, diary product consumption, the calcium intake and risk factors of osteoporosis. Conclusions: Increased physical activity and diary product consumption, the calcium intake is associated with an increase in BMD and a concomitant decrease in BMI. These findings suggest that population-level interventions to increase physical activity and diary product consumption, the calcium intake would favorably impact bone and other health outcomes. Thus, dietary pattern coupled with higher education levels and greater physical activity favored bone health and osteoporosis prevention in middle school females. 17.

Funny Numbers Directory of Open Access Journals (Sweden) Theodore M. Porter 2012-12-01 Full Text Available The struggle over cure rate measures in nineteenth-century asylums provides an exemplary instance of how, when used for official assessments of institutions, these numbers become sites of contestation. The evasion of goals and corruption of measures tends to make these numbers “funny” in the sense of becoming dis-honest, while the mismatch between boring, technical appearances and cunning backstage manipulations supplies dark humor. The dangers are evident in recent efforts to decentralize the functions of governments and corporations using incen-tives based on quantified targets. 19. Transcendental numbers CERN Document Server Murty, M Ram 2014-01-01 This book provides an introduction to the topic of transcendental numbers for upper-level undergraduate and graduate students. The text is constructed to support a full course on the subject, including descriptions of both relevant theorems and their applications. While the first part of the book focuses on introducing key concepts, the second part presents more complex material, including applications of Baker’s theorem, Schanuel’s conjecture, and Schneider’s theorem. These later chapters may be of interest to researchers interested in examining the relationship between transcendence and L-functions. Readers of this text should possess basic knowledge of complex analysis and elementary algebraic number theory. 20. Profiling of Biomarkers for the Exposure of Polycyclic Aromatic Hydrocarbons: Lamin-A/C Isoform 3, Poly[ADP-ribose] Polymerase 1, and Mitochondria Copy Number Are Identified as Universal Biomarkers Directory of Open Access Journals (Sweden) Hwan-Young Kim 2014-01-01 Full Text Available This study investigated the profiling of polycyclic aromatic hydrocarbon- (PAH- induced genotoxicity in cell lines and zebrafish. Each type of cells displayed different proportionality of apoptosis. Mitochondrial DNA (mtDNA copy number was dramatically elevated after 5-day treatment of fluoranthene and pyrene. The notable deregulated proteins for PAHs exposure were displayed as follows: lamin-A/C isoform 3 and annexin A1 for benzopyrene; lamin-A/C isoform 3 and DNA topoisomerase 2-alpha for pentacene; poly[ADP-ribose] polymerase 1 (PARP-1 for fluoranthene; and talin-1 and DNA topoisomerase 2-alpha for pyrene. Among them, lamin-A/C isoform 3 and PARP-1 were further confirmed using mRNA and protein expression study. Obvious morphological abnormalities including curved backbone and cardiomegaly in zebrafish were observed in the 54 hpf with more than 400 nM of benzopyrene. In conclusion, the change of mitochondrial genome (increased mtDNA copy number was closely associated with PAH exposure in cell lines and mesenchymal stem cells. Lamin-A/C isoform 3, talin-1, and annexin A1 were identified as universal biomarkers for PAHs exposure. Zebrafish, specifically at embryo stage, showed suitable in vivo model for monitoring PAHs exposure to hematopoietic tissue and other organs. 1.

The Effect of Learning Strategies Instruction on the Oral Production Development of English Undergraduate Students from the Federal University of Pará: A Case Study Directory of Open Access Journals (Sweden) Kelly C. M. Gaignoux 2011-07-01 Full Text Available This study aims at investigating how learning strategies instruction may enhance the development of oral production. Instruments used to conduct this case study were field notes, questionnaires, interviews and class audio recordings. Seven female third level undergraduate students of the Curso de Letras of the Federal University of Pará were the subjects of this study. Since the oral production is the main concern of most foreign language learners, this investigation aims at contributing to a better understanding of this issue by suggesting that the explicit learning strategies teaching may conduct to more satisfactory outcomes. Results showed that there were changes in the learning strategies repertoire used by participants. 5. Assessment of Predictable Productivity of Nurses Working in Kerman University of Medical Sciences' Teaching Hospitals via the Dimensions of Quality of Work Life. Science.gov (United States) Borhani, Fariba; Arbabisarjou, Azizollah; Kianian, Toktam; Saber, Saman 2016-10-01 Despite the existence of a large community of nurses, specific mechanisms have not been developed yet to consider their needs and the quality of their work life. Moreover, few studies have been conducted to analyze the nature of nursing, nursing places or nurses' quality of work life. In this regard, the present study aimed to assess predictable productivity of nurses working in Kerman University of Medical Sciences' teaching hospitals via the dimensions of Quality of Work Life. The present descriptive-correlational study was conducted to assess predictable productivity of nurses via the dimensions of Quality of Work Life. The study's population consisted of all nurses working in different wards of teaching hospitals associated with Kerman University of Medical Sciences. Out of the whole population, 266 nurses were selected based on the simple random sampling method. To collect data, the questionnaires of 'Quality of Nursing Work Life' and 'Productivity' were used after confirming their reliability (test-retest) and content validity. Finally, the collected data were analyzed through the SPSS software (version 16). Although the quality of work life for nurses was average and their productivity was low but the results showed that quality of life is directly related to nurses' productivity. Quality of life and its dimensions are predictive factors in the in the nurses' productivity. It can conclude that by recognizing the nurses' quality of work life situation, it can realize this group productivity and their values to the efficiency of the health system. For the quality of working life improvement and increasing nurses' productivity more efforts are needed by authorities. The findings can be applied by managers of hospitals and nursing services along with head nurses to enhance the quality of health services and nursing profession in general. 6. Baby universes International Nuclear Information System (INIS) Strominger, A. 1988-01-01 This paper discusses how the subject of baby universes and their effects on spacetime coupling constants is in its infancy and rapidly developing. The subject is based on the non-existent (even by physicists' standards) Euclidean formulation of quantum gravity, and it is therefore necessary to make a number of assumptions in order to proceed. Nevertheless, the picture which has emerged is quite appealing: all spacetime coupling constants become dynamical variables when the effects of baby universes are taken into account. This fact might even solve the puzzle of the cosmological constant. The subject therefore seems worth further investigation 7. Evaluation of scientific output in Dentistry in Spanish Universities. Science.gov (United States) De la Flor-Martínez, M; Galindo-Moreno, P; Sánchez-Fernández, E; Abadal, E; Cobo, M-J; Herrera-Viedma, E 2017-07-01 The aim of this study was to assess the scientific output of Spanish universities that offer a bachelor's degree in dentistry through the use of various bibliometric indicators. A total of 21 universities offered a bachelor's degree in dentistry in academic year 2016-2017. The search for papers published by authors associated with these institutions was carried out using the selection of journals listed in the Journal Citation Reports (JCR) and the Web of Knowledge database for the period 1986-2017. On the basis of these data, we determined the output, the h-, g- and hg-indexes, the most productive authors, international collaborations, and the most relevant journals. Public universities obtained better results than private universities. The University of Valencia was ranked first, followed by the Complutense University of Madrid and the University of Granada. The most productive author was José Vicente Bagán, but the author with the highest h-index was Mariano Sanz and Manuel Toledado. The universities with the greatest output and highest citation rates had more international collaborations. The most developed fields in Spanish universities were Oral surgery, Oral medicine and Dental materials. The universities had different models of production. At universities such as Barcelona or Valencia, the production was focused on very few departments and authors. At the other extreme, the University of Granada had various sources of research and authors, which meant that its output and citation rate could increase more. University faculties must provide suitable academic and research training, and therefore must be assessed using objective criteria and bibliometric tools. Although the number of university schools and faculties that teach dentistry has increased, and particularly the number of private universities, there is no correlation between their quality and output and the number of places offered on their courses. 8.

Science.gov (United States) Faciola, A P; Broderick, G A 2014-01-01 The objectives of this study were to evaluate the feeding of coconut oil (CO), in which lauric acid (La) comprises about 50% of the fatty acid composition, as a practical rumen protozoa (RP) suppressing agent, to assess whether the source of La affects ruminal fermentation and animal performance and to test whether suppressing RP improves N utilization, nutrient digestion, nutrient flow at the omasal canal, and milk production. Fifteen multiparous Holstein cows (3 fitted with ruminal cannulas) and 15 primiparous Holstein cows (3 fitted with ruminal cannulas) were used in a replicated 3×3 Latin square experiment with 14d of adaptation and 14d of sample collection. Diets were fed as total mixed ration and contained (dry matter basis) 10% corn silage, 50% alfalfa silage, and 40% concentrate. The control diet contained 3% (dry matter basis) calcium soaps of palm oil fatty acids (Megalac, Church & Dwight Co. Inc., Princeton, NJ) as a ruminally inert fat source and had no added La or CO. Diets with La and CO were formulated to contain equal amounts of La (1.3%, dry matter basis). Dry matter intake was not affected by treatment. Both CO and La reduced RP numbers by about 40%. Lauric acid reduced yield of milk and milk components; however, CO did not affect yield of milk and yields of milk components. Both La and CO caused small reductions in total VFA concentration; CO increased molar proportion of ruminal propionate, reduced ruminal ammonia and branched-chain volatile fatty acids, suggesting reduced protein degradation, and reduced milk urea N and blood urea N concentrations, suggesting improved protein efficiency. Lauric acid reduced total-tract apparent digestibility of neutral detergent fiber and acid detergent fiber as well as ruminal apparent digestibility of neutral detergent fiber and acid detergent fiber as measured at the omasal canal; however, CO did not alter fiber digestion. Microbial protein flow at the omasal canal, as well as the flow of N fractions at 11. Universal methods of creation of functionally developed management systems of special purpose of industrial enterprises and production associations and their use when planning and introducing the subsystem of accounting and analytical support Directory of Open Access Journals (Sweden) Tkachenko Sergіy A. 2013-03-01 Full Text Available The goal of the article lies in formation of a paradigm (sample of universal methods of creation of functionally developed management systems of special purpose of industrial enterprises and production associations and their use when planning and introducing the subsystem of accounting and analytical support. Analysing, systemising and generalising scientific works of many economists, the article describes ways of solution of the problem of organisation of works on planning and introducing the accounting function at industrial enterprises and in production associations – individual planning, increase of a number of organisations that plan functionally developed accounting subsystem and training of relevant specialists. In the result of the study the article realises an important direction of development in improvement of organisation of accounting and economic and analytical support at industrial enterprises and in production associations based on uniformity of project decisions on the subsystem of the accounting and analytical support and functional development of the process of its creation. The issue of organisation of the calculation process while planning and introducing the accounting function in functionally developed management systems of special purpose of industrial enterprises and production associations is of special urgency among the prospects of further studies in this direction. Further development of accounting can result in replacement of traditional accounting with functionally developed subsystem of accounting and analytical support with intensive use of the concept of methodologically justified paradigmatic approach. 12. Fragment production in central heavy-ion collisions: reconciling the dominance of dynamics with observed phase transition signals through universal fluctuations International Nuclear Information System (INIS) Frankland, J.D.; Chbihi, A.; Hudan, S. 2002-01-01 Fragment production in central collisions of Xe+Sn has been systematically studied with the INDRA multidetector from 25 to 150 AMeV. The predominant role of collision dynamics is evidenced in multiple intermediate mass fragment production even at the lowest energies, around the so-called multifragmentation threshold. For beam energies 50 AMeV and above, a promising agreement with suitably modified Anti-symmetrized Molecular Dynamics calculations has been achieved. Intriguingly the same reactions have recently been interpreted as evidence for a liquid-gas phase transition in thermodynamically equilibrated systems. The universal fluctuation theory, thanks to its lack of any equilibrium hypothesis, shows clearly that in all but a tiny minority of carefully-selected central collisions fragment production is incompatible with either critical or phase coexistence behaviour. On the other hand, it does not exclude some similarity with aggregation scenarios such as the lattice-gas or Fisher droplet models. (authors) 13.

Plasma universe International Nuclear Information System (INIS) Alfven, H. 1986-04-01 Traditionally the views in our cosmic environment have been based on observations in the visual octave of the electromagnetic spectrum, during the last half-century supplemented by infrared and radio observations. Space research has opened the full spectrum. Of special importance are the X-ray-gamma-ray regions, in which a number of unexpected phenomena have been discovered. Radiations in these regions are likely to originate mainly from magnetised cosmic plasma. Such a medium may also emit synchrotron radiation which is observable in the radio region. If we try to base a model of the universe on the plasma phenomena mentioned we find that the plasma universe is drastically different from the traditional visual universe. Information about the plasma universe can also be obtained by extrapolation of laboratory experiments and magnetospheric in situ measurements of plasma. This approach is possible because it is likely that the basic properties of plasma are the same everywhere. In order to test the usefulness of the plasma universe model we apply it to cosmogony. Such an approach seems to be rather successful. For example, the complicated structure of the Saturnian C ring can be accounted for. It is possible to reconstruct certain phenomena 4-5 bilions years ago with an accuracy of better than 1 percent 16.

Número de ramos plagiotrópicos e produtividade de duas cultivares de cafeeiro utilizando irrigação por gotejamento Number of primary branches and productivity of two cultivars of coffee using drip irrigation Directory of Open Access Journals (Sweden) André Ribeiro da Costa 2010-12-01 number of plagiotropic branches and in the productivity of the cultivars of coffee Obatã and IAPAR - 59. The seedlings were planted in the spacing of 2.0 meters between lines and 1.0 meter within lines, characterizing a dense system. In this experiment was used the system of localized irrigation by dripping. The experiment followed a design completely randomized in split plots with four replications. The plots and subplots were composed by percentages of doses of NPK and crops, respectively. The interaction between those factors influenced significantly the productivity and the number of plagiotropic branches allowing concluding which dose of fertilizer is indicated for each cultivation. The maximum yield to grow Obatã was achieved with doses of NPK percentages of 119.5%, 151.25% and 154.17% for non-irrigated crops, irrigated and fertilized, respectively. The maximum yield for IAPAR - 59 in nonirrigated crops, irrigated and fertilized was achieved with doses of NPK percentages of 137.83%, 162% and 151.75% respectively. Regarding the number of primary branches the best dose for cultivating crops in irrigated and Obatã fertirrigated corresponded to a percentage of 200%, while the percentage dose of 150% showed the most suitable for IAPAR - 59 for the irrigated crops. The best productive was obtained for the fertirrigated cultivations. 18. Estimation of Time-Dependent Reproduction Numbers for Porcine Reproductive and Respiratory Syndrome across Different Regions and Production Systems of the US. Science.gov (United States) Arruda, Andréia G; Alkhamis, Moh A; VanderWaal, Kimberly; Morrison, Robert B; Perez, Andres M 2017-01-01 Porcine reproductive and respiratory syndrome (PRRS) is, arguably, the most impactful disease for the North American swine industry, due to its known considerable economic losses. The Swine Health Monitoring Project (SHMP) monitors and reports weekly new PRRS cases in 766 sow herds across the US. The time-dependent reproduction number (TD-R) is a measure of a pathogen's transmissibility. It may serve to capture and report PRRS virus (PRRSV) spread at the regional and system levels. The primary objective of the study here was to estimate the TD-R values for PRRSV using regional and system-level PRRS data, and to contrast it with commonly used metrics of disease, such as incidence estimates and space-time clusters. The second objective was to test whether the estimated TD-Rs were homogenous across four US regions. Retrospective monthly incidence data (2009-2016) were available from the SHMP. The dataset was divided into four regions based on location of participants, and demographic and environmental features, namely, South East (North Carolina), Upper Midwest East (UME, Minnesota/Iowa), Upper Midwest West (Nebraska/South Dakota), and South (Oklahoma panhandle). Generation time distributions were fit to incidence data for each region, and used to calculate the TD-Rs. The Kruskal-Wallis test was used to determine whether the median TD-Rs differed across the four areas. Furthermore, we used a space-time permutation model to assess spatial-temporal patterns for the four regions. Results showed TD-Rs were right skewed with median values close to "1" across all regions, confirming that PRRS has an overall endemic nature. Variation in the TD-R patterns was noted across regions and production systems. Statistically significant periods of PRRSV spread (TD-R > 1) were identified for all regions except UME. A minimum of three space-time clusters were detected for all regions considering the time period examined herein; and their overlap with "spreader events" identified by 19. A bibliometric analysis of leading universities in innovation research Directory of Open Access Journals (Sweden) Christian A. Cancino 2017-09-01 Full Text Available The number of innovation studies with a management perspective has grown considerably over the last 25 years. This study identified the universities that are most productive and influential in innovation research. The leading innovation research journals were also studied individually to identify the most productive universities for each journal. Data from the Web of Science were analyzed. Studies that were published between 1989 and 2013 were filtered first by the keyword “innovation” and second by 18 management-related research areas. The results indicate that US universities are the most productive and influential because they account for the most publications with a high number of citations and high h-index. Following advances in the productivity of numerous European journals, however, universities from the UK and the Netherlands are the most involved in publishing in journals that specialize in innovation research. 20. An Investigation of Scientific Production of Executive Secretariat Graduates At the Federal University of Ceará From 2010 to 2015 Directory of Open Access Journals (Sweden) Márcia Monalisa Garcia 2017-05-01 Full Text Available The culture of research in Executive Secretary course is recent and has been widely promoted in the academic and scientific community. Therefore, this study aims to analyze the scientific production of graduates from the Executive Secretariat Course at the Federal University of Ceará (UFC from 2010 to 2015, in order to verify their contributions to the increase of scientific production in the field. In order to achieve the proposed objectives, a descriptive, bibliographic research was carried out with quantitative and qualitative approach, using as basis for data analysis a review on the content "Productions" of the Brazilian database résumé (Curriculum Lattes, of UFC graduates since the foundation of the course in 1995, to the year 2015. Among the main results, the research pointed out the need for diversification on the types of scientific contribution, since most of it has focused on paper presentations; also diversifying the researched topics, since most of them focused on professional practice, highlighting the focus on the technicist character of this profession. There has also been a significant increase in scientific production in the years 2013 and 2014. This work has raised the importance of spreading a new mentality about the secretarial studies, stimulating the production of new knowledge in this field. 1.

Funding was approved in July of 1999 and received by participating Mississippi institutions by 2000. The project was funded via two 3-year phases of operation (the second phase was awarded based on the high merits observed from the first 3-year phase), with funding ending in 2007. The mission of the Consortium was to promote the utilization of biomass, both cultured and waste derived, for the production of commodity and specialty chemicals. These scientific efforts, although generally basic in nature, are key to the development of future industries within the Southeastern United States. In this proposal, the majority of the efforts performed under the DOE EPSCoR funding were focused primarily toward the production of ethanol from lignocellulosic feedstocks and biogas from waste products. However, some of the individual projects within this program investigated the production of other products from biomass feeds (i.e. acetic acid and biogas) along with materials to facilitate the more efficient production of chemicals from biomass. Mississippi is a leading state in terms of raw biomass production. Its top industries are timber, poultry production, and row crop agriculture. However, for all of its vast amounts of biomass produced on an annual basis, only a small percentage of the biomass is actually industrially produced into products, with the bulk of the biomass being wasted. This situation is actually quite representative of many Southeastern US states. The research and development efforts performed attempted to further develop promising chemical production techniques that use Mississippi biomass feedstocks. The three processes that were the primary areas of interest for ethanol production were syngas fermentation, acid hydrolysis followed by hydrolyzate fermentation, and 2. ANNALS OF THE UNIVERSITY OF ORADEA FASCICLE OF TEXTILES, LEATHERWORK 133 DETERMINANTS TO THE CONSUMPTION OF LEATHER PRODUCTS Directory of Open Access Journals (Sweden) CARRIER Serge A. 2014-05-01 Full Text Available The current paper looks at some of the determinants in the consumption of leather fashion products by the 16-34 year old population of Québec. Although the Québec population presents some idiosyncrasies, we surmise that our results could probably be generalized to similarly aged population groups in the western world. Leather goods are now often considered as luxury it ems, a sub-sector of the fashion industry which has been outgrowing all others in the last few years. Yet leather is often seen as non-ethical, requiring the killing of animals, and non-ecological, since the production process is polluting. Those two opposing forces make the future of leather very uncertain. Surprisingly, very little literature has been written on the subject. This paper presents a survey in which the authors tried to identify the determinants to the consumption of leather in the 16-34 age groups, often referred to as Generation Y. Our findings reflect this dichotomy between the consumer’s interest for apparel and his or her negative reaction to some characteristics of leather. Although not as influenced as fur by ethical and ecological concerns, leather products the object of similar reactions. This paper concludes on some recommendations to participants in the leather industry who should note this trend and try to position their products in such a way as to minimize the negative elements and bank on the more positive aspects. 3.

Radiation Science and Engineering Center 2013-08-15 The Penn State Breazeale Nuclear Reactor (PSBR) at the Radiation Science and Engineering Center (RSEC) has produced radioisotopes for research and commercial purposes since 1956. With the rebirth of the radiochemistry education and research program at the RSEC, the Center stands poised to produce a variety of radioisotopes for research and industrial work that is in line with the mission of the DOE Office of Science, Office of Nuclear Physics, Isotope Development and Production Research and Application Program. The RSEC received funding from the Office of Science in 2010 to improve production techniques and develop new capabilities. Under this program, we improved our existing techniques to provide four radioisotopes (Mn-56, Br-82, Na-24, and Ar-41) to researchers and industry in a safe and efficient manner. The RSEC is also working to develop new innovative techniques to provide isotopes in short supply to researchers and others in the scientific community, specifically Cu-64 and Cu-67. Improving our existing radioisotopes production techniques and investigating new and innovative methods are two of the main initiatives of the radiochemistry research program at the RSEC. 10.

Such parameters include cross sections, decay constants, branching ratios, fission yields, flux and time. The formulae are applied to isotopes of the Antimony, Tellurium, Iodine and Xenon series. The agreement between analytically obtained data and that derived from a computer evaluated model is good, suggesting that the analytical representation includes all the important parameters useful to the evaluation of the fission product concentrations 12. Universal mortality law and immortality Science.gov (United States) Azbel', Mark Ya. 2004-10-01 Well-protected human and laboratory animal populations with abundant resources are evolutionarily unprecedented. Physical approach, which takes advantage of their extensively quantified mortality, establishes that its dominant fraction yields the exact law, which is universal for all animals from yeast to humans. Singularities of the law demonstrate new kinds of stepwise adaptation. The law proves that universal mortality is an evolutionary by-product, which at any given age is reversible, independent of previous life history, and disposable. Life expectancy may be extended, arguably to immortality, by minor biological amendments in the animals. Indeed, in nematodes with a small number of perturbed genes and tissues it increased 6-fold (to 430 years in human terms), with no apparent loss in health and vitality. The law relates universal mortality to specific processes in cells and their genetic regulation. 13. Universal kinematic scaling as a probe of factorized long-distance effects in high-energy quarkonium production Energy Technology Data Exchange (ETDEWEB) Faccioli, Pietro; Seixas, Joao [LIP and IST, Lisbon (Portugal); Lourenco, Carlos; Araujo, Mariana [CERN, Geneva (Switzerland) 2018-02-15 Dimensional analysis reveals general kinematic scaling rules for the momentum, mass, and energy dependence of Drell-Yan and quarkonium cross sections. Their application to mid-rapidity LHC data provides strong experimental evidence supporting the validity of the factorization ansatz, a cornerstone of non-relativistic QCD, still lacking theoretical demonstration. Moreover, data-driven patterns emerge for the factorizable long-distance bound-state formation effects, including a remarkable correlation between the S-wave quarkonium cross sections and their binding energies. Assuming that this scaling can be extended to the P-wave case, we obtain precise predictions for the not yet measured feed-down fractions, thereby providing a complete picture of the charmonium and bottomonium feed-down structure. This is crucial information for quantitative interpretations of quarkonium production data, including studies of the suppression patterns measured in nucleus-nucleus collisions. (orig.) 14.

We recently suggested that a low copy number at the AMY1 gene, associated with lower enzyme levels, also increases susceptibility to obesity. To advance our understanding of the effect of AMY1 copy number variation on metabolism, we compared the metabolomic signatures of high– and low–copy number carriers. We analyzed, using mass spectrometry and nuclear magnetic resonance (NMR), the sera of healthy normal-weight women carrying either low–AMY1 copies (LAs: four or fewer copies; n = 50) or high–AMY1 copies (HAs: eight or more copies; n = 50). Best-fitting multivariate models (empirical P < 1 ×$10^{−3})of mass spectrometry and NMR data were concordant in showing differences in lipid metabolism between the two groups. In particular, LA carriers showed lower levels of long- and medium-chain fatty acids, and higher levels of dicarboxylic fatty acids and 2-hydrox... 19. Productivity DEFF Research Database (Denmark) Spring, Martin; Johnes, Geraint; Hald, Kim Sundtoft Productivity is increasingly critical for developed economies. It has always been important: as Paul Krugman puts it, “Productivity isn’t everything, but in the long run it is almost everything. A country’s ability to improve its standard of living over time depends almost entirely on its ability...... to raise its output per worker”(Krugman, 1994). Analyses of productivity have, by and large, been the preserve of economists. Operations Management (OM) is rooted in a similar concern for the efficient use of scarce resources; Management Accounting (MA) is concerned with the institutionalised measurement...... and management of productivity. Yet the three perspectives are rarely connected. This paper is a sketch of a literature review seeking to identify, contrast and reconcile these three perspectives. In so doing, it aims to strengthen the connections between policy and managerial analyses of productivity.... 20. Knowledge about, attitude toward, and practice of skin lightening products use and its social correlates among university students in five Association of Southeast Asian Nations (ASEAN) countries. Science.gov (United States) Peltzer, Karl; Pengpid, Supa 2017-03-01 The aim of this study was to investigate the knowledge about, attitude toward, and use of skin lightening products (SLP) and its social and psychological correlates among university students from five Association of Southeast Asian Nations (ASEAN) countries. In a cross sectional survey, 3259 undergraduate university students (Mean age = 20.5 years, SD = 1.6) from five ASEAN countries responded to an anonymous questionnaire. Multivariate logistic regression analysis was used to identify associations between sociodemographic characteristics, knowledge, attitude, poor mental health, and SLP use. Overall, 79.1% of the students were aware that the use of SLP can harm the skin, and 30.1% knew the active ingredients of SLP. Most students had a positive perception of having a lighter skin tone and SLP. Overall, the prevalence of SLP use over the past 12 months was 30.7%, 16.7% of male, and 30.0% of female students, ranging from 13.4% in Myanmar to 69.4% in Thailand. In multivariate logistic regression analysis, among women, older age, coming from a poorer family, residing in an upper middle income country, awareness of active skin lightening ingredients, and poor mental health were associated with SLP, while among men, not aware of the negative effects of SLP and awareness of active skin lightening ingredients and poor mental health were associated with SLP use. A high prevalence of SLP use was found in a large sample of ASEAN university students, and several social and mental health-related risk factors were found that may help in guiding interventions. © 2017 The International Society of Dermatology. 1. Proceedings of JSPS-CAS Core University Program seminar on production and steady state confinement of high performance plasmas in magnetic confinement systems International Nuclear Information System (INIS) Wan Baonian; Toi, Kazuo 2005-09-01 The JSPS-CAS Core University Program (CUP) seminar on 'Production and steady-state confinement of high performance plasmas in magnetic confinement systems' was held from 27 July to 29 July 2005 in Institute of Plasma Physics, the Chinese Academy of Sciences, Hefei, China. This seminar was organized in the framework of CUP in the field of plasma and nuclear fusion. About 50 persons including 20 Japanese attendees attended this seminar. Long time sustainment of high confinement and high beta plasmas is crucial for realization of an advanced nuclear fusion reactor. This seminar was motivated to summarize the results of CUP obtained in four years activities of CUP, and to extract crucial issues to be resolved near future, which must drive near and mid- term collaborations in the framework of CUP.

Mathematics at University DEFF Research Database (Denmark) Winsløw, Carl 2015-01-01 Mathematics is studied in universities by a large number of students. At the same time it is a field of research for a (smaller) number of university teachers. What relations, if any, exist between university research and teaching of mathematics? Can research “support” teaching? What research...... and what teaching? In this presentation we propose a theoretical framework to study these questions more precisely, based on the anthropological theory of didactics. As a main application, the links between the practices of mathematical research and university mathematics teaching are examined... 3. Universal bounds on current fluctuations. Science.gov (United States) Pietzonka, Patrick; Barato, Andre C; Seifert, Udo 2016-05-01 For current fluctuations in nonequilibrium steady states of Markovian processes, we derive four different universal bounds valid beyond the Gaussian regime. Different variants of these bounds apply to either the entropy change or any individual current, e.g., the rate of substrate consumption in a chemical reaction or the electron current in an electronic device. The bounds vary with respect to their degree of universality and tightness. A universal parabolic bound on the generating function of an arbitrary current depends solely on the average entropy production. A second, stronger bound requires knowledge both of the thermodynamic forces that drive the system and of the topology of the network of states. These two bounds are conjectures based on extensive numerics. An exponential bound that depends only on the average entropy production and the average number of transitions per time is rigorously proved. This bound has no obvious relation to the parabolic bound but it is typically tighter further away from equilibrium. An asymptotic bound that depends on the specific transition rates and becomes tight for large fluctuations is also derived. This bound allows for the prediction of the asymptotic growth of the generating function. Even though our results are restricted to networks with a finite number of states, we show that the parabolic bound is also valid for three paradigmatic examples of driven diffusive systems for which the generating function can be calculated using the additivity principle. Our bounds provide a general class of constraints for nonequilibrium systems. 4. Influence of different combinations of cultivation techniques and a number of ameliorants on radiocesium contents in crop products grown in meadows International Nuclear Information System (INIS) Bystritskij, V.S.; Klimov, O.V.; Karnafel', P.V.; Kostyushko, P.V. 1992-01-01 The investigations have been performed at the meadows where soils are sandy, sod-podzolic, the area under investigation being the zone of strict radiation monitoring. The density of soil contamination with radiocesium was 20-25 Ci/sq.km. 4 cultivation techniques and 6 procedures of soil amelioration have been studied. It has been proved that Cs-134, -137 content reduces by a factor of 3.0 to 3.5 under conditions of standard plowing (down to 18 to 20 cm) and by a factor of 5 to 6 under conditions of deep plowing (down to 35 to 40 cm). For deep plowing when radiocontaminated sward was buried, radionuclide accumulation in crop products reduces by a factor of 1.5 as compared to standard plowing. When burial of radiocontaminated sward mixed with peat was provided, the radionuclide content has reduced by a factor of 2.0 to 2.5. When the radiocontaminated sword mixed with potassium chloride and lime was buried, the radionuclide content in crop products has reduced by a factor of 3. 5 tabs 5. Universal Alienation Directory of Open Access Journals (Sweden) David Harvey 2018-05-01 Full Text Available This article is part of a debate between David Harvey, Michael Hardt and Toni Negri. It takes Marx’s bicentenary as occasion for an update of his concept of alienation. The paper asks: how are we to interpret universal alienation and from whence does it come? Marx radically reformulated the concept of alienation in the Grundrisse. The humanism of the early Marx can be re-rooted and reconceptualised in the scientific mode proposed in the Grundrisse. In the Grundrisse, the universality of alienation is specific to capitalism’s historical evolution. Today, alienation exists almost everywhere. It exists at work in production, at home in consumption, and it dominates much of politics and daily life. Such trends intensify through the application of information technologies and artificial intelligence. Widespread alienation has resulted in Occupy movements as well as right-wing populism and bigoted nationalist and racist movements. Donald Trump is the President of alienation. The circulation of capital as totality consists of the three key moments of production, circulation and distribution. A lot of contemporary economic struggles are now occurring at the point of realisation rather than at the point of production. Protests are therefore today often expressions of broad-based discontent. Our future is dictated by the need to redeem our debts. Under such conditions democracy becomes a sham. The big question is what forms of social movement can help us get out of the state-finance nexus. The theory of objective alienation along with an understanding of its subjective consequences is one vital key to unlock the door of a progressive politics for the future. 6. Development of special machines for production of large number of superconducting coils for the spool correctors for the main dipole of LHC International Nuclear Information System (INIS) Puntambekar, A.M.; Karmarkar, M.G. 2003-01-01 Superconducting (Sc) spool correctors of different types namely Sextupole, (MCS) Decapole (MCD) and Octupole (MCO) are incorporated in each of the main dipole of Large Hadron Collider (LHC). In all 2464 MCS and 1232 MCDO magnets are required to equip all 1232 Dipoles of LHC. The coils wound from thin rectangular section Sc wires are the heart of magnet assembly and its performance for the field quality and cold quench training largely depends on the precise and robust construction of these coils. Under DAE-CERN collaboration CAT was entrusted with the responsibility of making these magnets for LHC. Starting with development of manual fixtures and prototyping using soldering, a more advances special Automatic Coils Winding and Ultrasonic Welding (USW) system for production of large no. of coils and magnets were built at CAT. The paper briefly describes the various developments in this area. (author) 7. Effects of calcium propionate by different numbers of applications in first week postpartum of dairy cows on hypocalcemia, milk production and reproductive disorders Directory of Open Access Journals (Sweden) Arda Kovanlıkaya 2010-01-01 Full Text Available This study was conducted to evaluate effects of calcium propionate on hypocalcemia, dry matter intake, body condition score, milk production and reproductive disorders in dairy cows. Twenty four multiparous Holstein cows were sorted by parity, body condition score (BCS in close-up period and season of calving and assigned to one of the three treatments. The cows in treatment 1 (T1 received two drenches at calving and 24h after calving. The cows in treatment 2 (T2 received three drenches at calving, 24h after calving and 7 days after calving. The cows in treatment 3 (T3 were the control. Each drench contained 143g of calcium as calcium propionate (0.68kg. Parameters studied were serum calcium, glucose and nonesterified fatty acid (NEFA concentrations, dry matter intake (DMI, BCS, milk production (MP, incidence of retained placenta (RP and metritis. Milk fever developed in 5 of 8 cows, in 3 of 8 cows and in 3 of 8 cows in T1, T2 and T3, respectively, at calving. There was no cow with milk fever in T1 and T2 at 4h after second drench (about 28h after calving but 3 of 8 cows in T3 had still milk fever at this time. The cows receiving two drenches recovered from milk fever in a shorter term as compared to the cows in T3. There were no differences among treatments for DMI, BCS, MP, RP, serum glucose and NEFA concentrations during the experimental period. There was no difference for metritis between T1 and T3 but incidence of metritis in T2 was significantly lower as compared to T3 (P<0.05. Two drenches of calcium propionate were beneficial in treating milk fever and three drenches of calcium propionate were considered to have had a preventive effect for metritis. 8. A nordic charter for universal design. Science.gov (United States) Björk, Evastina 2014-02-01 The aim of this paper is to present the result of a pioneer project; A Nordic Charter for Universal Design, which was initiated by the Norwegian Directorate for Children, Youth and Family Affairs in 2011. The purpose of the Charter was to present rationales that stated prerequisites for successful investment in Universal Design, and to establish a platform for further research and good practice. It was also meant to contribute to spreading of information and knowledge about the importance of guidance by the concept of Universal Design of initiatives with effects on the public arena. A Nordic group of researchers and professionals in the field ended up after 8 months of work with a written document: "A Nordic Charter for Universal Design", which was presented at the International Conference in Universal Design in Oslo, Norway (UD 2012). A Nordic Charter for Universal Design. Persons with disabilities often experience the public arenas environments, products and services as poorly-designed to fit their abilities and/or their needs. Together with the demographic changes in the Nordic societies with an increasing number of elderly people, it needs initiatives to improve independence, accessibility and participation in society. A strategy which aims to make design and composition of different environments, products, communication, information technology and services accessible, usable and understandable to as many as possible is Universal Design. 9. ULTRA: Universal Grammar as a Universal Parser. Science.gov (United States) Medeiros, David P 2018-01-01 A central concern of generative grammar is the relationship between hierarchy and word order, traditionally understood as two dimensions of a single syntactic representation. A related concern is directionality in the grammar. Traditional approaches posit process-neutral grammars, embodying knowledge of language, put to use with infinite facility both for production and comprehension. This has crystallized in the view of Merge as the central property of syntax, perhaps its only novel feature. A growing number of approaches explore grammars with different directionalities, often with more direct connections to performance mechanisms. This paper describes a novel model of universal grammar as a one-directional, universal parser. Mismatch between word order and interpretation order is pervasive in comprehension; in the present model, word order is language-particular and interpretation order (i.e., hierarchy) is universal. These orders are not two dimensions of a unified abstract object (e.g., precedence and dominance in a single tree); rather, both are temporal sequences, and UG is an invariant real-time procedure (based on Knuth's stack-sorting algorithm) transforming word order into hierarchical order. This shift in perspective has several desirable consequences. It collapses linearization, displacement, and composition into a single performance process. The architecture provides a novel source of brackets (labeled unambiguously and without search), which are understood not as part-whole constituency relations, but as storage and retrieval routines in parsing. It also explains why neutral word order within single syntactic cycles avoids 213-like permutations. The model identifies cycles as extended projections of lexical heads, grounding the notion of phase. This is achieved with a universal processor, dispensing with parameters. The empirical focus is word order in noun phrases. This domain provides some of the clearest evidence for 213-avoidance as a cross 10. Charged Higgs production from polarized top-quark decay in the 2HDM considering the general-mass variable-flavor-number scheme Science.gov (United States) Abbaspour, S.; Mohammad Moosavi Nejad, S. 2018-05-01 Charged Higgs bosons are predicted by some non-minimal Higgs scenarios, such as models containing Higgs triplets and two-Higgs-doublet models, so that the experimental observation of these bosons would indicate physics beyond the Standard Model. In the present work, we introduce a channel to indirect search for the charged Higgses through the hadronic decay of polarized top quarks where a top quark decays into a charged Higgs H+ and a bottom-flavored meson B via the hadronization process of the produced bottom quark, t (↑) →H+ + b (→ B + jet). To obtain the energy spectrum of produced B-mesons we present, for the first time, an analytical expression for the O (αs) corrections to the differential decay width of the process t →H+ b in presence of a massive b-quark in the General-Mass Variable-Flavor-Number (GM-VFN) scheme. We find that the most reliable predictions for the B-hadron energy spectrum are made in the GM-VFN scheme, specifically, when the Type-II 2HDM scenario is concerned. 11. Comparative evaluation of direct plating and most probable number for enumeration of low levels of Listeria monocytogenes in naturally contaminated ice cream products.

In this study, paired comparison of most probable number (MPN) and direct plating enumeration of L. monocytogenes was conducted on a total of 1730 outbreak-associated ice cream samples that were naturally contaminated with low level of L. monocytogenes. MPN was performed on all 1730 samples. Direct plating was performed on all samples using the RAPID'L.mono (RLM) agar (1600 samples) and agar Listeria Ottaviani and Agosti (ALOA; 130 samples). Probabilistic analysis with Bayesian inference model was used to compare paired direct plating and MPN estimates of L. monocytogenes in ice cream samples because assumptions implicit in ordinary least squares (OLS) linear regression analyses were not met for such a comparison. The probabilistic analysis revealed good agreement between the MPN and direct plating estimates, and this agreement showed that the MPN schemes and direct plating schemes using ALOA or RLM evaluated in the present study were suitable for enumerating low levels of L. monocytogenes in these ice cream samples. The statistical analysis further revealed that OLS linear regression analyses of direct plating and MPN data did introduce bias that incorrectly characterized systematic differences between estimates from the two methods.

Cigarette smoke induced genotoxicity and respiratory tract pathology: evidence to support reduced exposure time and animal numbers in tobacco product testing. Science.gov (United States) Dalrymple, Annette; Ordoñez, Patricia; Thorne, David; Walker, David; Camacho, Oscar M; Büttner, Ansgar; Dillon, Debbie; Meredith, Clive 2016-06-01 Many laboratories are working to develop in vitro models that will replace in vivo tests, but occasionally there remains a regulatory expectation of some in vivo testing. Historically, cigarettes have been tested in vivo for 90 days. Recently, methods to reduce and refine animal use have been explored. This study investigated the potential of reducing animal cigarette smoke (CS) exposure to 3 or 6 weeks, and the feasibility of separate lung lobes for histopathology or the Comet assay. Rats were exposed to sham air or CS (1 or 2 h) for 3 or 6 weeks. Respiratory tissues were processed for histopathological evaluation, and Alveolar type II cells (AEC II) isolated for the Comet assay. Blood was collected for Pig-a and micronucleus quantification. Histopathological analyses demonstrated exposure effects, which were generally dependent on CS dose (1 or 2 h, 5 days/week). Comet analysis identified that DNA damage increased in AEC II following 3 or 6 weeks CS exposure, and the level at 6 weeks was higher than 3 weeks. Pig-a mutation or micronucleus levels were not increased. In conclusion, this study showed that 3 weeks of CS exposure was sufficient to observe respiratory tract pathology and DNA damage in isolated AEC II. Differences between the 3 and 6 week data imply that DNA damage in the lung is cumulative. Reducing exposure time, plus analyzing separate lung lobes for DNA damage or histopathology, supports a strategy to reduce and refine animal use in tobacco product testing and is aligned to the 3Rs (replacement, reduction and refinement). 14.

The Bright Universe Cosmology International Nuclear Information System (INIS) Surdin, M. 1980-01-01 It is shown that viewed from the 'outside', our universe is a black hole. Hence the 'inside' cosmology considered is termed as the Bright Universe Cosmology. The model proposed avoids the singularities of cosmologies of the Big Bang variety, it gives a good account of the redshifts, the cosmic background radiation, the number counts; it also gives a satisfactory explanation of the 'large numbers coincidence' and of the variation in time of fundamental constants.

A lightweight universe? Science.gov (United States) Bahcall, Neta A.; Fan, Xiaohui 1998-01-01 How much matter is there in the universe? Does the universe have the critical density needed to stop its expansion, or is the universe underweight and destined to expand forever? We show that several independent measures, especially those utilizing the largest bound systems known—clusters of galaxies—all indicate that the mass-density of the universe is insufficient to halt the expansion. A promising new method, the evolution of the number density of clusters with time, provides the most powerful indication so far that the universe has a subcritical density. We show that different techniques reveal a consistent picture of a lightweight universe with only ∼20–30% of the critical density. Thus, the universe may expand forever. PMID:9600898 18.

Anthony F J van Raan

Full Text Available Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

4. Negative numbers and antimatter particles

International Nuclear Information System (INIS)

Tsan, Ung Chan

2012-01-01

Dirac's equation states that an electron implies the existence of an antielectron with the same mass (more generally same arithmetic properties) and opposite charge (more generally opposite algebraic properties). Subsequent observation of antielectron validated this concept. This statement can be extended to all matter particles; observation of antiproton, antineutron, antideuton … is in complete agreement with this view. Recently antihypertriton was observed and 38 atoms of antihydrogen were trapped. This opens the path for use in precise testing of nature's fundamental symmetries. The symmetric properties of a matter particle and its mirror antimatter particle seem to be well established. Interactions operate on matter particles and antimatter particles as well. Conservation of matter parallels addition operating on positive and negative numbers. Without antimatter particles, interactions of the Standard Model (electromagnetism, strong interaction and weak interaction) cannot have the structure of group. Antimatter particles are characterized by negative baryonic number A or/and negative leptonic number L. Materialization and annihilation obey conservation of A and L (associated to all known interactions), explaining why from pure energy (A = 0, L = 0) one can only obtain a pair of matter particle antimatter particle — electron antielectron, proton and antiproton — via materialization where the mass of a pair of particle antiparticle gives back to pure energy with annihilation. These two mechanisms cannot change the difference in the number of matter particles and antimatter particles. Thus from pure energy only a perfectly symmetric (in number) universe could be generated as proposed by Dirac but observation showed that our universe is not symmetric, it is a matter universe which is nevertheless neutral. Fall of reflection symmetries shattered the prejudice that there is no way to define in an absolute way right and left or matter and antimatter

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive women. Nearly 10% of young women in this period involved. Although factors such as Insulin Resistance, hyper insulinemia, obesity and dietary are suggested to be associated with PCOS, cause of PCOS is not completely understood. Dairy products (a key component of the usual diet) of participants can also affect the factors of this disease and may have beneficial effects on treatment of PCOS. However, research in this area is scarce. The purpose of this study was to evaluate the relationship between dairy products consumption and PCOS. This descriptive cross-sectional study of 400 women was conducted in Shahid Beheshti Hospital of Isfahan University of Medical Science, Iran. Dietary intake was evaluated by validated food frequency questionnaire. Other variables such as ovarian disease, inherited predisposition, age at menarche, physical activity and history of other diseases were evaluated using questionnaire. Data analysis was performed by a logistic regression test using SPSS software version 15 Predictive analytics software and solutions. There were a significant association between PCOS and ovarian disease (P medication (P = 0.001). Body mass index (BMI) was inversely associated with PCOS, but it was not significant (P = 0.068). There was a significant direct relationship between milk consumption and risk of PCOS after adjusting for confounding factors (P = 0.028). The findings of this study indicated that ovarian disease and medication use is directly linked to PCOS. Dairy consumption was not significantly correlated with PCOS. However, after adjustment for confounders, there was an direct relationship between milk consumption and risk of PCOS.

8. Fundamental Chemistry of the Universal Extractant (UNEX) for the Simultaneous Separation of Fission Products and Transurancies from High-Level Waste Streams

International Nuclear Information System (INIS)

Herbst, R. Scott

2004-01-01

Through collaborative research by the Idaho National Engineering and Environmental Laboratory and the Khlopin Radium Institute (St. Petersburg, Russia) the concept of a Universal Extraction (UNEX) solvent for simultaneously removing radioactive strontium, cesium, lanthanides, and transuranics from acidic aqueous waste streams in a single unit operation was developed and validated. These development efforts focused on the application of the process, where extractants were simply evaluated for extraction efficiency. The objective of this project is to conduct research that combines classical chemical techniques with advanced instrumental methods to elucidate the mechanisms of simultaneous metal extraction and study further the coordination geometries of extracted metal ions. This project is developing a fundamental understanding of the complicated, synergistic extraction chemistry of the multi-component UNEX solvent system. The results will facilitate enhancements to the process chemistry--increasing the efficiency of the UNEX process, minimizing primary and secondary waste streams, and enhancing compatibility of the product streams with the final waste forms. The global objective is implementing the UNEX process at the industrial scale

The Drell-Yan di-lepton production at hadron colliders is by far the preferred channel to search for new heavy spin-1 particles. Traditionally, such searches have exploited the Narrow Width Approximation (NWA) for the signal, thereby neglecting the effect of the interference between the additional Z{sup ′}-bosons and the Standard Model Z and γ. Recently, it has been established that both finite width and interference effects can be dealt with in experimental searches while still retaining the model independent approach ensured by the NWA. This assessment has been made for the case of popular single Z{sup ′}-boson models currently probed at the CERN Large Hadron Collider (LHC). In this paper, we test the scope of the CERN machine in relation to the above issues for some benchmark multi Z{sup ′}-boson models. In particular, we consider Non-Universal Extra Dimensional (NUED) scenarios and the 4-Dimensional Composite Higgs Model (4DCHM), both predicting a multi-Z{sup ′} peaking structure. We conclude that in a variety of cases, specifically those in which the leptonic decays modes of one or more of the heavy neutral gauge bosons are suppressed and/or significant interference effects exist between these or with the background, especially present when their decay widths are significant, traditional search approaches based on the assumption of rather narrow and isolated objects might require suitable modifications to extract the underlying dynamics.

1989-01-01

After a brief aside on charge quantization in the standard electroweak theory, I concentrate on various aspects of anomaly induced fermion number violation in the standard model. A critical analysis of the role of sphalerons for the universe's baryon asymmetry is presented and the importance of calculating directly fermion number violating Green's functions is stressed. A physical interpretation of the recent observation of Ringwald, that coherent effects in the electroweak theory lead to catastrophic fermion number violation at 100 TeV, is discussed. Possible quantum effects which might spoil this semi-classical picture are examined

Numerical results for p{sub T} -differential production cross sections are obtained at next-to-leading-order in the general-mass variable-flavor-number scheme. We compare our results with recent data from ALICE and CMS at a center-of-mass energy of 5 TeV and find good agreement. A comparison with p-p cross sections does not reveal the presence of nuclear initial-state interaction effects that could be expected to become visible as deviations of the ratio of p-Pb and p-p cross sections from one.

We discuss the phenomenology of (1,1)-mode adjoint scalars in the framework of two Universal Extra Dimensions. The Kaluza-Klein (KK) towers of these adjoint scalars arise in the 4-dimensional effective theory from the 6th component of the gauge fields after compactification. Adjoint scalars can have KK-number conserving as well as KK-number violating interactions. We calculate the KK-number violating operators involving these scalars and two Standard Model fields. Decay widths of these scalars into different channels have been estimated. We have also briefly discussed pair-production and single production of such scalars at the Large Hadron Collider

Radionuclide and metal contaminants are present in the vadose zone and groundwater throughout the U.S. Department of Energy (DOE) energy research and weapons complex. In situ containment and stabilization of these contaminants represents a cost-effective treatment strategy that minimizes workers’ exposure to hazardous substances, does not require removal or transport of contaminants, and generally does not generate a secondary waste stream. We have investigated an in situ bioremediation approach that immobilizes radionuclides or contaminant metals (e.g., strontium-90) by their microbially facilitated co-precipitation with calcium carbonate in groundwater and vadose zone systems. Calcite, a common mineral in many aquifers and vadose zones in the arid west, can incorporate divalent metals such as strontium, cadmium, lead, and cobalt into its crystal structure by the formation of a solid solution. Collaborative research undertaken by the Idaho National Laboratory (INL), University of Idaho, and University of Toronto as part of this Environmental Management Science Program project has focused on in situ microbially-catalyzed urea hydrolysis, which results in an increase in pH, carbonate alkalinity, ammonium, calcite precipitation, and co-precipitation of divalent cations. In calcite-saturated aquifers, microbially facilitated co-precipitation with calcium carbonate represents a potential long-term contaminant sequestration mechanism. Key results of the project include: **Demonstrating the linkage between urea hydrolysis and calcite precipitation in field and laboratory experiments **Observing strontium incorporation into calcite precipitate by urea hydrolyzers with higher distribution coefficient than in abiotic **Developing and applying molecular methods for characterizing microbial urease activity in groundwater including a quantitative PCR method for enumerating ureolytic bacteria **Applying the suite of developed molecular methods to assess the feasibility of the

12. Statistical effect of interactions on particle creation in expanding universe

The statistical effect of interactions which drives many-particle systems toward equilibrium is expected to change the qualitative and quantitative features of particle creation in expanding universe. To investigate this problem a simplified model called the finite-time reduction model is formulated and applied to the scalar particle creation in the radiation dominant Friedmann universe. The number density of created particles and the entropy production due to particle creation are estimated. The result for the number density is compared with that in the conventional free field theory. It is shown that the statistical effect increases the particle creation and lengthens the active creation period. As for the entropy production it is shown that it is negligible for scalar particles in the Friedmann universe. (author)

The sky uniformity can be noticed in studying the repartition of objects far enough. The sky isotropy description uses space rotations. The group theory elements will allow to give a meaning at the same time precise and general to the word a ''symmetry''. Universe models are reviewed, which must have both of the following qualities: - conformity with the physic known laws; - rigorous symmetry following one of the permitted groups. Each of the models foresees that universe evolution obeys an evolution equation. Expansion and big-bang theory are recalled. Is universe an open or closed space. Universe is also electrically neutral. That leads to a work hypothesis: the existing matter is not given data of universe but it appeared by evolution from nothing. Problem of matter and antimatter is then raised up together with its place in universe [fr

A universal word for a finite alphabet $A$ and some integer $n\\geq 1$ is a word over $A$ such that every word in $A^n$ appears exactly once as a subword (cyclically or linearly). It is well-known and easy to prove that universal words exist for any $A$ and $n$. In this work we initiate the systematic study of universal partial words. These are words that in addition to the letters from $A$ may contain an arbitrary number of occurrences of a special `joker' symbol $\\Diamond\ 15. The university with conditions Directory of Open Access Journals (Sweden) José María Ripalda Crespo 2013-03-01 Full Text Available The model of the national university is being substituted by that of the global university. At the same time, new dogmas that appear with economic labels are being imposed. All this is accompanied by important cultural changes. The Spanish university was one of the instances that was taken care of by the post-Francoist regime. Now, this regime feels strong against it, and on the other hand this university – as the whole of the productive structure – requires a reform. It is not expected that this reform will go in the direction of the university having more social presence, but rather more presence of companies. It is neither expected that it will imply more internal democracy, but more discipline. All resistance or alternative has to take into account the new situation and join the still dispersed forces that still have, however, a constitutive capacity. 16.

This operation involved the planning, training of operators of the facility, analysis of workplaces and radiometric surveys for monitoring of external radiation and surface contamination. The training involved the procedures for decontamination of surfaces, segregation of materials and practical procedures for individual monitoring of contamination outside of the body. Were also established rules for the transport of radioactive materials in the internal and external facility and release of material and sites already decontaminated 18.

The second series of experiments, conducted at constant pH and saturation state, was focused on understanding the influence of aqueous carbonate to calcium ratios on the precipitation rate of calcite. In 12 CSTR experiments (three pH levels, two ammonium carbonate levels, and two strontium levels) we found that lower pH values and ammonium carbonate concentration promoted the precipitation of calcite and the higher pH values and ammonium carbonate concentration promoted the precipitation of aragonite (as determined by X-ray diffraction). Overall, the rate of calcium carbonate precipitation increased with increasing pH and ammonium carbonate concentration, consistent with increasing values of Q/K. Intermediate conditions resulted in the precipitation of a mixture of calcite and aragonite. There was no discernible effect of strontium on the rate of precipitation or the phase precipitated. In our experiments we precipitated rhombohedral calcite, lath-shaped aragonite and inter-grown calcite-aragonite mixtures. Using Laser Ablation-Inductively Coupled Plasma-Mass Spectrometer we characterized the composition of solids from an experiment in which both calcite and aragonite precipitates were identified by X-ray diffraction. We found a range in composition from a high Sr and low Mg phase (inferred to be aragonite) to a coexisting lower Sr and higher but variable Mg phase (inferred to be calcite). Values of the distribution coefficient for strontium of 1.1 and 0.2 for aragonite and calcite, respectively were estimated from the data. These values compare to values of 1.1 and 0.1 for aragonite and calcite, respectively, determined from bulk analysis of precipitates from experiments in which only calcite or only 19. Market Positioning of Public and Private Universities:Students Perspective Directory of Open Access Journals (Sweden) Abdul-Kahar ADAM 2014-06-01 Full Text Available This paper concentrates on universities strategies for admitting students and the rate at which private sector universities expand in today’s higher educational setups. This paper answers the following question: to what extend are the public universities different from the private universities? In an attempt to find the answers, the whole study is developedtowards students’ perception of the universities positioning in terms of what they are offering to the customers, through what they prompt people to apply for admission? Therefore, thispaper looks at the prevailing admission strategies and potential students’ entry requirements at both public and private universities to determine the theoretical systems that are used by these universities in competition for customers (students. A quantitative survey of students in both public and private universities in Ghana was undergone In all, a total number of 255 questionnaires were printed. Only 187 were answered and returned out of 200 distributed questionnaires to the public sector universities whereas 55 questionnaires were distributed to the private sector students and 51 were answered and returned. This research was based on sampling data collection methods. The findings show that there are three categories of universities such as Publicly/Fully Independent Chartered Universities, Privately Owned Universities and Personal/Sole Proprietorship University Colleges. All these affect students’ choices for admission application. The findings clearly indicate that both public and private universitiespurposes are related using Pearson’s Product Moment Correlation Coefficient formulae to that of the sole proprietorship colleges. Also, the admission requirement strategies differ between public and private universities. 20.

Development of analysis method of material f low cost accounting using lean technique in food production: A case study of Universal Food Public (UFC Co.,Ltd. Directory of Open Access Journals (Sweden) Wichai Chattinnawat 2015-06-01 Full Text Available This research aims to apply Lean technique in conjunction with analysis of Material Flow Cost Accounting (MFCA to production process of canned sweet corn in order to increase process efficiency, eliminate waste and reduce cost of the production. This research develops and presents new type of MFCA analysis by incorporating value and non-value added activities into the MFCA cost allocation process. According to the simulation-based measurement of the process efficiency, integrated cost allocation based on activity types results in higher proportion of negative product cost in comparison to that computed from conventional MFCA cost allocation. Thus, considering types of activities and process efficiency have great impacts on cost structure especially for the negative product cost. The research leads to solutions to improve work procedures, eliminate waste and reduce production cost. The overall cost per unit decreases with higher proportion of positive product cost. 7.

Universal smoking installation of rotary type Directory of Open Access Journals (Sweden) Aminov V. A. 2017-11-01 Full Text Available According to the research carried out by the authors the most technological installations for producing meat and fish products are oriented only on one type of raw material (meat or fish, as well as the kind of smoking (cold or hot. Limitations are related to the maximum temperature of the drying agent that affects the product; presence of the system for maintaining the relative humidity of the air mixture; presence of the smoke cooling system coming from the smoke generator and a number of other factors. Enterprises expanding the range of products are forced to purchase new equipment. With a limited production area especially for small businesses this is not convenient. In the paper, a universal smoking installation of the rotor type (USIRT is considered for the production of both meat and fish products using cold or hot smoking. The installation is oriented to a wide range of products. The presence of the smoke cooling system will allow the production of cold smoking products, the presence of the dehumidification and humidification system for the smoke-air mixture will ensure the maintenance of the required technological regime for producing fish and meat products. Based on the example of cold smoking studies have shown that the duration of the process should be reduced while maintaining the quality of the product. For this purpose, ultrasonic (US vibrations have been applied to the smoke-air mixture in USIRT. The studies have been carried out to identify the best type of ultrasound radiators capable of transmitting vibrations of the installation metal surface and from it to pass into the smoke-air mixture in order to intensify the process of cold smoking. The necessary power of ultrasonic generators has been determined. Comparative results of technological processes with the application of ultrasound in the production of fish products have been presented. 1.

Depending on the form of the SUSY breaking potential arising from the finite energy density at early times, coherent production of scalar condensates can result along such directions. This leads a cosmological disaster for Polonyi type flat directions with only Planck suppressed couplings, but can give rise to the baryon asymmetry for standard model flat directions. Flat directions are also natural candidates to act as inflatons.

Asymptotic numbers: Pt.1 International Nuclear Information System (INIS) Todorov, T.D. 1980-01-01 The set of asymptotic numbers A as a system of generalized numbers including the system of real numbers R, as well as infinitely small (infinitesimals) and infinitely large numbers, is introduced. The detailed algebraic properties of A, which are unusual as compared with the known algebraic structures, are studied. It is proved that the set of asymptotic numbers A cannot be isomorphically embedded as a subspace in any group, ring or field, but some particular subsets of asymptotic numbers are shown to be groups, rings, and fields. The algebraic operation, additive and multiplicative forms, and the algebraic properties are constructed in an appropriate way. It is shown that the asymptotic numbers give rise to a new type of generalized functions quite analogous to the distributions of Schwartz allowing, however, the operation multiplication. A possible application of these functions to quantum theory is discussed 8. Applied number theory CERN Document Server Niederreiter, Harald 2015-01-01 This textbook effectively builds a bridge from basic number theory to recent advances in applied number theory. It presents the first unified account of the four major areas of application where number theory plays a fundamental role, namely cryptography, coding theory, quasi-Monte Carlo methods, and pseudorandom number generation, allowing the authors to delineate the manifold links and interrelations between these areas. Number theory, which Carl-Friedrich Gauss famously dubbed the queen of mathematics, has always been considered a very beautiful field of mathematics, producing lovely results and elegant proofs. While only very few real-life applications were known in the past, today number theory can be found in everyday life: in supermarket bar code scanners, in our cars’ GPS systems, in online banking, etc. Starting with a brief introductory course on number theory in Chapter 1, which makes the book more accessible for undergraduates, the authors describe the four main application areas in Chapters... 9.

Toward this end, the Department of Energy supports research projects conducted by universities and colleges to: Ensure a foundation for innovative technology through the use of the capabilities and talents in our academic institutions; provide an effective, two-way channel of communication between the Department of Energy and the academic community; and ensure that trained technical manpower is developed to carry out basic and applied research in support of DOE's mission. Fossil Energy's university activities emphasize the type of research that universities can do best - research to explore the potential of novel process concepts, develop innovative methods and materials for improving existing processes, and obtain fundamental information on the structure of coal and mechanisms of reactions of coal, shale oil, and other fossil energy sources. University programs are managed by different Fossil Energy technical groups; the individual projects are described in greater detail in this book. It is clear that a number of research areas related to the DOE Fossil Energy Program have been appropriate for university involvement, and that, with support from DOE, university scientific and technical expertise can be expected to continue to play a significant role in the advancement of fossil energy technology in the years to come. 11.

Seeking the Effects of Visual Narrative Grammar on the Written Dialogue Production of ESL Students at Japanese Universities : A Proposed Experiment OpenAIRE ファロン, トーマス J.; ベイカー, マシュー 2016-01-01 This research considers the use of Visual Narrative Grammar(VNG) as a means to aid in improving the fluency, accuracy, and complexity of dialogue written by ESL students at Japanese universities. VNG, such as the sequential images found in the panels of comic books, appeal to a non-verbal linguistic ability of the human mind (Gernsbacher, 1983; Cohn, 2013). If that be the case, then it could be hypothesized that VNG should have benefits in aiding language acquisition. This research seeks to... 13. What is the Destiny of Patents of Brazilian Universities? Directory of Open Access Journals (Sweden) André Luiz de Souza Querido 2011-03-01 Full Text Available The power of patent is expressed when the innovative product or process goes to market, and the exclusive right that patent ensures generates the market power, and the holder possibility to obtain competitive advantage over competitors. Thus, it becomes compelling the discussions on the universities need for transformation of patent applications efforts into granted patents, which could be negotiated with a higher degree of juridical certainty and, consequently, higher value added. To establish an Index of Patents Granting, and understand the importance of Technological Innovation Nuclei for the increase of this index, it was developed a survey on the number of patents granted to Brazilian universities and evaluated the structure of Technological Innovation Nuclei of these universities. From the survey on the granting cases, it was verified that the universities presenting, among other characteristics, better structured Technological Innovation Nuclei stood out. 14. 9 CFR 355.8 - Official number.

Predicting Lotto Numbers DEFF Research Database (Denmark) Jørgensen, Claus Bjørn; Suetens, Sigrid; Tyran, Jean-Robert numbers based on recent drawings. While most players pick the same set of numbers week after week without regards of numbers drawn or anything else, we find that those who do change, act on average in the way predicted by the law of small numbers as formalized in recent behavioral theory. In particular......We investigate the “law of small numbers” using a unique panel data set on lotto gambling. Because we can track individual players over time, we can measure how they react to outcomes of recent lotto drawings. We can therefore test whether they behave as if they believe they can predict lotto......, on average they move away from numbers that have recently been drawn, as suggested by the “gambler’s fallacy”, and move toward numbers that are on streak, i.e. have been drawn several weeks in a row, consistent with the “hot hand fallacy”.... 18. Invitation to number theory CERN Document Server Ore, Oystein 2017-01-01 Number theory is the branch of mathematics concerned with the counting numbers, 1, 2, 3, … and their multiples and factors. Of particular importance are odd and even numbers, squares and cubes, and prime numbers. But in spite of their simplicity, you will meet a multitude of topics in this book: magic squares, cryptarithms, finding the day of the week for a given date, constructing regular polygons, pythagorean triples, and many more. In this revised edition, John Watkins and Robin Wilson have updated the text to bring it in line with contemporary developments. They have added new material on Fermat's Last Theorem, the role of computers in number theory, and the use of number theory in cryptography, and have made numerous minor changes in the presentation and layout of the text and the exercises. 19.

The adventure of numbers CERN Document Server Godefroy, Gilles 2004-01-01 Numbers are fascinating. The fascination begins in childhood, when we first learn to count. It continues as we learn arithmetic, algebra, geometry, and so on. Eventually, we learn that numbers not only help us to measure the world, but also to understand it and, to some extent, to control it. In The Adventure of Numbers, Gilles Godefroy follows the thread of our expanding understanding of numbers to lead us through the history of mathematics. His goal is to share the joy of discovering and understanding this great adventure of the mind. The development of mathematics has been punctuated by a n 2.

While most players pick the same set of numbers week after week, we find that those who do change react on average as predicted by the law of small numbers...... as formalized in recent behavioral theory. In particular, players tend to bet less on numbers that have been drawn in the preceding week, as suggested by the ‘gambler’s fallacy’, and bet more on a number if it was frequently drawn in the recent past, consistent with the ‘hot-hand fallacy’.... 3. Beurling generalized numbers CERN Document Server Diamond, Harold G; Cheung, Man Ping 2016-01-01 "Generalized numbers" is a multiplicative structure introduced by A. Beurling to study how independent prime number theory is from the additivity of the natural numbers. The results and techniques of this theory apply to other systems having the character of prime numbers and integers; for example, it is used in the study of the prime number theorem (PNT) for ideals of algebraic number fields. Using both analytic and elementary methods, this book presents many old and new theorems, including several of the authors' results, and many examples of extremal behavior of g-number systems. Also, the authors give detailed accounts of the L^2 PNT theorem of J. P. Kahane and of the example created with H. L. Montgomery, showing that additive structure is needed for proving the Riemann hypothesis. Other interesting topics discussed are propositions "equivalent" to the PNT, the role of multiplicative convolution and Chebyshev's prime number formula for g-numbers, and how Beurling theory provides an interpretation of the ... 4. Intuitive numbers guide decisions Directory of Open Access Journals (Sweden) Ellen Peters 2008-12-01 Full Text Available Measuring reaction times to number comparisons is thought to reveal a processing stage in elementary numerical cognition linked to internal, imprecise representations of number magnitudes. These intuitive representations of the mental number line have been demonstrated across species and human development but have been little explored in decision making. This paper develops and tests hypotheses about the influence of such evolutionarily ancient, intuitive numbers on human decisions. We demonstrate that individuals with more precise mental-number-line representations are higher in numeracy (number skills consistent with previous research with children. Individuals with more precise representations (compared to those with less precise representations also were more likely to choose larger, later amounts over smaller, immediate amounts, particularly with a larger proportional difference between the two monetary outcomes. In addition, they were more likely to choose an option with a larger proportional but smaller absolute difference compared to those with less precise representations. These results are consistent with intuitive number representations underlying: a perceived differences between numbers, b the extent to which proportional differences are weighed in decisions, and, ultimately, c the valuation of decision options. Human decision processes involving numbers important to health and financial matters may be rooted in elementary, biological processes shared with other species. 5. Numbers, sequences and series CERN Document Server Hirst, Keith 1994-01-01 Number and geometry are the foundations upon which mathematics has been built over some 3000 years. This book is concerned with the logical foundations of number systems from integers to complex numbers. The author has chosen to develop the ideas by illustrating the techniques used throughout mathematics rather than using a self-contained logical treatise. The idea of proof has been emphasised, as has the illustration of concepts from a graphical, numerical and algebraic point of view. Having laid the foundations of the number system, the author has then turned to the analysis of infinite proc 6. Universality in chaos: Lyapunov spectrum and random matrix theory Science.gov (United States) Hanada, Masanori; Shimada, Hidehiko; Tezuka, Masaki 2018-02-01 We propose the existence of a new universality in classical chaotic systems when the number of degrees of freedom is large: the statistical property of the Lyapunov spectrum is described by random matrix theory. We demonstrate it by studying the finite-time Lyapunov exponents of the matrix model of a stringy black hole and the mass-deformed models. The massless limit, which has a dual string theory interpretation, is special in that the universal behavior can be seen already at t =0 , while in other cases it sets in at late time. The same pattern is demonstrated also in the product of random matrices. 7. Universality in chaos: Lyapunov spectrum and random matrix theory.

I also review the “Principle of Maximum Conformality” (PMC) which systematically sets the renormalization scale order-by-order in pQCD, eliminating an unnecessary theoretical uncertainty. The PMC allows LHC experiments to test QCD much more precisely, and the sensitivity of LHC measurements to physics beyond the Standard Model is increased. 14. University writing Directory of Open Access Journals (Sweden) Miguel Zabalza Beraza 2013-01-01 Full Text Available Writing in the University is a basic necessity and a long-range educational purpose. One of the basic characteristics of the university context is that it requires writing both as a tool of communication and as a source of intellectual stimulation. After establishing the basic features of academic writing, this article analyzes the role of writing for students (writing to learn and for teachers (write to plan, to reflect, to document what has been done. The article also discusses the contributions of writing for both students and teachers together: writing to investigate. Finally, going beyond what writing is as academic tool, we conclude with a more playful and creative position: writing for pleasure and enjoyment. 15.

Human universe CERN Document Server Cox, Brian 2014-01-01 Human life is a staggeringly strange thing. On the surface of a ball of rock falling around a nuclear fireball in the blackness of a vacuum the laws of nature conspired to create a naked ape that can look up at the stars and wonder where it came from. What is a human being? Objectively, nothing of consequence. Particles of dust in an infinite arena, present for an instant in eternity. Clumps of atoms in a universe with more galaxies than people. And yet a human being is necessary for the question itself to exist, and the presence of a question in the universe - any question - is the most wonderful thing. Questions require minds, and minds bring meaning. What is meaning? I don't know, except that the universe and every pointless speck inside it means something to me. I am astonished by the existence of a single atom, and find my civilisation to be an outrageous imprint on reality. I don't understand it. Nobody does, but it makes me smile.

Analyzing writing in english-medium instruction at university Directory of Open Access Journals (Sweden) María Sagrario Salaberri Ramiro 2015-12-01 Full Text Available The number of bilingual and English-Medium-Instruction (EMI degree programmes has grown significantly in Spanish universities during the last few years, becoming a new trend within the Bologna system. The implementation of the European Higher Education Area (EHEA led to changes in Spanish universities, promoting a shift in the teaching methods and enhancing the improvement in quality and international competitiveness pursuing an increase in mobility opportunities and the employability of the European graduates. The command of the English language in specialized university contexts became thus crucial. Research conducted at university level reveals that university students often have difficulty in performing the cognitive and discursive operations involved in the comprehension and production of written texts. These difficulties aggravate when the written performance has to be conducted in a nonnative language. The present paper analyses the written production of Chemistry students following an EMI approach at the University of Almería (Spain from a qualitative perspective. Results show the differences in the performance of certain areas of written language competence, which evidences the need to adopt methodologies that solve the problems and difficulties faced by students in order to help them integrate the global features of the writing ability within their own course contents in a second language. 1. Random number generation International Nuclear Information System (INIS) Coveyou, R.R. 1974-01-01 The subject of random number generation is currently controversial. Differing opinions on this subject seem to stem from implicit or explicit differences in philosophy; in particular, from differing ideas concerning the role of probability in the real world of physical processes, electronic computers, and Monte Carlo calculations. An attempt is made here to reconcile these views. The role of stochastic ideas in mathematical models is discussed. In illustration of these ideas, a mathematical model of the use of random number generators in Monte Carlo calculations is constructed. This model is used to set up criteria for the comparison and evaluation of random number generators. (U.S.) 2. Algebraic number theory CERN Document Server Weiss, Edwin 1998-01-01 Careful organization and clear, detailed proofs characterize this methodical, self-contained exposition of basic results of classical algebraic number theory from a relatively modem point of view. This volume presents most of the number-theoretic prerequisites for a study of either class field theory (as formulated by Artin and Tate) or the contemporary treatment of analytical questions (as found, for example, in Tate's thesis).Although concerned exclusively with algebraic number fields, this treatment features axiomatic formulations with a considerable range of applications.

Moreover, the book abounds with numerical examples and more concrete, specific theorems than are found in most contemporary treatments of the subject.The book is divided into three parts 4. The emergence of number CERN Document Server Crossley, John N 1987-01-01 This book presents detailed studies of the development of three kinds of number. In the first part the development of the natural numbers from Stone-Age times right up to the present day is examined not only from the point of view of pure history but also taking into account archaeological, anthropological and linguistic evidence. The dramatic change caused by the introduction of logical theories of number in the 19th century is also treated and this part ends with a non-technical account of the very latest developments in the area of Gödel's theorem. The second part is concerned with the deve 5.

A knowledge of such algebraic concepts as group, ring, field, and domain is not assumed, however; all terms are defined and examples are given - making the book self-contained in this respect.The author begins with an introductory chapter on number theory and its early history. Subsequent chapters deal with unique factorization and the GCD, quadratic residues, number-theoretic functions and the distribution of primes, sums of squares, quadratic equations and quadratic fields, diopha 6. Numbers and computers CERN Document Server Kneusel, Ronald T 2015-01-01 This is a book about numbers and how those numbers are represented in and operated on by computers. It is crucial that developers understand this area because the numerical operations allowed by computers, and the limitations of those operations, especially in the area of floating point math, affect virtually everything people try to do with computers. This book aims to fill this gap by exploring, in sufficient but not overwhelming detail, just what it is that computers do with numbers. Divided into two parts, the first deals with standard representations of integers and floating point numb 7. Elementary theory of numbers CERN Document Server Sierpinski, Waclaw 1988-01-01 Since the publication of the first edition of this work, considerable progress has been made in many of the questions examined. This edition has been updated and enlarged, and the bibliography has been revised.The variety of topics covered here includes divisibility, diophantine equations, prime numbers (especially Mersenne and Fermat primes), the basic arithmetic functions, congruences, the quadratic reciprocity law, expansion of real numbers into decimal fractions, decomposition of integers into sums of powers, some other problems of the additive theory of numbers and the theory of Gaussian 8. On powerful numbers Directory of Open Access Journals (Sweden) R. A. Mollin 1986-01-01 Full Text Available A powerful number is a positive integer n satisfying the property that p2 divides n whenever the prime p divides n; i.e., in the canonical prime decomposition of n, no prime appears with exponent 1. In [1], S.W. Golomb introduced and studied such numbers. In particular, he asked whether (25,27 is the only pair of consecutive odd powerful numbers. This question was settled in [2] by W.A. Sentance who gave necessary and sufficient conditions for the existence of such pairs. The first result of this paper is to provide a generalization of Sentance's result by giving necessary and sufficient conditions for the existence of pairs of powerful numbers spaced evenly apart. This result leads us naturally to consider integers which are representable as a proper difference of two powerful numbers, i.e. n=p1−p2 where p1 and p2 are powerful numbers with g.c.d. (p1,p2=1. Golomb (op.cit. conjectured that 6 is not a proper difference of two powerful numbers, and that there are infinitely many numbers which cannot be represented as a proper difference of two powerful numbers. The antithesis of this conjecture was proved by W.L. McDaniel [3] who verified that every non-zero integer is in fact a proper difference of two powerful numbers in infinitely many ways. McDaniel's proof is essentially an existence proof. The second result of this paper is a simpler proof of McDaniel's result as well as an effective algorithm (in the proof for explicitly determining infinitely many such representations. However, in both our proof and McDaniel's proof one of the powerful numbers is almost always a perfect square (namely one is always a perfect square when n≢2(mod4. We provide in §2 a proof that all even integers are representable in infinitely many ways as a proper nonsquare difference; i.e., proper difference of two powerful numbers neither of which is a perfect square. This, in conjunction with the odd case in [4], shows that every integer is representable in 9. Brief history of numbers CERN Document Server Corry, Leo 2015-01-01 The world around us is saturated with numbers. They are a fundamental pillar of our modern society, and accepted and used with hardly a second thought. But how did this state of affairs come to be? In this book, Leo Corry tells the story behind the idea of number from the early days of the Pythagoreans, up until the turn of the twentieth century. He presents an overview of how numbers were handled and conceived in classical Greek mathematics, in the mathematics of Islam, in European mathematics of the middle ages and the Renaissance, during the scientific revolution, all the way through to the 10.

Quantum field theory of the universe in the Kantowski-Sachs space-time International Nuclear Information System (INIS) Shen, Y.; Tan, Z. 1996-01-01 In this paper, the quantum field theory of the universe in the Kantowski-Sachs space-time is studied. An analogue of proceedings in quantum field theory is applied in curved space-time to the Kantowski-Sachs space-time, obtaining the wave function of the universe satisfied the Wheeler-DeWitt equation. Regarding the wave function as a universe field in the minisuperspace, the authors can not only overcome the difficulty of the probabilistic interpretation in quantum cosmology, but also come to the conclusion that there is multiple production of universes. The average number of the produced universes from nothing is calculated. The distribution of created universe is given. It is the Planckian distribution 12. University Reactor Instrumentation Program International Nuclear Information System (INIS) Vernetson, W.G. 1992-11-01 Recognizing that the University Reactor Instrumentation Program was developed in response to widespread needs in the academic community for modernization and improvement of research and training reactors at institutions such as the University of Florida, the items proposed to be supported by this grant over its two year period have been selected as those most likely to reduce foreed outages, to meet regulatory concerns that had been expressed in recent years by Nuclear Regulatory Commission inspectors or to correct other facility problems and limitations. Department of Energy Grant Number DE-FG07-90ER129969 was provided to the University of Florida Training Reactor(UFTR) facility through the US Department of Energy's University Reactor Instrumentation Program.

Each of the conferences will begin with a demonstration in the auditorium of the detection of cosmic rays and, in collaboration with Professor E. Ellberger of the Conservatoire de Musique de Genève, of how these signals from the farthest reaches of the Universe can be used to create "cosmic music". The third conference in the series, "How to build a universe?", will take place on Tuesday 15 March 2005 and the speaker will be the CERN theoretical physicist, John Ellis. A tiny number of elementary particles are responsible for the very diverse universe that surrounds us. These basic building blocks of matter interact by exchanging photons and other similar particles. After summing up what we know about these fundamental building blocks, their role in the history of the universe will be discussed. Where does matter come from? Where do the structures that ...

'Number rules the universe.' The Pythagoras 'If you wish to forsee the future of mathematics our course is to study the history and present conditions of the science.' Henri Poincaré 'The primary source (Urqell) of all mathematics are integers.' Hermann Minkowski This paper is written to commemorate the centennial anniversary of the Mathematical Association of America. It deals with a short history of different kinds of natural numbers including triangular, square, pentagonal, hexagonal and k-gonal numbers, and their simple properties and their geometrical representations. Included are Euclid's and Pythagorean's main contributions to elementary number theory with the main contents of the Euclid Elements of the 13-volume masterpiece of mathematical work. This is followed by Euler's new discovery of the additive number theory based on partitions of numbers. Special attention is given to many examples, Euler's theorems on partitions of numbers with geometrical representations of Ferrers' graphs, Young's diagrams, Lagrange's four-square theorem and the celebrated Waring problem. Included are Euler's generating functions for the partitions of numbers, Euler's pentagonal number theorem, Gauss' triangular and square number theorems and the Jacobi triple product identity. Applications of the theory of partitions of numbers to different statistics such as the Bose- Einstein, Fermi- Dirac, Gentile, and Maxwell- Boltzmann statistics are briefly discussed. Special attention is given to pedagogical information through historical approach to number theory so that students and teachers at the school, college and university levels can become familiar with the basic concepts of partitions of numbers, partition functions and their modern applications, and can pursue advanced study and research in analytical and computational number theory.

Pooser, Raphael C.

2016-05-10

A quantum random number generator (QRNG) and a photon generator for a QRNG are provided. The photon generator may be operated in a spontaneous mode below a lasing threshold to emit photons. Photons emitted from the photon generator may have at least one random characteristic, which may be monitored by the QRNG to generate a random number. In one embodiment, the photon generator may include a photon emitter and an amplifier coupled to the photon emitter. The amplifier may enable the photon generator to be used in the QRNG without introducing significant bias in the random number and may enable multiplexing of multiple random numbers. The amplifier may also desensitize the photon generator to fluctuations in power supplied thereto while operating in the spontaneous mode. In one embodiment, the photon emitter and amplifier may be a tapered diode amplifier.

In this paper, we will present a unified statistical modeling framework for estimation and forecasting sunshine number (SSN) data. Sunshine number has been proposed earlier to describe sunshine time series in qualitative terms (Theor Appl Climatol 72 (2002) 127-136) and since then, it was shown to be useful not only for theoretical purposes but also for practical considerations, e.g. those related to the development of photovoltaic energy production. Statistical modeling and prediction of SSN as a binary time series has been challenging problem, however. Our statistical model for SSN time series is based on an underlying stochastic process formulation of Markov chain type. We will show how its transition probabilities can be efficiently estimated within logistic regression framework. In fact, our logistic Markovian model can be relatively easily fitted via maximum likelihood approach. This is optimal in many respects and it also enables us to use formalized statistical inference theory to obtain not only the point estimates of transition probabilities and their functions of interest, but also related uncertainties, as well as to test of various hypotheses of practical interest, etc. It is straightforward to deal with non-homogeneous transition probabilities in this framework. Very importantly from both physical and practical points of view, logistic Markov model class allows us to test hypotheses about how SSN dependents on various external covariates (e.g. elevation angle, solar time, etc.) and about details of the dynamic model (order and functional shape of the Markov kernel, etc.). Therefore, using generalized additive model approach (GAM), we can fit and compare models of various complexity which insist on keeping physical interpretation of the statistical model and its parts. After introducing the Markovian model and general approach for identification of its parameters, we will illustrate its use and performance on high resolution SSN data from the Solar

5. Postmodernity and the university

Directory of Open Access Journals (Sweden)

Peter Scott

2012-09-01

Full Text Available The utility of post-modernism as an interpretative framework for understanding the development of contemporary higher education systems is sharply contested. Critics argue that post-modernism is, at best, a set of ideas in aesthetics, literature and critical theory with limited relevance outside these domains and, at worst, a passing intellectual fashion that is now out-of-date. However, post-modernity —or, as some would prefer, late modernity or ‘fluid’ modernity — is perhaps a more useful idea. In 21stcentury society there are a number of trends, some structural such as the growth of a knowledge-based economy and development of new patterns of knowledge production; and some conceptual such as the reconfiguration of time and space and the recognition of ‘difference’ (and risk? as key factor in the constitution of social life (and individual identity, which have a direct impact on the university. This impact is felt in two ways — first, the university is a primary engine of these transformations. Secondly, the university is shaped by these transformations (both normatively and cognitively in terms of teaching and research and structurally in terms of its organisational characteristics, governance and managementLa utilidad del postmodernismo como marco interpretativo para comprender el desarrollo de los sistemas contemporáneos de educación superior ha sido severamente contestada. Los críticos argumentan que el postmodernismo es, como mucho, un conjunto de ideas en los ámbitos de la estética, literatura y teoría crítica con relevancia limitada fuera de esos campos y, a lo peor, una moda intelectual pasajera que actualmente está caducada. No obstante, la postmodernidad —o, como algunos preferirían, la modernidad tardía o modernidad «fluida»— es quizá una idea más útil. En la sociedad del siglo XXI hay un cúmulo de tendencias, algunas estructurales, como el crecimiento de la economía basada en el conocimiento y el

Full Text Available Recognizing that developing the competences needed to appropriately use linguistic resources according to contextual characteristics (pragmatics is as important as the cultural-imbedded linguistic knowledge itself (semantics and that both are equally essential to form competent speakers of English in foreign language contexts, we feel this research relies on corpus linguistics to analyze both the scope and the limitations of the sociolinguistic knowledge and the communicative skills of English students at the university level. To such end, a linguistic corpus was assembled, compared to an existing corpus of native speakers, and analyzed in terms of the frequency, overuse, underuse, misuse, ambiguity, success, and failure of the linguistic parameters used in speech acts. The findings herein describe the linguistic configurations employed to modify levels and degrees of descriptions (salient sematic theme exhibited in the EFL learners´ corpus appealing to the sociolinguistic principles governing meaning making and language use which are constructed under the social conditions of the environments where the language is naturally spoken for sociocultural exchange.

Full Text Available The development of the Internet technology becomes the precursor of the progress of business over the Internet that is significantly growing up in the recent year. In the present, people like to shop through online shops, because in addition to its practicality, the price of goods offered is relatively affordable, and, or relatively equal to conventional stores. One of the online stores which are popular among Indonesian society, and also popular for the university student in Indonesia is Buka Lapak.com. This research aims to examine the influence of consumer behavior on their buying decisions (studies on consumer of Buka Lapak.com among the student of Universitas Negeri Jakarta . The method used in this research is quantitative method with simple linear regression analysis. The results show that student’s consumer behavior in today’s technology significantly influences the student’s buying decisions on Buka Lapak.com. This is shown by the correlation coefficient test result, in which the level of relationship between the student’s consumers behavior toward buying decisions on Buka Lapak.com is included in the category of strong and direct.

12. [University-external sector linkage: a managerial strategy].

Science.gov (United States)

Campos, Gilberto

2004-06-01

The University-External Sector vinculation is an increasing phenomenon in Latin America as in the rest of the world. The universities through its investigation processes actively participate in the creation and incorporation of science and technology to produce technological processes, to bring foreign technology into national reality, and also to create and transmit innovation for the productive sector. In those ways these institutions achieve bonds with the external sector which provide them with additional income and allows them to have certain relief for their tight teaching and investigation budgets. Several studies in university organizations have been made to identify the motivations and barriers for de adequate development of the interaction between the university and the external sector. The lack of vinculation between these institutions could be due in part to the lack of knowledge that the external sector has of the possibility to obtain services from the university, and also the lack of knowledge that the university has about the needs of potential users of their services. The goals achieved by public Venezuelan universities, in the last years, in their search of a vinculation with the external sector could grow and consolidate through an adequate strategic management plan that allows a mayor diffusion and promotion of the results of their investigations and services, to reach in a wider and more direct way, and to a greater number of potential clients.

14. Scalar transport across the turbulent/non-turbulent interface in jets: Schmidt number effects

Science.gov (United States)

Silva, Tiago S.; B. da Silva, Carlos; Idmec Team

2016-11-01

The dynamics of a passive scalar field near a turbulent/non-turbulent interface (TNTI) is analysed through direct numerical simulations (DNS) of turbulent planar jets, with Reynolds numbers ranging from 142 <= Reλ <= 246 , and Schmidt numbers from 0 . 07 <= Sc <= 7 . The steepness of the scalar gradient, as observed from conditional profiles near the TNTI, increases with the Schmidt number. Conditional scalar gradient budgets show that for low and moderate Schmidt numbers a diffusive superlayer emerges at the TNTI, where the scalar gradient diffusion dominates, while the production is negligible. For low Schmidt numbers the growth of the turbulent front is commanded by the molecular diffusion, whereas the scalar gradient convection is negligible. The authors acknowledge the Laboratory for Advanced Computing at University of Coimbra for providing HPC, computing, consulting resources that have contributed to the research results reported within this paper.
