  13. A baseline understanding of state laws governing e-cigarettes.

    2014-07-01

    Electronic cigarettes (e-cigarettes) have been available for purchase in the USA since 2007, and have grown rapidly in popularity. Currently, there are no federal restrictions on e-cigarettes; therefore, any regulations are under the purview of state and/or local governments. This study examines state laws governing e-cigarettes through youth access restrictions, smoke-free air requirements and/or excise taxation. Codified statutory and administrative laws, attorney general opinions, executive orders, and revenue notices and rulings effective as of 15 November 2013 for all 50 states and the District of Columbia, were compiled using Boolean searches in Lexis-Nexis and Westlaw. All laws were analysed by two study authors to determine the presence and components of relevant provisions. Two categories of laws were identified; (1) explicit e-cigarette laws and (2) laws focused on tobacco-derived and/or nicotine-containing products. Thirty-four states' laws address e-cigarettes either explicitly or as part of language applying to tobacco-derived or nicotine-containing products. Laws explicitly addressing e-cigarettes primarily focus on youth access (22 states) or smoke-free air (12 states); only Minnesota imposes an excise tax on e-cigarettes. Similarly, tobacco-derived or nicotine-containing products are primarily regulated through youth access restrictions (6 states), smoke-free air laws (5 states), or excise taxation (2 states). In the current absence of federal law governing e-cigarettes, more than one-half of the states have taken the initiative to regulate these products. The opportunity exists for the remaining states to incorporate e-cigarette-related restrictions into their pre-existing tobacco control laws. Published by the BMJ Publishing Group Limited.

    1994-06-01

    As part of the Hanford Federal Facility Agreement and Consent Order negotiations, the US Department and Energy, Richland Operations Office, the US Environmental Protection Agency, and the Washington State Department of Ecology agreed that liquid effluent discharges to the ground on the Hanford Site which affect groundwater or have the potential to affect groundwater would be subject to permitting under the structure of Chapter 173-216 (or 173-218 where applicable) of the Washington Administrative Code, the State Waste Discharge Permit Program. This document constitutes the State Waste Discharge Permit application for the 200-E Powerhouse Ash Pit. The 200-E Powerhouse Ash Waste Water discharges to the 200-E Powerhouse Ash Pit via dedicated pipelines. The 200-E Ash Waste Water is the only discharge to the 200-E Powerhouse Ash Pit. The 200-E Powerhouse is a steam generation facility consisting of a coal-handling and preparation section and boilers.

  16. MODELING THE DEMAND FOR E85 IN THE UNITED STATES

    How demand for E85 might evolve in the future in response to changing economics and policies is an important subject to include in the National Energy Modeling System (NEMS). This report summarizes a study to develop an E85 choice model for NEMS. Using the most recent data from the states of Minnesota, North Dakota, and Iowa, this study estimates a logit model that represents E85 choice as a function of prices of E10 and E85, as well as fuel availability of E85 relative to gasoline. Using more recent data than previous studies allows a better estimation of non-fleet demand and indicates that the price elasticity of E85 choice appears to be higher than previously estimated. Based on the results of the econometric analysis, a model for projecting E85 demand at the regional level is specified. In testing, the model produced plausible predictions of US E85 demand to 2040.

The Consent Order No. DE 91NM-177 requires a series of permitting activities for liquid effluent discharges. This document presents the State Waste Discharge Permit (SWDP) application for the 200-E Chemical Drain Field. Waste water from the 272-E Building enters the process sewer line directly through a floor drain, while waste water from the 2703-E Building is collected in two floor drains, (north and south) that act as sumps and are discharged periodically. The 272-E and 2703-E Buildings constitute the only discharges to the process sewer line and the 200-E Chemical Drain Field

    In this thesis results are presented, which are based on data, which were taken up with the detector of the ALEPH collaboration at the e + e - storage ring LEP in Geneva in the years 1990 and 1991. At c.m. energies between 88.25 GeV and 94.25 GeV the three reactions e + e - →μ + μ - μ + μ - , e + e - → e + e - μ + μ - and e + e - → e + e - e + e - were studied. After subtraction of the background from the ALEPH date the following N exp / μ +μ - μ + μ - = 4.88 ± (2.24) stat N exp / e + e - μ + μ - 24.1 (5.1) stat ± (0.16) sys and N exp / e + e - e + e - = 10.4 ± (4.1 stat) ± (0.44) sys results, while the event numbers expected according to the standard model are given by N theo / μ + μ - μ + μ - = 3.46 (0.04) stat ± (0.42) sys N theo / e + e - μ + μ - = 14.48 ± (0.19) stat ± (1.97) sys and N theo / e + e - e + e - = 12.24 ± (0.21) stat ± (1.46) sys. An X 2 test shows a confidence level of 30% for the hypothesis of the description of the data by the standard model of the electroweak interactions. Furthermore the invariant masses of the lepton pairs of the three final states studied were analyzed and a test of the universality of the photoproduction of electron and muon pairs was performed. The each measured data are in accordance with the predictions of the standard model. (orig./HSI) [de

  1. Probing color separate states in e+e- annihilation at the Z0 pole

    Hadronic events in e + e - →Z 0 are generated by a Monte Carlo model, including the production of color separate states. These events are compared with those produced by the JETSET with a default set of parameters where the color connections are color singlet chains. By selecting two jet-like events and a sensitive observable, we find that these two kinds of color connections lead to significant differences in the hadronic states

    We use the method of the color effective Hamiltonian to study the structure of color singlet chain states in N c =3 and in the large N c limit. In order to obtain their total fraction when N c is finite, we illustrate how to orthogonalize these nonorthogonal states. We give numerical results for the fraction of orthogonalized states in e + e - ->q bar qgg. With the help of a diagram technique, we derive their fraction up to O(1/N c 2 ) for the general multigluon process. For large N c the singlet chain states correspond to well-defined color topologies. Therefore we may expect that the fraction of non-color-singlet-chain states is an estimate of the fraction of events where color reconnection is possible. In the case of soft gluon bremsstrahlung, we give an explicit form for the color effective Hamiltonian which leads to the dipole cascade formulation for parton showering in leading order in N c . The next-to-leading order corrections are also given for e + e - ->qbar qg 1 g 2 and e + e - ->qbar qg 1 g 2 g 3

  3. On the relevance of the final ionic state to the (e,2e) TDCS

    Stefani, G.

    1990-01-01

    The He II n=2 satellite in the He ionisation spectrum is investigated by measuring the angular dependence of the (e, 2e) triple differential cross section (TDCS) in asymmetric geometry for the first time, at moderate momentum transfer (0.8 a 0 -1 ) and low ejected electron energy (20 eV). The generalised oscillator strengths for the transitions to the n=1 and n=2 He II states are derived from the TDCS and their ratio is in fair agreement with a recent close coupling calculation. The experimental angular distribution of the n=2 TDCS shows peculiarities, typical of continuum final-state correlations, which appear to be much more relevant when the final ionic state is the excited one.

    The scaling property of factorial moments in the multiparticle final-states of e + e - collisions is studied in both the laboratory and the thrust-axis coordinate systems by using the Jetset generator. It turns out that in both of the two cases, the 3-dimensional lnF 2 -lnM are approximately straight lines when the phase space are divided isotropically in different directions, showing that the dynamical fluctuations in the multiparticle final-state of e + e - collisions are approximately isotropic. In the lab system, the three γ parameters obtained by fitting F 2 -M of p x , p y , p z to Ochs formula respectively are approximately equal. In the thrust system, the three γ values obtained by fitting F 2 (y)-M, F 2 (p t )-M and F 2 (φ)-M are also close to each other provided the starting point in fitting F 2 (φ)-M is chosen appropriately. All of these provide further evidence for the above assertion. The results show that the essential feature, i.e. anisotropy of approximate) isotropy, of the dynamical fluctuations in soft and hard processes can be revealed by studying the scaling property of factorial moments in the collisions. Therefore, further investigation of the scaling properties of factorial moments in various kinds of collisions processes is significant for the understanding of the essential characteristics of collision dynamics

  5. Final-state interactions and relativistic effects in the quasielastic (e,e') reaction

    The longitudinal and transverse response functions for the inclusive quasielastic (e,e') reaction are analyzed in detail. A microscopic theoretical framework for the many-body reaction provides a clear conceptual (nonrelativistic) basis for treating final-state interactions and goes far beyond simple plane-wave or Hermitean potential models. The many-body physics of inelastic final-state channels as described by optical and multiple scattering theories is properly included by incorporating a full complex optical potential. Explicit nonrelativistic and relativistic momentum-space calculations quantitatively demonstrate the importance of such a treatment of final-state interactions for both the transverse and longitudinal response. Nonrelativistic calculations are performed using final-state interactions based on phenomenology, local density models, and microscopic multiple scattering theory. Relativistic calculations span a similar range of models and employ Dirac bound-state wave functions. The theoretical extension to relativistic dynamics is of course not clear, but is done in obvious parallel to elastic proton scattering. Extensive calculations are performed for 40 Ca at momentum transfers of 410, 550, and 700 MeV/c. A number of interesting physical effects are observed, including significant relativistic suppressions (especially for R L ), large off-shell and virtual pair effects, enhancement of the tails of the response by the final-state interactions, and large qualitative and even shape distinctions between the predictions of the various models of the final-state interactions. None of the models is found to be able to simultaneously predict the data for both response functions. This strongly suggests that additional physical mechanisms are of qualitative importance in inclusive quasielastic electron scattering

    A search for the Higgsstrahlung process e+e- -> hZ is described, where the neutral Higgs boson h is assumed to decay into hadronic final states. In order to be sensitive to a broad range of models, the search is performed independent of the flavour content of the Higgs boson decay. The analysis is based on e+e- collision data collected by the OPAL detector at energies between 192 GeV and 209 GeV. The search does not reveal any significant excess over the Standard Model background prediction. Results are combined with previous searches at energies around 91 GeV and at 189 GeV. A limit is set on the product of the cross-section and the hadronic branching ration of the Higgs boson, as a function of the Higgs boson mass. Assuming the hZ coupling predicted by the Standard Model, and a Higgs boson decaying only into hadronic final states, a lower bound of 104 GeV/c2 is set on the mass at the 95% confidence level.

    The inclusive production of πsup(+-) and Ksup(+-) mesons and of protons and antiprotons in e + e - annihilation has been measured at c.m. energies of W = 14, 22 and 34 GeV. Using time of flight measurements and Cerenkov counters the full momentum range has been covered. Differential cross sections and total particle yields are given. At particle momenta of 0.4 GeV/c more than 90% of the charged hadrons are pions. With increasing momentum the fraction of pions among the charged hadrons decreases. At W = 34 GeV and a momentum of 5 GeV/c the particle fractions are approximately πsup(+-) : Ksup(+-) : p,anti p = 0.55 : 0.3 : 0.15. On average an event at W = 34 GeV contains 10.3 +- 0.4 πsup(+-), 2.0 +- 0.2 Ksup(+-) and 0.8 +- 0.1 p,anti p. In addition, we present results on baryon correlations using a sample of events where two or more protons and/or antiprotons are observed in the final state. (orig.)

    Full Text Available Este artigo argumenta que no Brasil a luta de classes não alcançou dimensões profundas que pudesse engendrar a constituição do welfare state. Ao contrário, o Estado, sobretudo sua forma mais moderna, capitalista, que emergiu a partir da década de 1930, sempre se antecipou aos movimentos sociais que representassem ameaças de rupturas. De forma repressiva, o Estado brasileiro desde o Império dissipou os conflitos com o objetivo de manter uma certa harmonia em favor do processo de expansão e reprodução capitalista e a integração dos espaços regionais. O artigo, portanto, é uma tentativa, prematura, de entender o processo de constituição dos sistemas de seguridade social, analisando as experiências de alguns países e suas respectivas características, com isso confrontando alguns estudos e realizando comparações com a dinâmica da luta de classes no Brasil e a função do Estado nesse processo.This article defends the theory that the class struggle in Brazil has not been able to engender the formation of a welfare state. On the contrary, the nation which emerged in the 1930s - above all in its more modern capitalistic form - has always prevented social movements that could pose any threat of a rupture. Since when it was a monarchy, Brazil has dealt with its conflicts in a repressive fashion, with the goal of maintaining a certain harmony in the interest of the expansion and the propagation of capitalism as well as regional integration. This text, therefore, is an attempt, albeit premature, to understand the process involving the formation of the social security system in Brazil, by analyzing the experiences of a number of countries and their respective characteristics, thus examining a few studies and making comparisons with the class struggle dynamic in Brazil and the role of the State in this process.

    We have calculated the four-jet production processes e/sup +/e/sup -/ ..-->.. q anti q gg and e/sup -/e/sup -/ ..-->.. q anti q q anti q to lowest order QCD perturbation theory. We find that (q anti q q anti q) production is small compared to the dominant process e/sup +/e/sup -/ ..-->.. q anti q gg which can in part be traced to the fact that the latter process is more singular as the 2- and 3-jet phase-space limits are approached. We present differential 4-jet acoplanarity distributions and compare them with non-perturbative acoplanarity distributions at maximum PETRA and PEP energies. Leading log cross-section formulae are derived for various cut-off procedures and are compared to the results of our numerical integrations. We also present results on associated heavy quark production in e/sup +/e/sup -/ annihilation.

    We report results of an experiment to search for a resonance enhancement of the e + e- scattering cross section in a metallic Li target utilizing an energy-tunable monoenergetic positron beam. Within statistical uncertainties (0.27%) no evidence has been observed for deviations from Bhabha scattering over the entire invariant-mass region 1560 keV/c 2 X 0 2 that can be associated with the e + e- sum-peak energies in GSI heavy-ion experiments. Under the assumptions that the e + e- channel dominates, we deduce lower limits on lifetimes τ>3.3x10 -13 sec (J=0) and τ>8.2x10 -13 sec (J=1), at 90% C.L

    We study the process e+e- -> pi+pi-pi+pi-gamma, with a photon emitted from the initial-state electron or positron, using 454.3 fb^-1 of data collected with the BABAR detector at SLAC, corresponding to approximately 260,000 signal events. We use these data to extract the non-radiative sigma(e+e- ->pi+pi-pi+pi-) cross section in the energy range from 0.6 to 4.5 Gev. The total uncertainty of the cross section measurement in the peak region is less than 3%, higher in precision than the corresponding results obtained from energy scan data.

We argue that the peculiar resonance-like structures of R(e/sup +/e/sup -/ ..-->.. hadrons) for ..sqrt..s = 6 to 7 GeV may be due to production of the P-wave (cc)-(anti canti c) states.

    We extend our original study on the production of C=+ charmonium states X={eta}{sub c}(1S/2S) and {chi} {sub cJ} (1P/2P) in e{sup +}e{sup -}{yields}{gamma}+X at B factories to the BEPCII/BESIII energy region with {radical}(s)=4.0-5.0 GeV. In the framework of nonrelativistic QCD factorization, the cross sections are estimated to be as large as 0.1-0.9 pb. The results could be used to search for the missing 2P charmonium states or to estimate the continuum backgrounds in the resonance region.

  4. Ground-state correlations in 12C and the mechanism of the (e,e'p) reaction

    International Nuclear Information System (INIS)

    Steenhoven, G. van der.

    1987-01-01

    In this thesis the results of an investigation into two aspects of the mechanism of the quasi-elastic (e,e'p) reaction: the interaction between the incident electron and the bound proton and the residual nucleus (final-state interaction (FSI)), are presented and used in the extraction of nuclear-structure information from (e,e'p) measurements on 12 C. The experiments were carried out at NIKHEF-K with a high-resolution spectrometer. Two kinds of experiments have been performed on 12 C. The first was aimed at obtaining accurate momentum distributions for various final states in 11 B. Some special measurements were carried out in order to vary the parameters influencing the FSI. The role of coupled-channels effects in the 12 C(e,e'p) 11 Be reaction is discussed. It is discussed whether some of the weak transitions observed in this reaction, can be associated with knockout from normally unoccupied shell-model orbitals. The second experiment on 12 C was devoted to the e-p coupling. These measurements were supplemented with data taken on 6 Li. The latter measurement allowed for measuring simultaneously knockout from the relatively dense 4 He core and the relatively dilute deuteron. In this way the density dependence of the e-p coupling in the nucleus could be studied. The results of these experiments have been compared to various models that take into account the effect of the nuclear medium upon the e-p coupling. The possible role of charge-exchange and meson-exchange currents in the interpretation of these experiments is also considered. A brief survey of the formalism of the quasi-elastic (e,e'p) reaction is also presented. (author). 196 refs.; 53 figs.; 21 tabs

  5. Hawaii state legislator views on e-cigarettes and likelihood of legislative action.

    To examine perspectives on e-cigarette use and regulations in Hawaii through key informant interviews with state legislators. E-cigarette use is rapidly increasing, with sales in 2013 topping $1 billion in the United States, but e-cigarettes are still a largely unregulated industry. Although e-cigarettes are thought by most to be a healthier alternative to traditional cigarettes, long-term health effects are not yet known. Semistructured key informant interviews were conducted with Hawaii state legislators (n = 15). We found a lack of consensus among legislators, which suggests that substantial legislative action is unlikely in the upcoming session. However, most legislators believe that some type of incremental legislation will pass, such as enactment of a small tax, limitations on advertising to protect adolescents, or regulations concerning where people can use e-cigarettes. Legislators eagerly await further research to clarify the overall benefits and harms of e-cigarettes at both the individual and population levels.

  6. On the inclusive reaction e+e- → VX with regard for polarization states of generated vector meson

    1977-01-01

    The e + e - →VX inclusive process has been considered with allowance made for polarization states of a vector meson. The tensor that describes the vortex of the γ→VX transition has also been considered. In the general case the tensor contains eight structural functions. The elements of the vector meson density matrix have been calculated in the spiral representation. These elements are expressed in terms of the given structural functions and polarization vectors of annihilating particles. It is shown that the structural functions can be determined from the study of angular distribution of products of the meson vector decay on pseudoscalar particles (p→2π, ω→3π, phi→2K) and on a lepton-antilepton pair (PSI, PSI'→e + e - )

  9. Doubly excited circular Ba(6pj, 21c) states: e-e interaction effects in weak external fields

    International Nuclear Information System (INIS)

    Chen, L.; Cheret, M.; Poirier, M.; Roussel, F.; Bolzinger, T.; Spiess, G.

    1992-01-01

    The behaviour of doubly excited circular atoms in weak parallel electric and magnetic fields has been studied. The Hamiltonian, including the e-e interaction between the two excited electrons, Stark and Zeeman effects, is diagonalized in a truncated basis. The Rydberg electron, initially in a circular state, experiences a mixing of its orbital and magnetic quantum numbers, due to the presence of the external fields and to the excitation of the inner electron. This mixing depends on the spatial symmetry of the excited core and on the amplitude of the electric field. It can be detected by the field-ionization method which provides a new way for studying non-autoionizing doubly excited states. (orig.)

    Taking 16 O as an example of realistic nuclei, we demonstrate that a correlated ground state can be obtained as a long time solution of a time-dependent density-matrix formalism (TDDM) when the residual interaction is adiabatically treated. We also study in TDDM the E2 giant resonance of 16 O built on the correlated ground state and compare it with that built on the Hartree-Fock ground state. It is found that a spurious mixing of low frequency components seen in the latter is eliminated by using the correlated ground state. (author)

  12. State and local taxes minor factors for E and P locations

    In the main oil and gas producing states of the U.S., contrary to common perception, differences are small in the state and local tax bills on exploration and production (E and P) operations. Therefore it is unlikely that competition for exploration and investment, such as between Louisiana and Texas, depends on these taxes. It is likey that price and geological considerations dominate the selection of E and P locations. The common perception that some states could be at a disadvantage is based on two factors: First, there is a considerable variation among states in severance tax rates levied on oil and gas ranging from California's negligible rate of 2 1/2 cents/bbl to Alaska's 15% of the value of a barrel at the well. Second, state and local tax structures differ in the degree to which they rely on business taxes relative to consumer taxes. The objective of this article is to test this hypothesis by estimating the tax bill of the production industry in the leading oil and gas producing states in the U.S. The tax bills of the states are compared. This figure depicts, expressed as the per barrel of oil or gas equivalent produced in each state, the total amount paid in sales, property, corporate income or franchise, and severance taxes

In Latvia this volume is the highest, while in Estonia and Lithuania it is half as high. One of the factors that determine the RES-E production volumes is support policies, which in the Baltic States are different. The main objective of this work was to analyze and compare these support policies. The results have shown that for rapid RES-E development the most effective policy is to be market-oriented (as in Estonia, whereas for more stable development such policy should be producer-oriented (as in Lithuania.

    We present a model of cosmic ray (CR) injection into the Galactic space based on recent γ-ray observations of supernova remnants (SNRs) and pulsar wind nebulae (PWNe) by the Fermi Large Area Telescope (Fermi) and imaging atmospheric Cherenkov telescopes (IACTs). Steady-state injection of nuclear particles and electrons (e - ) from the Galactic ensemble of SNRs, and electrons and positrons (e + ) from the Galactic ensemble of PWNe are assumed, with their injection spectra inferred under guidance of γ-ray observations and recent development of evolution and emission models. The ensembles of SNRs and PWNe are assumed to share the same spatial distributions. Assessment of possible secondary CR contribution from dense molecular clouds interacting with SNRs is also given. CR propagation in the interstellar space is handled by GALPROP. Different underlying source distribution models and Galaxy halo sizes are employed to estimate the systematic uncertainty of the model. We show that this observation-based model reproduces the positron fraction e + /(e - + e + ) and antiproton-to-proton ratio ((bar p)/p) reported by PAMELA and other previous missions reasonably well, without calling for any speculative sources. A discrepancy remains, however, between the total e - + e + spectrum measured by Fermi and our model below ∼ 20 GeV, for which the potential causes are discussed. Important quantities for Galactic CRs including their energy injection, average lifetime in the Galaxy, and mean gas density along their typical propagation path are also estimated.

    Electronic waste (e-waste) generation is increasing worldwide, and its management becomes a significant challenge because of the many toxicants present in electronic devices. The U.S. is a major producer of e-waste, although its management practice and policy regulation are not sufficient to meet the challenge. We reviewed e-waste generation, current management practices and trends, policy challenges, potential health impact, and toxicant exposure prevention in the U.S. A large amount of toxic metals, flame retardants, and other persistent organic pollutants exist in e-waste or can be released from the disposal of e-waste (e.g., landfill, incineration, recycling). Landfill is still a major method used to dispose of obsolete electronic devices, and only about half of the states have initiated a landfill ban for e-waste. Recycling of e-waste is an increasing trend in the past few years. There is potential, however, for workers to be exposed to a mixture of toxicants in e-waste and these exposures should be curtailed. Perspectives and recommendations are provided regarding managing e-waste in the U.S. to protect public health, including enacting federal legislation, discontinuing landfill disposal, protecting workers in recycling facilities from toxicant exposure, reducing toxicant release into the environment, and raising awareness of this growing environmental health issue among the public.

    This study aims to evaluate the environmental impacts and benefits of state-of-the-art technologies for proper e-waste handling using Jordan as a case study. Life Cycle Assessment (LCA) was employed to evaluate five advanced management systems represent state-of-the-art treatment technologies, including sanitary landfilling; proper recycling of metals, materials, and precious metals (PMs); and incineration of plastic and the hazardous portion of printed circuit boards (PCBs). Six e-waste products that contribute the most to the e-waste in Jordan were included in the assessment of each scenario, which resulted in 30 total cases of e-waste management. The findings indicated that landfills for the entire components of the e-waste stream are the worst option and should be avoided. The most promising e-waste management scenario features integrated e-waste processes based on the concept of Integrated Waste Management (IWM), including recycling materials such as non-PMs and PMs, incinerating plastic and the hazardous content of PCBs using the energy recovered from incineration, and using sanitary landfills of residues. For this scenario, the best environmental performance was obtained for the treatment of mobile phones. Incineration of the portion of hazardous waste using energy recovery is an option that deserves attention. Because scenario implementation depends on more than just the environmental benefits (e.g., economic cost and technical aspects), the study proposes a systematic approach founded on the IWM concept for e-waste management scenario selection.

    There are many similarities in the epidemiology and transmission of hepatitis A virus (HAV) and hepatitis E virus (HEV) genotype (gt)3 infections in the United States. Both viruses are enterically transmitted, although specific routes of transmission are more clearly established for HAV than for HEV: HAV is restricted to humans and primarily spread through the fecal-oral route, while HEV is zoonotic with poorly understood modes of transmission in the United States. New cases of HAV infection have decreased dramatically in the United States since infant vaccination was recommended in 1996. In recent years, however, outbreaks have occurred among an increasingly susceptible adult population. Although HEV is the most common cause of acute viral hepatitis in developing countries, it is rarely diagnosed in the United States.

  5. On the topological ground state of E-infinity spacetime and the super string connection

    2007-01-01

    There are at present a huge number of valid super string ground states, making the one corresponding to our own universe extremely hard to determine. Therefore it may come as quite a surprise that it is a rather simple undertaking to determine the exact topological ground state of E-infinity Cantorian spacetime theory. Similar to the ground state of the Higgs for E-infinity, the expectation value of the topological ground state is non-zero and negative. Its value is given exactly by -bar o -∼ n(1/φ) n =-(4+φ 3 ) where φ=(5-1)/2 and n represents an integer Menger-Uhryson dimension running from n=0 to n=-∼. Recalling that the average dimension of ε (∼) is given by ∼ =4+φ 3 , one could interpret this result as saying that our E-infinity spacetime may be viewed as an in itself closed manifold given by the remarkable equation: + =zeroThus in a manner of speaking, the universe could have spontaneously tunnelled into existence from virtual nothingness

    To report on adults' recall of discussion by physicians and dentists about e-cigarettes. A nationally representative cross-sectional survey (Internet and random digit dialing) in the United States. Adults who ever used e-cigarettes. Participant-reported discussion about the potential benefits and harms of e-cigarettes with their doctor, dentist, or child's doctor in the past 12 months. Fisher exact test for the analysis between benefits and harms for each type of provider and for rates of advice between provider types. Among the 3030 adults who completed the survey, 523 (17.2%) had ever used e-cigarettes. Of those who had seen their doctor, dentist, or child's doctor in the last year, 7.3%, 1.7%, and 10.1%, respectively, reported discussing potential harms of e-cigarettes. Conversely, 5.8%, 1.7%, and 9.3% of patients who had seen their doctor, dentist, or child's doctor in the last year reported that the clinician discussed the potential benefits of e-cigarettes. Each clinician type was as likely to discuss harms as benefits. Rates of advice were similar between doctors and child's doctors but lower for dentists. Rates were comparable when the analysis was limited to current e-cigarette users, participants with children, or those who reported using both e-cigarettes and combusted tobacco. Few physicians and dentists discuss either the harms or benefits of e-cigarettes with their patients. These data suggest an opportunity to educate, train, and provide resources for physicians and dentists about e-cigarettes and their use.

    The lowest 13 vibrational levels, v = 0-12, of the eΠ3g state of the C2 molecule have been measured by laser-induced fluorescence of new bands of the Fox-Herzberg system. The newly observed levels, v = 5-12, which span the eΠ3g electronic state up to and beyond the first dissociation threshold of C2, were analyzed to afford highly accurate molecular constants, including band origins, and rotational and spin-orbit constants. The spin-orbit coupling constants of the previously published lowest five levels are revised in sign and magnitude, requiring an overhaul of previously published molecular constants. The analysis is supported by high level ab initio calculations. Lifetimes of all observed levels were recorded and found to be in excellent agreement with ab initio predicted values up to v = 11. v = 12 was found to exhibit a much reduced lifetime and fluorescence quantum yield, which is attributed to the onset of predissociation. This brackets the dissociation energy of ground state XΣ+1g C2 between 6.1803 and 6.2553 eV, in agreement with the Active Thermochemical Tables.

    In this paper the network structure of e-beam cured DGEBF based epoxy resins is investigated. Two epoxy systems, having different reactivity and cured in different process conditions, were analyzed through solid state NMR spectroscopy. The analysis shows that the more reactive system has higher cross-linking density and higher uniformity of network distribution. Similar information were obtained, in a previous work, on the same systems through dynamic mechanical thermal analysis. It is worth noting that unlike DMTA tests, which interfere with the molecular structure of the analyzed material, due to the heating during the analysis itself, more reliable information, without any artefact, are obtained by solid state NMR, carried out at constant room temperature. - Highlights: ► The structure of two e-beam cured epoxy systems is investigated through solid state NMR. ► The aim is to have direct information about the structure without inducing modifications. ► The different molecular structures are able to emphasize the response of solid state NMR. ► T 1 H, T 1ρ H and T CH measurements indicate different cross-linking degrees. ► The NMR results are in agreement with DMTA analysis performed in a previous paper.

    Nonsense-mediated mRNA decay (NMD) is the best-characterized mRNA surveillance mechanism; this process removes faulty mRNAs harboring premature termination codons (PTCs). NMD targets newly synthesized mRNAs bound by nuclear cap-binding proteins 80/20 (CBP80/20) and exon junction complex (EJC), the former of which is thought to recruit the ribosome to initiate the pioneer round of translation. After completion of the pioneer round of translation, CBP80/20 is replaced by the cytoplasmic cap-binding protein eIF4E, which mediates steady-state translation in the cytoplasm. Here, we show that overexpression of eIF4E-T preferentially inhibits cap-dependent steady-state translation, but not the pioneer round of translation. We also demonstrate that overexpression of eIF4E-T or Dcp1a triggers the movement of eIF4E into the processing bodies. These results suggest that the pioneer round of translation differs from steady-state translation in terms of ribosome recruitment

    Full Text Available Problem setting. In today's Ukraine reform encountered not only external but also to internal obstacles. The latter were associated not only with the lack of political will, but also with insufficient theoretical knowledge of individuals who organizes changes. Moreover, getting public office, reformers become a part of the bureaucratic state machinery and experiencing significant resistance change. This primarily occurs because of changes that the organizers do not understand the essence of bureaucracy, and therefore can not overcome its negative features. Recent research and publications analysis. In independent Ukraine the majority of works are devoted to problems of organization of public administration, mainly concentrated around corruption. However, the issue of red tape mostly ignored by the overwhelming majority state researchers. As an exception we can mention common work of V. Tsvetkova and V. Gorbatenko «Democracy – Management – Bureaucracy», in which, inter alia, considered «loss, achievements and prospects of the modernization of Ukrainian society» through the prism of theories of bureaucracy. The reform of the state mechanism have also been the subject of research, both domestic and foreign researchers. Here, in particular, we can recall the work P. Rudyk, A. Yuschyk and joint research experts and World Bank N. Manning and N. Parison and Ukrainian scientists P. Klimushkin and A. Serenok who paid a lot of attention to e-governance as a cornerstone of any factor as modern reforms. Without belittling the achievements of the above scientists should keep in mind that none of them considered reforming the state mechanism in the context of changes in the bureaucracy any other state technology, in particular e-government. Their attention is focused only on the fundamental problems of bureaucracy and e-government. Paper objective. That is why the purpose of this article is the study of e-government as anti-bureaucratic state

    The calculation of accurate differential cross sections (DCS) has always posed a litmus test for theoretical models. Among the positron-atom scattering systems, the positron-hydrogen (e{sup +}-H) atom system is the fundamental prototype. Thus, the present work utilizes 12- and 15-states coupled channel optical method (CCOM) calculations to study the DCS H(2s+2p) excitation, together with the angular correlation parameters ({lambda}(2p)), for the e{sup +}-H system at 20 eV, but up to now, there have been no measurements yet on the DCS for this system. A comparison is done with other theoretical and experimental works, including the electron case.

  13. First identification of the 02+ state in 30Mg via its E0 transition

    Schwerdtfeger, Wolfgang Norbert Erik

    2008-01-01

    The known 1789 keV level in 30 Mg turned out to be a candidate for the 0 2 + state due to its long lifetime of 3.9(4) ns and the absence of a γ transition to the ground state. This triggered our search on the 0 2 + →0 1 + E0 transition in 30 Mg following the β decay of 30 Na: β decay electrons were detected in a scintillation detector, while conversion electrons were focused onto a cooled Si(Li) detector using a Mini-Orange and detected with high resolution, which simultaneously suppresses the high background of β decay electrons. Due to the large Q value of the β decay of 30 Na (17.3 MeV) the suppression of the coincident background induced by high-energy γ rays and subsequently Compton-scattered electrons turned out to be the key challenge for the success of this experiment. In order to optimise the background suppression and thus the sensitivity to weak E0 transitions, offline test measurements using an 90 Y and a 152 Eu source were performed together with GEANT4 simulations. Resulting from these test measurements a highly sensitive experimental setup was designed and built, consequently minimising the amount of high-Z material in the target chamber, reducing X-ray production. As a by-product from test measurements the database value of the half-life of the 0 2 + state in 90 Zr could be corrected by more than 30 % to be t 1/2 =41(1) ns. Finally, in a β decay experiment at the ISOLDE facility at CERN the 0 2 + →0 1 + E0 transition in 30 Mg could be identified at the expected transition energy of 1788 keV proving for the first time shape coexistence at the borderline of the 'Island of Inversion'. This identification allows to determine the electric monopole strength as ρ 2 (E0)=26.2(7.5) x 10 -3 , indicating a rather weak mixing between the states in two potential minima in a simplified two-level mixing model. This result allows to extract the mixing amplitude between the two 0 + states as a=0.179(83). This experimental finding represents the first

From January 2012 through April 2015, the National Poison Data System received 29 141 calls for nicotine and tobacco product exposures among children younger than 6 years, averaging 729 child exposures per month. Cigarettes accounted for 60.1% of exposures, followed by other tobacco products (16.4%) and e-cigarettes (14.2%). The monthly number of exposures associated with e-cigarettes increased by 1492.9% during the study period. Children e-cigarettes had 5.2 times higher odds of a health care facility admission and 2.6 times higher odds of having a severe outcome than children exposed to cigarettes. One death occurred in association with a nicotine liquid exposure. The frequency of exposures to e-cigarettes and nicotine liquid among young children is increasing rapidly and severe outcomes are being reported. Swift government action is needed to regulate these products to help prevent child poisoning. Prevention strategies include public education; appropriate product storage and use away from children; warning labels; and modifications of e-cigarette devices, e-liquid, and e-liquid containers and packaging to make them less appealing and less accessible to children.

    We examined differential advertising strategies used by 4 major United States e-cigarette companies with differential affiliations with the traditional tobacco industry (ie, Njoy - independent, Blu - acquired, Vuse and MarkTen - launched by cigarette companies) over time. We conducted a mixed-methods study regarding e-cigarette adspend, adspend per media channel (eg, TV, print), and advertising messaging strategies among these 4 top e-cigarette brands from January 2013 through December 2015. E-cigarette adspend increased from $59 million in 2013 to $91 million in 2014, followed by a sharp decline to $37 million in 2015. These companies showed distinct spending trajectories overall and across media channels, with Njoy and Vuse spending a higher proportion of their dollars on TV and Blu and MarkTen spending more on print. Marketing messages were also different by company. Key themes included switching from cigarettes (particularly by Njoy and Blu), circumventing smoke-free policies (particularly by Blu), and technological advancement (particularly by Vuse and MarkTen). These e-cigarette brands have shifted their adspend, use of media channels, and advertising messaging strategies over time. Some differing strategies may reflect the different affiliations of each brand to the traditional cigarette industry.

    In recent era, more and more electric and electronic equipment wastes (e-wastes) are generated that contain both toxic and valuable materials in them. Most studies focus on the extraction of valuable metals like Au, Ag from e-wastes. However, the recycling of metals such as Pb, Cd, Zn, and organics has not attracted enough attentions. Vacuum metallurgy separation (VMS) processes can reduce pollution significantly using vacuum technique. It can effectively recycle heavy metals and organics from e-wastes in an environmentally friendly way, which is beneficial for both preventing the heavy metal contaminations and the sustainable development of resources. VMS can be classified into several methods, such as vacuum evaporation, vacuum carbon reduction and vacuum pyrolysis. This paper respectively reviews the state-of-art of these methods applied to recycling heavy metals and organics from several kinds of e-wastes. The method principle, equipment used, separating process, optimized operating parameters and recycling mechanism of each case are illustrated in details. The perspectives on the further development of e-wastes recycling by VMS are also presented.

  17. Serbs in political and military elites of the Ustaše's Independent State of Croatia

    Full Text Available The phenomenon of Serbian participation in the political and military elites and leadership of the Independent State of Croatia was not enough or rather not at all scientifically analysed and researched. The purpose of this paper is to inspire the historians of our recent past to research and critically evaluate the problems. In the beginning of the war during the establishment of the Independent State of Croatia, the Serbs were not involved in the Home Guard units as regular armed forces of Independent State of Croatia. Along with the development of the Independent Ustaš State of Croatia, the necessity for Serbian participation in Home Guard units arose. The Serbs were mainly educated in Austro-Hungarian schools for officers. They also participated in the armed forces of the Kingdom of Serbs, Croats and Slovenes i.e. the Kingdom of Yugoslavia. The most prominent among them were: Dr Savo Besarović, general Teodor Dragojlov, general Đuro Dragičević, general Đuro Grujić, a knight, general Milan Desović, general Mihailo Lukić, general Dušan Palčić, general Miroslav Opačić (Fridrich, a church official Zvonimir Stimaković, general Miloš Obrknežević, Minister without portfolio Ljubomir Antić, general Lalislav Milić, general Milan Uzelac and others. Apart from being the most prominent ones in the Home Guard units, there were Serbs in the political elites of the Independent State of Croatia, as well as in the Presidency of the Parliament and in the positions of the Ministers in the Independent State of Croatia. This phenomenon should be an example for future generations, in a case of war, not to happen that one part of the people takes the enemy side because the greatest sin ever is to betray its own people and country.

  18. Delitto d’onore, ordine tribale e Stato - Honour crimes, tribal order and the State

    Full Text Available Globalization does not only mean that the Western world is pervading the non-Western world but also that the non-Western world, through migration processes, moves and settles in the Western world. The impressive number of honor crimes committed every year in the Western world suggests that a different social political order is acting on the Western stage. Honor crimes are committed in Muslim communities that have their roots in those parts of the Muslim world which have tribal societies on their territories, i.e. tribal institutions and laws which interact with or ignore State law. This is a political order which is stateless and based on blood ties – the author calls it an “ematocracy” – and it is perfectly able to survive within the different shapes taken by the State – when there is the State – but also without the State when it is considered as unreliable or when, for some reasons, it collapses. The author argues that political order based on blood ties is considered as reliable by the social actors since it is permanent and in expansion: blood ties reproduce themselves as long as there is life. And women – as protagonists of reproduction processes – are unfortunately at the heart of the conflict between State laws and customary law both in their home countries and in their new homes. Through an analysis of the intertwinement between State law and customary law, in some of the home countries of the migrants, and between shariya and customary law in the classical doctrine, the author shows how this process of ordering the world carries on its political projects in the post-global context.

  19. Attenuation factors for B(E2) in the microscopic description of multiphonon states

    With an exactly solvable O(4) model of Piepenbring, Silvestre-Brac and Szymanski, we demonstrate that the attenuation factor for the B(E2) values, derived by the lowest-order approximation of the multiphonon method, takes excellent care of the kinematical anharmonicity effects, if multiphonon states are defined in the intrinsic subspace orthogonal to the pairing rotation. It is also shown that the other attenuation effect characterizing the interacting boson model is not a dominant effect in the model analysed here. (author)

    The process e^+e^- -> gamma gamma (gamma) is studied using data recorded with the OPAL detector at LEP. The data sample corresponds to a total integrated luminosity of 25.38 pb^{-1} taken at centre-of-mass energies of 130-172 GeV. The measured cross-sections agree well with the expectation from QED. In a combined fit using data from all centre-of-mass energies, the angular distribution is used to obtain improved limits on the cut-off parameters: Lambda_+ > 195 GeV and Lambda_- > 210 GeV (95% CL). In addition, limits on non-standard e^+e^-gamma couplings and contact interactions, as well as a 95% CL mass limit for an excited electron, M_{e^*} > 194 GeV for an e^+e^-gamma coupling kappa = 1, are determined.

  4. Stress state and movement potential of the Kar-e-Bas fault zone, Fars, Iran

    The Kar-e-Bas or Mengharak basement-inverted fault is comprised of six segments in the Zagros foreland folded belt of Iran. In the Fars region, this fault zone associated with the Kazerun, Sabz-Pushan and Sarvestan faults serves as a lateral transfer zone that accommodates the change in shortening direction from the western central to the eastern Zagros. This study evaluates the recent tectonic stress regime of the Kar-e-Bas fault zone based on inversion of earthquake focal mechanism data, and quantifies the fault movement potential of this zone based on the relationship between fault geometric characteristics and recent tectonic stress regimes. The trend and plunge of σ 1 and σ 3 are S25°W/04°-N31°E/05° and S65°E/04°-N60°W/10°, respectively, with a stress ratio of Φ = 0.83. These results are consistent with the collision direction of the Afro-Arabian continent and the Iranian microcontinent. The near horizontal plunge of maximum and minimum principle stresses and the value of stress ratio Φ indicate that the state of stress is nearly strike-slip dominated with little relative difference between the value of two principal stresses, σ 1 and σ 2. The obliquity of the maximum compressional stress into the fault trend reveals a typical stress partitioning of thrust and strike-slip motion in the Kar-e-Bas fault zone. Analysis of the movement potential of this fault zone shows that its northern segment has a higher potential of fault activity (0.99). The negligible difference between the fault-plane dips of the segments indicates that their strike is a controlling factor in the changes in movement potential.

    Electronic cigarettes (e-cigarettes) have been steadily increasing in popularity since their introduction to US markets in 2007. Debates surrounding the proper regulatory mechanisms needed to mitigate potential harms associated with their use have focused on youth access, their potential for nicotine addiction, and the renormalization of a smoking culture. The objective of this study was to describe the enacted and planned regulations addressing this novel public health concern in the US. We searched LexisNexis Academic under Federal Regulations and Registers, as well as State Administrative Codes and Registers. This same database was also used to find information about planned regulations in secondary sources. The search was restricted to US documents produced between January 1(st), 2004, and July 14(th), 2014. We found two planned regulations at the federal level, and 74 enacted and planned regulations in 44 states. We identified six state-based regulation types, including i) access, ii) usage, iii) marketing and advertisement, iv) packaging, v) taxation, and vi) licensure. These were further classified into 10 restriction subtypes: sales, sale to minors, use in indoor public places, use in limited venues, use by minors, licensure, marketing and advertising, packaging, and taxation. Most enacted restrictions aimed primarily to limit youth access, while few regulations enforced comprehensive restrictions on product use and availability. Current regulations targeting e-cigarettes in the US are varied in nature and scope. There is greater consensus surrounding youth protection (access by minors and/or use by minors, and/or use in limited venues), with little consensus on multi-level regulations, including comprehensive use bans in public spaces.

    Quantum chemistry packages can be used to predict with reasonable accuracy spin-rotation hyperfine interaction constants for methanol, which contains one methyl-top internal rotor. In this work we use one of these packages to calculate components of the spin-rotation interaction tensor for acetaldehyde. We then use torsion-rotation wavefunctions obtained from a fit to the acetaldehyde torsion-rotation spectrum to calculate the expected magnitude of hyperfine splittings analogous to those observed at relatively high J values in the E symmetry states of methanol. We find that theory does indeed predict doublet splittings at moderate J values in the acetaldehyde torsion-rotation spectrum, which closely resemble those seen in methanol, but that the factor of three decrease in hyperfine spin-rotation constants compared to methanol puts the largest of the acetaldehyde splittings a factor of two below presently available Lamb-dip resolution.

  7. E-Government Attempts in Small Island Developing States: The Rate of Corruption with Virtualization.

    2017-12-01

    In recent years, many Small Island Developing State (SIDS) governments have worked to increase openness and transparency of their transactions as a means to enhance efficiency and reduce corruption in their economies. In order to achieve a cost-effective and efficient strategy to implement a transparent government, Information Communication Technologies offer an opportunity of virtualization by deploying e-government services to promote transparency, accountability and consistency in the public sector and to minimize corruption. This paper explores the potential impact of government virtualization by SIDS and against corruption by comparing the corruption perception index (CPI) rates of 15 SIDS countries. The CPI relates to the degree by which corruption is perceived to exist among public officials and politicians by business people and country analysts. In order to reveal the long-term impact of virtual deployment and its consequences on corruption, an in-depth case analysis based on the CPI index rates was conducted on the deployment of the e-government system in Cyprus.

    The microstructure, phase and element compositions of oxide films of E110 (Zr-1%Nb) and E635 (Zr-1%Nb-0,35%Fe-1,2%Sn) alloys after autoclave tests in pure water had been studied by the method of transmission electron microscopy (TEM) with energy dispersive X-ray spectroscopy (EDS). TEM investigations of oxide film structure were carried on different oxide layers according to their thickness (near interface of “metal-oxide”, in central part of the oxide film and near outer surface) and in cross-section. The results of the tests show that oxide films of the alloys have different microstructure (grain size, fraction of tetragonal phase, content of defects, etc) and the phase compositions. The crystal structure of oxide films is mainly monoclinic, however, at the “metal-oxide” interface there are a significant fraction of the tetragonal phase. Researching of oxides on different stages of oxidation allow us to determine the kinetics of the second phase precipitate structure change: a) in E635 alloy at early oxidation stages of the amorphization process of the Laves phase precipitates begins with decreasing the content of iron and niobium; b) in E110 alloy the amorphization process of β-Nb precipitates begins at a later stage of oxidation. The influence of changes of the crystal structure and the chemical composition of the second phase precipitates on protective properties of the oxides had been determined. Researching of alloying element redistribution in E635 alloy oxide film shows that iron and niobium are concentrated in pores. Increased porosity of the E635 alloy oxide films at a later oxidation stage, in comparison with the E110 alloy, shows the influence of change composition and subsequent dissolution of the Laves phase particles on the pore formation in the oxide.

    The study of electronically excited van der Waals (vdW) systems presents a challenge for the theory of intermolecular interactions, and here we show how far ab initio computations can go. We found that the interaction energies for such electronically excited systems can indeed be determined, providing a reliable and accurate description for the E state potential of the HeI 2 , that in combination with the ground X and electronic excited B state of the complex, is useful to model experimental data related with potential minima and also predict higher vibrational vdW states

    Full Text Available Configurational isomerization of stereo-defined 5-substituted and unsubstituted 2-alkylidene-4-oxothiazolidines (1 in the solid state, giving the Z/E mixtures in various ratios, was investigated by 1H-NMR spectroscopy, X-ray powder crystallography and differential scanning calorimetry (DSC. The Z/E composition can be rationalized in terms of non-covalent interactions, involving intermolecular and intramolecular hydrogen bonding and directional non-bonded 1,5-type S×××O interactions. X-Ray powder crystallography, using selected crystalline (Z-4-oxothiazolidine substrates, revealed transformation to the amorphous state during the irreversible Z®E process. A correlation between previous results on the Z/E isomerization in solution and now in the solid state was established.

    The authors have previously reported the 11-state and 19-state R-matrix calculations of 1 1 S-2 3,1 S and 1 1 S-2 3 P differential cross sections at low energies. In this paper, the same R-matrix calculations are extended to obtain the differential cross sections and the electron-photon coincidence parameters λ and |Χ| for the excitation of the ground state helium to the 2 1 P state. Convergence studies are carried out between the 11-state and 19-state R-matrix calculations. Only the 19-state R-matrix results are presented in full at scattering angles of 20 o , 30 o , 60 o , 90 o , 120 o and 140 o from the excitation threshold up to 23.8 eV. (author)

    Full Text Available The aim of the article is to study the theoretical and methodological principles of the state regulation and accounting and analytical support of the development of e-commerce in the consumer sector. The peculiarities of the state regulation and accounting and analytical support of the development of e-commerce in the consumer sector have been considered. The international and domestic experience in the field of regulatory support of e-commerce is studied. There systematized the ways of solving the problems of e-commerce in Ukraine based on the need to minimize the direct regulation with the perfection of the institutional environment to improve business conditions including the issues of the fiscal regime and simplification of the customs tariff regulation. The state regulation of e-commerce should constructively contribute to the development of entrepreneurship among other measures by solving the problem of financial control of electronic transactions and supporting the payment infrastructure of e-commerce in the consumer market on the basis of its corresponding accounting and analytical support. Prospects of further research in this direction are definition of a clear and harmonized with international standards state policy in the sphere of regulation of e-commerce in the consumer market on the basis of the relevant accounting and analytical support, since the appearance of new objects and forms of economic activity sets new tasks for the accounting, which develops in parallel with these changes and generates information for managing at both the micro and macro level.

    The cross section for e+e-→π+π-J/ψ between 3.8 and 5.5GeV/c2 is measured using a 548fb-1 data sample collected on or near the Υ(4S) resonance with the Belle detector at KEKB. A peak near 4.25GeV/c2, corresponding to the so called Y(4260), is observed. In addition, there is another cluster of events at around 4.05GeV/c2. A fit using two interfering Breit-Wigner shapes describes the data better than one that uses only the Y(4260), especially for the lower-mass side of the 4.25 GeV enhancement.

    Yellow fever (YF) is a vector-borne disease transmitted to humans by infected Aedes mosquitoes, while hepatitis E virus (HEV) is a waterborne disease that is transmitted through the fecal-oral route. Both diseases have very close clinical presentation, namely fever, jaundice, malaise, and dark urine; they differ in severity and outcome. In this cross-sectional, laboratory-based study, an attempt was made to measure the correlation of concomitant YF and HEV infection in Darfur States during the previous YF outbreak in 2012. Results found concomitant outbreaks of YF and HEV at the same time with very weak statistical correlation between the two infections during the outbreak period, with Cramer's V correlation 0.05 and insignificant p value of 0.86. This correlation indicates that clinicians and care providers in tropical areas have to deal with clinical case definitions used for disease surveillance very carefully since prevalence of HEV infection is relatively common and this increases the possibility of misclassification and missing YF cases, particularly initial index cases, in a season or outbreak.

    While the islands of Sao Tome e Principe (STP) were once a leading cocoa producer, cocoa production is now relatively insignificant and the country is little known today outside the lusophone world. But STP could soon gain strategic and economic importance as its territorial waters are suspected to hold large quantities of crude oil. This article explores STP's shift away from domination by cocoa exports, narrating the decline and final collapse of the plantation economy and the country's slide towards overwhelming dependence on external assistance in the form of foreign aid and external debt. In this context, it calls STP an unviable state as its fledgling domestic economy fails to generate enough revenue to sustain its highly import-reliant consumption patterns. But it finds STP on the verge of another major transformation as it is likely to become a crude oil producer within a few years. In the course of this research, the authors came across major irregularities in the conduct of the country's oil policy and some of this information appears for the first time in the public domain. In this context, their research points to opportunities for rent-seeking and corrupt behaviour, which stem from access to foreign aid and natural resources. (author)

    In recent years, self-reported cigarette smoking has declined among youth and adults, while electronic cigarette (e-cigarette) use has increased. However, sales trends for these products are less certain. This study assessed national and state patterns of U.S. cigarette and e-cigarette unit sales. Trends in cigarette and e-cigarette unit sales were analyzed using retail scanner data from September 25, 2011 through January 9, 2016 for: (1) convenience stores; and (2) all other outlets combined, including supermarkets, mass merchandisers, drug, dollar, and club stores, and military commissaries (online, tobacco-only, and "vape" shops were not available). Data by store type were available for the total contiguous U.S. and 29 states; combined data were available for the remaining states, except Alaska, Hawaii, and DC. During 2011-2015, cigarette sales exhibited a small, significant decrease; however, positive year-over-year growth occurred in convenience stores throughout most of 2015. E-cigarette unit sales significantly increased during 2011-2015, but year-over-year growth slowed and was occasionally negative. Cigarette unit sales exceeded e-cigarettes by 64:1 during the last 4-week period. During 2014-2015, cigarette sales increases occurred in 15 of 48 assessed states; e-cigarette sales increased in 18 states. Despite overall declines during 2011-2015, cigarette sales in 2015 grew for the first time in a decade. E-cigarette sales growth was positive, but slowed over the study period in assessed stores. Cigarette sales continued to exceed e-cigarette sales, reinforcing the importance of efforts to reduce the appeal and accessibility of cigarettes and other combusted tobacco products.

  2. Shape resonances and the excitation of helium autoionising states by electrons in the 57-66 eV region

    1986-01-01

    Optical excitation functions of singly excited helium states are presented, measured by detecting the yield of emitted photons as a function of the incident electron energy from 56 to 66 eV. Many structures are observed, which are caused by negative-ion resonances and by the decay of autoionising states followed by post-collision interaction. Some of the structures are interpreted as being caused by hitherto unknown shape resonances lying very close to the thresholds of a particular class of autoionising states. As these shape resonances almost exclusively decay to their respective parent (autoionising) states, thereby considerably enhancing the threshold excitation cross sections of these states, they can only be observed via the PCI effect on the excitation functions of (higher lying) singly excited states. Using the recently introduced supermultiplet classification for doubly excited states a selection rule for the near-threshold excitation of doubly excited states by electron impact is deduced from the measurements. Only states with large probabilities in the Wannier region of configuration space (where the two electrons are at nearly equal distances and on opposite sides of the nucleus) are strongly excited. It is pointed out that these states are precisely the states that can support the above mentioned shape resonances at their thresholds. (author)

    A description is given of doubly and triply excited negative-ion states and their effects on the electron impact excitation of atomic states. Mechanisms for indirect excitation of singly excited states are discussed with respect to:- negative-ion resonance, autoionisation and post-collision interaction, and excitation of an autoionising state via a negative ion resonance. A classification of doubly excited states is considered. Experimental results on the excitation of the n'S states of helium as a function of the incident electron energy are presented, along with theoretical PCI (post collision interaction) profiles in excitation functions, and an interpretation of the results.

    IMPORTANCE The prevalence of electronic cigarette (e-cigarette) use is increasing. Population health effects will depend on cigarette smoking behaviors, levels of dual use with conventional cigarettes, and e-cigarette toxicity. OBJECTIVE To evaluate potential health effects of various scenarios of increasing promotion and use of e-cigarettes. DESIGN, SETTING, AND PARTICIPANTS A base case model was developed using data on actual cigarette and e-cigarette use patterns that quantifies transitions from an initial state of no cigarette or e-cigarette use to 1 of 5 final states: never use of cigarettes or e-cigarettes, cigarette use, e-cigarette use, dual use of cigarettes and e-cigarettes, or quit. Seven scenarios were created that cover a range of use patterns, depending on how the e-cigarette market might develop, as well as a range of possible long-term health effects of e-cigarette use. Scenarios for changes from the base case were evaluated using Monte Carlo simulations. Separate sets of base case model parameters were evaluated for the US and UK populations. MAIN OUTCOMES AND MEASURES We assigned unitless health “costs” for each final state on a scale of 0 to 100. Population health “costs” were compared with the base case (status quo) assuming e-cigarette use health “costs” from 1% to 50% as dangerous as conventional cigarette use health costs. RESULTS Compared with the base case, a harm reduction scenario in which e-cigarette use increases only among smokers who are interested in quitting with more quit attempts and no increased initiation of e-cigarette use among nonsmokers, and another scenario in which e-cigarettes are taken up only by youth who would have smoked conventional cigarettes, had population-level health benefits regardless of e-cigarette health costs in both the United States and United Kingdom. Conversely, scenarios in which e-cigarette promotion leads to renormalization of cigarette smoking or e-cigarettes are used primarily by youth

    A potential which incorporates the concepts of confinement and asymptotic freedom, previously utilized in the description of the spectroscopy of mesons and baryons, is extended to the gluon sector. The mass spectroscopy of glueballs and hybrids is analyzed considering only pairwise potentials and massive constituent gluons. The mass spectrum of the color octet two-gluon system is adopted as a suitable description of the intermediate states of hadronic transitions, within the framework of the multipole expansion for quantum chromodynamics. The spin-dependent effects in the gluonium spectrum, associated with the Coulombian potential, are calculated through the inverted first Born approximation for the gluon-gluon scattering.

    We report on the investigation of dielectron production in tagged quasi-free neutron-proton collisions by using a deuteron beam of kinetic energy 1.25 GeV/u impinging on a liquid hydrogen target. Our measurements with HADES confirm a significant excess of e"+e"- pairs above the π"0 mass in the exclusive channel dp → npe"+e"-(p_s_p_e_c_t) as compared to the exclusive channel ppe"+e"- measured in proton-proton collisions at the same energy. That excess points to different bremsstrahlung production mechanisms. Two models were evaluated for the role of the charged pion exchange between nucleons and double-Δ excitation combined with intermediate ρ-meson production. Differential cross sections as a function of the e"+e"- invariant mass and of the angles of the virtual photon, proton and electrons provide valuable constraints and encourage further investigations on both experimental and theoretical sides.

    Full Text Available In this paper we look at the literature related to partnership between state and civil society, especially partnership between public and non-for-profi t organisations. We discuss the differing perspectives of partnership and attempt to identify some of the main theoretical concerns about partnership between state and civil society in the governance context. In this paper, we argue that the historical background of partnership has not been included among factors used in explaining the resort to partnership in governance. In spite of existing analyses showing that partnership brings social benefi ts in their own right, we try to show that there is no evidence that this ‘social technology’ contributes effectively to bringing power to powerless people and social groups. Most of the literature shows that partnership tries to make relationship between local people and local governance stronger and improve the possibilities for powerless people and social groups to participate in local governance. However, we do not fi nd clear evidence in the literature that partnership allows for a shift in political power.

    In the context of different regulatory environments, different patterns of e-cigarette use have emerged among adolescents worldwide. One example is the United States and South Korea, the latter of which has maintained much more extensive regulation of e-cigarettes. This analysis compares the prevalence of e-cigarette and conventional cigarette use between 2011 and 2015 from the Korean Youth Risk Behavior Web-based Survey and the U.S. National Youth Tobacco Survey, both nationally representative samples of middle and high school students that use similar questions. E-cigarette prevalence (past 30 day) among Korean adolescents decreased from 4.7% in 2011 (95% confidence interval [CI]: 4.4-5.0) to 4.0% in 2015; (3.7-4.3) but increased dramatically among U.S. adolescents from 0.9% (0.7-1.2) to 11.2% (9.9-12.7). Cigarette prevalence (past 30 day) decreased in Korea from 12.1% (11.6-12.7) to 7.8% (CI: 7.3-8.3) and in the United States from 11.1% (9.5-12.6) to 6.1% (5.1-7.3). Combined prevalence of cigarette and e-cigarette use (adjusting for dual users) decreased in Korea from 13.2% (12.7-13.8) to 8.5% (8.0-9.1) but increased in the United States from 11.3% (9.7-12.9) to 14.0% (12.4-15.7). In Korea, where e-cigarettes are extensively regulated, adolescent e-cigarette use remained stable at a low level, whereas in the United States, where e-cigarette regulation has been limited, e-cigarette use increased. Combined e-cigarette plus cigarette use declined in Korea whereas it increased in the US. The restrictive policies in Korea likely contributed to lower overall tobacco product use. © The Author 2017.

    A solid-state source based terahertz (THz) interferometer diagnostic system has been designed and characterized for the Keda Torus eXperiment (KTX). The THz interferometer utilizes the planar diodes based frequency multiplier (X48) to provide the probing beam at fixed frequency 0.650 THz, and local oscillator is provided by an independent solid-state diode source with tunable frequency (0.650 THz +/− 10 MHz). Both solid-state sources have approximately 1 mW power. The planar-diode mixers optimized for high sensitivity, ∼750 mV/mW, are used in the heterodyne detection system, which permits multichannel interferometer on KTX with a low phase noise. A sensitivity of e l> min = 4.5 × 10 16 m −2 and a temporal resolution of 0.2 μs have been achieved during the initial bench test

    E-cigarette advertising has been shown to be associated with use of e-cigarettes, but its association with tobacco use has not been studied. Therefore, we examined the association between e-cigarettes advertisement and tobacco use. Data from nationally representative 22,007 middle and high school students (grades 6-12) were used to conduct the analysis. Logistic regression models estimated the adjusted odds ratios (AOR) of ever and current use of cigarette, hookah, cigar, and polytobacco use. Odds ratios were weighted and adjusted for study design, non-response rates, school level, gender, race/ethnicity, e-cigarette use, and smoking at home. E-cigarette marketing exposure was significantly associated with ever use of cigarettes (AOR: 1.3, 95% CI: 1.1-1.5), hookah (AOR: 1.4, 95% CI: 1.2-1.7), cigars (AOR: 1.5, 95% CI: 1.4-1.6), and polytobacco (AOR: 1.7, 95% CI: 1.5-1.8). Likewise, E-cigarette marketing exposure was significantly associated with current use of cigarettes (AOR: 1.3, 95% CI: 1.1-1.6), hookah (AOR: 1.3, 95% CI: 1.03-1.7), cigars (AOR: 1.3, 95% CI: 1.1-1.6), and polytobacco use (AOR: 1.8, 95% CI: 1.5-2.1). The results suggest that e-cigarette advertisement is associated with use of cigarettes, hookah, cigars, and polytobacco products. These results add to the evidence about the risks of e-cigarette marketing and highlight the need for stricter regulation of e-cigarette advertisements. Copyright © 2017 Elsevier Ltd.

    The experiment R704 at the CERN Intersecting Storages Rings (ISR) utilised a completely new technique for charmonium spectroscopy, using a cooled antiprotons beam in collision with protons of a dense, molecular H 2 ''jet target''. ISR operations, jet target and experimental apparatus are described. Observation of the reaction pantip#-> #J/Ψ#-> #e + e - (193 evts for an integrated luminosity of 141 nb -1 ) and estimation of the J/Ψ mass using the beam parameters (3096.95±0.1±0.27 MeV) are used to test the method, the energy calibration and the reproductibility of the ISR. From these results, a very good precision of ± 300 KeV is expected in the later results on J PC ≠ 1 -- states. In addition, we give new upper limits for the magnetic form factor of the proton at high transfer [fr

    Full Text Available Background. The effect of vitamin E on health-related conditions has been extensively researched, with varied results. However, to date, there was no published review of the effect of vitamin E on bone fracture healing. Purpose. This paper systematically audited past studies of the effect of vitamin E on bone fracture healing. Methods. Related articles were identified from Medline, CINAHL, and Scopus databases. Screenings were performed based on the criteria that the study must be an original study that investigated the independent effect of vitamin E on bone fracture healing. Data were extracted using standardised forms, followed by evaluation of quality of reporting using ARRIVE Guidelines, plus recalculation procedure for the effect size and statistical power of the results. Results. Six animal studies fulfilled the selection criteria. The study methods were heterogeneous with mediocre reporting quality and focused on the antioxidant-related mechanism of vitamin E. The metasynthesis showed α-tocopherol may have a significant effect on bone formation during the normal bone remodeling phase of secondary bone healing. Conclusion. In general, the effect of vitamin E on bone fracture healing remained inconclusive due to the small number of heterogeneous and mediocre studies included in this paper.

    E-cigarettes are relatively new products that simulate the smoking experience. This descriptive study assessed changes in e-cigarette availability and promotions among retailers in 11 college communities in North Carolina and Virginia during a 1-year period. During the spring of 2012 and 2013, observers completed assessments in 320 tobacco-selling retailers, including grocery and convenience stores, pharmacies, and tobacco shops. Assessors collected e-cigarette availability, advertising, price, and promotions. E-cigarette availability increased among retailers from 24.7% in 2012 to 59.9% in 2013. They were available in the form of disposables and reusable kits and were most frequently available in tobacco shops, convenience stores, and pharmacies. The average price for disposables was $9.70 (SD = 1.07) in 2012 and $9.61 (SD = 2.10) in 2013; the average price for kits was $39.58 (SD = 15.79) in 2012 and $32.59 (SD = 18.65) in 2013.

    2007-01-01

    The movement to e-government is basically about changing the way people and business interact with government. Kuwait, like any developing country, is currently launching major e-service projects aiming at improving government processes, connect government to citizens, and build interaction within the civil society. The e-services category of e-government applications enables interactions and relationships between the government and citizens, through which the latter gain access to a range of public services. However, the implementation process of e-services involves many factors of risk that could threaten the success of process. Therefore, an effective risk management process is an important component of a successful information security program. This paper investigates and discusses the possibilities of e-services risk areas and assesses the security and privacy protection issues in some ministries in Kuwait. The results show that the total average percentage of applying security and privacy issues in the studied ministries is moderate. The Ministry of Communication (MoC) has the highest percentage of applications, whereas the Ministry of Trading and Industry (MoTI) has the lowest. Physical security is the highest applied variable, while prevention of unauthorized access is the lowest one. (author)

  6. On the origin of high spin states (J > Jsub(max) of IBA=10) and their enhanced E1 decay mode in 218Ra

    International Nuclear Information System (INIS)

    Gai, M.

    1984-01-01

    The high spin states of 218 Ra exhibit a band of alternating parity states with enhanced E1 decay mode (B(E1) >=10 -2 W.u.). Various theoretical models are discussed, such as the octupole model, f and g boson model, second order E1 operator in IBA1 model, and the cluster model. The enhanced E1 deexcitation favors the cluster model. The low spin negative parity states lie on a J(J+1) trajectory contrary to the assumed vibrational character of the negative parity states in 218 Ra. A change in the character of states above the 11 - state is observed via a change in the moment of inertia and a decrease in the B(E1)/B(E2) branch ratios. Two quasi-particle 11 - states systematically occurring in the Ra-isotopes may be responsible for this change. The well known effect of loss of collectivity arising from two quasi-particle states, as observed in the hindrance of B(E2), is suggested to more dramatically hinder the B(E1) and lead to a reduction in the branch ratio B(E1)/B(E2). This observation suggests that the E1 enhancement is of collective character

This is acknowledged in consensus documents. The drug also has a good safety profile and a pharmacoeconomic advantage due to a reduction in the number of hospitalizations for asthma attacks. In recent years, some studies have shown that omalizumab is effective also in nonallergic asthma. Effects on the complex signaling mechanisms leading to activation of effector cells and to mediator release may account for this outcome. Indeed, omalizumab has been reported to be effective in a number of IgE-mediated and non-IgE-mediated disorders. Concerning the former, clinical efficacy has been observed in rhinitis, allergic bronchopulmonary aspergillosis, latex allergy, atopic dermatitis, allergic urticaria, and anaphylaxis. In addition, omalizumab has been demonstrated to be able to prevent systemic reactions to allergen immunotherapy, thus enabling completion of treatment in patients who otherwise would have to stop it. Concerning non-IgE-mediated disorders, omalizumab has been reported to be effective in nasal polyposis, autoimmune urticaria, chronic idiopathic urticaria, physical urticaria, idiopathic angioedema, and mastocytosis. Current indications for treatment with omalizumab are confined to severe allergic asthma. Consequently, any other prescription can only be off-label. However, it is reasonable to expect that the use of omalizumab will be approved for particularly important indications, such as anaphylaxis, in the near future

    We have searched for the reaction e + e - → τ + τ - bar ff, where f is either an electron, muon, or charged pion, at √s = 29 GeV using the Mark 2 detector at the PEP storage ring. One candidate event is found while 2.3 events are expected from known processes. We would expect to see 11 events if the cross-section for e + e - → τ + τ - bar ff at √s = 29 GeV were enhanced by the factor of 4.7 which the ALEPH collaboration reports for √s = 91 GeV. we also look for e + e - → e + e - bar ff and e + e - → μ + μ - bar ff, and for e + e - → τ + τ - γ using a similar analysis procedure and see the number of events predicted by the standard model. 10 refs., 5 figs., 3 tabs

    A large number of trials show that the anti-immunoglobulin (Ig) E antibody omalizumab is very effective in patients with severe allergic asthma. This is acknowledged in consensus documents. The drug also has a good safety profile and a pharmacoeconomic advantage due to a reduction in the number of hospitalizations for asthma attacks. In recent years, some studies have shown that omalizumab is effective also in nonallergic asthma. Effects on the complex signaling mechanisms leading to activation of effector cells and to mediator release may account for this outcome. Indeed, omalizumab has been reported to be effective in a number of IgE-mediated and non-IgE-mediated disorders. Concerning the former, clinical efficacy has been observed in rhinitis, allergic bronchopulmonary aspergillosis, latex allergy, atopic dermatitis, allergic urticaria, and anaphylaxis. In addition, omalizumab has been demonstrated to be able to prevent systemic reactions to allergen immunotherapy, thus enabling completion of treatment in patients who otherwise would have to stop it. Concerning non-IgE-mediated disorders, omalizumab has been reported to be effective in nasal polyposis, autoimmune urticaria, chronic idiopathic urticaria, physical urticaria, idiopathic angioedema, and mastocytosis. Current indications for treatment with omalizumab are confined to severe allergic asthma. Consequently, any other prescription can only be off-label. However, it is reasonable to expect that the use of omalizumab will be approved for particularly important indications, such as anaphylaxis, in the near future. PMID:24532966

    This descriptive cross-sectional study identified resources and programs that are available nationwide on the Internet to support individuals and families with intellectual and developmental disabilities (I/DD), with a focus on intellectual disability. This evaluation included easily identifiable information on specific resources and highlighted unique programs found in individual states that were linked from e-government websites. Researchers documented the ease of access and available information for all 50 states and the District of Columbia. A number of disparities and areas for improvement were recorded for states and I/DD websites. The researchers conclude that a number of additional health and support services will be needed to address the growing needs of this vulnerable population.

    Full Text Available Ever since Romania started its transition in the 1990s, it consistently scored poorly in various comparative performance assessments aimed at rating developing countries. In this paper we analyze whether Romania has managed to overcome the transition period or not, by pointing out both the drawbacks as well as the progress that has been made over the transition period, but most of all since our accession to the European Union in 2007. We discuss the concept of good governance for a new EU member state, by focusing on the state of public governance in Romania, but also addressing the other two important actors in the society, the private sector and the civil society.

    Full Text Available We applied resting-state functional magnetic resonance imaging (fMRI to examine the Apolipoprotein E (ApoE ε4 allele effects on functional connectivity of the default mode network (DMN and the salience network (SN. Considering the frequency specific effects of functional connectivity, we decomposed the brain network time courses into two bands: 0.01–0.027 Hz and 0.027–0.08 Hz. All scans were acquired by the Alzheimer’s Disease Neuroscience Initiative (ADNI. Thirty-two nondemented subjects were divided into two groups based on the presence (n=16 or absence (n=16 of the ApoE ε4 allele. We explored the frequency specific effects of ApoE ε4 allele on the default mode network (DMN and the salience network (SN functional connectivity. Compared to ε4 noncarriers, the DMN functional connectivity of ε4 carriers was significantly decreased while the SN functional connectivity of ε4 carriers was significantly increased. Many functional connectivities showed significant differences at the lower frequency band of 0.01–0.027 Hz or the higher frequency band of 0.027–0.08 Hz instead of the typical range of 0.01–0.08 Hz. The results indicated a frequency dependent effect of resting-state signals when investigating RSNs functional connectivity.

  1. First identification of the 0{sub 2}{sup +} state in {sup 30}Mg via its E0 transition

    Energy Technology Data Exchange (ETDEWEB)

    Schwerdtfeger, Wolfgang Norbert Erik

    2008-08-28

    The known 1789 keV level in {sup 30}Mg turned out to be a candidate for the 0{sub 2}{sup +} state due to its long lifetime of 3.9(4) ns and the absence of a {gamma} transition to the ground state. This triggered our search on the 0{sub 2}{sup +}{yields}0{sub 1}{sup +} E0 transition in {sup 30}Mg following the {beta} decay of {sup 30}Na: {beta} decay electrons were detected in a scintillation detector, while conversion electrons were focused onto a cooled Si(Li) detector using a Mini-Orange and detected with high resolution, which simultaneously suppresses the high background of {beta} decay electrons. Due to the large Q value of the {beta} decay of {sup 30}Na (17.3 MeV) the suppression of the coincident background induced by high-energy {gamma} rays and subsequently Compton-scattered electrons turned out to be the key challenge for the success of this experiment. In order to optimise the background suppression and thus the sensitivity to weak E0 transitions, offline test measurements using an {sup 90}Y and a {sup 152}Eu source were performed together with GEANT4 simulations. Resulting from these test measurements a highly sensitive experimental setup was designed and built, consequently minimising the amount of high-Z material in the target chamber, reducing X-ray production. As a by-product from test measurements the database value of the half-life of the 0{sub 2}{sup +} state in {sup 90}Zr could be corrected by more than 30 % to be t{sub 1/2}=41(1) ns. Finally, in a {beta} decay experiment at the ISOLDE facility at CERN the 0{sub 2}{sup +}{yields}0{sub 1}{sup +} E0 transition in {sup 30}Mg could be identified at the expected transition energy of 1788 keV proving for the first time shape coexistence at the borderline of the 'Island of Inversion'. This identification allows to determine the electric monopole strength as {rho}{sup 2}(E0)=26.2(7.5) x 10{sup -3}, indicating a rather weak mixing between the states in two potential minima in a simplified two

  3. Development of a two-state pellet injector for Heliotron-E

    International Nuclear Information System (INIS)

    1991-01-01

    This paper reports on a two-stage pellet injector for Heliotron-E that is constructed and tested. The aim is to increase pellet velocity for more flexible density profile control of the Heliotron-E plasma and also to conduct a pellet ablation study using a wider range of pellet velocity. The pellet velocity is limited to ∼1.4 km/s in the current six-pellet injector at Heliotron-E. The fundamental operation is simulated with the Quickgun code. The experimental results generally agree well (within 80 to 90%) with the code calculations. By using a newly developed high-pressure fast valve, a hydrogen pellet velocity of 3.2 km/s has been achieved, without a supportive shell or sabot to protect the pellet, although more tests are needed to confirm whether pellets can reliably be accelerated to this high speed without fracturing. The dependence of the pellet velocity and breech pressure on the pump tube fill pressure is studied. The results show that the fill pressure is an important parameter. The effect of the clearance between the piston and the pump tube wall on the pellet velocity is also investigated. The wear and damage of the piston caused by the compressing propellant gas are investigated. It is shown that changes on the piston surface when hydrogen is used for fill gas are different from the case of helium

    Full Text Available Este ensaio resgata algumas das principais discussões travadas na literatura das ciências sociais sobre as relações entre Estado, sociedade civil e participação social nas políticas de saúde. O recorte adotado é a dimensão política propriamente dita, deixando-se à parte - embora seja igualmente relevante - a participação da sociedade na provisão e produção de serviços de saúde. Os principais eixos de análise são as implicações sociais e políticas da opção pela perspectiva da pobreza ou da desigualdade; os movimentos sociais e os direitos sociais; e a relação Estado/sociedade num contexto de destituição de direitos. Privilegia-se a ótica da instituição da cidadania da perspectiva da justiça e da eqüidade social frente à diversidade e ao pluralismo que marcam as sociedades contemporâneas, em especial a brasileira, dadas as enormes desigualdades sociais que a caracterizam. A última sessão retoma de forma sucinta alguns dos principais traços que vêm marcando a experiência da participação social nos Conselhos de Saúde apontados pelas numerosas análises a respeito, sem no entanto se fazer um balanço dessa literatura quanto aos marcos teóricos e metodológicos aí presentes.The present essay in which the author seeks to reintroduce some of the main discussions within the social sciences literature on the relationship among state and civil society, and which can contribute for a reflection about social involvement in health policies. In this regard, the focus is on the political dimension proper of this relationship, putting aside - despite its relevance - society's participation on the provision of health services. The main axes of the analysis are the social and political implications in choosing the poverty or inequality perspective; social movements and social rights; and the state/society relationship in a context lacking basic rights. Attention is given to the institutionalization of citizenship

  5. Reversible Photoinduced Reductive Elimination of H2 from the Nitrogenase Dihydride State, the E(4)(4H) Janus Intermediate.

    We recently demonstrated that N2 reduction by nitrogenase involves the obligatory release of one H2 per N2 reduced. These studies focus on the E4(4H) "Janus intermediate", which has accumulated four reducing equivalents as two [Fe-H-Fe] bridging hydrides. E4(4H) is poised to bind and reduce N2 through reductive elimination (re) of the two hydrides as H2, coupled to the binding/reduction of N2. To obtain atomic-level details of the re activation process, we carried out in situ 450 nm photolysis of E4(4H) in an EPR cavity at temperatures below 20 K. ENDOR and EPR measurements show that photolysis generates a new FeMo-co state, denoted E4(2H)*, through the photoinduced re of the two bridging hydrides of E4(4H) as H2. During cryoannealing at temperatures above 175 K, E4(2H)* reverts to E4(4H) through the oxidative addition (oa) of the H2. The photolysis quantum yield is temperature invariant at liquid helium temperatures and shows a rather large kinetic isotope effect, KIE = 10. These observations imply that photoinduced release of H2 involves a barrier to the combination of the two nascent H atoms, in contrast to a barrierless process for monometallic inorganic complexes, and further suggest that H2 formation involves nuclear tunneling through that barrier. The oa recombination of E4(2H)* with the liberated H2 offers compelling evidence for the Janus intermediate as the point at which H2 is necessarily lost during N2 reduction; this mechanistically coupled loss must be gated by N2 addition that drives the re/oa equilibrium toward reductive elimination of H2 with N2 binding/reduction.

    It is a very well-known fact that an protonic exchange exists among natural DNA filaments and synthetic polynucleotides with the solvent (1--2). The existence of DNA open states, that is to say states for which the interior of the DNA molecule is exposed to the external environment, it has been demonstrated by means of proton-deuterium exchange (3). This work has carried out experiments measuring the dispersion of the traverse relaxation rate (4), as a pulsation rate function in a Carr-Purcell-Meiboom-Gill (CPMG) pulses sequence rate, to determine changes in the moist layer of the DNA molecule. The experiments were carried out under different experimental conditions in order to vary the probability that open states occurs, such as temperature or the exposure to electromagnetic fields. Some theoretical models were supposed to adjust the experimental results including those related to DNA non linear dynamic. [Spanish] Es un hecho bien conocido que existe un intercambio protonico entre filamentos naturales de ADN y polinucleotidos sinteticos con el solvente (1--2). La existencia de estados abiertos en el ADN, es decir estados para los cuales el interior de la molecula del ADN es expuesto al ambiente exterior, ha sido demostrado mediante experimentos de intercambio proton-deuterio (3). En el presente trabajo hemos realizado experimentos midiendo la dispersion de la tasa de relajacion transversal (4), como una funcion de la tasa de pulsacion en una secuencia de pulsos de Carr-Purcell-Meiboom-Gill (CPMG), para determinar cambios en la capa de hidratacion de la molecula de ADN. Los experimentos fueron realizados bajo diferentes condiciones experimentales para asi variar la probabilidad de que ocurran estados abiertos, tales como la temperatura o la exposicion a campos electromagneticos.

  8. Stato e società civile in Gramsci (State and Civil Society in Gramsci

    Directory of Open Access Journals (Sweden)

    Guido LIGUORI

    2016-06-01

    Full Text Available Gramsci is not, as at times has been said, the “theoretician of civil society”. Central to his reflections in the Prison Notebooks is instead the concept of the “integral State” or “extended State”, the dialectical union of State and civil society which allowed him to interpret the new social and political situation typical of much of the twentieth century. This new situation is characterized, on the one hand, by a new relationship between the economy and politics and, on the other, by the growing importance of the “apparatuses of consent” flanking the State’s traditional repressive apparatuses. For Gramsci the apparatuses of consent are sometimes public and sometimes apparently private but, in any case, their function is the same, namely to reinforce the hegemony of the dominant class, and to propagate a traditional common sense, thereby making it difficult to challenge the given set-ups of power. Since there has been a change in the State – the terrain of the struggle for power – the concept of revolution must also change: this is no longer an isolated insurrectionary event, as it was in the nineteenth century, but a long struggle for the conquest of “trenches and emplacements”, in other words the conquest of the centres that produce and extend consent.

    It was studied the peculiarity of the radionuclide intake to organism of amphibians and reptiles in the Poles'e radioecological reserve in 1997. The radioactive contamination level of investigated area was from 15 to 40 Ci/km 2 . It was measured 38 samples (26 for amphibians and 12 for reptiles) from points with background gamma-irradiation from 35 to 800 micro R/h. For the last eleven years of investigation it was revealed the total tendency to reduction of level of gamma-radioactive accumulation in 18,8-42,6 times for amphibians and in 2,8-52,5 times for reptiles

  10. Statistics of anomalously localized states at the center of band E = 0 in the one-dimensional Anderson localization model

    International Nuclear Information System (INIS)

    Kravtsov, V E; Yudson, V I

    2013-01-01

    We consider the distribution function P(|ψ| 2 ) of the eigenfunction amplitude at the center-of-band (E = 0) anomaly in the one-dimensional tight-binding chain with weak uncorrelated on-site disorder (the one-dimensional Anderson model). The special emphasis is on the probability of the anomalously localized states (ALS) with |ψ| 2 much larger than the inverse typical localization length ℓ 0 . Using the recently found solution for the generating function Φ an (u, ϕ) we obtain the ALS probability distribution P(|ψ| 2 ) at |ψ| 2 ℓ 0 ≫ 1. As an auxiliary preliminary step, we found the asymptotic form of the generating function Φ an (u, ϕ) at u ≫ 1 which can be used to compute other statistical properties at the center-of-band anomaly. We show that at moderately large values of |ψ| 2 ℓ 0 , the probability of ALS at E = 0 is smaller than at energies away from the anomaly. However, at very large values of |ψ| 2 ℓ 0 , the tendency is inverted: it is exponentially easier to create a very strongly localized state at E = 0 than at energies away from the anomaly. We also found the leading term in the behavior of P(|ψ| 2 ) at small |ψ| 2 ≪ ℓ −1 0 and show that it is consistent with the exponential localization corresponding to the Lyapunov exponent found earlier by Kappus and Wegner.

  14. Search for the standard model higgs boson in eτ final states

    Energy Technology Data Exchange (ETDEWEB)

    Howley, Ian James [Univ. of Texas, Arlington, TX (United States)

    2013-05-01

    Presented in this dissertation is a search for the standard model (SM) Higgs boson using the DØ detector at Fermilab in Batavia, IL. The SM is a fantastically accurate theory describing the fundamental interactions and particles of the Universe. The only undiscovered particle in the SM is the Higgs boson, which is hypothesized to be responsible for electroweak symmetry breaking and giving mass to all other particles. Considered in this search is the process H + X → eτhjj, where e is an electron, τh is the hadronic decay of a tau, and j is a jet, using p $\\bar{p}$ collisions at center of mass energy√s = 1.96 TeV. This search includes three production modes: associated production, gluon fusion and vector boson fusion. It also utilizes two decay channels: H→ ττ and H → WW. A new technique, dubbed the Global Boosted Decision Tree, is introduced which offers a means of providing continuity to a multivariate search as a function of a particular parameter, in this case, the mass of the Higgs boson. The observed (expected) limit on the ratio of cross section times branching fraction to the SM at 95% confidence level is 14.6 (16.0) at mH = 125 GeV. This result is combined with the related channel H + X → μτhjj and produced an observed (expected) limit of 9.0 (11.3) at mH = 125 GeV.

    This study assessed changes in levels of ever use, perceptions of harm from e-cigarettes and sociodemographic correlates of use among European Union (EU) adults during 2012-2014, as well as determinants of current use in 2014. We analysed data from the 2012 (n=26 751) and 2014 (n=26 792) waves of the adult Special Eurobarometer for Tobacco survey. Point prevalence of current and ever use was calculated and logistic regression assessed correlates of current use and changes in ever use, and perception of harm. Correlates examined included age, gender, tobacco smoking, education, area of residence, difficulties in paying bills and reasons for trying an e-cigarette. The prevalence of ever use of e-cigarettes increased from 7.2% in 2012 to 11.6% in 2014 (adjusted OR (aOR)=1.91). EU-wide coefficient of variation in ever e-cigarette use was 42.1% in 2012 and 33.4% in 2014. The perception that e-cigarettes are harmful increased from 27.1% in 2012 to 51.6% in 2014 (aOR=2.99), but there were major differences in prevalence and trends between member states. Among those who reported that they had ever tried an e-cigarette in the 2014 survey, 15.3% defined themselves as current users. Those who tried an e-cigarette to quit smoking were more likely to be current users (aOR=2.82). Ever use of e-cigarettes increased during 2012-2014. People who started using e-cigarettes to quit smoking tobacco were more likely to be current users, but the trends vary by country. These findings underscore the need for more research into factors influencing e-cigarette use and its potential benefits and harms. Published by the BMJ Publishing Group Limited.

    The United States of America comprise an area so vast in extent and so diverse in natural features as well as in characters due to human agency that the American citizen who knows thoroughly his own country must have traveled widely and observed wisely. To 'know America first' is a patriotic obligation, but to meet this obligation the railroad traveler needs to have his eyes directed toward the more important or essential things within his field of vision and then to have much that he sees explained by what is unseen in the swift passage of the train. Indeed, many things that attract his attention are inexplicable except as the story of the past is available to enable him to interpret the present. Herein lie the value and the charm of history, whether human or geologic. The present stimulus given to travel in the home country will encourage many thousands of Americans to study geography at first hand. To make this study most profitable the traveler needs a handbook that will answer the questions that come to his mind so readily along the way. Furthermore, the aim of such a guide should be to stimulate the eye in the selection of the essentials in the scene that so rapidly unfolds itself in the crossing of the continent. In recognition of the opportunity to render service of this kind to an unusually large number of American citizens, as well as to visitors from other countries, the United States Geological Survey has published a series of guidebooks covering four of the older railroad routes west of the Mississippi. The present volume is an addition to this series and covers one of the finest scenic routes of the continent. These books are educational in purpose, but the method adopted is to entertain the traveler by making more interesting what he sees from the car window. The plan of the series is to present authoritative information that may enable the reader to realize adequately the scenic and material resources of the region he is traversing, to comprehend

    The E 2 /M 1 multipole mixing ratio δ1 →2 of the 1sc+→21+ γ -ray decay in 156Gd and hence the isovector E 2 transition rate of the scissors mode of a well-deformed rotational nucleus has been measured for the first time. It has been obtained from the angular distribution of an artificial quasimonochromatic linearly polarized γ -ray beam of energy 3.07(6) MeV scattered inelastically off an isotopically highly enriched 156Gd target. The data yield first direct support for the deformation dependence of effective proton and neutron quadrupole boson charges in the framework of algebraic nuclear models. First evidence for a low-lying Jπ=2+ member of the rotational band of states on top of the 1+ band head is obtained, too, indicating a significant signature splitting in the K =1 scissors mode rotational band.

    The E2/M1 multipole mixing ratio δ_{1→2} of the 1_{sc}^{+}→2_{1}^{+} γ-ray decay in ^{156}Gd and hence the isovector E2 transition rate of the scissors mode of a well-deformed rotational nucleus has been measured for the first time. It has been obtained from the angular distribution of an artificial quasimonochromatic linearly polarized γ-ray beam of energy 3.07(6) MeV scattered inelastically off an isotopically highly enriched ^{156}Gd target. The data yield first direct support for the deformation dependence of effective proton and neutron quadrupole boson charges in the framework of algebraic nuclear models. First evidence for a low-lying J^{π}=2^{+} member of the rotational band of states on top of the 1^{+} band head is obtained, too, indicating a significant signature splitting in the K=1 scissors mode rotational band.

    With an exactly solvable O(4) model of Piepenbring, Silvestre-Brac and Szymanski, we demonstrate that the attenuation factor for the B(E2) values, derived by the lowest-order approximation of the multiphonon method, takes excellent care of the kinematical anharmonicity effects, if multiphonon states are defined in the intrinsic subspace orthogonal to the pairing rotation. It is also shown that the other attenuation effect characterizing the interacting boson model is not a dominant effect in the model analysed here.

    Full Text Available A cross-sectional study in Nigeria was undertaken to determine the epidemiology, seroprevalence, and associated risk factors, of hepatitis E virus (HEV. A total of 462 subjects were used for the study, categorized into four groups: apparently healthy persons, pregnant women, HIV positive subjects, and animal handlers. Information was obtained from subjects using interviewer-administered questionnaire. Blood samples were collected and analyzed for HEV antibodies (IgG and IgM using enzyme-linked immunosorbent assay (ELISA technique. Results obtained were analyzed using Statistical Package for Social Sciences (SPSS version 17.0 statistical software. The overall seroprevalence of IgG and IgM was 42.7 and 0.9%, respectively. Animal handlers had the highest seroprevalence (66.7%. The associated risk factors for IgM seroprevalence were rural dwelling ( P = 0.039, odds ratio (OR 3.3, 95% confidence interval (CI 0.7–15.4, blood transfusion ( P < 0.001, OR 9.6, 95% CI 2.6–35.6, attending to animals ( P = 0.032, OR 4.9, 95% CI 0.9–26.6, and waste disposal ( P < 0.001.

    The microquasar 1E1740.7-2942, also known as the 'Great Annihilator,' was observed by NuSTAR in the summer of 2012. We have analyzed in detail two observations taken ∼2 weeks apart, for which we measure hard and smooth spectra typical of the low/hard state. A few weeks later the source flux declined significantly. Nearly simultaneous coverage by INTEGRAL is available from its Galactic Center monitoring campaign lasting ∼2.5 months. These data probe the hard state spectrum from 1E1740.7-2942 before the flux decline. We find good agreement between the spectra taken with IBIS/ISGRI and NuSTAR, with the measurements being compatible with a change in flux with no spectral variability. We present a detailed analysis of the NuSTAR spectral and timing data and upper limits for reflection of the high energy emission. We show that the high energy spectrum of this X-ray binary is well described by thermal Comptonization.

    Following the breakup of the communist era, Eastern-Central Europe's transformation states had initiated E and P licensing processes, inviting non-state, western oil companies to apply for license rights. Offers ranged from reconnaissance to EOR license rights. Oil companies and government authorities expected the new era to yield success, for a variety of reasons. The opportunities offered attracted in particular and increasingly independent and niche-player companies. E and P activities were particularly successful, in terms of having discovered economically viable oil and gas reserves and having achieved incremental production, in Poland, Lithuania, Hungary, the Czech Republic and Romania. Newcomers were involved in the latter four countries. Field reserve sizes, both for oil and gas, are moderate to small; such fields are also expected to contribute mainly to future reserve replacement of the region. The involvement of small-size companies, which have found the means to also make smaller fields economically viable, will support this. (orig.)

    Full Text Available The purpose of the article is to develop the diagnostics of the system of public e-procurement in terms of the risks of its subjects and to develop an approach to minimize the risk associated with changes in the purchase price. It is determined that the most widespread risks in the public e-procurement system in Ukraine, classified on the basis of a subjective approach, are: 1 a conspiracy of participants in the tender process; 2 insufficient level of professionalism; 3 change of purchase price. It has been determined that risk management in the system of public e-procurement should be understood as the diagnostic process (identification, analysis, evaluation, prevention, minimization and elimination of the risks of the customer, supplier and common risks in the stages of post-accession, tender and post-tandem procedures in order to balance financial and legal interests of the state and business. It is established that calculation of the correction of the purchase price (taking into account macroeconomic fluctuations should take into account the following elements (components: 1 commodity-material element (direct commodity-material expenses as of the base date (opening of a tender offer and on the date of delivery or start of implementation of the state order; 2 the human element (labor costs (average wage, qualification upgrading by the base date (opening a tender offer and as of the date of delivery or start of execution of the state order; 3 an element related to other attendance costs (costs of bank servicing of payments, the amount of duty in the case of export-import operations, logistics costs as of the base date (opening a tender offer and as of the date of delivery or start of execution of the state order; 4 fixed item (percentage in % of purchase price. The prospect of further research in this direction is to improve the system of polycriterial diagnostics of the activities of enterprises, taking into account the presented research

    The prevalence of electronic cigarette (e-cigarette) use is increasing. Population health effects will depend on cigarette smoking behaviors, levels of dual use with conventional cigarettes, and e-cigarette toxicity. To evaluate potential health effects of various scenarios of increasing promotion and use of e-cigarettes. A base case model was developed using data on actual cigarette and e-cigarette use patterns that quantifies transitions from an initial state of no cigarette or e-cigarette use to 1 of 5 final states: never use of cigarettes or e-cigarettes, cigarette use, e-cigarette use, dual use of cigarettes and e-cigarettes, or quit. Seven scenarios were created that cover a range of use patterns, depending on how the e-cigarette market might develop, as well as a range of possible long-term health effects of e-cigarette use. Scenarios for changes from the base case were evaluated using Monte Carlo simulations. Separate sets of base case model parameters were evaluated for the US and UK populations. We assigned unitless health "costs" for each final state on a scale of 0 to 100. Population health "costs" were compared with the base case (status quo) assuming e-cigarette use health "costs" from 1% to 50% as dangerous as conventional cigarette use health costs. Compared with the base case, a harm reduction scenario in which e-cigarette use increases only among smokers who are interested in quitting with more quit attempts and no increased initiation of e-cigarette use among nonsmokers, and another scenario in which e-cigarettes are taken up only by youth who would have smoked conventional cigarettes, had population-level health benefits regardless of e-cigarette health costs in both the United States and United Kingdom. Conversely, scenarios in which e-cigarette promotion leads to renormalization of cigarette smoking or e-cigarettes are used primarily by youth who never would have smoked showed net health harms across all e-cigarette health costs.

Até o momento não existem estudos clínicos que comprovem a eficácia e a segurança deste procedimento; apenas pesquisas experimentais com resultados questionáveis, tanto em seres humanos quanto em animais. Nos últimos anos, a área de Vigilância Sanitária (VS do Ministério da Saúde ampliou suas ações preventivas e de controle de riscos tanto no âmbito privado como coletivo. As ações da VS têm, muitas vezes, como base o poder legal de polícia administrativa que a legislação lhe confere.

    Several new methods of in-beam conversion-electron and γ-ray spectrometry, applicable in the determination of E0 and E2 decay properties of low-lying 0 + states in even-mass nuclei, have been developed. The main attention has been paid to direct lifetime-measurement and coincidence methods based on the use of the natural pulsing of a cyclotron beam. With the aid of these methods, the similarity of the absolute decay rates of the two-neutron-hole 0 + 2 states in the N = 124 nuclei 206 Pb and 208 Po has been shown. A systematic investigation of the de-excitation of the 0 + 2 and 0 + 3 states in 112 , 11 4 , 116 , 118 , 120 Sn has been carried out. Twelve E0 transitions connecting the 0 + states have been observed, including very strong low-energy E0 transitions between the excited 0 + states, and several absolute transition probabilities have been determined. Furthermore, the new techniques have been applied successfully in determining the absolute E0 and E2 transition rates from the 0 + 2 and 0 + 3 states in 112 Cd and 114 Cd. The use of isotope-shift data in the calculation of the monopole strengths in 206 Pb and 208 Po is discussed. The results on even Sn and Cd nuclei are discussed within the framework of the coexistence of different shapes and of configuration mixing. (author)

    Na(+),K(+)-ATPase pumps three Na(+) ions out of cells in exchange for two K(+) taken up from the extracellular medium per ATP molecule hydrolysed, thereby establishing Na(+) and K(+) gradients across the membrane in all animal cells. These ion gradients are used in many fundamental processes, notably excitation of nerve cells. Here we describe 2.8 Å-resolution crystal structures of this ATPase from pig kidney with bound Na(+), ADP and aluminium fluoride, a stable phosphate analogue, with and without oligomycin that promotes Na(+) occlusion. These crystal structures represent a transition state preceding the phosphorylated intermediate (E1P) in which three Na(+) ions are occluded. Details of the Na(+)-binding sites show how this ATPase functions as a Na(+)-specific pump, rejecting K(+) and Ca(2+), even though its affinity for Na(+) is low (millimolar dissociation constant). A mechanism for sequential, cooperative Na(+) binding can now be formulated in atomic detail.

    Influence of radiation on important ecological and physiological characteristics of Pinus silvestris L., Phleum pratense L. and Dactylis glomerata L. growing on territory of the Poles'e State Radiation Ecological Reservation has been investigated in 1992-1994. Significant changes in species and quantitative formation of natural vegetation growing on territory contaminated by the Chernobyl accident release were not observed. Positive correlation between the content of protein in needles of Pinus silvestris L., leaves of Agropyron repens L. and specific radioactivity of photosystem was established. Positive correlation between specific radioactivity of overground photosystem and quantity of nucleic acids (DNA+RNA) is leaves of Dactylis glomerata was found. 8 refs., 2 tabs., 2 figs

    To examine the association between state-level tobacco control measures and current use estimates of both e-cigarettes and cigarettes, while accounting for socio-demographic correlates. Using the 2012-2013 and 2013-2014 National Adult Tobacco Survey (NATS), we assessed prevalence estimates of US adults' e-cigarette and cigarette current use. Four state groups were created based on the combined state-specific prevalence of both products: low cigarette/e-cigarette (n = 15), high cigarette/e-cigarette (n = 16), high cigarette/low e-cigarette (n = 11), and low cigarette/high e-cigarette) (n = 9). To evaluate the implementation of state-level tobacco control measures, Tobacco Control Index (TCI) was calculated using the State of Tobacco Control annual reports for 2012 and 2013. Multinomial logistic regression models were used to examine differences among the four groups on socio-demographic factors and TCI. Low cigarette/e-cigarette group was used as the referent group. Current use estimates of each product varied substantially by state; current e-cigarette use was highest in Oklahoma (10.3%) and lowest in Delaware (2.7%), and current cigarette use was highest in West Virginia (26.1%), and lowest in Vermont (12.6%). Compared to low cigarette/e-cigarette, all other US-state categories had significantly lower TCI scores (high cigarette/e-cigarette: adjusted Relative Risk Ratio [aRRR] = 0.61; 95% confidence interval [CI]: 0.60-0.61, high cigarette/low e-cigarette: aRRR = 0.74; 95% CI: 0.73-0.74, and low cigarette/high e-cigarette: aRRR = 0.72; 95% CI: 0.71-073). Enforcing existing tobacco control measures likely interacts with e-cigarette use despite being cigarette-focused. Continuing to monitor e-cigarette use is critical to establish baseline use and evaluate future e-cigarette specific federal and state-level tobacco regulatory actions while accounting for the existing tobacco control environment. This study investigates state-level current use estimates of e

A enfermidade apresenta como característica principal a formação de lesões com aspecto granulomatoso nos hospedeiros. Neste trabalho, relatou-se a ocorrência da pitiose em ovinos nos estados de Pernambuco (PE e Bahia (BA, Nordeste do Brasil, bem como foi avaliada a eficácia de um imunoterápico frente a esta enfermidade. Amostras de sangue de 53 ovinos foram coletadas, sendo 49 animais oriundos de propriedades localizadas em PE e quatro animais provenientes da BA. Sete ovinos demonstraram sinais clínicos de pitiose ovina. Um dos animais foi submetido à eutanásia e sua cabeça e linfonodo submandibular foram coletados e enviados para análises laboratoriais. Seis ovinos foram submetidos à imunoterapia, sendo mantidos nas instalações do setor de ovinocultura da Univasf/Petrolina-PE durante o tratamento. As técnicas de ELISA, cultura fúngica e reação em cadeia da polimerase (PCR foram utilizadas como métodos diagnósticos da pitiose ovina, sendo eficientes para confirmação dos casos clínicos no rebanho.

    1.1 This test method describes the use of solid-state track recorders (SSTRs) for neutron dosimetry in light-water reactor (LWR) applications. These applications extend from low neutron fluence to high neutron fluence, including high power pressure vessel surveillance and test reactor irradiations as well as low power benchmark field measurement. (1) This test method replaces Method E 418. This test method is more detailed and special attention is given to the use of state-of-the-art manual and automated track counting methods to attain high absolute accuracies. In-situ dosimetry in actual high fluence-high temperature LWR applications is emphasized. 1.2 This test method includes SSTR analysis by both manual and automated methods. To attain a desired accuracy, the track scanning method selected places limits on the allowable track density. Typically good results are obtained in the range of 5 to 800 000 tracks/cm2 and accurate results at higher track densities have been demonstrated for some cases. (2) Trac...

  15. Splitting sensitivity of the ground and 7.6 eV isomeric states of 229Th

    The lowest-known excited state in nuclei is the 7.6 eV isomer of 229 Th. This energy is within the range of laser-based investigations that could allow accurate measurements of possible temporal variation of this energy splitting. This in turn could probe temporal variation of the fine-structure constant or other parameters in the nuclear Hamiltonian. We investigate the sensitivity of this transition energy to these quantities. We find that the two states are predicted to have identical deformations and thus the same Coulomb energies within the accuracy of the model (viz., within roughly 30 keV). We therefore find no enhanced sensitivity to variation of the fine-structure constant. In the case of the strong interaction the energy splitting is found to have a complicated dependence on several parameters of the interaction, which makes an accurate prediction of sensitivity to temporal changes of fundamental constants problematical. Neither the strong- nor Coulomb-interaction contributions to the energy splitting of this doublet can be constrained within an accuracy better than a few tens of keV, so that only upper limits can be set on the possible sensitivity to temporal variations of the fundamental constants

    Differential cross sections have been measured for elastic and inelastic scattering of electrons by ground-state helium at 29.6 and 40.1eV. The normalisation of the cross sections is discussed. Theoretical cross sections have been obtained using a 10-state coupled-channels-optical calculation. In general, there is good agreement between theory and experiment for singlet states but not for triplet. 20 refs., 5 tabs., 6 figs

    Electron-photon angular correlations have been measured for excitation of the 2P state of hydrogen at incident energies of 55 and 100 eV. The data presented extend the results of Weigold and co-workers (Flinders Univ. preprint (1980)) to smaller scattering angles and reveal the existence of a deep minimum in the parameter lambda thetasub(e) = 10 0 at and incident electron energy of 100 eV.

    Full Text Available Com a noção de governamentalidade, Foucault refletiu sobre a constituição do Estado moderno e suas tecnologias de condução da vida da população. Discutimos neste texto a relação entre Estado brasileiro, movimentos sociais LGBT (lésbicas, gays, bissexuais, travestis e transexuais e a elaboração de políticas curriculares para a inclusão social e jurídica daquela população. Nossa hipótese é que o processo de governamentalização dessa população específica, a despeito de garantir avanços antidiscriminatórios, tem como consequência colateral o aprisionamento dos próprios movimentos sociais LGBT e das políticas educacionais a eles relacionados numa lógica identitária e normalizadora, que tende a pacificar suas demandas e arrefecer sua capacidade de crítica e autocrítica. Finalmente, recorremos à noção foucaultiana de estética da existência e de atitude queer para pensar novas formas de resistência pós-identitária

  1. Decadal changes in the CaCO3 saturation state along 179°E in the Pacific Ocean

    To assess degrees of ocean acidification, we mainly investigated decadal changes in the saturation state of seawater with respect to aragonite (Ωarg), which is a more vulnerable mineral form of CaCO3, along the 179°E meridian (WOCE P14N) in the Pacific Ocean. We found a maximum decrease of Ωarg of -0.48 (-0.034 a-1) at 200-300 dbar (isopycnal surfaces of 24.0-25.8 kg m-3) at 20°N. Between 1993 and 2007, the saturation horizon rose by 17 dbar (1.2 dbar a-1) at latitudes 10°N-50°N. Although ΔΩarg mostly reflected changes in normalized dissolved inorganic carbon (ΔnCT), it was larger than could be explained by anthropogenic CO2 storage alone. Decomposition of ΔnCT revealed that ΔΩarg was enhanced by approximately 50% by a non-anthropogenic CO2 contribution represented by changes in apparent oxygen utilization. Our results suggest that ocean acidification can be temporarily accelerated by temporal changes in oceanic conditions.

    Cloud computing is emerging as a new computing paradigm in the healthcare sector besides other business domains. Large numbers of health organizations have started shifting the electronic health information to the cloud environment. Introducing the cloud services in the health sector not only facilitates the exchange of electronic medical records among the hospitals and clinics, but also enables the cloud to act as a medical record storage center. Moreover, shifting to the cloud environment relieves the healthcare organizations of the tedious tasks of infrastructure management and also minimizes development and maintenance costs. Nonetheless, storing the patient health data in the third-party servers also entails serious threats to data privacy. Because of probable disclosure of medical records stored and exchanged in the cloud, the patients' privacy concerns should essentially be considered when designing the security and privacy mechanisms. Various approaches have been used to preserve the privacy of the health information in the cloud environment. This survey aims to encompass the state-of-the-art privacy-preserving approaches employed in the e-Health clouds. Moreover, the privacy-preserving approaches are classified into cryptographic and noncryptographic approaches and taxonomy of the approaches is also presented. Furthermore, the strengths and weaknesses of the presented approaches are reported and some open issues are highlighted.

    B(E2, L+2-->L) transitions in the sdg interacting boson model SU(3) limit are studied with a general E2 transition operator. Analytical expressions are obtained using a group theoretic method. It is found that when using transition operators of the form (d†g~+g†d~)2 or (g†g~)2, the B(E2, L+2-->L) values in the ground-state band have an L(L+3) dependent term. As L increases, the B(E2) values can be larger than the rigid rotor model value. Application to 236,238U is discussed.

    A search is performed for production of short-lived particles in e+e- -> XY, with X -> gamma gamma and Y -> ffbar, for scalar X and scalar or vector Y. Model-independent limits in the range of 25-60 femtobarns are presented on sigma (e+e- -> XY) x B(X -> ffbar) for centre-of-mass energies in the range 205-207 GeV. The data from all LEP centre-of-mass energies 88-209 GeV are also interpreted in the context of fermiophobic Higgs boson models, for which a lower mass limit of 105.5 GeV is obtained for a "benchmark" fermiophobic Higgs boson.

    Exploration Vessel (E/V) Nautilus has been mapping the seafloor off the west coast of the United States, from Washington to California, for the past three years with a Kongsberg EM302 multibeam sonar. This system simultaneously collects bathymetry, seafloor and water column backscatter data, allowing an integrated approach to mapping to more completely characterize a region, and has identified over 1,000 seafloor seeps. Hydrographic multibeam sonars like the EM302 were designed for mapping the bathymetry. It is only in the last decade that major mapping projects included an integrated approach that utilizes the seabed and water column backscatter information in addition to the bathymetry. Nautilus mapping in the Eastern Pacific over the past three years has included a number of seep-specific expeditions, and utilized and adapted the preliminary mapping guidelines that have emerged from research. The likelihood of seep detection is affected by many factors: the environment: seabed geomorphology, surficial sediment, seep location/depth, regional oceanography and biology, the nature of the seeps themselves: size variation, varying flux, depth, and transience, the detection system: design of hydrographic multibeam sonars limits use for water column detection, the platform: variations in the vessel and operations such as noise, speed, and swath overlap. Nautilus integrated seafloor mapping provided multiple indicators of seep locations, but it remains difficult to assess the probability of seep detection. Even when seeps were detected, they have not always been located during ROV dives. However, the presence of associated features (methane hydrate and bacterial mats) serve as evidence of potential seep activity and reinforce the transient nature of the seeps. Not detecting a seep in the water column data does not necessarily indicate that there is not a seep at a given location, but with multiple passes over an area and by the use of other contextual data, an area may

    The process e+ e- -> n gamma with n>=2 is studied at centre-of-mass energies ranging from \\root(s)=192 to 208 GeV. The data sample corresponds to a total integrated luminosity of 427 1/pb. The total and differential cross sections are found to be in agreement with the QED expectations. Using all the data collected with the L3 detector above the Z pole, limits on deviations from QED, excited electrons, contact interactions, extra space dimensions and excited spin-3/2 leptons are set.

  8. [Pediatric drug development: ICH harmonized tripartite guideline E11 within the United States of America, the European Union, and Japan].

    2014-10-01

    To address the lack of appropriate pediatric drugs available on the global market, in 2000 the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) issued the ICH E11 guideline regarding the Clinical Investigation of Medicinal Products in the Pediatric Population. This guideline considerably changes the environment of drug development for children. It has been written specifically to harmonize, promote, and facilitate high-quality and ethical clinical research for children within the ICH regions, i.e., the United States of America (USA), the European Union (EU), and Japan. This article details the various regulations applicable in each ICH region following the publication of the guideline. The framework of rewards, incentives, and obligations for pharmaceutical companies established for the development of pediatric drugs are compared. It appears that the USA and the EU have both developed specific regulations for pediatric drug development while Japan has not. However, in Japan, pharmaceutical companies (PCs) are encouraged to develop pediatric drugs voluntarily, and they may be granted additional months of market exclusivity or the postponement of the drug re-examination deadline. In both the USA and the EU, regulations aimed to increase the number of clinical studies conducted in children, in order to ensure that the necessary data are generated, determining the conditions in which a drug may be authorized to treat the pediatric population. PCs are encouraged to develop pediatric assessment, including pediatric clinical trials, which is described in a pediatric plan submitted to the relevant authorities. A system of rewards for PCs submitting an application for marketing authorization containing pediatric use information has been put in place to cover the additional investment for testing drugs in children. Subject to conditions, these rewards consist in a 6-month extension of the patent or

    By using complete diagonalization method, the zero-field splitting and g factors of the ground 4A2 and the first excited 2E states of Cr 3+ ions in emerald are calculated. The theoretical results are in good agreement with the experimental data. The dependencies of the g factors on the crystal field parameters, including Dq, v, and v', have been studied. It is shown that, the g factors of the ground state varied with the crystal field parameters approximately in a linear way, but the g factors of the first excited state varied nonlinearly with these parameters.

    This on-line experiment examined whether the addition of ingredient- or industry-themed warning statements in television advertisements for e-cigarettes would affect young adults' craving for and risk perceptions of e-cigarettes and combustible cigarettes, as well as intent to purchase e-cigarettes. Advertisements for two leading e-cigarette brands were edited to contain a warning statement about product ingredients or about the tobacco industry. Participants were assigned randomly to one of eight treatments or one of two brand-specific control conditions without any warning statement. Young adults (n=900, aged 18-34 years) in a web panel were recruited from three groups: recent e-cigarette users, current smokers who used combustible cigarettes exclusively and non-users of either product. Craving and risk perceptions (addictiveness, harmful to health in general, harmful to others) were measured separately for e-cigarettes and combustible cigarettes. The Juster scale measured intention to purchase e-cigarettes. Exposure to both types of warnings was associated with lower craving for e-cigarettes among e-cigarette users and smokers who experienced any craving (Paddictive than the control conditions (Pe-cigarette television advertising similarly reduces craving and purchase intent for e-cigarettes, but has inconsistent effects on perceived risks. © 2015 Society for the Study of Addiction.

    Full Text Available Purpose – This essay analyzes the legitimacy of norms produced by the state’s regulatory activity. Underpinnings of the regulatory state and regulatory activity are discussed from the viewpoint of theories that might explain the legitimacy of its normative production, not least the administrative state theory of Dwight Waldo, who defends a government by technicians, valuing expertise. Methodology/approach/design – In the first section, the paper presents concepts of regulation and regulatory state. After that, the paper introduces the underpinnings for legitimate production of norms and the concept of public administration is addressed from the perspectives of the theory proposed by Dwight Waldo. Findings – According to Dwight Waldo, the legitimacy of regulatory decisions taken by a bureaucratic body relies on the technical expertise of its members, admitted through a meritocratic state choice.

    The four-jet final state is analyzed to search for hadronic decays of pair-produced heavy particles. The analysis uses the ALEPH data collected at LEP in November 1995 at centre-of-mass energies of 130 and 136~GeV, corresponding to a total integrated luminosity of 5.7~\\inpb. An excess of four-jet events is observed with respect to the standard model predictions. In addition, these events exhibit an enhancement in the sum of the two di-jet masses around 105~\\Gcs. The properties of these events are studied and compared to the expectations from standard processes and to pair production hypotheses.

    The United States is the largest producer and consumer of diatomite in the world. In 2001, the United States produced about a third of the estimated global production of 1.95 million metric tons (Mt) of diatomite (Dolley, 2003). In any given year, the United States accounts for at least 50 percent of all the diatomite exported in the world (Roskill, 1994). Seven diatomite companies operating in the United States produce diatomite in various grades for a range of applications, including filtration, absorbents, fillers, insulation, and cement manufacture. Economic deposits of diatomite within the United States depend on variations in the physical and chemical properties between and within deposits, potential end uses, and proximity to suitable markets. On the basis of historical production figures, estimated U.S. diatomite-production capacity is currently about 800,000 metric tons per year (t/yr).

    Full Text Available One of the most representative wetlands Cauca Valley State is the one called “Gota e’ Leche”, located in the town of Yotoco. This ecosystem is important because it is the habitat of many species of animals and native plants. The region where is located is a tropical dry forest (Bs-T (HOLDRIDGE, 1978. The wetland has had numerous trophic changes because the anthropogenic activities carry on the area (sugar mills, farmers, etc., This study determined the trophic state of the wetland using biological parameters such as primary productivity, chlorophyll, riparian flora and aquatic macro invertebrates, as well as physical and chemical such as water temperature, salinity, dissolved gases and others. According to our data, we determined that the wetland has a eutrophic state prone to hyper eutrophication. The system is continuously subjected to disturbance by human activities that change the characteristics of the ecosystem. As an indicator of this change, it is noticeable that in some sectors the marshy vegetation shows succession process belonging to a transition between aquatic and terrestrial ecosystems. For this reason, it is important the get more and meaningful knowledge of their successional stage in order to implement actions that will enable their restoration and conservation.

    The literature has shown that tobacco use causes damage to the health of cigarette users, manifesting itself in diseases with high mortality. Among these diseases include respiratory failure, pulmonary emphysema and lung cancer, among others. On the other hand, smoking contributes significantly to increasing the dose of natural radiation received by man, due to the presence of uranium series radionuclides, such as 226 Ra, 210 Pb and 210 Po, in relatively high concentrations in fresh tobacco leaves. The determination of these radionuclides in this matrix is of great interest, once they can be incorporated not only by the active smoker, but also by the passive smoker. The results of this study confirmed the significant presence of 226 Ra and 210 Pb in tobacco samples collected and analyzed. The average values of activity concentration found in samples from the State of Alagoas were of Bq.kg -1 0.8 to 210 Pb and 183.5 Bq.kg -1 to 226 Ra. For samples coming from the State of Rio Grande do Sul, these values were 4,0 Bq.kg -1 to 210 Pb and 161.3 Bq.kg -1 to 226 Ra

    Full Text Available Neste artigo, primeiramente, será discutido, ainda que de maneira breve, o processo e a implicação do acordo do pós-Estado do Bem-Estar para o Estado, para o capital, para as instituições do setor público e para os cidadãos. Uma das principais questões na análise desse processo está baseada em dois pontos relacionados: a privatização e a mercantilização do setor público são crescentemente complexas e totalizadoras e formam parte de um novo acordo político global. Os valores do mercado privado são celebrados em quase todos os Estados do ocidente, dando legitimação e impulso para certas ações e compromissos - espírito empresarial, competição e excelência -, e inibindo e deslegitimando outros - justiça social, eqüidade, tolerância. Em particular, este trabalho tenta enfatizar a inserção de hábitos da produção privada, e de suas sensibilidades comerciais e "moral utilitária", na prática educacional.In this article, firstly, it will be discussed briefly the process and the implication of the Post-Welfare State settlement for the State, for capital, for public sector institutions and for citizen. One of the main questions in the analysis of this process is based in two related points: that privatisation and commodification in the public sector is increasingly complex and increasingly totalizing and they form part of a new global political settlement. The values of the private market are celebrated by the States of almost all western societies give legitimation and impetus to certain actions and commitments - enterprise, competition, excellence - and inhibit and de-legitimize others - social justice, equity, tolerance. In particular this paper tries to emphasize the insertion of the habitus of private production and its commercial sensibilities and "utilitarian morality" into educational practices.

    A search is described for the generic process e+e- to X Y, where X is a neutral heavy scalar boson decaying into a pair of photons, and Y is a neutral heavy boson (scalar or vector) decaying into a fermion pair. The search is motivated mainly by the cases where either X, or both X and Y, are Higgs bosons. In particular, we investigate the case where X is the Standard Model Higgs boson and Y the Z0 boson. Other models with enhanced Higgs boson decay couplings to photon pairs are also considered. The present search combines the data set collected by the OPAL collaboration at 189 GeV collider energy, having an integrated luminosity of 182.6pb-1, with data samples collected at lower energies. The search results have been used to put 95% confidence level bounds, as functions of the mass of X, on the product of the cross-section and the relevant branching ratios, both in a model independent manner and for the particular models considered.

    The four-jet final state is analyzed to search for hadronic decays of pair-produced heavy particles. The analysis uses the ALEPH data collected at LEP in November 1995 at centre-of-mass energies of 130 and 136 GeV, corresponding to a total integrated luminosity of 5.7 pb-1. An excess of four-jet events is observed with respect to the standard model predictions. In addition, these events exhibit an enhancement in the sum of the two di-jet masses around 105 GeV/ c 2. The properties of these events are studied and compared to the expectations from standard processes and to pair production hypotheses.

    We investigated the relationship between receptivity to electronic cigarette (e-cigarette) advertisements at baseline and e-cigarette use at follow-up among adult baseline non-users of cigarettes and e-cigarettes. A nationally representative online panel was used to survey non-users of cigarettes and e-cigarettes ( n  = 2191) at baseline and 5-month follow-up. At baseline, respondents were shown an e-cigarette advertisement and asked if they were aware of it (exposure). Among those exposed, receptivity was self-rated for each ad using a validated scale of 1 to 5 for agreement with each of six items: "worth remembering," "grabbed my attention," "powerful," "informative," "meaningful," and "convincing." Logistic regression was used to measure the relationship between receptivity at baseline and e-cigarette use at follow-up. Among baseline non-users of cigarettes and e-cigarettes, 16.6% reported exposure to e-cigarette advertisements at baseline; overall mean receptivity score was 2.77. Among baseline non-users who reported exposure to e-cigarette advertisements, incidence of e-cigarette use at follow-up was 2.7%; among baseline non-users who reported not being exposed to e-cigarette advertisements, incidence of e-cigarette use at follow-up was 1.3%. The attributable risk percentage for e-cigarette initiation from e-cigarette advertisement exposure was 59.3%; the population attributable risk percentage from e-cigarette advertisement exposure was 22.6%. Receptivity at baseline was associated with e-cigarette use at follow-up (aOR = 1.57; 95% CI = 1.04-2.37). Receptivity to e-cigarette advertisements at baseline was associated with greater odds of e-cigarette use at follow-up among baseline non-users of cigarettes and e-cigarettes. Understanding the role of advertising in e-cigarette initiation could help inform public health policy.

    Growing pigs (n=21)at an initial liveweight of 30 kg were divided into three groups of 7 animals each and housed in individual cages for 100 days. The pigs were fed with similar diets (13.5 MJ ME and 178 g crude protein/kg) but with different additions of vitamins C+E and taurine. The antioxidative...... vitamins E and C supplied to diets with high energy concentrations (containing lard) can act as pro-oxidants on liver DNA in growing pigs. Taurine decreased the concentration of products from nucleotide oxidation, but in the presence of vitamin E and C, promoted hepatocyte lesions....

  13. Electronic-state distribution of Ar* produced from Ar+(2P3/2)/2e- collisional radiative recombination in an argon flowing afterglow

    The Ar + /2e - collisional radiative recombination has been studied by observing UV and visible emissions of Ar* in an Ar flowing afterglow. In order to clarify recombination mechanism, the Ar + ( 2 P 3/2 ) spin-orbit component was selected by using a filter gas of the Ar + ( 2 P 1/2 ) component. Spectral analysis indicated that 34 Ar*(4p, 4d, 5p, 5d, 6s, 6p, 6d, 4p ' , 4d ' , 5p ' , 5d ' , 6s ' ) states in the 13.08-15.33 eV range are produced. The electronic-state distribution decreased with an increase in the excitation energy of Ar*, which was expressed by a Boltzmann electronic temperature of 0.54 eV. The formation ratios of the 4p: 4d + 5p + 5d + 6s + 6p + 6d: 4p ' : 4d ' + 5p ' + 5d ' + 6s ' states were 43%, 2.8%, 54%, and 0.31%, respectively. The high formation ratio of the 4p ' state having an Ar + ( 2 P 1/2 ) ion core in the Ar + ( 2 P 3/2 )/2e - recombination indicated that such a two-electron process as an electron transfer to an inner 3p orbital followed by excitation of a 3p electron to an outer 4p orbital occurs significantly. The higher formation ratios of 4d + 5p + 5d + 6s + 6p + 6d than those of 4d ' + 5p ' + 5d ' + 6s ' led us to conclude the formation of these upper states dominantly proceeds through one electron transfer to an outer nl orbital of Ar + ( 2 P 3/2 )

    Using data collected with the Belle detector in the energy region of the $\\Upsilon(10860)$ and $\\Upsilon(11020)$ resonances we measure the $e^+e^- \\to h_b(nP)\\pi^+\\pi^-$ $(n=1,2)$ cross sections. Their energy dependences show clear $\\Upsilon(10860)$ and $\\Upsilon(11020)$ peaks with a small or no non-resonant contribution. We study resonant structure of the $\\Upsilon(11020) \\to h_b(nP)\\pi^+\\pi^-$ transitions and find evidence that they proceed entirely via intermediate charged bottomonium-like states $Z_b(10610)$ and/or $Z_b(10650)$ (with current statistics we can not discriminate hypotheses of one or two intermediate states).

    We report on the investigation of dielectron production in tagged quasi-free neutron-proton collisions by using a deuteron beam of kinetic energy 1.25 GeV/u impinging on a liquid hydrogen target. Our measurements with HADES confirm a significant excess of e{sup +}e{sup -} pairs above the π{sup 0} mass in the exclusive channel dp → npe{sup +}e{sup -}(p{sub spect}) as compared to the exclusive channel ppe{sup +}e{sup -} measured in proton-proton collisions at the same energy. That excess points to different bremsstrahlung production mechanisms. Two models were evaluated for the role of the charged pion exchange between nucleons and double-Δ excitation combined with intermediate ρ-meson production. Differential cross sections as a function of the e{sup +}e{sup -} invariant mass and of the angles of the virtual photon, proton and electrons provide valuable constraints and encourage further investigations on both experimental and theoretical sides.

    eHealth provides an important mechanism to connect medically underserved populations with health information, but little is known about gaps in eHealth literacy research in underserved adult populations within the U.S. Between June and July 2013, three systematic literature reviews of five databases were conducted and a subsequent hand search was completed. Identified literature was screened and studies meeting exclusion and inclusion criteria were synthesized and analyzed for common themes. Of the 221 articles critically appraised, 15 met these criteria. Thirty-five of these studies were excluded due to international origin. Of the articles meeting the inclusion criteria, underserved populations assessed included immigrant women, the elderly, low-income, the un- and underemployed, and African-American and Hispanic populations. eHealth literacy assessments utilized included one or two item screeners, the eHEALS scale, health information competence and cognitive task analysis. Factors examined in relation to eHealth literacy included age, experience, overall health literacy, education, income and culture. The majority did not assess the impact of locality and those that did were predominately urban. These data suggest that there is a gap in the literature regarding eHealth literacy knowledge for underserved populations, and specifically those in rural locations, within the U.S.

    The induced modifications in the optical properties of CR-39 and Makrofol-E polymer-based solid state nuclear track detectors were investigated after thermal annealing at a temperature of 200 .deg. C for different durations. The optical properties were studied using an UV-visible spectrophotometer. From the UV-visible spectra, the direct and the indirect optical band gaps, Urbach's energies, and the number of carbon atoms in a cluster were determined. The absorbance of CR-39 plastic detector was found to decrease with increasing annealing time while the absorbance of Makrofol-E decreased with increasing annealing time. The width of the tail of localized states in the band gap ΔE was evaluated with the Urbach method. The optical energy band gaps were obtained from the direct and the indirect allowed transitions in K-space. Both of the direct and the indirect band gaps of the annealed CR-39 detector decrease with increasing annealing time while in Makrofol-E, they decreased after an annealing time of 15 minute and then showed no remarkable changes for a prolonged annealing times. Urbach's energy decreased significantly for both CR-39 and Makrofol-E with increasing annealing time. The number of carbon atoms in a cluster increased in the CR-39 detector with increasing annealing time while it decreased with increasing annealing time for Makrofol-E. We may conclude that the CR-39 detector undergoes greater modifications than the Makrofol-E detector upon thermal annealing at 200 .deg. C. In conclusion, the induced modifications in the optical properties of CR-39 and Makrofol-E are correlated with the temperature and the duration of annealing.

    Recently the Convergent Close-Coupling calculations, (CCC), of Fursa and Bray have been very successful predicting the behavior of the electron impact coherence parameters (EICP) for electron impact excitation of helium. In the present experimental study the linear Stokes parameters P 1 and P 2 have been measured for He(3 1 P) excitation using the polarization correlation technique. Data will be presented for electron impact energies of 40eV and 50eV. At present no other experimental data is available at 40eV. At 50eV angular correlation data measured using the VUV 3 1 P-1 1 S photons are available only out to a maximum electron scattering angle of 85 degrees. Due to the disadvantageous differential cross section and 40:1 branching ratio in favor of the VUV decay, the uncertainties in the present data are large. However, at selected electron scattering angles they are sufficient to distinguish the lack of convergence of the CCC predictions for the 69 state calculations (CCC69) in comparison with the 75 state model (CCC75). In particular at 50 eV incident electron energy and 120 degrees scattering angle the charge cloud alignment angles predicted by the two calculations differ by 90 degrees

    To describe patterns of experimentation with electronic cigarettes as a smoking cessation aid, their self-reported impact on smoking cessation and to identify factors associated with self-reported successful quit attempts within the European Union (EU). A cross-sectional study. 28 European Union member states. We analysed data from wave 82.4 of the Special Eurobarometer survey, collected in December 2014 from all 28 EU member states. The total sample size was n=27 801 individuals aged ≥15 years; however, our analyses were conducted in different subgroups with sample sizes ranging from n=470 to n=9363. Data on e-cigarette experimentation and its self-reported impact on smoking cessation were collected. Logistic regression models were used to assess factors associated with experimentation of e-cigarettes as cessation aids and with successful quitting. Logistic regression was also used to assess changes in the use of e-cigarettes as cessation aids between 2012 (using data from wave 77.1 of the Eurobarometer) and 2014 in each member state. E-cigarettes were often experimented with as a cessation aid, especially among younger smokers (OR=5.29) and those who reported financial difficulties (OR=1.33). In total, 10.6% of those who had ever attempted to quit smoking and 27.4% of those who did so using a cessation aid had experimented with e-cigarettes as a cessation aid. Among those who had used e-cigarettes as a cessation aid, those with higher education were more likely to have been successful in quitting (OR=2.23). There was great variation in trends of use of e-cigarette as a cessation aid between member states. Experimentation with e-cigarettes as a potential cessation aid at a population level has increased throughout the EU in recent years, and certain population groups are more likely to experiment with them as cessation aids. Research on the potential population impact of these trends is imperatively needed. Published by the BMJ Publishing Group Limited. For

    The purpose of this work is to define the state of the art about the problem of the indicators and their capability in reading and foreseeing the urban complexity. Therefore, the theoretical elaborations and the suggestions developed in the report try to convert the different contributions in the Italian and international literature in a frame-work, focusing on those arguments which assume a key role in the study of the urban areas: (a) the problematic definition of the administrative, physics and functional boarders of the cities; (b) the selection of the indicators that describe the urban areas; (c) the description and quality of life and of environment quality in the cities; (d) the sustainability in urban areas. [Italian] Il lavoro si propone di delineare lo stato dell'arte sul problema degli indicatori e sulla loro capacita' di leggere e prevedere la complessita' urbana. Le elaborazioni teoriche e i suggerimenti metodologici sviluppati nel rapporto tentano dunque di tradurre in protocolli di lavoro i diversi contributi prodotti negli ultimi anni nella letteratura italiana e internazionale concentrando in particolare l'attenzione su quei temi che all'interno dello studio dei sistemi urbani assumono un ruolo chiave: (a) la problematica definizione dei confini amministrativi, fisici e funzionali delle citta'; (b) la selezione degli indicatori che descrivono con piu' efficacia il sistema urbano; (c) le dimensioni e la misura della qualita' della vita e dell'ambiente nelle citta'; (d) la sostenibilita' all'interno dei sistemi urbani.

    Cloud computing is a new paradigm shift in information technology. Most of the studies in the cloud are business related while the studies in cloud based e-learning are few. The field is still in its infancy and researchers have used several adoption theories to discover the dimensions of this field. The purpose of this paper is to review and integrate the literature to understand the current situation of the cloud based e-learning adoption. A total of 312 articles were extracted from Science direct, emerald, and IEEE. Screening processes were applied to select only the articles that are related to the cloud based e-learning. A total of 231 removed because they are related to business organization. Next, a total of 63 articles were removed because they are technical articles. A total of 18 articles were included in this paper. A frequency analysis was conducted on the paper to identify the most frequent factors, theories, statistical software, respondents, and countries of the studies. The findings showed that usefulness and ease of use are the most frequent factors. TAM is the most prevalent adoption theories in the literature. The mean of the respondents in the reviewed studies is 377 and Malaysia is the most researched countries in terms of cloud based e-learning. Studies of cloud based e-learning are few and more empirical studies are needed.

    Control of protein synthesis in insulin-responsive tissues has been well characterized, but relatively little is known about how this process is regulated in nervous tissues. The retina exhibits a relatively high protein synthesis rate, coinciding with high basal Akt and metabolic activities, with the majority of retinal ATP being derived from aerobic glycolysis. We examined the dependency of retinal protein synthesis on the Akt-mTOR signaling and glycolysis using ex vivo rat retinas. Akt inhibitors significantly reduced retinal protein synthesis but did not affect glycolytic lactate production. Surprisingly, the glycolytic inhibitor 2-deoxyglucose (2-DG) markedly inhibited Akt1 and Akt3 activities, as well as protein synthesis. The effects of 2-DG, and 2-fluorodeoxyglucose (2-FDG) on retinal protein synthesis correlated with inhibition of lactate production and diminished ATP content, with all these effects reversed by provision of d-mannose. 2-DG treatment was not associated with increased AMPK, eEF2, or eIF2α phosphorylation; instead, it caused rapid dephosphorylation of 4E-BP1. 2-DG reduced total mTOR activity by 25%, but surprisingly, it did not reduce mTORC1 activity, as indicated by unaltered raptor-associated mTOR autophosphorylation and ribosomal protein S6 phosphorylation. Dephosphorylation of 4E-BP1 was largely prevented by inhibition of PP1/PP2A phosphatases with okadaic acid and calyculin A, and inhibition of PPM1 phosphatases with cadmium. Thus, inhibition of retinal glycolysis diminished Akt and protein synthesis coinciding with accelerated dephosphorylation of 4E-BP1 independently of mTORC1. These results demonstrate a novel mechanism regulating protein synthesis in the retina involving an mTORC1-independent and phosphatase-dependent regulation of 4E-BP1.

  9. George E. Valley, Jr. Prize Talk: Quantum Frustrated Magnetism and its Expression in the Ground State Selection of Pyrochlore Magnets

    Science.gov (United States)

    Ross, Kate

    In the search for novel quantum states of matter, such as highly entangled Quantum Spin Liquids, ``geometrically frustrated'' magnetic lattices are essential for suppressing conventional magnetic order. In three dimensions, the pyrochlore lattice is the canonical frustrated geometry. Magnetic materials with pyrochlore structures have the potential to realize unusual phases such as ``quantum spin ice'', which is predicted to host emergent magnetic monopoles, electrons, and photons as its fundamental excitations. Even in pyrochlores that form long range ordered phases, this often occurs through unusual routes such as ``order by disorder'', in which the fluctuation spectrum dictates the preferred ordered state. The rare earth-based pyrochlore series R2Ti2O7 provides a fascinating variety of magnetic ground states. I will introduce the general anisotropic interaction Hamiltonian that has been successfully used to describe several materials in this series. Using inelastic neutron scattering, the relevant anisotropic interaction strengths can be extracted quantitatively. I will discuss this approach, and its application to two rare earth pyrochlore materials, Er2Ti2O7 and Yb2Ti<2O7, whose ground state properties have long been enigmatic. From these studies, ErTi2O7 and Yb2Ti2O7 have been suggested to be realizations of "quantum order by disorder" and "quantum spin ice", respectively. This research was supported by NSERC of Canada and the National Science Foundation.

    We recently demonstrated that N2 reduction by nitrogenase involves the obligatory release of one H2 per N2 reduced. These studies focused on the E4(4H) ‘Janus intermediate’, which has accumulated four reducing equivalents as two [Fe-H-Fe] bridging hydrides. E4(4H) is poised to bind and reduce N2 through reductive elimination (re) of the two hydrides as H2, coupled to the binding/reduction of N2. To obtain atomic-level details of the re activation process, we carried out in situ 450 nm photoly...

    A comprehensive theoretical study of atomic characteristics of energy levels and transitions for the core-excited "6S"e","o(n) and "6P"e","o(n) (n=1–5) states of the boron isoelectronic sequence (Z=6–14) are investigated by the Rayleigh–Ritz variation method and multi-configuration interaction wavefunctions. The relativistic corrections and mass polarization effects are included by first-order perturbation theory. The configuration structures of the high-lying sextet series "6S"e","o(n) and "6P"e","o(n) (n=1–5) of the B-like ions are assigned. The transition rates and wavelengths for the electric dipole transitions "6S"e","o(n)—"6P"o","e(n) (n=1–5) of the B-like ions are calculated and compared with currently available theoretical and experimental data. Furthermore, the radiative transition rates and wavelengths for the important dipole transitions are discussed with the increase of nuclear charge number Z. The calculations will provide useful data for identification of spectral lines arising from the solar atmosphere and the experimental study in future work. - Highlights: • Energy and transition data of core-excited sextet states of B-like ions are studied. • Relativistic corrections, mass polarization effects are included in the calculation. • Radiative rates and transition wavelengths are discussed with the increase of Z. • Variation trend of transition rates and wavelengths are present with the n increase. • Some energy levels and transition data are reported for the first time.

  15. Partial deletion of eNOS gene causes hyperinsulinemic state, unbalance of cardiac insulin signaling pathways and coronary dysfunction independently of high fat diet.

    Full Text Available Abnormalities in eNOS gene, possibly interacting with high fat diet (HFD, affect peripheral vascular function and glucose metabolism. The relative role of eNOS gene, HFD and metabolic derangement on coronary function has not been fully elucidated. We test whether eNOS gene deficiency per se or in association with HFD modulates coronary function through mechanisms involving molecular pathways related to insulin signaling. Wild type (WT, eNOS-/- and eNOS+/- mice were studied. WT and eNOS+/- mice were fed with either standard or HF diet for 16 weeks and compared with standard diet fed eNOS-/-. Glucose and insulin tolerance tests were performed during the last week of diet. Coronary resistance (CR was measured at baseline and during infusions of acetylcholine (Ach or sodium-nitroprusside (SNP to evaluate endothelium-dependent or independent vasodilation, in the Langendorff isolated hearts. Cardiac expression of Akt and ERK genes as evaluation of two major insulin-regulated signaling pathways involved in the control of vascular tone were assessed by western blot. HFD-fed mice developed an overt diabetic state. Conversely, chow-fed genetically modified mice (in particular eNOS-/- showed a metabolic pattern characterized by normoglycemia and hyperinsulinemia with a limited degree of insulin resistance. CR was significantly higher in animals with eNOS gene deletions than in WT, independently of diet. Percent decrease in CR, during Ach infusion, was significantly lower in both eNOS-/- and eNOS+/- mice than in WT, independently of diet. SNP reduced CR in all groups except eNOS-/-. The cardiac ERK1-2/Akt ratio, increased in animals with eNOS gene deletions compared with WT, independently of diet. These results suggest that the eNOS genetic deficiency, associated or not with HFD, has a relevant effect on coronary vascular function, possibly mediated by increase in blood insulin levels and unbalance in insulin-dependent signaling in coronary vessels

    Full Text Available Muito aproximativos são os atuais conhecimentos sobre os processos de decisão e as estratégias que sustentaram a ascensão da potência soviética sob a liderança de Stalin, um legado irremovível quase até o fim. Vários documentos de arquivo permanecem fora do alcance dos investigadores, a começar por uma parte essencial das cartas pessoais de Stalin. Contudo, insistir na decision making pode ser um equívoco, pois o problema parece ser mais amplo: ele é resultado da dificuldade de se obter uma síntese interpretativa e um consenso historiográfico em torno das motivações profundas da política e da perspectiva imperial, dos elementos culturais e ideológicos que tinham prioridade nas estratégias de Stalin, das motivações e dos objetivos dessas mesmas estratégias. O presente artigo faz uma reflexão em torno dessa dificuldade.Too much aproximate indeed is the present understanding of the decision-making processes and strategies that gave support to the rise of the Soviet power under the leadership of Stalin, an insurmountable legacy almost to the end. Many archive sources are still out of reach, an essential part of Stalin's personal letters to begin with. However, to insist on decision making may be a mistake, because the problem seems wider: the difficulty of achieving an interpretative synthesis and historiographical consensus about the deep motivations underlying the imperial perspective and policies, the cultural and ideological elements of Stalin's strategies and their own motivations and objectives. This article is a reflection on that difficulty.

    Full Text Available Studies on the antioxidant treatment for thalassemia have reported variable outcomes. However, treatment of thalassemia with a combination of hydrophobic and hydrophilic antioxidants and an iron chelator has not been studied. This study investigated the effects of antioxidant cocktails for the treatment of β-thalassemia/hemoglobin E (HbE, which is the most common form of β-thalassemia in Southeast Asia. Sixty patients were divided into two groups receiving N-acetylcysteine, deferiprone, and either curcuminoids (CUR or vitamin E (Vit-E, and their hematological parameters, iron load, oxidative stress, and blood coagulation potential were evaluated. Patients were classified as responders if they showed the improvements of the markers of iron load and oxidative stress, otherwise as nonresponders. During treatment, the responders in both groups had significantly decreased iron load, oxidative stress, and coagulation potential and significantly increased antioxidant capacity and hemoglobin concentration. The significantly maximum increase (P<0.01 in hemoglobin concentration was 11% at month 4 in CUR group responders and 10% at month 10 in Vit-E group responders. In conclusion, the two antioxidant cocktails can improve anemia, iron overload, oxidative stress, and hypercoagulable state in β-thalassemia/HbE.

    We report full second Born calculations with inclusion of post-collision interactions for excitation of the (2p 2 ) 1 D and (2s2p) 1 P autoionizing states of helium by 200 eV electron impact. The calculations are compared to (e, 2e) measurements of McDonald and Crowe (McDonald D G and Crowe A 1993 J. Phys. B: At. Mol. Opt. Phys. 26 2887-97) and Lower and Weigold (Lower J and Weigold E 1990 J. Phys. B: At. Mol. Opt. Phys. 23 2819-45). It is shown that post-collision interactions or Coulomb interactions in the final state between the scattered particle, the ejected electron and the recoil ion have a strong influence on both the direct ionization and resonance profiles around the binary lobe. The second-order terms in the amplitude of double electron excitation also play an observable role under these kinematic conditions. Reasonable agreement is found between the full-scale calculations and the experimental data. (author). Letter-to-the-editor

  6. A critique of the US Surgeon General's conclusions regarding e-cigarette use among youth and young adults in the United States of America.

    In December 2016, the Surgeon General published a report that concluded e-cigarette use among youth and young adults is becoming a major public health concern in the United States of America. Re-analysis of key data sources on nicotine toxicity and prevalence of youth use of e-cigarettes cited in the Surgeon General report as the basis for its conclusions. Multiple years of nationally representative surveys indicate the majority of e-cigarette use among US youth is either infrequent or experimental, and negligible among never-smoking youth. The majority of the very small proportion of US youth who use e-cigarettes on a regular basis, consume nicotine-free products. The sharpest declines in US youth smoking rates have occurred as e-cigarettes have become increasingly available. Most of the evidence presented in the Surgeon General's discussion of nicotine harm is not applicable to e-cigarette use, because it relies almost exclusively on exposure to nicotine in the cigarette smoke and not to nicotine present in e-cigarette aerosol emissions. Moreover, the referenced literature describes effects in adults, not youth, and in animal models that have little relevance to real-world e-cigarette use by youth. The Surgeon General's report is an excellent reference document for the adverse outcomes due to nicotine in combination with several other toxicants present in tobacco smoke, but fails to address the risks of nicotine decoupled from tobacco smoke constituents. The report exaggerates the toxicity of propylene glycol (PG) and vegetable glycerin (VG) by focusing on experimental conditions that do not reflect use in the real-world and provides little discussion of emerging evidence that e-cigarettes may significantly reduce harm to smokers who have completely switched. The U.S. Surgeon General's claim that e-cigarette use among U.S. youth and young adults is an emerging public health concern does not appear to be supported by the best available evidence on the health risks

    Edwardsiella tarda, a Gram-negative member of the family Enterobacteriaceae, has been implicated in significant losses in aquaculture facilities worldwide. Here, we assessed the intra-specific variability of E. tarda isolates from 4 different fish species in the eastern United States. Repetitive sequence mediated PCR (rep-PCR) using 4 different primer sets (ERIC I & II, ERIC II, BOX, and GTG5) and multi-locus sequence analysis of 16S SSU rDNA, groEl, gyrA, gyrB, pho, pgi, pgm, and rpoA gene fragments identified two distinct genotypes of E. tarda (DNA group I; DNA group II). Isolates that fell into DNA group II demonstrated more similarity to E. ictaluri than DNA group I, which contained the reference E. tarda strain (ATCC #15947). Conventional PCR analysis using published E. tarda-specific primer sets yielded variable results, with several primer sets producing no observable amplification of target DNA from some isolates. Fluorometric determination of G + C content demonstrated 56.4% G + C content for DNA group I, 60.2% for DNA group II, and 58.4% for E. ictaluri. Surprisingly, these isolates were indistinguishable using conventional biochemical techniques, with all isolates demonstrating phenotypic characteristics consistent with E. tarda. Analysis using two commercial test kits identified multiple phenotypes, although no single metabolic characteristic could reliably discriminate between genetic groups. Additionally, anti-microbial susceptibility and fatty acid profiles did not demonstrate remarkable differences between groups. The significant genetic variation (<90% similarity at gyrA, gyrB, pho, phi and pgm; <40% similarity by rep-PCR) between these groups suggests organisms from DNA group II may represent an unrecognized, genetically distinct taxa of Edwardsiella that is phenotypically indistinguishable from E. tarda.

  10. Structural Transition and Antibody Binding of EBOV GP and ZIKV E Proteins from Pre-Fusion to Fusion-Initiation State

    2018-05-01

    Full Text Available Membrane fusion proteins are responsible for viral entry into host cells—a crucial first step in viral infection. These proteins undergo large conformational changes from pre-fusion to fusion-initiation structures, and, despite differences in viral genomes and disease etiology, many fusion proteins are arranged as trimers. Structural information for both pre-fusion and fusion-initiation states is critical for understanding virus neutralization by the host immune system. In the case of Ebola virus glycoprotein (EBOV GP and Zika virus envelope protein (ZIKV E, pre-fusion state structures have been identified experimentally, but only partial structures of fusion-initiation states have been described. While the fusion-initiation structure is in an energetically unfavorable state that is difficult to solve experimentally, the existing structural information combined with computational approaches enabled the modeling of fusion-initiation state structures of both proteins. These structural models provide an improved understanding of four different neutralizing antibodies in the prevention of viral host entry.

    Molecular detection of HEV in pig livers destined for human consumption in Nuevo Leon, Mexico. 87 livers were collected from pigs slaughtered in TIF and 40 livers from butchers. A 212 pb fragment of HEV ORF2 gene was amplified by semi-nested RT-PCR. 19.54% (17) of tif's and 22.5% (9) of butcher's livers were positive for HEV. Sequencing of the amplified products showed a 94%-95% homology with the sequences reported for genotype 3. Our results indicate that HEV is circulating in swine herds in the state, constituting a probable source of contamination of pig meat products.

    To investigate the nature of drug-excipient interactions between indomethacin (IMC) and methacrylate copolymer Eudragit® E (EE) in the amorphous state, and evaluate the effects on formulation and stability of these amorphous systems. Amorphous solid dispersions containing IMC and EE were spray dried with drug loadings from 20% to 90%. PXRD was used to confirm the amorphous nature of the dispersions, and DSC was used to measure glass transition temperatures (T g ). 13 C and 15 N solid-state NMR was utilized to investigate changes in local structure and protonation state, while 1 H T 1 and T 1ρ relaxation measurements were used to probe miscibility and phase behavior of the dispersions. T g values for IMC-EE solid dispersions showed significant positive deviations from predicted values in the drug loading range of 40-90%, indicating a relatively strong drug-excipient interaction. 15 N solid-state NMR exhibited a change in protonation state of the EE basic amine, with two distinct populations for the EE amine at -360.7 ppm (unprotonated) and -344.4 ppm (protonated). Additionally, 1 H relaxation measurements showed phase separation at high drug load, indicating an amorphous ionic complex and free IMC-rich phase. PXRD data showed all ASDs up to 90% drug load remained physically stable after 2 years. 15 N solid-state NMR experiments show a change in protonation state of EE, indicating that an ionic complex indeed forms between IMC and EE in amorphous solid dispersions. Phase behavior was determined to exhibit nanoscale phase separation at high drug load between the amorphous ionic complex and excess free IMC.

    2017-01-01

    A search for narrow resonances decaying to an electron and a muon is performed using an integrated luminosity of 2.7 fb$^{-1}$ of 13 TeV proton-proton collision data recorded with the CMS detector at the LHC. The e$\\mu$ mass spectrum is also investigated for non-resonant contributions from the production of quantum black holes (QBH). With no evidence for physics beyond the standard model in the invariant mass spectrum of selected e$\\mu$ pairs, upper limits are set at 95\\% confidence level on the product of cross section and branching fraction for signals arising in theories with charged lepton flavour violation. In the search for narrow resonances, the resonant production of a $\\tau$ sneutrino in R-parity violating supersymmetry is considered. The $\\tau$ sneutrino is excluded for masses below 1.0 TeV for couplings $\\lambda_{132} = \\lambda_{231} = \\lambda'_{311} = 0.01$ and below 3.3 TeV for $\\lambda_{132} = \\lambda_{231} = \\lambda'_{311} = 0.2$.

    An attempt has been made to explore selectivity requirements for cyclooxygenase-2 (COX-2) versus cyclooxygenase-1 (COX-1) binding of terphenyl methyl sulfones and sulfonamides using electrotopological state (E-state) index and suitable indicator parameters. Multiple linear regression analyses produced statistically acceptable equations: the best relation based on 'all-possible-subsets regression' for COX-1 binding (n=18) showed predicted variance and explained variance of 0.675 and 0.777, respectively, while in case of the best equation for COX-2 binding (n=38), these values rose to 0.842 and 0.874, respectively. For the selectivity relation (n=17), predicted variance and explained variance values were 0.601 and 0.687, respectively. Based on the results of the analyses, three important sites have been suggested: sites A (methylsulfonyl or aminosulfonyl moiety), B (central phenyl ring), and C (terminal phenyl ring containing different substituents). All three sites are important for COX-2 binding while sites B and C are important for COX-1 binding. For COX-2 selectivity, only site C plays an important role. The study shows the utility of E-state index in developing statistically acceptable model having direct physicochemical significance.

  9. Using activity triggered e-diaries to reveal the associations between physical activity and affective states in older adult's daily living.

    Evidence suggests that older adults show positive affects after participating in exercise bouts. However, it is less clear, if and how physical activities in daily living enhance affective states, too. This is dissatisfying, as most of older adults' physical activities are part of their daily living. To answer these questions we used activity-triggered e-diaries to investigate the within-subject effects of physical activity on three dimensions of affective states (valence, energetic arousal, calmness) during everyday life. Older adults (N = 74) between 50 and 70 years took part in the study during three consecutive days. Physical activity in daily living was objectively assessed using accelerometers. Affects were measured 10 min after a study participant surpassed a predefined threshold for activity or inactivity. The participants were prompted by an acoustic signal to assess their momentary affective states on an e-diary. Data were analyzed with hierarchical multilevel analyses. Whenever older individuals were more physically active, they felt more energized (energetic arousal) and agitated (calmness). However, they did not feel better (valence). Interestingly, body mass index (BMI) and valence were associated in a significant cross-level interaction. BMI acts as a moderating variable in the way that lower BMI scores were associated with higher levels of valence scores after being physically active. The innovative ambulatory assessment used here affords an interesting insight to the affective effects of daily activity of older adults. These effects are no simple and no linear ones, i.e. physical activity is not associated with positive affects per se as shown several times in experimental studies with single activity bouts. Rather there is a differentiating association seen as an enhanced feeling of energy and agitation, which is not accompanied by a better feeling. Socio-emotional selectivity theory may support the finding that older individuals are

    The momentum distributions of hadrons produced in e+e - collisions at a center of mass energy of 29 GeV have been measured. The data used in this analysis were collected by the High Resolution Spectrometer (HRS) at the Positron Electron Project (PEP) in the Spring of 1982. The HRS is a general purpose particle detector consisting of a 16.2 kgauss solenoidal magnet, 17 layers of tracking chambers and multiple layers of lead-scintillator shower counters. The data consist of 8,200 hadronic events, corresponding to an integrated luminosity of 19.6 pbarn -1 at E/sub cm/ = 29 GeV. Using the barrel shower counters' time-of-flight (TOF) measurements, charged particles in the momentum range 0.5 - 1.9 GeV/c are separated statistically. Measurements of differential cross sections, d sigma /dp, scaled cross sections, S*(dsigma/dXp), and charged particle fractions are presented and compared with measurements made by the TASSO and the JADE groups

    Considering importance of developing selective estrogen receptor modulators (SERMs), the present paper explores selectivity requirements of tetrahydroisoquinoline derivatives for binding with ER(alpha) versus ER(beta) receptors using E-state index and physicochemical parameters. The best model [n=21, Q(2)=0.512, R(a)(2)=0.613, R=0.819, F=11.6 (df 3,17)] for ER(alpha) binding data obtained from radioligand binding assay showed importance of C(1), C(15) and lipophilicity (logP) while the best model [n=21, Q(2)=0.768, R(a)(2)=0.796, R=0.904, F=40.1 (df 2,18)] for ER(beta) binding data showed importance of C(1) and molar refractivity (MR). While modeling ER(alpha)/ER(beta) selectivity [n=21, Q(2)=0.695, R(a)(2)=0.739, R=0.882, F=19.8 (df 3,17)], C(1), C(15) and molar refractivity were found to be significant contributors. The data obtained from cellular transcription assay were also modeled. In case of ER(alpha), the best equation involving E-state values of C(1) and C(14) and logP explained 62.1% of the variance while the best equation for ER(beta) involving E-state values of C(1) and C(15) and MR explained 64.6% of the variance of the response variable. In case of ER(alpha)/ER(beta) selectivity, the best equation involving E-state values of O(8), C(14) and N(27) showed 48.3% explained variance, which increased to 63.5% on deletion of single outlier. From the analysis it appears that the nitrogen atom of the aminoethoxyphenyl substituent and 6-hydroxy substituent of the tetrahydroisoquinoline nucleus play important roles for ER(alpha)/ER(beta) selectivity in addition to R(1) and R(2) substituents.

    Neuropeptides are vital for cell-cell communication and function in the regulation of the nervous and endocrine systems. They are generated by post-translational modification (PTM) steps resulting in small active peptides generated from prohormone precursors. Phosphorylation is a significant PTM for the bioactivity of neuropeptides. From the known diversity of distinct neuropeptide functions, it is hypothesized that the extent of phosphorylation varies among different neuropeptides. To assess this hypothesis, neuropeptide-containing dense core secretory vesicles from bovine adrenal medullary chromaffin cells were subjected to global phosphopeptidomics analyses by liquid chromatography (LC)-mass spectrometry (MS/MS). Phosphopeptides were identified directly by LC-MS/MS and indirectly by phosphatase treatment followed by LC-MS/MS. The data identified numerous phosphorylated peptides derived from neuropeptide precursors such as chromogranins, secretogranins, proenkephalin and pro-NPY. Phosphosite occupancies were observed at high and low levels among identified peptides and many of the high occupancy phosphopeptides represent prohormone-derived peptides with currently unknown bioactivities. Peptide sequence analyses demonstrated SxE as the most prevalent phosphorylation site motif, corresponding to phosphorylation sites of the Fam20C protein kinase known to be present in the secretory pathway. The range of high to low phosphosite occupancies for neuropeptides demonstrates cellular regulation of neuropeptide phosphorylation. [Figure not available: see fulltext.

    Informal E-waste recycling can pose a risk to human health and the environment which this study endeavours to evaluate. The distribution of a number of heavy metals in soil from an informal recycling site in the largest market for used and new electronics and electrical equipment in West Africa was investigated. The potential bioavailability of heavy metals, extent of contamination, potential risk due to the recycling activities and impact of external factors such as rainfall were also assessed. The concentrations of all the heavy metals tested were higher in the area where burning of the waste occurred than at the control site, suggesting an impact of the recycling activities on the soil. The order of total metal concentrations was Cu > Pb > Zn > Mn > Ni > Sb > Cr > Cd for both the dry and wet seasons. The total concentrations of Cd, Cu, Mn, Ni and Zn were all significantly higher (p  Sb > Zn > Cu > Ni > Pb > Cr. When the risk was assessed using the Potential Ecological Risk Index (PERI), Cu was found to contribute the most to the potential ecological risk and Cd gave rise to the greatest concern due to its high toxic-response factor within the study site. Similarly, utilising the Risk Assessment Code (RAC) suggested that Cd posed the most risk in this site. This research establishes a high level of contamination in the study site and underscores the importance of applying the appropriate chemical speciation in risk assessment.

    Full Text Available The assessment of effects associated with cognitive impairment using electroencephalography (EEG power mapping allows the visualization of frequency-band specific local changes in oscillatory activity. In contrast, measures of coherence and dynamic source synchronization allow for the study of functional and effective connectivity, respectively. Yet, these measures have rarely been assessed in parallel in the context of mild cognitive impairment (MCI and furthermore it has not been examined if they are related to risk factors of Alzheimer’s disease (AD such as amyloid deposition and apolipoprotein ε4 (ApoE allele occurrence. Here, we investigated functional and directed connectivities with Renormalized Partial Directed Coherence (RPDC in 17 healthy controls (HC and 17 participants with MCI. Participants underwent ApoE-genotyping and Pittsburgh compound B positron emission tomography (PiB-PET to assess amyloid deposition. We observed lower spectral source power in MCI in the alpha and beta bands. Coherence was stronger in HC than MCI across different neuronal sources in the delta, theta, alpha, beta and gamma bands. The directed coherence analysis indicated lower information flow between fronto-temporal (including the hippocampus sources and unidirectional connectivity in MCI. In MCI, alpha and beta RPDC showed an inverse correlation to age and gender; global amyloid deposition was inversely correlated to alpha coherence, RPDC and beta and gamma coherence. Furthermore, the ApoE status was negatively correlated to alpha coherence and RPDC, beta RPDC and gamma coherence. A classification analysis of cognitive state revealed the highest accuracy using EEG power, coherence and RPDC as input. For this small but statistically robust (Bayesian power analyses sample, our results suggest that resting EEG related functional and directed connectivities are sensitive to the cognitive state and are linked to ApoE and amyloid burden.

    Full Text Available As taxas de mortalidade por câncer de cólon e reto mostram uma variação regional no Brasil e a heterogeneidade do padrão alimentar nas suas regiões geográficas poderia possivelmente explicar, pelo menos em parte, essas diferenças. Um estudo ecológico foi realizado com o objetivo de identificar possíveis associações entre padrões de consumo alimentar e taxas de mortalidade padronizadas por idade em capitais brasileiras selecionadas. O padrão de consumo alimentar em cada capital foi caracterizado com base no consumo de grupos de alimentos associados a essa neoplasia na literatura. Os dados de consumo de alimentos foram obtidos no ENDEF (Estudo Nacional de Despesas Familiares. A regressão linear múltipla foi utilizada para analisar as correlações entre as taxas de mortalidade e as variáveis alimentares. Essas taxas mostraram uma correlação positiva com o consumo de calorias, cereais, carnes, ovos/leite e legumes/frutas. Quando ajustado por consumo calórico total, carne e legumes/frutas foram as únicas variáveis que mantiveram uma correlação positiva. O modelo multivariado final com essas variáveis foi capaz de explicar 92% da variação das taxas de mortalidade nas capitais selecionadas. Esses resultados sugerem que diferenças no consumo calórico total e no consumo de carne e legumes/frutas poderiam explicar, parcialmente, os diferentes padrões de distribuição da mortalidade por câncer de cólon e reto no Brasil.Mortality rates for colorectal cancer show regional variations in Brazil, and the heterogeneous dietary profile observed in its geographic regions could possibly explain, at least partially, these different patterns. An ecological study was conducted to identify possible associations between dietary consumption profiles and age-standardized mortality rates for colorectal cancer in selected state capitals. The dietary profile in each capital was characterized on the basis of the consumption of groups of foods

    Purpose: Several vendors of diagnostic lead apron used routinely in radiology/fluoroscopy claim to manufacture 0.5 mm lead equivalent shielding. The purpose of this investigation was to address the concern of the weight of lead aprons versus the radiation protection they provide. Methods: Seven diagnostic lead aprons were measured and compared for their radiation transmission and attenuation characteristics. The measurements were performed on a Philips Integris. Two settings were used, normal (76 kVp, 14.3 mA) and high (110 kVp, 12.3 mA) to represent typical patient and large patient thickness. Plastic water was placed on the table to represent patient scatter. A Capintec PM-500 ion chamber was placed at approximate chest height where hospital personnel would stand. An uncovered, i.e. lead-unhindered, ion chamber reading was taken to establish the baseline reading of an unprotected personnel. The ion chamber was then wrapped with 0.5mm 99.9% pure Pb material to establish the measurement reading when a diagnostic lead apron attenuates as adequately as 0.5mm Pb. The lead aprons were measured one at a time with the ion chamber fully covered and enclosed within the aprons. Results: On Normal fluoroscopy setting, the 0.5mm pure Pb showed a transmission of 0.4%. No aprons showed a transmission value as low as 0.5mm Pb. The lowest transmission value measured from the aprons was 2.0%, having a 1.5% higher transmission than pure lead. On High fluoroscopy setting, the lowest apron transmission measurement was at 2.8%, which was comparable to the 0.5mm pure Pb which gave a transmission of 3.0%. Conclusion: At Normal fluoroscopy setting, the 0.5mm Pb provided an attenuation that could not be matched by any apron measured. At High fluoroscopy setting, only one apron exhibited comparable transmission values as 0.5mm pure Pb.

    We report on measurements of the detected signal pulses in a molybdenum-gold Magnetic Penetration Thermometer (MPT) in response to absorption of one or more 3 eV photons. We designed and used this MPT sensor for x-ray microcalorimetry. In this device, the diamagnetic response of a superconducting MoAu bilayer is used to sense temperature changes in response to absorbed photons, and responsivity is enhanced by a Meissner transition in which the magnetic flux penetrating the sensor changes rapidly to minimize free energy in a mixed superconducting normal state. We have previously reported on use of our MPT to study a thermal phonon energy loss to the substrate when absorbing x-rays. We now describe results of extracting heat capacity C and thermal conductance G values from pulse height and decay time of MPT pulses generated by 3 eV photons. The variation in C and G at temperatures near the Meissner transition temperature (set by an internal magnetic bias field) allow us to probe the behavior in superconducting normal mixed state of the condensation energy and the electron cooling power resulting from quasi-particle recombination and phonon emission. The information gained on electron cooling power is also relevant to the operation of other superconducting detectors, such as Microwave Kinetic Inductance Detectors.

The evaluations were carried out by the Education Department in 1997 and 1998. The study was accomplished based on the percentile of the students achievement in the different tests. The results show improvement in mathematics, sciences and composition and a decline only in Portuguese. In spite of this, the results do not reach satisfactory levels, because in approximately 50% of the tests a high number of students reached percentile inferior to the average. This tendency reveals the need of a review on the system itself, an evaluation beyond the student's performance, with views to the identification and solution of their real deficiencies and vulnerability.

    Full Text Available Nas últimas duas décadas, os estudiosos dos movimentos sociais passaram a questionar as fronteiras do seu campo de pesquisa. Alguns defenderam a substituição do conceito de "movimentos sociais" por "sociedade civil", enquanto outros propuseram falar de "política do conflito". Em ambos os casos, argumentou-se que o campo de estudos havia se tornado excessivamente limitado, tanto empírica como teoricamente. O artigo discute essas iniciativas e identifica um problema comum: a falta de atenção dada às numerosas formas de interação entre ativistas de movimentos sociais situados dentro e fora do Estado. Argumentamos que a pesquisa empírica que vem sendo realizada no Brasil ajuda a compreender melhor a relação entre Estado e movimentos sociais. Do ponto de vista teórico, é a literatura recente sobre redes sociais que oferece pistas analíticas sobre como pensar no ativismo a partir de dentro das estruturas do Estado.In the last two decades, social movement scholars have brought the frontiers of the field into question. Some have advocated for the substitution of "social movements" for "civil society", while others have proposed to rename the field as the study of "contentious politics". In both of these cases, the justification is that the field of social movements has become too narrow, empirically as well as theoretically. The article discusses these reformist initiatives and identifies a problem they have in common: the lack of attention to numerous forms of interaction between actors involved with social movements situated both outside and inside the state. We offer a theoretical discussion based on the results of empirical research undertaken in Brazil on this issue, which, we argue, help us better understand the relationship between states and social movements. We also argue that the recent literature on social networks provides analytical clues to think about activism from within state structures.

    pesquisas, resultados já alcançados, e considerações sobre o futuro.Sustainability is an actual theme and very present in all discussion in the tropical agriculture world, including Brazil. This country experienced high taxes of development in agribusiness, increasing exportation trading, producing foods of better quality and raising incoming rates of farmers. However, two mains aspects call the attention in respect to sustainability: excessive soil preparation with monoculture of annual crops and pasture degradation. These situations have brought losses in crop and livestock yields, increased soil degradation and collapse of natural resources. Continuous cropping of monoculture accelerates attacks of insects and diseases, specially the ones related to soil interactions. Technologies such as minimum tillage, crop rotation and crop-livestock integration can alleviate these problems and drive agriculture to sustainability. Minimum tillage has increase to more than 60% of soil tillage usage in Brazil. Adoption of this system in large scale, covering more regions, with different clime and soil, is highly dependent of crops that produce high amounts of residues and straw for better soil coverage. Crop-livestock integrated systems (CLIS have been cultivated with many crops, such as: soybeans, corn, pearl millet, sorghum, cotton, sunflower, etc. and especially perennial tropical grasses asBrachiaria spp, intercropped or not. CLIS can be one important alternative to pasture recuperation and improvement of annual crops. They increase straw to minimum tillage systems, improve soil chemical, physical and biological properties, and better use of equipments, farmers income, and jobs in rural area.

    Science.gov (United States)

    Chase, Anthony Michael

    The Center for Authentic Science Practices in Education (CASPiE) pioneered a course-based research experience approach to teaching chemistry laboratory courses. The method had previously been studied in a variety of institutional settings. Recently, the United States Military Academy at West Point decided to develop CASPiE-style modules for the introductory honors chemistry course. This research setting presents clean experimental-control comparisons and a group of faculty who were completely new to the method. Equipping students with authentic research experiences early in their education is important regardless of the institution. However, cadets at a military academy must make decisions relatively early (the outset of their second year) as to what their career trajectory will be as eventual officers. In the new CASPiE-based experience, cadets are given the opportunity to select from one of three different modules (analytical chemistry, toxicology, and chemical engineering) in which to participate during the course. These three modules represent subsections of an overall Army waste-to-energy research project. Cadets generate unique hypotheses, real data, and research posters towards the advancement of the project. Posters are then presented in a session. that includes an audience of project stakeholders, course instructors, and other academy faculty and staff. Here, I will present my research methods, evaluative procedures, and findings in the affective domain, critical thinking, and laboratory content comprehension.

    This tabular data set represents the average normalized (wet) deposition, in kilograms per square kilometer multiplied by 100, of Nitrate (NO3) for the year 2002 compiled for every MRB_E2RF1 catchment of the Major River Basins (MRBs, Crawford and others, 2006). Estimates of NO3 deposition are based on National Atmospheric Deposition Program (NADP) measurements (B. Larsen, U.S. Geological Survey, written. commun., 2007). De-trending methods applied to the year 2002 are described in Alexander and others, 2001. NADP site selection met the following criteria: stations must have records from 1995 to 2002 and have a minimum of 30 observations. The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental Protection Agency's (USEPA) ERF1_2 and include enhancements to support national and regional-scale surface-water quality modeling (Nolan and others, 2002; Brakebill and others, 2011). Data were compiled for every MRB_E2RF1 catchment for the conterminous United States covering New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2), the Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4), the Lower Mississippi, Arkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado, and the Great basin (MRB6), the Pacific Northwest (MRB7) river basins, and California (MRB8).

  15. Alignment and orientation of the 21P state of helium by electron impact at 29.6 and 51.2 eV

    1980-01-01

    The electron-photon coincidence technique has been used to deduce the lambda and chi parameters for excitation of the 2 1 P state of helium by electron impact at 29.6 and 51.2 eV incident energies and for electron scattering angles in the range 15 to 130 0 . The lambda parameter shows a minimum at small and large scattering angles. When combined with the data of Hollywood et al (J. Phys. B.; 12:819 (1979)) at 81.2 eV, it can be seen that as the incident energy decreases, the depth of the low-angle minimum decreases and its position moves to larger scattering angles. In contrast, the depth of the second minimum increases with decreasing incident electron energy. The experimental values of lambda and chi are compared with values predicted from the first Born approximation, a distorted-wave polarised-orbital approximation, a first-order many-body theory and an R-matrix theory. None of the theoretical values is in agreement with the measured data although the R-matrix calculation gives a reasonable indication of the features of both lambda and chi at 29.6 eV. (author)

    This study aimed to investigate the qualifications and the job market of secretaries to Sergipe, analyzing the history and evolution of the field before the formal preparation and market demands. After identifying the historical setting of the profession in Brazil, we attempted to verify the behavior of the class secretarial about your organization, qualification and market performance. The exploratory and descriptive research supported the case study, addressing the views of students of Executive Secretariat and managers in the market of Sergipe, besides the pioneering members in the constitution of the occupation in the state. The analysis points to the development of the profession, although later in the educational context. The labor market comes in irregular occupation of the vacancies for the Secretariat, a result that can be attributed to the scarcity of training and little effective dialogues of the class with employers.Este trabalho teve como objetivo investigar a qualificação e o mercado de trabalho do secretário no Estado de Sergipe, analisando-se a trajetória e evolução do campo de atuação diante da preparação formal do indivíduo e demandas do mercado. A partir da identificação do cenário histórico da profissão no Brasil, buscou-se verificar o comportamento da classe secretarial sergipana sobre a sua organização, qualificação e atuação no mercado. A pesquisa exploratória e descritiva subsidiou o estudo de caso, abordando a visão de estudantes do curso de Secretariado Executivo da Universidade Federal de Sergipe e gestores no mercado sergipano, além de membros pioneiros na constituição da ocupação no Estado. As análises apontam para o desenvolvimento da profissão, embora tardio, no âmbito educacional.

    1976-01-01

    We present a detailed treatment of the theoretical and experimental aspects of the symmetric (e,2e) reaction in atoms, molecules and solids. Two experimental arrangements are described for measuring angular correlations and separation energy spectra, the one arrangement employing coplanar and the other noncoplanar symmetric kinematics. The latter arrangement is shown to be particularly suitable for extracting structure information. The basic approximation, the factorized distorted-wave off-shell impulse approximation with fully distorted waves, is shown to correctly describe the reaction in some test cases, as does the phase distortion approximation. At energies of the order of 1200 eV the simple eikonal and plane wave approximations adequately describe the valence shell cross sections for light atoms and molecules containing first row elements. Energy independent structure information is obtained on: (a) shapes and magnitudes of the square of the momentum space wave functions for individual electron orbitals; (b) separation energies for individual ion eigenstates; (c) the characteristic orbital of each state; and (d) spectroscopic factors describing the probability that an eigenstate contains the principal configuration of a hole in the characteristic orbital for each eigenstate. Comparison is made with photoelectron spectroscopy and Compton scattering, since they separately yield some of the information obtained by the (e,2e) method. A brief summary is given of other electron-electron coincidence experiments. (author)

    A systematic study on the photophysical properties and excited state intramolecular proton transfer (ESIPT) behavior of 2-hydroxy-5-[(E)-(4-methoxyphenyl)diazenyl]benzoic acid, is reported using steady-state and time-resolved fluorescence spectroscopy in homogeneous solvents as well as in different micro-heterogeneous environments. Depending on the nature of intramolecular hydrogen bond (IHB), the salicylic acid derivative may exist in two different ground state conformers (I and II). Structure I having IHB between the carbonyl oxygen and phenolic hydrogen can undergo ESIPT upon excitation as evidenced by largely Stokes-shifted fluorescence at ∼455 nm; whereas, normal fluorescence in the blue side of the spectrum (∼410 nm) is due to the spontaneous emission from conformer II. The results in homogeneous solvents were compared with those in bio-mimicking environments of β-cyclodextrin (CD) and surfactants. The intensity of the ESIPT fluorescence increases substantially upon encapsulation of the probe into the cyclodextrin as well as micellar nano-cavities. Detailed analysis of the spectroscopic data indicates that the probe forms 1:1 complex with CD in aqueous medium. Binding constant of the probe with the micelles as well as critical micelle concentration was obtained from the variation of fluorescence intensity on increasing concentration of different surfactants in aqueous medium. -- Highlights: • Steady state and time resolved fluorescence study on ESIPT in HMBA. • Dual fluorescence corresponding to the pro- and non-ESIPT structures. • Modulation of ESIPT fluorescence in micro-heterogeneous environments. • 1:1 stoichiometry for interaction with cyclodextrin. • Calculation of binding constant and other physico-chemical properties from fluorescence titration data in surfactants.

    Full Text Available Conflicting opinions are recorded in the literature concerning the suitability of Amazon lands for sustainable agriculture following deforestation. This article has been written to shed light on this question by summarizing climate, landform, soil and vegetation features from the findings of a land resource study of the Brazilian state of Rondônia in south-west Amazonia. The work, which followed the World Soils and Terrain Digital Database (SOTER methodology, was financed by the World Bank. During the course of the survey special emphasis was given to studying soils; 2914 profiles were analyzed and recorded. The study identified a complex pattern of land units with clear differences in climate, landform, soils and native vegetation. Forested areas mosaic with lesser areas of natural savannas. The latter occur on both poorly-drained and well-drained, albeit nutrient deficient sandy soils. The tallest and most vigorous forests or their remnants were seen growing on well-drained soils formed from nutrient-rich parent materials. Many of these soils could, or are being used for productive agriculture. Soils developed on nutrient-poor parent materials support forests that are significantly lower in height, and would require large lime and fertilizer inputs for agriculture. Low forests with high palm populations and minor areas of wet land savannas cover the poorly drained soils. It is evident that forest clearing in the past was indiscriminant; this cannot be condoned. The diversity of land conditions found throughout Rondônia would suggest that many past studies in the Amazon have simply been too broad to identify significant soil differences.Opiniões divergentes são encontradas na literatura com respeito ao uso de terras da Amazônia para agricultura sustentável apos desmatamento.

The concentration index Hirschman-Hefindahl (IHH is used to verify the evolution of the exportation markets concentration as well as the Constant Market Share (CMS model that separates the sources of exportations development into four components: world trade increase, constitution of the exportation schedule, destination of exportations and competitiveness. The behavior and exportations trend of both sectors are analyzed from 1990 to 2002, subdivided in three periods: 1990-1993, 1994-1998 and 1999-2002. By means of the separation of the development sources through CMS model, it is verified that the development of the world trade and competitiveness are responsible for the increase of the Lumber industry exportations in two sub-periods: 1994-1998 and 1999-2002, being also responsible for the exportations increase of the Paper industry only in the first sub-period. In the second sub-period, competitiveness was not enough to accomplish an increase of the Paper industry, what shows a fragility of policies for the opening of new markets and dissemination of products of the State of Paraná in foreign markets.   Normal 0 21 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabela normal"; mso

    Riassunto. L'analisi è stata condotta al fine di valutare l'effetto sia sulla sopravvivenza globale (OS) sia sulla sopravvivenza libera da progressione di malattia (PFS) della chemioterapia di combinazione in prima linea per il carcinoma pancreatico in fase avanzata di malattia. La presente analisi è limitata agli studi randomizzati controllati (RCT) di fase III. Successivamente è stata applicata la European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) agli RCT di fase III analizzati per ricavare uno score relativo all'entità del beneficio clinico ottenuto per ciascun RCT. Sono state calcolate inoltre le differenze in termini di PFS tra i diversi bracci di trattamento rapportandole con i costi dei farmaci necessari per ottenere il beneficio di PFS. La nostra analisi ha valutato 11 RCT di fase III, per un totale di 4572 pazienti. Combinando i costi della terapia con la misura dell'efficacia espressa dalla PFS, è stato ottenuto un costo di 74,12 euro (€) per mese di vita guadagnato in termini di PFS con la combinazione di 5-fluorouracil, leucovorin, irinotecan e oxaliplatino (FOLFIRINOX), 90,14 € per la combinazione di gemcitabina e oxaliplatino (GEMOX) e 4708,7 € per la combinazione di nab-paclitaxel e gemcitabina. Da questo punto di vista riteniamo che l'utilizzo delle "vecche chemioterapie di combinazione" (per es., GEMOX) non dovrebbe essere completamente abbandonato, ma valutato sul singolo paziente, sulla base di diversi fattori (età, ECOG PS, comorbilità, carico di malattia), al fine di ottenere una reale "tailored therapy".

    Co-cultivation of mutant Penicillium oxalicum SAU(E)-3.510 and Pleurotus ostreatus MTCC 1804 was evaluated for the production of xylanase-laccase mixture under solid-state fermentation (SSF) condition. Growth compatibility between mutant P. oxalicum SAU(E)-3.510 and white rot fungi (P. ostreatus MTCC 1804, Trametes hirsuta MTCC 136 and Pycnoporus sp. MTCC 137) was analyzed by growing them on potato dextrose agar plate. Extracellular enzyme activities were determined spectrophotometrically. Under derived conditions, paired culturing of mutant P. oxalicum SAU(E)-3.510 and P. ostreatus MTCC 1804 resulted in 58% and 33% higher levels of xylanase and laccase production, respectively. A combination of sugarcane bagasse and black gram husk in a ratio of 3:1 was found to be the most ideal solid substrate and support for fungal colonization and enzyme production during co-cultivation. Maximum levels of xylanase (8205.31 ± 168.31 IU g(-1)) and laccase (375.53 ± 34.17 IU g(-1)) during SSF were obtained by using 4 g of solid support with 80% of moisture content. Furthermore, expressions of both xylanase and laccase were characterized during mixed culture by zymogram analysis. Improved levels of xylanase and laccase biosynthesis were achieved by co-culturing the mutant P. oxalicum SAU(E)-3.510 and P. ostreatus MTCC 1804. This may be because of efficient substrate utilization as compared to their respective monocultures in the presence of lignin degradation compounds because of synergistic action of xylanase and laccase. Understanding and developing the process of co-cultivation appears productive for the development of mixed enzyme preparation with tremendous potential for biobleaching.

Os termos político - sociais dessa transição, de uma forma clássica de proteção para formatos institucionais ainda não muito definidos é que a nosso ver carecem de uma observação mais apurada e sistemática. Queremos propor neste trabalho, de caráter ensaístico, que a transição referida vem acontecendo no âmbito de um movimento con contornos de um neopuritanismo com a função de regular um processo seletivo e excludente de um novo perfil de trabalhador. Salientamos que este processo se dá nos moldes da transição de trabalhador. Salientamos que este processo se dá nos moldes da transição que ocorreu no movimento de transformação das relações capitalistas no inicio do século XX, quando se acontece a passagem do modelo de produção manufatureira para a forma fabril, em outras palavras, a introdução da produção nos moldes taylorista-fordista

    Full Text Available There is no information about evidence of hepatitis E virus (HEV infection in swines in Central Brazil. In order to assess if HEV circulates in swines of the State of Mato Grosso, Central Brazil, a seroprevalence study was conducted including pigs from 17 farms, corresponding to 13 counties. The animals were randomly chosen among pigs arriving to two slaughterhouses between December 2002 and February 2003. Serum samples were collected and tested for IgG antibodies against HEV (anti-HEV by enzyme immunoassay (EIA. This EIA uses two HEV recombinant proteins as antigens, a mosaic protein (MP-II and a protein containing region 452-617 of the ORF2 of the HEV Burma strain as coating antigens. 211 out of 260 pigs (81.2%; 95CI = 75.7%, 85.6% were anti-HEV reactive. The seropositivity did not vary with gender or age, but ranges from 15% to 100% among the farms. Our results point out that HEV seems to circulate among pigs in Mato Grosso State, suggesting that this virus is spread over the region, as seen in other countries worldwide.A infecção pelo vírus da hepatite E (VHE ainda não foi detectada entre suínos na região central do Brasil.

    This report is based on information gathered in the course of a trip to the United States, in November and December 1958 which consisted chiefly of visits to the main biological and medical research laboratories and discussions with the heads of these establishments. A description is given of the general organisation of the Atomic Energy Commission's Division of Biology and Medicine, and of the distribution of responsibility for radiation protection work and for biological, medical and agricultural research amongst the various Services attached to it; this is followed by a more detailed account of the activities carried on in this field at the great national laboratories. Finally, the systems of collaboration set up with external research organisations in the form of research contracts are examined, together with the substantial help provided by the A.E.C. for biological, medical and agricultural research in general, owing to a systematic policy of subsidising the distribution of radioisotopes for this purpose.

    We report measurement of product state distributions for the rotationally and/or vibrationally excited HX formed in collisions of translationally hot H atoms with HX (X = Cl, Br, and I) at 1.6 eV collision energy. The product state distributions are probed after only one collision of the fast H atom, using coherent anti-Stokes Raman scattering spectroscopy. Whether proceeding by inelastic collisions or reactive exchange, the transfer of translational energy to vibrational and rotational energy is quite inefficient in H+HX collisions at 1.6 eV. For all three hydrogen halides only 2--3% of the initial translational energy appears as HX vibration. For H+HCl only 6% of the initial energy is converted to HCl rotational energy, while for H+HBr and H+HI, this percentage is twice as large, 11--12%, but still small. The indistinguishability of the two H atoms involved makes it impossible to distinguish reactive exchange from inelastic energy transfer in these H+HX collisions. However, the difference in rotational energy partitioning for H+HBr and H+HI as compared with H+HCl, suggests that reactive exchange is dominant in the former and inelastic energy transfer dominates in the latter. The total cross sections for the combined energy transfer/reactive exchange do not change much with the identity of X, being 13 +- 3, 11 +- 2, and 11 +- 2 A 2 , for H+HCl, H+HBr, and H+HI, respectively

    After considering that N 2 obtained from flue gas with the use of the separated CO 2 rich current is the best economical alternative for the replacement of natural gas injection for some Reconcavo Basin oil fields and the huge potential for miscible flooding projects at that area, PETROBRAS/E and P-Ba decided to perform an integrated analysis of their N 2 and CO 2 projects in order to maximize their results. Candeias and Agua Grande fields are the main targets for natural gas substitution. They will consume 400 and 700 Mm 3 /d and will make available 80 and 140 ton/d of CO 2 , respectively, to be used in miscible flooding projects. These projects will increase the natural gas availability for the fast growing market at Bahia state and produce up to 220 m 3 /d of oil with an increase of 6.7 % in the ultimate recovery of Santiago/Block 3 reservoir at Miranga field. The integrated analysis took in account all the facilities, works, and services necessary to implement the projects including: separation of the currents from the flue gas, pipelines, compressors, N 2 separation from the produced gas, and workovers. Besides, it was also considered the impact of these projects on the operational costs of those fields and the possibility of using the contaminated gas for future WAG projects. This paper presents the premises, the alternatives and the economical results obtained from the integrated analysis of the PETROBRAS/E and P-Bahia State, Brazil, N 2 and CO 2 projects. (author)

Objetiva também apresentar as relações da imigração com a formação dos serviços sanitários estaduais e com a elaboração do modelo tecno-assistencial por eles adotado a partir da década de 1890. Num momento em que a febre amarela era a mais freqüente e letal das epidemias que afetavam o estado, matando principalmente os estrangeiros, a defesa do fluxo migratório foi um dos fios condutores das ações em saúde pública. A combinação entre os interesses da cafeicultura, a expansão ferroviária, imigração e febre amarela definiu os rumos da ação sanitária promovida pelas oligarquias no poder nesse período em São Paulo. A organização autoritária do Estado brasileiro não dava espaço à implantação de ações individuais de assistência à saúde. Sempre reivindicada pela população urbana e rural, somente com o desenvolvimento da medicina previdenciária no país, na década de 1930, difundiram-se as ações de assistência individual à saúde.The article discusses sanitation issues as aspects of the process of foreign immigration into São Paulo state during the first decade after the Proclamation of the Republic.

Inicialmente, desenvolve-se uma reflexão sobre o conceito de participação em suas diversas dimensões e possibilidades. A segunda parte enfoca os públicos participativos no Brasil privilegiando a institucionalização das relações entre o Estado e a sociedade civil. A terceira parte se centra nas possibilidades de construção de espaços de inovação institucional. As experiências explicitam a existência/inexistência de um potencial de ruptura em torno da distância quase sempre presente entre o poder centralizado e as realidades sociais mutantes e heterogêneas. Isto põe em evidência os limites dos mecanismos existentes formais, verticais, corporativos e clientelistas, construídos para permitir/impedir a participação dos cidadãos nos assuntos públicos. O principal desafio está em fortalecer espaços deliberativos e a modernização dos instrumentos de gestão e de articulação. Para tanto, requer-se uma engenharia sócio-institucional pautada pela premissa da superação das barreiras socioinstitucionais existentes e o necessário fortalecimento na sociedade de políticas pautadas pela inclusão da noção de interesse geral. Isto se potencializa na medida em que o tema da cidadania é assumido como um ponto nodal para a institucionalização da participação dos cidadãos em processos decisórios de interesse público no contexto das políticas educacionais, assim como aquelas que com ela se relacionam e são interdependentes.The article approaches the theme of participation as a continuous process of democratization of educational administration.

    The possibility to realize a nuclear clock based on the optical magnetic dipole transition from the ground state to the low-energy isomeric state in the {sup 229}Th nucleus has motivated experiments and proposals toward highly accurate clocks with trapped ions and highly stable optical frequency standards with Th-doped solids. These systems hold great promise to open a field of research in the borderland between atomic and nuclear physics, which will enable highly sensitive tests of postulates from fundamental physics and also will allow us to coherently excite and control nuclear states, opening a wonderful and intriguing new field in physics. A major experimental obstacle that has to be overcome before any precision spectroscopy can be performed with this system is however the insufficient knowledge on the exact transition energy. The best experimental result so far is an indirect determination from {gamma}-spectroscopy with a relative uncertainty of about 6%. To facilitate the search for the nuclear transition within a wide uncertainty range around 8 eV, we investigate two-photon excitation in the dense electronic level structure of Th{sup +}, which enables the nuclear excitation via a resonantly enhanced inverse electronic bridge process. Experiments on one- and two-photon laser excitation of buffer gas cooled {sup 232}Th{sup +} ions in a radio-frequency ion trap are reported in this thesis. The strongest resonance line at 402 nm from the (6d{sup 2}7s)J=3/2 ground state to the (6d7s7p)J=5/2 state is driven as the first excitation step. Using nanosecond laser pulses in the 250-nm wavelength range for the second step of a two-photon excitation, we have observed seven previously unknown levels in the unexplored region of the electronic level structure around 8 eV. This investigation shows that the Th{sup +} ion seems to be well suited for the search of the isomer transition because both, theory and experimental results, agree on the density of strong transitions

    Full Text Available Information on the resistance profiles of normal intestinal flora of extensively reared chickens that hardly receive antibiotics in the developing countries can serve as important means of understanding the human/animal pathogens drug resistance interactions in the zone. Three hundred and fifty E. coli isolates, comprising 133 from urban and 217 from rural sites in Imo state, Nigeria, were screened for anti-microbial resistance profile against 10 antibiotics using the disc diffusion method. Overall percentage anti-microbial resistance of the isolates against cotrimoxazole, ampicillin, nalidixic acid, chloramphenicol and nitrofurantoin (72–92% were very high. The organisms were highly sensitive to other antibiotics, especially gentamicin and ciprofloxacin. The 59.5% overall mean percentage resistance recorded at the urban area was significantly higher than the 46.8% recorded at the rural area (p<0.05. With the exception of the figures for cotrimoxazole and ampicillin, resistance values obtained against the other antibiotics at the urban sites were statistically higher than those obtained at the rural sites (p<0.05. Zero resistance was recorded against the fluoroquinolones, norfloxacin and ciprofloxacin at all the rural sites except at Enyiogwugwu where a 28.6% resistance was obtained against norfloxacin. Since free-range chickens rarely receive antibiotic medication, it is concluded that the highly resistant E. coli organisms isolated from them may be reflecting consequences of human drug use in the study areas.

    We study the inclusive (e,e'N), (e,e'NN), (e,e'π), (e,e'πN) reactions in nuclei using a Monte Carlo simulation method to treat the multichannel problem of the final state. The input consists of reaction probabilities for the different steps evaluated using microscopical many body methods. We obtain a good agreement with experiment in some channels where there is data and make predictions for other channels which are presently under investigation in several electron laboratories. The comparison of the theoretical results with experiment for several kinematical conditions and diverse channels can serve to learn about different physical processes occurring in the reaction. The potential of this theoretical tool to make prospections for possible experiments, aiming at pinning down certain reaction probabilities, is also emphasized. (orig.)

    Full Text Available Acondicionaram-se sementes de arroz 'IAC 1246' (Oryza sativa L. e milho 'Hmd 7974' (Zea mays L. em embalagens permeáveis ao vapor de água - pano, papel, plástico trançado 5 x 5 e 5 x 6 - e na relativamente impermeável - plástico liso, de 0,25 mm de espessura. Mantiveram-nas em condições não controladas de armazém nas localidades de Campinas e Ubatuba, testando-as quanto à umidade, germinação e vigor a cada trimestre, por 36 meses. As sementes armazenadas em Ubatuba deterioraram-se mais rapidamente, sobretudo quando acondicionadas nas embalagens permeáveis. Em Campinas, as sementes de arroz embaladas em sacos de pano mantiveram germinação acima de 80% até os quinze meses, enquanto aquelas de Ubatuba o fizeram somente até os seis meses. O acondicionamento em saco de plástico liso foi bastante vantajoso, principalmente em Ubatuba, onde, aos 15 meses, a germinação das sementes de milho foi nula quando mantidas nas outras embalagens, e de 97,5% quando no saco plástico liso. As embalagens de pano, papel, plástico trançado 5 x 5 e 5 x 6 foram semelhantes entre si na manutenção da germinação e do vigor das sementes. Os resultados obtidos salientaram a grande dificuldade ou mesmo impossibilidade do armazenamento de sementes em áreas, quentes e úmidas, como Ubatuba, a menos que haja controle da temperatura e umidade relativa do ambiente do armazém, ou mediante secagem das sementes até níveis relativamente baixos de umidade (10-11% ou menos seguida de acondicionamento em embalagem que ofereça resistência à troca de umidade. As embalagens permeáveis ao vapor de água mostraram-se bastante práticas para o armazenamento em regiões de clima mais favorável à manutenção da viabilidade das sementes.Seeds of 'IAC 1246' rice (Oryza sativa L. and 'Hmd 7974' hybrid corn (Zea mays L. were packed in water vapor permeable containers as cloth bag, paper bag 5 x 5 and 5 x 6 woven plastic bag; and in a 0.25 mm thick moisture

    For over ten years now, eurobserv'eR has been collecting data on european Union renewable energy sources to describe the state and thrust of the various sectors in its thematic barometers. The first part of this assessment is an updated and completed summary of the work published in 2011. It provides a complete overview of the ten renewable sectors, supplemented by two summary notes on concentrated solar power and ocean energies. Their performances are compared against the european Commission White Paper and Biomass Action plan targets. The eurobserv'eR consortium members will publish their end-of-year estimates of the renewable energy share of overall final energy consumption for each European Union country from this edition onwards. These figures will thus provide preliminary indication of how the various countries are faring along their renewable energy paths and will ascertain whether their individual trends point to success in achieving their objectives [Dutch] Depuis plus de dix ans, eurobserv'er collecte des donnees sur les sources d'energies renouvelables de l'union europeenne afin de decrire, dans des barometres thematiques, l'etat et la dynamique des filieres.

    The α capture reaction 32 S(α,γ) 36 Ar was studied in the bombarding energy range of E/sub α/ = 4.13 to 5.00 MeV corresponding to the excitation energy range of E/sub x/ = 10.31 to 11.08 MeV in 36 Ar. Seven resonances have been located and their resonance strengths determined. Two of the resonances decay predominantly to the ground state while the other five decay predominantly to the first excited state of 36 Ar. Angular distribution measurements of the predominant decay gamma ray have been performed and the spin and parity of all the resonances assigned. The isospin of two of the resonances have been assigned as T = 0 while T = 1 has been assigned for three others. Evidence has been obtained for the operation of the isospin selection rule for the dipole (E1 and M1) and quadrupole (E2) gamma decay

    To investigate the validity and reliability of modified Mini Mental State Examination (MMSE-E) for illiterate patients in a Turkish population with Alzheimer's disease (AD). A total of 107 illiterate patients with Alzheimer's Disease (women: 65, men: 42) and 68 illiterate healthy volunteer subjects (women: 36, men: 32) were included in the study. MMSE-I and Geriatrics Depression Scale were performed on all subjects, Alzheimer patients were also administered Basic Activities of Daily Living (B- ADL). Clinical Dementia Rating (CDR) was used to determine the severity of disease, while a receiver operating characteristic (ROC) analysis was performed to analyze the cut-off scores of MMSE-I, and the positive/negative predictive values that were calculated for the optimal cut-off scores. Internal consistency was measured using Cronbach's coefficient . Additionally, correlations between total MMSE-I score and the CDR, B-ADL, and GDS scores were examined. The MMSE-I scores significantly and inversely correlated with CDR (-0.82, p=0.000) and B-ADL scores (-0.051, p=0.000). The optimal cut-off points of MMSE-I were 23/24, which yielded a sensitivity of 99.0% - %100.0, a specificity of 98.5% - 97.0%, and an AUC of 1.0/1.0, respectively. Reliability of the MMSE-I was high α = 0.70). The total MMSE-I score was able to differentiate the AD group from the control group.

    Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics. The rates of overall cancer mortality and major types were corrected by proportionally redistributing 50% of ill-defined causes of death and standardizing them by age according to the standard world population. Trend curves for Brazil and its major regions were calculated for state capitals and other municipalities according to sex, and were evaluated by means of simple linear regression. RESULTS: Among men, ascending mortality rates were observed for lung, prostate and colorectal cancer; declining rates for stomach cancer; and stable rates for esophagus cancer. Among women, mortality from breast, lung and colorectal cancer increased, and the rates for cervical and stomach cancer declined. Mortality evolution varied across the regions of Brazil, with distinct patterns between state capitals and other municipalities. CONCLUSIONS: The correction of mortality rates based on redistribution of ill-defined causes of death increased the magnitude of the overall cancer mortality in Brazil by approximately 10% in 1980 and 5% in 2006. In the inland municipalities no decrease or stability was identified, differently from what was observed in the state capitals. Limited scope of prevention actions and lower access to services of cancer diagnosis and treatment for the population living away from large urban centers may partly explain these differences.

    This thesis deals with the problem of safe navigation for autonomous vehicles in dynamic environments. Motion safety is defined by means of Inevitable Collision States (ICS). An ICS is a state for which, no matter what the future trajectory of the vehicle is, a collision eventually occurs. For obvious safety reasons, an autonomous system should never ever find itself in one of such states. To accomplish this objective the problem is addressed in two parts. The first part focuses on determinin...

Com o propósito de superar pontos de estrangulamentos que limitavam a expansão do setor produtivo, o governo estadual investiu nas áreas de educação, transporte, energia, sistema de crédito e agricultura e os resultados alcançados nesse decênio se refletiram na expansão no número de salas de aulas, ginásios de esporte, qualificação de professores, tempo de estudo de alunos, implantação e reformas de rodovias, expansão da oferta de energia, criação de sistema de crédito estadual, aumento da oferta agrícola, integração de produtores rurais, entre outros. Os dados coletados revelam que ao fim desse período, Santa Catarina pode contar com melhores condições infraestruturais para participar do movimento de crescimento da economia nacional. Em consequência disso, os resultados da pesquisa de maneira geral apontam que os ideais defendidos pela corrente desenvolvimentista, ou seja, aquela que entende que o Estado é o agente responsável pela garantia da criação das condições favoráveis à expansão das atividades produtivas e, consequentemente, pelo avanço em relação aos indicadores de desenvolvimento, ficam fortalecidos.  This paper describe the result of a descriptive and exploratory study that refers to an predominantly qualitative research about the experiences of economic planning carried out by the government of Santa Catarina (Brazil during the period between 1961 and 1970 and which became known as PLAMEG I and PLAMEG II.  In order to overcome the limits to the expansion of the productive sector, the government has

    The effects of Se(IV) on the structure and function of recombinant human arsenic (+3 oxidation state) methyltransferase (AS3MT) purified from the cytoplasm of Escherichia coli were studied. The coding region of human AS3MT complementary DNA was amplified from total RNA extracted from HepG2 cell by reverse transcription PCR. Soluble and active human AS3MT was expressed in the E. coli with a Trx fusion tag under a lower induction temperature of 25 degrees C. Spectra (UV-vis, circular dichroism, and fluorescence) were first used to probe the interaction of Se(IV) and recombinant human AS3MT and the structure-function relationship of the enzyme. The recombinant human AS3MT had a secondary structure of 29.0% alpha-helix, 23.9% beta-pleated sheet, 17.9% beta-turn, and 29.2% random coil. When Se(IV) was added, the content of the alpha-helix did not change, but that of the beta-pleated sheet increased remarkably in the conformation of recombinant human AS3MT. Se(IV) inhibited the enzymatic methylation of inorganic As(III) in a concentration-dependent manner. The IC(50) value for Se(IV) was 2.38 muM. Double-reciprocal (1/V vs. 1/[inorganic As(III)]) plots showed Se(IV) to be a noncompetitive inhibitor of the methylation of inorganic As(III) by recombinant human AS3MT with a K (i) value of 2.61 muM. We hypothesized that Se(IV) interacts with the sulfhydryl group of cysteine(s) in the structural residues rather than the cysteines of the active site (Cys156 and Cys206). When Se(IV) was combined with cysteine(s) in the structural residues, the conformation of recombinant human AS3MT changed and the enzymatic activity decreased. Considering the quenching of tryptophan fluorescence, Cys72 and/or Cys226 are deduced to be primary targets for Se(IV).

    Full Text Available Este artigo analisa o crescimento pró-pobre nas 27 unidades federativas do Brasil entre 1995 e 2007. Inicialmente, examina-se a literatura recente sobre o tema e apresentam-se três indicadores para mensurar a relação entre crescimento, desigualdade e pobreza. Em seguida, calcula-se, através de dados de painel, a elasticidade renda-pobreza para o Brasil e suas 27 UFs. Finalmente, estimam-se curvas de incidência do crescimento (GIC e taxas de crescimento pró-pobre (RPPG para cada estado nos períodos 1995-2007, 1995-2001 e 2001-2007. Os resultados demonstram que a pobreza caiu rapidamente no Brasil desde 2001, mas ainda existe grande discrepância entre estados e regiões. Ademais, demonstra-se a diferença entre extensão e profundidade da pobreza.This article analyzes the pro-poor growth in the 27 Brazilian states between 1995 and 2007. Initially, it examines the recent literature about the subject and presents three indicators to quantify the relationship among growth, inequality and poverty. Following, it calculates, through panel data analysis, the growth elasticity of poverty in Brazil and across its states. Finally, it estimates growth incidence curves (GIC and rates of pro-poor growth (RPPG for three periods: 1995-2007, 1995-2001 and 2001-2007. The results show that poverty has been rapidly diminishing in Brazil since 2001, but there is still a huge discrepancy among some states and regions. Moreover, there comes up a clear difference between the headcount index and the "deepness" of poverty.

    Full Text Available O texto apresenta mapeamento e caracterização de parcerias entre escolas estaduais do estado de São Paulo e empresas, nos anos de 1996 e 1997. Após uma descrição de iniciativas governamentais de estímulo à parceria, no âmbito estadual, são apresentados depoimentos de diretores de escola e de representantes das empresas parceiras, que possibilitam ilustrar a abrangência, a natureza e as tendências das ações em desenvolvimento. Evidencia-se que ao crescente empenho governamental de incentivo às parcerias, expresso nos últimos anos, não corresponde uma ampliação significativa dessa prática no estado.This paper presents a survey and characterization of partnerships between state schools in São Paulo and enterprises, in 1996 and 1997. After showing Government initiatives to increase this partnership at state level, are presented statements of school principals and representatives of partner enterprises that show the wideness, nature and prospects of actions in development. It is evident that at the same time we see an increasing governmental involvement to develop partnerships, in last years, there is not a correspondent raise of this practice at state level.

    E-cigarette use occurs with tobacco product use in youth. Using the 2014 National Youth Tobacco Survey (NYTS), we examined past 30-day frequency of cigarette, cigar, smokeless, and e-cigarette use in the context of past 30-day and ever tobacco product use in US middle and high school students (N = 22 007). Frequency of product-specific use was examined by exclusive versus concurrent use with another product in the past 30 days (poly-use). In 2014, the majority (83%) of US middle and high school students had not used tobacco or e-cigarettes in the past 30 days. In the 9.3% of youth reporting any past 30-day e-cigarette use, 63% also reported using a tobacco product; among the 3.3% past 30-day exclusive e-cigarette users, about two-thirds (2.1%) had ever used combustible or non-combustible tobacco products and one-third (1.2%) had not. Few never tobacco users had used e-cigarettes on 10 or more days in the past month (absolute percent e-cigarette and cigar users, prevalence decreased with increasing frequency of use. The majority of past 30-day cigarette, cigar, smokeless, and e-cigarette users reported poly-use. Prevalence estimates for a single product mask the complex patterns of frequency, temporality, and poly-use in youth. Two-thirds of past 30-day exclusive e-cigarette users have ever used tobacco. Poly-use is the dominant pattern of tobacco and e-cigarette use among US middle and high school students. Our study highlights the complexity of tobacco use patterns in US middle and high school students. Future studies addressing the full public health impact of movement into or out of combustible tobacco use will require longitudinal data with appropriate measures of tobacco and e-cigarette product-specific use (eg, frequency and intensity), as well as adequate sample size and a sufficient number of waves to determine how use of individual products, like e-cigarettes, impact progression into or out of more stable patterns of tobacco and e-cigarette use. © The

    Full Text Available Resumo: Cada vez mais o poder público limita direitos e aumenta a repressão, sem corrigir as falhas que levam ao conflito. Isso indica o uso do direito como garantidor de ordem, não de liberdade. O intento deste artigo é mostrar, discutindo as noções de estado e constituição, o conflito entre liberdade e ordem e como o direito serve para proteger a primeira. Assim, relaciona-se a legalidade no estado contemporâneo com a limitação do poder. Faz-se, então, a relação com a ideia de nação e a prevalência da vontade do estado. Após, trabalha-se o estado de exceção e como a ordem e a coerção estatal são postas acima dos direitos e garantias constitucionais. A prevalência da ordem sobre a proteção constitucional pode ser vista nas manifestações de junho de 2013; nos rolezinhos e na situação do presídio de Pedrinhas, exemplos da lógica do estado de exceção incorporada à vida política brasileira, o que responde à discussão teórica que os antecede. Ademais, o estado brasileiro aumenta seu poder de repressão com estratégias jurídicas que diminuem seus limites ou seu controle. O texto defende a necessidade de retomar as lógicas da legalidade e do constitucionalismo para combater a naturalização do estado de exceção.   Abstract: Nowadays is getting usual for the government to limit rights and expand its capacity of repression without correcting the flaws that cause conflicts. This indicates the use of the law as a way to grant order, not liberty. The aim of this article is to show, discussing the ideas of state and constitution, the tension between liberty and order and how the law should work to protect the former. Thus, the contemporaneous state is related to legality, understood as a mean to limit the state power. Then, the concept of state of exception is presented and is shown as the state order and coercion overlap constitutional rights. This overlapping can be seen in the “June 2013” protests; in

Este estudo foi realizado num Latossolo Vermelho-Amarelo da região de Primavera, com objetivo de avaliar a biomassa e a atividade microbiana de solos sob vegetação nativa e sistemas agrícolas anuais e perenes. As amostras de solo foram coletadas em duas profundidades (0-5 e 5-20 cm, no início da estação chuvosa, em áreas sob cultivo de videira (Vitis vinifera, entrelinha e linha, cultivos anuais (soja e em uma área de vegetação nativa de Cerradão. Foram avaliados o carbono da biomassa microbiana (CBM, carbono prontamente mineralizável e as atividades das enzimas beta-glucosidase, fosfatase ácida e arilsulfatase. Nas duas profundidades avaliadas, os sistemas de uso do solo com culturas perenes e anuais apresentaram reduções médias de 70 % no CBM, em relação à área sob vegetação nativa. O manejo diferenciado na entrelinha do parreiral e a utilização do capim-pé-de-galinha (Eleusine indica, como cobertura viva, proporcionaram aumentos no C mineralizável e na atividade das enzimas beta-glucosidase e arilsulfatase nas duas profundidades. Os níveis médios de P no solo sob Cerradão resultaram em valores de atividade da fosfatase ácida inferiores aos dos observados em outros locais do Cerrado. Mesmo assim, na profundidade de 0-5 cm, a atividade da fosfatase ácida no Cerradão foi superior à da entrelinha do parreiral (VE e à da área com culturas anuais, demonstrando a sua importância na mineralização do fósforo orgânico em áreas sob vegetação nativa.

MÉTODO: Este é um estudo descritivo e transversal, baseado em dados secundários. A partir de uma lista de indicadores de bem-estar empregada nos Estados Unidos, equivalentes brasileiros foram pesquisados nos sites de instituições públicas de saúde ou de planejamento. Também foram utilizados dados de pesquisas nacionais e, se necessário, foram feitas reanálises de bases de dados. RESULTADOS: Dos 31 indicadores que compõem a lista norte-americana, somente para três não foi encontrado um equivalente brasileiro: comprometimento de memória, atividade social e crimes violentos. Nos Estados Unidos, o número de idosos foi maior e a escolaridade desse grupo foi mais alta. Os dois países foram semelhantes em termos de condição de saúde e expectativa de vida aos 65 anos. Maiores taxas de óbito por doença cerebrovascular e diabetes foram registradas no Brasil e por neoplasias malignas nos Estados Unidos. A morbidade auto-referida por artrite e por depressão foi mais freqüente nos Estados Unidos, assim como as incapacidades. A autopercepção de bom estado de saúde foi superior no Brasil, ao passo que os indicadores de hábitos de vida e os fatores de risco revelaram uma melhor situação nos Estados Unidos. CONCLUSÕES: Se o poder discriminatório dos indicadores utilizados for de fato adequado, as condições de saúde dos idosos no ano de 2000 eram próximas nos dois países.OBJECTIVE: To identify indicators used in evaluating the population 65 years of age and older in Brazil that are comparable to those used in the United States, and to compare the situation of this age group in the two countries.

    Full Text Available Apesar do amplo processo de desestatização ocorrido internacionalmente nas décadas de 1980 e 1990, as empresas estatais permanecem desempenhando significativo papel na implementação de políticas públicas e na oferta de bens e serviços à sociedade. Entretanto, sua natureza institucional e estrutura de controle tornam complexas as definições de seus objetivos operacionais, a avaliação de seu desempenho, e a própria gestão executiva das empresas, já que sua atuação está sujeita tanto às necessidades de seu controlador imediato, o governo; quanto aos interesses difusos de seu controlador indireto, a sociedade, além das expectativas de retorno financeiro dos sócios privados nas sociedades de economia mista. No momento que a Organização para a Cooperação e Desenvolvimento Econômico (OCDE propõe diretrizes para a governança corporativa de empresas estatais, que estabelecem referências para o relacionamento entre Estado, conselheiros, gestores, investidores e outras partes interessadas, este artigo avalia essas diretrizes quanto à adequação das propostas ao contexto das estatais brasileiras e sua possibilidade de implementação.Despite the extensive process of privatization that has been undertaken in many countries during the 80s and 90s, the state-owned enterprises (SOEs remain performing an important role in the implementation of public policies and in the offering of goods and services to the society.

    Nuclear temperatures extracted from excited state populations were measured as a function of linear momentum transfer (LMT) for 40 Ar+ 197 Au reactions at 25MeV/nucleon. The emission temperatures increased slightly with increasing linear momentum transfer or decreasing impact parameter. Taking into account the corrections of detection efficiency and sequential feeding from higher-lying states, a temperature of T∼4MeV was deduced for central collisions. For peripheral collisions the extracted temperatures increased with the energy of the particles. (orig.)

    Full Text Available A mudança de paisagem das relações internacionais depois do fim da Guerra Fria produziu novas conceituações a respeito de Estados que são percebidos como ameaça pelos Estados Unidos, o único superpoder remanescente, tanto para sua segurança nacional como para a ordem mundial. A mais comum dessas conceituações é o termo "Estado pária", adotado no vocabulário oficial de segurança da administração Clinton nos anos 90. Com a probabilidade de a "intervenção humanitária" transformar-se em um assunto cada vez mais importante na agenda internacional de Washington, o conceito de "Estado falido" foi inserido no debate político e acadêmico. Ambos os termos poderiam ser vistos como instrumentais para o incremento do novo intervencionismo americano. No entanto, uma terceira ameaça potencial para a estabilidade internacional tem sido completamente ignorada pelos Estados Unidos - ou por quaisquer outros formuladores de política externa de Estado: o "Estado cortesão", o qual, em sentido amplo, é um dos resultados do processo de globalização e de transformação do poder estatal. Mais precisamente, o "Estado cortesão" é um conceito analítico útil para a compreensão de certas ligações dos Estados com a economia global ilícita. Este ensaio considera que o conceito é crucial para se entender um aspecto fundamental da luta de poder que caracteriza as relações entre Estados no pós-Guerra Fria, e analisa o Estado cortesão através de sua dupla ligação em política internacional, com outros atores estatais legítimos, principalmente o superpoder global, e, simultaneamente, com atores globais não-estatais da economia ilícita.The changing landscape of international relations after the end of the Cold War has produced new conceptualizations of states perceived as a threat by the United States, the remaining and only superpower, to both its national security and the world order.

    To clarify clear the effect of the welding conditions and the heat treatment, alternating load tests were carried out in the endurance limit- and low-cycle-fatigue strength range on specimens of St E 47 and St E 70. Grounded basic material flat specimens cleared from their rolling skins and welded flat specimens with a butt weld of special quality were used. The welds were produced by the metal arc manual welding method with bar electrodes (low heat introduction) and with the submerged-arc welding method (high heat introduction). Part of the specimens were tempered free from stress after welding. The tests were carried out force-controlled at tension-repeated loading (S=0) and strain controlled at tension-compression alternating loading (S approx. -1). In the range of N = 5 x 10 4 ...1,5 x 10 6 cycles a small effect of the welding (special quality) for St E 47 with subsequence tempering on the endurance limit was proofed, which in comparison with the unwelded basic material (grounded surface) was characterized by broad range at nearly the same endurance limit. For St E 70, a clear decrease of the endurance limit of welded, tempered specimens (special quality) was found as compared with the basic material (grounded surface).

Seu acesso é modulado não apenas por múltiplos padrões distintivos (categoria socioeconômica, sexo, etnicidade, local de residência…, como também pelo tipo de rede escolar freqüentado (pública, particular. Este artigo analisa a constituição histórica e progressiva de uma escolarização em várias velocidades. O discurso político republicano, que insiste sobre a função homogeneizadora e igualitária da escola que socializa em comum e fabrica cidadãos iguais, foi se esvaziando progressivamente de sua substância. A heterogeneidade provocada pela atual fragmentação do sistema escolar brasileiro em várias redes reproduz, acentuando-as, as desigualdades sociais e compromete de modo durável o desenvolvimento econômico e social desse país.In Brazil, more than in any other Southern country, school is an unequally distributed social product. Access to it depends not only on such distinctive standards as socioeconomic position, sex, ethnicity, location of residence etc., but also on the type of network attended (public, private. This paper analyses the historical and progressive constitution of a multispeed schooling network. The republican political speech, which highlights the egalitarian and homogenizing function of school, has been gradually losing its substance. The heterogeneity resulting from the current fragmentation of the Brazilian schooling system into various networks reproduces, magnifying them, all social inequities and lastingly endangers the social and economical development of this country.

    The decay rate of the long-lived neutral K meson into the e^+ e^- e^+ e^- final state has been measured with the NA48 detector at the CERN SPS. Using data collected in 1998 and 1999, a total of 200 events has been observed with negligible background. This observation corresponds to a branching ratio of Br(K_L -> e^+ e^- e^+ e^-) = (3.30 + - 0.24_stat + - 0.23_sys + - 0.10_norm) x 10^-8.

    The state-of-the-art of the alcoholic fermentation for fuel alcohol production in Brazil shows that besides the great increase in production in the last twelve years, a significant advance in technology was achieved, both in the traditional batch fermentation (increased yields and productivity) and in the new large-scale multi-stage continuous fermentations. Large differences in technology level among distilleries show the need for improving technology transfer rates. Examples are presented and analyzed. (author) 7 figs., 5 tabs.

A amostra investigada foi constituída por 14 municípios do Estado do Rio Grande do Norte. A pesquisa envolveu coleta de dados referente às transferências, recursos próprios municipais e gastos com atenção básica. Na análise da gestão foi realizado um levantamento junto aos dirigentes locais e conselheiros. Observa-se que o financiamento do Sistema Único de Saúde se faz às expensas das transferências federais e receitas municipais, com pequena participação dos recursos estaduais. A direção dos gastos tem privilegiado a atenção básica. No processo de gestão, verifica-se centralização das ações nas prefeituras. As secretarias municipais e os conselhos cumprem em parte a legislação e apresentam dificuldades na autonomia e o controle social. Os resultados mostram que os instrumentos de planejamento e gestão são limitados em função das contradições presentes no contexto institucional, político e cultural no âmbito regional.This article investigates the issue of funding and the decentralization process in order to examine the composition, application and management of resources in the healthcare area.

    The literature has shown that tobacco use causes damage to the health of cigarette users, manifesting itself in diseases with high mortality. Among these diseases include respiratory failure, pulmonary emphysema and lung cancer, among others. On the other hand, smoking contributes significantly to increasing the dose of natural radiation received by man, due to the presence of uranium series radionuclides, such as {sup 226}Ra, {sup 210}Pb and {sup 210}Po, in relatively high concentrations in fresh tobacco leaves. The determination of these radionuclides in this matrix is of great interest, once they can be incorporated not only by the active smoker, but also by the passive smoker. The results of this study confirmed the significant presence of {sup 226}Ra and {sup 210}Pb in tobacco samples collected and analyzed. The average values of activity concentration found in samples from the State of Alagoas were of Bq.kg{sup -1} 0.8 to {sup 210}Pb and 183.5 Bq.kg{sup -1} to {sup 226}Ra. For samples coming from the State of Rio Grande do Sul, these values were 4,0 Bq.kg{sup -1} to {sup 210}Pb and 161.3 Bq.kg{sup -1} to {sup 226}Ra.

    Full Text Available Este artigo aborda a questão do avanço internacional do regime neoliberal, contexto da formulação de políticas que focalizam a pobreza, inclusive em países centrais. Em debates recentes, termos como 'cidadania' e 'democracia' têm sido sujeitos à interrogação crítica, revelando mudanças na relação cidadão/Estado que acompanham a hegemonia de critérios econômicos e a financeirização dos Estados nacionais. Argumentamos que tais processos globais requerem uma abordagem ampla, de uma perspectiva de economia política, capaz de iluminar como a substância da democracia e a legitimidade da autoridade estatal têm sido condicionadas pelo avanço de novos atores globais que representam os interesses do capital, favorecendo a concentração da riqueza e o aumento da pobreza, da desigualdade e da exclusão, e instaurando uma insegurança vital que atinge a maioria da população em nível mundial.This article analyses the advance of the neo-liberal regime, in order to contextualise the international formulation of policies focussed on poverty reduction. In recent debates, terms such as 'citizenship' and 'democracy' have been subject to critical scrutiny, revealing changes in the relations between citizens and the State which accompany the hegemony of economic criteria that put financial considerations at the centre of national states. We argue that analyses of such global processes require an ample political economy perspective, capable of illuminating how the substance of democracy and the legitimacy of state authority have been conditioned by the advance of new global entities that represent the interests of capital, favouring the concentration of wealth and the increase of poverty, inequality and exclusion, and installing a state of vital insecurity that affects the majority of the world's population.

    Full Text Available Lipossomas são vesículas constituídas de uma ou mais bicamadas fosfolipídicas orientadas concentricamente em torno de um compartimento aquoso e servem como carreadores de fármacos, biomoléculas ou agentes de diagnóstico. A estabilidade dos lipossomas pode ser afetada por fatores químicos, físicos e biológicos. Após administração intravenosa, lipossomas convencionais são rapidamente capturados pelo sistema fagocitário mononuclear. Para evitar essa captura, lipossomas furtivos foram desenvolvidos, os quais apresentam a superfície modificada com componentes hidrofílicos. Para permitir a liberação seletiva do fármaco nos sítios alvos, ligantes de reconhecimento específico são conjugados na superfície de lipossomas. Em geral, os métodos de preparação de lipossomas incluem hidratação de um filme lipídico seguida de sonicação ou extrusão para redução do tamanho das vesículas. Os lipossomas são caracterizados quanto ao tamanho e composição química das vesículas e conteúdo do material encapsulado. Nesta revisão, constata-se que os lipossomas oferecem maior eficácia e segurança com relação aos tratamentos convencionais. Apesar de algumas formulações lipossomais serem comercializadas desde os anos 1980 para tratamento de infecções fúngicas sistêmicas e do câncer, problemas de ordem tecnológica e biológica fazem com que os lipossomas sejam ainda extensivamente estudados para desenvolvimento de formulações estáveis no organismo visando à terapia de várias doenças, principalmente do câncer.Liposomes are vesicles that consist of one or more concentric phospholipidic bilayers organized around an aqueous inner compartment. They are carriers of drugs, biomolecules and diagnostic agents. The stability of liposomes can be influenced by chemical or physical factors. Once injected in the circulatory system, conventional liposomes suffer uptake by the mononuclear phagocytic system. To avoid such a capture

    Development of High-Fidelity Physics-Based Models to describe hypersonic flight through the atmospheres of Earth and Mars is underway at NASA Ames Research Center. The goal is to construct chemistry models of the collisional and radiative processes that occur in the bow shock and boundary layers of spacecraft during atmospheric entry that are free of empiricism. In this talk I will discuss our philosophy and describe some of our progress. Topics to be covered include thermochemistry, internal energy relaxation, collisional dissociation and radiative emission and absorption. For this work we start by solving the Schrodinger equation to obtain accurate interaction potentials and radiative properties. Then we invoke classical mechanics to compute state-specific heavy particle collision cross sections and reaction rate coefficients. Finally, phenomenological rate coefficients and relaxation times are determined from master equation solutions.

    Full Text Available Os dados coletados na cidade de Maringá, Estado do Paraná, referentes ao consumo e à aceitação do leite e seus derivados foram utilizados para se traçar o perfil do consumo desses produtos, gerando subsídios para entendimento mais amplo sobre o mercado consumidor de leite. Trezentos indivíduos responderam à pesquisa que avaliou o grau de aceitação e frequência de consumo do leite e produtos derivados. Observou-se que o mais importante para o consumidor, no momento da compra, encontra-se na relação entre preço e qualidade do produto, e aproximadamente metade dos entrevistados (48,17% tem preferência pelo leite integral, seguido pelo desnatado com 26,20%. Entretanto,constatou-se que 8,73% dos entrevistados declararam não consumir leite, e a maior parte dos casos justifica-se por possuírem algum nível de intolerância à lactose. Enquanto isso, o iogurte e os queijos foram apontados como os derivados com maior percentual defrequência de consumo e aceitação. De forma geral, os dados coletados permitem concluir que o leite e seus derivados são produtos consumidos com regularidade e seus derivados foram apontados com alto percentual de frequência de consumo e aceitação.Data collected in Maringá, Paraná State, on the acceptance and consumption of milk and its products were used to delineate the profile of consumption of these products, generating benefits for a better understanding of the consumer market for milk.

  16. VNI version 4.1. Simulation of high-energy particle collisions in QCD: Space-time evolution of e+e-... A + B collisions with parton-cascades, cluster-hadronization, final-state hadron cascades

    VNI is a general-purpose Monte-Carlo event-generator, which includes the simulation of lepton-lepton, lepton-hadron, lepton-nucleus, hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions. It uses the real-time evolution of parton cascades in conjunction with a self-consistent hadronization scheme, as well as the development of hadron cascades after hadronization. The causal evolution from a specific initial state (determined by the colliding beam particles) is followed by the time-development of the phase-space densities of partons, pre-hadronic parton clusters, and final-state hadrons, in position-space, momentum-space and color-space. The parton-evolution is described in terms of a space-time generalization of the familiar momentum-space description of multiple (semi)hard interactions in QCD, involving 2 → 2 parton collisions, 2 → 1 parton fusion processes, and 1 → 2 radiation processes. The formation of color-singlet pre-hadronic clusters and their decays into hadrons, on the other hand, is treated by using a spatial criterion motivated by confinement and a non-perturbative model for hadronization. Finally, the cascading of produced prehadronic clusters and of hadrons includes a multitude of 2 → n processes, and is modeled in parallel to the parton cascade description. This paper gives a brief review of the physics underlying VNI, as well as a detailed description of the program itself. The latter program description emphasizes easy-to-use pragmatism and explains how to use the program (including simple examples), annotates input and control parameters, and discusses output data provided by it

    This aim of work is the geological and geochronological study of rocks cropping out on Cardoso Island, on the southeastern coast of Sao Paulo States, close to be boundary with Parana State. The Island with an area of about 151 km{sup 2} is a protected area administered by the Forest Institute of Environment Secretariat of the State of Sao Paulo. It is mountanious, with a peak at 814 m, and is covered by dense Mata Atlantica vegetation. The terrains which compose the island are mainly an igneous complex with light grey leucocratic, inequigranular, medium - to coarse-grained syenites. The predominant Tres Irmaos Syenite (STI), composed of pyroxene, hornblende, and perthitic to mesoperthitic microcline, has a magmatic flow structures, and is cut by the Cambriu alkali-feldspar Granites (GC), which is pinkish grey, leucocratic and medium-grained. Geochemical analysis of STI and GC demonstrate their meta luminous alkaline nature and late-orogenic to an orogenic character. The geochronological results suggest that the bodies were formed between 620 and 570 My according to the U-Pb method in zircons, with cooling between 597 and 531 My (K-Ar in amphiboles). Whole rock Sm-Nd analysis yield T{sub DM} ages in the Meso and Paleoproterozoic (1.200 - 2.200 My). belt of low grade meta sedimentary rocks occurs in the northern part of the island. Quartz schist, quartz-mica schist and mica-quartz schist, often containing andaluzite and cordierite, predominate. The geochemical and geochronological data suggest that the sources of the metasediments were andesites of continental arc whose protolities separated from the mantle during the Paleoproterozoic, between 1.800 and 2.200 My. These metasediments probably continue on the continent in the Taquari region and extend southwards in narrow strips between the granitoids of the Paranagua Domain. Although quaternary deposits are expressive, they were not studied in details since they were not the objectives of this study. (author)

    This article examines four movements of the religiously orthodox that should have failed according to most social movement theory and research. The movements combine (1) an extraordinarily broad agenda, (2) a strict, morally absolutist ideology, and (3) a strong proscription against compromise with other groups, each of which has been identified as a liability that can lead to movement failure. Through inductive, qualitative analyses, the authors identify four shared strategies that helped these movements overcome these obstacles: bypassing the state, building grassroots structures, providing graduated membership, and reprioritizing agendas. Analyses of these movements also suggest that particular combinations of movement "liabilities" may actually be advantageous.

    The quantum interference between the two parts of the optical Schrodinger-cat state makes possible to construct a wide class of quantum states via discrete superpositions of coherent states. Even a small number of coherent states can approximate the given quantum states at a high accuracy when the distance between the coherent states is optimized, e. g. nearly perfect Fock state can be constructed by discrete superpositions of n + 1 coherent states lying in the vicinity of the vacuum state.

Para isso, foram utilizados dados de 169 experimentos conduzidos no período de 1974 a 2004 e que envolveram 16 locais e três safras. A média da cultivar Carioca, comum em todos os experimentos, foi utilizada como estimador do efeito ambiental e a média das cinco melhores linhagens sob avaliação de cada biênio, como efeito fenotípico. A diferença entre essas duas médias forneceu o desvio genético. O coeficiente de regressão linear entre desvio genético Y (variável dependente e o biênio X (variável independente forneceu a estimativa do progresso genético. As interações linhagens x safras e linhagens x anos foram, na maioria dos casos, significativas, contudo, suas contribuições para a variação total foram inferiores a de linhagens x locais. Desse modo, fica clara a necessidade de que os experimentos sejam conduzidos em um maior número de locais.

    We study relativistic equations for bound states of two-body systems using Dirac`s constraint formalism and supersymmetry. The two-body system can be of spinless particles, one of them spinning and the other one spinless, or both of them spinning. The interaction is described by scalar, timelike four-vector and spacelike four-vector potentials under Lorentz transformations. As an application we use the relativistic wave equation for two scalar particles and calculate the mass spectra of the mesons treating them as spinless quark-antiquark bound states. The interaction potential in this case is a convenient adaptation of the potential employed in non-relativistic calculations. Finally, we compare our results with more recent experimental data and with theoretical results obtained with the same potential used by us but with a non-relativistic wave equation. We also compare our results with results obtained with the relativistic wave equation but with a different interaction potential. (author). 38 refs, 9 figs, 8 tabs.

    This paper analyzes the causes and scope of the nuclear energy diffusion process in the capitalist world. It also aims at explaining Brazil's role in this process. The study contemplates two main concepts that are, here, considered to be driving and directing vectors: the World Capital and the Capitalist State. According to the expanded reproduction logic, World Capital forms the world nuclear productive subsystem, which commands and directs, in this process, hundreds (or thousands) of productive units, regardless of their geographical location, nationality or capital control. Thru the utilization of available public intervention tools, the Capitalist state has favored the formation of the world nuclear productive subsystem, thus guiding the accumulation process in the interior of this system. Therefore, the conclusion of the Nuclear Cooperation Agreement between Brazil and Germany and the resultant establishment of the Brazilian Nuclear Program (following the authoritarian model of public administration), is well fitted in the general dynamics of subordination/articulation of the Brazilian economy to the world economy and, particularly, to the world nuclear productive subsystem.

    The electric energy is an important tool to rural communities, promoting quality of life through its use at home or as part of the productive process. The Rural Electrical Project of the State of Goias began with the collaboration between The Overseas Economic Cooperation Fund (OECF) and the Electric Company of the State of Goias. The subject of this paper is to characterize the electric energy use in three farms attended by OECF project, in Rio Verde, Jatai and Mineiro. It was done the checking, analysis and description of situations related to the electric installation, motors starting, conservation and use of alternative energy source. It was evident that all farms use electric motors to several purposes (irrigation, manufacture of ration, triturates, mechanic milking, etc). Two farms used electric fences, while only one used hybrid system. It was verified at the visited farms presented an expressive use of the electric energy in its domestic usage as much as an input to the productive process. (author)

    Full Text Available O autor procura entender por que processos de paz não são eficazes em estabelecer uma paz estável e duradoura depois que conflitos intra-estatais são encerrados. Ele argumenta que a insistência na construção de Estados em regiões marcadas por conflitos intra-estatais pode explicar a falha de grande parte dos processos de paz. Afirma, então, que o "elo que falta" nas explicações apresentadas por boa parte da literatura sobre resolução de conflitos é a questão da construção de identidades. Em seguida, explora como alguns autores lidam com o tema da identidade para defender uma postura influenciada pelos escritos de Habermas sobre comunicação, política e Estado. Na conclusão, avalia o processo de peacebuilding na Bósnia, e afirma que, longe do fracasso que muitos atribuem a esse processo, a intervenção naquele país conseguiu suspender as hostilidades e iniciar um processo político lento que pode levar a uma nova configuração política, diferente do Estado-nação, entre as partes. Finalmente, o autor afirma que o referido processo pode fornecer elementos fundamentais para a transição política agora em curso no Iraque, após a invasão americana em 2003.The author tries to explain why intra-state conflicts are less likely to be successfully concluded by peaceful settlements than inter-state conflicts. The author affirms that his main hypothesis is that those peace processes fail because they insist on building states as the only possible political space. The author argues that the missing link in the existing literature on conflict resolution is the social construction of identities involved in such conflicts. He discusses how different authors deal with identity construction before he settles for a position defended by Habermas, which relies on new ideas on communication, politics and the state. The author concludes his argument by evaluating the Dayton agreement in Bosnia. According to the author, the Dayton

As redes políticas de poder são definidas neste artigo como conexões de interesses envolvendo, basicamente, empresários e cargos políticos no aparelho de Estado, no executivo, legislativo e no judiciário e, também, em outros espaços de poder buscando assegurar vantagens e privilégios para os participantes. Além da ideologia que lhe reforça a legitimidade, as redes podem utilizar artifícios tais como o nepotismo, o clientelismo e a corrupção. O estado do Paraná é apresentado como exemplo de modernidade, de racionalidade, de adesão aos valores e às práticas de um capitalismo regido pelos princípios de impessoalidade e de eficiência. Neste artigo mostraremos que isso é um mito. Para tanto, procederemos à genealogia de famílias que detêm poder e riqueza na atualidade, mas que estão associadas aos interesses dominantes há quase 300 anos. Nomes ilustres da política e da economia compõem uma surpreendente e intricada rede de relações familiares, de parentesco e de privilegiamento que assegura a estrutura do poder nas mais diversas conjunturas econômicas e políticas.The structure of power is not an abstraction; it is materialised in objective situations of possession of wealth, and is reproduced and consolidated thanks to political, social, and kinship networks.

    The recent moves towards the insertion of biofuels in the energy matrix of a number of countries are opening new prospects for agricultural production and for agroindustrial chains. This study aims at understanding the mechanisms taking place within a production system geared towards biodiesel production. The emergence of this new productive base raises new research issues: in what circumstances are the structuring, organization and implementation of these biodiesel productive chains taking place in Brazil? What are the effects of biodiesel production on local economies? Hence, the central objective of this study is the development and validation of an analytical structure capable of characterizing the biodiesel productive arrangements and identifying their economic and social impacts at the regions where they are installed. A preliminary analysis identified that a biodiesel productive arrangement is emerging in the State of Piaui, Northeastern Brazil, Our theoretical basis comprises elements from the regional economy, biorefineries, local production arrangements and innovation. For the analyses, we employed the methods of input-output, local quotient and shift-share. It can be said that a new social-economic dynamics is taking place in Piaui; however, the company needs to assess its interaction with local institutions as well as its castor bean production strategies.

    The first part of our analysis uses the wavelet method to compare the quantum chromodynamic (QCD) prediction for the ratio of hadronic to muon cross sections in electron-positron collisions, R, with experimental data for R over a center of mass energy range up to about 7 GeV. A direct comparison of the raw experimental data and the QCD prediction is difficult because the data have a wide range of structures and large statistical errors and the QCD description contains sharp quark-antiquark thresholds. However, a meaningful comparison can be made if a type of ''smearing'' procedure is used to smooth out rapid variations in both the theoretical and experimental values of R. A wavelet analysis (WA) can be used to achieve this smearing effect. The second part of the analysis concentrates on the 3.0-6.0 GeV energy region which includes the relatively wide charmonium resonances ψ(1{sup -}). We use the wavelet methodology to distinguish these resonances from experimental noise, background and from each other, allowing a reliable determination of the parameters of these states. Both analyses are examples of the usefulness of WA in extracting information in a model independent way from high energy physics data. (orig.)

    The data taken with the OPAL detector at LEP at center of mass energies between 183 and 202 GeV during the years 1997-1999 have been used to search for neutral Higgs-Bosons and to investigate the pair production of Z-bosons. The analyses performed concentrate on final states with two τ-leptons and two quark-jets. Neutral Higgs boson production has been searched for in the framework of the standard model where the Higgs boson is produced in association with a Z boson. Also the Higgs production of the minimal supersymmetric extension of the standard model (MSSM) has been investigated via the pair production process of the h and A Higgs bosons. No significant excess of the number of observed events compared to the background expectation has been observed. Limits on the masses of Higgs bosons are derived from the combination of all search channels. In addition the pair production of Z bosons which is the most important background process in the search for Higgs bosons has been investigated. The production cross section and limits on anomalous couplings on the ZZZ- and ZZγ-vertices which are not predicted by the standard model are derived from the combination of channels. (orig.)

    gain access to this market it is important to understand the distribution system used for fresh produce in the United States.Devido ao crescente número de imigrantes nos EUA, composto por latinos, brasileiros, asiáticos e africanos, observou-se um aumento no interesse dessas comunidades em obter produtos que são comuns em seus países de origem. Para atender essa demanda houve um aumento nas importações de produtos étnicos e na produção interna dessas hortaliças. A mandioca é um bom exemplo do interesse em cultivos étnicos. As importações desse produto cresceram 370% nos últimos seis anos. A Universidade de Massachusetts iniciou suas pesquisas em 1996 com culturas populares entre os imigrantes de Porto Rico e Republica Dominicana e, em 2002, com os vegetais presentes na culinária brasileira. Este trabalho sumariza as informações disponíveis atualmente em relação às necessidades dos imigrantes brasileiros em termos de hortaliças de cunho cultural, identifica as cadeias fornecedoras existentes, explica os impactos da mídia sobre o mercado étnico e descreve as práticas de aquisição de produtos específicos demandados pelos consumidores brasileiros. Pesquisas mostraram que a maioria dos imigrantes brasileiros eram provenientes do estado de Minas Gerais e devido a esse fator, as culturas escolhidas foram jiló, maxixe, taioba, abóbora e quiabo. Para a introdução dos produtos no mercado é necessário focar grande parte das atenções no marketing e divulgação. Apesar de existir uma demanda, esses vegetais não são normalmente encontrados nos mercados, sendo necessário informar onde e quais produtos estão disponíveis. O melhor meio de divulgação entre os brasileiros é através da emissora de TV Rede Globo, porém outros meios como jornais e rádios em língua portuguesa são eficientes e mais acessíveis. A exportação de produtos étnicos para os EUA é um mercado crescente, porém para entrar nesse mercado é necessário compreender

    Gamma-ray spectrometry, electrical resistivity, and magnetic susceptibility measurements were taken from agricultural areas near the City of Maringa, in the Northwest region of the Parana state, south Brazil, in order to characterize the spatial distribution of radionuclides (K, eU, and eTh), the apparent resistivity, and the magnetic susceptibility determined for soils. Three different types of soils are present in this agricultural area: Alfisoil, clayey texture Oxisoil, both deriving from Lower Cretaceous basalts of the Serra Geral Formation; and medium texture Oxisoil from reworked Serra Geral and Goio-Ere formations, the latter deriving from sandstones of the Upper Cretaceous Caiua Group. It could be observed that in more clayey soils both concentration of radionuclides and susceptibility values are higher than in more sandy soils, especially due to the higher adsorption in the former and to the higher availability of magnetic minerals in the latter. The average ppm and Bq Kg{sup -1} grades for K, eU, and eTh in the areas under anthropic activity are of 1766-54.75, 0.83-10.22, and 1.78-7.27, respectively. These grades are significantly higher than those of non-occupied or non-fertilized areas (1101-34.15 K, 0.14-1.69 eU, and 1.31-5.36 eTh in ppm and Bq Kg-1, respectively.) Correlations were observed between uranium and clay, uranium and magnetic susceptibility, uranium and organic matter, and between electric resistivity and clay grades. Varied concentrations of radionuclides were also observed in different fertilizer formulations applied to soy and wheat cultures. Apparent electric resistivity values between 25 and 647 Ohm.m and magnetic susceptibility values between 0.28 e 1.10 x 10-3 SI due to clay and magnetic minerals represented important soil discrimination factors in the study area that can be incorporated as easy, low-cost soil mapping tools.

    This note presents the first collider search for light scalar particles that could contribute to the accelerating expansion of the observable universe. The results are based on a re-interpretation of a search for top super-partners using the $t\\bar{t}+E_{T}^{\\text{miss}}$ signature and a search for dark matter using the mono-jet signature. The analysis uses a dataset of LHC $pp$ collision events collected with the ATLAS detector at $\\sqrt{s}=13$ TeV corresponding to an integrated luminosity of 36.1~fb$^{-1}$. No significant excess over the predicted background is observed. The search allows to set the most stringent constraints on the suppression scale of conformal and disformal couplings of dark energy to standard model matter in the context of an effective field theory of dark energy.

Para tanto, analisaram-se os dados do Projeto LUPA (Levantamento Censitário de Unidades de Produção Agrícola do Estado de São Paulo e de consultas aos fruticultores de diversas regiões paulistas. Verificou-se a existência de 6 famílias botânicas, 11 gêneros e 12 principais espécies de frutíferas e uma de noz de clima temperado. São elas, em ordem decrescente do número de plantas: videira rústica, videira fina, pessegueiro (incluindo nectarineira, figueira, caquizeiro, nogueira-macadâmia, macieira, ameixeira, pereira européia, pereira asiática, nespereira, quivizeiro e marmeleiro, sendo as duas primeiras responsáveis por 51% de toda a área ocupada com as referidas culturas de clima temperado. Constatou-se que esse segmento da fruticultura está sendo praticado em 9.510 propriedades de 65% dos municípios paulistas, englobando todas as 40 regionais agrícolas da CATI (Coordenadoria de Assistência Técnica e Integral, existentes no Estado. A videira e a pereira foram as únicas culturas que apresentaram mais de uma espécie botânica sendo cultivada comercialmente. Foram detectadas 53 principais cultivares, sendo a cultura do pessegueiro responsável pela maior fonte de diversidade varietal. Considerando as épocas de colheita das frutíferas e nozes pesquisadas, observaram-se produções de frutos em todos os meses do ano, especialmente entre outubro e abril. Registraram-se novos e importantes nichos de cultivo nas regiões de Jales, Presidente Prudente, Barretos e Jaú, com predominância das uvas finas, das pêras asiáticas, dos pêssegos adaptados e da nogueira-macadâmia, respectivamente.During the period of 1998 to 2002 it was investigated, through the LUPA census (Levantamento Censitário de Unidades de Produção Agr

    O objetivo deste trabalho foi o de avaliar a adaptabilidade e a estabilidade de cultivares de algodão (Gossypium hirsutum L., utilizando a metodologia proposta por Eberhart & Russell (1966. Para tanto, onze variedades de algodão foram avaliadas em sete locais do Estado do Mato Grosso, Brasil, em dois anos agrícolas (2002/2003 e 2003/2004. O delineamento experimental empregado foi o de blocos casualizados com quatro repetições e as características avaliadas foram a produtividade de algodão em caroço e a porcentagem de fibra. Com relação à produção de algodão em caroço, as cultivares BRS Aroeira, BRS Ipê, BRS Cedro, BRS Jatobá e Delta Opal demonstraram ampla adaptabilidade e estabilidade para as regiões produtoras do Estado. Entretanto, considerando a porcentagem de fibra, não foram encontradas cultivares de algodão com ampla adaptabilidade e estabilidade nos ambientes estudados.
