The Physical Activity Promotion Environment In Mexican Health Care Settings

Purpose: The health care environment is recognized as a promising setting in which to promote physical activity (PA). Nearly 40% of Mexican adults are inactive and whether Mexican health care environments are promoting PA is unknown. The purpose of this study was to describe and compare the PA promotion environment in Guadalajara, Mexico. Methods: Forty primary care clinics and hospitals from the three health care systems in Guadalajara were sampled: 15 from the Secretary of Health, 14 from the Social Security Institutes and 11 from the private sector. A tool for measuring the PA environment of health care settings, including the availability of written PA materials, was developed. Face validity and inter-rater reliability of the tool were established (kappa=.75). Level of care (primary, secondary, and tertiary), number of floors and type of health care system of each clinic and hospital were also recorded. The tool was then used to assess the availability, accessibility, visibility, signage, cleanliness, and safety of all stairs, elevators, and green spaces at each health care setting and to record the presence of written PA materials including posters, brochures, leaflets, flyers, articles, and ‘cartels’ (hand-made posters) in the foyer and one waiting room of each clinic and hospital. Results: Thirty (75%) clinics and hospitals had stairs, 17 (42%) had elevators, 22 (55%) had green spaces and 11 (28%) had promotional PA materials (only posters or cartels). The availability of PA posters/cartels was significantly associated with health care system type (X2(2)=8.11, p\u3c.05) and with level of care (X2(2)=6.68, p\u3c.05), where primary care clinics from the Secretary of Health had significantly more PA promotional materials than clinics and hospitals from the other two systems. The health care PA environment score reflected by the stair, elevator, and green space indicators was not significantly different between the three Mexican health care systems (p\u3e.05); the score was low across the three systems (Mean=3.7, SD=2.7, Range=-2-10). Conclusions: Mexican health care settings are not PA friendly. Interventions to enhance the PA promotion environment in the three Mexican health care systems are needed to reach inactive patients

Numerical evolution of multiple black holes with accurate initial data

We present numerical evolutions of three equal-mass black holes using the moving puncture approach. We calculate puncture initial data for three black holes solving the constraint equations by means of a high-order multigrid elliptic solver. Using these initial data, we show the results for three black hole evolutions with sixth-order waveform convergence. We compare results obtained with the BAM and AMSS-NCKU codes with previous results. The approximate analytic solution to the Hamiltonian constraint used in previous simulations of three black holes leads to different dynamics and waveforms. We present some numerical experiments showing the evolution of four black holes and the resulting gravitational waveform.Comment: Published in PR

Determining the 7Li(n,gamma) cross section via Coulomb dissociation of 8Li

The applicability of Coulomb dissociation reactions to determine the cross section for the inverse neutron capture reaction was explored using the reaction 8Li(gamma,n)7Li. A 69.5 MeV/nucleon 8Li beam was incident on a Pb target, and the outgoing neutron and 7Li nucleus were measured in coincidence. The deduced (n,gamma) excitation function is consistent with data for the direct capture reaction 7Li(n,gamma)8Li and with low-energy effective field theory calculations.Comment: Accepted for publication in Phys.

Deformation Quantization of Fermi Fields

Deformation quantization for any Grassmann scalar free field is described via the Weyl-Wigner-Moyal formalism. The Stratonovich-Weyl quantizer, the Moyal $\star$-product and the Wigner functional are obtained by extending the formalism proposed recently in [35] to the fermionic systems of infinite number of degrees of freedom. In particular, this formalism is applied to quantize the Dirac free field. It is observed that the use of suitable oscillator variables facilitates considerably the procedure. The Stratonovich-Weyl quantizer, the Moyal $\star$-product, the Wigner functional, the normal ordering operator, and finally, the Dirac propagator have been found with the use of these variables.Comment: 19+1 pages, no figures, revtex4 file styl

Chronic Postoperative Pain

Understanding the definition of pain has imposed numerous challenges toward pain practitioners. The pain experience phenomena are complicated to understand, and this construct goes beyond biomedical approaches. Persistent pain as a disease implicates changes that include modified sensory feedback within the somatosensory system. It has been documented that different anatomical restructuring in nociceptive integration and adaptations in nociceptive primary afferents and perception conduits are present in persistent pain situations. Chronic postoperative pain (CPOP) is known as a particular disorder, not only associated with a specific nerve damage or manifestation of a unique inflammatory response but also with a mixture of both. The occurrence of CPOP varies substantially among the literature and depends on the kind of procedure. There are reports informing that 10 to 50% of the patients undergoing common procedures had CPOP, and 2 to 10% of patients complained of severe pain. Systematic review has been performed trying to identify the Holy Grail, none showed sufficient evidence to guide CPOP treatment, and multimodal approaches must be tried in large randomized controlled trials (RCTs) to provide robust evidence as evidence-based management for CPOP still lacking

Dynamic studies of 11Li and its core 9Li on 208Pb near the Coulomb barrier

We measured the scattering of the halo nucleus 11Li and its core 9Li on the lead target at TRIUMF at energies below and around to the Coulomb barrier. We report here on our preliminary analysis of the inclusive breakup reaction

Li-11 structural information from inclusive break-up measurements

IWM-EC 2014 – International Workshop on Multi facets of EoS and Clustering.-- et al.Structure information of 11Li halo nucleus has been obtained from the inclusive break-up measurements of the 11Li+208Pb reactions at energies around the Coulomb barrier (Elab = 24.3 and 29.8 MeV). The effective break-up energy and the slope of B(E1) distribution close to the threshold have been extracted from the experimental data.Peer Reviewe

Scattering of 11 Be around the Coulomb barrier

Preliminary results on the 11Be+120Sn quasielastic scattering as well as the 11Be → 10Be + n breakup channel are presented in this work. The angular distributions of these channels were measured at REX-ISOLDE-CERN. The accuracy and angular range of the presented results provide stronger constrains to the theoretical interpretation than existing published results. We compare these new data with coupled-channel (CC) and continuum-discretized coupled-channel (CDCC) calculations. The role played by transfer and breakup channels in the elastic scattering is discussed.CICYT FPA2007- 62170MEC FINURA (FPA2007-63074) CPAN (CSD 2007-00042)DGICYT FPA2006-13807-c02-01 CSD-2007-0004

Probing proton halo effects in the 8B+64Zn collision around the Coulomb barrier

Proton halo effects in the 8B+64Zn reaction at an energy around 1.5 times the Coulomb barrier have been studied at HIE-ISOLDE CERN using, for the first time, the only existing postaccelerated 8B beam. This, together with the use of a high granularity and large solid angle detection system, allowed for a careful mapping of the elastic angular distribution, especially in the Coulomb-nuclear interference region. Contrary to what is observed for the one-neutron halo nucleus 11Be on the same target in a similar energy range, the analysis of the elastic scattering angular distribution shows only a modest suppression of the Coulomb-nuclear interference peak, with no remarkable enhancement of the total reaction cross-section. Inclusive angular and energy distributions of 7Be produced in direct reaction processes have also been measured. The comparison of these data with the results of theoretical calculations for the elastic and non-elastic breakup contributions indicate that both processes are important. Overall, the experimental data suggest a 8B collision dynamics at the barrier very different from the one of neutron halo nuclei, showing only modest effects of coupling to continuum. This behaviour can be interpreted as due to the presence of the additional Coulomb interactions halo-core and halo-target together with the presence of the centrifugal barrier felt by the valence proton of 8B
