Measurement of Direct-Photon Cross Section and Double-Helicity Asymmetry at sqrt[s]=510 GeV in p[over →]+p[over →] Collisions.

We present measurements of the cross section and double-helicity asymmetry A_{LL} of direct-photon production in p[over →]+p[over →] collisions at sqrt[s]=510  GeV. The measurements have been performed at midrapidity (|η|<0.25) with the PHENIX detector at the Relativistic Heavy Ion Collider.

Probing Gluon Spin-Momentum Correlations in Transversely Polarized Protons through Midrapidity Isolated Direct Photons in p^{↑}+p Collisions at sqrt[s]=200 GeV.

Studying spin-momentum correlations in hadronic collisions offers a glimpse into a three-dimensional picture of proton structure. The transverse single-spin asymmetry for midrapidity isolated direct photons in p^{↑}+p collisions at sqrt[s]=200  GeV is measured with the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). Because direct photons in particular are produced from the hard scattering and do not interact via the strong force, this measurement is a clean probe of initial-state spin-momentum correlations inside the proton and is in particular sensitive to gluon interference effects within the proton.

[Impact of an information campaign on cardiovascular risk factors. 5-year results at the study town Epernon].

Objectives: Information campaigns are implemented to improve knowledge of cardiovascular disease and risk factors. The impact of these programs must be evaluated to determine whether they truly contribute to modifying risk factors in the population.

Methods: A 5-year information campaign on cardiovascular disease and risk factors was conducted in Epernon, France.

[Effects of an educational campaign on cardiovascular risk factors in a French town (Epernon, study town). Methods and preliminary results: prevalence and level of risk factors].

The authors report the methods and preliminary findings of a study scheduled to last 5 years, which aims to evaluate cardiovascular risk factor changes in response to an education program. The population sample consisted of 961 subjects, from Epernon itself (the study town) and from two control towns. The assessment criteria were reported at the beginning of the study and then again after 2 and 5 years.
