A ENFERMEIRA OBSTETRA E A POLĂTICA DE HUMANIZAĂĂO DO PARTO: EM BUSCA DE MUDANĂA NO MODELO ASSISTENCIAL.
Estudio de naturaleza cualitativa cuyos objetivos son: identificar las caracterĂsticas de la asistencia dada por Enfermeras Obstetras al trabajo de parto y parto normal en un Hospital-Maternidad que prima por la humanizaciĂłn del parto y asociar los resultados observados con la propuesta de humanizaciĂłn del parto y la asistencia prestada por las Enfermeras Obstetras a los cambios en el modelo asistencial. El pĂșblico albo constĂł de seis Enfermeras Obstetras que actĂșan en la asistencia al parto en un Hospital-Maternidad de la ciudad de RĂo de Janeiro. Los instrumentos usados fueron: entrevista y cuestionario semi-estructurados. Del anĂĄlisis de los datos surgieron dos categorĂas temĂĄticas: el intento de humanizar las intervenciones en la asistencia al parto y el significado de la humanizaciĂłn del parto para las enfermeras obstetras. Nosotros
concluimos que el cambio todavĂa es lento. Las ponentes sienten la necesidad de cambio y reconocen la importancia de la presencia del acompañante en el pre parto y en la sala de parto. La resistencia impuesta por la clase mĂ©dica es seguramente el mayor impedimento para la actuaciĂłn de la enfermera en la asistencia en el parto. Tal conflicto no impide cuidar a la mujer en el trabajo del parto, poniendo en prĂĄctica estrategias propias, prestando un cuidado diferenciado y ganando su espacio en el ĂĄrea obstĂ©trica.Estudo de natureza qualitativa, cujos objetivos foram: identificar a assistĂȘncia prestada pelas enfermeiras obstĂ©tricas no trabalho de parto e o parto numa maternidade que prima pela polĂtica

Differential branching fraction and angular analysis of the decay B0âKâ0ÎŒ+ÎŒâ
The angular distribution and differential branching fraction of the decay B 0â K â0 ÎŒ + ÎŒ â are studied using a data sample, collected by the LHCb experiment in pp collisions at sâ=7 TeV, corresponding to an integrated luminosity of 1.0 fbâ1. Several angular observables are measured in bins of the dimuon invariant mass squared, q 2. A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be q20=4.9±0.9GeV2/c4 , where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions
Observation of two new baryon resonances
Two structures are observed close to the kinematic threshold in the mass spectrum in a sample of proton-proton collision data, corresponding
to an integrated luminosity of 3.0 fb recorded by the LHCb experiment.
In the quark model, two baryonic resonances with quark content are
expected in this mass region: the spin-parity and
states, denoted and .
Interpreting the structures as these resonances, we measure the mass
differences and the width of the heavier state to be
MeV,
MeV,
MeV, where the first and second
uncertainties are statistical and systematic, respectively. The width of the
lighter state is consistent with zero, and we place an upper limit of
MeV at 95% confidence level. Relative
production rates of these states are also reported.Comment: 17 pages, 2 figure
Observation of associated production of a boson with a meson in the~forward region
A search for associated production of a boson with an open charm meson is
presented using a data sample, corresponding to an integrated luminosity of
of proton--proton collisions at a centre-of-mass energy
of 7\,TeV, collected by the LHCb experiment. %% Seven candidate events for
associated production of a boson with a meson and four candidate
events for a boson with a meson are observed with a combined
significance of 5.1standard deviations. The production cross-sections in the
forward region are measured to be where the first uncertainty is statistical and the
second systematic.Comment: 18 pages, 2 figure

decay modes. In addition, ratios of these lifetimes, and the ratio of the

the system, , are
reported. All quantities are found to be consistent with Standard Model
expectations.Comment: 28 pages, 4 figures. Updated reference
Measurements of the branching fractions of B+âppK+ decays
The branching fractions of the decay B+ â ppÌK+ for different intermediate states are measured using data, corresponding to an integrated luminosity of 1.0 fb-1, collected by the LHCb experiment. The total branching fraction, its charmless component MppÌ < 2.85 GeV/c2 and the branching fractions via the resonant ccÌ states η c(1S) and Ï(2S) relative to the decay via a J/Ï intermediate state are [Equation not available: see fulltext.] Upper limits on the B + branching fractions into the η c(2S) meson and into the charmonium-like states X(3872) and X(3915) are also obtained
Search for the decay Bs0âD*âϱ
A search for the decay Bs0âD*âϱ is presented using a data sample corresponding to an integrated luminosity of 1.0ââfb-1 of pp collisions collected by LHCb. This decay is expected to be mediated by a W-exchange diagram, with little contribution from rescattering processes, and therefore a measurement of the branching fraction will help us to understand the mechanism behind related decays such as Bs0âÏ+Ï- and Bs0âDD- . Systematic uncertainties are minimized by using B0âD*âϱ as a normalization channel. We find no evidence for a signal, and set an upper limit on the branching fraction of B(Bs0âD*âϱ)<6.1(7.8)Ă10-6 at 90% (95%) confidence level
Study of B0(s)âK0Sh+hâČâ decays with first observation of B0sâK0SK±Ïâ and B0sâK0SÏ+Ïâ
A search for charmless three-body decays of B 0 and B0s mesons with a K0S meson in the final state is performed using the pp collision data, corresponding to an integrated luminosity of 1.0 fbâ1, collected at a centre-of-mass energy of 7 TeV recorded by the LHCb experiment. Branching fractions of the B0(s)âK0Sh+hâČâ decay modes (h (âČ) = Ï, K), relative to the well measured B0âK0SÏ+Ïâ decay, are obtained. First observation of the decay modes B0sâK0SK±Ïâ and B0sâK0SÏ+Ïâ and confirmation of the decay B0âK0SK±Ïâ are reported. The following relative branching fraction measurements or limits are obtained B(B0âK0SK±Ïâ)B(B0âK0SÏ+Ïâ)=0.128±0.017(stat.)±0.009(syst.), B(B0âK0SK+Kâ)B(B0âK0SÏ+Ïâ)=0.385±0.031(stat.)±0.023(syst.), B(B0sâK0SÏ+Ïâ)B(B0âK0SÏ+Ïâ)=0.29±0.06(stat.)±0.03(syst.)±0.02(fs/fd), B(B0sâK0SK±Ïâ)B(B0âK0SÏ+Ïâ)=1.48±0.12(stat.)±0.08(syst.)±0.12(fs/fd)B(B0sâK0SK+Kâ)B(B0âK0SÏ+Ïâ)â[0.004;0.068]at90%CL
Observation of the decay B+câBÂșsÏ+
The result of a search for the decay B+câBÂșsÏ+ is presented, using the BÂșsâDs-Ï+ and BÂșsâJ/ÏÏ channels. The analysis is based on a data sample of pp collisions collected with the LHCb detector, corresponding to an integrated luminosity of 1ââfb-1 taken at a center-of-mass energy of 7 TeV, and 2ââfb-1 taken at 8 TeV. The decay B+câBÂșsÏ+ is observed with significance in excess of 5 standard deviations independently in both decay channels. The measured product of the ratio of cross sections and branching fraction is [Ï(Bc+)/Ï(BÂșs)]ĂB(Bc+âBÂșsÏ+)=[2.37±0.31â(stat)±0.11â(syst)-0.13+0.17(ÏBc+)]Ă10-3, in the pseudorapidity range 2<η(B)<5, where the first uncertainty is statistical, the second is systematic, and the third is due to the uncertainty on the Bc+ lifetime. This is the first observation of a B meson decaying to another B meson via the weak interaction
