Maduración pre-inducción de parto. Comparación entre dinoprostona y misoprostol con objetivación de dinámica uterina mediante electrohisterografía: U…
2019
La inducción del parto y la maduración cervical son temas de gran interés dentro de la obstetricia, llegando a alcanzar el 30% del total de nacimientos. Además, su inadecuada indicación conlleva una iatrogenia considerable respecto a los resultados neonatales, el aumento de la tasa de cesáreas y los costes. Si bien disponemos de muchos métodos con una efectividad y seguridad contrastada, la investigación en busca del método óptimo para la maduración cervical en cuellos uterinos desfavorables continúa en marcha. Actualmente las prostaglandinas Dinoprostona y Misoprostol son los agentes maduradores de primera elección en nuestro medio. Entre los diferentes estudios publicados, existe heteroge…

Orbital angular momentum parton distributions in quark models
1999
At the low energy, {\sl hadronic}, scale we calculate Orbital Angular Momentum (OAM) twist-two parton distributions for the relativistic MIT bag model and for non-relativistic quark models. We reach the scale of the data by leading order evolution in perturbative QCD. We confirm that the contribution of quarks and gluons OAM to the nucleon spin grows with $Q^2$, and it can be relevant at the experimental scale, even if it is negligible at the hadronic scale, irrespective of the model used. The sign and shape of the quark OAM distribution at high $Q^2$ may depend strongly on the relative size of the OAM and spin distributions at the hadronic scale. Sizeable quark OAM distributions at the had…
Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV
2021
Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…
Charged jet cross sections and properties in proton-proton collisions at $\sqrt{s}=7$ TeV
2015
The differential charged jet cross sections, jet fragmentation distributions, and jet shapes are measured in minimum bias proton-proton collisions at centre-of-mass energy $\sqrt{s}=7$ TeV using the ALICE detector at the LHC. Jets are reconstructed from charged particle momenta in the mid-rapidity region using the sequential recombination $k_{\rm T}$ and anti-$k_{\rm T}$ as well as the SISCone jet finding algorithms with several resolution parameters in the range $R=0.2$ to $0.6$. Differential jet production cross sections measured with the three jet finders are in agreement in the transverse momentum ($p_{\rm T}$) interval $20<p_{\rm T}^{\rm jet,ch}<100$ GeV/$c$. They are also consistent w…
Satisfacción de la mujer con los cuidados de salud recibidos durante el parto prematuro: adaptación y validación al castellano de la Preterm Birth Ex…
2020
Introducción Todas las mujeres tienen derecho a recibir una atención sanitaria de excelencia. Conocer la satisfacción maternal con los cuidados de salud recibidos durante el parto es un aspecto de gran relevancia para las madres, profesionales y gestores sanitarios, siendo un indicador de calidad asistencial. Existe una amplia variedad de instrumentos para medir la satisfacción maternal. Sin embargo, muchos difieren en contenido y calidad metodológica, evidenciando una dudosa utilidad, y la mayoría están dirigidos a mujeres sanas con embarazos de bajo riesgo obstétrico, ignorando la satisfacción en mujeres con bebés prematuros. Objetivos El objetivo general es analizar la satisfacción de la…
Search for scalar leptoquarks in pp collisions at $\sqrt{s}$=13 TeV with the ATLAS experiment
2016
An inclusive search for a new-physics signature of lepton-jet resonances has been performed by the ATLAS experiment. Scalar leptoquarks, pair-produced in pp collisions at s √s = 13 TeV at the large hadron collider, have been considered. An integrated luminosity of 3.2 fb-1, corresponding to the full 2015 dataset was used. First (second) generation leptoquarks were sought in events with two electrons (muons) and two or more jets. The observed event yield in each channel is consistent with Standard Model background expectations. The observed (expected) lower limits on the leptoquark mass at 95% confidence level are 1100 and 1050 GeV (1160 and 1040 GeV) for first and second generation leptoqua…
