La actuación de los subinspectores de empleo y Seguridad Social (caso práctico)

El presente caso práctico reproduce el enunciado del supuesto planteado como tercer ejercicio en la convocatoria de la Oposición para el ingreso en el Cuerpo de Subinspectores de Empleo y Seguridad Social correspondiente a 2007 (Orden TAS/919/2007, de 27 de marzo). En él se efectúa un análisis de las cuestiones derivadas del planteamiento, incorporando la fundamentación jurídica de la respuesta

Experimental study of cardiac innervation in the cat after right stellectomy

En el presente trabajo se estudia, mediante degeneración walleriana y con tinciones argénticas de Gros, la distribución de la inervación simpática en las distintas áreas del corazón del gato (Felis silvestris catus), tras realizar simpatectomías derechas (estelectomías). Estas intervenciones se realizaron por vía anterior hasta llegar al ganglio estrellado. Tras analizar el material encontramos fibras nerviosas mielínicas degeneradas en: el área del pedículo arterial, en la zona de desembocadura de la vena cava superior y en las redes perivasculares del tabique interauricular de la aurícula derecha y del ventrículo derecho, y, en menor cantidad, encontramos, fibras degeneradas, en la zona del seno coronario, tabique interventricular y aurícula y ventrículo izquierdo.In the present study, Wallerian degeneration and Gros silver staining were used to investigate the distribution of sympathetic innervation in different areas of the heart of cat (Felis silvestris catus) after performing right sympathectomy (stellectomy). An anterior surgical approach was used to reach the stellate ganglion. Analysis of the material revealed degenerated myelin nerve fibres in artery pedicle area, area of the opening of the vena cava superior, and perivascular networks of the interatrial wall of the right atrium and right ventricle and showed, in smaller amounts, degenerated fibres in the coronary sinus area, ventricular and atrial wall and left ventricle

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
