Recurrent Ischemic Stroke and Bleeding in Patients With Atrial Fibrillation Who Suffered an Acute Stroke While on Treatment With Nonvitamin K Antagon…
2022
Background: In patients with atrial fibrillation who suffered an ischemic stroke while on treatment with nonvitamin K antagonist oral anticoagulants, rates and determinants of recurrent ischemic events and major bleedings remain uncertain. Methods: This prospective multicenter observational study aimed to estimate the rates of ischemic and bleeding events and their determinants in the follow-up of consecutive patients with atrial fibrillation who suffered an acute cerebrovascular ischemic event while on nonvitamin K antagonist oral anticoagulant treatment. Afterwards, we compared the estimated risks of ischemic and bleeding events between the patients in whom anticoagulant therapy was chan…
Effect of heating of organo-montmorillonites under different atmospheres
2009
Abstract We studied the influence of heating on the behaviour of two organo-montmorillonites paying particular attention to the possible degradation effects of the organic modifier under different atmospheres. Hoffmann elimination and anucleophilic substitution on the nitrogen led to rapid degradation of the modifier. As confirmed by deconvoluted FTIR spectra, the presence of oxygen accelerated the degradation rate. The degradation products of the modifier (α-olefins transforming into various carboxyl compounds if oxygen is present) initially increased the basal spacing, followed by a collapse of the particle layers when the decomposition products migrated toward the surface and eventually …
Photo-stabilization of biopolymers-based nanocomposites with UV-modified layered silicates
2020
Abstract Eco-friendly in-situ stabilised biopolymer nanocomposites based on polyamide 11 (PA11) and polylactic acid (PLA) were prepared by melt mixing in the presence of a modified organo-montmorillonite clay containing a chemically-bound hindered amine UV-stabilising function, [(UV)OM-MMt]. Characterisation of the newly synthesised organo-modifier containing the reactive hindered amine (HAS) UV-stabilising function [(UV)OM] has confirmed a successful synthesis. The (UV)OM was then introduced into NaMMt through ion exchange reaction to prepare the UV stabiliser-bound organo-modified-MMt, [(UV)OM-MMt]. The in-situ stabilised PA11- and PLA- nanocomposites (PA11-(UV)OM-MMt and PLA-(UV)OM-MMt) …
Neue Aspekte der elektrischen Defibrillation
1998
In allen internationalen Empfehlungen stellt die schnellstmogliche Defibrillation die Masnahme der Wahl bei Kammerflimmern (VF) und pulsloser ventrikularer Tachykardie (VT) dar. Der Defibrillation kommt eine Schlusselrolle bei der Bekampfung des plotzlichen Herztodes zu. Technische Neuerungen: Entwicklungen auf technischem Gebiet haben einerseits eine weitere Miniaturisierung und Vereinfachung der Gerate, andererseits eine Anpassung der Energiemenge an die individuellen Patientenbedingungen zum Ziel. Implantierbare Kardioverter-Defibrillatoren (ICD) und automatisierte externe Defibrillatoren (AED) basieren auf der gleichen Technologie, einer gerateinternen Analyse des EKG-Signals mit nachfo…
Thermomechanical Characterization of Polylactic Acid and Composites
2018
This paper presents the experimental tests for the thermomechanical characterization of biopolymer polylactic acid, and its composites with beech flour or with nanoreiforcement of modified montmorillonite, in order to evaluate any applicability in the automotive sector. Tests of torque and traction are executed for the mechanical characterization and the results comparison; dynamical tests are executed for the thermomechanical characterization, determining the elastic modulus and loss factor versus the actual temperature.
Caratterizzazione termomeccanica dell’acido polilattico e due suoi compositi
2018
Questa memoria presenta i test sperimentali per la caratterizzazione termomeccanica del biopolimero acido polilattico e dei suoi compositi con farina di faggio o con nanorinforzo di montmorillonite modifcata, per uno studio di applicabilità nel settore automobilistico. Per la caratterizzazione meccanica e il confronto dei risultati vengono eseguiti prove di coppia e di trazione; i test dinamici vengono eseguiti per la caratterizzazione termomeccanica, determinando il modulo elastico e il fattore di perdita rispetto alla temperatura effettiva. This paper presents the experimental tests for the thermomechanical characterization of biopolymer polylactic acid, and its composites with beech flour…

[Atrial fibrillation in patients with COVID-19. Usefulness of the CHA
2021
Resumen Introduccion y objetivos La enfermedad por coronavirus de 2019 (COVID-19) esta causada por el segundo coronavirus del sindrome respiratorio agudo y grave. La fibrilacion auricular (FA) es comun en situaciones agudas, en las que conlleva mas complicaciones y mortalidad. Metodos Analisis del Registro internacional HOPE (NCT04334291); el objetivo es evaluar la informacion pronostica de FA en pacientes con COVID-19. Se realizo un analisis multivariable y un emparejamiento por puntuacion de propension para evaluar la relacion entre FA y mortalidad. Ademas, se evaluo en estos pacientes el impacto en la mortalidad y los eventos embolicos de la puntuacion CHA2DS2-VASc. Resultados Entre los …
Der pikareske Roman als Katalysator in geschichtlichen Abläufen : erzählerische Kommunikationsmodelle in Das Leben des Lazarillo von Tormes, bei Thom…
2005
Anna-Riitta Tunturi tutki väitöskirjassaan pikareski- eli veijariromaanin eri ilmenemismuotoja historiallisena läpileikkauksena, sosiologisena ilmiönä ja romaanitaiteen osa-alueena. Sana ”pícaro” tulee kastiliankielen verbistä ”picar”, joka tarkoittaa alempiarvoisten ammattien harjoittamista, kuten picador de toros, pikadori härkätaistelussa, toreadorin avustaja. Saksaksi sana on Schelm, joten oma sanamme kelmi on saksalaista lainaa. Lisäksi suomen kielessä on veijari, huijari, heittiö tai hulttio, ja lisääkin varmasti löytyy. This dissertation in comparative literature examines several Finnish picaresque novels of 20th century in relation to some classical continental European novels such …
