Estudo Comparativo da Infiltração Apical entre Dois Cimentos Endodônticos
2009
ResumoO objectivo deste estudo é comparar a capacidade de selamento apical de dois cimentos endodônticos. Foram utilizados trinta e oito dentes monorradiculares e divididos em dois grupos de 15 elementos, de acordo com o cimento utilizado (Grupo A: AH Plus e Grupo B: Tubli-Seal). Foram utilizados oito dentes nos grupos controlo positivo e negativo que não foram obturados (Grupo C). Os canais foram instrumentados pela técnica de crown-down, utilizando as limas Hero Shaper® and Hero 642® (Micro-Mega S.A., Besançon, France) e irrigados com hipoclorito de sódio a 5,25% entre cada instrumento. O smear layer foi removido utilizando 3ml de EDTA a 17% no final da instrumentação durante 3 minutos, s…
Level structure of 99Nb
1998
The β decay of 97Sr to 97Y has been investigated using ion-guide on-line mass separation and a 10 Ge-detector array to record γ−γ coincidences to a detection limit well below that of former studies. Similarities are found in the β-decay patterns of 99Zr and of its isotone 97Sr and also in the γ-ray decay rates and branchings of the corresponding levels in their respective daughters 99Nb and 97Y. This indicates a persisting influence of the d5/2 neutron shell closure for 99Nb. The level structure of 99Nb and the β-feeding pattern are discussed in the frame of the interacting boson-fermion plus broken pair model and the microscopic quasiparticle phonon model.
A novel arousal-based individual screening reveals susceptibility and resilience to PTSD-like phenotypes in mice
2021
Translational animal models for studying post-traumatic stress disorder (PTSD) are valuable for elucidating the poorly understood neurobiology of this neuropsychiatric disorder. These models should encompass crucial features, including persistence of PTSD-like phenotypes triggered after exposure to a single traumatic event, trauma susceptibility/resilience and predictive validity. Here we propose a novel arousal-based individual screening (AIS) model that recapitulates all these features. The AIS model was designed by coupling the traumatization (24 h restraint) of C57BL/6 J mice with a novel individual screening. This screening consists of z-normalization of post-trauma changes in startle …

Learning to Teach Mathematics: Expanding the Role of Practicum as an Integrated Part of a Teacher Education Programme
2009
The premise of the 15th ICMI Study is that teachers are key to students' opportunities to learn mathematics. What teachers of mathematics know, care about, and do is a product of their experiences and socialization, together with the impact of their professional education. The Professional Education and Development of Teachers of Mathematics assembles important new international work- development, research, theory and practice - concerning the professional education of teachers of mathematics. As it examines critical areas to reveal what is known and what significant questions and problems warrant collective attention, the volume also contributes to the strengthening of the international co…
Explotación de la tierra y tipos de mercado en la agricultura de la España contemporánea. Un comentario
1992
Se hace un repaso a los materiales presentados para el debate de la circulación del excedente en la España rural contemporánea. El debate se centró en las relaciones de propiedad y formas de tenencia de la tierra, la caracterización de los mercados agrarios y configuración de estrategias de participación en los mismos, y en las formas de gestión de las explotaciones. En las ponencias se destacó la intensa y diversa participación de los agentes sociales en los mercados de factores y los cambios en las formas de tenencia y explotación de la tierra como "estrategia" de adaptación de los propietarios a las diferentes coyunturas agrarias. The various points presented for the discussion over the …
A phase II study of carboplatin and paclitaxel as first line chemotherapy in elderly patients with advanced non-small cell lung cancer (NSCLC)
2006
Introduction: Lung cancer is the leading cause of tumour-related deaths in the elderly population but the optimal management of advanced NSCLC in older patients has not been defined to date. The present phase II study was planned to evaluate the efficacy and toxicity of the combination of carboplatin and paclitaxel in elderly patients with advanced NSCLC. Patients and methods: Patients (>70 years old) who had pathologically been proven to have a NSCLC and measurable lesions were treated with paclitaxel (175 mg/m2for 3 h) and carboplatin [area under the concentration-time curve (AUC = 5)] on day 1 every 3 weeks. Results: Forty patients were enrolled into the study. The median age was 74 year…
EPPS16: Nuclear parton distributions with LHC data
2017
We introduce a global analysis of collinearly factorized nuclear parton distribution functions (PDFs) including, for the first time, data constraints from LHC proton-lead collisions. In comparison to our previous analysis, EPS09, where data only from charged-lepton-nucleus deep inelastic scattering (DIS), Drell-Yan (DY) dilepton production in proton-nucleus collisions and inclusive pion production in deuteron-nucleus collisions were the input, we now increase the variety of data constraints to cover also neutrino-nucleus DIS and low-mass DY production in pion-nucleus collisions. The new LHC data significantly extend the kinematic reach of the data constraints. We now allow much more freedom…
Are decisions in a real choice experiment consistent with reservation prices elicited with BDM 'auction'? The case of French baguettes
2014
Abstract The aim of this study was to compare consumer choices observed in a real choice experiment and their reservation prices elicited with the BDM mechanism in order to assess the rationality of participant behaviors. One hundred and seventy-seven participants tested four French baguettes in each task. For the real choice experiment, participants were faced with 17 scenarios (17 × 4 baguette-price combinations). In each method, participants could select a “no purchase” option. Comparing choices and reservation prices made it possible to assess the rationality of participant behaviors. From a strict economic standpoint, 50% of observed choices were fully rational. When one baguette was a…
Rafael l. Ninyoles: Recorregut biogràfic i intel·lectual
2020
This article presents the biography and intellectual legacy of Valencian sociologist Rafael L. Ninyoles (1943- 2019). It reviews his formative itinerary, his early contributions to the field of the sociology of language, his latest contributions to the sociology of cities and cultural spaces, and his key involvement in the promoti-on and consolidation of the sociological study of Valencian society. The article includes a note on public acknowledgements to the author, plus an annex with a selective bibliography aimed at serving the interested reader and the posthumous diffusion of Ninyoles? oeuvre.
