Antyfilozofia cynicka w Nigrinosie Lukiana
2013
Cynics in their pursuit of “defacing the coinage” did not content themselves with critique of culture from philosophical point of view, but turned warrant given by Apollon against philosophy itself. Th e root of cynical anti-philosophy was antiintelectualism and antiplatonism of Anthisthenes and his early followers. Lucian’s Nigrinos is a fine example of late cynical anti-philosophy. Author unfolds before reader panorama of 2nd century Athens, where philosophy is a widely accepted form of life and the object of communal education. Both satirical description of the city of philosophers and the quasi-religious conversion of the main speaker provide a comprehensive view of philosophy as an irr…
Nitric oxide synthase 2 (NOS2) expression in histologically normal margins of oral squamous cell carcinoma
2014
The activity of Nitric Oxide Synthase 2 (NOS2) was found in oral squamous cell carcinomas (OSCC) but not in normal mucosa. Molecular changes associated to early carcinogenesis have been found in mucosa near carcinomas, which is considered a model to study field cancerization. The aim of the present study is to analyze NOS2 expression at the histologically normal margins of OSCC. Study Design: Eleven biopsy specimens of OSCC containing histologically normal margins (HNM) were analyzed. Ten biopsies of normal oral mucosa were used as controls. The activity of NOS2 was determined by immunohistochemistry. Salivary nitrate and nitrite as well as tobacco and alcohol consumption were also analyzed…
Oral cancer risk and molecular markers
2004
El aspecto clínico y en especial el grado de displasia que pueden presentar las lesiones precancerosas de la cavidad oral sugieren su capacidad potencial de malignización. Cada vez es más frecuente encontrar investigaciones orientadas hacia la búsqueda de nuevos marcadores, más específicos, que contribuyan a determinar el grado de alteración celular y permitan una mayor aproximación al conocimiento del grado de degeneración maligna de aquellas lesiones. En el presente trabajo de revisión se repasan los conceptos más actuales de estos marcadores, agrupados por familias: marcadores de crecimiento tumoral; marcadores de supresión tumoral y de respuesta antitumoral; marcadores de angiogénesis; …
Collectivity along N=50: Nuclear Structure studies on the neutron-magic nuclei 92Mo and 94Ru with AGATA and VAMOS++
2019
El trabajo desarrollado en esta Tesis se centra en estudio experimental del comportamiento colectivo de los estados excitados de los núcleos semimágicos con N=50 en función de la ocupación del orbital g9/2 de protones, a través de la medida de la vida media de los estados "yrast" 4+ de los núcleos 92Mo y 94Ru. En particular, se ha investigado la conservación de "seniority" a lo largo de la capa g9/2 que es la primera capa donde podría no conservarse. El 100Sn, siendo el núcleo doblemente mágico ligado más pesado con igual número de protones y neutrones, ha atraído siempre un considerable interés desde el punto de vista experimental y teórico. La estructura de este núcleo y sus vecinos son e…
Taxas de substituições das Annonaceas: uma perspectiva do modelo códon
2014
The Annonaceae includes cultivated species of economic interest and represents an important source of information for better understanding the evolution of tropical rainforests. In phylogenetic analyses of DNA sequence data that are used to address evolutionary questions, it is imperative to use appropriate statistical models. Annonaceae are cases in point: Two sister clades, the subfamilies Annonoideae and Malmeoideae, contain the majority of Annonaceae species diversity. The Annonoideae generally show a greater degree of sequence divergence compared to the Malmeoideae, resulting in stark differences in branch lengths in phylogenetic trees. Uncertainty in how to interpret and analyse these…
Evidence of octupole-phonons at high spin in 207Pb
2019
A lifetime measurement of the 19/2 state in Pb has been performed using the Recoil Distance Doppler-Shift (RDDS) method. The nuclei of interest were produced in multi-nucleon transfer reactions induced by a Pb beam impinging on a Mo enriched target. The beam-like nuclei were detected and identified in terms of their atomic mass number in the VAMOS++ spectrometer while the prompt γ rays were detected by the AGATA tracking array. The measured large reduced transition probability B(E3,19/2→13/2)=40(8) W.u. is the first indication of the octupole phonon at high spin in Pb. An analysis in terms of a particle-octupole-vibration coupling model indicates that the measured B(E3) value in Pb is compa…
Conceptual design of the AGATA 1$\pi$ array at GANIL
2017
The Advanced GAmma Tracking Array (AGATA) has been installed at the GANIL facility, Caen-France. This setup exploits the stable and radioactive heavy-ions beams delivered by the cyclotron accelerator complex of GANIL. Additionally, it benefits from a large palette of ancillary detectors and spectrometers to address in-beam γ-ray spectroscopy of exotic nuclei. The set-up has been designed to couple AGATA with a magnetic spectrometer, charged-particle and neutron detectors, scintillators for the detection of high-energy γ rays and other devices such as a plunger to measure nuclear lifetimes. In this paper, the design and the mechanical characteristics of the set-up are described. Based on sim…

Mecanismos de atenuación entre el decir y lo dicho: procesos de enunciación a través de la partícula discursiva digamos
2018
Este trabajo presenta los resultados obtenidos en el análisis de la partícula discursiva digamos en corpus coloquiales (Val.Es.Co. 2002 y 2.0.), aplicando el sistema de unidades, niveles y posiciones Val.Es.Co. (Briz y grupo Val.Es.Co. 2003, 2014) y la ficha Es. Por. Atenuación (Albelda et alii 2014). El resultado integra dos perspectivas de análisis para determinar si factores como la unidad ocupada o posición discursiva condicionan su polifuncionalidad. This study presents the results obtained from the analysis of the Spanish discourse particle digamos in colloquial corpus. The Val.Es.Co. proposal (Briz et alii 2003, 2014) and the Es.Var.Atenuación analysis sheet (Albelda et alii 2014) ar…
Flowers, Water accumulation and Corporate Social Responsibility: Certification of the Production of Roses and Claims for Environmental Justice in Ecu…
2018
La producción comercial de flores, el acaparamiento del agua y las luchas sociales por un reparto equitativo y un ambiente sano tienen una estrecha relación. Ecuador es el tercer exportador mundial de rosas. Cayambe-Tabacundo es la principal zona de producción y presenta una fuerte presión sobre los recursos hídricos. El agua es acaparada por las grandes empresas florícolas, quedando el resto para agricultura/ganadería de subsistencia en comunidades indígenas. Las florícolas utilizan las certificaciones ambientales y de comercio justo privadas, pero los estándares son permisivos. Este artículo analiza las relaciones de poder detrás de las prácticas de certificación de flores. Concluye que s…
