Nouvelles données biostratigraphiques sur les dépots cénomanoturoniens du Nord-Est du fosse de ia Bénoué (Nigéria)

1993

Abstract The Upper Cretaceous deposits of the Upper Benue (North-East Nigeria) record regional and local events (sea-level changes, biological successions and tectonic movements) which throw light on the Upper Cenomanian transgression. Evidence of discontinuities and sedimentary assemblages well dated by micropalaeontological data, allows the sedimentary sequence to be interpreted in the context of sequence stratigraphy. The discovery of new ammonite faunas has enabled a more precise definition of the local biostratigraphy and a correlation of this with the standard zonal scheme. In the near future, when they are better known, the ammonite successions recognized in the Upper Benue could ena…

On Combinatorial Generation of Prefix Normal Words

2014

A prefix normal word is a binary word with the property that no substring has more 1s than the prefix of the same length. This class of words is important in the context of binary jumbled pattern matching. In this paper we present an efficient algorithm for exhaustively listing the prefix normal words with a fixed length. The algorithm is based on the fact that the language of prefix normal words is a bubble language, a class of binary languages with the property that, for any word w in the language, exchanging the first occurrence of 01 by 10 in w results in another word in the language. We prove that each prefix normal word is produced in O(n) amortized time, and conjecture, based on expe…

Concanavalin A aggregation and toxicity on cell cultures

2009

A number of neurodegenerative diseases are known to involve protein aggregation. Common mechanisms and structural properties of amyloids are thought to be involved in aggregation-related cytotoxicity. In this context we propose an experimental study on Concanavalin A (Con A) aggregation and use it as a model to study the relationship between cell toxicity and aggregation processes. Depending on solution conditions, Con A aggregation has been monitored by static and dynamic light scattering, Thioflavin T emission, and FTIR absorption. The morphology of different aggregate species was verified by means of Atomic Force Microscopy and Confocal Microscopy. During the aggregation pathway the nati…

The popularization of plate tectonics: presenting the concepts of dynamics and time

1996

There have been many attempts to describe and represent the theory of plate tectonics to laypeople. In the context of a study conducted at the request of a museum, we have tried to determine how the concepts of both geological time and the movements of the plates have been reformulated. After having systematically studied in detail publications aimed at more or less educated readers, we have selected a corpus of twelve articles from nine different magazines or journals. Among the different means of expression used by the popularizers, rhetorical figures constitute a significant resource. Procedures based on analogy (metaphor, comparison, analogical reasoning) were brought together in a sing…

First signals of electrochemically oxidized species of TTF and TMT-TTF : a study by in situ spectroelectrochemical FTIR and DFT calculations

2003

A first study by in situ FTIR spectroelectrochemistry of TTF and TTM-TTF has been undertaken. The oxidation, in this case, is caused only by electrochemistry, which constitutes a clear advantage over chemical oxidation since no side products are present in the solution. In this context, we obtained the signals of neutral, radical cation, and dication species of TTF and TTM-TTF. The experimental conditions were chosen in order to avoid the possible formation of π-dimer species and to obtain a satisfactory signal-to-noise ratio. A weak signal was detected for TTF and a stronger one for TTM-TTF. The changes induced by the oxidation process in the IR spectra of TTF and TTM-TTF have been analyze…

New quality regulations versus established nursing home practice: a qualitative study

2012

Published version of an article from the journal: BMC Nursing. Also available from Bio Med Central:http://dx.doi.org/10.1186/1472-6955-11-7 Open Access Background Western governments have initiated reforms to improve the quality of care for nursing home residents. Most of these reforms encompass the use of regulations and national quality indicators. In the Norwegian context, these regulations comprise two pages of text that are easy to read and understand. They focus particularly on residents’ rights to plan their day-to-day life in nursing homes. However, the research literature indicates that the implementation of the new regulations, particularly if they aim to change nursing practice, …

Teaching Physical Education in English using CLIL Methodology: A Critical Perspective

2015

Abstract Relatively little research has been carried out in Europe on teaching Physical Education (PE) in English as a Lingua Franca (ELF) using the CLIL method. Although CLIL is widely used throughout Europe, the PE content is often limited merely to technical-practical skills without any significant links to a socio-cultural context, critical thinking and/or knowledge acquisition. The aim of this study is to integrate CLIL with the epistemological perspective of critical pedagogy applied to physical education (Kirk, 2014). A theoretical “deconstructive” method will be used to provide guidelines for teaching physical education through CLIL. A cultural content based on language, culture and…

Animal agency in Iron-Age Sicilian art (VIII-VI BCE): Interaccion between bovines and man

2019

El objetivo del presente artículo es el análisis de las relaciones entre bovinos y humanos bajo la perspectiva de la agencia animal a través de varios objetos artísticos encontrados en el asentamiento de Polizzello (Sicilia occidental), datados entre los ss. VIII-VI a. C. Concretamente, presentamos un conjunto de jarras cerámicas decoradas con bucráneos, así como también representaciones de bovinos y seres híbridos en distintos soportes cerámicos como son vasos de almacenamiento, de consumo y servicio de alimentos. En primer lugar, nos centraremos brevemente en explicar el contexto histórico y social de la isla en la Edad del Hierro, haciendo especial énfasis en sus tradiciones artísticas. …
