La partícula alemana und zwar: ¿conjunción, adverbio, conector, marcador del discurso?
2022
Este trabajo revisa el tratamiento de la partícula 'und zwar' en la gramática teórica reciente y los intentos de clasificarla dentro del sistema de categorías de la lengua alemana. Para ello, se parte de su consideración como unidad con significado procedimental vinculada a los procesos de construcción textual y organización de la información. El análisis de 271 muestras de 'und zwar' extraídas de un corpus de monólogos parlamentarios ha permitido fijar los rasgos que caracterizan el uso de esta unidad en este género discursivo, que se refieren a su forma, significado, distribución sintáctica y funciones pragmático-discursivas. Los datos obtenidos sugieren la consideración de 'und zwar' com…
Ortotipografía científica en publicaciones médico-quirúrgicas: la normativa académica relativa a la prefijación
2015
El objetivo del presente artículo es analizar el grado de cumplimiento de la normativa académica relativa a la correcta escritura de las palabras prefijadas (recogida en la nueva Ortografía de 2010) que realizan algunas publicaciones periódicas de carácter científico-técnico y, en concreto, del ámbito médico-quirúrgico. Se trata de una labor de profundización en un estudio anterior (Aguilar Ruiz 2012: 9-12). Para ello, comentamos los errores e incorrecciones más recurrentes de un corpus de publicaciones científicas argentinas de finales de 2012. The aim of this paper is to analyze the degree of compliance on the correct academic writing prefixed words (contained in the new spelling) that pe…
The Polysemy of the verbs «pegar», «apegar» and «empegar» in Catalan : a synchronic manifestation of semantic change
2015
In this paper we study the polysemy that the verbs pegar ('hit/stick'), apegar ('stick') and empegar ('stick') possess today in the Catalan language. First of all, we perform a thorough description of the meanings that each of these verbs have acquired not only in the standard but also in the colloquial language. Each of the meanings has been differentiated from the others by analysing the most prominent dictionaries currently available and a corpus of written texts. Additionally, a number of surveys on the spoken language have also been taken into account. Our research has shown that in the different Catalan dialects they do not always have the same meanings or the same verb forms. To be a…
La llengua catalana en la literatura de viatges del primer terç del vuit-cents
2022
Aquest treball analitza les descripcions de la llengua catalana que feren els viatgers que van recórrer els Països Catalans i, especialment, el País Valencià al llarg del primer terç del segle XIX. Alhora, examina les observacions i les percepcions lingüístiques d'aquests viatgers sobre la llengua catalana, i especialment sobre la seva unitat/diversitat interna, la seva catalogació entre la resta de les llengües romàniques i l'ús d'aquesta per part dels habitants d'aquests territoris. Les obres que s'hi estudien no són només llibres de viatges, sinó també aquells textos informatius que servien als viatgers per a orientar i contextualitzar els seus itineraris: guies de viatge i obres de topo…
El cambio semántico del verbo pegar en catalán (siglos XIII-XXI)
2016
This article studies the polysemy of the verb pegar from a diachronic perspective. The study is based on research conducted on an extensive corpus of texts written between the 13th and 21st centuries, as well as on the information provided by different historical dictionaries. The author identifies the different meanings acquired by the verb pegar by documenting and dating them. The analysis shows that the meanings that are most directly related with the etymological sense of sticking gradually become obsolete. In contrast, new meanings connected with them are generated, one of the most important being the sense of 'to touch with a certain amount of violence or intensity, to hit'. The inter…
Production of methyl mercury in the gut of the Australian termite Mastotermes darwiniensis
2008
Animals are often exposed to or can ingest heavy metals along with their food. Therefore, we tested whether the hindgut microbiota of Mastotermes darwiniensis possesses the capability to form methyl mercury. The termite M. darwiniensis (Isoptera) was fed with saw dust containing different concentrations of inorganic mercury. Methyl mercury was determined by purge-and-trap capillary gas chromatography-atom fluorescence spectrometry (CGC-AFS) using ethyl mercury chloride as the internal standard. Total mercury concentrations were determined in the termite tissue by inductive coupled plasma-isotope dilution mass spectrometry (ICP-IDMS) after microwave-assisted digestion. The obtained results s…
Co-expression of CD133+/CD44+in human colon cancer and liver metastasis
2013
Although relatively good therapeutic results are achieved in non-advanced cancer, the prognosis of the advanced colon cancer still remains poor, dependent on local or distant recurrence of the disease. One of the factors responsible for recurrence is supposed to be cancer stem cells (CSCs) or tumor-initiating cells, which are a population of cancer cells with ability to perpetuate themselves through self-renewal and to generate differentiated cells, thought to be responsible for tumor recurrence. This study globally approach the possible role of tissue-derived stem cells in the initiation of colon cancer and its metastatic process in the liver. Fresh surgical specimens from colon cancer, no…
Ultrastructure and formation of the physogastric termite queen cuticle
1982
0040-8166 (Print) Journal Article; The physogastric termite queen is the most striking example in insects of growth in size without cuticular moulting. This phenomenon has been studied with electron microscopy and histochemical tests in two species of higher termites, Cubitermes fungifaber and Macrotermes bellicosus. The abdominal hypertrophy (physogastry) is allowed by growth of the arthrodial membranes of the swarming imago. The growth is slow (over several years) but important: the cuticular dry weight is multiplied by 20 in C. fungifaber, by 100-150 in M. bellicosus. The termite queen cuticle arises from the transformation of the cuticle of the swarming imago or imaginal cuticle (unfold…
A new species of Charinus Simon, 1892 (Amblypygi, Charinidae) from termite nests in French Guiana
2015
The genus Charinus is represented by 51 species, distributed in all tropical regions. Their small size allows them to use a wide range of micro-habitats, from caves, litter to insect nests. The new species C. sillami sp. nov. was found into termite nests of three different species: Neocapritermes taracua, Spinitermes sp. and Embiratermes neotenicus. Only Paracharon caecus (Paleoamblypygi: Paracharontidae) was previously known to be associated with Isoptera. Eleven species of Charinus were previously known from Northern South America. Charinus sillami sp. nov. is the second species of the genus occurring in French Guiana. An updated key of Northern South-American species is provided.
Estratègies discursives iròniques en la narrativa catalana actual: l'autoconsciència textual
2010
A partir de textos de Jesús Moncada, Quim Monzó, Carme Riera, Ramon Solsona i Sergi Pàmies, l'article analitza l'existència en la narrativa breu catalana actual d'una tendència que es caracteritza per l'ús dels recursos de la metaficció, adaptats als interessos literaris i a l'estil de cada autor però amb una orientación general compartida. Es tracta d'una tendència de clar signe antirealista i amb plena consciència de textualitat que fa explícits els mecanismes de la ficció; una modalitat de discurs irònic que s'interroga sobre les possibilitats i els límits de representació del real i, en definitiva, sobre allò que entenem per realitat. Departing from some texts by Jesús Moncada, Quim Mon…
