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…
Ethidium bromide: a fast fluorescent staining procedure for the detection of symbiotic partnership of flagellates and prokaryotes
1999
The hindgut of 'lower' termites harbors a dense population of flagellates and bacteria. The flagellates possess ecto- and endosymbiotic prokaryotes. Most of them are hardly visible in the phase contrast microscope. Staining with the DNA-intercalating agent ethidium bromide visualizes the nuclei of the flagellates as well as the ecto- and endosymbiotic bacteria as red objects. Furthermore, it is possible to distinguish between endosymbiotic methanogens and other bacteria. Following UV excitation, the blue-green autofluorescence of the methanogenic bacteria eclipses the red fluorescence light of the intercalated ethidium bromide. The dye facilitates the observation of symbiotic bacteria and h…
Soldier formation regulated by a primer pheromone from the soldier frontal gland in a higher termite, Nasutitermes lujae
1984
In the nasute higher termite Nasutitermes lujae , the differentiation of new soldiers is suppressed or delayed by the soldiers themselves. Experimental data strongly suggest that this inhibitory effect results from the action of a primer pheromone secreted by the frontal gland of soldiers. The pheromone must be contacted directly. Thus, the frontal gland of termite soldiers assumes a new role in addition to alarm and defense, although this extension cannot be generalized to all termite species. The soldier inhibitory pheromone is evidently only one of multiple factors contributing soldier regulation in termite societies.
Replacement queens in the neotropical termiteNasutitermes coxipoensis
1987
The production of replacement queens in experimentally orphaned colonies was investigated in the neotropical termiteNasutitermes coxipoensis holmgren. A single adultoid replacement queen was produced with six weeks in more than 50% of the nests. The new queen begins oviposition extremely quickly. Replacement kings are seldom seen but must be present since brood in the nest in atribuable to the replacement queen. InN. coxipoensis, replacement adultoid queens and kings seem to develop preferentially from the few aged nymphs which are present in the nest throughout the year.
Neology and lemmatization: clippings and acronyms in spanish dictionaries
2020
espanolEsta investigacion presenta tres objetivos: describir el tratamiento lexicografico de los acortamientos y siglas en diccionarios actuales del espanol; caracterizar las nuevas unidades lexicas formadas por reduccion en cotextos de uso reales (periodisticos y digitales); y disenar una propuesta de criterios para integrar de un modo coherente estas unidades en los diccionarios. Para alcanzar estos objetivos, en primer lugar se describen los acortamientos y siglas detectados en la nomenclatura del DLE (2017) y en el vaciado de dos repertorios de neologismos (Neologismos del espanol actual y Corpus Obneo) y del Corpus del espanol. En segundo lugar, a partir de estos datos, se configura un…
Comparative Genomics of Blattabacterium cuenoti: The Frozen Legacy of an Ancient Endosymbiont Genome
2013
Many insect species have established long-term symbiotic relationships with intracellular bacteria. Symbiosis with bacteria has provided insects with novel ecological capabilities, which have allowed them colonize previously unexplored niches. Despite its importance to the understanding of the emergence of biological complexity, the evolution of symbiotic relationships remains hitherto a mystery in evolutionary biology. In this study, we contribute to the investigation of the evolutionary leaps enabled by mutualistic symbioses by sequencing the genome of Blattabacterium cuenoti, primary endosymbiont of the omnivorous cockroach Blatta orientalis, and one of the most ancient symbiotic associa…
Brief an Garlieb H. Merkel
1799
Ms. 930a, Nr. 8, Bl. 22r-23v Böttiger, Karl August. Brief an Garlieb H. Merkel, Weimar, d[en] 13. November 1797 Autora rokraksts / Autograph, vācu, angļu un latīņu val. / Deutsch, Englisch und Latein [4] lpp. / S. Attēlu numuri / Bildnummern: 930a-008-1 – 930a-008-4 Der Verfasser nennt in diesem inhaltsreichen Brief zahlreiche Namen und hält nicht nur die Verbindung mit Merkel, die aus dessen erstem Aufenthalt in Weimar resultierte, aufrecht, sondern gibt ihm weitere Hinweise und Empfehlung für seinen weiteren Aufenthalt in Dänemark. So rät er zur Übersetzung dreier Romane aus dem Englischen, darunter Jane Wests „A gossip's story“ (London 1796). Ferner bittet der Verfasser Merkel um Gefälli…
“Phraseological fossils”: morphology of "fossil words" as idiomatic words in Spanish idioms
2020
[ES] En el presente trabajo pretendemos ofrecer un análisis de la configuración formal del tipo de palabras idiomáticas que denominamos “fósiles fraseológicos”. Para ello, tras delimitar los conceptos de “palabra idiomática” y “fósil fraseológico”, se aclaran los procedimientos metodológicos para recopilar este tipo de voces en un diccionario general actual como el DLE, y se procede al análisis del corpus obtenido. El principal rasgo de los fósiles fraseológicos es que presentan los cambios evolutivos característicos de la evolución del latín al español, como voces patrimoniales que son. [EN] The objective of this paper is to offer an analysis of the morphology of the kind of idiomatic word…
(+)-α-Pinene in the defensive secretion ofNasutitermes princeps (Isoptera, Termitidae)
1990
The frontal secretion ofNasutitermes princeps consists of 89% diterpenes and 11% monoterpenes. In the samples studied, (+)-α-pinene, whose optical purity reaches 99.5%, accounts for more than 80% of the monoterpenic content.
Analisi della comunità microbica intestinale di Reticulitermes lucifugus (Rossi) (Isoptera: Rhinotermitidae).
2009
L’intestino delle termiti ospita una comunità microbica di batteri e flagellati anaerobi, responsabile della degradazione del materiale lignocellulosico. La digestione della lignocellulosa da parte delle termiti dipende dalla simbiosi con microrganismi procarioti ed eucarioti che vivono nel loro intestino. I microrganismi trasformano la cellulosa in zuccheri e acetato, producendo idrogeno, metano e anidride carbonica. Abbiamo analizzato la comunità microbica intestinale di Reticulitermes lucifugus lucifugus, una delle due specie di termiti italiane, che vive in ambienti sotterranei, è distruttiva per le strutture legnose degli ambienti urbani causando seri danni ai monumenti storici e può c…
