¿Es Necesario un Nuevo Nombre para el Bibliotecario?

A pesar de que conservamos el nombre arcaico, ligado a la concepción del libro y de la biblioteca como depósito de libros, frente a un acelerado desarrollo que involucro tecnologías y materiales digitales en el manejo de información, es un hecho que en las últimas décadas el prestigio del bibliotecario como erudito y especialista ha cambiado por el de ser un buscador y un proveedor ágil y especializado en la amplia gama de recursos informativos que nos rodea.La tendencia más seguida es que la profesión debe cambiar pasando a enfatizar otras habilidades como la gerencia, puesto que las bibliotecas serán evaluadas por los servicios que ofrecen y no tanto por los acervos que poseen. Sin embargo, que las bibliotecas como tal persisten es un hecho que se comprueba con la famosa Biblioteca de París, que está diseñada en forma de libro precisamente.

Los jardines "pintados" de Émile Zola, lugares de encuentro entre literatura y arte

The thesis here presented, entitled “PAINTED” GARDENS BY ÉMILE ZOLA, MEETING PLACES OF LITERATURE AND ART, aims to analyze the treatment of the theme of garden in La Curée, the second of the twenty novels that make up the cycle of Les Rougon-Macquart, series published between 1871 and 1893. In this story, the author, an ardent republican, bluntly attacks the imperial regime, emphasizing the confusion of high society, the immorality of speculation occurred under the Haussmann's renovation of Paris, the profusion of luxury and pleasure, and, in short, a dynamism geared exclusively to the sense of destruction or perversion. Hence we have devoted an entire chapter to argue the presentation of this novel as a chronicle of Parisian society of the Second Empire. Also, because reading Zola is to recognize the profusion of metaphorical language, the analysis of the poetic discourse has played an important role in the body of this thesis. This analysis focuses on the two major descriptions of the greenhouse of hôtel Saccard, in chapters I and IV, both aiming to present this garden as a disturbing space, favorable to the discovery of unsuspected amorous capabilities, according to the mentality of the nineteenth century, so full of puritan principles, for which the tropical world of greenhouses meant a sexual freedom which did not understand bans or limitations. The sexual corruption that occurs in this greenhouse, is not only indicative of moral laxity in personal relationships, but also works as a symbolic image of decay and breakdown of society as a whole...

La noblesse montréalaise devant les tribunaux (1750-1793)

Entre la fin du régime français et l’adoption de l’Acte constitutionnel par le Parlement de Londres en 1791, le rapport que la noblesse canadienne entretient avec le système judiciaire civil de la colonie change de façon majeure. Les Canadiens doivent s’adapter au nouveau système mis en place par l’administration britannique de la colonie. En Nouvelle-France, les nobles présentaient leurs différends juridiques civils devant le Tribunal royal, régi par la Coutume de Paris ; à partir de la Cession (1763), ce sont officiellement les lois britanniques qui s’appliquent jusqu’au retour des lois civiles françaises en 1774. Après quelques adaptations, la Cour des Plaidoyers communs devient la cour de prédilection des Canadiens, et par conséquent, de l’ancienne élite militaire. Le système judiciaire constitue un élément important de l’étude de l’évolution de la colonie, car l’attitude de la caste élitaire face aux tribunaux est un indicateur de sa capacité d’adaptation et de son degré d’implication dans la vie sociale.

Formation of linear plasmid multimers promoted by the phage lambda Red-system in lon mutants of Escherichia coli

We report here the formation of plasmid linear multimers promoted by the Red-system of phage lambda using a multicopy plasmid comprised of lambda red alpha and red beta genes, under the control of the lambda cI857 repressor. Our observations have revealed that the multimerization of plasmid DNA is dependent on the red beta and recA genes, suggesting a concerted role for these functions in the formation of plasmid multimers. The formation of multimers occurred in a recBCD+ sbcB+ xthA+ lon genetic background at a higher frequency than in the isogenic lon+ host cells. The multimers comprised tandem repeats of monomer plasmid DNA. Treatment of purified plasmid DNA with exonuclease III revealed the presence of free double-chain ends in the molecules. Determination of the size of multimeric DNA, by pulse field gel electrophoresis, revealed that the bulk of the DNA was in the range 50-240 kb, representing approximately 5-24 unit lengths of monomeric plasmid DNA. We provide a conceptual framework for Red-system-promoted formation and enhanced accumulation of plasmid linear multimers in lon mutants of E. coli.

Paleoenvironmental reconstruction of the coastal Monte Léon and Santa Cruz formations (Early Miocene) at Rincón del Buque, Southern Patagonia: A revisited locality

© 2015 Elsevier Ltd.Sedimentological, ichnological and paleontological analyses of the Early Miocene uppermost Monte León Formation and the lower part of the Santa Cruz Formation were carried out in Rincón del Buque (RDB), a fossiliferous locality north of Río Coyle in Santa Cruz Province, Patagonia, Argentina. This locality is of special importance because it contains the basal contact between the Monte Léon (MLF) and the Santa Cruz (SCF) formations and because it preserves a rich fossil assemblage of marine invertebrates and marine trace fossils, and terrestrial vertebrates and plants, which has not been extensively studied. A ~90m-thick section of the MLF and the SCF that crops out at RDB was selected for this study. Eleven facies associations (FA) are described, which are, from base to top: subtidal-intertidal deposits with Crassotrea orbignyi and bioturbation of the Skolithos-Cruziana ichnofacies (FA1); tidal creek deposits with terrestrial fossil mammals and Ophiomorpha isp. burrows (FA2); tidal flat deposits with Glossifungites ichnofacies (FA3); deposits of tidal channels (FA4) and tidal sand flats (FA5) both with and impoverish Skolithos ichnofacies associated; marsh deposits (FA6); tidal point bar deposits recording a depauperate mixture of both the Skolithos and Cruziana ichnofacies (FA7); fluvial channel deposits (FA8); fluvial point bar deposits (FA9); floodplain deposits (FA10); and pyroclastic and volcaniclastic deposits of the floodplain where terrestrial fossil mammal remains occur (FA11).The transition of the MLF-SCF at RDB reflects a changing depositional environment from the outer part of an estuary (FA1) through the central (FA2-6) to inner part of a tide-dominated estuary (FA7). Finally a fluvial system occurs with single channels of relatively low energy and low sinuosity enclosed by a broad, low-energy floodplain dominated by partially edaphized ash-fall, sheet-flood, and overbank deposits (FA8-11). Pyroclastic and volcaniclastic materials throughout the succession must have been deposited as ash-fall distal facies in a fluvial setting and also were carried by fluvial streams and redeposited in both estuarine and fluvial settings. These materials preserve most of the analyzed terrestrial fossil mammals that characterize the Santacrucian age of the RDB's succession. Episodic sedimentation under volcanic influence, high sedimentation rates and a relatively warm and seasonal climate are inferred for the MLF and SCF section.Lateral continuity of the marker horizons at RDB serve for correlation with other coastal localities such as the lower part of the coastal SCF south of Río Coyle (~17.6-17.4Ma) belonging to the Estancia La Costa Member of the SCF.

Biochemical and physiochemical characteristics of a pre-B cell stimulating factor produced by the plasmacytoma cell line LICR LON HMY2

We have characterized the pre-B cell colony stimulating activity (pre-B cell CSA) from LICR LON HMY2 conditioned medium (CM) by a variety of biochemical techniques. Pre-B cell CSA was found to be associated with a heat stable glycoprotein which has an isoelectric point of 8.3 and a mol. wt, as determined by polyacrylamide gel electrophoresis, of 28-32 kD. The relationship of this activity to previously described factors acting on cells of the B cell lineage is discussed.

Increased genome instability in Escherichia coli lon mutants: relation to emergence of multiple-antibiotic-resistant (Mar) mutants caused by insertion sequence elements and large tandem genomic amplifications

Thirteen spontaneous multiple-antibiotic-resistant (Mar) mutants of Escherichia coli AG100 were isolated on Luria-Bertani (LB) agar in the presence of tetracycline (4 microg/ml). The phenotype was linked to insertion sequence (IS) insertions in marR or acrR or unstable large tandem genomic amplifications which included acrAB and which were bordered by IS3 or IS5 sequences. Five different lon mutations, not related to the Mar phenotype, were also found in 12 of the 13 mutants. Under specific selective conditions, most drug-resistant mutants appearing late on the selective plates evolved from a subpopulation of AG100 with lon mutations. That the lon locus was involved in the evolution to low levels of multidrug resistance was supported by the following findings: (i) AG100 grown in LB broth had an important spontaneous subpopulation (about 3.7x10(-4)) of lon::IS186 mutants, (ii) new lon mutants appeared during the selection on antibiotic-containing agar plates, (iii) lon mutants could slowly grow in the presence of low amounts (about 2x MIC of the wild type) of chloramphenicol or tetracycline, and (iv) a lon mutation conferred a mutator phenotype which increased IS transposition and genome rearrangements. The association between lon mutations and mutations causing the Mar phenotype was dependent on the medium (LB versus MacConkey medium) and the antibiotic used for the selection. A previously reported unstable amplifiable high-level resistance observed after the prolonged growth of Mar mutants in a low concentration of tetracycline or chloramphenicol can be explained by genomic amplification.
