Cartelization process in institutionalized environments: legitimation and political communication
2017
International audience; The main objective of this paper is to analyze cartel party tendencies toward professionalization of communicative institutional processes (Mair, 015).The main role of the media in a audience democracy is indisputable (Manin, 1998). So the media politics are one of the main features of public space. In this way, Political parties have become platforms of placement of their leaders to occupy the largest number of institutional positions. Consequently, this phenomenon has spread as a common practice of our political system. The emergence of partisan elite, which has professionalized itself in high political-institutional positions, has colonized the leadership of publi…
Spermatocytes of the caddisfly Potamophylax rotundipennis (Trichoptera, Insecta): a fine structure study with emphasis on synaptonemal complex plates…
1996
Abstract Electron microscopy of ultrathin sections was used to study the restructuring of primary spermatocytes in a caddisfly, Potamophylax rotundipennis (Limnephilidae). Spindle structure was also examined using light microscopy of dividing spermatocytes lysed in a microtubule-stabilizing buffer. The bulk of pachytene spermatocytes was usual in that the nuclei contained tripartite synaptonemal complexes (SCs). The SCs were attached end-on to the inner face of the nuclear envelope and loosely surrounded by electron-dense chromatin. Cells of this type gave rise to late prophase I spermatocytes, where SCs were missing and chromatin condensation was advanced. By metaphase I, a conventional bi…
Effects of temperature, pH and sugar concentration on the growth parameters of Saccharomyces cerevisiae, S. kudriavzevii and their interspecific hybr…
2008
The effects of temperature, pH and sugar concentration (50% glucose + 50% fructose) on the growth parameters of Saccharomyces cerevisiae T73, S. kudriavzevii IFO 1802T and the hybrid strain S. cerevisiae × S. kudriavzevii W27 were studied by means of response surface methodology based in a central composite circumscribed design. Lag phase could not be properly modelled in the wine model system, where yeasts started the fermentation in few hours after inoculation. In the case of the maximum specific growth rate (μ max), the temperature was the most important variable for three yeasts, although the effects of sugar concentration (in T73 and W27) and pH (W27 and 1802) were also significan…
Effect of the natural winemaking process applied at industrial level on the microbiological and chemical characteristics of wine.
2013
The composition of yeast and lactic acid bacteria (LAB) communities and the chemical evolution of the large-scale commercial vinification of Catarratto IGT Sicilia, carried out under the biological regime, was followed from grape harvest until bottling. Simultaneously to the maximum growth of yeasts, LAB counts reached high level of concentration (6-7 log CFU mL(-1)) during the first steps of the alcoholic fermentation. Yeast identification was determined applying different molecular methods. The highest species biodiversity was observed on grape and must samples taken soon after pressing. Saccharomyces cerevisiae was detected at dominant concentrations during the entire winemaking process.…
Biochemical aspects of stuck and sluggish fermentation in grape must
1998
Recently a number of studies have focused on the factors responsible for the occurrence of stuck and sluggish fermentations. Results from these studies indicate that together with nutritional deficiencies and inhibitory substances, technological practices could lead to such situations. This review explains, from a biochemical point of view, the influence of nutritional deficiencies, inhibitory substances and technological practices on yeast cell development and physiology and the fermentation process.
NEMATODE COLONIZATION OF PYRITE CINDER-POLLUTED SOIL
2020
The nematofauna was studied in the early stages of a remediation trial at an industrial site where pyrite cinders had accumulated for 40 years in a large area and were then covered with mineral soil. The cinders were contaminated with several metals and metalloids. The soil of the experimental plots was derived from the mixture of cinders with the covering soil in a 1:1 ratio. Plots were amended with manure and sown with 3 metal resistant plants: Sorghum bicolor L., Helianthus annuus L., and Arundo donax L. Samples were taken : a) at the beginning of the trial on the pyrite cinders and covering soil, separately; b) from the mixture before the application of manure; c) from cultivated plots.…
Crisis y renovación en el cine de animación argentino. el caso de el empleo
2016
Los procesos de crisis modifican el imaginario social e influyen en la creación artística y en los productos culturales. El objetivo de este trabajo es averiguar la incidencia de la crisis Argentina de 2001 en el cine de animación. A partir del análisis audiovisual de la película El empleo (Santiago Grasso, 2008), buscamos qué elementos se problematizan y qué tipo de discurso plantea. Las conclusiones del trabajo pretenden ampliar la cobertura de los estudios académicos centrados en el impacto de la crisis sobre los productos culturales también al ámbito del cine de animación contemporáneo.
Bram Stoker's Dracula y el prerrafaelismo
1995
La mayoría de versiones cinematográficas basadas en la novela Dracula de Bram Stoker se encuadran en el estilo inaugurado por la llamada "novela gótica" iniciada en el siglo XVIII y culminada en el romanticismo decimonónico. Sin embargo, la película Bram Stoker's Dracula, realizada por F. F. Coppola y su equipo, se ha inspirado en otras fuentes estéticas: el simbolismo y el prerrafaelismo del siglo XIX. El espíritu prerrafaelista es recreado en el ambiente del film y en el uso de diseños basados en los de William Morris para decorar parte del mobiliario y del vestuario, asi como por el aspecto físico de los tres vampiros femeninos basados en la tipología femenina de pinturas de Dante Gabrie…
Las dos Valencias cinematográficas del 36
2008
La revisión somera de las imágenes cinematográficas que tratan de Valencia y su región por los dos bandos revela la heterogeneidad de la propaganda de ambos y de algunos de los credos que habitaron entre los muros de la República. Sin embargo, la pregunta clave que el historiador precisa hacerse es: ¿qué documenta el cine cuando muchas de estas cosas ya las conocemos por otros medios? La ambigüedad se impone en este punto, puesto que habitualmente el cine todavía no ha ascendido a la condición de documento único y se mantiene, por el contrario, en el estatuto secundario de ilustración, como ya denunció Peter Burke (2005) para la imagen pictórica tiempo atrás. Por una parte, el cine fue un i…
Shooting in the ghetto: On the migration of film footage
2013
En 2010, un documental germano-israelí –A Film Unfinished– recuperaba enigmáticos planos rodados por un equipo de cineastas alemanes (Propaganda Kompanien) en el ghetto de Varsovia durante la primavera de 1942. Una porción considerable de estos planos que el Ministerio de Propaganda de Goebbels decidió no utilizar por confusas razones ya había circulado profusamente en films anteriores, desde los años 50. Depositados en los archivos de la DEFA, habían sido utilizados a contrario en primer lugar por cineastas de la RDA y de la DDR: tratando de denunciar a sus autores. Dicho de otro modo, las imágenes llamadas a denigrar a los judíos servían para denunciar a sus autores, convirtiéndose en efi…
