For the detection of Enterovirus, we devised a direct economical method of polymerase chain reaction which does not require a previous extraction of ribonucleic acid and uses infected cell culture supernatants. The system was developed on the basis of universal primers of Enterovirus and specific primers of vaccinal strain Sabin 1. The achieved results proved that the non-existence of methods of R
Tyckare och experter förfäras över det hemska nätet och de ohyfsade ungdomarna. Men det kommer någonstans ifrån. Barn gör inte som vuxna säger, de gör som vuxna gör. Det skriver Marcin de Kaminski, nätforskare och doktorand i rättssociologi, och Katia Wagner, frilansjournalist och föreläsare kring ungas vardag på internet.
Abstract in French La thèse est une édition partielle d'une version particulière de l'histoire en prose de Tristan et Yseut. Le ms. fr. 103 diffère en effet de la version "vulgate" de l'histoire en plusieurs points et ne présente pas les longueurs que nous pouvons reconnaître dans la version maintenant éditée dans son intégralité. Le remanieur de l'histoire des deux amants légendaires a en effet é
Abstract in Spanish:Las redes de transporte urbano constituyen un espacio social en el que los agentes se relacionan con múltiples artefactos –señales, reductores de velocidad, puentes, otros vehículos, etc.– Como lo advierte Latour, el estudio de dicho entorno social necesita ser “materializado”, en este caso, considerando la infraestructura, que permite –o no– el uso fluido del sistema, como parUrban transport network is a social space in which agents interact with multiple artifacts –signs, speed bumps, bridges, other vehicles, etc.– As Latour states, the study of social spaces needs to be “materialized”, in this case, considering the material infrastructure that allows –or not– the fluid use of the system, as a fundamental part of the analysis of the transport phenomenon. From an agent
Extrusion is used to produce crunchy expanded foods, such as snacks. The nutritional impact of this process has not been studied sufficiently. In this study, in vitro and in vivo protein and starch bioavailability was evaluated in both raw and extruded corn (Zea mays)(C) and lima bean (Phaseolus lunatus)(B) flour blends, prepared in 75C/25B and 50C/50B (p/p) proportions. These were processed with
The article examines the contributions of Arthur W. Galston (1920–2008) and Polly Higgins (1968–2019) to the concept of ecocide, from its origins in the Vietnam War to its revival in the twenty-first century. Biologist Arthur W. Galston, whose doctoral research was used to investigate defoliating agents, led a scientific campaign in the late 1960s against the massive use of herbicides by the Unite
Objective: To determine the circulation of poliovirus in three municipalities considered as transitory points for migrants in Colombia. Material and Method: Wastewater samples (n = 36) were collected from border municipalities, selected for greater transit of regular and irregular migrants, in the period between 2017-2019. The samples were concentrated and cultured following the World Health Organ
Abstract in frenchAvec la Vie de Saint Louis, datée de 1309, Jean de Joinville a légué à la postérité un texte hybride qui n’accepte aucune classification définitive. Son « je » est le tout premier de la littérature française, et pour les historiens, l’intérêt de son récit, réside en la description de la Septième croisade. L’objectif de ce mémoire est de considérer, sous l’angle de l’écriture de l
This thesis contains two studies focusing on motivation in learning and teaching French as a foreign language in Sweden. In the first study, the effect of three specifically designed pedagogical activities on learners’ Ideal French Self (IFrS) and Intended Effort (IE) was examined in a group of 15-year-old Swedish pupils. No significant difference could be found between the two intervention classe
The substrate preparation for CVD diamond growth is of basic importance due to several reasons. A new molybdenum substrate preparation method, the aluminum oxide abrasion jetting, is introduced and compared with the traditional ones. Raman Scattering Spectroscopy (RSS) and Scanning Electron Microscopy (SEM) characterize CVD diamond films. CVD diamond films of good quality and uniformity were obtai
This work was performed to quantify the performance of extracts and saponins in residues generated by exporters of quinoa in the departments of La Paz, Oruro and Potosi, determining that the extraction yields range from 36.0 % to 39.4 % w/w, while the percentage of saponins in the extract ranged from 47.3 % to 56.2 % and saponins in the residues from 17.3 % to 22.1 %. Additionally, a method was op
Det individuella och det kollektiva är två begrepp som ständigt utforskas i den spanska författarinnan Belén Gopeguis verk. Den här uppsatsen utgår från observationen att relationen mellan de två behandlas som en sammanflätning. Dess roll i Gopeguis politiskt-litterära projekt undersöks, där det kollektiva presenteras som en förutsättning för de förändringar som projektet eftersträvar. Verket i al
