Mechanical Proprieties of Steel at High Temperatures
Ana-Diana Anca?,D. Gorbnescu
Bulletin of the Polytechnic Institute of Jassy, Constructions, Architechture Section , 2005,
Abstract: The experimental test results obtained in the study of steel mechanical proprieties variation in case of high temperatures (fire) are presented. The proprieties are referring to: Young’s modulus, E, the elastic limit, σe, and the characteristic diagram of the material (the rotation stress-strain). Theoretical laws that the model the steel behaviour at high temperature have been elaborated based on the most significant studies presented in the literature.
Theoretical Models in the Study of Temperature Effect on Steel Mechanical Properties
Ana-Diana Anca?,D. Gorbnescu
Bulletin of the Polytechnic Institute of Jassy, Constructions, Architechture Section , 2006,
Abstract: The governing laws adopted by two high qualified scientific organizations (D.T.U. and Eurocode) for the variation of steel mechanical properties at high temperatures are presented. There are no significant differences between them, but generally, the items advanced by Eurocode 3, part 1.2, are dopted in the most works that approach the thermical-mechanical analysis of steel structures.
Between the Barrio and the City: Pathways of Work among Scavenging Families  [PDF]
Débora Gorbán
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.24024
Abstract: In this article, I will reconstruct, through brief stories, some of the traits that characterize the way of life of families in the El Salvador neighborhood, in Buenos Aires, Argentina, go scavenging everyday in Buenos Aires city. These stories will not only tell us who they are and how they arrived at the El Salvador neighborhood, from where, and in what manner they began to salir con la carreta, but will also permit us to move closer to the day-to-day existence of these families in relationship to their life in the barrio and the activities they engage in, thereby giving us a fuller understanding of family dynamics. In the research that originated this paper, I followed an ethnographical perspective to study and analyze the way of life of those families living from the recyclable waste they recollect in Buenos Aires city.
El trabajo doméstico se sienta a la mesa: la comida en la configuración de las relaciones entre empleadores y empleadas en la ciudad de Buenos Aires
Débora Gorbán
Revista de Estudios Sociales , 2013,
Abstract: Domestic service comprises multiples dimensions that are related not only to the labour issues of women from popular sectors but also to the situation of social inequality that is at the root of this activity. The analysis that we propose in this text begins with the study of the construction of hierarchies and categorization that takes place in the context of interaction between employees and employers in the city of Buenos Aires. Specifically, this paper analyzes the place that food occupies in the context of the mentioned interactions, as an element through which social hierarchies are built. Our fieldwork was carried out in Buenos Aires, Argentina, between 2010 and 2011, following a qualitative approach.

Formas de organización y acción colectiva de desempleados y recicladores en el Conurbano Bonaerense
Cecilia Cross,Débora Gorbán
Revista Venezolana de Gerencia , 2004,
Abstract: El artículo centra la atención en las acciones colectivas que encuentran en la ausencia de trabajo asalariado su núcleo articulador, incluyendo la protesta, como expresión de poder que constituye un desafío y convoca a la solidaridad; la protesta es entendida como un momento de exposición directa, pública y disruptiva, de prácticas que la exceden. De allí la necesidad de dar cuenta de la interacción entre la realidad cotidiana y el momento crítico de la protesta, en tanto formas de sociabilidad que fortalecen la identidad, como motor y posibilidad de la acción colectiva. Metodológicamente el estudio recurre a entrevistas e historias de vida entre recicladores y trabajadores desempleados organizados, denominados piqueteros ; en la lectura de las entrevistas nos concentramos en el rastreo de aquellos aspectos y dimensiones de los relatos que ponen de relieve la crisis entre trabajo e identidad política, centrando el análisis, en aquello que los sujetos dicen en relación a la política y lo que ésta significa para ellos, tanto en función del pasado, como de cara al futuro.
AGONISTIC BEHAVIOR OF LABORATORY MICE
D. Cinghi??,D. St?nescu
Annals of West University of Timi?oara : Series of Biology , 2005,
Abstract: In this work we study agonistic behavior of laboratory white mice when they are kept in captivity. For all this experimental work we used direct observation of mice, in small lists, because we need a reduced space to emphasize characteristics of agonistic behavior. Relations between members of the same species that live in organized groups are based in most cases on hierarchical structure. Relations between leader and subservient, decided by fighting, involve a thorough observation between individuals. Each member of a group has its own place on the ierarchical scale depending on resultes of fhights – it can be leader or it can be subsurvient, depending on if it wines or looses the fight. Once hierarchical scale made, every animal will adjust its behavior. After analyzing the obtained data we have enough reasons to believe that after fights the winner, usually, is the massive mouse, but it is also very important the sexual ripeness, so the immature male will be beaten. The leader male had a big exploring area and it checks up all territory.The females can be more aggressive, its fights are more brutal, than male fights are, when they fight for supremacy, but in this case fights are not as frequent as in the case of males. Always the superior female, on hierarchical scale, shows males its own statute, so the strongest genes will be perpetuated.
A PRELIMINARY NOTE REGARDING SMALL MAMMAL FAUNA FROM THE WEST PLAINS OF ROMANIA
I. Duma,D. St?nescu
Annals of West University of Timi?oara : Series of Biology , 2003,
Abstract: This study reveals the results obtained from the researches made in the autumn and winter of 2003 and 2004 on small mammals fauna from the wetlands of Satchinez. The presentation is the first of this kind in the autochthon literature. The research was made within the “Life Natura“ project.
DATA ABOUT THE PRESENCE OF SYGNATHUS NIGROLINEATUS EICHWALD 1831 IN THE DANUBE RIVER
D. St?nescu,ROXANA OPRISANU
Annals of West University of Timi?oara : Series of Biology , 2004,
Abstract: In vorliegender Arbeit wird das Vorkommen der Seenadel (Syngnathus nigrolineatus Eichwald 1831) im ersten Abschnitt der Donau auf rum nischen Boden besprochen. Es erweist sich auf Grund meristischer Messungen und zugleich des genetischen Fingerabdrucks das zwischen den Küstenpopulationen des Schwarzen Meeres bei Agigea und derselben des künstlich endstandenen Ie elni a-Sees an der Donau ein wesentlicher Unterschied zu bemerken ist.
