Las herramientas que construyeron el árbol de la vida
María Susana Rossi
Química Viva , 2005,
Abstract: Una de las características que nos distinguen del resto de los seres vivos es el lenguaje. Como parte de su mecanismo, necesitamos describir aquello que nos rodea, lo que implica asignar nombres que permitan identificar a los objetos animados e inanimados. Como consecuencia de la gran cantidad de elementos descriptos, y frente a la necesidad de entender a qué nos referimos, surgen las diferentes maneras de clasificarlas. Este artículo repasa la historia de la clasificación de los seres vivos, desde las primeros intentos de ordenar los organismos utilizando un lenguaje común basado en sus propiedades, los nombres de especies latinizados binomiales propuestas por Carl von Linné (conocido como Linneo) que aún hoy se utilizan, hasta la nueva filogenia, derivada de las técnicas de biología molecular que surgieron a fines de la década del 70, que incluye a especies nunca vistas por el hombre, conocidas sólo a través de su secuencia de RNA ribosomal; su firma molecular

Abstract: abstract tuberculosis constitutes a worldwide major health problem and concerted effort to obtain an opportune diagnosis is needed. the infections caused by non-tuberculous mycobacteria (ntm) add to the diagnosis challenge. in this work we isolated and identified mycobacteria, using bacteriological and molecular methods, from 256 clinical samples obtained of 188 patients with diagnostic impression of tuberculosis. from forty one samples with isolation (16%), 24 were baciloscopy positive (bk+), 58,5% and 17 were bk- (41,5%). m. tuberculosis represented 58.14% of all isolated mycobacteria and ntm were present in 37,2%: 6 m. chelonae, 4 m. marinum, 3 m. fortuitum, 3 no identified. the correlation between the bacteriological and molecular identification methods was 93%. the presence of a high percentage of ntm obtained from clinically ill patients indicates the importance to include them in the differential clinical diagnosis and implementation the culture as obligate bacteriological diagnostic tool

Abstract: we inscribe this article in the new studies of land and procure to solve some questions related to the occupation of the ground beyond the bonaerense′s campaign; we will try to make a rapprochement to the big processes of appropriation and transfer of land in the north salado border, in the matará district, made by the local socio-political elite. we will analyze the mechanisms used to legally access the property of land and the business between the state and the individuals which were born with the new territories at disposal and considered "public land".

Abstract: this article pretends to analyze the different ways through which the liberal santiaguenian elite planned the capitalist implantation from the second part of the xix century and the different projects of modernization in the economical area of a territory characterized by historical marginality, unequal and extreme ecological areas, and scanty economical sources to go ahead. ascribing to the philosophy of progress, following the alberdian ideas and ready to insert the santiaguenian productions in the economical circumference of the capitalist system, this elites -as far as they were also the state- developed some practices whose first objective was the study of the economical areas where the livestock productions demanded by the european market could take place. the conjunction of the local interests with the european needs will lead to the study of the salado norte river valley, the dulce river valley and the place known as mesón de fierro (iron table). this three areas will be connected between themselves and with the paraná river ports by the railway.

Inscribiendo al artículo en los nuevos estudios de tierras y procurando resolver algunos interrogantes en relación a la ocupación del suelo más allá de la campana bonaerense, nos aproximaremos a los grandes procesos de apropiación y traspaso de los territorios de la frontera del Salado del Norte, en el Departamento Matará, llevados adelante por la elite socio-política local. Analizaremos los mecanismos utilizados para acceder legalmente a la propiedad de la tierra y los negocios entre el estado y los particulares generados con los nuevos territorios en disponibilidad considerados "tierra pública".

Ascribing to the philosophy of progress, following the alberdian ideas and ready to insert the santiaguenian productions in the economical circumference of the capitalist system, this elites -as far as they were also the State- developed some practices whose first objective was the study of the economical areas where the livestock productions demanded by the European market could take place. The conjunction of the local interests with the European needs will lead to the study of the Salado Norte River valley, the Dulce River valley and the place known as Mesón de Fierro (Iron Table). This three areas will be connected between themselves and with the Paraná River ports by the railway. El objeto de la presente comunicación es analizar los modos en que, desde mediados del siglo XIX, la elite liberal santiagueňa, planteó la implantación capitalista y los diversos proyectos modernizadores en el área económica, en un territorio signado por la marginalidad histórica, espacios ecológicos dispares y extremos y escasos recursos económicos para concretar acciones estratégicas de magnitud. Enrolada en la filosofía del progreso, seguidora de los postulados alberdianos y dispuesta a incorporar a las producciones santiagueňas en los circuitos económicos del sistema capitalista, en tanto Estado, llevaron adelante unas prácticas que tuvieron como primer gran objetivo, estudiar los espacios económicos potencialmente aptos para desarrollar las producciones pecuarias que el mercado europeo demandaba. De modo que una conjunción de intereses entre aspiraciones locales y demandas europeas, dará como resultado la evaluación de las potencialidades de tres espacios: la cuenca del río Salado del Norte, la cuenca del río Dulce y el espacio del "mesón de fierro". Enlazando las tres áreas, los proyectos ferroviarios con trazados que las relacionaban entre sí y con los puertos sobre el Paraná.

Abstract: the objective of this work is to show both experiences of multidisciplinary activities and the way to an interdisciplinary vision of the development of scientific ? technological investigations carried out at engineering faculty of the universidad nacional del centro de la provincia de buenos aires, under the investigation program "seed technology (tecse)". interdisciplinary teamwork is an inevitable quality in the xxi century scientist or professional. therefore a qualitative characteristic is imposed from a multidisciplinary work stage towards an interdisciplinary teamwork activity, turning a narrow vision of problems from a particular profession or science into an articulation of knowledge and interests to obtain an integral solution.
