Utopía social y utopía tecnológica en el pensamiento de las izquierdas argentinas para la transformación del capitalismo agrario, 1890-1945
Graciano,Osvaldo;
Mundo agrario , 2010,
Abstract: the objectives of this work are to rebuild the communist and socialist thinking and the political proposals used, between 1890 and 1945, to set a new model of economics and society within the agrarian sector in the pampas region, and which, on its basis, include elements of social and technological utopias. along the first half of the twentieth century, the left wings developed several projects aimed to transform the agrarian economics and society in argentina and thus, tried to influence the modifications of social and economics rural relations dominant in the country, and in particular in the pampas region. those proposals started to throw the imaginary of a rural world different to the current upon the speech and the political thinking of the left wings. in many of them shaped as a social utopia and in others shaped as a technological utopia, for its realization.
Nitrato lixiviado de columnas de suelo sin disturbar, pertenecientes a dos suelos de la Cuenca del Lago de Valencia
Marcano,Lily; Elizalde,Graciano;
Revista de la Facultad de Ingeniería Universidad Central de Venezuela , 2010,
Abstract: nitrate leaching was assessed in undisturbed soil columns in two agricultural soils. initially, nitrate content at different horizons was much higher in lacustrine soil than in the alluvial soil. in lacustrine soil, nitrate leaching gradually increased, reaching the highest peak at day 72, when it started to decrease, while the alluvial remained virtually constant throughout the experiment. nitrate leaching concentration in lacustrine soil (50.48 mg l-1) is 5 times higher than the maximum tolerable limit for environmental standards. in alluvial soil it was lower (20.78 mg l-1), but it is still twice the maximum acceptable concentration. therefore, it is considered that irrigation acts as a promoter of the processes of nitrification produced by microorganisms in the soil at the expense of organic matter, which leads to loss of no3- through lixiviation. because of the higher content of organic matter, high permeability and higher requirements of irrigation water, the absolute amounts of nitrate leaching in lacustrine soil were much higher (436 mg) than that of alluvial soil (30 mg) after 4 months

Along the first half of the twentieth century, the left wings developed several projects aimed to transform the agrarian economics and society in Argentina and thus, tried to influence the modifications of social and economics rural relations dominant in the country, and in particular in the Pampas Region. Those proposals started to throw the imaginary of a rural world different to the current upon the speech and the political thinking of the left wings. In many of them shaped as a social utopia and in others shaped as a technological utopia, for its realization. Este trabajo tiene como objetivos reconstruir el pensamiento socialista y comunista y las propuestas políticas con las que buscaron entre 1890 y 1945, concretar un nuevo modelo de sociedad y economía en el agro pampeano y que en sus fundamentos inscribían elementos de las utopías sociales y las tecnológicas. A lo largo de la primera mitad del siglo XX las izquierdas formularon diversos proyectos para la transformación de la economía y la sociedad agrarias argentina, intentando con ellos incidir en la modificación de las relaciones económicas y sociales rurales dominantes en el país y en particular en su región pampeana. Esas propuestas fueron proyectando en el discurso y en el pensamiento político de izquierdas el imaginario de un mundo rural alternativo al vigente, tomando en muchas de ellas la forma de la utopía social y en otras la de la utopía de tipo tecnológico para su realización.
Estado, Universidad y economía agroexportadora en Argentina: el desarrollo de las facultades de Agronomía y Veterinaria de Buenos Aires y La Plata, 1904-1930
Osvaldo Fabián Graciano
Revista Theomai , 2003,
Abstract: This paper has the main purpose of reconstructing the historical development of the first Agronomy and Veterinary department of the country, in the national universities of Buenos Aires and La Plata. The creation of these institutes of agrarian teaching in the first years of the XX century, was impelled by the national State with the objectives of organise a scientific complex of research and agricultural experimentation and to form the professional resources that could manage, within the state bureaucratic apparatus, the productive development of the agricultural economy of the Pampas. The development of the above mentioned departments was also the answer from the State to the demands of the cattle sectors of the Pampas that had promoted the agronomic and veterinary teaching in the country as from the end of the XIX century.
Statistical Mechanics of Two-player Iterated Games
Rui Dilao,Joao Graciano
Quantitative Biology , 2005,
Abstract: We construct a statistical ensemble of games, where in each independent subensemble we have two players playing the same game. We derive the mean payoffs per move of the representative players of the game, and we evaluate all the deterministic policies with finite memory. In particular, we show that if one of the players has a generalized tit-for-tat policy, the mean payoff per move of both players is the same, forcing the equalization of the mean payoffs per move of both players. In the case of symmetric, non-cooperative and dilemmatic games, we show that generalized tit-for-tat policies together with the condition of not being the first to defect, leads to the highest mean payoffs per move for the players.
Comparisons of the Properties of Whitemouth Croaker (Micropogonias furnieri) Surimi and Mechanically Deboned Chicken Meat Surimi-Like Material  [PDF]

Abstract:

The aim of this work was to evaluate and compare the color, texture and sensory characteristics of whitemouth croaker (Micropogonias furnieri) surimi and mechanically separated chicken meat (MDCM) surimi-like material (SLM). The whiteness of the MDCM-SLM was higher (P > 0.05) than that from the surimi. Higher breaking force (P < 0.05) and gel strength (P < 0.05) were also observed for the MDCM-SLM when compared to the surimi. The deformation did not vary significantly for these two products (P > 0.05). The MDCM-SLM was more accepted by the panelists (P < 0.05). The mean scores of overall desirability for MDCM-SLM was similar to that observed for walleye Pollack surimi that is the parameter of quality. The differences in the acceptability of poultry and fish food products are probably due to peoples’ eating habits.
