Lightweight SFRC benefitting from a pre-soaking and internal curing process

The presented research program is focused on the design of a structural lightweight fiber-reinforced concrete harnessing an internal curing process. Pre-soaked waste red ceramic fine aggregate and pre-soaked artificial clay expanded coarse aggregate were utilized for the creation of the mix. Copper-coated steel fiber was added to the mix by volume in amounts of 0.0%, 0.5%, 1.0%, and 1.5%. Test specimens in forms of cubes, cylinders, and beams were tested to specify the concrete characteristics. Such properties as consistency, compressive strength, splitting tensile strength, static and dynamic modulus of elasticity, flexural characteristics, and shear strength were of special interest. The achieved concrete can be classified as LC12/13. A strength class, according to fib Model Code, was also assigned to the concretes in question. The proposed method of preparation of concrete mix using only pre-soaked aggregate (with no extra water) proved to be feasible.Web of Science1224art. no. 415

Reconfiguraciones organizacionales, procesos políticos y territorialización : los Huarpes como "comunidades indígenas"

En los años 1998 y 1999, un conjunto de familias reconocidas como Huarpes, residentes en el departamento de Lavalle, han sido inscriptas como "comunidades indígenas" en el Instituto Nacional de Asuntos Indígenas. Dichas familias vienen protagonizando un momento de reorganización social vinculado fundamentalmente a una constante lucha en defensa de su territorio. Conceptualizando el nucleamiento jurídico de los Huarpes en "comunidades indígenas" como situación histórica y la reestructuración social endógena resultante como proceso de territorialización, el objetivo central de este artículo es analizar los procesos administrativos y jurídicos a través de los cuales el Estado reconoce los derechos indígenas sobre la tierra y las implicancias que tienen en las formas organizacionales indígenas, respecto a sus valoraciones, demandas y estrategias de acción.In 1998 and 1999, a set of families recognized as Huarpes, residents in the department of Lavalle, has been inscribed as "indigenous communities" in the National Institute of Indigenous Subjects. These families come fundamentally developing a social reorganization to a constant fight in defense of their ten -itory. Thinking the legal organization of the Huarpes in "indigenous communities" like historical situation and the social reconstruction endogenous resultant like territorialization process, the central objective of this article is to analyze the administrative and legal processes through which the State recognizes the indigenous right on the territory and the implication that they have in the indigenous organization forms, with respect to its valuations, demands and strategies of action.Fil: Katzer, Leticia .

Virtual Construction for our industry – an advantage now, a necessity soon

Some key facts about the economic environment of construction industry are explained. It is shown that construction industry is very heterogeneous and has changed drastically during the recent years due to a rapidly moving commercial environment. Two examples of todays’s use of virtual construction tools in construction projects are presented. The first example is the document control for a large international project. The second is the application of 4D modelling in the preconstruction phase of a dam project. It is shown that virtual construction, is a major international trend that currently takes up speed. Some generic industry needs for Research and Development which aims at short and medium term results are presented

Razón gubernamental, biopolítica y mecanismos de capitalización de la praxis indígena en Mendoza

En un mundo en constante transformación, los dispositivos pedagógicos también se modifican. La escuela produce nuevas formas de regular las conductas, distintas a las que conocimos en las sociedades disciplinarias. Para dar cuenta de esos cambios, focalizaremos la atención en algunas situaciones discursivas de los docentes, padres y estudiantes en la escuela, que nos permiten aproximarnos a las prácticas de regulación cotidianas y también a las formas de oposición, de contraconductas o conductas en la escuela del siglo XXI.In a constantly changing world, educational devices also change. The school produces new forms of behavior regulation, different from those we met in disciplinary societies. To give an account of these changes we will focus on certain school situations through discursive practices of teachers, parents and students, which will allow us to approach day-to-day regulatory practices and also the forms of opposition, counter-conducts or conducts that in its generality cannot take place in the XXIth century school.Fil: Katzer Molina, Maria Leticia.

Colonialidad/modernidad como matriz de subjetivación étnica: lecturas desde la crítica biopolítica, el pensamiento de la comunidad y la deconstrucción

El propósito del artículo es explorar las formas teóricas y jurídicas coloniales/modernas de estructuración de la vida-en-común en el campo de la etnicidad, analizándolas como un entramado que articula la matriz biopolítica y de la gubernamentalidad con el dispositivo de la persona y el paradigma inmunitario. Para nuestro análisis articulamos centralmente tres corpus teóricos: el foucaultiano, en su propuesta epistemológica y metodológica como su crítica biopolítica y analítica de la subjetividad moderna; el derridiano, en su propuesta de pensamiento sobre lo político; y el de la crítica epistemológica del colonialismo. Tomamos centralmente dos tesis desde cierta distancia crítica: a) la colonialidad constituye una expresión de la modernidad y b) lo que conecta la biopolítica con la modernidad es el paradigma inmunitario.The purpose of this article is to explore the colonial / modern theoretical and juridical forms of life-in-common structuring in the field of ethnicity, analyzing them as a network that articulates the biopolitical and the governmentality matrices with the dispositif (apparatus) of the person and the immune paradigm. For our analysis, we articulate three theoretical corpuses: the Foucauldian, in its epistemological and methodological proposal as its biopolitical and analytical critique of modern subjectivity; the Derridean, in its proposal of thought on political issues; and that of the epistemological critique of colonialism. We centrally take two theses from a certain critical distance: a) coloniality is an expression of modernity and b) what connects biopolitics with modernity is the immune paradigm.Fil: Katzer Molina, Maria Leticia.

Desert ethnographies : reflections from an anthropology of nomadism

l presente artículo contiene una serie de reflexiones, elaboradas sobre la base de nuestra propia investigación etnográfica, que intentan contribuir a desnaturalizar y visibilizar la complejidad de los contextos de interacción, considerando que abarcan distintas dimensiones y aspectos –tales como posición de los interlocutores en la estructura social, expectativas individuales, experiencias y relaciones previas de los sujetos, y recursos materiales y simbólicos en intermediación–, enfatizando así el carácter situacional y dinámico de esas relaciones de interlocución. A la luz de los actuales debates de la crítica cultural, el pensamiento nómade y la crítica espectrológica derridiana, y en un intento por contribuir a los estudios de la Etnografía Colaborativa, el objetivo de este artículo es exponer lo que entendemos como performances de campo, situando como objeto de análisis la experiencia etnográfica en sí misma.This paper contains a series of reflections developed on the basis of the author’s own ethnographic research, carried out since 2004 with indigenous Huarpe people in the province of Mendoza, Argentina. These reflections try to contribute to denature the complexity of interaction contexts and make them visible, considering that such contexts embrace different dimensions and aspects –such as the speakers’ position in the social structure, individual expectations,experiences and previous relationships of subjects, as well as material and symbolic intermediation resources. Emphasis is therefore placed on the situational and dynamic character of those interlocution relationships. In the light of current debates from cultural review, the nomad thinking and the Derridean spectrological critics, and in an effort to contribute to the Collaborative Ethnography studies, this paper is aimed at showing what we understand as field performances, considering the ethnographic experience itself as the object of analysis.Fil: Katzer Molina, Maria Leticia.

Léxicos políticos en tensión: Movilización étnica indígena e impolítica en Argentina

El siguiente artículo reúne reflexiones y perspectivas analíticas resultantes de mi investigación doctoral, la cual indaga sobre las articulaciones entre identidad, economía y política. A partir de un estudio de caso etnográfico los Huarpes- y de la selección de un contexto regional específico- la provincia de Mendoza- este trabajo constituye un esfuerzo por indagar y analizar las formulaciones políticas inherentes al actual régimen gubernamental, revisando críticamente sus supuestos y analizando sus efectos sobre las formas de organización indígena. En el léxico de gobierno contemporáneo, la vida indígena- definida como "vida pura" -entra en el mundo de lo humano sólo cuando se la inscribe en un orden normativo en este caso, el "sistema de comunidades indígenas"-, el cual busca brindarle una forma ordenada, uniforme y estable desde una racionalidad económica.The following article collects reflections and analytical perspectives that result of my doctoral research that explore about relationships between identity, economy and politics. By means of an ethnographic case study – the Huarpes- and the choice of a specific region– the province of Mendoza- this work is the result of an effort to enquire and to analyze the political formulations inherent to the present configuration of the government regime, critically reviewing their budgets and analizing their effects on indigenous organizational ways. In the lexicon of contemporary government, the indigenous life – defined it as “pure life”- enters of the human world, only when she is registered in a normative order - in this case, the " system of indigenous communities "-, which, it searchs give him a tidy, uniform and stable form, from economic rationality.Fil: Katzer Molina, Maria Leticia.

Human Papillomavirus Vaccine Frequency for University of Kansas Medical Center Pediatric Patients

Background. Human papillomavirus (HPV) vaccination is recommendedfor all adolescents aged 11 to 12 years, but coveragein Kansas is exceptionally poor. To understand local coverage, receiptof the 3-dose HPV vaccine series among pediatric patients atthe University of Kansas Medical Center (KUMC) was evaluated. Methods. All patients aged 11 to 12 years who were seen by aKUMC primary care provider (family medicine and pediatrics)in 2013 were included in the retrospective chart review. Recordswere reviewed through December 31, 2014 to capture the numberof HPV doses received, and receipt of other recommendedvaccines (tetanus-diphtheria-pertussis and meningococcal conjugate).Pearson’s chi-squared tests were used to evaluate relationshipsbetween HPV vaccination and patient characteristics. Results. Of the 261 eligible females and 243 eligible males, 71.2%received ≥ 1 HPV vaccine dose, 55.2% received ≥ 2 doses, and39.3% completed the HPV vaccine series (3 doses). Although vaccineinitiation was slightly lower in males compared to females(67.1% vs. 75.1%, p = 0.047), no difference in vaccine completionwas seen between males and females (37.0% vs. 41.7%, p = 0.319).Over 80% of patients received other concurrently recommendedvaccines (Tdap: 81.7%, meningococcal: 81.3%). HPV series completionoccurred more often among Spanish-speaking femalescompared to English-speaking females (59.5% vs 37.7%; p < 0.01).Conclusions. The proportion of adolescents who received theHPV vaccination at KUMC is substantially higher than nationaland state estimates, but there is room for improvement forboth initiation and series completion.
