Construir con madera  [cached]

Informes de la Construccion , 1998,
Abstract: The undoubtful advantages that construction with wood has as a counterpoint to the traditional ways used in dwelling-houses are briefly described in this article. Also it emphasizes the resistance of wood when facing fire and age, as compared to those structures made of steel, iron or concrete. Las indudables ventajas que aporta la construcción en madera como contrapunto a las formas tradicionales de concebir la vivienda en general, se describen - de manera somera- en este artículo. Se hace hincapié, asimismo, en la resistencia que presenta la madera en lo que respecta al paso del tiempo y frente al fuego, a diferencia de aquellas estructuras realizadas en acero, hierro u hormigón.

Abstract: in this article, i analyze a unique xix century work: manual de urbanidad y buenas maneras by manuel antonio carre?o, which consists of a collection of norms that modelled public and private life in caracas society within the sociopolitical context of a modernizing process during those times. in the first part, i analyze the manual as a type of discourse inserted and adjusted to xix century caracas society society. in the second part, i show the relationship between carre?o′s prescriptive norms and the basic ideas found in pragmatic theories. i take the concepts of positive and negative face and conversational maxims to reveal the structure of this sociopragmatic and ethnographic treatise of xix century venezuela.

Physics , 2000, DOI: 10.1103/PhysRevLett.84.4112
Abstract: We present neutron powder diffraction results which give unambiguous evidence for the formation of the recently identified new crystalline ice phase[Lobban et al.,Nature, 391, 268, (1998)], labeled ice XII, at completely different conditions. Ice XII is produced here by compressing hexagonal ice I_h at T = 77, 100, 140 and 160 K up to 1.8 GPa. It can be maintained at ambient pressure in the temperature range 1.5 < T < 135 K. High resolution diffraction is carried out at T = 1.5 K and ambient pressure on ice XII and accurate structural properties are obtained from Rietveld refinement. At T = 140 and 160 K additionally ice III/IX is formed. The increasing amount of ice III/IX with increasing temperature gives an upper limit of T ~ 150 K for the successful formation of ice XII with the presented procedure.

Abstract: Introduction. The study of the biological aspects of Anopheles spp., strengthens the entomological surveillance. Objective. To determine biological aspects and behavior of adult Anopheles mosquitoes in the urban area of Puerto Carre o municipality, Vichada, Colombia. Materials and methods. Wild anophelines were collected landing on humans both indoors and outdoors between 18:00h and 06:00h for 50 min/h during two consecutive nights/month for eight months in the urban area of Puerto Carre o. The biting rate activity, the natural infection by Plasmodium falciparum and P. vivax VK247 and VK210 using ELISA, and the annual entomological inoculation rate were determined for each species. The members of the Albitarsis complex were determined by amplificacion of the white gene by polymerase chain reaction. Results. In order of abundance the species found were An. darlingi (n=1,166), An. marajoara sensu stricto (n=152), An. braziliensis (n=59), An. albitarsis F (n=25), An. albitarsis sensu lato (n=16), An. argyritarsis (n=3) and An. oswaldoi sensu lato (n=2). An. darlingi showed two activity peaks between 21:00 to 22:00 and 05:00 to 06:00 hours outdoors and between 21:00 to 22:00 and 04:00 to 05:00 indoors. Natural infection of this species was found with P. vivax VK210 and its annual entomological inoculation rate was 2. Natural infection of An marajoara sensu stricto with P. falciparum was found, with an annual entomological inoculation rate of 5 and a peak biting activity between 18:00 to 19:00 hrs both indoors and outdoors. Conclusion. Transmission of malaria in the urban area of Puerto Carre o, Vichada, can occur by An. darlingi and An. marajoara s. s. Introducción. El estudio de los aspectos de la biología de los mosquitos Anopheles spp. fortalece la vigilancia entomológica. Objetivo. Determinar los aspectos de la biología y el comportamiento de las especies adultas del género Anopheles presentes en el área urbana de Puerto Carre o. Materiales y métodos. Se capturaron Anopheles spp. silvestres que se habían posado en personas, en el intradomicilio y peridomicilio de viviendas ubicadas en el área urbana del municipio de Puerto Carre o (Vichada), entre las 18:00 y las 06:00 horas, durante dos noches consecutivas por mes y durante ocho meses. Se determinó la actividad de picadura para cada especie, la infección natural por Plasmodium falciparum y P. vivax VK247 y VK210 mediante la técnica ELISA, y se determinó la tasa de inoculación entomológica. Los individuos pertenecientes al complejo Albitarsis se determinaron mediante amplificación en cadena de la polimer

Abstract: clara wieck, later schumann, germán, teresa carre?o, venezuelan, rosita renard, chilean, have all of them distinguished as some ofthe most outstandingpianists along a little more than a century, from befare the mid 19th century fo the mid 20th. there are parallelisms and contrasts in their uves and careers. rut their uves as well as their musical development were strongly affected by facts linked to their condition as women. we have tried to establish these parálisis, higlighting particularities and difficulties arisingfrom their condition of women.

Revista musical chilena , 2010,
Abstract: Clara Wieck, después Schumann, alemana, Teresa Carre o, venezolana, Rosita Renard, chilena, se distinguen como algunas de las más destacadas pianistas a lo largo de un poco más de una centuria, desde algo antes de mediados del siglo XIX a la mitad del XX. Hay paralelismos y también contrastes en sus vidas y sus carreras. Pero tanto el transcurrir de sus existencias como el del quehacer musical al que se dedicaron están marcados por hechos ligados a su condición de mujeres. Tratamos de hacer un paralelo entre sus vidas y entre el desarrollo de sus carreras destacando las particularidades y dificultades que en ambos planos les impuso la condición de mujeres. Clara Wieck, later Schumann, Germán, Teresa Carre o, Venezuelan, Rosita Renard, Chilean, have all of them distinguished as some ofthe most outstandingpianists along a little more than a century, from befare the mid 19th century fo the mid 20th. There are parallelisms and contrasts in their Uves and careers. Rut their Uves as well as their musical development were strongly affected by facts linked to their condition as women. We have tried to establish these parálisis, higlighting particularities and difficulties arisingfrom their condition of women.

Abstract: The author continues the development of the subject Modern Timber Formwork , by summing up the comparative examination —already carried out in Part III of this Study— of the different types of glued timber existing on the market. In addition, the loads and stresses allowable for coniferous timber and the proposal for establishing Regulations for the Timber Section of the Research and Experimental Forestry Institute of Spain are given. In part V of the author's Study, published in this article, the important subject of the glues used for joining timber, a truly vital point in order to obtain louvered timber beams which are simply glued together, is approached. El autor continúa el desarrollo del tema sobre Encofrados de madera modernos , resumiendo el estudio comparativo —ya hecho en la Parte III de este Estudio— de las diferentes vigas de madera encolada existentes en el mercado dando, además, las cargas y tensiones admisibles para maderas coníferas y la propuesta de Reglamentación de la Sección de Maderas del Instituto Forestal de Investigaciones y Experiencias de Espa a. En la parte V del Estudio del autor, publicada en este articulo, se aborda el importante tema de las colas empleadas para las uniones de madera, algo realmente vital para la obtención de vigas de madera en celosía simplemente encoladas.
