Nú?ez Rangel, V;Fernández Culma, M;Rey-Suárez, P;Perea?ez, JA;
Journal of Venomous Animals and Toxins including Tropical Diseases , 2012, DOI: 10.1590/S1678-91992012000200007
Abstract: the snake genus lachesis provokes 2 to 3% of snakebites in colombia every year. two lachesis species, l. acrochorda and l. muta, share habitats with snakes from another genus, namely bothrops asper and b. atrox. lachesis venom causes systemic and local effects such as swelling, hemorrhaging, myonecrosis, hemostatic disorders and nephrotoxic symptoms similar to those induced by bothrops, portidium and bothriechis bites. bothrops antivenoms neutralize a variety of lachesis venom toxins. however, these products are unable to avoid coagulation problems provoked by lachesis snakebites. thus, it is important to ascertain whether the envenomation was caused by a bothrops or lachesis snake. the present study found enzyme linked immunosorbent assay (elisa) efficient for detecting lachesis acrochorda venom in a concentration range of 3.9 to 1000 ng/ml, which did not show a cross-reaction with bothrops, portidium, botriechis and crotalus venoms. furthermore, one fraction of l. acrochorda venom that did not show crossreactivity with b. asper venom was isolated using the same elisa antibodies; some of its proteins were identified including one gal-specific lectin and one metalloproteinase. this test may be useful to physicians, since it could be applicable for tracking the kinetic distribution of antigens in patients or experimentally envenomed animals.

Rect@ , 1998,
Abstract: En este trabajo presentamos dos conceptos relacionados con la solución de sistemas de ecuaciones no lineales y con desigualdades. El primer concepto es el de una función normal merit, que resume las propiedades básicas que tienen distintas funciones merit conocidas. El segundo concepto es el de un operador Newtoniano, cuyos valores generalizan el concepto de Hessiana para la función normal merit. Combinando el resultado del método generalizado de Newton con ciertos métodos de primer orden, obtenemos un algoritmo de convergencia global para minimizar funciones normales merit.

Abstract: A review of some relevant papers about the cutting of ornamental stones with diamond tools is presented here with the aim of being useful to the Natural Stone industries. Due to the length of this paper, it has been divided in two parts: in the first one, the influence of the factors of the cutting equipments (machinery, disks, cutting characteristics, etc) is reviewed, and in the second one, in the next number of this journal, attention will be paid to the intrinsic rock characteristics that influences its cuttability and, thus, the efficiency of the diamond tools. En este trabajo se hace una revisión de algunas publicaciones relevantes relacionadas con el corte de rocas ornamentales con discos diamantados, con el propósito de que pueda ser de utilidad a los industriales del Sector de la Piedra Natural Debido a la extensión del trabajo, se ha dividido en dos partes: en esta primera se analiza la influencia de los factores propios del sistema de corte (maquinaria, discos, características del corte, etc.), y en la segunda parte, en un próximo número de esta revista, se hará hincapié en las características propias de la roca que influyen en su cortabilidad y, por tanto, en el rendimiento de los útiles diamantados.

Abstract: This paper follows another one published in the preceding number of this same journal, that reviewed some scientific papers on the influence of the factors of the cutting equipments (machinery, cutting characteristics, disks, etc) on the efficiency of the cutting process of ornamental rocks with diamond disks. In this second part, the inner rock characteristics (mineralogy, texture and voids) affecting the cutting performance are considered. Some rock classifications based on their cuttability proposed by some authors and Institutions are also reviewed. Este trabajo es continuación de otro ya publicado en un número anterior de esta revista, en el que se revisaban algunos trabajos científicos sobre la influencia de los factores propios del sistema de corte (sierra, parámetros de corte, características del disco, etc.) en el rendimiento del proceso de corte de rocas ornamentales con discos diamantados. En esta segunda parte, se consideran las características propias de la roca (mineralogía, textura y espacios vacíos) que afectan a dicho rendimiento. También se hace una revisión de algunas clasificaciones de rocas (en función de su cortabilidad) propuestas por diversos autores e Instituciones.

Abstract: Computerized axial tomography studies were conducted to analyze water movements inside rocks (specifically in La Marina sandstone, used to build some of the historic monuments in Asturias, northern Spain). The X-ray images of water uptake by the stone interior recorded during capillarity tests provided supplementary information not furnished by conventional methods. The three-dimensional images obtained showed the position of the water front over time and its relationship to rock petrography. The volume of water-soaked rock proved to be a more realistic measure of stone capillarity. The results obtained were compared to mean capillarity measured as recommended in Spanish and European standard UNE-EN 1925:1999. La Tomografía Axial Computerizada de rayos X (TAC) ha sido aplicada al estudio del movimiento del agua en el interior de las rocas, usando como modelo la arenisca de La Marina, roca utilizada en la construcción de algunos monumentos históricos en Asturias (norte de Espa a). Durante los ensayos de capilaridad se han registrado las imágenes de rayos X de la penetración del agua en el interior de la roca que suministran información no aportada por los métodos habituales. La reconstrucción tridimensional muestra la posición del frente de agua a lo largo del tiempo y su relación con las características petrográficas de la roca. La cuantificación del porcentaje en volumen de roca embebida en agua es una medida más real de la capilaridad de la misma. Los resultados así obtenidos han sido comparados con los de la capilaridad medida por el método descrito en la norma UNE-EN 1925:1999.

Abstract: One of the consequences of an aging European society is that there will be fewer ac-tive workers and dependents, so it should be noted, firstly, the importance of workers not to re-tire early and on the other hand, the negative result that employment rates of workers aged 55 to 64 years represent not even 50%. Our goal is to demonstrate the benefit that would represent or the whole society to promote policies that stimulate the permanence in the workplace for older workers, for which we made a tour of European policies aimed at this purpose in recent years.

Abstract: vacuolar atpases (v-atpases) are present in specialized proton secretory cells in which they pump protons across the membranes of various intracellular organelles and across the plasma membrane. the proton transport mechanism is electrogenic and establishes an acidic ph and a positive transmembrane potential in these intracellular and extracellular compartments. v-atpases have been found to be practically identical in terms of the composition of their subunits in all eukaryotic cells. they have two distinct structures: a peripheral catalytic sector (v1) and a hydrophobic membrane sector (v0) responsible for driving protons. v-atpase activity is regulated by three different mechanisms, which control pump density, association/dissociation of the v1 and v0 domains, and secretory activity. the c subunit is a 40-kda protein located in the v1 domain of v-atpase. the protein is encoded by the atp6v1c gene and is located at position 22 of the long arm of chromosome 8 (8q22.3). the c subunit has very important functions in terms of controlling the regulation of the reversible dissociation of v-atpases.
