ELARCH Project: Prioritization of threats of cultural heritage for the development of a hazard map. The case study of Aragon’s Castle, Venosa (Italy).

In recent years it has highlighted global interest in disaster prevention and risk mitigation, and the importance of cultural heritage and conservation. According to the literature, the risk is directly linked to two variables: vulnerability and threat, the first related to intrinsic causes of the element and the second to external phenomena. This work is aimed to risk analyses of the Castle of the municipality of Venosa, located in the region of Basilicata (Italy). By studying the threats of the area, based also on historical records of the territory, it has been developed a classification of them, categorized in according to their impact level that could be catastrophic, mild or no harm. Development of threats map by using geographic information systems (GIS) is also discussed

Seismic vulnerability of old Italian fortifications

The damages recorded in the recent seismic events have highlighted that also very robust structures, such as old castles, are vulnerable with respect to not too high seismic actions. However, the damages have allowed not only of understanding the structural behavior of these ancient old fortifications, but also the influence of many factors affecting the specific response. In this paper an overview of the most recent developments in the seismic assessment of Italian medieval castles is presented. The study discusses on the identification of the most vulnerable elements and on their analytical evaluation. Then, an application to an ancient castle chosen as case study is shown

Comparison Among Booth’s and Pekmestzi’s Algorithms for the Multiplication of Two Numbers

A comparison between two different methods of multiplication of two 8-bit numbers is presented. This methods are the Booth’s algorithm and the algorithm proposed by Kiamal Z. Pekmestzi [1]. The general objective is to show the benefits and the advantages obtained if it’s used one of this algorithms over the other. This multipliers have low circuit complexity permitting high-speed operations and the interconnections of the cells are regular. This is the reason why the results shown was obtained using VHDL realization on a FPGA XC4010XL by Xilinx.Consejo de Ciencia y Tecnología del Estado de GuanajuatoConsejo Nacional de Ciencia y TecnologíaUniversidad de GuanajuatoXili

Eco-friendly synthesis of graphene oxide–palladium nanohybrids

Nanostructured hybrids of graphene oxide and palladium were fabricated by means of one-step solvent-free gas phase treatment of graphene oxide with the aliphatic amines 1-octadecylamine and 1,8-diaminooctane, followed by in situ decoration with palladium in the liquid medium using palladium chloride as the precursor and citric acid as a mild and environmentally friendly stabilizing and reducing agent. The proposed synthesis method represents an eco-friendly alternative for obtaining nanohybrids of graphene oxide and palladium nanoparticles under mild conditions. Spectroscopic studies evidenced -COOH group derivatization of graphene due to the amidation reaction; transmission electron microscopy demonstrated the formation of nanometer-sized crystalline palladium particles and evidenced that the diamine-functionalization results in a larger particle sizes than observed for monoamine- or non-functionalized substrates. The hybrids obtained have a slightly lower thermal stability than pristine graphene oxide.</p

Characterization of brush cells of the cerebellum treated by prolonged exposure of the sample to isopropyl alcohol variant of argentic impregnation

Las células cepillo son neuronas glutamatérgicas de la capa granular en la corteza cerebelosa que constan de 3 (tres) o más subtipos, caracterizados por fenotipos químicamente distintos, propiedades intrínsecas para formar sinapsis y patrones de descarga particulares. Dichas células no fueron identificadas por métodos de impregnación argéntica hasta 1994, cuando Mugnaini realiza su descripción. En este trabajo presentamos una variante de impregnación argéntica, en el cual las muestras son sumergidas en alcohol isopropílico y luego sometidas a lavados con alcohol etílico proporcionando un proceso de rápida impregnación que reduce la observación de precipitados, y donde la cristalización se realiza de manera uniforme, lo que permite observar la integridad del cuerpo celular y sus procesos, aumentando tanto la fiabilidad de la técnica como reproducibilidad de la tinción y facilita la toma de sus dimensiones. También se destaca que el medio de montaje influye en la conservación de la calidad temporal del preparado, con una mejora de la preservación utilizando Permount vs bálsamo de Canadá.Brush cells in the cerebellum are glutamatergic neurons of the granular layer. They are divided into three or more subtypes and were not identified by silver impregnation methods until 1994, when Mugnaini identified them using a variant of Golgi method. To make evident brush cells of the Wistar rat cerebellum, we developed a modification of the silver impregnation techniques. The improvement of method is due to the immersion of tissue sections in isopropyl alcohol following sequential washes with ethyl alcohol. It provide a quick impregnation, diminish precipitate outside cells, and the crystallization is more uniform. Morphological and morphometric studies of brush neurons stained with this technique are easy because the cell body and its processes are well observed. We also observed quality differences in the final preparation according with the mounting medium used. An improvement of the preservation was observed using Permount medium.Sociedad de Ciencias Morfológicas de La Plat

LINFEDEMA SECUNDARIO A CÁNCER DE MAMA: ¿UNA POSIBLE SECUELA A CONSIDERAR?

En la actualidad, el cáncer de mama es aún la neoplasia más común entre las mujeres. En años recientes, se ha presentado una evolución importante en el abordaje del tratamiento de esta enfermedad, lo que llevó a considerar que el Linfedema Secundario a Cáncer de Mama (LSCM) era cosa del pasado. Incluso, con  la  incorporación de técnicas como la biopsia selectiva de ganglio centinela se hablaba inicialmente de ausencia de esta secuela, sin embargo, reportes recientes mencionan cifras de LSCM entre 4 y 17 %. Es posible además que la magnitud de LSCM, se esté subestimando, ya que muchas mujeres, a pesar de tener el problema, no buscan atención y además, porque no se cuenta con un método diagnóstico que resulte conveniente, objetivo y estandarizado. La multiplicidad de artículos científicos publicados en el ámbito internacional sobre el tema, evidencían que el LSCM, continua siendo un importante problema a considerar en las sobrevivientes, tanto por su frecuencia, como por el impacto que puede tener en diferentes ámbitos de la vida (físicos, psicológicos y sociales). Es importante además, que se reconozca que las sobrevivientes están a riesgo de por vida de presentarlo y una vez que se ha establecido clínicamente, puede evolucionar hacia la cronicidad, considerándose irreversible, si bien, controlable con el manejo adecuado, lo que implica costos elevados. Lo destacable es que en la actualidad, la investigación, desde prevención, diagnóstico hasta tratamiento está en aumento. En México, la Norma Oficial vigente para  Cáncer de Mama, no incluye el tema de linfedema. Es fundamental, se acepte la posibilidad de su ocurrencia, de entrada, en el ámbito médico, lo que se reflejaría en aportar información hacia las pacientes para que implementen las acciones pertinentes para su prevención y búsqueda de atención oportuna. Abstract Breast cancer is still the most common neoplasy among women. Important changes for its treatment approaches have been observed recently, thinking that Lymphedema Secondary to Breast Cancer (BCRL) was an old issue. Even it was thought that no cases of this sequela would occur with the incorporation of the sentinel lymph node biopsy technique, however, recent reports have shown BCRL rates between 4 – 17%. In addition, it is possible that BCRL is being underestimated, since many women, in spite of having the problem, do not demand medical care, and because of the absence of a convenient, objective and standardized diagnostic method. Many scientific and internationally published articles about this topic rise attention that BCRL is still an important problem to consider among breast cancer survivors, because of its frequency and the impact that it might have on different aspects of life (physical, psychological and social). In addition, it is important to recognize, breast cancer survivors remain at risk of this health problem for lifetime; and once it has clinically settled down, it might become a chronic and irreversible condition, although controllable with the right medical management, which implies higher costs.  A remarkable notice is the increasing research on prevention, diagnosis and treatment of BCRL. In Mexico, current official breast cancer norm, does not include lymphedema as a consequence of this type of cancer. Its possible occurrence must be taken into account at first, among health personnel and eventually, patients should receive this information, for being aware and pertinent actions could be taken for prevention and opportune care. Palabras clave: linfedema, cáncer de mama, secuela
