Optimizing electron backscatter diffraction of carbonate biominerals—resin type and carbon coating

Electron backscatter diffraction (EBSD) is becoming a widely used technique to determine crystallographic orientation in biogenic carbonates. Despite this use, there is little information available on preparation for the analysis of biogenic carbonates. EBSD data are compared for biogenic aragonite and calcite in the common blue mussel, <i>Mytilus edulis</i>, using different types of resin and thicknesses of carbon coating. Results indicate that carbonate biomineral samples provide better EBSD results if they are embedded in resin, particularly epoxy resin. A uniform layer of carbon of 2.5 nm thickness provides sufficient conductivity for EBSD analyses of such insulators to avoid charging without masking the diffracted signal. Diffraction intensity decreases with carbon coating thickness of 5 nm or more. This study demonstrates the importance of optimizing sample preparation for EBSD analyses of insulators such as carbonate biominerals

Biogas Power Energy Production from a Life Cycle Thinking

The purpose of this chapter is to present a generalized model for the construction of inventories for the production of electricity through biogas. This general framework can be adjusted to any power plant that uses biogas, since it complies with the main material and energy balances. This chapter describes the main technologies used in biogas power energy production, separating them into five main subsystems that integrate the general life cycle inventory, as well as the inputs and outputs considered in the development of the inventories. The life cycle assessment (LCA) of two types of plants is presented as study cases: (i) the biogas power energy generation with organic waste in landfills as substrate and (ii) the biogas power energy generation using dairy cattle manure as substrate. Both systems, in addition to using different types of substrate, present differences in their substages. It is concluded that the generation of studies of life cycle analysis of technologies facilitates decision makers, producers, and government agencies to develop and identify areas of opportunity from life cycle thinking

Development of an open sensorized platform in a smart agriculture context: A vineyard support system for monitoring mildew disease

In recent years, some offcial reports, to produce best products regarding quality, quantity and economic conditions, recommend that the farming sector should benefit with new tools and techniques coming from Information and Communications Technology (ICT) realm. In this way, during last decade the deployment of sensing devices has increased considerably in the field of agriculture. This fact has led to a new concept called smart agriculture, and it contemplates activities such as field monitoring, which offer support to make decisions or perform actions, such as irrigation or fertilization. Apart from sensing devices, which use the Internet protocol to transfer data (Internet of Things), there are the so-called crop models, which are able to provide added value over the data provided by the sensors, with the aim of providing recommendations to farmers in decision-making and thus, increase the quality and quantity of their production. In this scenario, the current work uses a low-cost sensorized platform, capable of monitoring meteorological phenomena following the Internet of Things paradigm, with the goal to apply an alert disease model on the cultivation of the vine. The edge computing paradigm is used to achieve this objective; also our work follows some advances from GIScience to increase interoperability. An example of this platform has been deployed in a vineyard parcel located in the municipality of Vilafamés (Castelló, Spain)

Selección de Características de Microarreglos de ADN Utilizando una Búsqueda Cuckoo

En este artículo, se propone un método híbrido para la selección y clasificación de datos de microarreglos de AND. Primero, el método combina los subconjuntos de genes relevantes obtenidos de cinco métodos de filtro, después, se implementa un algoritmo basado en una búsqueda cuckoo combinado con un clasificador MSV. El algoritmo híbrido explora dentro del subconjunto obtenido en la etapa anterior y selecciona los genes que alcanzan un alto desempeño al entrenar al clasificador. En los resultados experimentales, el algoritmo obtiene una tasa de clasificación alta seleccionado un número pequeño de genes, los resultados obtenidos son comparados con otros métodos reportados en la literatura

Intimidación y maltrato en una muestra de niños

The aim was prevention of bullying and abuse in a sample of children basic level. We worked with 13 boys and 10 girls, 8 to 10 years, from a public elementary school. The results showed that sociability was improved visibly reducing school violence.Keywords: resilience, school violence, prevention of abuse, intimidationEl objetivo fue la prevención de la intimidación y el maltrato en una muestra de niños de nivel básico.

Leading Interview and Interrogation Techniques. Focus on Cognitive Interview

Criminal investigation in Mexico is performed by the investigation triad, which is made up of police and experts in diff erent areas such as medicine and prosecutors. They all use interview and interrogation techniques to do their work. Unfortunately, in Mexico, there is no culture of training in governmental institutions responsible for investigating crimes, and results in ignorance of techniques for obtaining objective and reliable information that guarantees the protection of fundamental rights. This chapter illustrates the scope and limits of interview and interrogation techniques and their objectives, with emphasis on the cognitive interview (CI). Th e CI, which has been validated scientifi cally, is one of the best tools to obtain useful information, that is, results of a CI that have been conducted in the field can be used in a court of law. Th is technique can be used with victims, witnesses, or suspects. The current chapter also describes the most utilized techniques, cognitive interview, mnemonic techniques, Strategic Use of Evidence, and Verifi ability Approach

ARCHITECTURE WITHOUT PLANS; ‘LA PETATERA’ BULLRING

[EN] La Petatera is a bullring which is installed each January and dismantled at the end of February. Its name comes from the petates - strips of material - which cover a structure of otates - poles - made of guadua and different types of wood from the area. There is no known original grand plan for the Petatera. The oldest remaining drawing is a sketch of the outline drawn into the earth. If the ‘project’ is superfluous, then the scrupulous repetition of the construction process is essential because this is the only way to guarantee the success of the final product. In the Petatera the architectural value goes from the object to the ritual, and from the building to the method of construction.[ES] La Petatera es una plaza de toros que se instala cada enero desmontándose a finales de febrero. Su nombre proviene de los petates o esteras, que recubren una estructura de otates de guadua y maderas de la zona. No se conocen planos originales de La Petatera. El dibujo más antiguo conservado es un esquema de replanteo. Si la previa representación gráfica, el proyecto, resulta superflua, sin embargo, la escrupulosa repetición de los procesos constructivos es esencial para garantizar la idoneidad del resultado. En La Petatera el valor arquitectónico se desplaza del objeto al rito, y de la obra a la construcción.Calduch Cervera, J.; Elizondo Mata, MF.; Mendoza Pérez, LA.; González De Loza, JR.; Huerta Sanmiguel, R.
