Development of the BG-Malaria trap as an alternative to human-landing catches for the capture of Anopheles darlingi

Although the human-landing catch (HLC) method is the most effective for collecting anthropophilic anophelines, it has been increasingly abandoned, primarily for ethical considerations. The objective of the present study was to develop a new trap for the collection of Anopheles darlingi . The initial trials were conducted using the BG-Sentinel trap as a standard for further trap development based on colour, airflow direction and illumination. The performance of the trap was then compared with those of the CDC, Fay-Prince, counterflow geometry trap (CFG) and HLC. All trials were conducted outdoors between 06:00 pm-08:00 pm. Female specimens of An. darlingi were dissected to determine their parity. A total of 8,334 anophelines were captured, of which 4,945 were identified as An. darlingi . The best trap configuration was an all-white version, with an upward airflow and no required light source. This configuration was subsequently named BG-Malaria (BGM). The BGM captured significantly more anophelines than any of the other traps tested and was similar to HLC with respect to the number and parity of anophelines. The BGM trap can be used as an alternative to HLC for collecting anophelines.

Metodología de simulación del almacenamiento geológico de CO2 como contribución a la solución al problema del Cambio Climático, aplicada a la estructura BG-GE-08 (oeste de la Comunidad de Murcia)

Una de las medidas de mitigación del Cambio Climático propuestas al amparo de la ONU por el IPCC (Intergovermental Panel on Climate Change) en su ‘Informe de Síntesis 2007’ consiste en la puesta en marcha de acciones para la captación y almacenamiento de dióxido de carbono, existiendo tres tipos de formaciones geológicas idóneas para el almacenamiento geológico de este gas: yacimientos de petróleo y gas agotados, capas de carbón no explotables y formaciones salinas profundas. En el caso de las formaciones salinas profundas, el problema fundamental para llevar a cabo un estudio de almacenamiento de CO2, reside en la dificultad de obtención de datos geológicos del subsuelo en una cierta estructura seleccionada, cuyas características pueden ser a priori idóneas para la inyección y almacenamiento del gas. Por este motivo la solución para poder analizar la viabilidad de un proyecto de almacenamiento en una estructura geológica pasa por la simulación numérica a partir de la modelización 3D del yacimiento. Los métodos numéricos permiten simular la inyección de un caudal determinado de dióxido de carbono desde un pozo de inyección localizado en una formación salina. En la presente tesis se ha definido una metodología de simulación de almacenamiento geológico de CO2, como contribución a la solución al problema del Cambio Climático, aplicada de forma concreta a la estructura BG-GE-08 (oeste de la Comunidad de Murcia). Esta estructura geológica ha sido catalogada por el IGME (Instituto Geológico y Minero de España) como idónea para el almacenamiento de dióxido de carbono, dada la existencia de una capa almacén confinada entre dos capas sello. ABSTRACT One of the climate change mitigation proposals suggested by the IPCC (Intergovermental Panel on Climate Change) in its ‘Synthesis Report 2007’ involves the launch of actions for capturing and storing carbon dioxide, existing three different geological structures suitable for gas storage: oil and gas reservoirs already drained, useless coal layers and deep saline structures. In case of deep saline structures, the main problem to develop a study of CO2 storage is the difficulty of obtaining geological data for some selected structure with characteristics that could be suitable for injection and gas storage. According to this situation, the solution to analyze the feasibility of a storage project in a geological structure will need numerical simulation from a 3D model. Numerical methods allow the simulation of the carbon dioxide filling in saline structures from a well, used to inject gas with a particular flow. In this document a simulation methodology has been defined for geological CO2 storage, as a contribution to solve the Climatic Change problem, applied to the structure BG-GE-08 (west of Murcia region). This geological structure has been classified by the IGME (Geological and Mining Institute of Spain) as suitable for the storage of carbon dioxide given the existence of a storage layer confined between two seal layers.

A code for direct numerical simulation of turbulent boundary layers at high Reynolds numbers in BG/P supercomputers

A new high-resolution code for the direct numerical simulation of a zero pressure gradient turbulent boundary layers over a flat plate has been developed. Its purpose is to simulate a wide range of Reynolds numbers from Reθ = 300 to 6800 while showing a linear weak scaling up to 32,768 cores in the BG/P architecture. Special attention has been paid to the generation of proper inflow boundary conditions. The results are in good agreement with existing numerical and experimental data sets.
