Instrumentation and software for the VERITAS Project and the detection of TeV Gamma-Ray Emission from the BL Lacertae Object 1ES1959+650

Transmission of Cherenkov light through the atmosphere is strongly influenced by the optical clarity of the atmosphere and the prevailing weather conditions. The performance of telescopes measuring this light is therefore dependent on atmospheric effects. This thesis presents software and hardware developed to implement a prototype sky monitoring system for use on the proposed next-generation gamma-ray telescope array, VERITAS. The system, consisting of a CCD camera and a far-infrared pyrometer, was successfully installed and tested on the ten metre atmospheric Cherenkov imaging telescope operated by the VERITAS Collaboration at the F.L. Whipple Observatory in Arizona. The thesis also presents the results of observations of the BL Lacertae object, 1ES1959+650, made with the Whipple ten metre telescope. The observations provide evidence for TeV gamma-ray emission from the BL Lacertae object, 1ES1959+650, at a level of more than 15 standard deviations above background. This represents the first unequivocal detection of this object at TeV energies, making it only the third extragalactic source seen at such levels of significance in this energy range. The flux variability of the source on a number of timescales is also investigated.

The Catalan countries project (1931-1939)

In the evolution of Catalan nationalism, as much politician as cultural, the period of II Spanish Republic (1931-1939) was essential. The obtaining of the Statute of Autonomy (1931-1932) supposed the beginning of a stage of expansion in multiple aspects. One of them were the contacts with the Catalanists nuclei of the rest of the cultural space of Catalan language in which, at that time, it would begin to call Catalan Countries (Balearic Islands, Valencian Country, Andorra, Rosselló, to l'Alguer). On Those Collaborations between cultural organizations, political and particular parties Catalonia always will be the model to follow. The Increasing connections will be visualized on press, as well as on cultural celebrations, policy of parties and Constituent Courts. This evolution will be cut by the Franco victory in the Civil War in 1939.

Processos participatius, governança ambiental i desenvolupament territorial sostenible

Estudio realizado a partir de una estancia en el Centro de Filosofia e Ciências Humanas de la Universidade Federal de Santa Catarina, Brasil, durant entre septiembre y noviembre del 2005. El intercambio con los grupos de trabajo del Programa de Pós-Graduçao Interdisciplinar em Ciências Humanas (UFSCE-Brasil), se ha llevado a cabo con el objetivo de profundizar en las diferentes perspectivas teóricas y analíticas que orientan la reflexión sobre el papel crítico de los investigadores en el área de sociología del conocimiento ambiental científico. Esto ha permitido conocer experiencias-laboratorios de procesos participativos para planear intervenciones en áreas protegidas. Estas orientaciones conceptuales, epistemológicas y metodológicas ayudaran a la candidata a reforzar la aproximación de investigación participativa del proyecto “Avaluació social multicriteri per a la presa de decisions orientades a una gestió conservativa de sistemes agropecuaris i el desenvolupament sostenible de la zona seca i semi-seca del paisatge terrestre protegit de Miraflor-Moropotente (Nicaragua)” que es la línea del trabajo de PhD de la candidata. En especial, las reflexiones teóricas y metodológicas se han centrado en los siguientes temas: aproximación sistemática y basada en los actores para el análisis de sistemas complejos y incertezas, métodos participativos para las evaluaciones integradas de sustentabilidad que apoyan los procesos de toma de decisiones, o el nuevo papel de los investigadores sobre una perspectiva compleja de análisis y diálogo entre los conocimientos científicos y locales.

Transferring QTL technology to the pig breeding industry (PigQTech) - a demonstration project

The aim of the project has been to demonstrate how the farm animal breeding industry can utilise gene mapping technology to accelerate genetic improvement. Previous theoretical studies had suggested that the use of marker assisted selection could potentially increase the annual improvement for quantitative traits like backfat with about 10% and for more difficult traits such as meat quality and reproduction by as much as 40-60% compared with existing technology. The work has comprised two major tasks: 1. Commercially relevant populations have been screened for segregation at QTLs identified in experimental populations. The aim has been to establish optimal strategies for QTL detection in commercial pig populations and the extent to which QTLs explaining major phenotypic differences between divergent lines used in experimental studies also explain quantitative variation within commercial lines. The results are important for specifying future strategies for finding economically valuable QTLs. 2. Marker assisted backcrossing has been used to demonstrate how a QTL allele can be introgressed from one breed to another. The work has focused on the major fatness QTL on pig chromosome 4 previously identified in a wild pig/Large White intercross. The end result was not designed to be a commercially viable product in its own right, but the process has validated a number of points of major importance for the exploitation of QTLs in livestock.

Historic evolution and urban planning typology of Olympic Village

Article providing a broad historical overview of the role and typology of Olympic villages along the history of the Modern Olympic Games. This article was published in the book entitled ‘Olympic Villages: a hundred years of urban planning and shared experiences’ compiling the papers given at the 1997 International Symposium on International Chair in Olympism (IOC-UAB).

Inequality and a repeated joint project

Agents voluntarily contribute to an infinitely repeated joint project. We investigate the conditions for cooperation to be a renegotiation-proof and coalition-proof equilibrium before examining the influence of output share inequality on the sustainability of cooperation. When shares are not equally distributed, cooperation requires agents to be more patient than under perfect equality. Beyond a certain degree of share inequality, full efficiency cannot be reached without redistribution. This model also explains the coexistence of one cooperating and one free-riding coalition. In this case, increasing inequality can have a positive or negative impact on the aggregate level of effort.

Behind the Scenes of an Ant Genome Project

Dramatic improvements in DNA sequencing technologies have led to amore than 1,000-fold reduction in sequencing costs over the past five years.Genome-wide research approaches can thus now be applied beyond medicallyrelevant questions to examine the molecular-genetic basis of behavior,development and unique life histories in almost any organism. A first step foran emerging model organism is usually establishing a reference genomesequence. I offer insight gained from the fire ant genome project. First, I detailhow the project came to be and how sequencing, assembly and annotationstrategies were chosen. Subsequently, I describe some of the issues linked toworking with data from recently sequenced genomes. Finally, I discuss anapproach undertaken in a follow-up project based on the fire ant genomesequence.

Avaluació de l'aprofitament de biomassa disponible per a la producció d'energia calorífica al Parc Natural de l'Alt Pirineu

En aquest article es resumeixen els resultats més destacats del projecte dut a terme pel grup Projecte Biomassa. Aquest estudi té per objectiu l’avaluació de la viabilitat energètica, econòmica i ambiental de l’aprofitament de la biomassa forestal com a recurs energètic a les forests d’Arestui, Baiasca, Montenartró i Virós situades dins el Parc Natural de l’Alt Pirineu (PNAP). En el projecte s’ha fet una revisió dels Plans d’Ordenació Forestal (POF’s) de les esmentades forests per tal d’adequar-les als requeriments del PNAP i així obtenir resultats sobre el potencial de biomassa sosteniblement extraïble, sobre el seu potencial energètic i plantejar un escenari d’aprofitament a mode de cas pràctic. A més a més, s’han realitzat també un balanç socioeconòmic, un balanç d’emissions de CO2 i una avaluació d’impacte ambiental per tal de determinar la viabilitat de l’ús de biomassa al PNAP com a recurs energètic. Com a resultat final s’ha obtingut que el procés d’aprofitament de la biomassa per a la producció d’energia calorífica esdevé una opció de futur viable i positiva ja que la implantació del nou procés comporta beneficis a nivell social, econòmic i ambiental.

The Importance of Revenue Sharing for the Local Economic Impacts of a Renewable Energy Project: A Social Accounting Matrix Approach

As demand for electricity from renewable energy sources grows, there is increasing interest, and public and financial support, for local communities to become involved in the development of renewable energy projects. In the UK, “Community Benefit” payments are the most common financial link between renewable energy projects and local communities. These are “goodwill” payments from the project developer for the community to spend as it wishes. However, if an ownership stake in the renewable energy project were possible, receipts to the local community would potentially be considerably higher. The local economic impacts of these receipts are difficult to quantify using traditional Input-Output techniques, but can be more appropriately handled within a Social Accounting Matrix (SAM) framework where income flows between agents can be traced in detail. We use a SAM for the Shetland Islands to evaluate the potential local economic and employment impact of a large onshore wind energy project proposed for the Islands. Sensitivity analysis is used to show how the local impact varies with: the level of Community Benefit payments; the portion of intermediate inputs being sourced from within the local economy; and the level of any local community ownership of the project. By a substantial margin, local ownership confers the greatest economic impacts for the local community.
