Parametric UAS leg design for atmostpheric structure investigation

Tornadoes are one of the most devastating atmospheric phenomena worldwide. Only in the EEUU, there are more than 1400 tornadoes yearly. Despite the great effort trying to understand and predict the behavior and path of the tornadoes, the truth is that there not exists an accurate model yet. For more than 50 years, it has been summarized the importance of a certain zone of the tornadoes, the Rear-Flank Downdraft (RFD), on tornado genesis and intensification. This zone is well documented, but its dynamic role it is not understood yet. Recently, some experiments has sent RC Unmanned Aircraft (UA) to sample this zone. The research group Icarus has developed an UAS (Unmanned Aircraft System) defined by a sort of services which cooperate together so as the FMS (Flight Management System) being able to fly using a basic waypoint guidance. The whole system and missions have been developed by using reconfigurable parameters that allow dynamic parametrical scans. That is, instead of specifying the complete trajectory of the mission, it is just need to define some parameters. The motivation of this final project degree has been, taking advantage of the possibilities of the parametrical scans of the Icarus research group UAS bring us, to design a new scan type to do a research on RFD environment. This way, enabling the UAS to fly wisely through this part of the tornadoes with the goal of developing a sample strategy to collect the maximum possible in situ data, regarding both the RFD characteristics as well as possible more generic atmospheric applications. Starting from some hypothesis about the needs on this new kind of scans, the Curved Scan has been developed. There has been a parameter discussion and its refinements so as to obtain a robust algorithm. In addition, due to the importance of the quickness of this missions, the sort of traces and how they are linked to each other, a new turn type has been developed -as well as an extension for further applications-. Finally, it has been implemented inside the simulation environment, with particular examples, and it has been shown the applicability of this new scan type in the surveillance with UAS of the volcanic plumes

Satisfacción, conflictos y consecuencias psicológicas en las relaciones de pareja. Una revisión bibliográfica

Treball Final de Grau en Psicologia. Codi: PS1048. Curs acadèmic: 2016/2017En este trabajo se realizó una revisión bibliográfica sobre las principales causas y los distintos conflictos que se ocasionan en las relaciones de pareja, además de identificar los factores de satisfacción de la pareja. Se revisó toda la bibliografía relacionada con las relaciones de pareja, conflictos, satisfacción y consecuencias psicológicas en las distintas bases de datos. Tras la búsqueda se seleccionaron 53 artículos, aquellos que fueron más adecuados para desarrollar la presente revisión. Los estudios muestran que el divorcio aumenta en España y la celebración del matrimonio se está reduciendo, además se observa que las parejas le otorgan gran importancia al compromiso, confianza, expresiones de afecto y el factor económico como principales motivos para que la relación funcione, por otro lado, se destaca que con los conflictos más habituales en las parejas se deben a la infidelidad, celos, insatisfacción sexual, comunicación inefectiva y los distintos criterios en relación a la crianza de los hijos. Las investigaciones muestran que los conflictos entre las parejas pueden ocasionar trastornos mentales como depresión, trastornos de ansiedad, estrés, y conductas adictivas. Con esta revisión se ha planteado la importancia de la terapia de pareja y con ella poder prevenir futuros trastornos mentales, y se debe considerar implantar este tipo de terapia desde atención primaria.In this work a bibliographic review was made on the main causes and the different conflicts that occur in the couple relationships, besides identifying the satisfaction factors of the couple. All the bibliography related to the relations of pair, conflicts, satisfaction and psychological consequences in the different data bases were reviewed. After the research, 53 articles were selected, the most appropriated to carry out the present revision. The recent studies show that the divorce is rapidly growing up in Spain and that the weddings are as well dropping. It has been shown as well that couples give special importance to compromise, trust, affection and the economy as the main objective to make relationship work. On the other hand, it has been shown that the main reason to break down a relationship is unfaithfulness, disaffective communication, sexual dissatisfaction and different criteria in relation rising children. Researches show that the conflicts of the couples may cause mental disorder like depression, anxiety disorders, stress and additive behaviors. The couple’s therapy has been set out and prevent future mental disorders, and this therapy must be considered even from the Primary Care Center

Neutron-induced fission fragment angular distribution and cross section of uranium targets at CERN-n TOF

This thesis work focuses on the measurement of the fission fragment angular distribution (FFAD) and fission cross section of the reactions 234U(n,f) y 235U(n,f) using PPAC (Parallel Plate Avalanche Counter) detectors at the n_ TOF facility (CERN). This faci lity is characterised by a wide neutron spectrum from thermal to 1 GeV with a high energy resolution. This measurement has been performed using the tilted configuration of targets and detectors, which unlike the perpendicular configuration, allows to cover all the emission angles of the fission fragments. Results of the FFAD and the anisotropy parameter have been obtained up to 300 MeV for both reactions, providing for first time data of the 234U(n,f) above 15 MeV and completing the existing measurements of the 235U(n,f). The 235U(n,f) cross section has been obtained up to 100 keV using the neutron flux shape normalised to the IAEA secondary reference. The 234U(n,f) cross section has been calculated in two energy ranges up to 1 GeV using the 235U as reference. The obtained results of the FFAD and the fission cross section are discussed and compared with previous experimental data and with the evaluated librarie

Fission fragment angular distribution measurements of U-235 and U-238 at CERN n_TOF facility

Neutron-induced fission cross sections of U-238 and U-235 are used as standards in the fast neutron region up to 200 MeV. A high accuracy of the standards is relevant to experimentally determine other neutron reaction cross sections. Therefore, the detection efficiency should be corrected by using the angular distribution of the fission fragments (FFAD), which are barely known above 20 MeV. In addition, the angular distribution of the fragments produced in the fission of highly excited and deformed nuclei is an important observable to investigate the nuclear fission process. In order to measure the FFAD of neutron-induced reactions, a fission detection setup based on parallel-plate avalanche counters (PPACs) has been developed and successfully used at the CERN-n_TOF facility. In this work, we present the preliminary results on the analysis of new U-235(n,f) and U-238(n,f) data in the extended energy range up to 200 MeV compared to the existing experimental data.Postprint (published version

An unbiased genetic screen reveals the polygenic nature of the influenza virus anti-interferon response.

Influenza A viruses counteract the cellular innate immune response at several steps, including blocking RIG I-dependent activation of interferon (IFN) transcription, interferon (IFN)-dependent upregulation of IFN-stimulated genes (ISGs), and the activity of various ISG products; the multifunctional NS1 protein is responsible for most of these activities. To determine the importance of other viral genes in the interplay between the virus and the host IFN response, we characterized populations and selected mutants of wild-type viruses selected by passage through non-IFN-responsive cells. We reasoned that, by allowing replication to occur in the absence of the selection pressure exerted by IFN, the virus could mutate at positions that would normally be restricted and could thus find new optimal sequence solutions. Deep sequencing of selected virus populations and individual virus mutants indicated that nonsynonymous mutations occurred at many phylogenetically conserved positions in nearly all virus genes. Most individual mutants selected for further characterization induced IFN and ISGs and were unable to counteract the effects of exogenous IFN, yet only one contained a mutation in NS1. The relevance of these mutations for the virus phenotype was verified by reverse genetics. Of note, several virus mutants expressing intact NS1 proteins exhibited alterations in the M1/M2 proteins and accumulated large amounts of deleted genomic RNAs but nonetheless replicated to high titers. This suggests that the overproduction of IFN inducers by these viruses can override NS1-mediated IFN modulation. Altogether, the results suggest that influenza viruses replicating in IFN-competent cells have tuned their complete genomes to evade the cellular innate immune system and that serial replication in non-IFN-responsive cells allows the virus to relax from these constraints and find a new genome consensus within its sequence space. IMPORTANCE In natural virus infections, the production of interferons leads to an antiviral state in cells that effectively limits virus replication. The interferon response places considerable selection pressure on viruses, and they have evolved a variety of ways to evade it. Although the influenza virus NS1 protein is a powerful interferon antagonist, the contributions of other viral genes to interferon evasion have not been well characterized. Here, we examined the effects of alleviating the selection pressure exerted by interferon by serially passaging influenza viruses in cells unable to respond to interferon. Viruses that grew to high titers had mutations at many normally conserved positions in nearly all genes and were not restricted to the NS1 gene. Our results demonstrate that influenza viruses have fine-tuned their entire genomes to evade the interferon response, and by removing interferon-mediated constraints, viruses can mutate at genome positions normally restricted by the interferon response

Strategic Program Development Practices to Enhance Grassroots 55-65+ Small-sided Football in Diverse International Contexts: The Art, Science and Politics of Implementation

A significant growth in grassroots 55-65+ seniors’ small-sided football (e.g., 3v3, 4v4, 5v5, 6v6/futsal and walking football) programs has emerged in diverse settings on a global scale. Given the ad hoc nature of many program offerings to meet the unique needs and circumstances of older players, very little research has examined strategic program development practices to enhance and sustain participation in seniors’ small-sided football. Strategic program development is a complex and multifaceted process that provides a critical foundation for both quality assurance and quality enhancement. Case study research using multiple-case design suggests that no one size fits all, and that strategic program development draws upon a wide range of iterative and responsive program context, program planning, program leadership/coaching, and program impact assessment strategies to enhance and sustain player participation. This paper provides a conceptual framework and practical examples for strategic program development practices in diverse grassroots 55-65+ small-sided football contexts
