    The Guipuzcoans participated with their militias and their armed men in the war against Granada waged by the Catholic Monarchs Isabella and Ferdinand, from their ascension to the throne of the Crown of Castile to the conquest of the Muslim kingdom of Granada in 1492. In this paper we look into how several requests were made from the Province of Guipuzcoa for several ships with their respective armed crews in order to control the different points of access to the Strait of Gibraltar, on the one hand, and, on the other hand, we examine the replies given by the representatives of the Province councils after the Board Meeting at Usarraga.Los guipuzcoanos participaron con sus milicias y hombres armados en la Guerra de Granada auspiciada por los Reyes Católicos, Isabel y Fernando, desde su ascenso al trono de la Corona de Castilla hasta la conquista del reino nazarí en 1492. En este artículo se estudian por una parte las demandas a la Provincia Guipúzcoa de varias embarcaciones con sus respectivas tripulaciones armadas para controlar los accesos a Granada a través del Estrecho de Gibraltar y por otra las diversas respuestas dadas por los procuradores generales de los concejos de la Provincia, reunidos en la Junta General de Usarraga

    Despite continuous progress in X-ray angiography systems, X-ray coronary angiography is fundamentally limited by its 2D representation of moving coronary arterial trees, which can negatively impact assessment of coronary artery disease and guidance of percutaneous coronary intervention. To provide clinicians with 3D/3D+time information of coronary arteries, methods computing reconstructions of coronary arteries from X-ray angiography are required. Because of several aspects (e.g. cardiac and respiratory motion, type of X-ray system), reconstruction from X-ray coronary angiography has led to vast amount of research and it still remains as a challenging and dynamic research area. In this paper, we review the state-of-the-art approaches on reconstruction of high-contrast coronary arteries from X-ray angiography. We mainly focus on the theoretical features in model-based (modelling) and tomographic reconstruction of coronary arteries, and discuss the evaluation strategies. We also discuss the potential role of reconstructions in clinical decision making and interventional guidance, and highlight areas for future research
