Noticias de ataques y destrucciones en Orihuela durante el período andalusí (ss. VIII-XIII)

Tras resumirse "Los elementos esenciales de la trama urbana de Orihuela", se estudian los principales hechos históricos durante el período islámico de la ciudad de Orihuela "s. VIII-XIII) en que hay noticia de ataques militares a la ciudad y destrucciones : El ataque de los normandos a Orihuela en 245 H ./859 e.C.; Aceifa del califa ‘Abd al-Raḥmān III al-Nāṣir contra Orihuela y sus rebeldes; La "fitnat al-barbar" o guerra civil que acabó con el califato andalusí; El terremoto posterior a 440 H/1048-9 e.C. que asoló toda la vega del río Segura y finalmente la conquista cristiana de Orihuela. Como conclusiones para el estudio del urbanismo musulmán de Orihuela se demuestra que solo hubo destrucciones en el trazado urbano de importancia como resultado del mencionado terremoto que asoló y destruyó las ciudades de Murcia, Orihuela y toda la Vega Baja del río Segura.

Teaching-learning process of historical heritage: a Journey as a beginning, path and end

The implantation of new university degrees within the European Higher Education Area implies the need of innovative methodologies in teaching and learning to improve the skills and competencies of students and to answer the growing needs that society continuously demands to heritage management experts. The present work shows an application of the teaching methodology proposed during the international workshop entitled “I International Planning Preservation Workshop. Learning from Al Andalus”, which included the participation of the University of Alicante and Granada, Università Politecnico di Milano and Hunter College City University of New York; where we tried to dissolve traditional boundaries derived of interuniversity cooperation programs. The main objective of the workshop was to discuss and debate the role of urban Historical Centers within the Global Heritage by the integrated work through multidisciplinary teams and the creation of a permanent international working group between these universities to both teach and research. The methodology of this workshop was very participatory and considered the idea of a new learning process generated by "a journey experience." A trip from global to local (from the big city to the small village) but also a trip from the local (historical) part of a big city to the global dimension of contemporary historical villages identified by the students through a system of exhibition panels in affinity groups, specific projects proposed by lecturers and teachers or the generation of publications in various areas (texts, photographs, videos, etc.). So, the participation of the students in this multidisciplinary meeting has enhanced their capacity for self-criticism in several disciplines and has promoted their ability to perform learning and research strategies in an autonomous way. As a result, it has been established a permanent international work structure for the development of projects of the Historical City. This relationship has generated the publication of several books whose contents have reflected the conclusions developed in the workshop and several teaching proposals shared between those institutions. All these aspects have generated a new way of understanding the teaching process through a journey, in order to study the representative role of university in the historical heritage and to make students (from planning, heritage management, architecture, geography, sociology, history or engineering areas) be compromised on searching strategies for sustainable development in the Contemporary City.

How to name new chemical elements (IUPAC Recommendations 2016)

A procedure is proposed to name new chemical elements. After the discovery of a new element is established by the joint IUPAC-IUPAP Working Group, the discoverers are invited to propose a name and a symbol to the IUPAC Inorganic Chemistry Division. Elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist. After examination and acceptance by the Inorganic Chemistry Division, the proposal follows the accepted IUPAC procedure and is then ratified by the Council of IUPAC. This document is a slightly amended version of the 2002 IUPAC Recommendations; the most important change is that the names of all new elements should have an ending that reflects and maintains historical and chemical consistency. This would be in general “-ium” for elements belonging to groups 1–16, i.e. including the f-block elements, “-ine” for elements of group 17 and “-on” for elements of group 18.
