The palm tree in the landscape of the Bajo Segura basin irrigated area. An identity element in need of protection

La palmera, como aprovechamiento agrícola, ha estado estrechamente vinculada al espacio de la Huerta generado a lo largo de los siglos en la llanura aluvial del Segura. Los múltiples usos derivados de ésta han fortalecido su permanencia, a la vez que la imagen identitaria con que se asocia al territorio. Su presencia ha quedado plasmada en escritos de todo tipo desde la Ilustración hasta nuestros días, lo que permite contrastar la visión de entonces con la situación que atraviesa en la actualidad. Para ello se analizan tres ámbitos diferentes, San Isidro, una población entre palmeras tras la colonización de suelos salinos; el Palmeral de Orihuela, como pervivencia de un enclave histórico ligado a los rendimientos mixtos de la tierra; y finalmente, la dispersión generalizada de la palmera por el medio agrario.The palm tree, regarded as an agrarian resource, has been closely linked to the orchards, or spaces of "Huerta", developed over centuries in the Segura River fertile plains. The multiple uses of the palm tree have guaranteed its continuity and strengthened its association with the identity image related to this territory. Its presence has been captured in all types of written documents, from the Enlightenment to recent times, allowing us to compare ancient vision and present situation. To develop this comparison the paper analyses three different contexts: San Isidro, a town built between palms previously planted on saline soil, the Palmeral of Orihuela, a survival remain of a historic site associated with mixed cultivation of land and, finally, the generalized palm tree dispersion through the agrarian landscape

The palm tree, an identity-defining element in the Huerta landscape of Bajo Segura (SE of Spain)

La palmera, por sus múltiples aprovechamientos (agrícola, constructivo, ritual e industrial), ha sido tradicionalmente un elemento identitario en el paisaje huertano del Bajo Segura. En las últimas décadas su presencia se ha restringido, al perder las funciones que antaño cumplía, a lo que se ha unido la plaga del picudo rojo y la comercialización masiva con fines ornamentales para las nuevas áreas residenciales. El artículo aborda la presencia de esta especie en el territorio desde diversas visiones y en diferentes épocas: la estética de la literatura de viajes, la productiva de los tratados científicos o la emocional de las obras de creación.The palm tree, because of its numerous uses (agricultural, constructive, ritual and industrial), has been traditionally an identity-defining element in the landscape of the Bajo Segura irrigated area (SE of Spain). In recent decades, its presence has been limited, by the loss of functions that palm tree previously carried out, currently joined to the red palm weevil pest (Rhynchophorus ferrugineus) and the massive sale with ornamental purposes in the new built-up areas emerged from residential tourism boom. This article deals with the presence of the Palm in the territory from several views and in different times: the aesthetic of travel literature, the productive of scientific reports or the emotional of artistic works

Nonlinear Observability Algorithms with Known and Unknown Inputs: Analysis and Implementation

The observability of a dynamical system is affected by the presence of external inputs, either known (such as control actions) or unknown (disturbances). Inputs of unknown magnitude are especially detrimental for observability, and they also complicate its analysis. Hence, the availability of computational tools capable of analysing the observability of nonlinear systems with unknown inputs has been limited until lately. Two symbolic algorithms based on differential geometry, ORC-DF and FISPO, have been recently proposed for this task, but their critical analysis and comparison is still lacking. Here we perform an analytical comparison of both algorithms and evaluate their performance on a set of problems, while discussing their strengths and limitations. Additionally, we use these analyses to provide insights about certain aspects of the relationship between inputs and observability. We found that, while ORC-DF and FISPO follow a similar approach, they differ in key aspects that can have a substantial influence on their applicability and computational cost. The FISPO algorithm is more generally applicable, since it can analyse any nonlinear ODE model. The ORC-DF algorithm analyses models that are affine in the inputs, and if those models have known inputs it is sometimes more efficient. Thus, the optimal choice of a method depends on the characteristics of the problem under consideration. To facilitate the use of both algorithms, we implemented the ORC-DF condition in a new version of STRIKE-GOLDD, a MATLAB toolbox for structural identifiability and observability analysis. Since this software tool already had an implementation of the FISPO algorithm, the new release allows modellers and model users the convenience of choosing between different algorithms in a single tool, without changing the coding of their modelThis research was supported by the Spanish Ministry of Science, Innovation and Universities through the project SYNBIOCONTROL (reference DPI2017-82896-C2-2-R).

El desarrollo turístico de Orihuela y su incidencia en el poblamiento (1910-2010)

The century 1910-2010 represents to Orihuela municipality (SE of Spain) a momentous change that is reflected both in social aspects as in economic. Agriculture, the most determinant factor on wealth, has been pushed into the background in favour of the secondary and tertiary sectors. In this process, tourism has generated an alteration in the traditional distribution of population, which has caused the current antagonism that exists between interior lands and the coast. A group of foreign residents has been encouraged by this urban duality reaching 42,2% of total municipality population.La centuria de 1910 a 2010 representa para el municipio de Orihuela un cambio trascendental que se refleja tanto en los aspectos sociales como económicos. La agricultura, factor condicionante de la riqueza, ha quedado relegada frente a los sectores secundario y terciario. En este proceso, el turismo ha generado una alteración en la tradicional distribución del poblamiento que origina el antagonismo actual entre el interior y la costa. Esta dualidad urbana está motivada por la presencia de un colectivo de residentes extranjeros que alcanza el 42,2% de la población municipal

El medio de carga incorpora dos guías curvas (1a, 1b) colocadas de forma simétrica y cuyas caras exteriores definen sendas pistas de rodadura (11a, 11b) sobre las que pueden desplazarse sendos rodillos (3a, 3b). Los ejes (4a, 4b) de dichos rodillos (3a, 3b) están unidos entre sí mediante un resorte de extensión (5). Dos tirantes (6a, 6b) unen los ejes (4a, 4b) de sendos rodillos (3a, 3b) con un cable de carga (8). La geometría de la curva definida por las pistas de rodadura (11a, 11b) es tal que la fuerza exterior aplicada sobre el cable de carga (8) es la misma independientemente de la posición en la que se encuentren los rodillos (3a, 3b).UNIVERSIDAD DE ALMERÍ
