3D-Reconstruction of a Giant Posidonia oceanica Beach Wrack (Banquette): Sizing Biomass, Carbon and Nutrient Stocks by Combining Field Data With High…

2022

Beach wracks are temporary accumulations of vegetal detritus that can be found along coastlines all over the world. Although beach wracks are often perceived as a nuisance for beach users, they play a crucial ecological role in carbon and nutrient connectivity across ecosystem boundaries, especially when they reach a relevant size, as in the case of the wedge-shaped seagrass accumulations called banquette. In this study, three-dimensional mapping of a giant Posidonia oceanica banquette was carried out for the first time using high-resolution UAV photogrammetry combined with field sampling and compositional and chemical analysis. The combined approach allowed a reliable estimation of the amo…

Mejora de la calidad de vida del residente a través de estrategias de marketing: Un análisis comparado entre México y España.

2015

Los gobiernos locales hoy en día deben desarrollarse y crecer igual que las grandes empresas existentes en el mundo. Para ello, deben gestionar y administrar sus territorios geográficos como si de una marca se tratara. En este tenor, la actitud hacia la marca-ciudad favorece la creación de actitudes positivas hacia la sostenibilidad. En este marco, la presente tesis persigue los cinco objetivos siguientes: (i) Abordar el papel del marketing experiencial basado en mega-eventos para construir, tanto actitud hacia la marca-ciudad como hacia la sostenibilidad. (ii) Abordar el papel del marketing verde (orientación ecológica) para construir, tanto actitud hacia la marca-ciudad como hacia la sost…

Toxic megacolon and human Cytomegalovirus in a series of severe ulcerative colitis patients

2015

Abstract Background Human Cytomegalovirus (HCMV) infection has been reported to be a cause of refractory ulcerative colitis (UC). Toxic megacolon (TM) is a rare but severe complication of an acute attack of UC. Objectives Aim of this study is to evaluate in a case-control study the association between HCMV and TM. Study design All patients who were admitted at Medicine Department of V. Cervello Hospital in Palermo (tertiary referral center) for a severe UC flare-up complicated by the onset of TM (diameter of the transverse colon > 6 cm) between January 1990 and November 2011 were identified through the electronic database. A total of 24 consecutive patients (16 male/8 female) with TM were i…

2016

Abstract The fruit and fruit juice of 30 accessions of cactus pear (23 accessions of Opuntia ficus indica and 7 accessions of Opuntia megacantha ) grown in different regions of Morocco were analyzed. The morphological characteristics of the fruit and the pH, titratable acidity, contents of soluble solids, total carotenoids, reducing sugars, and vitamin C in the fruit juice were analyzed. Fruit length, fresh fruit weight, fresh skin weight, fresh skin to fruit ratio, dry skin weight, and water content in the skin varied significantly within and between the two species. There were significant differences among accessions in most of the fruit juice characteristics. The ranges of measured value…

Surface Micro Discharge–Cold Atmospheric Pressure Plasma Processing of Common House Cricket Acheta domesticus Powder: Antimicrobial Potential and Lip…

2021

The growing world population and the need to reduce the environmental impact of food production drive the exploration of novel protein sources. Insects are being cultivated, harvested, and processed to be applied in animal and human nutrition. The inherent microbial contamination of insect matrices requires risk management and decontamination strategies. Thermal sterilization results in unfavorable cooking effects and oxidation of fatty acids. The present study demonstrates the risk management in Acheta domesticus (home cricket) powder with a low-energy (8.7–22.0 mW/cm2, 5 min) semi-direct surface micro discharge (SMD)–cold atmospheric pressure plasma (CAPP). At a plasma power density lower…

Three Amadisian Poems by Pere Gimferrer, José Manuel Lucía Megías and Luis Alberto de Cuenca

2020

Análisis literario de las representaciones de Urganda la Desconocida en textos poéticos de Luis Alberto de Cuenca, Pere Gimferrer y José Manuel Lucía Megías, publicados a partir de 1985. La Desconocida es uno de los seres sobre-naturales más originales de las letras hispánicas. El sincretismo que revelan sus orígenes sufrió una profunda revisión a lo largo del Amadís de Gaula, de Garci Rodríguez de Montalvo, factor que redundó en su importancia en el imagi-nario literario del siglo XVI. De la mano de tres de los poetas que mejor conocen la tradición literaria del Medioevo, se valorarán las significaciones éticas y estéticas de esta insólita resurrección poética, muy diferente en cada uno de…

An automated image analysis methodology for classifying megakaryocytes in chronic myeloproliferative disorders

2008

This work describes an automatic method for discrimination in microphotographs between normal and pathological human megakaryocytes and between two kinds of disorders of these cells. A segmentation procedure has been developed, mainly based on mathematical morphology and wavelet transform, to isolate the cells. The features of each megakaryocyte (e.g. area, perimeter and tortuosity of the cell and its nucleus, and shape complexity via elliptic Fourier transform) are used by a regression tree procedure applied twice: the first time to find the set of normal megakaryocytes and the second to distinguish between the pathologies. The output of our classifier has been compared to the interpretati…

An Improved Solver for the M/EEG Forward Problem

2014

Noninvasive investigation of the brain activity via electroencephalography (EEG) and magnetoencephalography (MEG) involves a typical inverse problem whose solution process requires an accurate and fast forward solver. We propose the Method of Fundamental Solutions (MFS) as a truly meshfree alternative to the Boundary Element Method (BEM) for solving the M/EEG forward problem. The solution of the forward problem is obtained, via the Method of Particular Solutions (MPS), by numerically solving a set of coupled boundary value problems for the 3D Laplace equation. Numerical accuracy and computational load are investigated for spherical geometries and comparisons with a state-of-the-art BEM solv…
