Drought Management Decision Support System by Means of Risk Analysis Models
2007
Droughts in arid and semiarid Mediterranean river basins have an increasing socioeconomic and environmental impact. The problem is especially complex in basins where droughts are very frequent and intense and where water resources are under a massive use. For that reason in the Mediterranean basins it is necessary to manage the water resources in constant alert in order to relieve the consequences of a drought. In this chapter a complete methodology for the mitigation of the droughts is defined. The methodology includes different tools: from the definition of an alert system for the different types of drought up to the simulation and optimization software for water system management. This m…
Toxic cyanobacterial blooms in reservoirs under a semiarid Mediterranean climate: the magnification of a problem
2007
Sicilian reservoirs constitute the most important water resources available on the island. During summer 2001, the intense water utilization of Lake Arancio reservoir reduced the water level significantly. This coincided with the formation of intense blooms formed by the microcystin-producing cyanobacterium Microcystis aeruginosa. During summer 2003, Lake Arancio was continuously filled and the vertical stratification of the water column was maintained, resulting in 5-6 fold lower cell numbers of Microcystis aeruginosa. For both years a significant linear relationship between microcystin net production and Microcysytis cell division was observed, implying that Microcystis cell numbers can b…
Impact of Initial Soil Temperature Derived from Remote Sensing and Numerical Weather Prediction Datasets on the Simulation of Extreme Heat Events
2016
Extreme heat weather events have received increasing attention and has become of special importance as they can remarkably affect sectors as diverse as public health, energy consumption, water resources, natural biodiversity and agricultural production. In this regard, summer temperatures have become a parameter of essential interest under a framework of a hypothetical increase in the number of intense-heat conditions. Thus, their forecast is a crucial aspect bearing in mind a mitigation of the effects and impacts that these intense-heat situations could produce. The current work tries to reach a better understanding of these sorts of situations that are really common over the Western Medit…
PEDAGOGICAL PROCESS FACILITATING PHYSICAL ACTIVITY OF PRE-SCHOOLERS
2019
The research covers analysis of theoretical literature on significance of physical activities in the development of child’s integrity, as it is a well-known fact that child is researcher and his/her activity is manifested through movement. Child gets his first impressions about surrounding world through movement – the more diverse motions are, the more information is acquired, and the more intense is intellectual development thereof. However, quite often pedagogical process does not consider the specific factors facilitating capacity of child’s physical, functional, motion and mental development. To conduct the research, an aim was set to study physical activity of children in pre-school an…
Skill-Based Scouting of Open Management Content
2010
Already existing open educational resources in management have a high potential for enterprises to address the increasing training needs of their employees. However, access barriers still prevent the full exploitation of this potential. Users have to search a number of repositories with heterogeneous interfaces in order to retrieve the desired content. In addition, the use of search criteria related to skills, such as learning objectives and skill-levels is in most cases not supported. The demonstrator presented in this paper addresses these shortcomings by federating multiple repositories, integrating and enriching their metadata, and employing skill-based search for management related con…
Some Implications for Developing Learners’ Figurative Language Competence Across Modalities: Metaphor, Metonymy and Blending in the Picture Modality
2014
The paper argues for developing learners’ figurative language competence across modalities. Specifically, focusing on the picture modality, the article attempts to show the importance of figurative thinking in the new media age multimodal communication. The sample analysis of pictures and images representing the recent issue of the EU crisis addresses the significance of three conceptual phenomena, namely, metaphor, metonymy, and blending, in the conceptualization of such a highly abstract phenomenon. In general, it is argued that language users almost invariably turn to figurative language resources to conceptualize abstract phenomena that cannot be conceptualized by means of literal langu…
Validación y verificación analítica de los métodos microbiológicos
2015
Clinical microbiologists should ensure, to the maximum level allowed by the scientific and technical development, the reliability of the results. This implies that, in addition to meeting the technical criteria to ensure their validity, they must be performed with a number of conditions that allows comparable results to be obtained, regardless of the laboratory that performs the test. In this sense, the use of recognized and accepted reference methodsis the most effective tool for these guarantees. The activities related to verification and validation of analytical methods has become very important, as there is continuous development, as well as updating techniques and increasingly complex …
Essays in applied microeconomics on water resources management
2017
En el contexto actual de creciente escasez de recursos hídricos, el principal objetivo de esta tesis doctoral es contribuir a la mejora de las políticas urbanas de gestión del agua. En un sentido amplio, las conclusiones centrales derivadas de los ensayos incluidos en la misma se pueden agrupar en torno a cuatro aspectos. En concreto, implicaciones para las políticas de demanda, implicaciones para la gobernanza en la gestión urbana del agua, contribuciones metodológicas, y, finalmente, lecciones de política pública para la gestión del agua en España. Resultados sobre políticas de demanda: Como se ha desarrollado de forma más detallada en la introducción, las políticas de demanda, tanto tari…
Analysis of the process of environmental impact assessment for seawater desalination plants in Spain
2014
Desalination generates drinking water and enhances the economic, social, and environmental development of many areas with few water resources, such as parts of the Middle East, North Africa, and southern Europe (such as Spain and Cyprus). Desalination plants may cause environmental impacts in coastal areas and so it is necessary to submit plans for new plants to a process of environmental impact assessment (EIA) in order to achieve more environmentally viable projects, meaning: optimal locations; appropriately used systems and technologies; effective preventive, compensatory, and corrective measures; and social and environmental acceptance. This article contains a study of the process of en…
A satellite stand-alone procedure for deriving net radiation by using SEVIRI and MODIS products
2018
Abstract In this study, a new stand-alone satellite approach for the estimation of net surface radiation (Rn) has been implemented and validated for the Italian territory. The method uses the MODIS and MSG-SEVIRI time series products and it is independent of the use of ancillary data (i.e. ground measurements). A database of daily measurements of Rn, provided by 9 stations of the FLUXNET network, was used to validate the method in different ecological scenarios in the period 2010-12. The Rn modelled by the proposed approach and the corresponding FLUXNET measurements were in good agreement, with RMSE and R2 of 19.8 Wm−2 and 0.87, respectively, at 8-days scale, and 23.3 Wm−2 and 0.92, respect…
