Projecting biodiversity and wood production in future forest landscapes: 15 key modeling considerations
2017
A variety of modeling approaches can be used to project the future development of forest systems, and help to assess the implications of different management alternatives for biodiversity and ecosystem services. This diversity of approaches does however present both an opportunity and an obstacle for those trying to decide which modeling technique to apply, and interpreting the management implications of model output. Furthermore, the breadth of issues relevant to addressing key questions related to forest ecology, conservation biology, silviculture, economics, requires insights stemming from a number of distinct scientific disciplines. As forest planners, conservation ecologists, ecologica…
Estudio de la variabilidad genética de repoblaciones de Quercus ilex L. subsp. ballota (Desf.) Samp. in Bol. en Andalucìa
2005
An adequate management of the reproductive material for reforestation activities is fundamental in the conservation of forest genetic resources. In the present work the levels of genetic diversity and differentiation between artificial stands of Quercus ilex and the adjacent natural stands are assessed with nuclear microsatellites. Also, it was possible to analyse the natural population used as seed source for one of the reforestations studied. The levels of genetic differentiation between natural and artificial stands and the decrease of genetic diversity from the seed origin population to the reforestation are discussed in relation to the transference of seed among provenance regions and …
RED. Revista de educación a distancia
2021
El mundo requiere personas con conocimientos, habilidades y actitudes que permitan un desarrollo completo de la ciudadanía en un ecosistema digital. Una respuesta educativa a esta exigencia social es la competencia digital. Así, esta finalidad exige niveles óptimos de desarrollo de la Competencia Digital Docente (CDD), en especial en el sector de la Formación Profesional (FP). Con la idea de atender este contexto educativo, en este trabajo se propone un marco de comprensión que integra de forma unitaria la visión sobre la pedagogía, los recursos y la evaluación para entender, evaluar y proponer mejoras en la competencia digital del profesorado de FP. Empleando un enfoque cualitativo, se rea…
Fuzzy logic controller and game theory based distributed energy resources allocation
2020
Energy management and demand control through conventional energy generation sources are challenging for energy providers. Distributed energy resources (DERs) allocation near load centers may provide a suitable solution. The main contribution of the paper improves the voltage profile and reduce the active and reactive power losses in the distribution network. DERs are integrated with IEEE 33 bus system using fuzzy logic controller (FLC) and game theory for two different cases with unity and 0.9 power factor (PF) and compares with conventional methods of integration (i.e., modified novel method, power loss sensitivity method, voltage sensitivity analysis method). The capacity of DERs is optim…
Paroles de chef : modèles communicationnels d’une organisation professionnelle
2016
Dans un restaurant, communiquer correspond à informer la clientèle, dialoguer avec elle, collaborer avec les équipes, et diffuser une image du restaurant, des mets et du chef. La communication apparente du chef de cuisine précise le lien qui existe entre lui et son personnel, lui et les clients, lui et les fournisseurs, et plus rarement entre lui et les médias ou supports de communication. Apportant la communication organisationnelle, formelle et normative, auprès de ses subalternes comme de ses fournisseurs, le chef cuisinier tente de diffuser une communication mi-naturelle afin de parfaire une certaine convivialité, et mi-formelle afin de transmettre ou confirmer son savoir-faire. Il s’ag…

Management of irrigation water and nutrient demands of tomato (Lycopersicon esculentum Mill.) using urban treated wastewater from a pilot-scale horiz…
2017
The reuse of treated wastewater (TWW) in crop irrigation is an advanced and rational approach to water resource management in agriculture. Results would seem to demonstrate that it could be an extremely important tool in the reduction of freshwater (FW) consumption in agriculture, at the same time helping to increase crop yields through the transfer of nutrients required for crop growth. In arid and semi-arid areas of the Mediterranean, constructed wetlands can play a key role in the treatment and reuse of wastewater due to their multifunctional nature. The aim of this study was to manage water and nutrient requirements of tomato (Lycopersicon esculentum Mill.) using TWW from a pilot-scale …
A management and optimisation model for water supply planning in water deficit areas
2014
Summary The integrated water resources management approach has proven to be a suitable option for efficient, equitable and sustainable water management. In water-poor regions experiencing acute and/or chronic shortages, optimisation techniques are a useful tool for supporting the decision process of water allocation. In order to maximise the value of water use, an optimisation model was developed which involves multiple supply sources (conventional and non-conventional) and multiple users. Penalties, representing monetary losses in the event of an unfulfilled water demand, have been incorporated into the objective function. This model represents a novel approach which considers water distri…
A hybrid statistical decision-making optimization approach for groundwater vulnerability considering uncertainty.
2021
Recognizing the vulnerable areas for contamination is a feasible way to protect groundwater resources. The main contribution of the paper is developing a hybrid statistical decision-making model for evaluating the vulnerability of Shiraz aquifer, southern Iran, with modified DRASTIC (depth to the water table, net recharge, aquifer media, soil media, topography, impact of the vadose zone, and hydraulic conductivity) by using the genetic algorithm (GA), the analytical hierarchy process (AHP) method, and factorial analysis (FA). First, considering the variation of the uncertain parameters, 32 scenarios were defined to perform factorial analysis. Then using the AHP method and GA, DRASTIC parame…
