The results of the vine varieties reconversion measures in the North-Eastern Romania / Résultats de la mesure de reconversion des cépages dans le Nor…
2016
The vine varieties reconversion measure is one of the many benefits that the Romania's integration to the European Union brings to the wine sector. This study aims to analyze the results of this measure during 2007–2015 in the Romania's North-East Region. From the Vineyard Plantation Register, the plots noble vine parcels of each department were divided into two groups: those who existed in the field in before and those converted during the period. The surface of each group was classified first, based on the color of the grapes and secondarily, based on the pair international varieties – non international varieties. The conversion affected 3 of 6 departments. In Iasi, where the proportion o…
School aspirations, cognitive skills and wage expectations of French Undergraduates
2013
en ligne : http://cemapre.iseg.utl.pt/educonf/2e3/files/submissions_to_web/Bonnard%20Claire_%20Giret%20Jean-Francois_Lambert-Le%20Mener%20Marielle.pdf; This paper aims to study the earnings expectations of first-year students at a French university and to compare them with the observed earnings of young people in the labour market for that same year. Our findings highlight the importance of the environment in which students make their choices about education. Expected earnings are proportionally higher when their parents seem to be involved in the careers guidance, even controlling for the effect of parental socio-economic status. The positive opinion of parents about the orientation or the…
Impact of membrane addition for effluent extraction on the performance and sludge characteristics of upflow anaerobic sludge blanket reactors treatin…
2015
Abstract In this study, the impact of membrane incorporation for effluent extraction on the performance of an upflow anaerobic sludge blanket (UASB) reactor treating municipal wastewater was investigated in terms of system performance and sludge characteristics. A laboratory-scale system was operated in two different operational stages: (i) as a sole UASB reactor and (ii) as an anaerobic membrane bioreactor (AnMBR). Membrane incorporation induced an accumulation of fine particles and a decrease in extracellular polymeric substances (EPS), resulting in a decrease in particle size distribution (PSD) and, thus, a drop in sludge settleability. Deterioration of sludge settleability led to an inc…
The state of water resources in major mediterranean islands
2014
This work analyses the state of water resources in six Mediterranean islands: Corsica, Crete, Cyprus, Mallorca, Malta and Sicily. The analysis is focused on the prevailing social, economic and hydroclimatological characteristics of these islands in order to identify the main common features affecting water availability, demand and use. A detailed analysis of the state of water resources in all the considered islands has been carried out. A background of current conditions relating to freshwater availability, quality and use has been established. Different strategies to face water scarcity and enhance water quality in theislands have been assessed in a context of climate change which is a co…
The Economic Impact of the South-North Water Transfer Project in China: A Computable General Equilibrium Analysis
2006
Water resources are unevenly spread in China. Especially the basins of the Yellow, Hui and Hai rivers in the North are rather dry. To increase the supply of water in these basins, the South-to-North Water Transfer project (SNWT) was launched. Using a computable general equilibrium model this study estimates the impact of the project on the economy of China and the rest of the world. We contrast three alternative groups of scenarios. All are directly concerned with the South-to-North water transfer project to increase water supply. In the first group of scenarios additional supply implies productivity gains. We call it the "non-market" solution. The second group of scenarios is called "marke…
Trends in Research and Publication: Science 2.0 and Open Access
2009
This paper considers current trends in academic research and publication, in particular as seen from the control community. The introduction of Web 2.0 applications for scientists and engineers is currently changing the way research is being conducted. In the near future, participants in the research community will be able to share ideas, data and results like never before. They will also be able to manage the rapidly increasing amount of scientific information much more effectively than today through collaborative efforts enabled by the new Internet tools. However, an important premise for such a development is the availability of research material. Many research results are currently shie…
Analysis of the filtration efficiency of white wines using different filter aids
2010
The global wine market, having recently entered into full crisis, is suffering some changes in its production and marketing. The reasons for these changes are mainly due to new trends in consumer demand for wine safety and quality standards at low cost. Social cellars, in order to be included in this new trend, should focus on the rationalization of the production techniques to reduce the costs and improve the quality of wine. In the case of winemaking for the production of a wine stored in a bag-in-box, filtration is a very important technique because it gives the finished product clearness and stability. The experimentation was based on the application of a low cost filtration technique o…
Techno-Economic Case Study of Micro-Grid System at Soccer Club of Skagerak Arena Norway
2020
The photovoltaic system and battery energy storage can be used in a microgrid system for reducing peak demand from the grid and it enhances overall techno-economic performance of the system. In this work, a functioning micro-grid of 800 kWp photovoltaic system and 1 MWh lithium ion battery, located at Soccer Club of Skagrek Arena (Norway), is used for techno-economic analysis and operational load from years 2015 to 2018. The system performance has been analyzed for understanding the techno-economic operation, and contributions from the PV and battery energy storage for reducing peak demand from the grid. In this study, it has been observed that the integration of PV and battery energy stora…
The Importance of Recovery from Work in Intensified Working Life
2021
This chapter focuses on intensified working life via the intensified job demands (IJDs) model from the perspective of recovery from work by paying particular attention to the potentially mediating and buffering roles of recovery in the linkages between IJDs and their consequences. In empirical analyses, we examined the buffering role of psychological detachment from work during off-job time in the relationship between intensified job demands and job performance and meaning of work. We found that high psychological detachment, as a recovery experience, buffered against work intensification over time in relation to job performance and meaning of work. Thus, good detachment from work during of…
Modelling hydrolysis: Simultaneous versus sequential biodegradation of the hydrolysable fractions
2018
Hydrolysis is considered the limiting step during solid waste anaerobic digestion (including co-digestion of sludge and biosolids). Mechanisms of hydrolysis are mechanistically not well understood with detrimental impact on model predictive capability. The common approach to multiple substrates is to consider simultaneous degradation of the substrates. This may not have the capacity to separate the different kinetics. Sequential degradation of substrates is theoretically supported by microbial capacity and the composite nature of substrates (bioaccessibility concept). However, this has not been experimentally assessed. Sequential chemical fractionation has been successfully used to define i…
