An Approach to Delineate Groundwater Bodies at Risk: Seawater Intrusion in Liepāja (Latvia)

2018

Groundwater quality in coastal areas is frequently affected by seawater intrusion as a consequence of intensive water consumption. To achieve “good chemical status” of a groundwater body according to Water Framework Directive the effects of saline or other intrusions should not be observed. Groundwater pumping in former decades has caused a significant seawater intrusion into confined aquifer in Liepāja and has led to deterioration of relatively wide coastal area of the third largest city in Latvia. However, the area affected by seawater intrusion is a small part of groundwater body F1 which overall chemical status is good. Thus, no specific management measures have been applied to explore …

ROMANIAN SMES VERSUS THE GLOBAL FINANCIAL CRISISIMPEDIMENTS AND OPPORTUNITIES

2012

This paper studies the way small and medium sized enterprises have reacted towards the global financial crisis. It also attempts to study the impact this crisis had on both the activity of these enterprises and on the business mentality in Romania. The article studies the reasons which determined the SMEs’ vulnerability during the crisis; these belong to a wide range, spreading from the tightening of the financing options or of the activity, up to the management’s nature. The impact of the economic crisis is studied starting with the statistics in the specialty literature, which highlight the SMEs’ situation starting with 2008. Having as support these numbers, the paper analyzes the effects…

The Use of Non-Conventional Water Resources as a Means of Adaptation to Drought and Climate Change in Semi-Arid Regions: South-Eastern Spain

2019

Drought is a climatic risk with notable repercussions on water supply systems. The aim of this study is to analyze the principal measures for management and planning implemented during recent decades in south-eastern Spain (Segura River Basin) to respond to drought situations, focusing on the role played by non-conventional water resources (desalination and treated water). The results demonstrate that the study area (despite being one of the driest places of Spain) is less vulnerable to drought than regions with an Atlantic climate and greater availability of water. This has been possible thanks to the integration of non-conventional water resources as a means of adaptation to confront this…

Impact of Farmland Abandonment on Water Resources and Soil Conservation in Citrus Plantations in Eastern Spain

2019

Due to the reduction in the prices of oranges on the market and social changes such as the ageing of the population, traditional orange plantation abandonment in the Mediterranean is taking place. Previous research on land abandonment impact on soil and water resources has focused on rainfed agriculture abandonment, but there is no research on irrigated land abandonment. In the Valencia Region&mdash

Turbulence in River and Maritime Hydraulics

2018

Understanding of the role of turbulence in controlling transport processes is of paramount importance for the preservation and protection of aquatic ecosystems, the minimisation of deleterious consequences of anthropogenic activity, and the successful sustainable development of river and maritime areas. In this context, the present Special Issue collects 15 papers which provide a representation of the present understanding of turbulent processes and their effects in river and maritime environments. The presented collection of papers is not exhaustive but it allows for highlighting key priority areas and knowledge gaps in this field of research.

Enhancing a Transition to a Circular Economy in the Water Sector: The EU Project WIDER UPTAKE

2021

A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concen…

A Conceptual Framework for Using and Evaluating Web-Based Learning Resources in School Education

2010

Published version of an article from the journal:Journal of Information Technology Education. Also available from the publisher: http://www.jite.org/documents/Vol9/JITEv9p053-079Hadjerrouit743.pdf Web-based learning resources (WBLRs) have provided teachers with a wide range of new teachingexperiences that are not possible in traditional classroom. However, little research has beendone as to which approach to WBLRs is suitable to address issues that are pertinent to learning.This paper proposes a conceptual framework to explore the design and evaluation of WBLRs inschool education. The paper also examines the way in which the framework is used to evaluatestudents? and teachers? perceptions o…

Mobbing – et forsøk på nye teoretiske perspektiv

2014

Published version of an article in the journal: Studier i Pædagogisk Filosofi. Also available from the publisher at: http://ojs.statsbiblioteket.dk/index.php/spf/article/view/13325 Open Access This article discusses the understanding of bullying and how it first appears as a phenomenon in early childhood. Empirical research on the social life of young children indicates a capacity for empathy that is independent of social learning. Based upon Merleau-Ponty`s philosophy of the body and Levinas’s existentialist notion of the origin of morality, the article emphasize empathy and the sense of responsibility as a fundamental event in our initial encounter with one another – not learned competence…
