Morphological, hydrological, biogeochemical and ecological changes and challenges in river restoration - the Thur River case study

River restoration can enhance river dynamics, environmental heterogeneity and biodiversity, but the underlying processes governing the dynamic changes need to be understood to ensure that restoration projects meet their goals, and adverse effects are prevented. In particular, we need to comprehend how hydromorphological variability quantitatively relates to ecosystem functioning and services, biodiversity as well as ground-and surface water quality in restored river corridors. This involves (i) physical processes and structural properties, determining erosion and sedimentation, as well as solute and heat transport behavior in surface water and within the subsurface; (ii) biogeochemical processes and characteristics, including the turnover of nutrients and natural water constituents; and (iii) ecological processes and indicators related to biodiversity and ecological functioning. All these aspects are interlinked, requiring an interdisciplinary investigation approach. Here, we present an overview of the recently completed RECORD (REstored CORridor Dynamics) project in which we combined physical, chemical, and biological observations with modeling at a restored river corridor of the perialpine Thur River in Switzerland. Our results show that river restoration, beyond inducing morphologic changes that reshape the river bed and banks, triggered complex spatial patterns of bank infiltration, and affected habitat type, biotic communities and biogeochemical processes. We adopted an interdisciplinary approach of monitoring the continuing changes due to restoration measures to address the following questions: How stable is the morphological variability established by restoration? Does morphological variability guarantee an improvement in biodiversity? How does morphological variability affect biogeochemical transformations in the river corridor? What are some potential adverse effects of river restoration? How is river restoration influenced by catchment-scale hydraulics [GRAPHICS] and which feedbacks exist on the large scale? Beyond summarizing the major results of individual studies within the project, we show that these overarching questions could only be addressed in an interdisciplinary framework.

4B.05: Plasma Lasma copeptin is associated with insulin resistance in a Swiss population-based study

OBJECTIVE: Previous studies suggest that arginine vasopressin may have a role in metabolic syndrome (MetS) and diabetes by altering liver glycogenolysis, insulin, and glucagon secretion and pituitary ACTH release. We tested whether plasma copeptin, the stable C-terminal fragment of arginine vasopressin prohormone, was associated with insulin resistance and MetS in a Swiss population-based study. DESIGN AND METHOD: We analyzed data from the population-based Swiss Kidney Project on Genes in Hypertension. Copeptin was assessed by an immunoluminometric assay. Insulin resistance was derived from the HOMA model and calculated as follows: (FPI x FPG)/22.5, where FPI is fasting plasma insulin concentration (mU/L) and FPG fasting plasma glucose (mmol/L). Subjects were classified as having the MetS according to the National Cholesterol Education Program Adult Treatment Panel III criteria. Mixed multivariate linear regression models were built to explore the association of insulin resistance with copeptin. In addition, multivariate logistic regression models were built to explore the association between MetS and copeptin. In the two analyses, adjustment was done for age, gender, center, tobacco and alcohol consumption, socioeconomic status, physical activity, intake of fruits and vegetables and 24 h urine flow rate. Copeptin was log-transformed for the analyses. RESULTS: Among the 1,089 subjects included in this analysis, 47% were male. Mean (SD) age and body mass index were 47.4 (17.6) years 25.0 (4.5) kg/m2. The prevalence of MetS was 10.5%. HOMA-IR was higher in men (median 1.3, IQR 0.7-2.1) than in women (median 1.0, IQR 0.5-1.6,P < 0.0001). Plasma copeptin was higher in men (median 5.2, IQR 3.7-7.8 pmol/L) than in women (median 3.0, IQR 2.2-4.3 pmol/L), P < 0.0001. HOMA-IR was positively associated with log-copeptin after full adjustment (β (95% CI) 0.19 (0.09-0.29), P < 0.001). MetS was not associated with copeptin after full adjustment (P = 0.92). CONCLUSIONS: Insulin resistance, but not MetS, was associated with higher copeptin levels. Further studies should examine whether modifying pharmacologically the arginine vasopressin system might improve insulin resistance, thereby providing insight into the causal nature of this association.

Induced pluripotent stem cells as a promising tool to study the effect of interleukin-22 in multiple sclerosis

La sclérose en plaques (SEP) est une maladie démyélinisante du système nerveux central (SNC) provoquant des pertes motrices, sensitives et cognitives. La SEP se déclare chez le jeune adulte ayant des prédispositions génétiques, mais semble induite, par des facteurs environnementaux. La SEP touche principalement les femmes et sa prévalence dans les zones à haut risque, tel que la Suisse, est de 0.1%. Bien que son étiologie exacte reste méconnue, nous savons que la maladie est médiée par des lymphocytes T autoréactifs périphériques, qui infiltrent le SNC où ils activent d'autres cellules immunitaires ainsi que les cellules du SNC elles-mêmes, créant un foyer inflammatoire, qui va attaquer et finir par tuer les oligodendrocytes et les neurones. Les épisodes inflammatoires sont entrecoupés par des phases de rémission associées à une guérison partielle des lésions. Cette première phase de la maladie, comprenant des épisodes inflammatoires et de rémissions est appelé SEP récurrente-rémittente (SEP-RR) et touche 90% des patients. Elle évolue, dans deux-tiers des cas, vers une SEP secondaire progressive (SEP-SP), qui est caractérisée par une progression constante de la maladie, associée à une réduction de l'inflammation mais une augmentation de la neurodégénérescence. Les patients souffrants de SEP primaire progressive (SEP-PP) développent directement les symptômes de la phase progressive de la maladie. Les thérapies disponibles ont considérablement amélioré l'évolution de la maladie des patients SEP-RR, en agissant sur une diminution de la réponse immunitaire et donc de l'inflammation. Cependant, ces traitements sont inefficaces chez les patients SEP-SP et SEP-PP, n'agissant pas sur la neurodégénérescence. IL-22, une cytokine sécrétée notoirement par les cellules Th17, a été associée à la SEP en contribuant à la perméabilisation de la barrière hémato-encéphalique et à l'inflammation du SNC, qui sont des étapes clés de la pathogenèse de la maladie. En outre, le gène codant pour un inhibiteur puissant d'IL- 22, 'IL-22 binding protein' (IL-22BP), a été démontré comme un facteur de risque de la SEP. Ces indices nous ont poussés à nous intéresser de plus près au rôle de l'IL-22 dans la SEP. Nous avons pu montrer qu'IL-22 et IL-22BP étaient augmentées dans le sang des patients SEP par rapport à des sujets sains. Nous avons trouvé qu'IL-22 cible spécifiquement les astrocytes dans le SNC et que son récepteur est particulièrement exprimé dans les lésions des patient SEP. Contre toute attente, nous avons pu montrer que l'IL-22 semble soutenir la survie des astrocytes. Cette découverte, suggérant qu'IL-22 serait protecteur pour le SNC et pour la SEP, confirme de récentes publications et ouvre la voie à de potentielles applications thérapeutiques. En parallèle, dans le but de mieux comprendre l'immunopathogenèse de la SEP, nous avons développé les techniques de culture de cellules souches pluripotentes induites (iPSC). Nos iPSC sont dérivées du sang des donneurs et acquièrent toutes les propriétés des cellules souches embryonnaires après induction. Les iPSC peuvent ensuite être différenciées en différents types de cellules, dont les cellules du SNC. Nous avons ainsi pu obtenir avec succès des neurones, dérivés de cellules du sang, en passant par le stade des iPSC. La prochaine étape consiste à générer des cultures d'astrocytes et d'oligodendrocytes et ainsi obtenir les principales cellules du SNC, le but étant de former de véritables 'cerveaux-en-culture'. Cet outil semble particulièrement adapté à l'étude de l'activité de diverses molécules sur les cellules du SNC, comme par exemple l'IL-22 et d'autres molécules ayant un potentiel intérêt thérapeutique au niveau du SNC. Le but ultime étant de développer des co-cultures de cellules du SNC avec des cellules immunitaires autologues, de patients SEP et de sujets sains, afin de mettre en évidence l'attaque des cellules du SNC par des leucocytes autoréactifs. Ce projet prospectif a permis d'accroître nos connaissance sur des aspects immunitaires de la SEP et à pour but de mieux comprendre l'immunopathogenèse de la SEP afin d'élaborer de nouvelles stratégies thérapeutiques. -- La sclérose en plaques est une maladie auto-inflammatoire du système nerveux central conduisant à la destruction de la myéline, indispensable à la conduction nerveuse, et finalement à la mort des neurones eux-mêmes. Cela a pour conséquence des pertes motrices, sensorielles et cognitives, qui ont tendance à s'aggraver au fil de la maladie. Elle se déclare chez le jeune adulte, entre l'âge de 20 et 40 ans, et prédomine chez la femme. En Suisse, environ une personne sur l'OOO est atteinte de sclérose en plaques. Les causes exactes de cette maladie, qui incluent des facteurs génétiques et environnementaux, sont encore mal connues. Des traitements de plus en plus efficaces ont été développés ces dernières années et ont permis de drastiquement améliorer l'évolution de la maladie chez les patients atteints de sclérose en plaques. Cependant, ces traitements ne sont efficaces que sur certaines catégories de patients et peuvent engendrer de lourds effets secondaires. Ces thérapies agissent presque exclusivement sur les cellules du système immunitaire en les désactivant partiellement, mais pas sur les cellules nerveuses, qui sont pourtant celles qui conditionnent le devenir du patient. Le développement de médicaments protégeant ou permettant la régénération des cellules du système nerveux central est donc primordial. L'étude de l'interleukine-22 nous a permis de montrer que cette cytokine ('hormone' du système immunitaire) pouvait cibler spécifiquement les astrocytes, des cellules gliales qui jouent un rôle central dans le maintien de l'équilibre du système nerveux central. Nos recherches ont montré que cette interleukine-22 permettrait une meilleure survie des astrocytes durant la phase aiguë de la maladie et aurait aussi des propriétés neuroprotectrices. En parallèle, nous sommes en train de développer un nouveau modèle in vitro d'étude de la sclérose en plaques grâce à la technologie des cellules souches pluripotentes induites. Ces cellules souches sont induites à partir de cellules du sang du donneur et acquièrent toutes les caractéristiques des cellules souches embryonnaires présentes dans un organisme en formation. Ainsi, ces cellules souches pluripotentes ont, par exemple, la capacité de se différencier en cellules du système nerveux central. Nous avons pu, de cette manière, obtenir des neurones. Le but ultime serait de pouvoir reconstituer une ébauche de cerveau in vitro, en cultivant ensemble différents types de cellules du système nerveux central, afin d'y réaliser des expériences avec des cellules immunitaires du même donneur. Ces travaux ont pour but d'améliorer notre compréhension de la pathogenèse de la sclérose en plaques et de permettre le développement de nouvelles stratégies thérapeutiques. --Multiple sclerosis (MS) is a demyelinating disease of the central nervous system leading to cognitive, sensitive and motor disabilities. MS occurs in genetically predisposed young adults with probable environmental triggers. MS affects predominantly women and its prevalence in high risk area such as Switzerland is 0.1%. Though its exact aetiology remains undetermined, we know that autoreactive T cells from de periphery are reactivated and recruited into the central nervous system (CNS) were they further activate other immune cells and resident cells, creating inflammatory foci, where oligodendrocytes and neurons are insulted and, eventually, killed. Inflammatory episodes, called relapses, are interspersed with remission phases where partial recovery of the lesions occurs. This first phase of the disease, occurring in 90% of the patients, is called relapsing-remitting MS (RR-MS) and is leading, in two-third of the cases, to secondary-progressive MS (SP-MS), where there is a continuous steady progression of the disease, associated with reduced inflammation but increased neurodegeneration. Primary-progressive MS (PP-MS) patients experience directly this progressive phase of the disease. Whereas disease modifying therapies have dramatically ameliorated the disease course of RR-MS patients by dampening immunity and, in turn, inflammation, treatments of SP-MS and PP-MS patients, who suffer primarily from the neurodegenerative aspect of the disease, are still inexistent. IL-22, a pro-inflammatory Th17 cell cytokine, has been associated with MS by participating to blood-brain barrier infiltration and CNS inflammation, which are crucial steps in MS pathogenesis. In addition, the gene coding for IL-22 binding protein (IL-22BP), which is a potent secreted IL-22 inhibitor, has been associated with MS risk. These findings call for further investigation on the role of IL-22 in MS. We detected increased IL-22 and IL-22BP in the blood of MS patients as compared to healthy controls. Acting exclusively on cells of nonhematopoietic origin, we found that IL-22 targets specifically astrocytes in the CNS and that its receptor is highly expressed in the lesion of MS patients. Unexpectedly, we found that IL-22 seems to promote survival of astrocytes. This finding, suggesting that IL-22 might be protective for the CNS in the context of MS, is consistent with recent publications and might open putative therapeutic applications at the CNS level. In parallel, with the aim of better understanding the immunopathogenesis of MS, we developed induced pluripotent stem cell (iPSC) techniques. IPSC are derived from blood cells of the donors and bear embryonic stem cell properties. IPSC can be differentiated into various cell types including CNS cells. We successfully obtained neurons derived from the donor blood cells, through iPSC. We further aim at developing astrocytes and oligodendrocytes cultures to recreate a 'brain-in-a-dish'. This would be a powerful tool to test the activity of various compounds on CNS cells, including IL-22 and other putative neuroprotective drugs. Ultimately, the goal is to develop co-cultures of CNS cells with autologous immune cells of MS patients as well as healthy controls to try to expose evidence of CNS cells targeted by autoreactive leukocytes. This prospective project has increased our knowledge of immune aspects of MS and further aims at better understanding the immunopathology of MS in order to pave the way to the elaboration of new therapeutic strategies.

Clopidogrel Pharmacogenetics, resistance to antiplatelet therapy in ischemic stroke by Epigenome Wide Association Study (EWAS).

Clopidogrel is a widely used antiplatelet drug used in preventing vascular events after suffering a first stoke. Genome-wide association studies (GWAS) has not been able to establish a clear association between polymorphisms and recurrence. Therefore in the present final master project an epigenetic approach is proposed. Using an array based technology, 450.000 CpG sites across all genome were assessed in 48 individuals (21 cases and 21 controls). Looking at differentially methylated levels between cases and controls, 58 CpG sites (DMGs) were found. Although, no clear locus was observed. Looking individually to each 49 genes, two appeared to be important to our study. TRAF3 and ADAMTS2 are gens highly related to platelet aggregation. In orther to confirm these result, a new DNA methylation study will be done in a larger cohort, using Sequenom technology.

Use of the EpiNet database for observational study of status epilepticus in Auckland, New Zealand.

The EpiNet project has been established to facilitate investigator-initiated clinical research in epilepsy, to undertake epidemiological studies, and to simultaneously improve the care of patients who have records created within the EpiNet database. The EpiNet database has recently been adapted to collect detailed information regarding status epilepticus. An incidence study is now underway in Auckland, New Zealand in which the incidence of status epilepticus in the greater Auckland area (population: 1.5 million) will be calculated. The form that has been developed for this study can be used in the future to collect information for randomized controlled trials in status epilepticus. This article is part of a Special Issue entitled "Status Epilepticus".

Does working memory training affect decision making ? : a neuroeconomic study

We all make decisions of varying levels of importance every day. Because making a decision implies that there are alternative choices to be considered, almost all decision involves some conflicts or dissatisfaction. Traditional economic models esteem that a person must weight the positive and negative outcomes of each option, and based on all these inferences, determines which option is the best for that particular situation. However, individuals rather act as irrational agents and tend to deviate from these rational choices. They somewhat evaluate the outcomes' subjective value, namely, when they face a risky choice leading to losses, people are inclined to have some preference for risk over certainty, while when facing a risky choice leading to gains, people often avoid to take risks and choose the most certain option. Yet, it is assumed that decision making is balanced between deliberative and emotional components. Distinct neural regions underpin these factors: the deliberative pathway that corresponds to executive functions, implies the activation of the prefrontal cortex, while the emotional pathway tends to activate the limbic system. These circuits appear to be altered in individuals with ADHD, and result, amongst others, in impaired decision making capacities. Their impulsive and inattentive behaviors are likely to be the cause of their irrational attitude towards risk taking. Still, a possible solution is to administrate these individuals a drug treatment, with the knowledge that it might have several side effects. However, an alternative treatment that relies on cognitive rehabilitation might be appropriate. This project was therefore aimed at investigate whether an intensive working memory training could have a spillover effect on decision making in adults with ADHD and in age-matched healthy controls. We designed a decision making task where the participants had to select an amount to gamble with the chance of 1/3 to win four times the chosen amount, while in the other cases they could loose their investment. Their performances were recorded using electroencephalography prior and after a one-month Dual N-Back training and the possible near and far transfer effects were investigated. Overall, we found that the performance during the gambling task was modulated by personality factors and by the importance of the symptoms at the pretest session. At posttest, we found that all individuals demonstrated an improvement on the Dual N-Back and on similar untrained dimensions. In addition, we discovered that not only the adults with ADHD showed a stable decrease of the symptomatology, as evaluated by the CAARS inventory, but this reduction was also detected in the control samples. In addition, Event-Related Potential (ERP) data are in favor of an change within prefrontal and parietal cortices. These results suggest that cognitive remediation can be effective in adults with ADHD, and in healthy controls. An important complement of this work would be the examination of the data in regard to the attentional networks, which could empower the fact that complex programs covering the remediation of several executive functions' dimensions is not required, a unique working memory training can be sufficient. -- Nous prenons tous chaque jour des décisions ayant des niveaux d'importance variables. Toutes les décisions ont une composante conflictuelle et d'insatisfaction, car prendre une décision implique qu'il y ait des choix alternatifs à considérer. Les modèles économiques traditionnels estiment qu'une personne doit peser les conséquences positives et négatives de chaque option et en se basant sur ces inférences, détermine quelle option est la meilleure dans une situation particulière. Cependant, les individus peuvent dévier de ces choix rationnels. Ils évaluent plutôt les valeur subjective des résultats, c'est-à-dire que lorsqu'ils sont face à un choix risqué pouvant les mener à des pertes, les gens ont tendance à avoir des préférences pour le risque à la place de la certitude, tandis que lorsqu'ils sont face à un choix risqué pouvant les conduire à un gain, ils évitent de prendre des risques et choisissent l'option la plus su^re. De nos jours, il est considéré que la prise de décision est balancée entre des composantes délibératives et émotionnelles. Ces facteurs sont sous-tendus par des régions neurales distinctes: le chemin délibératif, correspondant aux fonctions exécutives, implique l'activation du cortex préfrontal, tandis que le chemin émotionnel active le système limbique. Ces circuits semblent être dysfonctionnels chez les individus ayant un TDAH, et résulte, entre autres, en des capacités de prise de décision altérées. Leurs comportements impulsifs et inattentifs sont probablement la cause de ces attitudes irrationnelles face au risque. Cependant, une solution possible est de leur administrer un traitement médicamenteux, en prenant en compte les potentiels effets secondaires. Un traitement alternatif se reposant sur une réhabilitation cognitive pourrait être appropriée. Le but de ce projet est donc de déterminer si un entrainement intensif de la mémoire de travail peut avoir un effet sur la prise de décision chez des adultes ayant un TDAH et chez des contrôles sains du même âge. Nous avons conçu une tâche de prise de décision dans laquelle les participants devaient sélectionner un montant à jouer en ayant une chance sur trois de gagner quatre fois le montant choisi, alors que dans l'autre cas, ils pouvaient perdre leur investissement. Leurs performances ont été enregistrées en utilisant l'électroencéphalographie avant et après un entrainement d'un mois au Dual N-Back, et nous avons étudié les possibles effets de transfert. Dans l'ensemble, nous avons trouvé au pré-test que les performances au cours du jeu d'argent étaient modulées par les facteurs de personnalité, et par le degré des sympt^omes. Au post-test, nous avons non seulement trouvé que les adultes ayant un TDAH montraient une diminutions stable des symptômes, qui étaient évalués par le questionnaire du CAARS, mais que cette réduction était également perçue dans l'échantillon des contrôles. Les rsultats expérimentaux mesurés à l'aide de l'éléctroencéphalographie suggèrent un changement dans les cortex préfrontaux et pariétaux. Ces résultats suggèrent que la remédiation cognitive est efficace chez les adultes ayant un TDAH, mais produit aussi un effet chez les contrôles sains. Un complément important de ce travail pourrait examiner les données sur l'attention, qui pourraient renforcer l'idée qu'il n'est pas nécessaire d'utiliser des programmes complexes englobant la remédiation de plusieurs dimensions des fonctions exécutives, un simple entraiment de la mémoire de travail devrait suffire.

Knowledge creation and transfer in an iterative project environment

This Master’s Thesis examines knowledge creation and transfer processes in an iterative project environment. The aim is to understand how knowledge is created and transferred during an actual iterative implementation project which takes place in International Business Machines (IBM). The second aim is to create and develop new working methods that support more effective knowledge creation and transfer for future iterative implementation projects. The research methodology in this thesis is qualitative. Using focus group interviews as a research method provides qualitative information and introduces the experiences of the individuals participating in the project. This study found that the following factors affect knowledge creation and transfer in an iterative, multinational, and multi-organizational implementation project: shared vision and common goal, trust, open communication, social capital, and network density. All of these received both theoretical and empirical support. As for future projects, strengthening these factors was found to be the key for more effective knowledge creation and transfer.

Mercury analysis in hair: comparability and quality assessment within the transnational COPHES/DEMOCOPHES project

Human biomonitoring (HBM) is an effective tool for assessing actual exposure to chemicals that takes into account all routes of intake. Although hair analysis is considered to be an optimal biomarker for assessing mercury exposure, the lack of harmonization as regards sampling and analytical procedures has often limited the comparison of data at national and international level. The European-funded projects COPHES and DEMOCOPHES developed and tested a harmonized European approach to Human Biomonitoring in response to the European Environment and Health Action Plan. Herein we describe the quality assurance program (QAP) for assessing mercury levels in hair samples from more than 1800 mother-child pairs recruited in 17 European countries. To ensure the comparability of the results, standard operating procedures (SOPs) for sampling and for mercury analysis were drafted and distributed to participating laboratories. Training sessions were organized for field workers and four external quality-assessment exercises (ICI/EQUAS), followed by the corresponding web conferences, were organized between March 2011 and February 2012. ICI/EQUAS used native hair samples at two mercury concentration ranges (0.20-0.71 and 0.80-1.63) per exercise. The results revealed relative standard deviations of 7.87-13.55% and 4.04-11.31% for the low and high mercury concentration ranges, respectively. A total of 16 out of 18 participating laboratories the QAP requirements and were allowed to analyze samples from the DEMOCOPHES pilot study. Web conferences after each ICI/EQUAS revealed this to be a new and effective tool for improving analytical performance and increasing capacity building. The procedure developed and tested in COPHES/DEMOCOPHES would be optimal for application on a global scale as regards implementation of the Minamata Convention on Mercury.

How women and men project their gender prototypes on leader prototypes.

Both role incongruency theory (Eagly & Karau, 2002) and the lack of fit model by Heilman (1983) suggest that the underrepresentation of women in leadership positions can be explained by the male-typedness of leader prototypes. We examine how women and men project their gender prototypes onto leader prototypes. We found initially that men more so than women projected their gender prototypes on leader prototypes. For men there is more of an overlap between a prototypical men and a prototypical leader than there is an overlap between a prototypical woman and a prototypical leader. Women, however, do not engage in so called relative ingroup projection. In the current study, we further decompose this finding asking whether the gender difference in relative ingroup projection on leadership prototypes is driven by female prototypes, male prototypes, and/or leader prototypes. We further examine to what extent this gender difference is more manifested on positively valenced or negatively valenced attributes of prototypes. Our findings show that, while women and men have similar prototypes of leaders and men on both positively and negatively valenced attributes, men relative to women have less favorable prototypes of women but only on positively valenced attributes. An interesting implication is that efforts to address gender differences in the projection of gender prototypes onto leader prototypes should focus less on leader prototypes and more on the female prototypes. Theoretically, our findings allude to the importance of distinguishing between more subtle (evaluating the outgroup less positively on positive properties) and less subtle forms (evaluating the outgroup more negatively on negative properties) of outgroup derogation.

Developing Launching Processes — A Case Study

New product launches are becoming more and more important to companies around the globe. Being first on the market is a good place to be, and it will mostly likely bring the best profits. Gaining that desired position requires a lot of work where cooperation inside as well as outside of the company need to be in line. This thesis discusses launching processes in a pharmaceutical firm. The topic is looked at from supply chain management's point of view where purchasing department's role is emphasized. Additionally, launching strategies related to launches are investigated and the idea of internal alignment is introduced. Moreover, the topic is examined in project and process management perspective; how with the tools of project and process management the launching processes could be improved. The main findings reveal that there are many improvement points in the current launching process. Problems in the areas of information exchange, leadership and internal alignment were discovered yet trust and confidence for the better future compound the interviewees. This study presents what are the most important factors for a successful product launch and how the current processes could be streamlined.

Landscape Systems and Human Land-Use Interactions in Mediterranean Highlands and Littoral Plains during the Late Holocene: Integrated Analysis from the InterAmbAr Project (North-Eastern Catalonia).

The main goal of the InterAmbAr reseach project is to analyze the relationships between landscape systems and human land-use strategies on mountains and littoral plains from a long-term perspective. The study adopts a high resolution analysis of small-scale study areas located in the Mediterranean region of north-eastern Catalonia. The study areas are distributed along an altitudinal transect from the high mountain (above 2000m a.s.l.) to the littoral plain of Empordà (Fig. 1). High resolution interdisciplinary research has been carried out from 2010, based on the integration of palaeoenvironmental and archaeological data. The micro-scale approach is used to understand human-environmental relationships. It allows better understanding of the local-regional nature of environmental changes and the synergies between catchment-based systems, hydro-sedimentary regimes, human mobility, land-uses, human environments, demography, etc.

An interactive web-GIS tool for risk analysis: a case study in the Fella River basin, Italy

This paper presents a prototype of an interactive web-GIS tool for risk analysis of natural hazards, in particular for floods and landslides, based on open-source geospatial software and technologies. The aim of the presented tool is to assist the experts (risk managers) in analysing the impacts and consequences of a certain hazard event in a considered region, providing an essential input to the decision-making process in the selection of risk management strategies by responsible authorities and decision makers. This tool is based on the Boundless (OpenGeo Suite) framework and its client-side environment for prototype development, and it is one of the main modules of a web-based collaborative decision support platform in risk management. Within this platform, the users can import necessary maps and information to analyse areas at risk. Based on provided information and parameters, loss scenarios (amount of damages and number of fatalities) of a hazard event are generated on the fly and visualized interactively within the web-GIS interface of the platform. The annualized risk is calculated based on the combination of resultant loss scenarios with different return periods of the hazard event. The application of this developed prototype is demonstrated using a regional data set from one of the case study sites, Fella River of northeastern Italy, of the Marie Curie ITN CHANGES project.

Treatment of micropollutants in municipal wastewater: study of a sequential batch biofilter

All the experimental part of this final project was done at Laboratoire de Biotechnologie Environnementale (LBE) from the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, during 6 months (November 2013- May 2014). A fungal biofilter composed of woodchips was designed in order to remove micropollutants from the effluents of waste water treatment plants. Two fungi were tested: Pleurotus ostreatus and Trametes versicolor in order to evaluate their efficiency for the removal of two micropollutants: the anti-inflammatory drug naproxen and the antibiotic sulfamethoxazole,. Although Trametes versicolor was able to degrade quickly naproxen, this fungus was not any more active after one week of operation in the filter. Pleurotus ostreatus was, on contrary, able to survive more than 3 months in the filter, showing good removal efficiencies of naproxen and sulfamethoxazole during all this period, in tap water but also in real treated municipal wastewater. Several other experiments have provided insight on the removal mechanisms of these micropollutants in the fungal biofilter (degradation and adsorption) and also allowed to model the removal trend. Fungal treatment with Pleurotus ostreatus grown on wood substrates appeared to be a promising solution to improve micropollutants removal in wastewater.
