Ocean acidification and elevated temperature negatively affect recruitment, oxygen consumption and calcification of the reef-building Dendropoma cris…
2019
Expected temperature rise and seawater pH decrease may affect marine organism fitness. By a transplant experiment involving air-temperature manipulation along a natural CO2 gradient, we investigated the effects of high pCO(2) (similar to 1100 mu atm) and elevated temperature (up to +2 degrees C than ambient conditions) on the reproductive success, recruitment, growth, shell chemical composition and oxygen consumption of the early life stages of the intertidal reef-building vermetid Dendropoma cristatum. Reproductive success was predominantly affected by temperature increase, with encapsulated embryos exhibiting higher survival in control than elevated temperature conditions, which were in t…
Arsenic Pollution in the Southwest of Tuscany: Monitoring of Cornia Catchment Basin
2006
The territory of Colline Metallifere, in SW Tuscany, is characterized by the presence of strong arsenic anomalies. Some hypotheses, formulated in the last 20 years, based on geological and mineralogical factors have failed to explain the peculiar distribution of this toxic element in soil, fluvial sediments and ground water. Our research group has been studying for four years the problem of arsenic pollution in this district to investigate the origin and the mechanism of As diffusion in the environment. In particular we started a comparative study based on the extensive sampling of the stream sediments of the main waterways of Colline Metallifere (Pecora, Bruna and Cornia and their tributar…
Comparing long term sediment records to current biological quality element data – Implications for bioassessment and management of a eutrophic lake
2012
Defining reference conditions for lakes situated in areas of human settlement and agriculture is rarely straightforward, and is especially difficult within easily eroding and nutrient rich watersheds. We used diatoms, cyanobaterial akinetes, remains of green algae and chironomid head capsules from sediment samples of Lake Kirmanjarvi, Finland, to assess its deviation from the initial ecological status. These site-specific records of change were compared to current type-specific ecological status assessment. All paleolimnological data indicated deviation from natural conditions and mirrored the current, monitoring-based assessment of “moderate” ecological lake status. However, the sediment d…

The logic of the construction of rural politics: political discourses on rurality in norway
2009
Two competing discourses emerge from a careful reading of parliamentary debates in Norway on rural development. One regards rural values as intrinsic, while the other regards the rural as an actor ...
The European Union's Proposal for an International Investment Court: Significance, Innovations and Challenges Ahead
2016
International audience; Rampant discontent with the current system that governs the protection of international investment and the functioning of investment tribunals has led to a widespread view that there is an urgent need for reform. This is particularly pronounced in the context of investor-state dispute settlement (ISDS). The European Union (EU) has responded to this need by proposing the creation of an international investment court. With its political weight, the EU confers unprecedented legitimacy on the critics of the current ISDS system and reveals investment dispute settlement in the light of public international law, breaking with its background in commercial litigation. The art…
From the banks of Upper Tigris River to the Zagros Highlands. The Tübingen Eastern Ḫabur Archaeological Survey. Trial season 2013
2016
After decades of strife and unrest, during which Northern Iraq remained closed to the outside world, a new era of international scientific enterprise has begun in this region thanks to the recent democratic and civil upturn and its subsequent economic resurgence. In the last few years, together with the restoration and refurbishment of historical monuments, there has also been a spread of new archaeological undertakings in the form of surveys and excavations, the quality and quantity of which is fully shown in the present volume. A Tübingen University research project was initiated in the northernmost part of Iraqi-Kurdistan, in the province of Dohuk. The research area is located at the foo…
Hydromechanical behaviour of a volcanic ash
2013
This paper presents experimental analysis and numerical modelling aimed at improved understanding and prediction of the hydromechanical behaviour of volcanic ash at various states of saturation. Results from a comprehensive experimental programme are presented in order to characterise the response of the material in terms of matric suction and confining stress changes. The evolution of the yield stress at different suction levels has been quantified. The volumetric response with suction variations allowed the analysis of the collapse-upon-wetting behaviour. Water retention and permeability are also addressed. Tests results are used to calibrate a constitutive model based on the effective s…
REPRESENTATIONS OF BOUNDARIES IN THE CONTEXT OF PRIVATE AND PUBLIC RELATIONSHIPS: LATVIAN EXAMPLE
2012
In social practice boundaries often have been perceived and used as a tool of structuring of the space. Spatial structures appear as representations of different activities and patterns as public and private relationships. Formal regulations, public attitudes forming on the basis of values system, acceptance and rejection of norms create different forms of individual adaptation cases which are representing in planning practise and landscape as a contradictory public and private relationships. Baltic coastal areas, Riga agglomeration, settlements structure, local suburban land transformation processes are some of the areas have been explored. What are public and private in using of space, w…
