Frontiera geografica e frontiere mentali nella «Saga di Eirik il Rosso»

2022

La «Saga di Eirik il Rosso» («Eiríks saga rauða») appartiene al gruppo delle “Family Sagas” ("Íslendinga sögur") dell’antica letteratura islandese. Essa si configura come un testo di straordinario interesse storico e antropologico perché contiene una delle più antiche narrazioni della penetrazione dei Vichinghi, prima in Groenlandia e poi nel Nuovo Continente (la cosiddetta Vinlandia), circa 500 anni prima della “scoperta” dell’America da parte di Cristoforo Colombo. Ma è anche un testo ricco di suggestioni che afferiscono alle dimensioni del magico, del meraviglioso, dell’immaginario, e insieme un’opera nella quale la “frontiera” geografica si fonde e si confonde – nella redazione scritta …

Fonds structurels, effets de débordement géographique et croissance régionale en Europe.

2008

Les fonds structurels constituent l’un des instruments financiers de la politique regionale europeenne les plus intensement utilises afin de promouvoir la convergence entre les regions des pays membres de l’Union europeenne. Cependant, de nombreuses divergences theoriques et empiriques existent dans la litterature quant a leur capacite a encourager la croissance economique des regions les plus defavorisees. Par consequent, cet article se propose de proceder a des estimations complementaires en integrant des elements nouveaux : tout d’abord, nous adoptons une approche par l’econometrie spatiale afin de prendre en compte de possibles effets de debordement geographique entre regions ; ensuite,…

A 2600-year record of past polycyclic aromatic hydrocarbons (PAHs) deposition at Holzmaar (Eifel, Germany)

2014

Polycyclic aromatic hydrocarbons (PAHs) are a proxy for climate- and human-related historical fire activity which has rarely been used beyond 1800 AD. We explored the concentration and composition patterns of PAHs together with other proxies (charcoal, C, N, S, δ13C, δ15N, and δ34S) in a sediment core of Holzmaar as indicators of variations in climate and anthropogenic activity over the past 2600 years. The concentrations of pyrogenic PAHs remained low (< 500 ng g− 1) from the pre-Roman Iron Age (600 BC) until the first significant increases to ca. 1000–1800 ng g− 1 between 1700 and 1750 AD related to regional iron production. The highest increases in pyrogenic PAH concentrations occurred w…

The Use of Stable Isotope Ratio Analysis to Trace European Sea Bass (D. labrax) Originating from Different Farming Systems

2020

This study aimed to determine whether isotopic ratio mass spectrometry (IRMS) can discriminate farmed European sea bass according to different farming systems and geographic origins. Dicentrarchus labrax of commercial size from three different rearing systems (concrete tank inland, sea cages, and extensive methods in valleys or salt works) were collected at the trading period (autumn&ndash

Less is future: landscape as the key element for the “milieux” renaissance in the former East Germany

2013

Twenty-two years ago, Germany was reunified as a single state. Waste land, pollution and empty buildings are some of the problems that the people had to face, along with radical and painful political reorganization. The strong collective reaction to these environmental and social disasters was heart-warming. Hundreds of coordinated and collective actions of renovation in open spaces were carried out. People were involved in each level of the design process in order to decide the best way to improve and promote the heritage and identity of their landscape. Halle, Dessau, Leipzig, and Berlin are some examples explained in this paper which demonstrate that these successful massive actions are …

Evolving city governance – toward smart maturity

The research group is focusing on interdiscplinary concepts of Industry 4.0/in interaction with smart city. This group is engaged in looking for a universal model of smart city maturity. The MModel4SmartCity will provide specific analysis of best practices of smart cities based on measure of level smartness, business solutions and technologies to achieve a really smart city in all dimensions. The goal is to increase knowledge on the smart city maturity measurement. The research will also contribute to the development of strategic management theory, especially in research results and tools that can support the development of smart cities in particular dimensions. The proposed concept will co…

Reproductive Medicine

Infertility, or the inability to conceive a child, is a medical condition recognized by the World Health Organization (WHO) that causes serious health problems for affected women, as well as significant epidemiological and sociological repercussions for society. It is estimated that this condition affects 15% of couples worldwide, with its incidence increasing, affecting 10% of couples who want to conceive their first child and between 10-25% of those who want to have a second child. The European Parliament's report on the future demographic of Europe (2007/2156 (INI)) highlights the need to consider infertility as a sensitive and important issue for consideration in articles 25 and 26. The…

Chemistry and technology of polymers and polymer materials

Our research covers the following main areas: (1) the design, synthesis and characterization of homogeneous and supported on inorganic carriers catalysts for coordination polymerization, (2) study of alkylaluminium ionic liquids, determination of physical properties and application as a medium of polymerization reaction, (3) evaluation of synthesized catalysts in olefin (co)polymerization, ethylene-norbornene copolymerization and cyclic esters polymerization, (4) modification of polyethylene by copolymerization of ethylene with higher olefins, polar monomers and other comonomers, (5) preparation and characterization of (nano)composites based on polymers and biopolymers with inorganic and or…
