Reventilation Episodes During the Sapropel S1 Deposition in the Eastern Mediterranean Based on Holococcolith Preservation

2019

Organic-rich layers (sapropels), preserved in eastern Mediterranean marine sediment records, represent pronounced perturbations to thermohaline circulation and environmental conditions in the basin, in response to enhanced African monsoon activity and subsequent massive freshwater discharge. During the most recent event, Sapropel S1 formed between 10.8 and 6.1 ka, when freshwater-driven stratification caused seafloor anoxia below ~1,800-m depth, as a result of both failure of deep water formation and enhanced productivity. Here we analyze coccolith assemblages from the open eastern Mediterranean that form a west-east transect across the basin and provide insights on past environmental chang…

Paternity testing of endangered species of birds by DNA fingerprinting with non-radioactive labelled oligonucleotide probes

1993

In the last years, DNA fingerprinting became the most powerful tool for identification and paternity testing in man. The success of this method encouraged the German Federal Ministry of Environment, Natural Protection and Reactor Safety to apply DNA fingerprinting in the field of protection of endangered species of birds, such as birds of prey or parrots. In the last three years, we received more than 400 blood and tissue samples of 23 species of birds of prey or parrots, most of them obtained by confiscation, to establish paternity and legal breeding success. We used digoxigenated oligonucleotide probes, mainly (GGAT)4 and (GACA)4 for hybridization. In most cases of confiscated families of…

Endocrine disrupter compounds removal in wastewater using microalgae: Degradation kinetics assessment

2018

[EN] This paper describes a study carried out to determine the removal kinetics of four micropollutants (4-tert-octylphenol (OP), technical-nonylphenol (t-NP), 4-nonylphenol (4-NP) and bisphenol-A (BPA)) usually found in wastewater streams. The kinetic experiments were carried out in batch reactors containing the effluent of an Anaerobic Membrane BioReactor (AnMBR) in the presence of light, oxygen and microalgae. As the degradation process of the studied micropollutants obeyed a pseudo-first-order kinetics, the second-order kinetics for each micropollutant was then calculated. The second order rate constants for the hydroxyl radical (k.(OH)) ranged from 7.0.10(+10) to 6.6.10(+12) L.mol(-1).…

An analysis of Italian university students' performance through segmented regression models: gender differences in STEM courses

2021

AbstractThis paper investigates gender differences in university performances in Science, Technology, Engineering and Mathematics (STEM) courses in Italy, proposing a novel application through the segmented regression models. The analysis concerns freshmen students enrolled at a 3-year STEM degree in Italian universities in the last decade, with a focus on the relationship between the number of university credits earned during the first year (a good predictor of the regularity of the career) and the probability of getting the bachelor degree within 4 years. Data is provided by the Italian Ministry of University and Research (MIUR). Our analysis confirms that first-year performance is strong…

"Vain tosirakkauden teko voi sulattaa jäätyneen sydämen" : kuinka disneyfikaatio on vaikuttanut H. C. Andersenin Lumikuningatar-satuun

2014

Tutkielman tavoitteena on tarkastella sitä, millä tavoin Disney on muuttanut Hans Christian Andersenin Lumikuningatar-satua adaptoidessaan sitä kokopitkäksi animaatioelokuvaksi Frozen - Huurteinen seikkailu. Aihetta tarkastellaan erityisesti disneyfikaation (vapaa suomennos englannin sanasta "disneyfication") käsitteen kautta.

The Road to Parnassus. Artist Strategies in Contemporary Art. Rise and Success of Glasgow artist Douglas Gordon and of the wider YBA generation

2015

How can one become a successful artist? Where should one start a career in the art world? What are useful strategies to achieve recognition in the art system? Such questions hoard in students' minds ever since entering art school and they probably chase every kind of art professional who is at an early career stage. “The Road to Parnassus” tries to understand what makes a good start in today's art world, who are influential players in the field and which strategies might apply. The swift career ascension of Glasgow artist Douglas Gordon – one of today's leading visual artists – and of the broader YBA generation that rose into worldwide prominence in the 1990s – Damien Hirst and Sarah Lucas …

L’analisi strutturale e le fasi

2019

The X13-X13.1 is one of the most considerable cubicles in the catacomb. It consists of a quadrangular funerary chamber preceded by a short dromos placed along the gallery X. The tombs are several and of different types: arcosolia for adults and children, lithic sarcophagi, pavimental graves ("formae"), and very interesting areas for ritual "refrigerium" The archaeological investigations and the structural date indicate that the duplex cubicle is the result of different phases of development, and that it was used by a numerous and wealthy family group for several generations, by the end of the fourth/beginning of the fifth to the seventh/eighth century, as it seems also indicated by the pott…
