Venuto al mondo di Margaret Mazzantini: dal testo al paratesto, e ritorno
2015
The paratext on the back cover of Margaret Mazzantini's Venuto al mondo (published in 2008, winner of Campiello Award 2009, a film in 2012, a serial tv in 2014) reports the 'prize motivation' written by the jury of Campiello, formed by important professors and literary critics. Comparing the text of the novel with the paratext of the book, the article analyses some sure results of the paratext, and also some strategic gaps and reticences.
Degradation of Lincomycin in aqueous medium: coupling of solar photocatalysis and membrane separation
2005
Abstract The photocatalytic oxidation of a common antibiotic, the lincomycin was carried out in aqueous suspensions of polycrystalline TiO 2 Degussa P25 irradiated by sunlight. In order to improve the performance of the lincomycin degradation a hybrid system consisting of a solar photoreactor with the photocatalyst in suspension coupled with a membrane module, used to confine both photocatalyst and pollutants in the reaction environment, was tested. A preliminary study was carried out in order to determine some kinetics parameters of the drug photodegradation. The influence of initial substrate concentration on the lincomycin photooxidation rate was investigated. The photooxidation rate fol…
Ordinary Muon Capture on 136Ba : Comparative Study Using the Shell Model and pnQRPA
2023
In this work, we present a study of ordinary muon capture (OMC) on 136136Ba, the daughter nucleus of 136136Xe double beta decay (DBD). The OMC rates at low-lying nuclear states (below 1 MeV of excitation energy) in 136136Cs are assessed by using both the interacting shell model (ISM) and proton–neutron quasiparticle random-phase approximation (pnQRPA). We also add chiral two-body (2BC) meson-exchange currents and use an exact Dirac wave function for the captured s-orbital muon. OMC can be viewed as a complementary probe of the wave functions in 136136Cs, the intermediate nucleus of the 136136Xe DBD. At the same time, OMC can be considered a powerful probe of the effective values of weak axi…
Tell el-'Abd II. Pottery and Potmarks at an Early Urban Settlement of the Middle Euphrates River Valley, Syria. Final Reports of the Syrian-German ex…
2013
The monograph investigates the breakdown of the Uruk world-system towards the end of the 4th millennium BCE, and the roots of secondary state formation in the Middle Euphrates region through the analysis of continuity and change in the Early Bronze ceramic material from the site of Tell el-‘Abd (Tabqa Dam, Syria). This analysis fills a chronological gap for the early third millennium, a period poorly known in the district downstream from Carchemish. It further includes the study of over 1300 potter’s marks, thus offering new insight into the intra- and inter-site organization of pottery production and into a complex and variegated system of visual communication active at a regional level be…
“Anything taking shape?” : Capturing various layers of small group collaborative problem solving in an experiential geometry course in initial teache…
2022
Collaborative problem solving (CPS) is widely recognized as a prominent 21st-century skill to be mastered. Until recently, research on CPS has often focused on problem solution by the individual; the interest in investigating how the theorized problem-solving constructs function as broader social units, such as pairs or small groups, is relatively recent. Capturing the complexity of CPS processes in group-level interaction is challenging. Therefore, a method of analysis capturing various layers of CPS was developed that aimed for a deeper understanding of CPS as a small-group enactment. In the study, small groups of teacher education students worked on two variations of open-ended CPS tasks…
Transport of Arabidopsis GPI-anchored proteins along the early secretory pathway: Role of GPI-anchor remodelling and p24 proteins
2019
Las proteínas con anclaje GPI son una familia de proteínas que están ancladas a la cara exterior de la membrana plasmática mediante un ancla GPI y se ha visto que juegan un papel clave en plantas. Sin embargo, la maquinaria molecular implicada en el transporte de estas proteínas a la membrana plasmática en plantas es aún desconocida. Las proteínas p24 tienen un papel importante en el control de calidad de proteínas (posiblemente incluyendo las proteínas con anclaje GPI) transportadas entre el Retículo Endoplasmático y el aparato de Golgi. Esta tesis doctoral tiene como objetivo el estudio de la posible implicación de las proteínas p24 en la salida del Retículo Endoplasmático y en la localiz…
'Diotiman erôs : tietäminen ja yksilöön kohdistuva halu Platonin
2015
Platonin dialogi Pidot kuvaa Sokrateen ja hänen juhlakumppaneidensa keskustelun Erôksen, rakkauden jumalan, ylistykseksi. Kirjalliselta muodoltaan rikkaan ja monivivahteisen dialogin puhujista Sokrates-hahmon asema on poikkeuksellinen. Hän lainaa mantineialaisen naisen Diotiman näkemyksiä – tämä on vihkinyt nuoren Sokrateen rakkauden saloihin. Vaikutusvaltaiseksi tulkinnaksi (analyyttisesti motivoituneessa) Platon-tutkimuksessa on muotoutunut käsitys, jonka mukaan rakkaus ei Platonilla voi kohdistua ihmisyksilöön, vaan sen todellinen kohde on kauneuden idea. Eikö yksilöiden väliselle rakkaudelle ole sijaa Platonin näkemyksessä? Onko Pitojen käsitys rakkaudesta torjuttava vanhentuneena tai f…
Growth and population structure of perch in relation to diet in a small humic lake, Valkea-Kotinen
2011
Lake Valkea-Kotinen is a long-term ecological monitoring site in the Evo region of southern Finland .The aim of this study was to investigate the growth and population structure of perch (Perca fluviatilis L.) in relation to diet in Valkea-Kotinen in order to provide reference data for a study investigating effects of increased loading of dissolved organic matter to nearby Lake Alinen Mustajärvi. Valkea-Kotinen was predominantly inhabited by small benthivorous perch. The growth relationship between opercular bone and total length of perch in the lake is similar to those earlier analysed for nearby lakes. Compared to wider growth rates, the growth of perch was slow and similar to those in si…
Metabotropic glutamate receptors activate phospholipase D in astrocytes through a protein kinase C-dependent and Rho-independent pathway.
2003
Metabotropic glutamate receptors (mGluRs) are G protein-coupled receptors that mediate phospholipase D (PLD) activation in brain, but the mechanism underlying this response remains unclear. Here we used primary cultures of astrocytes as a cell model to explore the mechanism that links mGluRs to PLD. Glutamate activated both phospholipase C (PLC) and PLD with equal potency and this effect was mimicked by L-cysteinesulfinic acid, a putative neurotransmitter previously shown to activate mGluRs coupled to PLD, but not PLC, in adult brain. PLD activation by glutamate was dependent on Ca(2+) mobilization and fully blocked by both protein kinase C (PKC) inhibitors and PKC down-regulation, suggesti…
Nitrate and nitrite in the diet: How to assess their benefit and risk for human health
2015
Nitrate is a natural constituent of the human diet and an approved food additive. It can be partially converted to nitrogen monoxide, which induces vasodilation and thereby decreases blood pressure. This effect is associated with a reduced risk regarding cardiovascular disease, myocardial infarction, and stroke. Moreover, dietary nitrate has been associated with beneficial effects in patients with gastric ulcer, renal failure, or metabolic syndrome. Recent studies indicate that such beneficial health effects due to dietary nitrate may be achievable at intake levels resulting from the daily consumption of nitrate-rich vegetables. N-nitroso compounds are endogenously formed in humans. However…
