Strong stabilization of amorphous calcium carbonate emulsion by ovalbumin: gaining insight into the mechanism of 'polymer-induced liquid precursor' p…
2011
8 pages; International audience; The impact of the ovo proteins ovalbumin and lysozyme-present in the first stage of egg shell formation-on the homogeneous formation of the liquid amorphous calcium carbonate (LACC) precursor, was studied by a combination of complementing methods: in situ WAXS, SANS, XANES, TEM, and immunogold labeling. Lysozyme (pI = 9.3) destabilizes the LACC emulsion whereas the glycoprotein ovalbumin (pI = 4.7) extends the lifespan of the emulsified state remarkably. In the light of the presented data: (a) Ovalbumin is shown to behave commensurable to the 'polymer-induced liquid precursor' (PILP) process proposed by Gower et al. Ovalbumin can be assumed to take a key rol…
Overcoming Postmodernity? Reconsidering Animal Life from Heidegger to Derrida
2018
In this paper, I would like to approach the question of language as crucial for the difference between human and non-human animals in the scenario cast by contemporary continental philosophy. I would also like to use this and other topics as a chance to take some general considerations on postmodernity into account, the latter intended as the historical condition in which we are supposed to live.
Isotopic ordering in eggshells reflects body temperatures and suggests differing thermophysiology in two Cretaceous dinosaurs
2015
International audience; Our understanding of the evolutionary transitions leading to the modern endothermic state of birds and mammals is incomplete, partly because tools available to study the thermo-physiology of extinct vertebrates are limited. Here we show that clumped isotope analysis of eggshells can be used to determine body temperatures of females during periods of ovulation. Late Cretaceous titanosaurid eggshells yield temperatures similar to large modern endo-therms. In contrast, oviraptorid eggshells yield temperatures lower than most modern endotherms but B6 °C higher than co-occurring abiogenic carbonates, implying that this taxon did not have thermoregulation comparable to mod…
Changes in eggshell ultrastructure of Falco naumanni and Tyto alba exposed to pesticides and polychlorinated biphenyls (PCBs)
2014
Changes in the quality of eggs of birds exposed to environmental contaminants have been described, but few reports concern eggshell ultrastructure. In this study, infertile or addled Lesser Kestrels (Falco naumanni) and Barn owls (Tyto alba) eggs were collected from the polluted area of Gela plain (Sicily) during 2007, and compared in terms of organophosphate and organochlorine pesticides, and PCBs levels, and eggshell ultrastructure as determined by scanning electron microscopy. Pesticide and PCB residues in eggs were determined by Gas chromatography/ mass spectrometry (GC/MS) [GC Agilent 7890A/MS Agilent 5975C (Agilent technologies) using a DB-5 capillary column in the selected ion monito…
En studie av de faktorer som bidrar til effekter ved PDAbruk i norsk hjemmesykepleie
2006
Masteroppgave i informasjonssystemer 2006 - Høgskolen i Agder, Kristiansand Helsesektoren i Norge er en belastet sektor som skal betjene et økende antall hjemmeboende klienter og bistå dem med helsetjenester og hjelp til daglige gjøremål. Etaten sliter med lav bemanning og begrensede midler. Dette har bidratt til at man har fått fremvekst av moderniseringstiltak i sektoren. Moderniseringen kan ta flere former og denne oppgaven ser i hovedsak på bruk av PDAer i norsk hjemmesykepleie. PDAer er små håndholdte PC-er som kan gi mobil tilgang til informasjon som tidligere var papirbasert og utilgjengelig for pleiepersonell ute på mobile oppdrag. Det er en rekke potensielle effekter ved slike PDA-…

Reconstruction of the internal structure of the pore system of a complex dinosaur eggshell (Megaloolithus siruguei)
2013
Despite the many reconstructions of fossil material that have recently appeared in the literature, dinosaur eggshells have never been reconstructed using computing techniques. Using the EMAC 3-D modelling methodology, we reconstruct a section of the Late Cretaceous Megaloolithus siruguei eggshell, which has a particularly complex pore system, exhibiting an intricate network of vertical, oblique, and horizontal pores.
Apprendistato parigino
2012
La mitologia della città di Parigi ritorna nelle due tarde opere cailloisiane tradotte in questo volume, Petit guide du xve arrondissement à l’usage des fantomes (1977) e Apprentissage de Paris (1978), nella forma di una scrittura non più meramente saggistica ma romanzesca e/o autobiografica. Per Caillois la lenta scoperta della “Babilonia moderna” diventa dunque inseparabile dalla conoscenza di se stesso e dalla relativa narrazione, è un percorso che arricchisce una vita intera e che si dimostrerà una componente indispensabile della scrittura autobiografica. L’architettura destinata ad accogliere i fantasmi che Caillois osserva nelle sue passeggiate parigine è dunque espressione del "fanta…
