Activity-based Management in France: A focus on the information systems department of a bank
2011
International audience; The aim of the paper is to describe the Activity-based Costing and Management methods applied in France. For that purpose, we use a literature review and a case study. In a first time, we analyse the origins of the methods and their diffusion. Then we present the French situation. Finally, we propose a case study that takes place in a French bank. Our paper shows that the ABC and ABM methods are as developed in France as in the Anglo-Saxon countries and that the methods are strategically oriented.
La pianificazione ai fini della valorizzazione delle risorse legnose in Sicilia: un caso di studio su popolamenti di castagno dei Nebrodi
2019
In Sicily, forest planning still has too many gaps. This study proposes both to make a contribution to the current cognitive framework of the Nebrodi chestnut groves, and to draw up a management plan that is still lacking in order to identify forestry addresses and sustainable management necessary to maintain and defend these forest formations.

Entrepreneurs (novices vs. experts) and investors: Interaction and rationality dynamics (effectual vs. causal)
2019
The paper studies the mechanisms that govern the interactions between the entrepreneur (novice or expert) and the specific investors of emerging firms (business angels (BAs) and venture-capital firms (VCs)). Combining both literatures on entrepreneurship and entrepreneurial finance, our aim is to understand if the rationalities of these three actors help them or not to interact, and, to study how they influence each other during the firm's growth. In order to do so, we undertake two processual case studies. Our results show that effectual rationality underlines the interaction between the entrepreneur and the BAs at the creation of the firm, whilst causal rationality is helpful in the searc…
Die aufschlußfreie Bestimmung von Schwermetallen (Zn, Cd, Pb, Cu) in Getränken (Wein) durch inverse Voltammetrie in einer Durchflußzelle
1987
Digestion-free determination of trace-metals (Zn, Cd, Pb, Cu) in beverages by inverse voltammetry in a flow-through cell equipped with a mercury film-electrode is described. Optimal enrichment potentials are obtained by inspection of the pseudopolarograms of the elements in the original diluted sample solution. After the deposition step in the untreated sample solution stripping is effected in a proper supporting electrolyte after medium exchange. Values obtained by this techniques with various samples compare well with those obtained by usual procedures including wet digestion of the samples.
The mechanism of the antioxidant effect of smoked paprika from La Vera, Spain
2013
This study aimed at further investigating the antioxidant effect of smoked paprika (Pimenton La Vera, Spain) in healthy subjects. Crossover study included male students (age 20.6 ± 1.7 years) who consumed smoked or non-smoked paprika (2 g/day, 20 times, over 30 days). After ingestion of smoked paprika, plasma malondialdehyde (MDA) levels were significantly (p < 0.01) reduced versus basal and non-smoked paprika ingestion values. Reduced glutathione (GSH) levels were increased and oxidised glutathione (GSSG) levels reduced significantly (p < 0.05) in paired subjects after consumption of smoked paprika. Smoked paprika significantly increased mRNA levels of glutathione peroxidase and cytochrome…
Characterization of the DNA-binding activity of the E1 and E2 proteins and the E1/E2 complex of human papillomavirus type 33.
1997
The E1 and E2 proteins of papillomaviruses are essential for the initiation of viral DNA replication. We have purified the E2 protein of human papillomavirus type 33 (HPV-33) by immunoaffinity chromatography. The purified E2 protein bound with high affinity to all four consensus binding sites of HPV-33 (Kd approximately equal to 2 x 10(-10)M). A putative E2 binding site differing at one position in the second stem of the palindrome was not bound by E2. The E1 protein of HPV-33 purified by affinity chromatography using glutathione S-transferase as tag displayed specific DNA-binding activity in footprint analyses protecting HPV-33 nucleotides 7896 to 7909/1 to 18 from DNasel digestion. Hypers…
Hypertriglyceridemia and Omega-3 Fatty Acids
1988
Recent studies by Bang and Dyerberg (1) have stimulated interest in the metabolism of omega-3 fatty acids and have suggested a link between the ingestion of these fatty acids in a diet and the low death rate from athersclerotic disease in Eskimos. In Japan, where fish consumption has traditionally been high, a concommitant shift in tissue lipid consumption favouring omega-3 polyunsaturated fatty acids has been interpreted as causative of a relatively low incidence of cardiovascular disease (1). When analyzing Eskimo food consumption, it became clear that the consumption of omega-3 PUFA is much higher besides a 50% reduction of saturated fat and a relatively high content of monounsaturated f…
Absorption and intestinal catabolism of fatty acids in the rat: effect of chain length and unsaturation
1991
Simultaneous portal blood absorption and intestinal mucosal catabolism of labelled fatty acids were investigated. Anaesthetized adult Wistar rats were infused intraduodenally either with 90 mumol of capric (C10:0), oleic (C18:1), linoleic (C18:2) or arachidonic (C20:4) 1-14C acids or with 30 mumol of each labelled fatty acid in addition to 30 mumol of oleic acid and 30 mumol of monopalmitin. For mixed infusates, experiments were carried out with two additional long-chain fatty acids: palmitic (C16:0) and erucic (C22:1) 1-14C acids. Radioactivity was quantified in the lipids and in the catabolic products in portal blood recovered at 5 min intervals for 1 h after infusion. At the end of the e…
Exploring the limits of anaerobic biodegradability of urban wastewater by AnMBR technology
2018
[EN] Anaerobic membrane bioreactors (AnMBRs) can achieve maximum energy recovery from urban wastewater (UWW) by converting influent COD into methane. The aim of this study was to assess the anaerobic biodegradability limits of urban wastewater with AnMBR technology by studying the possible degradation of the organic matter considered as non-biodegradable as observed in aerobic membrane bioreactors operated at very high sludge retention times. For this, the results obtained in an AnMBR pilot plant operated at very high SRT (140 days) treating sulfate-rich urban wastewater were compared with those previously obtained with the system operating at lower SRT (29 to 70 days). At 140 days SRT the …
