Neuroethics 1995-2012. A bibliometric analysis of the guiding themes of an emerging research field
2016
International audience; In bioethics, the first decade of the twenty-first century was characterized by the emergence of interest in the ethical, legal and social aspects of neuroscience research. At the same time an ongoing extension of the topics and phenomena addressed by neuroscientists was observed alongside its rise as one of the leading disciplines in the biomedical science. One of these phenomena addressed by neuroscientists and moral psychologists was the neural processes involved in moral decision-making. Today both strands of research are often addressed under the label of neuroethics. To understand this development we recalled literature from 1995 to 2012 stored in the Mainz Neu…
L' entreprise, son projet, sa gouvernance : éléments d'une vision partenariale
2015
International audience; Cet article souhaite contribuer à une théorie "gestionnaire" de la firme autour de trois questions fondamentales : la finalité de l'entreprise, sa gouvernance et son ancrage institutionnel (et ses enjeux sociétaux). Les auteurs partent du principe que l'entreprise doit être appréhendée comme une action collective. Lieu de coopération(s), la firme se comprend et s'analyse comme un (ou des) projet(s) qui fédère(ent) ses acteurs internes ou externes, ses fameuses parties prenantes. Cela implique d'adopter une perspective partenariale et cognitive en matière de gouvernance si l'on veut rendre compte convenablement de l'ensemble des mécanismes à l'oeuvre en la matière.

Determining IPO prices for innovative firms: the case of young French bio-medtech firms
2020
International audience; The large number of French biotech firms that have recently gone public prompts us to analyse the role and characteristics of their initial backers and their influence in determining the offer price at the time of the IPO. We assume the offer price is setso as to underprice companies in conjunction with the exit motives of their main shareholders and the nature and characteristics of the venture capital firms backing them. The paper characterizes listed bio-medtech firms, although the resultssometimes fail to reveal underpricing for the 39 bio-medtech firms that went public on Euronext Paris between 2010 and 2016.
Strategic drivers influencing the governance of inter-firm relationships between biotechnology and pharmaceutical companies: an empirical survey
2010
This paper investigates the drivers influencing the choice of the governance form in inter-firm relationships (IFRs) between pharmaceutical and biotech companies. By analyzing the relevant literature on the issue, we have located the main drivers that might influence such relationship and a set of hypotheses linking them to governance forms. Such theoretical framework has been empirically tested through a survey conducted among the companies associated to Farmindustria. The result of the empirical analysis provides some interesting insights on how shaping bio-pharmaceutical deals; we found that the developmental stage of the product object of the deal, the existence of previous collaboratio…
Enhancing methane production from lignocellulosic biomass by combined steam-explosion pretreatment and bioaugmentation with cellulolytic bacterium
2017
Background Biogas production from lignocellulosic biomass is generally considered to be challenging due to the recalcitrant nature of this biomass. In this study, the recalcitrance of birch was reduced by applying steam-explosion (SE) pretreatment (210 °C and 10 min). Moreover, bioaugmentation with the cellulolytic bacterium Caldicellulosiruptor bescii was applied to possibly enhance the methane production from steam-exploded birch in an anaerobic digestion (AD) process under thermophilic conditions (62 °C). Results Overall, the combined SE and bioaugmentation enhanced the methane yield up to 140% compared to untreated birch, while SE alone contributed to the major share of methane enhancem…
Anaerobic and sequential anaerobic-aerobic treatments of municipal landfill leachate at low temperatures
1996
Abstract Anaerobic treatment of municipal landfill leachate (COD 1–4 g l −1 , NH 4 -N c. 0.16 g l −1 ) was studied at 11 and 24°C by using laboratory-scale UASB and hybrid reactors. Aerobic post-treatment of the anaerobically treated leachate was also studied at 24°C using an activated-sludge process. In the 11°C reactors, a COD removal of up to 60–65% was obtained with 1.5-2 day HRT and 0.7-1.5 kg COD m −3 day −1 organic loading rates. At 24°C, a COD removal of up to 75% was achieved with a 10 h HRT. The highest organic loading rate applied was 10 kg COD m −3 day −1 at 24°C. Inorganic material accumulated in the reactor sludges at both temperatures. However, the specific methanogenic activ…
Use of rumen microorganisms to boost the anaerobic biodegradability of microalgae
2017
[EN] A laboratory bioreactor using rumen microorganisms to treat Scenedesmus spp. biomass was operated for 190 days. At first the bioreactor operated as a Rumen-like Fermenter (RF) with a Sludge Retention Time (SRT) of 7 days. The RF was subsequently transformed into an anaerobic digestion system including two configurations: continuously-stirred tank reactor and anaerobic membrane bioreactor in which different SRT values of up to 100 days were assessed. Methane production peaked at 214 mL CH4 g−1 CODIn with a SRT of 100 days. COD removal and BDP peaked at above 70% and 60%, respectively, at the highest SRT, with no pre-treatment prior to microalgae digestion. The waste sludge product…
Effect of simulated gastrointestinal digestion on sialic acid and gangliosides present in human milk and infant formulas.
2011
The effects of simulated gastrointestinal digestion upon sialic acid and gangliosides in infant and follow-on formulas and human milk, as well as their bioaccessibility, have been evaluated. The gastric stage is the step that causes a greater decrease in sialic acid and ganglioside contents. The intestinal stage only decreases the total and individual contents of gangliosides. After gastrointestinal digestion, neither sialic acid nor gangliosides were found in the nonbioaccessible fraction. The highest bioaccessibility (100 × content in soluble fraction after gastrointestinal digestion/total content) of sialic acid is found in human milk (87%), followed by infant formula (77%) and follow-on…
