Modelling hydrolysis: Simultaneous versus sequential biodegradation of the hydrolysable fractions
2018
Hydrolysis is considered the limiting step during solid waste anaerobic digestion (including co-digestion of sludge and biosolids). Mechanisms of hydrolysis are mechanistically not well understood with detrimental impact on model predictive capability. The common approach to multiple substrates is to consider simultaneous degradation of the substrates. This may not have the capacity to separate the different kinetics. Sequential degradation of substrates is theoretically supported by microbial capacity and the composite nature of substrates (bioaccessibility concept). However, this has not been experimentally assessed. Sequential chemical fractionation has been successfully used to define i…
Modeling small‐scale cassava starch extraction. Simulation of the reduction of water consumption through a recycling process
2010
International audience; The purpose of this study was to model the extraction unit operation of the cassava starch manufacturing process and to propose a realistic recycling simulation in order to reduce the volumes of effluents. The model was developed from reactors which are commonly used for cassava starch extraction at a household scale in Vietnam. The reactors were tested using inflow starch as a marker at the beginning of the batch process. The experimental residence time distribution (RTDexp) was calculated by the outflow of the starch concentration. Using Matlab®, the RTDexp was compared to the theoretical residence time distribution (RTDth). The dynamic model obtained was built up …
Développement et évaluation d'une méthode fondée sur la PCR temps réel pour la caractérisation des bioaérosols : application au groupe des actinomycè…
2013
Actinomycetes are ubiquitous bacteria and some can be potentially pathogen for Humans in the air of some working areas. It’s notably the case in composting plants where bacteria concentrations can reach high values. Workers exposure to these inhalable bioaerosols can be source of various diseases (hypersensitivity pneumonitis notably). Although this problem is admitted, bibliography reveals a lack of knowledge about risk assessment: currently, none global method for bioaerosols sampling and analysis is standardized. So much that neither dose-effects relationship for most of these bacteria, nor Threshold Limit Value exists. Traditional methods, that are used, have some drawbacks (concentrati…

Twin Peaks: Fire Walk With Me (1992) and David Lynch's Aesthetics of Frustration
2010
This article focuses on Twin Peaks: Fire Walk With Me (David Lynch,1992), the prequel to the TV series produced by Mark Frost and David Lynch (1990-1991), which represents a turning point in Lynch's filmography. The author argues that the film's aesthetics frustrate viewer expectations, and especially the fan of the TV series, by addressing the issue of the film's relation to the TV series. Special attention is payed to the aesthetics of time passing and to the accumulation of unusual signs in the first part of the film, with reference to Deleuze and Michel Guiomar, and the way they lead the spectator, fan or neophyte, to expect something Fantastic to happen. The article then addresses the …
"More or Less American: Sergio Leone's Vision of America in 'Once Upon a Time in the West' (1968)"
2012
This article focuses on the representation of the American West in Sergio Leone's fourth Western, which is the first to include several scenes that have been shot on location in the U.S. The author argues that Once Upon a Time in the West offers a critique not only of the classical Hollywood Westerns Leone adored, but also of his own brand of Italian Western, which may, in part, explain why members of the counter-culture were so enthused by the film at its release. The first section examines the way the use of American locations foregrounds the artificiality of Leone's spatial construction. The second explores the political implications of the inclusion of various minority groups, thereby r…
Temporal-range estimation of multiple objects: evidence for an early bottleneck.
2011
When making parallel time-to-contact (TTC) estimates of two approaching objects, the two respective TTC estimates interfere with one another in an asymmetric fashion. The TTC of the later-arriving object is systematically overestimated, while the estimated TTC for the first-arriving object is as accurate as in a condition presenting only a single object. This asymmetric interference points to a processing bottleneck that could be due to early (e.g., during the estimation of the TTC from the optic flow) or late (e.g., during the timing of the response or the motor execution) constraints in the TTC estimation process. We used a Sperling-like prediction-motion task to differentiate between the…
Neighborhood resources associated with active travel in older adults: A cohort study in six European Countries
2020
Objectives: To study associations between perceived neighborhood resources and time spent by older adults in active travel. Methods: Respondents in six European countries, aged 65–85 years, reported on the perceived presence of neighborhood resources (parks, places to sit, public transportation, and facilities) with response options “a lot,” “some,” and “not at all.” Daily active travel time (total minutes of transport-related walking and cycling) was self-reported at the baseline (n = 2,695) and 12–18 months later (n = 2,189). Results: Reporting a lot of any of the separate resources (range B’s = 0.19–0.29) and some or a lot for all four resources (B = 0.22, 95% confidence interval [0.09, …
Asymptomatic Amyloidosis at the Time of Diagnostic Bone Marrow Biopsy in Newly Diagnosed Patients with Multiple Myeloma and Smoldering Multiple Myelo…
2009
Abstract Abstract 2803 Poster Board II-779 Background. The rate of asymptomatic amyloidosis (asym-amyloidosis) detected in patients with newly diagnosed multiple myeloma (MM) or smoldering multiple myeloma (SMM) is unknown. This topic is significant because unrecognized AL may be associated with increased mortality may change the patient's management. The objective of the present investigation was to evaluate the number and clinical significance of asym-amyloidosis in MM and SM patients at the time of the diagnostic bone marrow (BM) biopsy for MM. Materials and Methods. The study population was selected from the Mayo Clinic Dysproteinemia database and consisted of consecutive patients with …
High frequency rTMS over the left parietal lobule increases non-word reading accuracy
2012
Increasing evidence in the literature supports the usefulness of Transcranial Magnetic Stimulation (TMS) in studying reading processes. Two brain regions are primarily involved in phonological decoding: the left superior temporal gyrus (STG), which is associated with the auditory representation of spoken words, and the left inferior parietal lobe (IPL), which operates in phonological computation. This study aimed to clarify the specific contribution of IPL and STG to reading aloud and to evaluate the possibility of modulating healthy participants' task performance using high frequency repetitive TMS (hf-rTMS). The main finding is that hf-rTMS over the left IPL improves non-word reading accu…
