La littérature concernant la consommation énergétique du broyage dans les industries minières montre que cette problématique a été, et est encore, étudiée par de nombreux auteurs. Différents modèles de broyage sont donc disponibles pour ces industries, en particulier pour le broyage des minerais. Les principaux modèles et certaines de leurs évolutions sont repris dans la présente revue. Le broyage de la biomasse quant à lui a été bien moins étudié. Quelques études ont néanmoins porté sur la mesure des consommations énergétiques engendrées par le broyage de biomasses particulières, dans des systèmes particuliers. Rares sont celles qui prennent en compte suffisamment de paramètres relatifs à la matière entrante et sortante (granulométrie, humidité, origine, etc.) ou les caractéristiques du système de broyage. Pratiquement, aucun modèle de broyage de la biomasse n’a donc été proposé. Concernant le broyage des produits densifiés, aucune donnée ne semble disponible. À la lueur des théories de broyage de l’industrie minière, cette étude propose donc les paramètres à prendre en compte pour une éventuelle modélisation du broyage de la biomasse et des produits densifiés.

In the frame of the present study, the influence of liquid viscosity on liquid holdup distribution in a packed column equipped with the modular catalytic packing Katapak-SP 11 is measured. Water and an aqueous solution of glycerine, the viscosity of which equals 10 cP, are used as feed liquids. The estimation of liquid holdup is of great interest due to its strong influence on pressure drop, on solid wetting and on heat and mass transfer coefficients. The experimental technique used is high energy X-ray tomography, which is a unique technique to visualize the local liquid distribution inside the complex structure of packings and to quantify the liquid holdup at different scales.

Objective To determinethe prevalence of spontaneous endometriosis andthe incidence of induced endometriosis after endocervical canal resection in baboons. Design Induction and follow-up of endometriosis in baboons, which is one of the primate species that develop spontaneous endometriosis. Forty-one baboons were checked for the presence of spontaneous endometriosis. We then attempted to induce endometriosis in 30 of them by endocervical canal resection. Setting Institute of Primate Research, Nairobi, Kenya, and Catholic University of Louvain, Brussels, Belgium. Animal(s) Forty-one baboons were checked for spontaneous endometriosis and 30 of them were used to develop a model of induced endometriosis. Intervention(s) A total of 41 baboons underwent diagnostic laparoscopy for 10 months. In a first step, 30 of this number subsequently underwent endocervical canal resection. In a second step, 20 of the 30 underwent uterine horn resection. Main Outcome Measure(s) Follow-up by laparoscopy. Result(s) Two of the 41 baboons were diagnosed with spontaneous endometriosis (4.8%). Twelve months after the surgical procedure to induce endometriosis, 8 of 29 animals presented with endometriotic lesions diagnosed by using laparoscopy and confirmed by histologic examination. The incidence of induced endometriosis in our model was thus 27.6%. In 2 baboons, endometriosis disappeared over time, resulting in a final rate of 20.7% (6/29). Conclusion(s) The rate of spontaneous endometriosis is very low (4.8%). Endometriosis can be induced (with a rate of just 27.6%) by endocervical canal resection to stimulate retrograde menstruation.

After selection of the 13 biodiversity variables (Sect. 2.3) based on their importance and feasibility for assessment by NFIs, responses were solicited from participating countries regarding the degree to which the variables are now assessed. Two conclusions were evident: (1) most countries currently assess most of the variables, but (2) consensus is lacking on assessment methods and necessary field crew expertise, suggesting that harmonization would require emphasis on field operations. For each of the seven essential features into which the 13 variables were grouped, more detailed assessments were conducted. For forest categories, the conclusion was that the only major difference in classification systems used by European NFIs was whether potential or actual vegetation was used to define classes. Thus, the prospects for harmonization of forest categories are considered excellent. For forest structure, the prospects depend on the variable. For tree species, the prospects are excellent because the variable is assessed in the same manner by all NFIs. For dbh and height, considerable variability in measurementthresholds were found, but otherwise the harmonization prospects are good. For social position, definitions of classes varied, but harmonized estimates of proportions for dominant, intermediate, and suppressed classes are considered possible. Prospects for harmonized estimates of layers are consideraly poorer because of different definitions, thresholds and the uncertainty associated with visual assessment methods. Harmonized estimation of forest age is impeded by the increasing proportion of uneven-aged stands for which age is often not assessed, different definitions, and different assessment methods. However, agreement on dominant age as a reference definition would greatly increase the prospects. Deadwood is becoming an increasingly popular indicator of sustainable forest management. Unfortunately, considerable variability was found in deadwood definitions, components (e.g., stumps, limbs), sampling methods, and measurement thresholds. Thus, harmonized deadwood estimation will require development of bridges. Harmonization of regeneration estimates faces challenges due to differences in assessment approaches such as presence/absence versus coverage and all species versus dominant species. Harmonized estimation may be restricte to change in regeneration success. Harmonized estimation for ground vegetation also faces serious challenges due to differences in the components assessed (e.g., small trees, shrubs, herbs, bryophytes, lichens), difference in height thresholds, and differences in categories for which ground vegetation is reported. Forest naturalness integrates many of the other essential feature. However, many countries do not assess naturalness, and among those that do, assessment variables, methods, and reporting classes vary considerably. For harmonized assessment using NFI variables, the hemeroby approach, which emphasizes indications of human influence, is extremely sensitive to plot size. Harmonization using the ecosystem processes approach requires a common dbh threshold and similar plot sizes. The overall conclusion is that harmonization will be considerably easier for some essential features than for others. The factors leading to difficulties often are related to different definitions, different reporting classes, different measurement thresholds, and different features of sampling protocols such as plot sizes and configurations. Nevertheless, construction of reference definitions and bridges greatly facilitate harmonization for all essential features as is illustrated in Chap. 5. [less ▲]

Classic financial agency theory recommends compensation through stock options rather than shares to induce risk neutrality in otherwise risk averse agents. In an experiment, we find that subjects acting as executives do also take risks that are excessive from the perspective of shareholders if compensated through options. Compensation through restricted company stock reduces the uptake of excessive risks. Even under stock-ownership, however, experimental executives continue to take excessive risks—a result that cannot be accounted for by classic incentive theory. We develop a basic model in which such risk-taking behavior is explained based on a richer array of risk attitudes derived from Prospect Theory. We use the model to derive hypotheses on what may be driving excessive risk taking in the experiment. Testing those hypotheses, we find that most of them are indeed borne out by the data. We thus conclude that a prospect-theory-based model is more apt at explaining risk attitudes under different compensation regimes than traditional principal-agent models grounded in expected utility theory.

Recent evidence shows hydro-alcoholic solutions are more efficient than traditional medicinated soaps in the presurgical hand antisepsis of human surgeons. However, little veterinary literature is available on the subject. The aims of this study were to compare the efficiency of medicinated soaps and a hydro-alcoholic solution prior to surgery using an in use testing method in a veterinary setting. A preliminary trial was performed that compared the mean Log10 number of bacterial colony forming units (CFU) and the reduction factors (RF) between 2 five-minute hand-scrubbing sessions using different soaps (povidone iodine (PVP) and chlorhexidine gluconate (CHX)) and the 1.5-min application of a hydro-alcoholic rub (Sterillium). A clinical in use trial comparing mean log10 number of bacterial CFU’s and RF for Sterillium and CHX soap was performed in a surgical set-up. Sampling was performed using finger printing on agar plates. Sterillium and CHX had a similar immediate effect, although the sustained effect was significantly better for Sterillium. PVP showed a significantly lower immediate and sustained effect. Sterillium showed good efficiency in the clinical trial. This study shows that, as previously reported for human medicine, Sterillium can safely be considered as an attractive alternative method for surgical hand antisepsis in a veterinary surgical setting.

We study the maximum weighted independent-set problem on interval graphs with uncertainty on the vertex weights. We use the absolute robustness criterion and the min-max regret criterion to evaluate solutions. For a discrete scenario set, we nd that the problem is NP-hard for each of the robustness criteria; we also provide pseudo-polynomial time algorithms when there is a constant number of scenarios and show that the problem is strongly NP-hard when the set of scenarios is unbounded. When the scenario set is a Cartesian product, we prove that the problem is equivalent to a maximum weighted independent-set problem on the same interval graph but without uncertainty for the rst objective function and that the scenario set can be reduced for the second objective function.

Recurrent laryngeal neuropathy (RLN) is a major upper-airway disease of horses that causes abnormal respiratory noise during exercise and can impair performance. Etiopathogenesis remains unclear but genetic factors have been suspected for many decades. The objective of this study was to identify risk loci associated with RLN. To that end we genotyped 234 cases (196 Warmbloods, 20 Trotters, 14 Thoroughbreds, and 4 Draft horses), 228 breed-matched controls, and 69 parents with the Illumina Equine SNP50 BeadChip. Using these data, we quantified population structure and performed single-marker and haplotype-based association studies, as well as family-based linkage analyses. We accounted for population stratification by modeling a random polygenic background effect with covariance structure estimated from genome-wide SNP data. Using the haplotype-based approach, we identified two genome-wide suggestive loci in Warmbloods, respectively on chromosomes 21 (p = 1.62 x 10(-6)) and 31 (p = 1.69 x 10(-5)). The two signals were driven by the enrichment of a "protective" haplotype in controls compared to cases. [less ▲]

In this paper a low order partial hybrid stress solid-shell element based on the composite energy functional for the analysis of laminated composite structures is presented. This solid-shell element has eight nodes with only displacement degrees of freedoms, and three-dimensional constitutive models can be directly employed in the present formulation without any additional treatment. The assumed interlaminar stress field provides very accurate interlaminar stress calculation through the element thickness. These elements can be stacked on top of each other to model multilayer structures, fulfilling the interlaminar stress continuity at the interlayer surfaces and zero traction conditions on the top and bottom surfaces of the laminate. The present solid-shell does not show the transverse shear, trapezoidal and thickness locking phenomenon. [less ▲]
