We numerically and theoretically investigate the behavior of a granular gas driven by asymmetric plates. The injection of energy in the dissipative system differs from one side to the opposite one. We prove that the dynamical clustering which is expected for such a system is affected by the asymmetry. As a consequence, the cluster position can be fully controlled. This property could lead to various applications in the handling of granular materials in low-gravity environment. Moreover, the dynamical cluster is characterized by natural oscillations which are also captured by a model. These oscillations are mainly related to the cluster size, thus providing an original way to probe the clustering behavior. [less ▲]

During 47 days, 80 weaned pigs, allotted to 2 groups of 30 and 50 animals, were given choice simultaneously between pellets or meal distributed ad libitum in feeders equipped with an integrated watering system. The average daily weight gain was 0.4250.058 kg, without significant difference between groups, and the mean feed conversion ratio was 1.72. The mean feed intake with pellets was double that with meal (0.49 vs. 0.24 kg/head daily). However, the pellet feeders and meal feeders were occupied for the same proportion of time: the mean occupation times were 45.5 and 42.8% (30 pigs) and 62.4 and 67.3% (50 pigs), respectively. Eating pellets seems thus to take less time than eating meal. Furthermore, we have observed that animals from the larger group were eating more quickly than members of the smaller one. Even if the feed intake of pigs with pellets was twice that with meal, pigs drank more water (60% of the total water intake) using the meal feeder. Thus, with pellets, pigs don't seem to choose a close association between feed and water consumption. In conclusion, pigs prefer pellets to meal, this choice being probably partially explained by a faster ingestion. This eating speed depending also on the group size, the number of eating places should thus take into account these two parameters. [less ▲]

Background. Several chemoattractants have been measured in exhaled breath condensate (EBC) from patients with COPD. The aim of this study was to compare the eosinophil. and neutrophil chemotactic activity contained in EBC from healthy subjects and patients with COPD. Methods: EBC collected using a commercially available condenser (EcoScreen; Erich Jaeger Viasys; Hoechberg, Germany) was compared in 45 COPD patients and 65 healthy subjects. EBC chemotactic activity for eosinophils and neutrophils was assessed using microchambers (Boyden; Neuro Probe; Cabin John, MD). Chemotactic index (CI) was used to evaluate cell migration. Results: EBC from patients with COPD (C1, 2.21 +/- 0.16 [mean +/- SEM]) and healthy subjects (CI, 1.67 +/- 0.11) displayed significant neutrophil chemotactic activity (p < 0.0001 for both), which was however higher in patients with COPD (p < 0.001). Healthy smokers had a significantly raised C1 for neutrophils by comparison with healthy nonsmokers (p < 0.01) and ex-smokers (p < 0.05). Ukewise, current COPD smokers tended to have greater neutrophil C1 than COPD who stopped smoking (p = 0.08). COPD ex-smokers had raised chemotactic activity by comparison with healthy ex-smokers (p < 0.05). Anti-interleuldn-8 (10(-6) g/mL) antibodies reduced neutrophil chemotactic activity by 35.2% (p < 0.05). EBC also contained significant eosinophil chemotactic activity in healthy subjects (CI, 1.68 0.09; p < 0.0001) and patients with COPD (CI, 1.23 +/- 0.07; p < 0.01), with a significantly lower CI in patients with COPD as compared to healthy subjects (p < 0.001). Smoking did not influence eosinophil chemotactic activity in healthy subjects or patients with COPD. Conclusions: Current smoking favors neutrophil chemotactic activity. As compared to healthy subjects, EBC from patients with COPD displays a skewed chemotactic activity toward neutrophils vs eosinophils. [less ▲]

A 7-year-old, otherwise healthy Peruvian boy presented with a 3-month history of an indurated centrofacial plaque. Histologic examination revealed a granuloma containing free-living amebae tentatively identified as Balamuthia mandrillaris. The patient failed to respond to tentative treatment. He was admitted to the intensive care unit 7 months later with neurologic manifestations of granulomatous amebic encephalitis, which proved fatal. The difficulty in diagnosing this rare presentation of cutaneous amebiasis, the challenge of treating the condition, and the morbidity and high mortality associated with cerebral involvement are discussed.

This article deals with the problem of automatically es- tablishing a correspondence between two databases popu- lated independently over the years by a distribution com- pany, for instance a SCADA system and a geographical information system. This problem is abstracted as a graph matching problem, well known in the combinatorial op- timisation community. It is then casted as an integer quadratic program. An idea of achievable results on a real system is provided, and needs for approximation or decom- position algorithms are discussed. [less ▲]

Many methods have been developed in the last few decades to obtain high-quality graphene thin sheets. They are based on very different physicochemical processes. Here we demonstrate a novel one step and simple electrografting acrylate monomer method to exfoliate highly oriented pyrolytic graphite (HOPG) into thin nanoplatelets and even down to the single graphene sheet level. Among the high research activity in the area of surface modification, electrografting is a very powerful method which has received comparatively little attention. This is surprising because this technique has many attractive features for modification of conducting or semi-conducting surfaces. The main interest of the electrografting process is to solve the recurrent problem of the organic/substrates interface weakness. The electrografting warranties a robust polymer/substrates interface and offers the possibility to tailor the functionality of the grafted polymer film opening the door to a wide range of demanding technological applications. The graphene sheets obtained through electrografting process give a stable suspension in dimethyl formamide (DMF), and they can self-precipitate on the surface of substrates after adding water as an antisolvent due to their strong surface hydrophobicity. Interestingly, the continuous films obtained exhibit ultratransparency (∼98% transmittance), and the lateral size of the exfoliated graphene sheets observed by AFM ~1nm. Raman and TEM characterizations corroborate that the graphene sheets exfoliated by our electrochemical method preserve the intrinsic structure of grapheme and give preferentially monolayered graphene sheets. The electrochemical behaviour of the acrylate monomer grafted graphene sheets was evaluated in lithium-half cells with no addition of conductive additive or binder. The PAN grafted graphene dispersed in DMF was coated on Cu foil and dried in a vacuum oven at 55°C for 12h. After 200 cycles, the reversible capacity was still kept at 300mAh/g at the current density of 50mA/g. These results indicate that the prepared high quality graphene sheets possess good electrochemical performances for lithium storage. This work provides an efficient approach to obtain high-quality, cost-effective, and scalable production of “graphene ink”, which may pave a way toward future applications in lithium-ion batteries.
