Electrical Transport Phenomena of Single ZnO Nanowire Device Directly Measured Using Nano Manipulator
Authors: Yoon Sang Won , Seo Jong-Hyun , Seong Tae-Yeon , Kwon Hoon , Lee Kon Bae , Ahn Jae-Pyoung 
Published: September 2010

AbstractZnO nanowire (NW) has potential applications for transparent electrodes, gas sensors, nanoscale optoelectronic devices, piezoresponse force microscopy (PFM) and field effect transistors. In general, we have evaluated the electrical properties of nanowire device from I-V curves measured mainly from the bundle-like ensemble structure of ZnO, not individual ZnO NWs. Most applications require details on the electrical mobility of ZnO NWs. Recently, the electrical transport of single ZnO NWs has been studied only from several devices fabricated by electron-beam lithography. However their I-V curves categorized into three types of resistance, i.e., symmetrical, rectifying and linear shapes due to contact problems between ZnO NWs and electrodes, results in contradictory.In this paper, we manufactured single NW device using an individual ZnO nanowire, of which the junctions were made by Pt deposition using a focused ion beam (FIB), and performed RTA processes. The single ZnO NW device consists of ZnO-Pt, ZnO-Au and Au-Pt junctions. The electrical transport of the single ZnO NW device was investigated by directly measuring the electrical resistance using nano manipulators from cross-sectioned devices. The device showed a typical Ohmic contact in I-V curves and the resistance was decrease with the RTA temperature. The CL (Cathodoluminescence) and EDS in TEM (Energy dispersive spectroscopy in transmission electron microscopy) measurements were also performed to evaluate the crystallinity (defect level) and chemical composition at the center and edge of the cross-sectioned ZnO NWs. From the results, we found that lots of defects were stored at the surface of ZnO NW and impurities at the junction were abruptly reduced. Therefore, the electrical transport of the single ZnO NW device depends strongly on the crystallinity of the ZnO NW and the C content at the Pt junction. From the electrical transport measured on the cross sectioned device, the ZnO-Au junction acted as the fastest transport path among ZnO-Pt, ZnO-Au and Au-Pt junctions in the single ZnO NW device.
A Critical Assessment of RNA-Mediated Materials Synthesis
Authors: Franzen Stefan , Leonard Donovan 
Published: September 2010

AbstractRNA- and DNA-mediation or templating of materials has been used to synthesize nanometer scale wires, and CdS nanoparticles. However, RNA and DNA have the potential to act as catalysts, which could be valuable tools in the search for new routes to materials synthesis. RNA has the ability to catalyze splicing and cutting of other RNA molecules. Catalytic activity has been extended to more general classes of reactions for both RNA and DNA using in vitro selection methods. However, catalytic activity in materials synthesis is a more recent idea that has not yet found great application. The first example of RNA-mediated evolutionary materials synthesis is discussed with specific data examples that show incompatibility of reagents in the solvent system utilized. The hydrophobic reagent Pd2(DBA)3, used as a metal precursor, was observed to spontaneously form nanostructures composed of Pd2(DBA)3 or Pd(DBA)3 rather than palladium nanoparticles, as originally reported 1. A case study of this materials synthesis example is described including the complimentary use of multi-length scale techniques including transmission electron microscopy (TEM), selected area electron diffraction (SAED), scanning TEM (STEM), electron energy loss spectroscopy (EELS), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and optical microscopy (OM). This example raises important questions regarding the extent to which non-aqueous solvents should be used in nucleic acid-mediated processes, the nature of selections in enzyme and materials development, and the requirement for chemical compatibility of the precursor molecules. The importance of good characterization tools at every stage of an in vitro selection is illustrated with concrete examples given. In order to look at the way forward for nucleic acid-mediated materials synthesis, an examination of the chemical interaction of nucleic acids with various precursors is considered. Application of density functional theory calculations provides one means to predict reactivity and compatibility. The repertoire of chemical interactions in the nucleic acids is considered vis-à-vis common metals and metal chalcogenides. The case is made for the need for water-soluble syntheses and well-controlled kinetics in order to achieve the control that is theoretically possible using nucleic-acids as a synthetic tool.
Experimental investigations into the mechanical properties of the collagen fibril-noncollagenous protein (NCP) interface in antler bone
Authors: Hang Fei , Barber Asa H 
Published: September 2010

AbstractAntler is an extraordinary bone tissue that displays significant overall toughness when compared to other bone materials. The origin of this toughness is due to the complex interaction between the nanoscale constituents as well as structural hierarchy in the antler material. Of particular interest is the mechanical performance of the interface between the collagen fibrils and considerably smaller volume of non-collagenous protein (NCP) between these fibrils. This paper directly examines the mechanical properties of isolated volumes of antler using combined in situ atomic force microscopy (AFM)-scanning electron microscopy (SEM) experiments. The antler material at the nanoscale is approximated to a fiber reinforced composite, with composite theory used to evaluate the interfacial shear stresses generated between the individual collagen fibrils and NCP during mechanical loading.
Continuous Reservoir-Simulation-Model Updating and Forecasting Improves Uncertainty Quantification
Authors: Liu Chang , McVay Duane A. 
Published: September 2010

Summary
Most reservoir-simulation studies are conducted in a static context—at a single point in time using a fixed set of historical data for history matching. Time and budget constraints usually result in significant reduction in the number of uncertain parameters and incomplete exploration of the parameter space, which results in underestimation of forecast uncertainty and less-than-optimal decision making. Markov Chain Monte Carlo (MCMC) methods have been used in static studies for rigorous exploration of the parameter space for quantification of forecast uncertainty, but these methods suffer from long burn-in times and many required runs for chain stabilization.
In this paper, we apply the MCMC in a real-time reservoirmodeling application. The system operates in a continuous process of data acquisition, model calibration, forecasting, and uncertainty quantification. The system was validated on the PUNQ (production forecasting with uncertainty quantification) synthetic reservoir in a simulated multiyear continuous-modeling scenario, and it yielded probabilistic forecasts that narrowed with time. Once the continuous MCMC simulation process has been established sufficiently, the continuous approach usually allows generation of a reasonable probabilistic forecast at a particular point in time with many fewer models than the traditional application of the MCMC method in a one-time, static simulation study starting at the same time.
Operating continuously over the many years of typical reservoir life, many more realizations can be run than with traditional approaches. This allows more-thorough investigation of the parameter space and more-complete quantification of forecast uncertainty. More importantly, the approach provides a mechanism for, and can thus encourage, calibration of uncertainty estimates over time. Greater investigation of the uncertain parameter space and calibration of uncertainty estimates by using a continuous modeling process should improve the reliability of probabilistic forecasts significantly.
A New Methodology To Safely Produce Sand-Controlled Wells With Increasing Skin
Authors: Chitale Ashish A. , Stein Michael H. , Arias Brian J. , Narayanan Ram K. , Schott David W. 
Published: September 2010

Summary
Monitoring deepwater Gulf of Mexico (DW GOM) wells with gravel-pack and frac-pack completions is an increasingly challenging task. Wells often experience increasing skin, adding to the risk of completion failure. Historically, sand-control completions have experienced a 15% rate of sand-related completion failure (King et al. 2003). The industry tends to evaluate safe target rates qualitatively as skin increases. Reducing the flow rate entirely on the basis of an increase in global skin can be too conservative and can overrestrict target rate. Thus, it is important to know which components of the increase in skin can cause the completion to fail. Furthermore, it is not well understood how to quantify a safe target rate with the increased skin.
This paper will present a new methodology to evaluate the components of skin increase that could cause sand-control completions to fail. The failure mechanism we address is perforation plugging by movement of fines and sand. Our new methodology helps to quantify the risk and convert it into a safe target rate. This paper will also present case studies of oil and gas wells in the Na Kika asset in DW GOM where this methodology was applied successfully.
The well completions are monitored with BP's flux-based approach (Tiffin et al. 2003; Stein et al. 2005; Keck et al. 2005). In all cases, the wells experienced increased skin, causing the engineers to choke back the wells. The analysis showed that some of the skin increase was because of multiphase effects as the reservoir pressure was below the saturation pressure. We also determined which skin components likely caused perforation plugging, thereby increasing the completion flux. Accounting for multiphase-flow effects resulted in a higher safe-operating rate limit than with a conventional analysis. The results allowed the Na Kika asset to produce these wells at their maximum allowable safe-operating rate with the higher skin while producing within BP's flux-based guidelines.
Growing Trend of China’s Contribution to the Field of Rheumatology 2000–2009: A Survey of Chinese Rheumatology Research
Authors: CHENG TAO , ZHANG XIANLONG 
Published: September 2010

Objective.In the past decade, rheumatology in China has achieved great advances. However, scientific publications on rheumatology in the 3 major regions of China — Mainland (ML), Hong Kong (HK), and Taiwan (TW) — are unknown. We assessed the performance of rheumatology research in China from 2000 to 2009.Methods.Twenty-two journals included in the rheumatology category of the Journal Citation Reports database were selected. We analyzed the following measures for 2000–2009: (1) total number of articles originating from ML, HK, and TW; (2) impact factor (IF) of those articles; (3) total number of citations and average number of citations per article; and (4) number of articles about clinical trials, randomized controlled trials (RCT), and case reports. We also noted the total number of articles from the 3 regions published in 10 top-ranking journals.Results.There were 788 articles for the 3 regions of China, including 259 from ML, 372 from TW, and 157 from HK, with a positive trend between the years 2000 to 2009. From 2006 on, published articles from ML exceeded those from HK, and in 2008, published articles from ML exceeded those from TW. HK had the highest average IF and highest average citations of each article compared with articles from ML and TW. TW published the most RCT, clinical trials, and case reports, as well as the most articles in the 10 top-ranking journals in the last decade, followed by ML and HK.Conclusion.Chinese contributions to the field of rheumatology have increased rapidly since 2000, particularly from ML. HK had the highest quality research output according to average IF and average citations per article.
L'usage détermine-t-il le contexte chez Heidegger et chez Wittgenstein ?
Authors: Gauvry Charlotte 
Published: September 2010

Résumé On analyse les déterminations de la notion d’« usage » chez le premier Heidegger du début des années 1920 et chez le Wittgenstein des Recherches philosophiques . On distingue ainsi la notion d’usage de celle de « pratique de vie », plus précisément de celles d’« accomplissement » et de « forme » de vie pour montrer que, tout en étant très différents, usages heideggériens et usages wittgensteiniens sont des usages spécifiques, déterminés par les contextes qui leur résistent. On s’intéresse ainsi tout particulièrement à la notion d’« indication formelle » heideggérienne et au caractère thérapeutique, délibérément non herméneutique, du « contexte » des Recherches .
Qua. Heidegger, Wittgenstein et le nivellement logique du sens
Authors: Narboux Jean-Philippe 
Published: September 2010

Résumé On se propose de montrer que l’écart entre les critiques heideggérienne et wittgensteinienne de l’adoption du point de vue logique sur le sens et l’écart entre leurs conceptions respectives de la sensibilité du sens au contexte deviennent visibles et intelligibles à partir du moment où ils sont rapportés l’un à l’autre. On cherchera la clé de ce double écart dans un désaccord fondamental des deux philosophes sur le sort qui peut et doit être fait à l’usage philosophique du petit mot « qua » (« x qua y »), usage qui semble aussi ancien que la métaphysique elle-même.
De la question métaphysique à la création culturelle : métamorphoses du néokantisme d'Ernst Cassirer
Authors: Faivre d’Arcier Éléonore 
Published: September 2010

Résumé Nous nous intéressons dans cet article à la façon dont Ernst Cassirer renforce et réinvestit la méthode critique de Kant en replaçant l’imagination productrice (qui devient imagination symbolique ) non seulement au cœur de la théorie de la connaissance – désormais étendue au cosmos de la culture –, mais aussi au cœur d’une métaphysique renouvelée. La valorisation de la spontanéité – inséparable de ses objectivations, les formes symboliques –, traduit et sert les enjeux corrélatifs de l’idéalisme critique de Cassirer : d’une part, son combat mené à travers les déductions transcendantales contre les métaphysiques dogmatiques marchandes d’illusions dualistes au sein du savoir, d’autre part, la recherche d’un sens d’ordre métaphysique-anthropologique inspirant l’alliance de la forme et de la liberté pour la totalité systématique de la culture.
Le désintéressement malveillant
Authors: Wolfelsperger Alain 
Published: September 2010

Résumé Jon Elster montre, dans sa critique des modèles économiques, que les individus sont souvent plus motivés par leurs émotions (les « passions ») ou une conception de la justice (la « raison ») que par leur intérêt personnel. Mais, bien que ce désintéressement puisse être soit bienveillant soit malveillant à l’égard des autres, l’auteur n’analyse que l’influence de l’altruisme. Je défends ici la thèse qu’il faudrait donner aussi plus d’importance aux mauvaises passions humaines telles que la méchanceté ou la haine pour rendre convenablement compte de nombreuses situations sociales intéressantes.
Preparation of Hematopoietic Stem and Progenitor Cells from the Human Placenta
Authors: Robin Catherine , Dzierzak Elaine 
Published: September 2010

AbstractThis unit describes a protocol to isolate hematopoietic progenitors and stem cells from human placentae isolated at different time points in development and at the full‐term gestational stage. The placenta is extensively washed to eliminate blood contamination on its surface and inside the villi (the vascular compartments of the placenta). The placenta is then mechanically minced into pieces, which are subsequently digested with an enzyme cocktail. After dissociation and filtration, placental cells are available for further phenotypic and functional analyses. Curr. Protoc. Stem Cell Biol. 14:2A.9.1‐2A.9.8. © 2010 by John Wiley & Sons, Inc.
