Evaluating the effectiveness of rolling impact compaction at a brownfield site with high and low frequency seismic surface waves and geotechnical testing
Authors: Whiteley Robert J. , Caffi Peter 
Published: October 2013

ABSTRACTUsing a case study from a brownfield site in Australia that contained substantial uncontrolled crushed rock fill, we demonstrate that innovative geophysics and ground improvement using rolling dynamic compaction can provide alternatives to costly excavation, removal and re‐engineering of soils. This approach can also overcome some of the limitations of conventional geotechnical testing in such conditions. The process we have developed involves selection and levelling of trial areas within larger brownfield sites. These are initially screened with electromagnetic geophysics to target environmental sampling sites, buried objects and local areas of potentially unsuitable or contaminated soils for removal and replacement. High and low frequency surface wave testing is then completed along closely spaced lines within the trial areas using specially adapted Multi‐channel Analysis of Surface Waves (MASW) methods and a modified land streamer. This provides S‐wave velocity distributions within fill and deeper materials over two depth ranges, at high vertical resolution from approximately 0 to 2 m and at lower resolution from 2 to ~10 m. These results are compared with geotechnical engineering test information. Ground improvement works are then undertaken using rolling dynamic compaction with a ‘square’ impact roller.Within this brownfield trial area, geotechnical testing showed that post‐compaction in‐situ densities increased by about 6 to 10%, while S‐wave velocities increased by up to 40%. This clearly demonstrates the sensitivity of S‐wave velocities to soil and fill modulus. The S‐wave velocity sections also showed the consistency of the landform created by impact rolling and that both high and low frequency MASW testing is needed for more accurate assessment of the densification of both shallow and deeper fill. Normalized S‐wave velocity difference sections and Cone Penetrometer Testing (CPT) provided a clear indication of the depth of influence of the impact rolling.A relationship was developed between post‐compaction S‐wave velocity and Dry Density Ratio (DDR) that formed the basis of a viable geotechnical verification strategy for the ground improvement works on the larger brownfield site. Electromagnetic and advanced surface wave geophysics, combined with innovative ground improvement methods by rolling dynamic compaction, represent an advance over current practice for brownfield site development.
Substrate-Induced Protein Stabilization Reveals a Predominant Contribution from Mature Proteins to Peptides Presented on MHC Class I

Published: October 2013

Abstract
The origin of the MHC class I–presented peptides are thought to be primarily from newly synthesized but defective proteins, termed defective ribosomal products. Most of the data supporting this concept come from studies in which inhibitors of protein synthesis were found to rapidly block Ag presentation even when cells contained a pool of mature proteins. However, these data only indirectly address the origin of presented peptides, and in most studies, the contribution of mature functional proteins to the class I peptide pool has not been directly quantified. In this report, we address the efficiency and contribution of mature proteins using a tetracycline-inducible system to express Ags that are conditionally stabilized upon ligand binding. This system circumvents the use of general inhibitors of protein synthesis to control Ag expression. Moreover, by controlling Ag stabilization, we could investigate whether the degradation of mature Ags contributed to Ag presentation at early and/or late time points. We show that mature proteins are the major contributor of peptides presented on class I for two distinct antigenic constructs. Furthermore, our data show that the protein synthesis inhibitors used previously to test the contribution of defective proteins actually block Ag presentation in ways that are independent from blocking Ag synthesis. These data suggest that for the constructs we have analyzed, mature functional proteins, rather than defective ribosomal products, are the predominant source of MHC class I–presented peptides.

Abstract
The complement system is an important part of the innate immune system. The complement cascade may be initiated downstream of the lectin activation pathway upon binding of mannan-binding lectin, ficolins, or collectin kidney 1 (CL-K1, alias CL-11) to suitable microbial patterns consisting of carbohydrates or acetylated molecules. During purification and characterization of native CL-K1 from plasma, we observed that collectin liver 1 (CL-L1) was copurified. Based on deglycosylation and nonreduced/reduced two-dimensional SDS-PAGE, we detected CL-K1 and CL-L1 in disulfide bridge-stabilized complexes. Heteromeric complex formation in plasma was further shown by ELISA and transient coexpression. Judging from the migration pattern on two-dimensional SDS-PAGE, the majority of plasma CL-K1 was found in complex with CL-L1. The ratio of this complex was in favor of CL-K1, suggesting that a heteromeric subunit is composed of one CL-L1 and two CL-K1 polypeptide chains. We found that the complex bound to mannan-binding lectin–associated serine proteases (MASPs) with affinities in the nM range in vitro and was associated with both MASP-1/-3 and MASP-2 in plasma. Upon binding to mannan or DNA in the presence of MASP-2, the CL-L1–CL-K1 complex mediated deposition of C4b. In favor of large oligomers, the activity of the complex was partly determined by the oligomeric size, which may be influenced by an alternatively spliced variant of CL-K1. The activity of the native heteromeric complexes was superior to that of recombinant CL-K1. We conclude that CL-K1 exists in circulation in the form of heteromeric complexes with CL-L1 that interact with MASPs and can mediate complement activation.

Published: October 2013

A partir de los años setenta, el estudio de la calidad de vida, desde una perspectiva biomédica, psicológica y social, comienza a hacerse más sistemático y relevante en el mundo académico. La calidad de vida se la hadefinido, principalmente desde un punto de vista subjetivo (OMS, 1995), destacando la percepción de las personas sobre diversos ámbitos de susvidas, donde lo importante es destacar la relevancia del contexto social y cultural y del sistema de valores en el que experimentan su vida cotidiana.
Le Zarathoustra de Nietzsche et Maître Eckhart1
Authors: Keiji Nishitani , Isaac Sylvain 
Published: October 2013

Les pensées de Nietzsche et de Maître Eckhart constituent deux influences majeures qui traversent toute l’oeuvre de Nishitani. Dans ce beau texte, rédigé lors de son séjour d’études (1937-1939) à l’université de Fribourg auprès de Heidegger, Nishitani fait une lecture tout à fait originale et innovante de la mystique eckhartienne, en la mettant en contraste avec la figure de Zarathoustra chez Nietzsche. Au-delà de leurs conditions historiques et de la spécificité de leurs démarches respectives, il leur reconnaît une attitude fondamentale commune qui consiste à approfondir ce qu’il nomme le « mouvement dialectique de la vie » (lequel vise une affirmation de l’homme à travers la négation de celui-ci) en direction du fond infondé qui soutient toute existence. Par « caractère originaire de la vie », il entend la source de la vie dans son absence de fondement et de limite, dans son absence de raison. Ce faisant, et bien que relativement précoce (1938), cet essai annonce quelques-unes des intuitions les plus fulgurantes de Nishitani et offre une première esquisse de la plupart des thématiques qui lui tiendront particulièrement à coeur dans ses travaux à venir. Aussi y est-il déjà question de la vacuité, du savoir du non-avoir par opposition à la distinction sujet-objet, de la problématique de la représentation attachée à son exigence d’objectivité, de la compréhension de l’au-delà comme immanent à ce monde-ci, etc. Même la thématique du nihilisme, qui n’est pourtant pas nommément mentionnée, y fait écho dans l’exemple significatif du sentiment que tout est égal, que tout se vaut. En raison de la forme encore largement germinale que prennent ici ces réflexions, il est plus aisé d’en percevoir la portée et les imbrications. D’une certaine manière, on pourrait considérer cet essai comme un prélude aux importants développements que connaîtra la pensée nishitanienne jusqu’à l’ouvrage de maturité, Qu’est-ce que la religion ? (『宗教とはなにか』) de 1961.
Mystique du néant et śūnyatā selon la perspective de l’École de Kyōto
Authors: Vianello Giancarlo 
Published: October 2013

Au début des années 1960, Ueda Shizuteru alla étudier à Marburg, sous la direction d’Ernst Benz. Le travail de cette époque se concentra sur la spéculation de Maître Eckhart et sur la comparaison avec le bouddhisme. En particulier, l’étude de Ueda fit émerger deux différentes approches de la question du néant. La mystique du néant et laśūnyatābouddhiste furent analysées dans leurs aspects constitutifs. Cet approfondissement se révèle précieux, non seulement comme étude interculturelle, mais surtout comme contribution à l’interprétation du contexte nihiliste que l’Europe et le Japon se retrouvent à partager et auquel ces derniers ont affaire. Les observations de Ueda et, en général, des auteurs de l’École de Kyōto, offrent une perspective totalement autre dans la façon de traiter les noeuds ontologiques et théologiques de la pensée occidentale.
Aiamie1, agir au mieux ? Éthique, rituels catholiques et corps social chez les Anicinabek depuis les années 1950
Authors: Bousquet Marie-Pierre 
Published: October 2013

Cet article analyse la performance de rituels catholiques communautaires, comprenant des processions et des bénédictions, chez les Anicinabek (Algonquins). Il avance que leur étude donne à voir, dans le temps, l’éthique anicinabe. En effet, la période retenue, entre les années 1950 et 2000, correspond à des changements sociaux qui ont bouleversé l’ordre sociocosmique anicinabe. En portant attention à leur déroulement, à ce qu’ils mettent en scène du corps social, des relations avec le clergé et avec le surnaturel, nous postulons que ces rituels révèlent tant les transformations de l’imaginaire social et cosmologique anicinabe qu’un système de pensée pragmatique permettant de prendre les décisions pour se comporter, être et agir au mieux. Enfin, dans le contexte actuel où le catholicisme est en nette régression, nous examinons les nouveaux rites collectifs pour constater que ceux qui promeuvent les « bonnes manières de faire » tiennent essentiellement du domaine politique, terrain où se négocie maintenant la moralité commune.
L’Évolution religieuse humaine
Authors: Vecoli Fabrizio 
Published: October 2013

Cet article présente et discute l’ouvrage de Robert N. BellahReligion in Human Evolution. Le but de cette contribution est de remettre dans le contexte de l’ensemble de son oeuvre l’essai du sociologue américain Bellah, et plus spécifiquement d’en relever les enjeux majeurs dans le cadre des sciences des religions. L’analyse se concentre sur les chapitres les plus denses du point de vue de la théorie générale, délaissant quelque peu ceux où l’auteur présente les différents systèmes religieux abordés. La discussion critique se concentre sur un certain nombre de problèmes soulevés par l’ouvrage : le rapport entre la religion et l’histoire, la question de l’évolutionnisme dans les sciences des religions, l’utilisation de la catégorie d’époque axiale.
Action et contemplation
Authors: Bouso Raquel 
Published: October 2013

En 1923, Rudolf Otto a rassemblé un certain nombre d’annexes à Das Heilige (1917) et, dans l’une de celles-ci, il rapprocha le bouddhisme zen et le mystique médiéval Maître Eckhart. Le point commun était que, tout comme la vie vit sans pourquoi, vit parce qu’elle vit, l’homme juste travaille pour travailler, et ainsi seulement il est véritablement libre. Quand, en 1965, Shizuteru Ueda publia sa thèse de doctorat sur Eckhart, il inclut une comparaison avec le zen reprenant ce thème. À la lumière de la dichotomie action-contemplation dans la tradition occidentale, nous examinons les similitudes et les différences que souligne Ueda entre Eckhart et le zen à cet égard et leur signification pour la pensée contemporaine. Dans les deux cas, la projection au-delà de Dieu se traduit par une nouvelle manière d’être et d’agir dans le monde : celui qui a expérimenté cette vacuité ne demande plus pourquoi, ne cherche plus et, pour cette raison, a trouvé.

AbstractThe daytime 150 km echoes, which are associated with the upper E region field‐aligned irregularities, have been observed around the equatorial electrojet region but never before at magnetic latitudes near the northern anomaly crest region. We present first results of daytime 150 km echo over Sanya, China, a station located far away from the dip equator in the Northern Hemisphere. A layer of weak radar echoes with spectral width less than 10 m s−1 was seen in the height range from 145 km at 12:15 LT to 152 km at 13:45 LT on 21 July 2010. The interesting aspect is that the rare observation of daytime 150 km echoes with the small Sanya VHF radar was preceded by the occurrence of an unusual intermediate layer, which is identified as abnormal traces at the upper E region in corresponding ionograms. The abnormal intermediate layer associated with possible gravity wave activity (that implicates the presence of upper E region density gradients) could make a significant contribution to the growth of irregularities responsible for the rarely detected daytime 150 km echoes over Sanya.

ObjectiveTo determine the extent to which knee extensor strength and power explain variance in knee adduction moment (KAM) peak and impulse in clinical knee osteoarthritis (OA).MethodsFifty‐three adults (mean ± SD age 61.6 ± 6.3 years, 11 men) with clinical knee OA participated. The KAM waveform was calculated from motion and force data and ensemble averaged from 5 walking trials. The KAM peak was normalized to body mass (Nm/kg). The mean KAM impulse reflected the mean total medial knee load during stride (Nm × seconds). For strength, the maximum knee extensor moment attained from maximal voluntary isometric contractions (MVIC) was normalized to body mass (Nm/kg). For power, the maximum knee extensor power during isotonic contractions, with the resistance set at 25% of MVIC, was normalized to body mass (W/kg). Covariates included age, sex, knee pain on the Knee Injury and Osteoarthritis Outcome Score, gait speed, and body mass index (BMI). Relationships of the KAM peak and impulse with strength and power were examined using sequential stepwise forward linear regressions.ResultsCovariates did not explain variance in the KAM peak. While extensor strength did not, peak knee extensor power explained 8% of the variance in the KAM peak (P = 0.02). Sex and BMI explained 24% of the variance in the KAM impulse (P < 0.05). Sex, BMI, and knee extensor power explained 31% of the variance in the KAM impulse (P = 0.02), with power contributing 7% (P < 0.05).ConclusionKnee extensor power was more important than isometric knee strength in understanding medial knee loads during gait.

ObjectiveTo compare educational and vocational outcomes among adults with childhood‐onset systemic lupus erythematosus (SLE) and adult‐onset SLE.MethodsWe used data derived from the 2002–2010 cycles of the Lupus Outcomes Study, a longitudinal cohort of 1,204 adult subjects with SLE. Subjects ages 18–60 years living in the US (n = 929) were included in the analysis and were classified as childhood‐onset SLE if age at diagnosis was <18 years (n = 115). Logistic regression was used to assess the unadjusted and adjusted effect of childhood‐onset SLE, sex, race/ethnicity, baseline age, urban or rural location, and US region on the likelihood of completing a bachelor's degree. Generalized estimating equations were used to assess the effect of childhood‐onset SLE, demographics, education, and disease‐related factors on the odds of employment, accounting for multiple observations over the study period.ResultsSubjects with childhood‐onset SLE were on average younger (mean ± SD 29 ± 10 years versus 44 ± 9 years), with longer disease duration (mean ± SD 15 ± 10 years versus 11 ± 8 years). Subjects with adult‐onset SLE and childhood‐onset SLE subjects were equally likely to complete a bachelor's degree. However, subjects with childhood‐onset SLE were significantly less likely to be employed, independent of demographic and disease characteristics (odds ratio 0.62, 95% confidence interval 0.42–0.91).ConclusionWhile subjects with SLE are just as likely as those with adult‐onset SLE to complete college education, childhood‐onset SLE significantly increases the risk of not working in adulthood, even when controlling for disease and demographic factors. Exploring reasons for low rates of employment and providing vocational support may be important to maximize long‐term functional outcomes in patients with childhood‐onset SLE.

Published: October 2013

AbstractAsymmetric hydrogenation of ortho‐substituted pyridines catalyzed by N,P‐ligated iridium is demonstrated. To facilitate this reaction, the aromaticity of the pyridines was weakened by forming N‐iminopyridium ylides. The reactions give very high conversions, and after a single recrystallization, excellent ee of up to 98 % was obtained. This method lends itself to the synthesis of chiral piperidine building blocks.

AbstractCurauá fibers were used to reinforce elastomeric matrices with polyaniline (PAni) synthesized directly on the fiber surfaces to produce antistatic‐reinforced composites. In this work, composites of poly(ethylene‐co‐propylene‐co‐diene) with curauá fibers coated with PAni were prepared by mechanical mixing in a counter‐rotating twin rotor internal mixer. Then, mechanical and electrical properties of these composites were correlated to Raman and Fourier transformed infrared spectra (FTIR) using chemometric data analyze, such as principal component analysis (PCA) and hierarchical cluster analysis (HCA). Raman spectra showed correlation with electrical properties of conductive composites while FTIR spectra showed good correlation with mechanical properties. EPDM reinforced with PAni coated curauá fibers presented higher tensile strength and modulus than EPDM reinforced with pristine curauá fibers, indicating that the reinforcement effect was obtained. Chemical interaction between the phases occurs with formation of hydrogen bonding between the aminic nitrogens of PAni and the carbonyl groups of lignin of the fibers. © 2013 Wiley Periodicals, Inc.

Preparation, properties, and applications of acrylic–polyurethane hybrid emulsions in extinction electrophoresis

Published: October 2013

ABSTRACTAqueous acrylic–polyurethane hybrid emulsions (PUA) were fabricated by semibatch emulsion copolymerization using a mixture of acrylic (AC) monomers in the presence of an isocyanate terminated polyurethane (PU). The effects of PU content on the morphology of the hybrid emulsions and film properties were here investigated in detail using FT‐IR, UV, TEM, and SEM. TEM images clearly showed that hybrid emulsions exhibited a core‐shell structure before neutralization. However, after neutralization with N,N‐dimethylethanolamine, the typical particles exhibited phase inversion, producing particles with irregular hemispheres shapes and diameters about 0.5 μm. SEM images showed that the film surface became rougher as PU content increased, peaking at 10 wt %, the gloss of this film was 23.1 (60°). The UV transmittance spectra of the PUA hybrid emulsion within a wavelength range 700–200 nm decreased as PU content increased. This was consistent with the changes in the surface roughness of the film. Electrophoresis took place on an aluminum alloy surface and the product was dried at 120°C. The film exhibited excellent mechanical performance due to curing reaction between the NCO group on PU and hydroxyl group on the AC copolymer. The gloss of the film was found to be as low as 4.0 after electrophoresis testing. These films may be useful in practical extinction electrophoresis. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.
