AbstractBiological aerosols from air constitute a significant source of exposure to microorganisms in public places. Airborne microorganisms are involved in the development of certain respiratory symptoms, allergies, or infections among users and occupants. Various sampling instruments have commonly been used in aerobiology to collect bacteria and fungi suspended in the air. The objective of this study was to develop a reliable procedure for sampling in indoor public environments presenting different levels of occupancy, airborne bacteria and fungi to be subjected to molecular analysis (bacteria and fungi quantitative PCR, capillary electrophoresis single strand conformation polymorphism fingerprinting). Four different sampling devices were tested in situ in an office building (open‐plan type) and the sampling strategy chosen was tested in two museum contexts. In accordance with the drawbacks involved to our study (quantitative and qualitative aspects, cost, and overcrowding), cyclone device appeared to be most suitable. The results underline the effectiveness of this high‐volume aerosol sampling device for both qualitative and quantitative molecular analysis. Four in situ sampling collections were carried out in 1 day in the Louvre Museum to study quantitative and qualitative variations of airborne bacterial and fungal diversity. The quantitative results revealed a similar order of magnitude for the numbers of both bacteria and fungi. In the Louvre Museum, the samples yielded between 3.7 × 104 and 4.1 × 104 genome equivalent (GE) bacteria/m3 air and between 5.0 × 104 and 5.9 × 104 GE fungi/m3 air and in the Decorative Arts Museum between, 2.1 × 104 and 2.5 × 104 GE bacteria/m3 air and between 1.4 × 104 and 1.7 × 104 GE fungi/m3 air. The results also indicate that the dominant bacterial community displayed a stable structure over a short period of time whereas dominant eukaryotic airborne community appeared more variable.

Published: December 2012

AbstractOver the past 30 years the literature has burgeoned with in situ approaches for groundwater remediation. Of the methods currently available, the use of metallic iron (Fe0) in permeable reactive barrier (PRB) systems is one of the most commonly applied. Despite such interest, an increasing amount of experimental and field observations have reported inconsistent Fe0 barrier operation compared to contemporary theory. In the current work, a critical review of the physical chemistry of aqueous Fe0 corrosion in porous media is presented. Subsequent implications for the design of Fe0 filtration systems are modeled. The results suggest that: (i) for the pH range of natural waters (>4.5), the high volumetric expansion of Fe0 during oxidation and precipitation dictates that Fe0 should be mixed with a non‐expansive material; (ii) naturally occurring solute precipitates have a negligible impact on permeability loss compared to Fe0 expansive corrosion; and (iii) the proliferation of H2 metabolizing bacteria may contribute to alleviate permeability loss. As a consequence, it is suggested that more emphasis must be placed on future work with regard to considering the Fe0 PRB system as a physical (size‐exclusion) water filter device.

Published: December 2012

AbstractBACKGROUND:Over the past several decades, the incidence of esophageal adenocarcinoma (EAC) has rapidly increased. The purpose of this analysis was to examine temporal trends in EAC incidence and mortality within the US population and, in addition, to explore these trends within subgroups of the population.METHODS:The National Cancer Institute (NCI) Surveillance, Epidemiology and End Results (SEER 9) data were used to examine incidence and incidence‐based (IB) mortality in EAC from 1975 to 2009. Secular trends in incidence and IB mortality by cancer stage, sex, and race were further characterized using the NCI's Joinpoint Regression program.RESULTS:Based on SEER 9 data, EAC incidence and IB mortality continues to increase in the United States. However, since the mid‐1990s, the overall rate of increase in both EAC incidence and IB mortality appears to be slowing. In addition, in early‐stage cancers, there is a noticeable leveling off of IB mortality rates and divergence from incidence starting in the late 1990s. Over the study period, the average annual percentage increase in incidence was 6.1% in men and 5.9% in women.CONCLUSIONS:EAC incidence and IB mortality rates continue to rise in the United States, although at a slower rate in more recent years. In early‐stage cancers, IB mortality and incidence rates have diverged primarily because IB mortality rates have plateaued beginning in the late 1990s. Although EAC continues to be less common in women, the rate of increase in EAC incidence is similar in both sexes. Cancer 2013. © 2012 American Cancer Society.
Quantitative analysis of axon bouton distribution of subthalamic nucleus neurons in the rat by single neuron visualization with a viral vector

Published: December 2012

AbstractThe subthalamic nucleus (STN) of the basal ganglia plays a key role in motor control, and STN efferents are known to mainly target the external segment of the globus pallidus (GPe), entopeduncular nucleus (Ep), and substantia nigra (SN) with some axon collaterals to the other regions. However, it remains to be clarified how each STN neuron projects axon fibers and collaterals to those target nuclei of the STN. Here we visualized the whole axonal arborization of single STN neurons in the rat brain by using a viral vector expressing membrane‐targeted green fluorescent protein, and examined the distribution of axon boutons in those target nuclei. The vast majority (8–9) of 10 reconstructed STN neurons projected to the GPe, SN, caudate‐putamen (CPu), and Ep, which received, on average ± SD, 457 ± 425, 400 ± 347, 126 ± 143, and 106 ± 100 axon boutons per STN neuron, respectively. Furthermore, the density of axon boutons in the GPe was highest among these nuclei. Although these target nuclei were divided into calbindin‐rich and ‐poor portions, STN projection showed no exclusive preference for those portions. Since STN neurons mainly projected not only to the GPe, SN, and Ep but also to the CPu, the subthalamostriatal projection might serve as a positive feedback path for the striato‐GPe‐subthalamic disinhibitory pathway, or work as another route of cortical inputs to the striatum through the corticosubthalamostriatal disynaptic excitatory pathway.

Skewness‐aware clustering tree for unevenly distributed spatial sensor nodes in smart city

Published: December 2012

SUMMARYEfficient spatial index is essential for querying spatial sensor nodes in the context of smart city. Sensor nodes are usually unevenly distributed in real situations. In this setting, R‐tree and its variants may cause large overlap and coverage among branch nodes, which impact the query efficiency greatly. To address this challenge, this paper proposes a novel skewness‐aware clustering tree (SWC‐tree) by clustering sensor nodes. Sensor nodes in a dense region will be put into the same node. Thus, overlap and coverage among node regions are less than that of R‐tree and its variants. As dense regions contain more sensor nodes, we assign a higher priority to these region nodes for facilitating the query operation. Experimental results show that in the context of skewed distribution, SWC‐tree is efficient in performance for conducting insertion, deletion, and query operations of sensor nodes.

Published: December 2012

AbstractWe report on the spin state photoswitching dynamics triggered by a femtosecond laser of [(TPA)FeIII(TCC)]+ cations in a new salt with SbF6– anions. Femtosecond optical pump‐probe spectroscopy and picosecond X‐ray diffraction techniques were combined to investigate the different steps of the out‐of‐equilibrium dynamics. The obtained results are very consistent with the ones previously reported for the PF6– salts. If the ultra‐fast responses of the cations in both salts are similar, the spin conversion due to laser heating is slightly shifted to higher temperature in the SbF6– salt, as its thermal crossover occurs at higher temperature.

Abstract
Contaminants used at low elevation, such as pesticides on crops, can be transported tens of kilometers and deposited in adjacent mountains in many parts of the world. Atmospherically deposited organic contaminants in the Sierra Nevada Mountains of California, USA, have exceeded some thresholds of concern, but the spatial and temporal distributions of contaminants in the mountains are not well known. The authors sampled shallow-water sediment and tadpoles (Pseudacris sierra) for pesticides, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls in four high-elevation sites in Yosemite National Park in the central Sierra Nevada twice during the summers of 2006, 2007, and 2008. Both historic- and current-use pesticides showed a striking pattern of lower concentrations in both sediment and tadpoles in Yosemite than was observed previously in Sequoia–Kings Canyon National Parks in the southern Sierra Nevada. By contrast, PAH concentrations in sediment were generally greater in Yosemite than in Sequoia–Kings Canyon. The authors suggest that pesticide concentrations tend to be greater in Sequoia–Kings Canyon because of a longer air flow path over agricultural lands for this park along with greater pesticide use near this park. Concentrations for DDT-related compounds in some sediment samples exceeded guidelines or critical thresholds in both parks. A general pattern of difference between Yosemite and Sequoia–Kings Canyon was not evident for total tadpole cholinesterase activity, an indicator of harmful exposure to organophosphorus and carbamate pesticides. Variability of chemical concentrations among sites, between sampling periods within each year, and among years, contributed significantly to total variation, although the relative contributions differed between sediment and tadpoles.

Decolonizing evaluation: The necessity of evaluation advisory groups in indigenous evaluation
Authors: Johnston‐Goodstar Katie 
Published: December 2012

AbstractResearch was and is central to the colonization and contemporary political realities of Indigenous communities. Because evaluation is a form of research and evaluation researchers are not immune to these oppressive practices, it is essential that evaluators acknowledge and engage with this history. One way to do this is through the use of advisory groups in evaluation research. This chapter will explicate how evaluation advisory groups can help evaluation practi‐tioners decolonize their practice. Decolonized evaluation is centered in Indigenous values and goals. It ensures that evaluation processes and outcomes are appropriate to native communities by centering Indigenous worldviews, actively including Indigenous participation, and focusing on relevance as defined by Indigenous communities. ©Wiley Periodicals, Inc., and the American Evaluation Association.

AbstractBreast cancer is a heterogeneous and complex disease. Although the use of tumor biomarkers has improved individualized breast cancer care, i.e., assessment of risk, diagnosis, prognosis, and prediction of treatment outcome, new markers are required to further improve patient clinical management. In the present study, a search for novel breast cancer‐associated genes was performed by mining the UniGene database for expressed sequence tags (ESTs) originating from human normal breast, breast cancer tissue, or breast cancer cell lines. Two hundred and twenty‐eight distinct breast‐associated UniGene Clusters (BUC1‐228) matched the search criteria. Four BUC ESTs (BUC6, BUC9, BUC10, and BUC11) were subsequently selected for extensive in silico database searches, and in vitro analyses through sequencing and RT‐PCR based assays on well‐characterized cell lines and tissues of normal and cancerous origin. BUC6, BUC9, BUC10, and BUC11 are clustered on 10p11.21‐12.1 and showed no homology to any known RNAs. Overall, expression of the four BUC transcripts was high in normal breast and testis tissue, and in some breast cancers; in contrast, BUC was low in other normal tissues, peripheral blood mononuclear cells (PBMCs), and other cancer cell lines. Results to‐date suggest that BUC11 and BUC9 translate to protein and BUC11 cytoplasmic and nuclear protein expression was detected in a large cohort of breast cancer samples using immunohistochemistry. This study demonstrates the discovery and expression analysis of a tissue‐restricted novel transcript set which is strongly expressed in breast tissue and their application as clinical cancer biomarkers clearly warrants further investigation. © 2012 Wiley Periodicals, Inc..
Experience in Scandinavia through the example of the Södermalm Tunnel / Erfahrungen in Skandinavien am Beispiel des Södermalmstunnels
Authors: Gamsjäger Hannes , Atzl Georg 
Published: December 2012

AbstractContract B‐9528 – Södermalm Tunnel is a good example of urban tunnelling, where tunnel alignments cannot be chosen freely due to existing buildings and subsurface structures. Around ten tunnel crossings and a number of difficult situations underpassing existing buildings were in the scope of Södermalm Tunnel with the main focus on the Maria Magdalena Church. A NATM approach enabled tunnelling of the first double track tunnel in Stockholm's Esker to succeed in very close vicinity of the church.Hauptbaulos B‐9528 – Södermalmstunnel ist ein Beispiel für innerstädtische Randbedingungen, wo die Linienführung des Tunnels von existierenden Bauwerken beeinflusst ist und nicht mehr frei wählbar ist. Neben rund zehn Tunnelkreuzungen war eine Reihe von schwierigen Gebäudeunterfahrungen im Auftragsumfang des Projekts B5‐9528 – Södermalmstunnel, wobei die Maria‐Magdalena‐Kirche im Fokus der Bemühungen stand. Ein NÖT‐Vortrieb ermöglichte im Nahbereich der Kirche die erste Durchörterung von Stockholms Esker (Oser) mit einem Großquerschnitt.
VIP – Tender Model for Infrastructure Projects / VIP – Vergabemodell für Infrastrukturprojekte
Authors: Eder Manfred 
Published: December 2012

AbstractIn connection with the many national and international attempts to improve “cooperation in construction”, a working group of the ITA Austria has been formed and has developed a new “Tender Model for Infrastructure Projects – VIP”. The mostly complete basic concept, which at the moment is being discussed and further developed together with representatives of employers, is the subject of this article.The VIP has the essential intention of moving away from the currently dominant “cheapest bidder principle” or “best bidder principle”, in which quality criteria play no role or are of only minor importance. The VIP lays more emphasis on qualitative award criteria and intends the award of the contract to the bidder whose bid has the highest “benefit to society”.Im Zusammenhang mit mehreren nationalen und internationalen Bestrebungen, die “Kooperation im Bauwesen” zu verbessern, hat sich eine Arbeitsgruppe der ITA Austria formiert und ein neues “Vergabemodell für Infrastrukturprojekte – VIP” entwickelt. Das weitgehend fertiggestellte Grundkonzept, welches zurzeit mit Vertretern von Auftraggebern abgestimmt und weiterentwickelt wird, ist Gegenstand dieses Beitrags.Das VIP verfolgt als wesentliches Ziel eine Abkehr vom derzeit dominanten “Billigstbieterprinzip” bzw. “Bestbieterprinzip”, bei dem qualitative Kriterien keine oder nur eine untergeordnete Rolle spielen. Das VIP legt ein höheres Gewicht auf qualitative Zuschlagskriterien und strebt an, den Auftrag jenem Bieter zu erteilen, dessen Angebot den höchsten “Nutzen für die Gesellschaft” hat.

Zur inneren Scherfestigkeit von Kunststoff‐Dränelementen
Authors: Müller Werner 
Published: December 2012

AbstractKunststoff‐Dränelemente werden auch in Böschungen eingebaut. Da sie in der Regel aus mehreren Komponenten, nämlich mindestens aus einem Dränkern und einem Filtervliesstoff bestehen, hängt die Standsicherheit u. a. von der inneren Scherfestigkeit der Produkte ab. Diese kann entweder durch die reine Reibung der Komponenten untereinander oder durch die mechanische Festigkeit von Fügestellen zwischen den Komponenten bedingt sein, die schon bei der Produktion hergestellt werden. Im letzteren Fall ist nicht klar, wie Ergebnisse von Reibungsversuchen im Rahmenschergerät zu interpretieren sind. Vor diesem Hintergrund wird gezeigt, wie die Druck‐ und Scherkräfte, die ein Produkt langfristig aushalten kann, aus einem Reibungsversuch im Zusammenhang mit Kriechversuchen abgeleitet werden können. Dieses Vorgehen wird bei der Zulassung nach der Deponieverordnung für den Einsatz in Deponieabdichtungen angewendet.On the internal shear strength of geocomposite drains. Geocomposite drains (GCD) are used on long and steep slopes. Since they are usually composed of different components, at least a drain core in connection with a nonwoven filter geotextile, the internal shear strength is of significant relevance for the slope stability. The internal shear strength may be due to pure friction forces between the different components or due to the mechanical strength of the bonding between the components achieved in a special production process. In the latter case the interpretation of the results of friction shear box tests is quite unclear. Against this background it is shown how the pressure and shear forces, which are acceptable for a product in the long run, may be derived from such a shear box test in combination with long‐term creep tests. The procedure is used within the framework of the certification of the products for landfill cover systems according to the German landfill ordinance.
Zur Steifigkeit bei kleinen Dehnungen im Rahmen der Hypoplastizität
Authors: Wegener Dirk , Herle Ivo 
Published: December 2012

AbstractWie Ergebnisse von Laborversuchen zeigen, ist einerseits die Steifigkeit bei kleinen Dehnungen deutlich höher und andererseits die Spannungsabhängigkeit weniger ausgeprägt als bei großen Dehnungen. Im vorliegenden Artikel wird gezeigt, wie man die Bodensteifigkeit im Bereich von sehr kleinen Dehnungen mit dem hypoplastischen Stoffgesetz mit intergranularen Dehnungen erfassen kann. Dazu werden die Gleichungen für die Berechnung der Steifigkeit bei kleinen und bei großen Dehnungen aufgestellt. Weiterhin wird erläutert, wie man die hypoplastischen Parameter zur Anwendung bei kleinen Dehnungen aus den bei großen Dehnungen bestimmten hypoplastischen Parametern berechnen kann. Dadurch ist es möglich, das Bodenverhalten infolge dynamischer Beanspruchung bis zu einer Scherdehnung von γ = 5·10–4 unter Berücksichtigung der spannungs‐ und dehnungsabhängigen Steifigkeit wirklichkeitsnah zu erfassen.Small strain stiffness in context of hypoplasticityIt can be observed in laboratory tests, that the soil stiffness at small strains is much higher and less stress‐dependent than at high strains. This paper demonstrates how the small‐strain stiffness can be calculated from the hypoplastic model with intergranular strains. Equations for the stiffness at small and large strains are presented. Subsequently it is explained how the hypoplastic parameters for the range of small strains can be calculated from the hypoplastic parameters determined at large strains. In this way it is possible to simulate realistically the soil behaviour due to dynamic loading up to a shear strain amplitude of γ = 5·10–4.
