Evolution of the Western Palaearctic Passerine Migration Pattern Presentation Style
Authors: Busse Przemysław , Zaniewicz Grzegorz , Cofta Tomasz 
Published: February 2015

Abstract
The scientific knowledge available in many detailed studies needs, from time to time, some generalization that allows to provide a synthesis or at least presentation of certain problem to both, scientific community and wide public interested in the topic. This article presents evolution of the presentation style of spatial course of the passerine migration in the Western Palaearcic. According to developing knowledge in the topic the style of presentation of general migration pattern evolved from a “line–arrow ” style suggesting that the birds use narrow “corridors” to more adequate to the phenomenon “carpet” style with called as “bottle-necks” concentrations being local and temporal effects of existing migratory barriers and guiding lines as maritime coasts, mountains and deserts. These details of migratory flyways are less visible in nocturnal passerine migrants than diurnal movements of both of passerines and gliding big birds. Generally, according to spatial relations between breeding and wintering areas of the bird populations living in Western Palaearctic four main flyways are defined and presented on maps: Western (Atlantic), Central (Apennine), South- Eastern (Balkan) and Eastern (Indian). Their background lies in the post-ice age history of distribution changes of the bird species, but details still evolve.

Authors: Awad Simon , Rząd Izabella 
Published: February 2015

Abstract
Work begun in autumn 2013 at a research ringing site near Jericho in the Jordan Valley (Palestine) was continued in spring 2014 (8 March–18 April). Due to a flood, the area was much changed in relation to the autumn habitat distribution. Standard ornithological and ringing work was performed using mist nets. The methods used were in accordance with SEEN (SE European Bird Migration Network) standards, and apart from ringing included some measurements (wing length, tail length, wing formula) and scores (fat determination and body mass), as well as testing of the directional preferences of migrants. The ornithological work was expanded to include parasitological testing, taking into account migrant-helminth relations during migration. Altogether 508 birds from 44 species were ringed and inspected for external signs of infection by Collyriclum faba trematodes (subcutaneous cysts), and an additional 32 dead individuals were collected and dissected. Altogether 168 internal parasites were found. The most common migrants in spring were Lesser Whitethroat Sylvia curruca, Blackcap Sylvia atricapilla and Olivaceous Warbler Hippolais pallida, while the autumn dominants–Masked and Red-backed shrikes (Lanius nubicus and L. collurio) were scarce. In spring a good number of Dead Sea Sparrows Passer moabiticus were caught, but only two introduced Indian Silverbills Lonchura malabarica.

ZusammenfassungZiel: In einer aktualisierten Umfrage des Arbeitsausschusses Positronenemissionstomographie (PET) der Deutschen Gesellschaft für Nuklearmedizin (DGN) sollten Informationen zum Einsatz der PET- und PET/CT-Diagnostik in Deutschland im Jahre 2013 ermittelt werden. Methoden: Die Daten wurden retrospektiv anhand eines gemeldeten Online-Fragebogens erfasst. Angaben zur Verfügbarkeit von Ärzten, Geräten und Radiopharmaka sowie zu Indikationen und Untersuchungszahlen wurden ausgewertet. Ebenso wurden Fragen zur Einordnung der PET und PET/CT in den diagnostischen Prozess untersucht. Zusätzlich wurde die in offiziell verfügbaren Krankenhausstatistiken dokumentierte Leistungserbringung analysiert. Ergebnisse: Ausgewertet wurde die Selbstauskunft von 52 Einrichtungen, welche rund 38 350 Untersuchungen in 2013 durchführten. Diese waren zu 87% der Onkologie zuzuordnen, auf Neurologie, Entzündungsdiagnostik und Kardiologie entfielen 7%, 5% bzw. 1%. Etwa 85% der Untersuchungen wurden durch Universitätskliniken und Krankenhäuser erbracht, 26% entfielen auf vollstationäre Fälle. Für die Bildgebung wurden meist Hybridgeräte genutzt (56 PET/ CT, 5 PET/MRT, nur 2 PET). Zu 90% wurden 18F-Radiopharmaka eingesetzt (68Ga 9%, 11C 1%). Als häufigste Tumorentitäten wurden Lungentumore (40%), maligne Lymphome (8%), gastrointestinale Tumore (5%) und NET (5%) genannt. Insgesamt waren 333 Ärzte im PET-Bereich tätig, davon 20% mit PET-Zertifikat. Reichlich 50% der Einrichtungen waren nach ISO9001, KTQ oder QEP zertifiziert. Fast 60% der onkologischen Untersuchungen wurden in einem interdisziplinären Tumorboard besprochen. Für den stationären Versorgungsbereich zeigte sich ein Zuwachs an PET-Leistungen von 56% innerhalb von 5 Jahren. Schlussfolgerung: Die PET-Diagnostik in Deutschland erfährt einen moderaten Zuwachs von ca. 9% pro Jahr, wird im internationalen Vergleich jedoch nach wie vor zurückhaltend eingesetzt.
An invasive plant alters phenotypic selection on the vegetative growth of a native congener
Authors: Beans Carolyn M. , Roach Deborah A. 
Published: February 2015

• Premise of the study: The ecological consequences of plant competition have frequently been tested, but the evolutionary outcomes of these interactions have gone largely unexplored. The study of species invasions can make an important contribution to this field of research by allowing us to watch ecological and evolutionary processes unfold as a novel species is integrated into a plant community. We explored the ecological and evolutionary impact of an invasive jewelweed, Impatiens glandulifera, on a closely related native congener, I. capensis and asked: (1) Does the presence of the invasive jewelweed alter the fitness of native jewelweed populations? (2) Does the invasive jewelweed affect the vegetative growth of the native congener? and (3) Does the invasive jewelweed alter phenotypic selection on the vegetative traits of the native congener?• Methods: We used a greenhouse competition experiment, an invasive species removal field experiment, and a survey of natural populations.• Key results: We show that when the invasive jewelweed is present, phenotypic selection favors native jewelweed individuals investing less in rapid upward growth and more in branching and fruiting potential through the production of nodes.• Conclusions: This research demonstrates that invasive plants have the potential to greatly alter natural selection on native competitors. Studies investigating altered selection in invaded communities can reveal the potential evolutionary impact of invasive competitors, while deepening our understanding of the more general role of competition in driving plant evolution and permitting species coexistence.
Villégiature et formation des banlieues résidentielles
Authors: Rabault-Mazières Isabelle 
Published: February 2015

Parti du constat de la coïncidence entre géographie de la villégiature au XIX e siècle et géographie actuelle de la banlieue résidentielle, l’article s’interroge sur le rôle joué par la villégiature bourgeoise dans la formation des banlieues résidentielles de Paris. Après avoir mis en évidence l’impact des maisons de campagne dans le parc immobilier mais aussi la fragilité de ces espaces résidentiels, l’étude de deux lotissements de villégiature et le suivi de leurs « usagers » dans les matrices mobilières permettent d’analyser concrètement le rôle contrasté joué par la villégiature dans le processus de peuplement.
Du projet utopique à la réalité
Authors: Villaret Sylvain 
Published: February 2015

C’est en 1931 que les docteurs G. et A. Durville entreprennent de fonder sur l’île du Levant la première commune naturiste de France : Héliopolis. Au-delà du symbole, il s’agit aussi d’offrir au plus grand nombre un lieu propice à la pratique du naturisme durant les vacances estivales. Dépassant le rêve d’une cité utopique, les frères Durville concrétisent pour partie leurs ambitions. En retraçant, la genèse et le premier essor d’Héliopolis, notre propos est de montrer que c’est en « jouant » la carte du tourisme et des loisirs qu’ils s’efforcent d’aménager de façon pérenne une cité qui non seulement satisfasse à l’idéologie naturiste, mais obtienne également la reconnaissance des autorités publiques. Reste que si l’objectif de fonder une micro-société naturiste se révèle rapidement un échec. Héliopolis s’affirme comme une cité de loisirs emblématique et annonce, in fine , l’avènement d’un naturisme de masse de plus en plus hédoniste.
« Le repaire et la bergerie des brebis du Seigneur au milieu de la France »
Authors: Foa Jérémie 
Published: February 2015

Parce qu’elle est à la fois la capitale du protestantisme (1562-1568) et le front pionnier de la reconquête catholique (1568-1572), Orléans expérimente successivement tous les cas de figure de la biconfessionalité urbaine : domination protestante (avril 1562-mars 1563 et septembre 1567-mars 1568) puis domination catholique (à partir de mars 1568) ; coexistence pacifique (mars 1563-septembre 1567), puis affrontements violents (1568-1572), qui culminent avec le massacre de la Saint-Barthélemy. Se joue à Orléans, en accéléré et avec une intensité inédite, ce qu’on observe dans le royaume de France sur le temps long des guerres de Religion : le passage de l’espoir d’une Réforme à la française à la dépossession huguenote. Cet article ambitionne d’interroger la défaite des réformés à travers les questions d’espace, en faisant du paysage urbain non simplement le cadre, mais bien un acteur décisif du conflit confessionnel et de la déprise protestante.
Entre confiture et photographie, notes sur la couleur subjonctive
Authors: Lecerf Guy 
Published: February 2015

Que se passe-t-il entre les actes de la confiture et ceux de la photographie ? De quel jeu s’agit-il ? Il se fait que j’imagine, j’invente mon quotidien et, à l’occasion, je parle de couleur. Ainsi dans la série Oasis, Miroirs Myrtilles (2010), je peux passer – là au bord d’un chaudron de confitures en ébullition – de la catastrophe dans sa banalité à la photographie. Ce passage peut se comprendre en termes de dépiction ou de proposition : la dépiction (Stephen Kosselyn, 2006) s’intéresse aux variations de colorations, à l’ambiguïté de l’image, à sa picturalité. A contrario , l’identification de la couleur impose la proposition et, en particulier, la dénomination. L’analyse propositionnelle ouvre sur une « grammaire » fondée sur des modes ; d’où la notion de « couleur subjonctive » (Hilary Putnam, 1983) qui envisage la couleur comme une potentialité, le fait qu’elle puisse avoir un avenir dans l’esprit de celui qui la voit et qui en parle. Cette notion permet de mieux saisir ce qui, par la modalité subjonctive de la proposition de couleur, me relie au monde commun et, chaque jour, me fait inventer et imaginer des mondes possibles et imprévisibles dans une sorte de balancement sans fin entre confiture et déconfiture.
Automobilités postmodernes : quand l'Autolib' fait sensation à Paris
Authors: Tremblay Jean-Pierre 
Published: February 2015

Le présent article vise à mettre au jour les soubassements imaginaires d’un objet socio-technique urbain contemporain : l’Autolib’. Sur la base d’une enquête de terrain approfondie, elle-même couplée à une phénoménologie herméneutique consistante, nous montrons que la petite voiture de location d’apparence anodine, mise en place à Paris en 2011, se révèle être un indicateur privilégié d’une dynamique macrosociale sous-jacente : soit le passage d’une épistémè « moderne » à une épistémè « postmoderne ». À travers l’examen de l’esthétique du véhicule (que l’on caractérise comme poly-identificatoire), comme de ses caractéristiques et fonctionnalités les plus saillantes (la voiture électrique connectée illustre le topos contemporain de « l’enracinement dynamique »), nous mettons au jour les diverses modalités socio-anthropologiques qui permettent d’envisager l’objet « Autolib’ » comme le produit/producteur, parmi d’autres choses, d’un nouveau « bassin sémantique ».

Published: February 2015

Purpose The pharmacokinetic properties of vancomycin (VAN) and teicoplanin (TEC) may be affected by adsorption during hemofiltration as well as hemoperfusion therapies. The aim of this in vitro study was to investigate VAN and TEC removal adsorption kinetics with mass balance analysis by direct hemoperfusion (DHP) with the Lixelle S-35 cartridge (Lixelle, Kaneka Corporation, Tokyo). Methods Mock DHP was performed for 120 min using VAN and TEC solutions (46.08 ± 0.81 and 74.79 ± 1.24 mg/l per N = 6). Clinical plasma antibiotic concentrations were circulated in a closed circuit simulating DHP using an adsorption column (Lixelle S-35) at flow rate of 250 ml/min. Samples were collected at 10, 60, and 120 min through both arterial and venous ports; drug levels were measured with particle enhanced turbidimetric inhibition immunoassay and fluorescence polarization immunoassay. All tests were performed in triplicate. Results: Results subsequent to DHP at the primary assessment interval for VAN mass was 49.06 ± 1.47 mg, indicating a significant reduction of the starting mass (94.74 ± 1.63 mg). The observed reduction of TEC levels greatly exceeded that of VAN at the first interval (10 min). At 120 min of DHP, the estimated mass adsorption of VAN was 45.68 ± 2.26 mg, while the mesured total TEC mass adsorbed was 126.86 ± 0.91 mg. Conclusions A VAN adsorption plateau indicating the VAN loading dose may be required in patients receiving DHP with the Lixelle S-35. The total TEC mass was adsorbed subsequent to 60 min of circulation, so the loading dose should be closely considered. In addition, the Lixelle S-35 may represent an option as a rescue therapy in accidental overdose of TEC.

Abstract

Human induced pluripotent stem cells (hiPSCs) hold great promise for cell therapy through their use as vital tools for regenerative and personalized medicine. However, the genomic integrity of hiPSCs still raises some concern and is one of the barriers limiting their use in clinical applications. Numerous articles have reported the occurrence of aneuploidies, copy number variations, or single point mutations in hiPSCs, and nonintegrative reprogramming strategies have been developed to minimize the impact of the reprogramming process on the hiPSC genome. Here, we report the characterization of an hiPSC line generated by daily transfections of modified messenger RNAs, displaying several genomic abnormalities. Karyotype analysis showed a complex genomic rearrangement, which remained stable during long-term culture. Fluorescent in situ hybridization analyses were performed on the hiPSC line showing that this karyotype is balanced. Interestingly, single-nucleotide polymorphism analysis revealed the presence of a large 1q region of uniparental disomy (UPD), demonstrating for the first time that UPD can occur in a noncompensatory context during nonintegrative reprogramming of normal fibroblasts.

AbstractDespite orders of magnitude difference in atmospheric reactivity and great diversity in biological functioning, little is known about monoterpene speciation in tropical forests. Here we report vertically resolved ambient air mixing ratios for 12 monoterpenes in a central Amazon rainforest including observations of the highly reactive cis‐β‐ocimene (160 ppt), trans‐β‐ocimene (79 ppt), and terpinolene (32 ppt) which accounted for an estimated 21% of total monoterpene composition yet 55% of the upper canopy monoterpene ozonolysis rate. All 12 monoterpenes showed a mixing ratio peak in the upper canopy, with three demonstrating subcanopy peaks in 7 of 11 profiles. Leaf level emissions of highly reactive monoterpenes accounted for up to 1.9% of photosynthesis confirming light‐dependent emissions across several Amazon tree genera. These results suggest that highly reactive monoterpenes play important antioxidant roles during photosynthesis in plants and serve as near‐canopy sources of secondary organic aerosol precursors through atmospheric photooxidation via ozonolysis.
Prediction of Glossosoma biomass spatial distribution in Valley Creek by field measurements and a three‐dimensional turbulent open‐channel flow model

AbstractThe fluid flow environment associated with high Glossosoma abundance is predicted by large‐eddy simulation of a natural turbulent open‐channel flow. The spatial distribution of Glossosoma was depicted by high resolution physical variables described by fluid flow and streambed topography. Variogram analysis of the streambed topography revealed a characteristic length scale of the streambed of the order 0.2 m over which bed roughness height was correlated. Flow simulation output was spatially and temporally averaged over the streambed characteristic length scale and linked to Glossosoma spatial density. A dimensionless scaling relationship between Glossosoma spatial distribution and streamwise velocity averaged in the longitudinal and transverse direction, spatial velocity fluctuation, and spanwise vorticity from the computational fluid dynamics simulation output explained 79% of the variation in observed dimensionless Glossosoma spatial density. The analysis demonstrated that computational fluid mechanics and high resolution bed topography could be instrumental in predicting benthic macroinvertebrate spatial distribution in streams and rivers.

AbstractWater dissociation is crucial in many catalytic reactions on oxide‐supported transition‐metal catalysts. Supported by experimental and density‐functional theory results, the effect of the support on OH bond cleavage activity is elucidated for nickel/ceria systems. Ambient‐pressure O 1s photoemission spectra at low Ni loadings on CeO2(111) reveal a substantially larger amount of OH groups as compared to the bare support. Computed activation energy barriers for water dissociation show an enhanced reactivity of Ni adatoms on CeO2(111) compared with pyramidal Ni4 particles with one Ni atom not in contact with the support, and extended Ni(111) surfaces. At the origin of this support effect is the ability of ceria to stabilize oxidized Ni2+ species by accommodating electrons in localized f‐states. The fast dissociation of water on Ni/CeO2 has a dramatic effect on the activity and stability of this system as a catalyst for the water‐gas shift and ethanol steam reforming reactions.

Published: February 2015

AbstractPdCo nanotube arrays (NTAs) supported on carbon fiber cloth (CFC) (PdCo NTAs/CFC) are presented as high‐performance flexible electrocatalysts for ethanol oxidation. The fabricated flexible PdCo NTAs/CFC exhibits significantly improved electrocatalytic activity and durability compared with Pd NTAs/CFC and commercial Pd/C catalysts. Most importantly, the PdCo NTAs/CFC shows excellent flexibility and the high electrocatalytic performance remains almost constant under the different distorted states, such as normal, bending, and twisting states. This work shows the first example of Pd‐based alloy NTAs supported on CFC as high‐performance flexible electrocatalysts for ethanol oxidation.

Published: February 2015

AbstractFrom scanning tunneling microscopy (STM) images of rationally designed helical polymers with a pattern of π–π stacking, we successfully identified the single‐ and double‐helical superstructures. The STM images of the helical structures revealed the smallest helical architecture (diameter ca. 1.3 nm) that has been seen so far. Furthermore, the interconversion of single and double helices was further underpinned by experimental analyses. Significantly, the formation of double helices induced different supramolecular chirality to that observed for the single helices.
