D'où vient le présent des poèmes ? Digressions-transgressions 1909/2009
Authors: Roger Jérôme 
Published: June 2010

On part d’un constat : le temps dévolu à la lecture des poèmes en classe est le plus souvent un moment fétiche, amputé de la dimension historique de toute poésie. L’école feint alors d’aborder le poème comme un objet de culte, quels que soient d’ailleurs les présupposés de départ, sans plus se préoccuper de ce que Péguy appelait « son insertion éternellement temporelle ». Le cas du XX e siècle – un siècle plusieurs fois brisé – permet de reprendre à nouveaux frais cette question et de suggérer quelques réponses : le contemporain du poème n’est pas là où on l’attend et son présent est presque toujours intempestif.
Les décisions éthiques à la lumière du cadre conceptuel de Forsyth
Authors: Prat dit Hauret Christian 
Published: June 2010

Résumé L’objet de la recherche est de présenter le cadre conceptuel de Forsyth qui dresse une typologie des idéologiques éthiques. La taxinomie des idéologies éthiques a été construite en croisant deux dimensions : le relativisme et l’idéalisme. Le croisement de ces deux dimensions permet de faire émerger quatre idéologies différentes : le situationnisme, l’absolutisme, le subjectivisme et l’exceptionnisme.
Les élections européennes de juin 2009 en Bulgarie : la confirmation de l'éclatement du système partisan
Authors: Todorov Antony 
Published: June 2010

Résumé Le contexte des deuxièmes élections européennes de 2009 en Bulgarie est marqué par les développements politiques intervenus depuis 2001, date des élections législatives qui changèrent le paysage politique bulgare et mirent fin à la transition postcommuniste dans le pays. Ces élections entraînèrent un réalignement partisan significatif au sens de Stein Rokkan : l’engagement dans un processus de changement des alignements partisans des électeurs qui a conduit à l’éclatement du système antérieur de bipartisme 1 .
Diagnostic difficulties and pitfalls in rapid on-site evaluation of endobronchial ultrasound guided fine needle aspiration
Authors: Monaco* Sara E. , Schuchert Matthew J. , Khalbuss Walid E. 
Published: June 2010

Background:One of the novel techniques utilizing fine needle aspiration (FNA) in the diagnosis of mediastinal and lung lesions is the endobronchial ultrasound (EBUS)-guided FNA. In this study, we describe five cases which had a discrepancy between on-site evaluation and final diagnosis, or a diagnostic dilemma when rendering the preliminary diagnosis, in order to illustrate some of the diagnostic difficulties and pitfalls that can occur in EBUS FNA.Methods:A total of five EBUS FNA cases from five patients were identified in our records with a discrepancy between the rapid on-site evaluation (ROSE) and final diagnosis, or that addressed a diagnostic dilemma. All of the cases had histological confirmation or follow-up. The cytomorphology in the direct smears, cell block, and immunohistochemical stains were reviewed, along with the clinical history and other available information.Results:Two cases were identified with a nondefinitive diagnosis at ROSE that were later diagnosed as malignant (metastatic signet-ring cell adenocarcinoma and metastatic renal cell carcinoma (RCC)) on the final cytological diagnosis. Three additional cases were identified with a ROSE and final diagnosis of malignant (large cell neuroendocrine carcinoma (LCNEC) and two squamous cell carcinomas), but raised important diagnostic dilemmas. These cases highlight the importance of recognizing discohesive malignant cells and bland neoplasms on EBUS FNA, which may lead to a negative or a nondefinitive preliminary diagnosis. Neuroendocrine tumors can also be difficult due to the wide range of entities in the differential diagnosis, including benign lymphocytes, lymphomas, small and nonsmall cell carcinomas, and the lack of immunohistochemical stains at the time of ROSE. Finally, the background material in EBUS FNAs may be misleading and unrelated to the cells of interest.Conclusions:This study illustrates the cytomorphology of five EBUS FNA cases that address some of the diagnostic challenges witnessed while examining these specimens during ROSE. Many of the difficulties faced can be attributed to the baseline cellularity of the aspirates, the bronchial contamination, the difficulty identifying neoplasms with bland cytology, the wide spectrum of diseases that can occur in the mediastinum with overlapping cytomorphologic features, the mismatch between the background material and the cell populations present, and the overall unfamiliarity with these types of specimens.
Cell Adhesion and Cellular Patterning on a Self‐Assembled Monolayer of Zeolite L Crystals
Authors: Kehr Nermin Seda , Riehemann Kristina , El‐Gindi Jehad , Schäfer Andreas , Fuchs Harald , Galla Hans‐Joachim , De Cola Luisa 
Published: June 2010

AbstractChemically functionalized self‐assembled monolayers made by disk‐shaped zeolite L nanocrystals are used as models for biocompatible surfaces to study cell‐adhesion behavior. Different chemical groups lead to different cellular behavior and fluorescent‐molecule‐loaded zeolites allow the position of the cells to be determined. Furthermore, a patterned monolayer of asymmetrically functionalized zeolite L obtained by microcontact chemistry is used to grow cells. A spatial recognition of the cells, which proliferate only on the bioactive‐molecule‐functionalized stripes, is possible.
High‐Performance Air‐Stable n‐Type Organic Transistors Based on Core‐Chlorinated Naphthalene Tetracarboxylic Diimides

AbstractCore‐chlorinated naphthalene tetracarboxylic diimides (NDIs) with fluoroalkyl chains are synthesized and employed for n‐channel organic thin‐film transistors (OTFTs). Structural analyses of the single crystals and thin films are performed and their charge‐transport behavior is investigated in terms of structure–property relationships. NDIs with two chlorine substituents are shown to exhibit a herringbone structure with a very close π‐plane distance (3.3–3.4 Å), a large π‐stack overlap (slipping angle ca. 62°), and high crystal densities (2.046–2.091 g cm−3). These features result in excellent field‐effect mobilities of up to 1.43 cm2 V−1 s−1 with minimal hysteresis and high on–off ratios (ca. 107) in air. This is similar to the highest n‐channel mobilities in air reported so far. Despite the repulsive interactions of bulky Cl substituents, tetrachlorinated NDIs adopt a slip‐stacked face‐to‐face packing with an interplanar distance of around 3.4 Å, resulting in a high mobility (up to 0.44 cm2 V−1 s−1). The air‐stability of dichlorinated NDIs is superior to that of tetrachlorinated NDIs, despite of their higher LUMO levels. This is closely related to the denser packing of the fluorocarbon chains of dichlorinated NDIs, which serves as a kinetic barrier to the diffusion of ambient oxidants. Interestingly, these NDIs show an optimal performance either on bare SiO2 or on octadecyltrimethoxysilane (OTS)‐treated SiO2, depending on the carbon number of the fluoroalkyl chains. Their synthetic simplicity and processing versatility combined with their high performance make these semiconductors highly promising for practical applications in flexible electronics.
Nutrient transport within and between habitats through seed dispersal processes by woolly monkeys in north‐western Amazonia
Authors: Stevenson Pablo R. , Guzmán‐Caro Diana C. 
Published: June 2010

AbstractThe contribution of vertebrate animals to nutrient cycling has proven to be important in various ecosystems. However, the role of large bodied primates in nutrient transport in neotropical forests is not well documented. Here, we assess the role of a population of woolly monkeys (Lagothrix lagothricha lugens) as vectors of nutrient movement through seed dispersal. We estimated total seed biomass transported by the population within and between two habitats (terra firmeand flooded forests) at Tinigua Park, Colombia, and quantified potassium (K), phosphorus (P) and nitrogen (N) content in seeds of 20 plant species from both forests. Overall, the population transported an estimated minimum of 11.5 (±1.2 SD) g of potassium, 13.2 (±0.7) g of phosphorus and 34.3 (±0.1) g nitrogen, within 22.4 (±2.0) kg of seeds ha−1 y−1. Approximately 84% of all nutrients were deposited in theterra firmeforest mostly through recycling processes, and also through translocation from the flooded forest. This type of translocation represents an important and high‐quality route of transport since abiotic mechanisms do not usually move nutrients upwards, and since chemical tests show that seeds from flooded forests have comparatively higher nutrient contents. The overall contribution to nutrient movement by the population of woolly monkeys is significant because of the large amount of biomass transported, and the high phosphorus content of seeds. As a result, the phosphorus input generated by these monkeys is of the same order of magnitude as other abiotic mechanisms of nutrient transport such as atmospheric deposition and some weathering processes. Our results suggest that via seed dispersal processes, woolly monkey populations can contribute to nutrient movement in tropical forests, and may act as important nutrient input vectors interra firmeforests.

Application of an Enyne Metathesis/Diels–Alder Cycloaddition Sequence: A New Versatile Approach to the Syntheses of C‐Aryl Glycosides and Spiro‐C‐Aryl Glycosides
Authors: Subrahmanyam Ayyagari V. , Palanichamy Kalanidhi , Kaliappan Krishna P. 
Published: June 2010

AbstractAn efficient approach for the synthesis of a variety of C‐aryl and spiro‐C‐aryl glycosides is described. This diversity‐oriented strategy employed here relies on a sequential enyne metathesis to generate the 1,3‐diene moiety and Diels–Alder reaction with different dienophiles followed by aromatisation. Whereas cross‐enyne metathesis with ethylene gas is used to install the 1,3‐diene moiety at the anomeric centre for the synthesis of C‐aryl glycosides, an intramolecular enyne metathesis on the sugar enyne is performed to generate the 1,3‐diene moiety for the synthesis of spiro‐C‐aryl glycosides. Efforts to extend this strategy to the synthesis of the core structure of natural C‐aryl glycoside gilvocarcin are also described. A combination of both C‐aryl and spiro‐C‐aryl glycosides in the same moiety to combine the features thereof has also been accomplished. A tandem enyne metathesis/Diels–Alder reaction/aromatisation has also been attempted to directly access the C‐aryl glycosides in one pot albeit in low yield.
Metal–Organic Frameworks as Efficient Heterogeneous Catalysts for the Regioselective Ring Opening of Epoxides
Authors: Dhakshinamoorthy Amarajothi , Alvaro Mercedes , Garcia Hermenegildo 
Published: June 2010

AbstractAn iron‐based metal–organic framework, [Fe(BTC)] (BTC: 1,3,5‐benzenetricarboxylate) is an efficient catalyst in the ring opening of styrene oxide with alcohols and aniline under mild reaction conditions. Out of the various alcohols tested for ring opening of styrene oxide, methanol was found to be the most reactive in terms of percentage conversion and reactivity. The rate of the ring‐opening reaction of styrene oxide decreases as the size of the alcohol is increased, suggesting the location of active sites in micropores. [Fe(BTC)] was a truly heterogeneous catalyst and could be reused without loss of activity. The analogous compound [Cu3(BTC)2] was also found to be effective, although with somewhat lower activity than [Fe(BTC)]. The present heterogeneous protocol is compared with a homogeneous catalyst to give an insight into the reaction mechanism.
