Published: October 2012

ABSTRACTThe LaFeO3 and CaFeOX layers are grown using highly dense target prepared by Pechini method, with which accurate growth rate is achieved. Since the LaFeO3demonstrates the obvious RHEED oscillation until the end of growth, constant growth rate, and the step-terraces structure, the LFO is employed as a buffer and/or reference layer to determine the required pulses to deposit the thickness we desire in the superlattice. Superlattices show the clear satellite peaks and Laue oscillation in the XRD spectra as well as the oscillations caused by the film thickness with a flat surface and superstructure with a flat interface in the x-ray reflection spectrum. The streaky RHEED patterns and step-terraces surface are consistent with the results of spectra using x-ray.
Accompagnement de la fin de vie aux urgences
Authors: Grange Claude , Revue Eric , Héron Anne 
Published: October 2012

Résumé Un grand nombre de personnes en fin de vie décèdent aux urgences dans des conditions insatisfaisantes, sur des brancards, dans les couloirs, sans accompagnement adapté. Dans le cadre de la présente étude, un protocole spécifique d’accompagnement des patients admis aux urgences avec un diagnostic « soins palliatifs » a été élaboré, mis en place et testé sur une période de douze mois. La nature et la qualité de la prise en charge ont été évaluées par des questionnaires anonymes destinés aux personnels soignants référents, à l’équipe mobile de soins palliatifs et aux familles.
Dispersion des prix et efficacité des marchés compétitifs
Authors: Foucart Renaud 
Published: October 2012

Résumé En théorie, quand les marchés sont compétitifs, des biens identiques sont vendus à un prix unique. En pratique, cette loi ne se vérifie pas. Cet article s’attache à comprendre comment un marché disposant des caractéristiques proches de la concurrence parfaite peut présenter une dispersion des prix. C’est le cas lorsqu’il existe un coût infime de recherche de l’information et une possibilité pour les vendeurs de diversifier leurs espaces de vente, à qualité identique. En présence d’une telle dispersion des prix, le marché est inefficace à apparier vendeurs et acheteurs : une part des acheteurs consomme dans un magasin ne correspondant pas à ses préférences. Quand la consommation résulte d’une décision de groupe, comme c’est le cas pour de nombreux biens de loisirs, une deuxième défaillance de marché s’ajoute : une trop grande diversité de l’offre diminue la possibilité pour les groupes hétérogènes de disposer d’un appariement.
Le collège unique est-il (vraiment) un maillon faible ?
Authors: Zaffran Joël 
Published: October 2012

Résumé Le collège unique fait l’objet de critiques par ses détracteurs qui voient dans la démocratisation scolaire les causes de sa faiblesse. Cet article prend part au débat en discutant l’hypothèse selon laquelle le titre de « maillon faible » dont il est affublé ne certifie pas un allègement des contraintes que le collège impose aux adolescents mais une pression plus forte exercée par la forme scolaire. On assiste en effet au renforcement de la forme scolaire dû à trois dimensions inhérentes à la modernité avancée : le risque scolaire, la réflexivité, la dissociation du temps et de l’espace scolaires. De sorte que le mode scolaire de socialisation reste dominant dans les sphères d’activités sociales des adolescents dans et hors temps scolaire. Ce faisant, le titre de « maillon faible » est à rattacher aux conséquences de la modernité sur l’école et l’expérience adolescente.

Intraocular Lens Position Following In-the-Bag Implantation of Single-Piece Versus Three-Piece Acrylic Intraocular Lenses
Authors: Robert Marie-Claude , Harasymowycz Paul 
Published: October 2012

BACKGROUND AND OBJECTIVE:
To report the position of the single-piece and three-piece intraocular lenses (IOLs) following in-the-bag implantation.

PATIENTS AND METHODS:
Forty patients with bilateral age-related cataracts were recruited from both tertiary hospital and private practice in Montréal, Canada. Patients received the single-piece IOL in one eye and the three-piece IOL contralaterally. Postoperative anterior chamber depth (ACD) and iris-to-IOL distance were evaluated using a Scheimpflug imaging system.

RESULTS:

Mean ACD was 4.21 ± 0.32 mm for the single-piece IOL and 3.94 ± 0.34 mm for the three-piece IOL. Mean iris-to-IOL distance was 0.70 ± 0.19 mm for the single-piece IOL and 0.44 ± 0.21 mm for the three-piece IOL. The difference between paired eyes was 0.26 ± 0.20 mm (
P
= .002) for ACD and 0.25 ± 0.21 mm (
P <
.001) for iris-to-IOL distance.

CONCLUSION:
The single-piece IOL was positioned more posteriorly to the iris and allowed for a greater ACD than the three-piece IOL.
Le Caire, 2011. Plongée ethnographique au coeur des lijân sha’abeya (comités populaires)
Authors: Lachenal Perrine 
Published: October 2012

La place Tahrir, dans le centre-ville du Caire, apparaît comme la scène incontournable des mobilisations qui ont secoué l’Egypte au début de l’année 2011 et acculé Hosni Mubarak à quitter le pouvoir. On en oublierait presque le reste de la ville, immense, qui a été traversé durant cette même période, par des dynamiques qui ont donné naissance à des phénomènes inédits, dont les « comités populaires » font partie. Pour faire face au retrait calculé des forces de police et à la peur provoquée par les récits réels ou fantasmés – de violences urbaines, les habitants et habitantes du Caire s’organisent. D’abord de manière spontanée, puis de plus en plus « professionnelle », des centaines de « comités populaires », ou lijân sha’abeya, vont pendant plus de trois semaines, assurer la sécurité dans les différents quartiers du Caire. Ces « brigades » civiles, grâce à une étude réalisée à partir des discours de ceux et celles qui les ont incarnées, se révèlent être des exemples uniques d’organisation collective spontanée, supports d’alliances improbables et d’affirmations identitaires – spatiales et sexuées. Loin de l’épicentre de la révolution, dans l’espace familier des quartiers et l’intime des maisons, sur des scènes moins médiatisées, d’autres acteurs et actrices ont contribué à « faire » l’Histoire.

Published: October 2012

Cet article s’intéresse aux conséquences du « Printemps arabe » dans la seule monarchie du Maghreb. Moins fulgurant que dans d’autres pays, ce « printemps » n’en a pas moins favorisé une réforme constitutionnelle et des élections anticipées. C’est à travers le prisme du « Mouvement du 20 février », plateforme militante ayant réussi à mobiliser plusieurs dizaines de milliers de personnes à travers le Maroc durant le premier semestre 2011 que nous appréhendons les effets concrets de ce « Printemps arabe » in situ et les discours de ses acteurs marocains.
Vertebrobasilar dolichoectasia presenting as symptomatic obstructive hydrocephalus: A case report with review of literature
Authors: Seshadri Roopa , Sadashiva Nishant , Shukla Dhaval , Saini Jitender , Pandey Paritosh 
Published: October 2012

Abstract
Vertebrobasilar dolichoectasia (VBD) is a common, but usually asymptomatic condition characterized by marked elongation, dilatation, and tortousity of the vertebral and basilar arteries. VBD can sometimes present with symptoms related to mass effect like cranial nerve palsies, or with ischemia or hemorrhage. Hydrocephalus is an extremely uncommon presentation of VBD. We describe here a patient with VBD who presented with symptomatic hydrocephalus due to third ventricular obstruction, which was relieved by ventriculoperitoneal shunt.

Tensile Properties of Thermoplastic‐Laminated Composites Based on a Polypropylene Matrix Reinforced with Continuous Twaron Fibers
Authors: Mena‐Tun J. L. , Gonzalez‐Chi P. I. , Díaz‐díaz A. 
Published: October 2012

AbstractThe present paper focuses on a semiempirical macroscopic approach for the prediction of the tensile properties (modulus and strength) of thermoplastic laminates based on polypropylene (PP) reinforced with Twaron fibers. The influence of fiber content on the orthotropic stiffnesses and strengths of the unidirectional composite was experimentally determined; then, these orthotropic properties were the input data for the prediction, by means of the classical lamination theory, of the tensile effective properties of several PP/Twaron laminates. Good agreement was found between the predicted and experimental tensile data of the laminates. A previous publication focused on the modeling of the nonlinear behavior of PP/Twaron laminates; consequently, the results from the present work proved that the whole mechanical response of thermoplastic laminates PP/Twaron can be simulated by means of macroscopic models originally developed for thermosetting composites. © 2012 Wiley Periodicals, Inc.

Contribution of a 300 kHz alternating magnetic field on magnetic hyperthermia treatment of HepG2 cells

Published: October 2012

AbstractWe investigated the relative contributions of temperature and a 300 kHz alternating magnetic field (AMF) on magnetic hyperthermia treatment (MHT). Our system consisted of an induction coil, which generated AMF by electric current flow, and a newly developed, temperature‐controlled circulating water‐jacketed glass bottle placed inside the coil. The AMF generator operated at a frequency of 300 kHz with variable field strength ranging from 0 to 11 mT. Four treatment conditions were employed: (A) control (37 °C, 0 mT), (B) AMF exposure (37 °C, 11 mT), (C) hyperthermia (46 °C, 0 mT), and (D) hyperthermia plus AMF exposure (46 °C, 11 mT) for 30 min. Cell viability and apoptotic death rate were estimated. The relative contributions or interactions of hyperthermia (46 °C) and AMF (11 mT) on MHT were evaluated using 2 × 2 factorial experiment analysis. Group A was statistically different (P < 0.05) from each of the other treatments. The observed effects on both cell viability and apoptotic cell death were influenced by temperature (97.36% and 92.15%, respectively), AMF (1.78% and 4.99%, respectively), and the interactions between temperature and AMF (0.25% and 2.36%, respectively). Thus, the effect of hyperthermia was significant. Also, AMF exposure itself might play a role in MHT, although these observations were made in vitro. These findings suggest a possible presence of an AMF effect during clinical magnetic hyperthermia. Bioelectromagnetics 34:95–103, 2013. © 2012 Wiley Periodicals, Inc.
Study of photophysical properties of different metal complexes of Alq3
Authors: Bhagat S. A. , Raut S. B. , Dhoble S. J. 
Published: October 2012

ABSTRACTDifferent metal complexes of Alq3 (K+, Sr2+, Ca2+ and Mg2+) were synthesized by the precipitation method. The characterization of photoluminescence showed that presence of Mg2+ ion enhances photoluminescence of Alq3 phosphor. The emission spectra are observed at 560 nm when excited at a wavelength of 440 nm. The phosphor is excited at a longer wavelength in the blue region of small energy, so that it could be used as lamp phosphor. It is observed that the prepared phosphor AlMgq5 is more suitable than Alq3. The ionic radii of K+, Sr2+, Ca2+ and Mg2+ ions are in decreasing order. Therefore, the remarkable properties of AlMgq5 could be considered as promising materials as opto‐ or optoelectronic materials. Copyright © 2012 John Wiley & Sons, Ltd.

Published: October 2012

AbstractThe intramolecular and intermolecular vibrational energy flow in a polyproline peptide with a total number of nine amino acids in the solvent dimethyl sulfoxide is investigated using time‐resolved infrared (IR) spectroscopy. Azobenzene covalently bound to a proline sequence containing nitrophenylalanine as a local sensor for vibrational excess energy serves as a heat source. Information on through‐space distances in the polyproline peptides is obtained by independent Förster resonance energy transfer measurements. Photoexcitation of the azobenzene and subsequent internal conversion yield strong vibrational excitation of the molecule acting as a local heat source. The relaxation of excess heat, its transfer along the peptide and to the solvent is monitored by the response of the nitro‐group in nitrophenylalanine acting as internal thermometer. After optical excitation, vibrational excess energy is observed via changes in the IR absorption spectra of the peptide. The nitrophenylalanine bands reveal that the vibrational excess energy flows in the peptide over distances of more than 20 Å and arrives delayed by up to 7 ps at the outer positions of the peptide. The vibrational excess energy is transferred to the surrounding solvent on a time scale of 10–20 ps. The experimental observations are analyzed by different heat conduction models. Isotropic heat conduction in three dimensions away from the azobenzene heat source is not able to describe the observations. One‐dimensional heat dissipation along the polyproline peptide combined with a slower transversal heat transfer to the solvent surrounding well reproduces the observations. © 2012 Wiley Periodicals, Inc.

Published: October 2012

AbstractMobile communications have become one of the key points in the development of Information Society. Therefore the market demands to qualify engineers with a good formation on this topic, and more specifically related with good knowledge about the design and deployment of mobile and wireless networks and services of different technologies. For this reason most of the graduate and post‐graduate programs in Electrical and Electronic engineering studies consider at least one specific subject focused on mobile communications. However, the large number of concepts and the different existing technologies could make this subject very difficult for the student. This article presents a software tool for the design of second and third generation radio access networks, which makes easier the understanding and application of theoretical concepts, giving the student a more practical and realistic view of the subject. Furthermore as this tool has been applied for the regulation on mobile communications in different countries, the students can get some practical knowledge about the work in mobile communications in real world applications. © 2012 Wiley Periodicals, Inc.
