Retour sur le statut juridique des assistants familiaux
Authors: Cherchari Mohammed Sahia 
Published: February 2011

Résumé La loi n° 2005-706 du 27 juin 2005 a assez profondément réformé la situation juridique des anciennes « assistantes maternelles permanentes », dénommées depuis lors « assistantes familiales » (ou assistants familiaux). Par-delà le changement terminologique, ce texte a clairement défini l’assistant familial, précisé que ce dernier est membre « à part entière » de l’équipe en charge de l’enfant accueilli et nettement distingué la profession des professions voisines. Par ailleurs, le nouveau statut a indiscutablement amélioré les conditions d’exercice du métier (formation, relations de travail, rémunération…). Pour autant, la loi du 27 juin 2005 et les textes qui sont venus la compléter n’ont pas tout réglé. D’abord parce que le statut des assistants familiaux reste un ensemble complexe, difficile, travaillé par des intérêts pas toujours convergents. Ensuite, parce qu’il y a, ici aussi, un temps entre normes, statut (im)posé et effectivité, mise en œuvre et en pratique des dispositions et dispositifs. Enfin, parce que le nouveau statut n’a toujours pas mis fin à la « précarité » relative ressentie par de nombreux assistants familiaux.
La technique au quotidien. Poétique de la modernité industrielle dans les Physiologies
Authors: Stiénon Valérie 
Published: February 2011

Les Physiologies parisiennes des années 1840 développent certaines considérations sur les progrès machiniques, notamment ceux qui concernent les moyens de transport. À travers leur poétique du quotidien de la monarchie de Juillet, quelles représentations de la civilisation technicienne les Physiologies construisent-elles ? Quelle place réservent-elles à la technique, parallèlement à leur mobilisation des paradigmes empruntés aux sciences du vivant ? Cette lecture transversale propose d’étudier comment les codes génériques de l’écriture de la Physiologie retraduisent, en une poétique spécifique, les valeurs modernes liées à la technique. Corrélativement, elle examine deux dystopies contre-technicistes sur lesquelles se focalise la dimension satirique de ces textes : les accidents de transports et les escroqueries financières.
Migration and Homeostasis of Naive T Cells Depends on Coronin 1-Mediated Prosurvival Signals and Not on Coronin 1-Dependent Filamentous Actin Modulation
Authors: Mueller Philipp , Liu Xiaolong , Pieters Jean 
Published: February 2011

Abstract
Coronins are WD repeat-containing proteins highly conserved in the eukaryotic kingdom implicated in the regulation of F-actin. Mammalian coronin 1, one of the most conserved isoforms expressed in leukocytes, regulates survival of T cells, which has been suggested to be due to its role in preventing F-actin–induced apoptosis. In this study, we come to a different conclusion. We show that coronin 1 does not modulate F-actin and that induction of F-actin failed to induce apoptosis. Instead, coronin 1 was required for providing prosurvival signals, in the absence of which T cells rapidly underwent apoptosis. These results argue against a role for coronin 1 in F-actin–mediated T cell apoptosis and establish coronin 1 as an essential regulator of the balance between prosurvival and proapoptotic signals in naive T cells.

Abstract
Binding of immunoglobulin protein (BiP) is a major molecular chaperone localized in endoplasmic reticulum (ER). It has been demonstrated to interact with nascent Ig. However, contrary to other ER-resident heat shock proteins such as gp96, calreticulin, and ORP150, it is not clear whether tumor-derived BiP plays a role in inducing antitumor immunity. In this study, we show that the tumor-derived secreted form of BiP is capable of inducing antitumor CD8+ T cell responses. We constructed an ER-retention signal KDEL-deleted mutant of BiP cDNA and transfected it to tumor cells, which resulted in continuous secretion of tumor-derived BiP into the extracellular milieu. We show that this secreted BiP is taken up by bone marrow-derived dendritic cells, and thereafter BiP-associated Ag peptide is cross-presented in association with MHC class I molecules, resulting in elicitation of an Ag-specific CD8+ T cell response and antitumor effect. This strategy to boost antitumor immune responses shows that a tumor could be its own cellular vaccine via gene modification of the secretion of the tumor Ag–BiP complex.
Observational Study to Assess the Therapeutic Value of Four Ovarian Hyperstimulation Protocols in IVF after Pituitary Suppression with GnRH Antagonists in Normally Responding Women

Published: February 2011

Objective To compare the clinical results of four different protocols of COH for IVF-ICSI in normovulatory women, using in all cases pituitary suppression with GnRH antagonists. Materials/methods A single center, open label, parallel-controlled, prospective, post-authorization study under the approved conditions for use where 305 normal responders women who were candidates to COH were assigned to r-FSH + hp-hMG (n = 51, Group I), hp-hMG (n = 61, Group II), fixed-dose r-FSH (n = 118, Group III), and r-FSH with potential dose adjustment (n = 75, Group IV) to subsequently undergo IVF-ICSI. Results During stimulation, Group IV needed significantly more days of stimulation as compared to Group II [8.09 ± 1.25 vs. 7.62 ± 1.17; P < 0.05], but was the group in which more oocytes were recovered [Group I: 9.43 ± 4.99 vs. Group II: 8.96 ± 4.82 vs. Group III: 8.78 ± 3.72 vs. Group IV: 11.62 ± 5.80; P < 0.05]. No significant differences were seen between the groups in terms of clinical and ongoing pregnancy, but among patients in whom two embryos with similar quality parameters (ASEBIR) were transferred, the group treated with hp-hMG alone achieved a significantly greater clinical pregnancy rate as compared to all other groups [Group I: 31.6%, Group II: 56.4%, Group III: 28.7%, Group IV: 32.7%; P < 0.05]. Conclusions Although randomized clinical trials should be conducted to achieve a more reliable conclusion, these observations support the concept that stimulation with hp-hMG could be beneficial in normal responders women undergoing pituitary suppression with GnRH antagonists.

AbstractWe present the results of a comprehensive study carried out on morphological, structural and optical properties of InAs/GaAs quantum dot structures grown by Molecular Beam Epitaxy. InAs quantum dots were deposited at low growth rate and high growth temperature and were capped with InGaAs upper confining layers. Owing to these particular design and growth parameters, quantum dot densities are in the order of 4‐5x109 cm‐2 with emission wavelengths ranging from 1.20 to 1.33 µm at 10 K, features that make these structures interesting for single‐photon operation at telecom wavelength. High resolution structural techniques show that In content and composition profiles in the structures depend on the particular epitaxial growth conditions used to reduce the density of quantum dots. Carrier recombination dynamics in quantum dots is studied by analysing the integrated photoluminescence (PL) intensity and recombination times as functions of the temperature. Arrhenius plots of the integrated PL show two activation energies implying two decay processes. The first one is associated to thermal escape of carriers from quantum dot to wetting layer states; the second one is consistent with the thermal population of quantum dot dark states, as suggested by time resolved PL measurements.

Application of circuit theory for extraction of water from oil
Authors: Midtgård Ole‐Morten 
Published: February 2011

SUMMARYThis paper discusses optimization of the performance of a pulsed dc electrostatic coalescer, a device that is used in the oil industry to increase the speed of separation of water from a water‐in‐oil emulsion. A previously found criterion for optimum performance, the charge hypothesis, is reviewed. Analysis by circuit theory shows that the performance may be improved through selecting an optimum switching frequency and duty ratio, improving the design of the pulse train generator, and making physical modifications to the coalescer apparatus. The addition of an external charging circuit is beneficial. Experiments on the modified system could contribute to a better understanding of the physics of the on period. The analyses further show that it is advantageous to have a thin layer of insulation, and that the insulation could be replaced by an external capacitor. The analytical circuit model gives important insight into the physical behavior of the system, which will be valid also for a geometry where the circuit parameters cannot be found analytically; charge separates in the on period, followed by a relaxation in the off period, and if the frequency or duty ratio is not relatively close to the optimum, the coalescer may not perform as expected.

Biomedicine in the environment: Cyclotides constitute potent natural toxins in plants and soil bacteria
Authors: Ovesen Rikke Gleerup , Brandt Kristian Koefoed , Göransson Ulf , Nielsen John , Hansen Hans Christian Bruun , Cedergreen Nina 
Published: February 2011

Abstract
Bioactive compounds produced by plants are easily transferred to soil and water and may cause adverse ecosystem effects. Cyclotides are gene-encoded, circular, cystine-rich mini-proteins produced in Violaceae and Rubiaceae in high amounts. Based on their biological activity and stability, cyclotides have promising pharmaceutical and agricultural applications. We report the toxicity of the cyclotides: kalata B1, kalata B2, and cycloviolacin O2 extracted from plants to green algae (Pseudokirchneriella subcapitata), duckweed (Lemna minor L.), lettuce (Lactuca sativa L.), and bacteria extracted from soil measured as [3H]leucine incorporation. Quantification by liquid chromatography-mass spectrometry demonstrated up to 98% loss of cyclotides from aqueous solutions because of sorption to test vials. Sorption was prevented by adding bovine serum albumin (BSA) to the aqueous media. Cyclotides were toxic to all test organisms with EC50 values of 12 through 140 µM (algae), 9 through 40 µM (duckweed), 4 through 54 µM (lettuce), and 7 through 26 µM (bacteria). Cycloviolacin O2 was the most potent cyclotide in all assays examined. This report is the first to document toxic effects of cyclotides in plants and soil bacteria and to demonstrate that cyclotides are as toxic as commonly used herbicides and biocides. Hence, cyclotides may adversely affect soil and aquatic environments, which needs to be taken into account in future risk assessment of cropping systems for production of these highly bioactive compounds.

Bioaccumulation kinetics of polybrominated diphenyl ethers from estuarine sediments to the marine polychaete, Nereis virens
Authors: Klosterhaus Susan L , Dreis Erin , Baker Joel E 
Published: February 2011

Abstract
Polybrominated diphenyl ethers (PBDEs) are flame-retardant chemicals that have become ubiquitous environmental contaminants. Polybrominated diphenyl ether no-uptake rates from estuarine or marine sediments to deposit-feeding organisms have not yet been reported. In the present study, the marine polychaete worm Nereis virens was exposed to field-contaminated and spiked sediments containing the penta- and deca-BDE commercial mixtures in a 28-d experiment to characterize the relative bioavailability of PBDE congeners from estuarine sediments. A time series sampling regimen was conducted to estimate uptake rate constants. In both field-collected and laboratory-spiked sediment exposures, worms selectively accumulated congeners in the penta-BDE mixture over BDE 209 and other components of the deca-BDE mixture, supporting the prevalence of these congeners in higher trophic level species. Brominated diphenyl ether 209 was not bioavailable to N. virens from field sediment and was only minimally detected in worms exposed to spiked sediments in which bioavailability was maximized. Chemical hydrophobicity was not a good predictor of bioavailability for congeners in the penta-BDE mixture. Direct comparison of bioavailability from the spiked and field sediments for the predominant congeners in the penta-BDE mixture was confounded by the considerable difference in exposure concentration between treatments. Biota-sediment accumulation factors (BSAFs) for N. virens after 28 d of exposure to the field sediment were lower than the BSAFs for Nereis succinea collected from the field site, indicating that 28-d bioaccumulation tests using N. virens may underestimate the in situ concentration of PBDEs in deposit-feeding species. The bioavailability of PBDEs to N. virens indicates that these chemicals can be remobilized from estuarine sediments and transferred to aquatic food webs. Environ. Toxicol.

Development of the osteocranium in Corydoras aeneus (Gill, 1858) Callichthyidae, Siluriformes
Authors: Huysentruyt Frank , Geerinckx Tom , Brunain Marleen , Adriaens Dominique 
Published: February 2011

AbstractDevelopment in the osteocranium of Corydoras aeneus was studied based on 48 cleared and stained specimens and 10 series of serial sections. Development overall follows the general trends observed in siluriform development, with ossifications appearing as a response to functional demands. Early development of the skull occurs in two distinct phases. In a first phase, several new bony elements, all of dermal origin and related to feeding, appear shortly after yolk depletion (4.4 mm SL). Between 5 and 8 mm SL, developmental priorities seem to shift to size increase of the cartilaginous skull and no new bony elements appear. Finally, a second phase of osteogenesis occurs from 8 to 18 mm SL, in which all remaining dermal and perichondral bones appear. J. Morphol. 2011. © 2011 Wiley‐Liss, Inc.

Authors: Wang Xiao‐Ming , Jiao Yong‐Chang , Weng Zi‐Bin , Zhang Fu‐Shun 
Published: February 2011

AbstractThis letter presents a detailed design procedure of leaky‐wave antenna (LWA) based on TE10 mode substrate integrated waveguide (SIW).The topology makes use of one of the fundamental characteristics of SIW, namely, its property of generating leakage loss when the period length is sufficiently large. The TE10 mode SIW is selected to design LWA for the first time in this letter because of its advantages of simple feed mechanism and convenient analytic approach. The design procedure is also presented in detail for the future design. The maximum radiation direction of the proposed antenna in the H‐plane scans from 124° to 109° (total 15°), while the frequency is operated from 10 to 11 GHz. A prototype is manufactured and measured to validate the simulation. All the results show that the proposed design serves as a suitable candidate for applications in millimeter‐wave road‐vehicle system or indoor wireless system. © 2011 Wiley Periodicals, Inc.

Design of frequency‐agile microstrip antennas with conical‐beam radiation
Authors: Tsai Jia‐Fu , Row Jeen‐Sheen 
Published: February 2011

AbstractA microstrip antenna with frequency agility is described in this article.The antenna has a circular radiating patch and operates at its TM01 mode to generate omnidirectional radiation across the azimuthal plane. To change the resonant frequency, a capacitor is introduced and connected to the antenna input port in series. With the increasing of capacitance, the resonant frequency is decreased while the resonant resistance and radiation characteristic nearly remain constant. Experimental results indicate that the design can provide a frequency tunable range of 22%; moreover, good impedance matching and stable radiation pattern are also obtained in the range. © 2011 Wiley Periodicals, Inc.

Published: February 2011

AbstractAn internal eight‐band LTE/WWAN on‐board printed antenna meeting the hearing air compatibility (HAC) specification of ANSI C63.19‐2007 in the bar‐type mobile phone is presented.The antenna is a coupled‐fed inverted‐F antenna directly printed on the system circuit board of the mobile phone and can generate two wide operating bands (698–960/1710–2690 MHz) to respectively cover the LTE700/ GSM850/900 and GSM1800/1900/UMTS/LTE2300/2500 operation. With the antenna disposed on the bottom edge of the circuit board and surrounded by an L‐shape ground plane, the near‐field strengths of the emitted electric and magnetic fields 15 mm above the acoustic output are evaluated to be in category M3 or M4 of the HAC specification. That is, the mobile phone with the embedded LTE/WWAN antenna can be treated as a hearing aid‐compatible wireless device. Details of the HAC results are presented. Effects of the user's hand holding the mobile phone on the near‐field emission of the antenna are also analyzed. © 2011 Wiley Periodicals, Inc.

Efficient analysis of waveguided structures using multiscalets‐finite element method based on new reduction meshing
Authors: Ali Adel Ben , Hajlaoui El Amjed , Gharsallah Ali 
Published: February 2011

AbstractHigh order multiscalets functions applied in a finite element method (MS‐FEM) using the tetrahedric elements is presented in this article. This method is based on a vector‐edge element, which is proposed for the global analysis of microstrip structures. However, this new computational technique will be presented when the electromagnetic differential equations are incorporated into interpolations. In first approach, multiscalets with higher order multiplicity r = 3 are employed as basis functions. A new mesh‐truncated technique is introduced for the frequency‐domain solution of closed‐region scattering problems. The main idea of our refinement scheme based of the hexahedral form inspired properties is to use auxiliary elements, which are constructed in some practices. The coarse grid tetrahedron is split into four tetrahedrals that are similar to their parent plus one different tetrahedral in the center. Hence, our refinement procedure results are divided into only two classes of similar tetrahedral, implying that mesh quality will never deteriorate. This approach presents an efficiency technique to reduce the size of a regular structure meshing (≈40% is the reduction report). Then, a great gain in memory and time consumption will be obtained (square matrices size will have a total edges divided by 5.1). The entire new technique will be developed in our article. Numerical results presented in this article for a partially loaded waveguide problem will have a great importance to validate the usefulness of this new approach. © 2011 Wiley Periodicals, Inc.

Novel quintuple‐mode broadband microstrip BPF with stub‐loaded multiple‐mode resonator
Authors: Deng Hongwei , Zhao Yongjiu , Zhang Xueshun , Zhang Lu , Lu Xin 
Published: February 2011

AbstractIn this article, a novel compact broadband microstrip bandpass filter with high selectivity and wide upper‐stopband performance is proposed using quintuple‐mode stub‐loaded resonator. The proposed resonator can generate two odd‐modes and three even‐modes in the desired band. The open stub and short‐circuited stub at its central plane can not only specially control the even‐mode resonant frequencies, whereas the odd‐mode ones are fixed, but also generate two transmission zeros near the upper and lower cut‐off frequencies, leading to high rejection skirt. Two identical impedance‐stepped open stubs are mainly applied to adjust the high resonant modes (fm4, fm5) into desired passband and excite one additional transmission zero to deepen the upper‐stopband. A quintuple‐mode broadband filter with the fractional bandwidth better than 64% is simulated, fabricated, and measured. The EM simulated and measured results are presented and excellent agreement is obtained. © 2011 Wiley Periodicals, Inc.

Simultaneous measurement of axial strain and temperature using a PM fiber Bragg grating
Authors: Tong Zhongrong , Zhao Jinting , Yang Xiufeng 
Published: February 2011

AbstractA novel design for simultaneous axial strain and temperature measurement using a PM fiber Bragg grating (PMFBG) concatenated with a Sagnac fiber loop mirror is proposed and demonstrated.The PMFBG acts as a sensor head, and the Sagnac fiber loop mirror serves as a filter to convert wavelength variation to optical power change. By measuring the wavelength difference and power difference of two resonant peak of the PMFBG, simultaneous measurement of axial strain and temperature can be realized. Maximum errors of ±6.821 με and ±0.001°C are reported over 480 με and 60°C measurement ranges, respectively. This scheme has the advantage of low cost, compact configuration, and conveniently using. © 2011 Wiley Periodicals, Inc.
