    Speaking competence a productive skills. However, the associated with teaching materials in the books Minna no Nihongo 1 renshuu C are expected discrepancy that competence in conversations class. That is can't be fulfilled when referring to competence in according with JF Standard. So in this qualitative research to compare between the two textbooks Minna no Nihongo 1 with Marugoto A1 katsudou. Because the basic level of speaking competence indicator is able to perform a simple conversation, slowly and repeated, replacing the phrase, giving a help, being able to ask questions about important issues, and using daily topics in the basic conversation. And that should be a concern the purpose of making the material isn't the same as conversation learning with sentence patterns or grammar learning basically. And than the books Minna no Nihongo 1 renshuu C, that's material noticed how communication targets to be achieved in each meeting

    ISO 9164 heat loss in roof-wall sections

    In the simple ISO 9164 calculation procedure for transmission heat loss coefficient, HT, it is unclear, and undefined for floor or roof-wall sections, how the parameters in the equations will be calculated. In this paper, a method is proposed for the calculation of ISO 9164 parameters for roof-wall sections. The results obtained by the proposed method for typical roof sections are compared with those obtained by the EN 832/EN 13789/EN ISO 14683 methods and with the L2D values from 2D analysis. A comparison of the floor and roof behaviour is realized using the results of the present and the previous works of the authors. The HT values obtained by the proposed model using the sum of qy through the beam are harmonised with the L2D for floors, which are significantly different from the L2D for roofs with parapet. The results indicate that the L2D values cited in EN 10211-1 are sensitive to the 2D heat flows for floor sections. However, the L2D is not sufficiently sensitive to heat flow from the beam to the parapet and the interactions between the zones within the beam section, whereas the proposed method is more sensitive to the 2D heat flows. © 2011 Academic Journals

    Cataloged from PDF version of article.The combination of nanomaterials and conducting polymers attracted remarkable attention for development of new immobilization matrices for enzymes. Hereby, an efficient surface design was investigated by modifying the graphite rod electrode surfaces with one-step electrospun nylon 6,6 nanofibers or 4% (w/w) multiwalled carbon nanotubes (MWCNTs) incorporating nylon 6,6 nanofibers (nylon 6,6/4MWCNT). High-resolution transmission electron microscopy study confirmed the successful incorporation of the MWCNTs into the nanofiber matrix for nylon 6,6/4MWCNT sample. Then, these nanofibrous surfaces were coated with a conducting polymer, (poly-4-(4,7-di(thiophen-2-yl)-1H-benzo[d]imidazol-2-yl) benzaldehyde) (PBIBA) to obtain a high electroactive surface area as new functional immobilization matrices. Due to the free aldehyde groups of the polymeric structures, a model enzyme, glucose oxidase was efficiently immobilized to the modified surfaces via covalent binding. Scanning electron microscope images confirmed that the nanofibrous structures were protected after the electrodeposition step of PBIBA and a high amount of protein attachment was successfully achieved by the help of high surface to volume ratio of electroactive nanofiber matrices. The biosensors were characterized in terms of their operational and storage stabilities and kinetic parameters (K mapp and Imax). The resulting novel glucose biosensors revealed good stability and promising Imax values (10.03 and 16.67 μA for nylon 6,6/PBIBA and nylon 6,6/4MWCNT/PBIBA modified biosensors, respectively) and long shelf life (32 and 44 days for nylon 6,6/PBIBA and nylon 6,6/4MWCNT/PBIBA modified biosensors, respectively). Finally, the biosensor was tested on beverages for glucose detection. © 2014 American Chemical Society

    Probing new physics with coherent neutrino scattering off nuclei

    Full text link
    The possibility off measuring for the first time neutrino-nuclei coherent scattering has been recently discussed by several experimental collaborations. It is shown that such a measurement may be very sensitive to non-standard interactions of neutrinos with quarks and might set better constraints than those coming from future neutrino factory experiments. We also comment on other types of new physics tests, such as extra heavy neutral gauge bosons, where the sensitivity to some models is slightly better than the Tevatron constraint and, therefore, could give complementary bounds.Comment: 15 pages, 4 figures Discussion about Z prime corrected and extended.

    Magnetic reconnection with anomalous resistivity in two-and-a-half dimensions I: Quasi-stationary case

    Full text link
    In this paper quasi-stationary, two-and-a-half-dimensional magnetic reconnection is studied in the framework of incompressible resistive magnetohydrodynamics (MHD). A new theoretical approach for calculation of the reconnection rate is presented. This approach is based on local analytical derivations in a thin reconnection layer, and it is applicable to the case when resistivity is anomalous and is an arbitrary function of the electric current and the spatial coordinates. It is found that a quasi-stationary reconnection rate is fully determined by a particular functional form of the anomalous resistivity and by the local configuration of the magnetic field just outside the reconnection layer. It is also found that in the special case of constant resistivity reconnection is Sweet-Parker and not Petschek.Comment: 15 pages, 4 figures, minor changes as compared to the 1st versio
