das erlernen einer zweiten sprache neben der erstsprache, n?mlich der muttersprache, gilt als zweitspracherwerb. man kann verschiedene formen des zweitspracherwerbs unterscheiden und zwar je nachdem, in welchem alter, auf welche weise, mit welchen zielen und bis zu welchem grad der sprachbeherrschung die neue sprache gelernt wird. aber es spielt eine besonders gro?e rolle, ob diese neue sprache...

A new approach for analyzing cracked problems in 2D orthotropic materials using the well-known element free Galerkin method and orthotropic enrichment functions is proposed. The element free Galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. In this study, element free Galerkin is extrinsically enriched by the recently developed crack-tip orthot...

A stable isotope study was carried out seasonally in three coastal ponds (Marinello system, Italy) affected by different gull guano input to investigate the effect of nutrient subsidies on food web structure and dynamics. A marked 15N enrichment occurred in the pond receiving the highest guano input, indicating that gull-derived fertilization (guanotrophication) had a strong localised effect an...

PPurpose: The purpose of this study is to investigate the effect of both work to family enrichment and family to work enrichment on family satisfaction and work satisfaction. The moderating role of positive and negative affectivity is also examined in this regard. Methodology: This Study is an empirical survey research with the statistical population of faculty members of Iran’s universities. ...

this study was carried out to evaluate the effect of probiotic (bacillus latrospores and bacillus licheniformis) on growth and survival of silver carp larvae (hypophthalmichthys molitrix). rotifers (brachionus plicatilis) were used as live prey vehicle for probiotic transport. they were cultured in sea water with 15 ppt salinity and nannochloropsis oculata microalgae was used as feed. five trea...
