This study investigated the effectiveness of individual and collaborative outputbasedfocus-on-form instructional tasks on the acquisition of English inversionstructures by EFL learners. Moreover, it explored the developmental trend oflearners’ inversion acquisition. To this end, 60 homogeneous EFL learners wereassigned to individual and collaborative output groups. They were exposed to textsenc...

This study explores how identical final CV syllables in C1VC3V C2VC3V word pairs affect speech error patterns. Recent kinematic studies have shown that speakers frequently added non-intended movements to intended articulatory movements during the first consonants of C1VC3 C2VC3 syllables or reduce the range of the intended movements [1, 2, 3]. This effect was especially strong in syllables that...

The aim of this paper is to give a different method from the classic ones for the synthesis of the four-bar guiding mechanism. The method consists of the decomposition of the mechanism into small parts, simple kinematic chains, which are synthesized separately and then we put together the results, obtaining the synthesis of the whole mechanism.

Parent and adolescent (M = 15.7 years) beliefs regarding parents’ right to know (RTK) about adolescents’ activities were examined in 174 middle-class U.S. families. Mean differences and associations with latent changes in teens’ concealment were assessed. RTK was greatest about risky prudential activities, least for personal activities for parents and romantic activities for teens, and higher f...

phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between oil-in-aqueous dispersion and aqueous-in-oil dispersion. a theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. experimental data from the literature were used to validate the model and results were compa...

Helicopter-borne frequency-domain electromagnetic (HEM) surveys are used extensively for mineral and groundwater exploration and a number of environmental investigations. To have a meaningful interpretation of the measured multi- frequency HEM data, in addition to the resistivity maps which are provided in each frequency or for some particular depth levels, it is a necessity ...

We estimate the critical slip-weakening distance on earthquake faults by using a new approach, which is independent of the estimate of fracture energy or radiated seismic energy. The approach is to find a physically based relation between the breakdown time of shear stress Tb, the time of peak slip-velocity Tpv, and the slip-weakening distance Dc, from the time histories of shear stress, slip, ...
