Mispronunciation is still among the frailties of language learners the world over. The present study reports an all-out investigation into pronunciation training for the Persian-speaking EFL learners at the intermediate level of language proficiency. More specifically, the present study investigated (a) the underlying causes of mispronunciation at the level of segmental features, (b) the crucia...

Recently, a polar, rod-like liquid-crystalline material was reported to exhibit two distinct nematic mesophases (termed N and NX ) separated by a weakly first-order transition. Herein, we present our initial studies into the structure-property relationships that underpin the occurrence of the lower-temperature nematic phase, and report several new materials that exhibit this same transformation...

Homogenized pastes were prepared by adding top-bond white glue as binder to natural fibrous material prepared out of different proportions of bamboo (Ozizentera arbonica), coconut husk (Cocus nucifera), sponge (Acanthus montanus) and wood (cordial). Test samples were prepared from dried cast samples for creep and hardness tests. The results of the analysis were used to determine the material th...

We report the first example of a donor-acceptor corannulene-containing hybrid material with rapid ligand-to-ligand energy transfer (ET). Additionally, we provide the first time-resolved photoluminescence (PL) data for any corannulene-based compounds in the solid state. Comprehensive analysis of PL data in combination with theoretical calculations of donor-acceptor exciton coupling was employed ...

BACKGROUND The skin prick test (SPT) is a valid and approved tool that is used to diagnose atopic diseases. The SPT is accurate, safe, simple and inexpensive. However, the histamine concentration used as a positive control in the SPT varies among centers. OBJECTIVE To compare SPT results using different concentrations of locally-prepared and imported histamine solutions. METHOD This prospec...
