This study aims to determine the development of Arabic language textbooks based on Multiple Intelligences at Madrasah Ibtidaiyah/Islamic Elementary School level and effectiveness their use in classroom. research is problem finding that some used schools are still less effective for learning Arabic. In level, there many long texts istima', kalam, qiro'ah so they not suitable basic learners. Some...

There is variability in the Mg isotopic composition that is a reflection of the widespread heterogeneity in the isotopic composition of the elements in the solar system at approximately 100 ppm. Measurements on a single calcium-aluminum-rich inclusion (CAI) gave a good correlation of Mg ⁄ Mg with Al ⁄ Mg, yielding an isochron corresponding to an initial (Al ⁄ Al)o = (5.27 ± 0.18) · 10 and an in...

Precipitation strengthening is investigated in binary Al–0.1Sc, Al–0.1Zr and ternary Al–0.1Sc–0.1Zr (at.%) alloys aged isochronally between 200 and 600 C. Precipitation of Al3Sc (L12) commences between 200 and 250 C in Al–0.1Sc, reaching a 670 MPa peak microhardness at 325 C. For Al–0.1Zr, precipitation of Al3Zr (L12) initiates between 350 and 375 C, resulting in a 420 MPa peak microhardness at...
