Comparing the Effects of Structural and Natural Language Use during Direct Instruction with Children with Mental Retardation
(1998)
Effects of structural and natural language use during direct instruction in teaching color and shape concepts to children with moderate mental retardation were compared using an adapted alternating treatments design. ...
Lichens of the Akşehir disatrict (Konya)
(1998)
Konya ili, Akşehir ilçesinde yapılan çalışmada 33 cinse ait 89 liken türü belirlenmiştir. Bu türlerden Staurothele frustulenta Vainio Türkiye Liken Florası için yeni kayıttır.
Lichens of the Akşehir District (Konya)
(1998)
Eighty-nine lichen species belonging to 33 genera from Akşehir District of Kenya were determined. Staurothele frustulenta Vainio is a new record for the lichen flora of Turkey.
Effect of starting composition, type of rare earth sintering additive and amount of liquid phase on alpha reversible arrow beta sialon transformation
(Elsevier Sci LTD, 1997)
Five different alpha-beta sialon and alpha-sialon compositions have been prepared using different rare earth oxide additives namely, neodymium, samarium, dysprosium and ytterbium., Post-sintering heat treatments have been ...
The effect of heat-treatment on the performance of sub-micron SiCp-reinforced alpha-beta sialon composites .1. Preparation of agglomerate-free starting powders
(Elsevier Sci LTD, 1997)
In order to prepare good-quality, dense, SiCp-reinforced alpha-beta sialon composites by hot-pressing, a technique was developed to prevent agglomeration of the SiC grains during powder processing. For this purpose, the ...
Comparing the effects of structural and natural language use during direct instruction with children with mental retardation
(Council Exceptional Children, 1998)
Effects of structural and natural language use during direct instruction in teaching color and shape concepts to children with moderate mental retardation were compared using an adapted alternating treatments design. ...
New developments in alpha-SiAlON ceramics
(Elsevier Sci LTD, 1999)
Two different alpha-sialon compositions have been densified by either pressureless sintering or capsul-free sinter HIPing using either single cation namely strontium, lanthanum, cerium, neodymium or their equimolar mixtures ...
Cyclic crack growth behaviour of two nickel base turbine disc alloys
(Kluwer Academic Publ, 1998)
The high temperature fatigue crack growth behaviour of the nickel base superalloys Alloy 718 and Rene 95 (specimen thickness = 4.1 mm) were investigated and compared with each other. Fatigue crack propagation (FCP) tests ...
Reactions at ceramic-metal interfaces in capacitor-discharge joined ceramics
(Transtec Publications LTD, 1999)
A capacitor-discharge joining technique has been used to fabricate zirconia-AlxNiyYz zirconia (ZrO2) joints, in addition, the surface of the ZrO2 tiles were sputter coated with Ti and joined using Al as an interlayer ...
alpha ->beta sialon transformation in calcium-containing alpha-SiAlON ceramics
(Elsevier Sci LTD, 1999)
Recent studies on rare earth densified a-sialon ceramics have shown that the resulting alpha-sialon product, present either as a single phase or in conjunction with beta-sialon, is unstable when heat treated at lower ...
