The dynamic behaviours of a filament in viscoelastic uniform flow were investigated by an immersed boundary-lattice Boltzmann method. effects the Reynolds numbers (Re, ranging from 10 to 200) and Weissenberg number (Wi, 0 1.2) on flapping motion drag lift coefficients studied. It was found that higher inertial effect (larger Re) promotes filament. In addition, major viscoelasticity Giesekus flu...

Okul öncesi fen eğitiminde temalı bilgi veren resimli çocuk kitapları, bilimsel bilgilerin kazandırılmasında ve süreç becerilerinin geliştirilmesinde oldukça önemlidir. Ulusal uluslararası alan yazında yapılmış olan araştırmalar okul öğretmenlerinin fene karşı ön yargılı düşük öz-yeterlik inancına sahip olduklarını, kavram bilgilerinin yeterli düzeyde olmadığını göstermektedir. Bu noktada dönem...
