Hierdie artikel bespreek die agtergrond van opvoedkundige tegnologie en die trefkrag daarvan op alle fasette van die onderwys. Daar word definisies gegee van “ opvoedkundige tegnologie” in die ruim ste sin van die woord en ook van opvoedkundige tegnoloé. B loom se taksonom ie van opvoedkundige doelstellings op die kognitiew e en affektiew e terreine word met betrekking tot die ontwikkeling van ...

abstract snp typing is now a well-established genotyping system in bacillus anthracis studies. in the original standard method of van erth, snps at 13 loci of the b. anthracis genome were analyzed. in order to simplify and make appropriate this expensive method to low-budget laboratory settings, 13 primer pairs targeting the 13 corresponding snps were designed. besides, a universal pcr protocol...

Combining direct surface force measurements with in situ regulation of surface potential provides an exceptional opportunity for investigating and manipulating interfacial phenomena. Recently, we studied the interaction between gold and mica surfaces in water with no added salt, while controlling the metal potential, and found that the surface charge at the metal may vary, and possibly even cha...

The van Lambalgen theorem is a surprising result in algorithmic information theory concerning the symmetry of relative randomness. It establishes that for any pair of infinite sequences A and B, B is Martin-Löf random and A is Martin-Löf random relative to B if and only if the interleaved sequence A ⊎ B is Martin-Löf random. This implies that A is relative random to B if and only if B is random...
