The separation of wave modes from isotropic elastic wavefields is typically done using Helmholtz decomposition. However, Helmholtz decomposition using conventional divergence and curl operators in anisotropic media does not give satisfactory results and leaves the different wave modes only partially separated. The separation of anisotropic wavefields requires the use of more sophisticated opera...

The effect of acetate ion introduced to aqueous solutions was investigated for the extraction/separation of Ni and Co from a dilute sulfate media. The separation of Co and Ni was improved by introducing acetate to aqueous media. By the use of the slope analysis method,the stoichiometric coefficient of the extractant was found to be 4 for cobalt and 3.5 or 4 for nickel depending on the aceta...

Technology has the potential to impact cognition in many ways. Here we contrast two forms of technology usage: (1) media multitasking (i.e., the simultaneous consumption of multiple streams of media, such a texting while watching TV) and (2) playing action video games (a particular subtype of video games). Previous work has outlined an association between high levels of media multitasking and s...

Water enriched with its natural isotopes plays an important role in research and technology. Heavy water (HDO, D2O) is used in nuclear technology and research and the increasing market demand is expected in future if nuclear fusion will be used for energy production. Water enriched in O is used in research and medicine in trace experiments, as is water enriched in O. Recently there appears to b...
