Abstract To simulate thermocapillary magnetohydrodynamic (MHD) convection in different shallow annular enclosures filled with silicon melt, a 3D numerical approach using an implicit finite volume formulation is used. Radiation emitted upward from the enclosure's free top surface, bottom one heated vertically and subjected to external magnetic field. The steady unsteady MHD flow four ( R = 0.5, ...

Bath application of N-methyl-aspartate induces fictive locomotor activity in the isolated spinal cord preparation of the lamprey, as well as TTX-resistant membrane potential oscillations in many individual neurons. This inherent oscillatory activity is shown to depend on a specific activation of N-methyl-D-aspartate (NMDA) receptors. This activation initiates voltage-dependent, magnesium-requir...

STUDY QUESTION Does calcium oscillatory pattern analysis following heterologous intra-cytoplasmic sperm injection (ICSI) of human sperm into mouse oocytes lead to diagnostic and prognostic information for patients suffering from ICSI fertilization failure? SUMMARY ANSWER We found that calcium oscillatory pattern analysis following heterologous ICSI has the strength to reveal, for the individu...

A recurring pattern of spectral changes indicative of periodic changes in the proportion of beta-structure and a-helix of a recombinant ECTO-NOX fusion protein of tNOX, with a cellulose binding domain peptide, was demonstrated by Fourier transform infrared (FTIR) and circular dichroism (CD) spectroscopic analyses. The pattern of structural changes correlated with oscillatory patterns of enzymat...
