    Notes: Abstract —Geological investigations of coastal sediments indicate that prehistoric tsunamis can be identified. Their characterisation has altered our knowledge of the past frequency and magnitude of tsunamis for different areas of the world. Yet there have been relatively few geological studies of modern tsunamis with virtually no direct observations of the processes associated with tsunami sediment transport and deposition. This paper discusses these issues and draws on the results of recent research to summarise our current knowledge on the nature of tsunami deposits.

    Notes: Abstract  Morphological, electrophysiological and behavioral evidence indicates that the onset of rapid, synchronized conduction of auditory impulses occurs in the human brainstem during the 28th–29th fetal weeks. This implies that axonal connections in the brainstem auditory pathway are generated prior to this time. In order to investigate the sequence of axogenic events in the human brainstem pathway, we employed immunohistochemical techniques and an antibody to neurofilament protein. Immunostaining for axonal neurofilaments in an age-graded series of fetal brains demonstrates that a small number of cochlear nerve axons have invaded the ventral cochlear nucleus by the 16th fetal week. By this same time point, a limited number of trapezoid body-lateral lemniscus axons have reached the superior olivary complex and inferior colliculus. Between gestational weeks 16 and 26, there is marked expansion and collateralization of the ascending pathway from cochlear nerve to inferior colliculus. By week 26, ascending axons have begun to form plexuses of terminal neuropil within all of the brainstem auditory nuclei. Beginning in week 22, there is development of commissural axons (dorsal commissure of the lateral lemniscus and commissure of the inferior colliculus) and descending projections (descending collicular axons and olivocochlear bundle). This early establishment of a mature pattern of axonal connections presumably forms the basis for the appearance of myelin, acousticomotor reflexes and recordable brainstem responses by fetal week 29.

    Advanced primary treatment of waste water using a bio-flocculation-adsorption sedimentation process (2000)
    Berlin : Wiley-Blackwell

    Notes: An advanced primary treatment process for a municipal waste water was systematically studied, using a bio-flocculation-adsorption, sedimentation and stabilzation process (BSS). It was shown that the organic removal efficiency was higher than that of the traditional primary treatment processes but lower than that of the traditional secondary treatment processes. Both adsorption and bio-flocculation played an important role in the removal of pollutants. The activated sludge within the bio-flocculation-adsorption tank could be considered a bio-flocculent which improved the quality of the effluent from the primary treatment process. As the effluent of the BSS process did not meet the requirements for a typical secondary effluent, the process may be regarded as an advanced (or enhanced) primary treatment process, suitable for waste water containing a high concentration of suspended solids and colloidal particles.

    Normal coordinate treatment of Leu5-enkephalin in the crystal state (1993)

    Notes: Vibrational studies on the neuropentapeptide Leu5-enkephalin were performed for the crystal state where different specific conformations can arise. In the present case, the peptide adopts a double fused folded conformation (β-turn), the presence of which in the crystal state is directly related to the nature of the solvent used for its crystallization. This study completes other work relating to similar conformations of isolated molecules. It can be seen that specific interactions in the crystal state perturb to a large extent the vibrational relationships between the amide frequencies and the specific sets of dihedral angles characteristic of the particular type of turn. The tyrosyl moiety and its frequency dependence on its hydrogen bond state was especially investigated both for the Fermi resonance and the hydroxyl bending modes.
