the daily record of geomagnetic variations at any world location typically shows a multitude of irregular changes in the field that represent the superposition of many spectral components whose amplitudes generally increase with increasing period. it has been a long established fact that variations in ground magnetic records are caused by the dynamo action in the upper atmosphere. these daily v...

High-resolution records of the upper Olduvai geomagnetic field reversal were obtained from two localities within steeply dipping lacustrine sediments of the Confidence Hills, southern Death Valley, California . The difference in bedding attitude between the two localities allowed us to perform a fold test of both transitional and non-transitional paleomagnetic directions. This is the first posi...

HIMAA members will be aware that the Education Services Division of HIMAA provides an important service to them and to the wider community in offering a suite of training courses in relevant areas. Currently, distance education courses are focused on clinical classification (including medical terminology as a preparatory step in coder training) for the Australian environment as well as certain ...

This paper summarizes the lessons learned from a full-scale test on two RC frame prototypes that have recently been tested on LNEC shaking-table using four pairs of biaxial synthetic ground motion records during 15WCEE Conference (2012). The reference structures are two single-story RC frames which are geometrically identical but with different reinforcement details. The simplified inelastic mo...

The use of a steep Trendelenburg position is described in removing foreign bodies from the foot. Bleeding at the site is sufficiently reduced to allow removal without a tourniquet. Retrospective analysis of theatre records demonstrates a considerable reduction in the number of general anaesthetics given since the introduction of this technique.
