In the year 1845, the Committee of Physics of the Royal Society having expressed a wish that a Magnetic Survey should be made of the East Indian Archipelago, Captain Elliot was ordered by the Court of Directors of the East India Company to undertake that duty, after the close of the Singapore Magnetic Observatory. The observations at that observatory were discontinued at the end of the year 1845, but the instruments were still allowed to remain, that the portable instruments might be occasionally compared with them during the Survey. The object which the author proposed to himself was the determination of certain magnetic lines within the limits of the Survey: the lines of no dip, and of the maximum horizontal component of the earth’s force; the minimum intensity of the total magnetic force; and finally, the line of no declination. He was also desirous of observing the variations of the magnetic elements, and of ascertaining whether the changes of the declination, of magnetic intensity, and of the barometer, were uniformly similar over so large an area.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.

Magnetic Field Computation

The paper presents numerical modeling of an Axial Active Magnetic Bearing (AAMB) based on two-dimensional (2D) magnetic field computation. The calculations, assisted by the Finite Element Method (FEM), have focused on the determination of the magnetic flux density and the magnetic force. Obtained magnetic field parameters were then measured and verified on a physical model.

The dipping of sheep and cattle, as a means of eradicating ‘scab,’ lice, ticks, etc., and the diseases which it is now known the latter may transmit, has met with such success, that compulsory dipping is now in vogue in most pastoral countries. Where compulsory dipping obtains, there must of necessity be some system of the standardisation of dips. In Queensland and South Africa, the respective Governments issue official formulae from which the stockbreeder can prepare his own dipping fluid. Only such proprietary dips, as are duly recognised by the Government, may be employed. In the United States, the regulations for the sale of proprietary dips are still more stringent. The quantity of active substance, usually sodium arsenite, nicotine or cresylic acid, is defined within very narrow limits. Further, no proprietary dip is now recognised, unless the manufacturer can furnish a ‘Field Tester,’ by means of which the stockbreeder can himself determine, in a simple and fairly trustworthy manner, the percentage of active constituent in his bath.

International Marketing Strategy

Given that culture is an important factor in the international environment, it is a necessity that culture be well understood in order to achieve success in international marketing strategies. Previous research focused more on the broader influence of culture on marketing strategies, with few studies focusing on the way in which culture and marketing affect and are effected by one another, culture’s role in the localisation or standardisation of a marketing strategy, as well as which elements of the marketing strategy to standardise versus localise. The sample was drawn from key employees working within reputable multinational organisations in South Africa. No hypotheses were formulated or tested but instead this exploratory study identified areas, which have not been researched in South Africa and eight propositions based on the findings were formulated. The findings indicate that culture plays a very important role in the overall formulation of an international marketing strategy, and it was not conclusive whether such a strategy should be standardised or whether it should be localised. Generally, the responses suggest that a marketer’s strategy should suit the local culture in order to reach them and have the desired effect on the target market, and not the other way around because such evolutions could take an extensive amount of time in order to achieve marketing goals.
