Technological innovations, which in the nineteenth century were principally developed by European nations, were a crucial factor in transforming economies – not only those of the countries in which they originated, but also those of their colonies. This case study of Nigeria explores the way the British controlled the colony and subjugated the local people as a result of their superior technology. Upon taking over the territory, to aid the country's economic development, they began to construct railway lines to link major resource zones of the north and south. This facilitated the more efficient shipment of natural resources from these zones to the coastal ports for onward shipment to Britain. Indigenous production and the rendering of palm oil were transformed by the introduction of oil presses. The article examines the transformative impact of technology in resource exploitation, focusing specifically on railways and oil presses and their impact on Nigerian society.

Equipped with type AEM-RS electromagnetic current meter, the buoy provided effective technical platform for on-site rapid monitoring of the ocean current. Performance index and usage in the ocean current buoy of AEM-RS was introduced. Ultrasonic cleaning method in seawater was developed for preventing AEM-RS from biofouling. Ocean current data can serve for oceanographic research and marine resource exploitation.
