Ferranti and Merz were the architects of power transmission system design in Britain. Ferranti's design concept broke through the parochial model of electricity supply inherent in the Electricity Lighting Acts of 1882 and 1888. Although the concept of a remote high-power central station with high-voltage transmission and large-area distribution was not realised by Ferranti in 1889, it was realised by the power companies. Merz was foremost in using the Ferranti design concept in 1901 for the Newcastle, later the North East, Electric Supply Company (NESCo.). Later Merz introduced a new radical concept by the interconnection of a number of power stations. He did this first for NESCo. And in 1916 he proposed this as a model to be adopted for British electrification. Merz was unique in first solving the technical problems of power station interconnection and then realising that such a transmission system best suited an electricity supply for the industrial areas of Britain. - Author(s): C.T.

It is widely known that the electricity supply industry in Great Britain was nationalised (Electricity Act, 1947) by a Labour government in accordance with Clause 4 of the Party's then Constitution but there are other reasons why a large-scale reorganisation was needed. It is well-known, too, that the newly nationalised industry had problems in engineering, but there were also other problems. In this paper, the author discusses some of these other problems in which he was involved. Firstly, however, he gives a brief word about the industry's history. - Source: Engineering Science & Education Journal, Volume 7, Issue 1, page: 18 –18

Microengineering started as a field of study of devices which exploited the mechanical properties of silicon. In particular, sensors, of which pressure sensors and accelerometers are the two greatest commercial successes to date, became a very popular field of study. The subject of actuation in microengineering is now attaining equal importance with that of sensors; examples of commercially exploited devices include inkjet printer nozzles, micromirrors, pumps, valves, bimorphs and gyroscopes. This paper reviews the subject of actuation in microengineering, in terms of the factors to consider, the mechanisms and materials involved, example structures and a comparison of the advantages and drawbacks associated with each actuation system. - Source: Engineering Science & Education Journal, Volume 7, Issue 1, page: 28 –28

Hydroelectric power is one of the most widely exploited forms of renewable energy and, in areas where global climate change (GCC) causes precipitation characteristics to change significantly, or more importantly, where run off is reduced, existing hydroelectric installations may require replacement with alternative sources of power. As economic appraisals of new hydroelectric projects are normally made on a long-term basis, GCC may also necessitate revision of assessments of unexploited hydroelectric potential. This paper considers two geographic regions where significant climate change may occur and assesses how possible future precipitation distribution and water run-off may affect the viability of hydroelectric power. - Author(s): J.N.

The potential lifetime of hip replacements is reduced by aseptic loosening-an inadequate fixation of the implant. Increasing the life of the surgical procedure requires knowledge of the interaction between prosthesis and femur. The authors have used electronic speckle pattern interferometry (ESPI), a laser-based metrology technique developed for the analysis of displacements and strains, to develop an understanding of the biomechanics of the proximal femur whilst mounted in a compression test rig which also simulates muscle and tendon behaviour. Cadaveric femora were studied under physiological loads, before and after the implantation of the femoral component of a total hip replacement. - Author(s): K. Brown

The educational requirements for engineers have steadily increased and professional engineering is now a graduate profession. There have been two major reviews of the profession: the Finniston Enquiry, and the Engineering Council review which led to the publication of SARTOR 97 (Standards and Routes Towards Registration). Both reviews followed major expansions in higher education and concerns about educational standards. This paper analyses the evidence for qualification drift in both A-levels and degree output classifications. The effect of SARTOR 97 on university departments is considered and a major shake-out predicted.
