This book, a 302-page compilation of 51 essays regarding renewable and nuclear energy, is easy to read and very informative. The wide spectrum of topics covered in the book will enable the reader to gain a vast general knowledge about nuclear history, basic nuclear principles and major incidents and accidents that have shaped the future of this powerful and controversial energy resource.
Statistics reveal that South Africa has almost double the global average road death toll per capita, which is quite frightening considering our socioeconomic circumstances (Vanderschuren et al 2011). South Africa spends R52 billion on road crashes and fatalities annually; it is therefore clear that road safety investments are warranted (Tsedu 2009). Clear demarcation and visibility on our roads have proved to reduce accidents.
Cape Town needs a safe, affordable, efficient public transport system. Capetonians make over one million trips every day by train, bus and minibus taxi, but these services are not safe, frequent or predictable enough. Meanwhile, those commuting by car are facing ever-increasing delays due to congestion. The City of Cape Town cannot continue building roads to accommodate the rising numbers of cars.
Two years ago the SAICE Western Cape Branch Committee developed a website with the aim of keeping SAICE Western Cape members informed of upcoming events, branch contacts, competition entry forms, and providing feedback to branch members on events.

SAICE Honorary Fellow Faried Allie, who passed away on 6 June after a long illness, was not only SAICE's centenary president in 2003, but served the Institution in various other capacities over many years. He was the first president to come from the ranks of the engineering technologists after the merger of SAICE and SAICET (South African Institute of Civil Engineering Technicians and Technologists) in the early nineties.
Referred to by colleagues as "South Africa's principal ground anchoring expert" and a "trailblazer in geotechnics", Dr Ross Parry-Davies passed away peacefully, aged 88, in his home on 27 July 2012. He is survived by his much loved wife of sixty years, Renée, their children Janice, Megan and David, and their close, loving family.
Ever since the publication in 1940 of papers by J E Stanton on the influence of cement-aggregate reaction on the expansion of concrete, interest in the alkali content of Portland cements as a cause of expansion through reaction with certain reactive silica constituents in the aggregate has been widespread.
This paper details the results of a geotechnical investigation into the instability of a cutting (in the Ecca Series) between Paul Pietersburg and Vryheid on the new Broodsnyersplaas - Richards Bay railway line. The main activating agent for the instability was found to be a saturated groundwater condition and the design of a dewatering system to reduce the phreatic surface is detailed.
The planning of large developments requires that a functional approach should be made in considering the capacity of the interfacing traffic facilities. An example of the application of such an approach is given and comparisons are made with overseas research of a similar kind to show there is a reasonable degree of stability between different countries in the use of the private motor car for the journey to work by the different occupation groups. The inadequacy of some of the more conventional planning parameters are also illustrated.
Formal education in construction management was Initiated in 1947 by Prof C H Oglesby at the University of Stanford, who built the Stanford's Programme into a school with a world-wide reputation by the time of his retirement in 1975. Today construction management programmes are offered by many reputable overseas civil engineering faculties.
