Abstract Research in termoacoustics began with the observation of the heat transfer between gas and solids. Using this interaction the intense sound wave could be applied to create engines and heat pumps. The most important part of thermoacoustic devices is a regenerator, where press of conversion of sound energy into thermal or vice versa takes place. In a heat pump the acoustic wave produces the temperature difference at the two ends of the regenerator. The aim of the paper is to find the influence of the material used for the construction of a regenerator on the properties of a thermoacoustic heat pump. Modern technologies allow us to create new materials with physical properties necessary to increase the temperature gradient on the heat exchangers. The aim of this paper is to create a regenerator which strongly improves the efficiency of the heat pump.

The focus of research has mainly been on the life cycle approach to project development, while limited attention has been given to the ageing construction companies that make all these activities/processes happen. This paper examines the organisational factors determining the sustainability and growth of building and civil engineering contractors in South Africa. The paper explores whether there are specific organisational factors that aid the sustainable development and growth of contractors in the South African construction industry. The paper analyses data gathered from face-to-face interviews conducted with four established and twelve upgraded and successful building and civil engineering contractors listed on the Construction Industry Development Board’s (cidb) Register of Contractors. The aim of the study is to identify the organisational factors critical for sustainable contractor development and growth in South Africa. The study found that organizational factors responsible for the sustainable development and growth of construction contractors include the size of the founding team members, management capabilities, strategic decisions made by founders/leaders and the ability of the company to constantly evolve, adapt and respond effectively to threats/challenges whenever they surface, amongst other findings. Capacity to generalise the results of the study to the large cidb registered contractor group is limited by the smallness of the sample size. Future research should make use of a larger sample size to obtain more general findings. The results of the study imply that the founding team size, experience, entrepreneurial and managerial capabilities, capacities and organisational structures that enable the efficient response of companies to external and internal challenges are key components of the definable arrangements that will support the sustainability and growth of construction organisations. The paper is of value to government departments and agencies such as the cidb and contracting firms in the construction industry.

Sir William Glanville, who died on 30 June 1976, was a pioneer in the modern age of civil engineering which developed after World War I. Before that, apart from the introduction of new materials, cast iron, wrought iron, mild steel and reinforced concrete, all of which in their turn, in the hands of brilliant and daring designers, made new forms of structure possible, there had been little advance in the basic art of the civil engineer for a hundred years. Truly empirical methods, which were so valuable in the development of mechanical and electrical engineering, were ruled out by the magnitude of the products—roads, bridges, dams, sea defences and the like—of what is now classed as civil engineering, while the dearth of suitable instruments had made full-scale testing impossible. William Henry Glanville, who was born on 1 February 1900, was the only son of a London builder of Cornish extraction. He was educated at Kilburn Grammar School and after a brief period of army service at the end of World War I he became a student at East London College (Queen Mary College), University of London, from which he graduated in 1922 with a first class honours degree in civil engineering. Instead of seeking practical experience on site or in the office of a practising civil engineer he took what was then the unusual step of going straight into a research establishment.

The success of any new build project is reliant upon all stakeholders — applicants, vendors, contractors and regulatory agencies — being ready to do their part. Over the past several years, the Canadian Nuclear Safety Commission (CNSC) has been working to ensure that it has the appropriate regulatory framework and internal processes in place for the timely and efficient licensing of all types of reactor, regardless of size. This effort has resulted in several new regulatory documents and internal processes including pre-project vendor design reviews. The CNSC’s general nuclear safety objective requires that nuclear facilities be designed and operated in a manner that will protect the health, safety and security of persons and the environment from unreasonable risk, and to implement Canada’s international commitments on the peaceful use of nuclear energy. To achieve this objective, the regulatory approach strikes a balance between pure performance-based regulation and prescriptive-based regulation. By utilizing this approach, CNSC seeks to ensure a regulatory environment exists that encourages innovation within the nuclear industry without compromising the high standards necessary for safety. The CNSC is applying a technology neutral approach as part of its continuing work to update its regulatory framework and achieve clarity of its requirements. A reactor power threshold of approximately 200 MW(th) has been chosen to distinguish between large and small reactors. It is recognized that some Small Modular Reactors (SMRs) will be larger than 200 MW(th), so a graded approach to achieving safety is still possible even though Nuclear Power Plant design and safety requirements will apply. Design requirements for large reactors are established through two main regulatory documents. These are RD-337 Design for New Nuclear Power Plants, and RD-310 Safety Analysis for Nuclear Power Plants. For reactors below 200 MW(th), the CNSC allows additional flexibility in the use of a graded approach to achieving safety in two new regulatory documents: RD-367 Design of Small Reactors and RD-308 Deterministic Safety Analysis for Small Reactors. The CNSC offers a pre-licensing vendor design review as an optional service for reactor facility designs. This review process is intended to provide early identification and resolution of potential regulatory or technical issues in the design process, particularly those that could result in significant changes to the design or analysis. The process aims to increase regulatory certainty and ultimately contribute to public safety. This paper outlines the CNSC’s expectations for applicant and vendor readiness and discusses the process for pre-licensing reviews which allows vendors and applicants to understand their readiness for licensing.

The environmental awareness and potential cost reduction have promoted the recycling of materials in civil engineering. This paper is dealing with the recycling and secondary use of old concrete railway sleepers for reconstruction of old railway lines. In particular, it is focused on the investigation of material properties of a binder prepared from finely crushed old concrete sleepers. This material could be used for strengthening of subsoil and embankments supporting the railway structures. The study shows that the compressive and bending strength of the investigated material is sufficient for this purpose and that the strength can be further increased by suitable curing conditions. These findings could contribute to the utilization of old concrete sleepers during railway reconstructions and safe money spent for the purchase of new materials and disposal of old sleepers.
