In a series of previous articles, one of the authors published designs of the AB Dome which can cover a city, important large installations or subregions by a transparent thin film supported by a small additional air overpressure. The AB Dome keeps the outside atmospheric conditions from the interior protecting a city from chemical, bacterial, and...

The results of heat transfer to supercritical water flowing upward in a vertical annular channel (1-rod channel) and tight 3-rod bundle consisting of the tubes of 5.2-mm outside diameter and 485-mm heated length are presented. The heat-transfer data were obtained at pressures of 22.5, 24.5, and 27.5 MPa, mass flux within the range from 800 to 3000...

... In all cases, the problem of damage is a general one arising from cells interacting with their fluid environment (Zhang and Thomas, 1993) as formalised in the wall-strength model for microbial cell disruption (Middelberg et al., 1992a,b). On a larger scale, elliptical shells can also be used as air-inflated building structures (Bolonkin and Cathcart, 2007;Bolonkin et al., 2011;Kozicki and Kozicka, 2011) which are dome-shaped as they provide the greater surface area under the structure for a minimum amount of material. The applications of planar elastic pockets are therefore very diverse. ...
A circular silicone sheet is clamped at its edge and pressurised by the injection of a liquid beneath creating a pocket. We study experimentally the deformation and pressure increase caused by the compression of a pressurised pocket. Excellent agreement is found between experimental observations and numerical predictions based on an axisymmetric thin hyperelastic material; an approximate analytical model explains the link between changes in shape and the applied force.
Prefabricated volumetric modular building construction is an emerging technology in many countries used to develop the construction industry through its value-added benefits. The adoption of these novel technologies in the Sri Lankan construction industry has been relatively slow compared with other developing countries, delaying the development of the construction industry and the attainment of the added benefits of these technologies. Therefore, this study aims to identify the suitability of modular construction for the Sri Lankan construction industry via a survey and case study. A questionnaire survey was developed and distributed to assess and identify the benefits of implementing the concepts and constraints in Sri Lanka. Then, the construction cost of a proposed single-story house delivered through conventional and modular practices was compared. The survey results showed that introducing a modular concept to the industry is suitable and would benefit the Sri Lankan construction industry. Further, survey participants believed that the economic benefits brought in by modular construction are significantly more important than environmental and social benefits when selecting modular construction. The case study on a single-story affordable modular house showed a 32% reduction in total construction costs and a 36% reduction in labour costs compared to conventional house construction. Further, costs for total modular construction and labour were 32% and 36% less than those of conventional construction costs and labour costs. Moreover, a 16% reduction in embodied energy was observed when compared with conventional construction. Therefore, the modular concept could be used to construct affordable houses and will be cost-effective with the correct choice of material.
