Characterization of interfacial strength of syntactic foam by unit cell finite element model

The interfacial strength between glass hollow microspheres and epoxy in epoxy-based syntactic foam was investigated using finite element method. The stiffness of the foam in tension and compression was studied by unit cell type finite element model containing a microsphere and an epoxy matrix. The changes in the stiffness of the foams having different interfacial strength were analyzed by introducing interfacial elements between the microsphere and the matrix in the model. The tension and compression moduli of the foam was studied by the model, in terms of the stiffness of the interfacial elements. Finally, the moduli of the foam having different volume fractions of the microspheres were evaluated by experiments and compared to the results of the model to characterize the interfacial strength between the microsphere and the matrix.

Seagrass communities in the Shoalwater Bay region, Queensland: Spring (September) 1995 and Autumn (April) 1996

The Commonwealth Commission of Inquiry into Shoal water Bay (Commission of Inquiry 1994) recommended equal priority be given to conservation and defence force training use in the Shoalwater Bay area, and that integrated management plans be developed for the terrestrial and marine environments. The Great Barrier Reef Marine Park Authority (GBRMPA) was given responsibility for developing management plans for a special Shoalwater Bay Marine Park. The GBRMPA commissioned a number of studies of marine resource inventories and use patterns in the Shoalwater Bay area for marine park zone planning. The present Spring and Autumn baseline surveys of seagrass resources is one of these studies. Seagrasses have seasonal differences in distribution and abundance, so two baseline surveys Spring (pre-wet) and Autumn (post-wet) - were recommended. This report presents the results of the two surveys conducted September 1995 and April 1996. The objectives were: to map the distribution of seagrass meadows in Shoa/water Bay during the Spring and Autumn periods; to estimate seagrass species biomass for the major seagrass meadows; to identify juvenile prawn and fish species present on selected seagrass areas; and to provide quantitative data 011 seagrass communities of Shoalwater Bay for use as a baseline for future monitoring of seagrass species composition, area or biomass

Monitoring Oyster Point seagrasses : 1995 to 1999

In the present report, an assessment of changes in seagrass distribution and abundance since the baseline (November 1995) and previous monitoring surveys of December 1997 and November 1998 is included. We provide a quantification of changes between years and comment on the possible impacts of the dredging program

Seagrass and marine resources in the Dugong protection areas of Upstart Bay, Newry Region, Sand Bay, Llewellyn Bay, Ince Bay and the Clairview Region, April/May 1999 and October 1999

The Marine Plant Ecology Group (Queensland Fisheries Service, Queensland Department of Primary Industries) was commissioned by the Great Barrier Reef Marine Park Authority to undertake two (one autumn and one spring) detailed seagrass surveys of the Dugong Protection Areas in Upstart Bay, Newry region, Sand Bay, Llewellyn Bay, Ince Bay, and a reconnaissance survey in the Clairview region. The information gathered from these surveys enhances the understanding and subsequent management of seagrass resources for fisheries and as dugong feeding habitats

The handicap of lists, QROM and the future

Purpose – The purpose of this paper is to consider the contribution that this journal has made to the development of qualitative research over the ten years of Qualitative Research in Organizations and Management’s (QROM’s) lifetime and its potential to contribute further in the future. Design/methodology/approach – Reflections are made from the author’s standpoint as a longstanding associate editor of QROM and a UK academic in the field of accounting. Findings – Concern is expressed about the way in which the use of a particular journal list in UK institutions – namely, the ABS list – has skewed development away from qualitative research during the hitherto lifetime of QROM but how, despite that handicap, QROM has made a notable contribution. Originality/value – A reflection informed by both the disciplinary and geographical context as well as ten years’ service as an Associate Editor of this journal

Preliminary evaluation of an acoustic technique for mapping tropical seagrass habitats

Seagrass meadows in Queensland are important nursery habitat for commercial species of penaeid prawns and fish. Seagrasses are essential food for dugong, Dugong dugon, and green sea turtles, Chelonia mydas (Linnaeus) and act as nutrient and sediment sinks. Seagrasses in coastal regions play important roles in maintaining sediment stability and water clarity. Coastal seagrass meadows are therefore an important resource economically and ecologically. Information on the species composition, abundance and distribution of seagrasses is used by management to zone for protection of seagrass habitats
