The University of Adelaide is a public university in Adelaide, South Australia. Established in 1874, it is the third oldest university in Australia. It is associated with five Nobel laureates, 104 Rhodes scholars and is a member of the Group of Eight, as well as the sandstone universities.Its main campus is on North Terrace in the Adelaide city centre, adjacent to the Art Gallery of South Australia, the South Australian Museum and the State Library of South Australia. The university has five campuses throughout the state: North Terrace; Roseworthy College at Roseworthy; The Waite Institute at Urrbrae; Thebarton; and the National Wine Centre in the Adelaide Park Lands. It has a sixth campus, the Ngee Ann – Adelaide Education Centre , in Singapore.The 20th Vice-Chancellor of the University is Professor Warren Bebbington. Formerly Deputy Vice-Chancellor at the University of Melbourne, he commenced in July 2012. Wikipedia.

This paper presents results of an experimental study on the behavior of square and rectangular high-strength concrete (HSC)-filled fiber-reinforced polymer (FRP) tubes (HSCFFT) under concentric compression. The effects of the tube thickness, sectional aspect ratio, and corner radius on the axial compressive behavior of concrete-filled FRP tubes (CFFT) were investigated experimentally through the tests of 24 CFFTs that were manufactured using unidirectional carbon fiber sheets and high-strength concrete with 78 MPa average compressive strength. As the first experimental investigation on the axial compressive behavior of square and rectangular HSCFFTs, the results of the study reported in this paper allow a number of significant conclusions to be drawn. First and foremost, test results indicate that sufficiently confined square and rectangular HSCFFTs can exhibit highly ductile behavior. The results also indicate that confinement effectiveness of FRP tubes increases with an increase in corner radius and decreases with an increase in sectional aspect ratio. It is also observed and discussed that HSCFFTs having tubes of low confinement effectiveness may experience a significant strength loss at the point of transition on their stress-strain curves. Furthermore, it is found that the behavior of HSCFFTs at this region differ from that of normal-strength CFFTs and that it is more sensitive to the effectiveness of a confining tube. Examination of the test results have also lead to a number of important observations on the influence of the key confinement parameters on the development and distribution of the hoop strains on the tubes of CFFTs, which are presented and discussed in the paper. © 2013 American Society of Civil Engineers.

Bridging ligands incorporating 2,2'-bipyridine as a chelating component have been utilised for several decades and are widely employed in coordination chemistry, supramolecular chemistry and materials synthesis. Such ligands form stable 5-membered chelate rings upon coordination to a metal. Two related chelating units, di-2-pyridylamine and di-2-pyridylmethane, which form 6-membered chelate rings when coordinated to a metal, have been studied far less as components of bridging ligands but have recently garnered significant levels of attention. Of around 140 reports on the incorporation of these moieties into bridging ligands some 75% have been published in the last 15 years. This review covers the synthesis of bridging ligands containing di-2-pyridylamine and di-2-pyridylmethane chelating moieties, and a survey of their coordination and supramolecular chemistry. Applications of the resulting systems as structural and functional models of enzyme active sites, and spin-crossover materials, and for investigations into anion-π interactions are covered. © 2011 Elsevier B.V.

A comprehensive experimental program has been underway at the Structures Laboratory of the University of Adelaide to investigate the behavior of concrete-filled fiber-reinforced polymer (FRP) tubes (CFFTs) under concentric compression. This paper presents the results from a group of 92 selected circular, square, and rectangular CFFTs and discusses the influence of the critical column parameters on the compressive behavior of CFFTs. These parameters include concrete strength, amount and type of FRP tube material, manufacture method of the tubes, and size and shape of the CFFTs. In addition to conventional FRP tubes, new types of tubes with integrated internal FRP reinforcement have been designed and tested. Results indicate that concrete strength, cross-sectional shape, and the amount and type of tube material significantly affect the behavior of CFFTs. The manufacture method of FRP tube also has some, but less significant, influence on the behavior of CFFTs. The influence of specimen size has been found to be small. No apparent difference has been found between the compressive behaviors of circular CFFTs and companion FRP-wrapped cylinders. The results also indicate that newly developed square and rectangular CFFTs, with internal FRP reinforcement, exhibit significantly improved behavior over conventional CFFTs. © 2013 Elsevier Ltd.

Depending on the method of NaCl application, whether gradual or in a single step, plants may experience either salt stress or salt shock, respectively. The first phase of salt stress is osmotic stress. However, in the event of salt shock, plants suffer osmotic shock, leading to cell plasmolysis and leakage of osmolytes, phenomena that do not occur with osmotic stress. Patterns of gene expression are different in response to salt stress and salt shock. Salt stress initiates relatively smooth changes in gene expression in response to osmotic stress and a more pronounced change in expression of significant numbers of genes related to the ionic phase of salt stress. There is a considerable time delay between changes in expression of genes related to the osmotic and ionic phases of salt stress. In contrast, osmotic shock results in strong, rapid changes in the expression of genes with osmotic function, and fewer changes in ionic-responsive genes that occur earlier. There are very few studies in which the effects of salt stress and salt shock are described in parallel experiments. However, the patterns of changes in gene expression observed in these studies are consistently as described above, despite the use of diverse plant species. It is concluded that gene expression profiles are very different depending the method of salt application. Imposition of salt stress by gradual exposure to NaCl rather than salt shock with a single application of a high concentration of NaCl is recommended for genetic and molecular studies, because this more closely reflects natural incidences of salinity. © 2012 The Author.

The human senses have always been used to assess food quality. Although the senses of sight, hearing, taste, smell, and touch are used daily in all aspects of our lives, their analytical applications to evaluate food properties are relatively recent. The sensory systems of Homo sapiens are the product of millions of years of evolution where natural selection has resulted in our capacity to detect a wide range of compounds present in the environment, advantageous to our survival, allowing hedonistic evaluation of the environment. Existing analytical methods used to measure wine and alcoholic beverages composition and quality are not adequate for the demands of production in a global market due to their high cost and slow turnaround time. In the last 20 years increasing interest on the use of rapid screening techniques or instrumental methods to determine quality characteristics of foods and beverages has been of great interest to the food industry.
