Amphibians are currently suffering a period of mass extinction with approximately 20% of species under severe threat and more than 120 species already extinct. In light of this crisis there is an urgency to establish viable ex situ populations and also find the causes of in situ declines. The role of ultraviolet radiation and Vitamin D(3) in amphibian health directly influences both ex situ and...

Australia is rich in orchid flora with over 1000 native species currently recorded. A significant proportion of Australia’s terrestrial orchids are critically endangered, endangered or threatened. Threats to many orchid species include habitat destruction, degradation and fragmentation from increased urbanisation, overgrazing, altered fire regimes and unfortunately, excessive collecting by orch...

This thesis consists of uncertainty and techno-economic studies of two different biofuels production pathways (catalytic pyrolysis and gasification). The objective of this paper is to obtain a side-by-side techno-economic comparison of in situ and ex situ catalytic pyrolysis, and gasification state-of-technology and target scenarios that addresses both sensitivity and uncertainty analysis in th...

To what extent do people achieve accuracy in judging others’ situations? Based on interpersonal perception models, we propose that ex-situ raters may attain accuracy by judging the psychological characteristics of a situation that in-situ raters have experienced according to a normative and distinctive characteristics profile. Biesanz’ Social Accuracy Model (SAM) provides a flexible crossed-eff...

The changes in the surface phase and the morphology of nickel–yttria stabilized zirconia (YSZ) cermet anodes for solid oxide fuel cells (SOFCs) upon exposure to a fuel containing 100 parts per million (ppm)-level hydrogen sulfide (H2S) at elevated temperatures were investigated using in situ Raman microspectroscopy as well as ex situ techniques such as X-ray diffraction (XRD), scanning electron...

Biochar contains quinones and aromatic structures that facilitate extracellular electron transfer between microbial cells and insoluble minerals. In this study, granulated biochar (1.2-2 mm) and powdered biochar (<0.15 mm) were amended to two ferrihydrite (in situ ferrihydrite and ex situ ferrihydrite) enrichments to investigate the effect of biochar with different particle sizes on dissimilato...

The paper is a short review on the soil decontamination applying ex-situ techniques. Some sources and pathways of soil contamination are discussed. It was revealed that available techniques for soil decontamination can be divided in two parts, depending on where the action have place: in-situ or ex-situ. Also, depending on the nature of the process, these techniques can be biological, physical-...

PURPOSE To establish a method for assessing graft viability, in-vivo, following corneal transplantation. METHODS Optimization of calcein AM fluorescence and toxicity assessment was performed in cultured human corneal endothelial cells and ex-vivo corneal tissue. Descemet membrane endothelial keratoplasty grafts were incubated with calcein AM and imaged pre and post preparation, and in-situ af...
