Environmental reporting

The research reported herein has demonstrated that pervious pavements can be introduced as a sustainable stormwater management initiative and as a key Water Sensitive Urban Design feature to deliver numerous benefits to the environment. The outcomes from the study will be useful in designing environmentally friendly car parks, pedestrian paths, light traffic drive ways, sporting grounds and public areas in the future.

This thesis explores the problem of wasteful fashion consumption in light of the current need for individuals to develop a sustainable way of living. The Agenda 21 report from the Rio Earth Summit (1992) determined that sustainable consumption is an issue to be addressed in terms of resource conservation, waste reduction and a reduction of production pollutants. To date, in Australia, there are no policies or strategies in place to reduce wasteful consumption from the consumer’s perspective and it is this research and policy deficit that this thesis research addresses.

This thesis examines the strategic and potentially legitimising nature of voluntary environmental reporting. First, the thesis examines the relationship between emission levels on the National Pollutant Inventory and the quantity of total voluntary environmental disclosures, voluntary emission disclosures and positive voluntary environmental disclosures in annual reports. Second, an examination of changes in the quantity of disclosures discussing compliance with the National Pollutant Inventory and/or disclosures concerning pollution emissions is undertaken.

This research is comprised of three interrelated stages of a broader study of the climate change-related corporate governance disclosure practices of Australian companies. The first stage of the study investigates the climate change-related corporate governance disclosure practices of five major Australian energy-intensive companies over a 16-year period (from 1992 to 2007). The five companies are BHP Billiton, Caltex, Origin Energy, Rio Tinto and Santos Limited.

The research "Social and environmental reporting practices of the gambling industry: an Australian perspective" explores the corporate social and environmental disclosure (CSD) practices of Australian gambling companies to understand what information is reported in CSDs, and why. The first part of the study performs an analysis of the two gambling companies; annual reports (1995-2009) to investigate the changing trend of the CSDs.

Soil erosion strongly affects crop yield, undermines the long term productivity of farm land and sustainability of farming system, and poses a major threat to the livelihood of the farmers and rural communities. The United Nations Environmental Program reported that the productivity of soil has reduced and resulting in economically unfeasible cultivation on about 20 million hectare of land each year due to soil erosion and resulting degradation of land.

The K103N substitution is a frequently observed HIV-1 RT mutation in patients who do not respond to combinationtherapy. The drugs Efavirenz, MSC194 and PNU142721 belong to the recent generation of NNRTIs characterized by an improved resistance profile to the most common single point mutations within HIV-1 RT, including the K103N mutation. In the present study we present structural observations from Efavirenz in complex with wild-type protein and the K103N mutant and PNU142721 and MSC194 in complex with the K103N mutant.

Trehalose metabolism is an essential component of the stress response in yeast cells. In this work we show that the products of the principal genes involved in trehalose metabolism in Schizosaccharomyces pombe, tps1+ (coding for trehalose6-P synthase, Tps1p), ntp1+ (encoding neutral trehalase, Ntp1p) and tpp1+ (that codes for trehalose-6-P phosphatase, Tpp1p), interact in vitro with each other and with themselves to form protein complexes. Disruption of the gene tps1+ blocks the activation of the neutral trehalase induced by heat shock but not by osmotic stress.

Starch defines a semicrystalline polymer made of two different polysaccharide fractions. The A- and B-type crystalline lattices define the distinct structures reported in cereal and tuber starches, respectively. Amylopectin, the major fraction of starch, is thought to be chiefly responsible for this semicrystalline organization while amylose is generally considered as an amorphous polymer with little or no impact on the overall crystalline organization.

Many biological C-H activation reactions exhibit nonclassical kinetic isotope effects (KIEs). These nonclassical KIEs are too large (kH/kD 7) and/or exhibit unusual temperature dependence such that the Arrhenius prefactor KIEs (AH/AD) fall outside of the semiclassical range near unity. The focus of this minireview is to discuss such KIEs within the context of the environmentally coupled hydrogen tunneling model.

Recent years have witnessed high levels of activity in identifying enzyme systems that catalyse H-transfer by quantum tunneling. Rather than being restricted to a small number of specific enzymes as perceived initially, it has now become an accepted mechanism for H-transfer in a growing number of enzymes. Furthermore, H-tunneling is driven by the thermally induced dynamics of the enzyme. In some of those enzymes that break stable C–H bonds the reaction proceeds purely by quantum tunneling, without the need to partially ascend the barrier.

The structure of the O-polysaccharide of the lipopolysaccharide from a diarrheal strain isolated in Bangladesh was studied with sugar, and methylation analysis, NMR spectroscopy, mass spectrometry and partial acid hydrolysis. The strain was first designated as Hafnia alvei, but later found to be a possible new species in the genus Escherichia. Two different polysaccharides were detected, a major and a minor one. The structure of the major polysaccharide is given below, while the structure of the minor one was not investigated. ...

The expression of mitochondrial and hydrogenosomal ADP/ATP carriers (AACs) from plants, rat and the anaerobic chytridiomycete fungus Neocallimastix spec. L2 in Escherichia coli allows a functional integration of the recombinant proteins into the bacterial cytoplasmic membrane. For AAC1 and AAC2 from rat, apparent Km values of about 40 lM for ADP, and 105 lM or 140 lM, respectively, for ATP have been determined, similar to the data reported for isolated rat mitochondria.

Mikrobiologisches Institut der Eidgeno¨ssischen Technischen Hochschule, ETH-Zentrum, Zu¨rich, Switzerland The membrane-bound b subunit of the oxaloacetate decarboxylase Na+ pump of Klebsiella pneumoniae catalyzes the decarboxylation of enzyme-bound biotin. This event is coupled to the transport of 2 Na+ ions into the periplasm and consumes a periplasmically derived proton. The connecting fragment IIIa and transmembrane helices IV and VIII of the b subunit are highly conserved, harboring residues D203, Y229, N373, G377, S382, and R389 that play a profound role in catalysis. ...

There is extensive evidence that FcR c-chain couples to the collagen receptor glycoprotein VI (GPVI) and becomes phosphorylated on tyrosines upon receptor cross-linking. However, it is not established whether this receptor complex is sufficient to initiate the signalling cascade. We transfected GPVI and the FcR c-chain into the human erythroleukaemia cell line K562, which lacks detectable expression of GPVI and the FcR c-chain. The results show that GPVI is unable to signal when expressed alone, despite its surface expression, upon stimulation with the snake C-type lectin, convulxin....

Human glandular kallikrein 2 (hK2) is a trypsin-like serine protease expressed predominantly in the prostate epithelium. Recently, hK2 has proven to be a useful marker that can be used in combination with prostate specific antigen for screening and diagnosis of prostate cancer. The cleavage by hK2 of certain substrates in the proteolytic cascade suggest that the kallikrein may be involved in prostate cancer development; however, there has been very little other progress toward its biochemical characterization or elucidation of its true physiological role.

VanXYC, a bifunctional enzyme from VanC-phenotype Enterococcus gallinarum BM4174 that catalyses D,D-peptidase and D,D-carboxypeptidase activities, was purified as the native protein, as a maltose-binding protein fusion and with an N-terminal tag containing six histidine residues. The kinetic parameters of His6–VanXYC were measured for a variety of precursors of peptidoglycan synthesis involved in resistance: for D-Ala-D-Ala, the Km was 3.6 mM and kcat, 2.5 s)1; for UDP-MurNAc-L-Ala-D-Glu-L-Lys-D-Ala-DAla (UDP-MurNAc-pentapeptide[Ala]), Km was 18.8 mM and kcat 6.
