The research titled "A study of the Lithgow New Government Office Development: using best practice to deliver sustainable developments" is based on the hypothesis that applying building industry’s best practice initiatives can deliver sustainability within the built environment. This hypothesis assumes links between the applied practices, the outcome achieved and sustainability.

This research is based on the hypothesis that applying building industry’s best practice initiatives can deliver sustainability within the built environment. This hypothesis assumes links between the applied practices, the outcome achieved and sustainability. This research tests this hypothesis with a single ‘critical’ case project; the recently constructed Lithgow Government Office Building (GOB) Development, and against a theoretical framework that defines sustainability.

In order to further test the hypothesis, this paper will first present a history of globalization in China as well as research on income inequality before the creation of the Open Door Policy. Second, research will be conducted on the impact of globalization in China post Open Door Policy using multinationals as case studies. The research results will provide evidence that the process of globalization led by the economic reform has changed the Chinese economy outlook, and caused income inequality comparing to how it was before the economic reform.

Hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) are the most common hereditary cardiac conditions. Both are frequent causes of sudden death and are often associated with an adverse disease course.Alpha-cardiac actinis one of the disease genes where different mis-sense mutations have been found to cause either HCM or DCM. We have tested the hypothesis that the protein-folding pathway plays a role in dis-ease development for two actin variants associated with DCM and six asso-ciated with HCM....

The positive cofactor 4 (PC4) protein has an important role in transcrip-tional activation, which has been proposed to be mediated by transcription factor IIA (TFIIA) and TATA-binding protein-associated factors. To test this hypothesis, we cloned the Schizosaccharomyces pombe PC4gene and analysed the role of the PC4 protein in the stimulation of basal tran-scription driven by TATA-containing and TATA-less promoters.

The hypothesis is tested that Jun–Fos activator protein-1 coiled coil inter-actions are dominated during late folding events by the formation of intri-cate intermolecular electrostatic contacts. A previously derived cJun–FosW was used as a template as it is a highly stable relative of the wild-type cJun–cFos coiled coil protein (thermal melting temperature = 63C versus 16C), allowing kinetic folding data to be readily extracted.
