I am very pleased to have been invited by Tim Murray, the President of the South African Sugar Technologists’ Association, to be the keynote speaker for this year’s SASTA Congress. I am particularly pleased to have been invited this year because BSES is celebrating its centenary and, in September 2001, Australia will be hosting the ‘new look’ 24th Congress of the International Society of Sugar ...

Previous studies have shown a rapid enhancement in leaf hydraulic conductance (K(leaf)) from low to high irradiance (from <10 to >1000 micromol photons m(-2) s(-1)), using the high-pressure flow meter (HPFM), for 7 of 14 tested woody species. However, theoretical suggestions have been made that this response might arise as an artifact of the HPFM. We tested the K(leaf) light response for six ev...

it is widely believed that pain has a profound effect on health related quality of life. this study was conducted to assess quality of life in patients suffering from different density of chronic low back pain. the sample consisted of 101 patients with chronic low back pain attending to the rheumatology research center of tehran university of medical sciences between july and september 2003. al...

We determined effects of venation traits on hydraulic conductance of phyllodes (foliage), using an array of Acacia s.str. species with diverse phyllode morphologies as the source of variation. Measurements were made on phyllodes from 44 species, grown in common gardens but originating from different positions along a precipitation gradient. K(phyllode) varied 18-fold and was positively correla...

BACKGROUND Atypical bovine spongiform encephalopathies (BSEs) are recently recognized prion diseases of cattle. Atypical BSEs are rare; approximately 30 cases have been identified worldwide. We tested prion gene (PRNP) haplotypes for an association with atypical BSE. METHODOLOGY/PRINCIPLE FINDINGS Haplotype tagging polymorphisms that characterize PRNP haplotypes from the promoter region throu...

Technology is important because of the high cost of obtaining fermentable sugars efficiently from cellulosic biomass. Many microorganisms capable of producing cellulose and hemicellulose-degrading enzymes have been reported and characterized. Currently, fungal cellulases are prepared and utilized to saccharify cellulosic biomass. It is known that the fungus Trichoderma reesei is able to produce...

Le lait maternel est reconnu comme aliment idéal pour les nouveau-nés, y compris prématurés, avec des avantages nutritionnels, biologiques, émotionnels et socio-économiques l’enfant la famille. Pour bébés l’allaitement joue un rôle essentiel dans mesure où il associé à une réduction du temps d’hospitalisation divers états cliniques résultant d’une prématurité. Les études indiquent faible taux d...

Since 1995 (the last time the author addressed the SASTA Congress), the Australian sugar industry has been through significant change. This paper discusses some of those changes and provides a perspective on the responses to those changes. The industry has been through both good and bad times in this period. Production, price and profitability have been through the familiar cycle of highs and l...

This study set out to evaluate the wound healing properties of brittle star extracts in vitro and vivo. Due great arm regeneration potential star, Ophiocoma cynthiae, present aimed effect hydroalcoholic undergoing models. The samples were collected from Nayband Bay, Bushehr, Iran. After induction stars, relating different times prepared. GC-MS analysis, MTT cell viability migration, Western blo...
