Phosphate dosing of drinking water supplies, coupled with leakage from distribution networks, represents a significant input of phosphorus to the environment. The oxygen isotope composition of phosphate (δ(18)OPO4), a novel stable isotope tracer for phosphorus, offers new opportunities to understand the importance of phosphorus derived from sources such as drinking water. We report the first as...

Introduction: The low effective mass and higher mobility of carriers in germanium (Ge) compared to silicon (Si) (two times higher mobility for electrons and four times for holes) has prompted renewed interest in Ge-based devices for high-performance logic, especially as it becomes increasingly difficult to enhance Si CMOS performance through traditional device scaling. However, it has been diff...

Work from this laboratory has established that brain cephalin (1, 2) is a mixture of three different phosphatides; namely, phosphatidyl serine (3), phosphatidyl ethanolamine, and diphosphoinositide. In a preliminary note (4) it has been shown that diphosphoinositide has inositol metadiphosphate’ as a constituent. The present paper contains detailed proof of this statement and reports some other...

Water reuse through greywater irrigation has been adopted worldwide and has been proposed as a potential sustainable solution to increased water demands. Despite widespread adoption, there is limited domestic knowledge of greywater reuse. There is no pressure to produce low-level phosphorus products and current guidelines and legislation, such as those in Australia, may be inadequate due to the...

This study examined the utilization of potato processing wastewater as the feedstock by two oleaginous fungi, Aspergillus flavus I16-3 and Mucor rouxii, for lipid and gamma linolenic acid production. The high strength wastewater contained soluble carbohydrates of 36.2 g/l, soluble chemical oxygen demand (COD) of 40 g/l, total soluble nitrogen of 0.62 g/l, and soluble total phosphorus of 0.24 g/...

BACKGROUND, AIM, AND SCOPE Recent assessments of water quality status have identified eutrophication as one of the major causes of water quality 'impairment' not only in the USA but also around the world. In most cases, eutrophication has accelerated by increased inputs of phosphorus due to intensification of crop and animal production systems since the early 1990 s. Despite substantial measure...
