“ Hydro Maintenance Re - engineering within the Snowy Mountains Scheme ”
The Snowy Mountains Hydro-electric Authority has recently undertaken a program of analysing the routine maintenance completed on its main generation and hydraulic assets. Power industry deregulation and increasing competition have created the need to reduce costs while increasing productivity. Along with downsizing and organisational restructuring, considerable effort has been placed on improvi...
متن کاملMetallogeny of Eocene Syncollisional Granites of Motajica and Prosara Mountains
The geological setting is dominated by Eocene (48.7 Ma) syncollisional granitoids in the form of a small pluton in the Motajica Mt. and in the form of numerous sills and dykes in the Prosara Mt. Microelement paragenesis of these magmatites, pegmatites, greisens and quartz veins are distinguished by U, Th, Ce, Y, P, Nb, Ta, B, Li, F, Be, Sn, Mo, W, Fe, Cu, Pb. These elements and 87Sr/86Sr and δ1...
متن کاملAn artificial trend in District Average Rainfall in the Snowy Mountains
A strong decline is apparent in annual District Average Rainfall (DAR) for District 71, located in the Snowy Mountains of New South Wales (Fig. 1). There has been some concern that this decline of about 200 mm, i.e. about 20 per cent, since 1913 could be the result of human interference with the environment, and that a continuing decline in rainfall could threaten ecosystems and irrigation. The...
متن کاملNatural radioactivity in granites and gneisses of the Opava Mountains (Poland): a comparison between laboratory and in situ measurements
The natural radioactivities of five characteristic igneous rocks of the eastern foreland of the Opava Mountains (Eastern Sudetes, Poland), obtained in the laboratory and under in situ conditions, are presented. The activity concentrations of 232Th, 238U, and 40K were measured using an HPGe gamma-ray spectrometry system. The ranges of the activity concentrations of 232Th were 7-71 Bq kg-1 in the...
متن کاملSnowy Owl Predation on Short-eared Owls
A problem confronting Snowy Owls (Nyctea scandiaca) in their southern incursions is the shortage of food. This difficulty is raised by the presence of other raptors that feed on small mammals. This note shows how little food is found by migrant Snowy Owls and indicates a complex temporary ecological solution. At Tatoosh Island, Washington (48”24’ N, 124” 44’ W) on 25 November 1973, we observed ...
