Magnesium-zinc reduction is effective in preparation of metals

Uranium, thorium, and plutonium are effectively prepared by magnesium-zinc reduction, using uranium oxides, thorium dioxide, and plutonium dioxide as starting materials. This technique is also useful in performing reduction of metals such as zirconium and titanium

The hydrological impact of the Parangana Dam on the Mersey River, Tasmania

By diverting the waters of the Mersey River into a neighbouring basin, the Parangana Darn changed the hydrological character of the downstream river. The flow records of three gauging stations, located at 10, 67 and 88 km below the dam, provide the basis for identifying changes. Intermediate discharges have decreased the most and even at the furthest downstream station are 50% lower than before. The flow extremes, at both ends of the scale, have been less affected, and particularly the less frequent discharges which can be augmented by overspill. Indeed the highest flood on record, with a recurrence interval of over 500 years, occurred in the post-dam period. One-day and 30-day minimum flows are markedly lower downstream of the dam, but below the Dasher, the main tributary of the Mersey, they seem to recover and have almost regained pre-dam levels by the mouth. The entry of unregulated tributaries in the middle section separates a much changed upstream hydrology from a downstream one able to mitigate the worst effects of the dam except at intermediate discharges. In the upstream part, the physical, chemical and biological character of the river could be adversely affected by the altered flow regime, particularly in those reaches immediately below the dam

Chiasmatic Narrative and Twisted Subjectivity in Kanai Mieko's Boshizô

The article provides a reading, from a psychoanalytic point of view, of Japanese writer Kanai Mieko's short tale Boshizô (Portrait of Mother and Child), published in 1992, as a "twisted" or "contorted" parable of the construction of female subjectivity. Establishing connections between the form and the content of the novel, the essay analyzes how Kanai's use of the rhetorical figure of the chiasmus structures the internal narrative of the novel at the same time that it reflects the process of formation of female subjectivity and desire. The novel becomes, thus, a staging of the female Oedipus complex which plays out its twists

Streamflow characteristics of northeastern Tasmania: I. regional flood flows

Based on streamflow records from thirteen stations, regional equations are developed which enable the estimation of mean annual discharge and various flood flows at ungauged sites along rivers in northeastern Tasmania. The area around Swansea is shown to be hydrologically distinct, at least as far as flood discharges are concerned, and the analysis subsequently focuses on the rest of the region. Despite the wide range of climatic and physiographic conditions there, relationships are highly significant, with drainage area explaining more than 97% of the variation in flood discharge. Rates of change are not only relatively high but increase with flood magnitude, suggesting rapid downstream transmission of flood waters. Network magnitude may be a viable alternative to drainage area as an estimator. Its use has the advantage that the downstream pattern of flow addition can be readily charted for major rivers, as illustrated for the Ringarooma and George

Streamflow characteristics of northeastern Tasmania: II. Hydraulic geometry

Relationships describing the adjustment of water-surface width, mean depth and mean velocity to increasing discharge are calculated for eleven sections in northeastern Tasmania. The at-a-station graphs of two sections display distinct discontinuities related, however, to different causes - sub-bankfull channelization and the attainment of overbank stage. Despite intra-reach and inter-fluvial variations in hydraulic geometry, two types of response seem to be dominant, characterised by a high rate of change of either depth or velocity. Two sections do not fit into this pattern and, significantly, they tend to plot poorly on downstream graphs. Bankfull discharge probably lies between Q1.11 and Q2 at most sites, so both flows are used as reference discharges in analyses of downstream adjustment at the regional scale. The relations at Ql.ll and Q2 are quite similar and they are within the envelope defined by results from other areas. However, the data base is small and the scatter is large enough to render the velocity-discharge relation non-significant. The main residual from regression is the station on the South Esk at Perth which is used for discharge measurements at higher flows. Nevertheless, the hydraulic geometry equations enable estimates to be made of channel flow properties at ungauged sites within the northeastern river system

Applying Total Quality Leadership to an aviation squadron

The implementation of Total Quality Leadership has been successful in several Department of Defense organizations. However, an aviation squadron provides an unique environment for the application of TQL. This thesis describes an adaptation of the NPRDC TQM process improvement model for a fleet squadron which includes the Shewart Cycle, customer supplier relationships, and mission deployment. Dr. W. Edwards Deming's 14 points are discussed in the context of the squadron environment. Continuous process improvement tools are explained and demonstrated using squadron examples.http://archive.org/details/applyingtotalqua00knigLieutenant Commander, United States NavyLieutenant, United States NavyApproved for public release; distribution is unlimited
