Cavitation erosion : the effect of fluid and flow parameters
This thesis describes an investigation into the effect of fluid and flow parameters on
cavitation dynamics and cavitation erosion. A rotating disc test apparatus was developed
fo: dow-type cavitation studies. A vibratory test device was also developed to study the
role of cathodic and anodic potentials applied to cavitating bodies. Some major results
are given below.
Erosion "peaksat about 50°C in water, but under certain conditions material degradation
caused by increased corrosion rate cancels out thermodynamic effects at higher
temperatures. An erosion peak is also observed as a function of static pressure. Damage
increases with velocity until cavitation is fully developed, at which stage the influence of
velocity becomes negligible. The changes in erosion zone geometry and mass loss caused
by temperature, velocity and pressure variations may be correlated with the effect these
parameters have on the cavitation pressure profile. Efforts are described to develop a
system for measuring this profile in the rotating disc device.
Water quality including dissolved ions, as well as solid and gas impurities, influences both
cavitation inception and the amount of cavitation damage caused. The synergism
between cavitation erosion and corrosion causes high damage rates in corrosive,
cavitating liquids. Solid impurities at medium concentrations may enhance or retard
cavitation damage substantially, depending on the physical properties of the solid. Below
the saturation level, increasing concentration of dissolved air in water results in a slight
decrease in damage, but damage can be almost completely eliminated by the release of
air bubbles into the cavitation region.
Another important result is that the gas developed by the application of external
potentials to a cavitating body provides protection against cavitation erosion through a
gas cushioning mechanism. Cathodic protection of cavitating bodies will thus serve to
decrease damage rates even in the case of corrosion-resistant materials like stainlessGR 201
Electronic properties of E3 electron trap in n-type ZnO
International audienceDeep level transient spectroscopy measurements were per- formed on three non-intentionally doped n-type ZnO samples grown by different techniques in order to investigate the electronic properties of E3 electron trap. The ionization energy and the capture cross-section are found respectively at 0.275 eV from the conduction band and 2.3×10^−16 cm2 with no electric field dependence. This center is present irrespective of the synthesis method. In view of its physical properties and recent works published in the literature, its physical origin is discussed. Based mainly on its insensibility to the macroscopic electric field, the best candidates turn out to be dual defects with opposite charges on adjacent sites, like the dual vacancy VO -VZn
Book-to-market ratio and returns on the JSE
Many firm-specific attributes or characteristics are
understood to be proxies for what Fama and French
(1992: p428) refer to as “the unnamed sources of risk”.
Perhaps the most notorious of these is the size of the
firm or its market value, first documented by Banz
(1981). The relationship between size and average
returns has become known as the “size effect”.KIM201
Participatory social auditing : a practical guide to developing a gender-sensitive approach
A participatory approach to codes of labour practice comes from a different perspective to more
compliance focused snapshot social auditing. It puts greater emphasis on involvement of workers and
workers organisations in the process of code implementation and assessment. It is based on developing
partnerships between different actors (companies, trade unions, NGOs and preferably government) in
developing a locally sustainable approach to the improvement of working conditions. This approach is
sensitive to uncovering and thus addressing more complex issues such as gender discrimination and sexual
harassment. These are issues more likely to be experienced by insecure non-permanent workers, who are
often women, whose voices snapshot audits usually fail to pick up. They are less visible issues, that
are unlikely to be resolved through a simple compliance approach. The goal of a participatory approach is
a process of awareness creation and improvement that is more gender sensitive.
A participatory approach can be developed at different levels. At a minimum it involves the use of
participatory tools in the process of social auditing to ensure that the views and voices of workers,
especially women workers, are captured in an audit. More genuine participation by workers also requires
the involvement of workers representatives or shop stewards at site level, and sector trade unions and
NGOs, both in awareness creation and auditing process. At its broadest level, it involves the development
of local multi-stakeholder initiatives that bring companies, trade unions and NGOs together with
government in forming an independent body able to oversee the implementation, and monitoring of a
locally relevant code of labour practice. Such an approach faces many challenges, but it represents a shift
away from a formal top down compliance orientation, to the greater empowerment of workers and their
representative organisations as an essential part of the process of improving labour standards and working
conditions.
This paper is aimed primarily at policymakers and practitioners with a practical interest in developing
a gender-sensitive approach to participatory social auditing and codes of labour practice.

A comparative analysis of returns of various financial asset classes in South Africa: a triumph of bonds?
There is a popular view that equities always outperform other fi nancial asset classes; especially bonds. This study investigates the performance of three common asset classes to determine whether or not this view is validated in South Africa. Conceptually, the popular view is irrational. If one class consistently and materially outperforms other asset classes, in the absence of other reasons, the other asset classes would disappear. Accordingly, rationally, in the long run and on a risk-adjusted basis, returns on all asset classes should conceptually more or less converge. The results from this study, which concentrates on equities, bonds and cash, show that in South Africa, even before adjusting for risk, there was no material difference between the returns of equities over long bonds over the 27-year period covered by this study (1986–2013). This is equally true for other shorter fi xed periods with the end-date (28 February 2013) being the focal point. It is even more evident that bonds outperform equities when a system of rolling periods is used. On a nominal basis (before adjusting for risk), over any randomly selected rolling period, bonds outperform equities in six of the seven categories. This study does not take tax into consideration. After adjusting for risk using the Sharpe ratio or other risk measures, bonds outperformed equities.Key words: equities, bonds, cash, performance, asset classes, risk-adjusted basis, outperformanc
