The Extraction of Manganese from Manganese Flue Dust.

It is estimated that 90 to 95% of the world’s consumption of manganese is used in the steel industry in the form of either ferromanganese or spiegeleisen. The remainder is used in the form of either salts or oxides, chloride, dioxide and monoxide.

Investigation of a Method for Extraction of Indium from Zinc Flue Dust.

In metallurgical practice today some of the relatively rare metal Indium is recovered as a by-product from the ores of other metals. Indium is a soft, silvery—white metal belonging to the third group of the periodic classification. It is situated just above tin in the electrochemical series.

An Investigation of the Precipitation of Cobalt with Zinc Dust

Cobalt, as well as copper, cadmium, and other impurities, is removed by selective precipitation with zinc during the zinc electrolyte purification cycle, and the purification residue may be treated by a Cadmium Plant for the recovery of cadmium.

Street Children and Mobile Youth Work in Africa - the 8th ISMO Symposium October 2003

The International Society for Mobile Youth Work (ISMO) and the National Council of Churches in Kenya (NCCK) organised from the 27th to 30th October 2003 at the Jumuia Conference and Country Home in Limuru/Kenya with 198 participants from 35 countries around the world the 8th International Symposium on Mobile Youth Work with special focus on children at risk (street children and youth) in Africa. For this purpose there were invited field workers, scientists and stakeholders engaged as advocates for the rights and well being of endangered children and youths. The participants came mainly from African countries and of course especially from Kenya, but also from Asia, Latin America and from Europe.

The Active Subjects of Welfare Reform: a Street-Level Comparison of Employment Services in Australia and Denmark

This paper explores the similarities and differences between Denmark and Australia in adopting welfare reform activation measures in the field of employment services. In Australia and Denmark the discourse of welfare reform centres the 'activation' of citizens through 'mutual obligation' type requirements. Through various forms of case management, unemployed individuals are encouraged to act upon themselves in creating the right set of ethical dispositions congruent with 'active citizenship'. At the same time any resistance to heightened conditionality on the part of the unemployed person is dealt with through a range of coercive and disciplinary techniques. A comparative case study between these two countries allows us to consider how similar ideas, discourse and principles are shaping policy implementation in countries that have very different welfare state trajectories and institutional arrangements for the delivery of social welfare generally and employment services specifically. And in research terms, a comparison between a Nordic welfare state and an Anglo-Saxon welfare state provides an opportunity to critically examine the utility of 'welfare regime' type analyses and the neo-liberal convergence thesis in comparative welfare research. On the basis of empirical analysis, the article concludes that a single focus on abstract typologies or political ideologies is not very helpful in getting the measure of welfare reform (or any other major policy development for that matter). At the 'street-level' of policy practice there is considerably more ambiguity, incoherence and contradiction than is suggested by linear accounts of welfare reform.
