A study on the slag dispersion in bath smelting converter was undertaken. The aim was mainly to investigate the behaviour of the dispersed slag phase at high gas flow rate and low slag volume (10%) systems. For simulations purposes, water; paraffinoil and air were used in a one fifth model of the commercial 100 ton Creusot-Loire- Uddeholm converter to represent bulk steel, molten slag and gas respectively. Emulsion samples were collected by means of the specially made syringe. The experimental results revealed that the dispersed slag phase decreased with the vertical distance from the original interface between the liquid phases. The dispersed phase decreased also with the radial distance in the water plume zone towards the wall side. The holdup was apparently much observable on the right side than on the left side. Four dimensionless numbers defined the dispersion phenomenon through the dimensional analysis. The modified Froude Number ensured the correlation between both model and prototype. The standard error of the estimate and R-squared between the experimental and the calculated results were 3.7 ´10-4 and 0.97 respectively.

Exploring two hotly contested issues, corporate social responsibility (CSR) and the extractive industries, this report will demonstrate to a general reading audience the necessity of CSR as a business practice. The report finds that, given pressures from globalization and stakeholders, CSR is no longer an optional practice in the extractive industries but a business imperative. In general, why is CSR an important practice for businesses to adopt? In the extractive industries, what distinguishing CSR issues do they face, and how is CSR being propelled forwards in these industries? This report explores these questions and offers recommendations for policymakers and extractive companies on how to ensure CSR is implemented in a way that meets society’s great expectations. / text

This thesis offers an investigation of the indigenous politics of self-determination in the Peruvian Amazon. The starting point of the analysis is the ‘Baguazo’, a massive indigenous protest (June 2009) against governmental laws that favoured extractive industries within indigenous territories. Studies of indigenous peoples’ opposition to extractive industries in Peru have tended to focus on the economic, political or social aspects as if these were discrete dimensions of the conflict. This thesis aims to contribute with an integral and systematic understanding of indigenous resistance to extractive industries through a case study analysis and a multidisciplinary theoretical proposal. The thesis contains 9 chapters: introduction (Chapter 1); theoretical framework (Chapters 2, 3 and 4); methodology (Chapter 5); case study analysis and discussion (Chapters 6, 7, and 8); and conclusion (Chapter 9). The theoretical chapters explain how liberal legality recognises indigenous peoples as ethnic minorities with property entitlements, while self-determination goes a step further to recognise indigenous peoples as ‘nations’ with ‘territorial rights’. The case study chapters explore the struggle of the Awajun indigenous people for self-determination and examine the legal and political consequences of the Baguazo as well as the re-emergence of indigenous politics in Peru. The main argument provided in this thesis is that indigenous territorial defence against extractive industries expresses a politics of self-determination that confronts coloniality as the foundation of the extractive governance. Coloniality denotes that, even though colonial rule ended in formal political terms, power remains distributed according to colonial ontology and epistemology. Consequently, social and economic relationships regarding indigenous peoples still respond to an inclusion/exclusion paradox: indigenous peoples are either excluded from liberal capitalism or included into it under conditions that deny indigenous peoples’ principles. Thus, the struggle for self-determination locates many indigenous people beyond the inclusion/exclusion dialectic and promotes an extension of ‘the political’ with the aim of reconfiguring the state-form and its political economy.
