    [Review of] Teodros Kiros, ed. Explorations in African Political Thought: Identity, Community, Ethics

    Get PDF
    Explorations in African Political Thought: Identity, Community, Ethics is a collection of ten essays written both by newcomers and by well-known African philosophers. Most of the authors are currently teaching in American universities. It is part of the growing literature that cements African philosophy as an integral part of the discipline of philosophy while charting new venues for the field. The objective of this book is to illustrate that African philosophy can serve African people as a moralactivity guided by the principles of practical reason in addressing the underlying problems of African economic, political, and social institutions. Teodros Kiros, the volume\u27s editor, chose the contributors because they were willing to describe phenomenologically entrenched practices of today\u27s Africa, subject them to critical assessment, and, when necessary, displace them with better visions and research. Kiros writes in the introduction that the authors address perennial cultural, political, and ethical problems that plague the human condition in Africa

    This is a report of a Master’s thesis done in behalf of the local network in Stockholm, under Fortum Distribution AB. The thesis was to conduct a review of a distribution station named Fs MyrĂ€ngen located in TĂ€by. A model was created for the 11 kV network linked to the secondary side of Fs MyrĂ€ngen. Based on this model and using symmetrical components, theoretical fault currents (short circuit and ground fault) could be calculated. The results of these fault currents are used to investigate and develop new settings for relay protection and ground equipment in the station. The results of the calculated fault currents were also used to investigate unwanted voltages that occurs for grounded parts due to earth faults. The value of these unwanted voltages was then compared to heavy current regulations developed by the Electrical Safety Authority in Sweden. Another element of the work was to create a rehabilitation plan for the structure on the 11 kV side of Fs MyrĂ€ngen, the main goal regarding the rehabilitation plan was to investigate the advantages and disadvantages that exist at a possible transition to numerical protection relays. This was done by making a market overview of the different types of numerical protection relays and compare these with the existing analog protective device in Fs MyrĂ€ngen. The study showed that protective relay settings should be revised according to the recommendations in the report, ground equipment should be replaced with a self-regulating type, transformers should be replaced due to age and capacity limitations. Regarding a switch to numerical protection relays the type REF615 from ABB was recommended, in that case the control board in the station should be replaced to a station computer. Furthermore should current transformers be replaced to recive a desired sensitivity regarding detection of ground faults. The report also showed that Fs MyrĂ€ngen meets the regulations of unwanted voltages over grounded parts in distribution stations due to earth faults.Detta Ă€r en rapport av ett examensarbete utfört i uppdrag av lokalnĂ€t Stockholm under Fortum Distribution AB. Examensarbetet gick ut pĂ„ att göra en översyn av en fördelningsstation vid namn Fs MyrĂ€ngen som Ă€r belĂ€gen i TĂ€by. En modell skapades av 11 kV nĂ€tet kopplat till Fs MyrĂ€ngen, utifrĂ„n denna modell samt med hjĂ€lp av symmetriska komponenter berĂ€knades teoretiska felströmmar bĂ„de för kortslutning och jordslutning. Resultaten av dessa felströmmar anvĂ€ndes för att utreda och ta fram instĂ€llningar pĂ„ relĂ€skydd och nollpunktsutrustning i stationen. Resultaten pĂ„ framrĂ€knade jordfelsströmmar anvĂ€ndes Ă€ven för att utreda vilken spĂ€nningssĂ€ttning som uppstĂ„r vid jordfel, i de nĂ€tstationer som matas av Fs MyrĂ€ngen. SpĂ€nningssĂ€ttningen pĂ„ nĂ€tstationerna jĂ€mfördes sedan med de starkströmsföreskrifter som Ă€r framtagna av elsĂ€kerhetsverket. Ett annat moment i arbetet var att skapa en upprustningsplan för skyddsanordningen pĂ„ 11 kV sidan i Fs MyrĂ€ngen, huvudmĂ„let för den biten var att utreda vilka fördelar och nackdelar som finns vid en eventuell övergĂ„ng till numeriska skydd. Detta gjordes genom att göra en marknadsöversikt över olika typer av numeriska relĂ€skydd, samt jĂ€mföra dessa med den befintliga skyddsanordningen i MyrĂ€ngen som Ă€r av analog typ. Studien visade att relĂ€skyddsinstĂ€llningar bör ses över enligt rekommendationer i rapporten, nollpunktsutrustningen bör bytas ut till sjĂ€lvreglerande typ, transformatorerna bör bytas ut p.g.a. Ă„lder och kapacitetsbegrĂ€nsning. GĂ€llande skyddsanordningen rekommenderas en övergĂ„ng till numeriska skydd av typen REF615, och i samband med detta byta ut den befintliga kontrolltavlan i stationen till en stationsdator. Vidare bör Ă€ven strömtransformatorer för jordfelsskydden bytas ut för att uppnĂ„ önskad kĂ€nslighet gĂ€llande detektering av jordfel. För spĂ€nningssĂ€ttning av nĂ€tstationer vid jordfel, visar resultaten att stationen uppfyller kraven enligt starkströmsföreskrifterna frĂ„n elsĂ€kerhetsverket

    [Review of] Henk van Woerden. The Assassin: A Story of Race and Rage in the Land of Apartheid. Translated by Dan Jacobson.

    This small volume deserves to be read by those engaged in the study of modern South Africa. It also has interests for students of biography. The Assassin: A Story of Race and Rage in the Land of Apartheid is the first biography of Demitrios Tasfendas. Were it not for his assassination of Dr. Hendrik Verwoerd, the South African Prime Minister, Tsafendas most likely would not have merited even a historical footnote. The Assassin saved Tsafendas from the historical anonymity accorded to the assassins of 20th century notables such as the Archduke Francis Ferdinand and his wife Princess Sophie, Mohandas Gandhi, Martin Luther King, Jr., and John F. Kennedy
