The article examines the writing skills of three 11th-grade students who took the California Standards Test (CST). The essays formulated by the students about the book "The Bluest Eye," by Toni Morrison are highlighted. According to the author, the performance level of the students demonstrate the development of academic literacy identities that transcend their standardized exam labels.

Electro discharge machining (EDM) causes a white layer at the surface of a workpiece. The research work, described in this paper, aims to acquire a profound knowledge of this layer. The influence of workpiece material, electrode material and type of dielectric on the COMPOSITION and the metallographic phases of the white layer is discussed. The measurements yield that the use of an oil dielectric increases the carbon content in the white layer. A water dielectric on the other hand, causes a decarbonisation. The carbon in the white layer machined in an oil dielectric appears as iron carbides (Fe3C) in columnar, dendritic structures. This is a result of the very rapid re-solidification of the molten material. In between the carbide dendrites, rest austenite and also some ferrite can be found.
A widely used class of quantitative trade models implicitly assumes that patterns of comparative advantage take a specific form such that they have no influence over the effect of trade barriers on aggregate trade flo...

A ten member microbial consortium (AS) consisting of eight phenol-degrading and two non-phenol-degrading strains of bacteria was developed and maintained in a fed-batch reactor by feeding 500 mg l(-1) phenol for four years at 28 +/- 3 degreesC. The consortium could degrade 99% of 500 mg l(-1) phenol after 24 hours incubation with a biomass increase of 2.6 x 10(7) to 4 x 10(12) CFU ml(-1). Characterization of the members revealed that it consisted of 4 principal genera, Bacillus, Pseudomonas, Rhodococcus, Streptomyces and an unidentified bacterium. Phenol degradation by the mixed culture and Bacillus subtilis, an isolate from the consortium was compared using a range of phenol concentrations (400 to 700 mg l(-1)) and by mixing with either 160 mg l(-1) glucose or 50 mg l(-1) of 2,4-dichlorophenol in the medium. Simultaneous utilization of unrelated mixed substrates (glucose/2,4-dichlorophenol) by the consortium and Bacillus subtilis, indicated the diauxic growth pattern of the organisms. A unique characteristic of the members of the consortia was their ability to oxidize chloro aromatic compounds via meta pathway and methyl aromatic compounds via ortho cleavage pathway. The ability of a large membered microbial consortia to maintain its stability with respect to its COMPOSITION and effectiveness in phenol degradation indicated its suitability for bioremediation applications.

An interview with Ivajla Kirova, a Bulgarian-born pianist and composer who lives and works in Munich, Germany, is presented. It notes that Kirova has initiated a concert series that features Bulgarian music at that city's Nymphenburg Palace, besides playing the music of the most famous composers and some of her own COMPOSITIONs in concert halls around the world. Kirova is considered as successful pianist and published poet, apart from being a wife and mother who balances family and career.

An interview with Martin Pearlman, founder of Boston Baroque, considers as the first U.S.-based period instrument orchestra, is presented. He says that he wanted to record the oratorio "The Creation," by Joseph Haydn as he loves it. He emphasizes that in his version of this oratorio, he uses an ensemble within the range of what Haydn used in his performances. He also stresses that Haydn is considered as the greatest composer of his time and this oratorio represents his crowning achievement.

An interview with Canadian classical composer Nick Peros is presented. He provides an overview on his musical background before coming to classical music which focuses on playing and listening to rock music. He highlights the lessons taught by musical COMPOSITION teacher Peter Dawson. He emphasizes the influence of Russian composer Alexander Scriabin on his musical COMPOSITIONs.
