Tidskriftsartikel (refereegranskat)abstract
- The fall of the Soviet Union is analysed in conceptual terms, drawing on Reinhart Koselleck’s Begriffsgeschichte. The author seeks to interpret the instrumental role of the concepts perestrojka, glasnost´, reform, revolution, socialist pluralism, and acceleration in the Soviet collapse. The semantics and pragmatics are related to a wider intellectual and political context, and the conceptual perspective is used to help explain the progress of events. The author argues that the common notion of the reform policy concepts as clichés is not valid.

Possibilities and constraints of implementing starch consolidated high speed steel in prototyping

- In the starch consolidation (SC) process, a water-based slurry containing powder, starch, dispersant and thickener is used to fabricate near net-shape green bodies that are de-binded and further consolidated by sintering. In this study, gas atomized M3/2 as well as high and low carbon V-rich M4 type high speed steel powder (<150 mu m) are considered, Both material types undergo high volumetric shrinkage during super-solidus liquid phase sintering enabling them to reach near full density. The analyses and the review cover different process aspects like: recipe optimisation, post-gelatinization drying, de-binding and sintering. A SC recipe consisting of 58 vol.% powder, 3 vol.% starch, 1 vol.% dispersant and a thickener solution resulted in a density of >98% than what is theoretically stated after sintering. It is found that the success of the post-gelatinization drying procedure depends on the smoothness of mould material and controlling powder oxidation. The best combination was freeze drying the slurry in a silicon rubber mould. For V-rich alloys a total or partial control of eutectic carbides in the final microstructure could be realized for vacuum and nitrogen sintering atmospheres, respectively.

MEMS Sensor for in Situ TEM Atomic Force Microscopy

Tidskriftsartikel (refereegranskat)abstract
- Here, we present a MEMS atomic force microscope sensor for use inside a transmission electron microscope (TEM). This enables direct in situ TEM force measurements in the nanonewton range and thus mechanical characterization of nanosized structures. The main design challenges of the system and sensor are to reach a high sensitivity and to make a compact design that allows the sensor to be fitted in the narrow dimensions of the pole gap inside the TEM. In order to miniaturize the sensing device, an integrated detection with piezoresistive elements arranged in a full Wheatstone bridge was used. Fabrication of the sensor was done using standard micromachining techniques, such as ion implantation, oxide growth and deep reactive ion etch. We also present in situ TEM force measurements on nanotubes, which demonstrate the ability to measure spring constants of nanoscale systems.

- We construct lattices with quadratic structure over the integers in quadratic number fields having the property that the rank of the quadratic structure is constant and equal to the rank of the lattice in all reductions modulo maximal ideals. We characterize the case in which such lattices are free. The construction gives a representative of the genus of such lattices as an orthogonal sum of "standard" pieces of ranks 1-4 and covers the case of the discriminant of the real quadratic number field congruent to 1 modulo 8 for which a general construction was not known. © 2007 Springer-Verlag.

- Compulsory School Curricula of South Africa (RNCS1, 2002) and Sweden (Lpo 294).AbstractThe aim of this paper is to analyse the compulsory school curricula of South Africa and Sweden. It focuses on contexts for their introduction, main actors in the process, democratic values they contain and their similarities and differences. Norman Fairclough’s Critical Discourse Analysis (CDA) is used for analysis. The curricula and references to other literatures show similarities and differences. Contextual similarities are that both countries were once under oppression and their masses were isolated from the education process and more resources were invested on their elites. At present the curricula of both countries strives for democratic education. A major difference is equal opportunities for the students to attend a school of their choice are higher in Sweden than in South Africa. The Swedish curriculum is more concrete on issues related to students, teachers and other school staff’s rights and responsibilities, and on relations between school, home and society.Key words: South Africa, Sweden, Curricula, and Democratic values

La recuperación de la identidad en la novela Sefarad de Antonio Muñoz Molina
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of the present study is to examine the signification of identitary discourses in the novel Sefarad: Una novela de novelas by Antonio Muñoz Molina and determine to what extent these discourses represent and respond to identitary discourses in contemporary Spanish society. The analysis focuses on three principal questions: how is the narrative constructed, what is conveyed as a result, and what is the aim of the narrative. Identity is understood as a social construction, an individual and continuous process of assuming, defining, negotiating and maintaining cultural identities, elements of the surrounding world that provide the individual with a sense of meaning (Fromm 1956; Castiñeira 2005; Marsella 2008). The novel consists of different stories that manifest the social impact of the totalitarian regimes in Europe during the twentieth century, told by a diversity of voices. First, the analysis deals with the structure of the text, examined through the model of mise en abyme (Dällenbach 1989). Secondly, the significations of transition, transgression (Lotman 1978) and, analogically, stigmatization are deduced (Goffman 1972), processes that are related to the effects of the frontier as a metaphor (Pratt Ewing 1998) and to limit situations (Jaspers 1974). Thirdly, the study stresses the representation of the past, in which trauma, melancholy and mourning are significant (Benjamin 1992; Freud 1986). The conclusions confirm the claim that the novel corresponds to humanity’s treasure of suffering (Leidschatz), a cultural possession that thematizes the processes of memory and oblivion (Assmann 1999), represented through stories told by the victims of intolerance at different levels. The text is accordingly conceived as a mirror through which the narrator constructs his identity as a writer and transmits meaning to the reader by providing the opportunity to reflect upon identity issues today.
