Quick clay has been involved in most serious, large clay slides in Sweden, Norway, and Canada. This paper describes geotechnical and geophysical methods that can be used to locate and map the extent of quick clay formations. Surface resistivity measurements and four different sounding methods have been tested. The results have been compared with sensitivities determined using fall-cone tests. The
The subject of this study is the re-intensified dispute between rhetoric and philosophy in the times of the Second Sophistic. The focus of our investigation has been on two authors of this period who have left behind treatises the explicit purpose of which is to attack or defend rhetoric: Sextus Empiricus who is sharply criticising rhetoric and Aelius Aristides who is defending it. Our purpose has
The aim of this thesis is to show how modal particles can be integrated into a modular description of language where grammar and pragmatics are seen as two independent but interacting modules. The modular approach is chosen because of the problems connected with a functional approach. On the syntactic level, it is assumed that modal particles are XPs. The fact that modal particles cannot occur alo
Popular Abstract in Swedish Avhandlingen består av fyra kapitel. Efter det inledande kapitlet används i kapitel två och tre ekonomiska experiment för att undersöka hur deltagare fördelar ett överskott mellan sig då det finns två fokalpunkter. Kapitel fyra undersöker huruvida en penningpolitisk störning har asymmetriska effekter på de svenska länens sysselsättning. I kapitel två, samförfattat med This thesis consists of two parts. The first part uses economic experiments to investigate how participants choose to divide a surplus in the presence of competing focal points. The second part examines whether a monetary policy shock has asymmetric regional effects. Chapter 2 suggests a simple separation mechanism based on heterogeneity among subjects to understand how they choose equilibrium wh
This paper discusses some trends in critical theory and activist aesthetics in contemporary feminist performing arts in Sweden. The 2000s have witnessed at least two “turns” in feminist theory, namely the affective turn and the social, or as it is called here, the solidarity turn. The status of poststructuralist theory has been widely debated and Marxist, class-based analyses have returned to the
This paper deals with the quality aspects of e-learning courseware as seen by different quality stakeholders. In 2011, researchers and practitioners from more than 12 countries joined an initiative called “epprobate” with the aim of building a consensus on how to create a quality label and related consultative services for those who wish to enhance the educational value of their e-learning coursew
Abstract in Chinese 概述 学校教学最重要目的之一是赋予每个孩子同等的教育. 尽管如此, 学校再创造了社会差异. 先前的研究表明,学生的低下社会经济情况背景与自然学科成绩低下有一定联系. 这样, 不少学生在未来就被排斥在社会高端学科的教育和职业之外. 本篇论文在Bourdieu和Bernstein的理论基础上, 以自然学科课堂的社会阶级为中心, 旨在对小 学生所受的教育存在不等现象提供更多方位描述和更深层的分析. 在人种民族学的启发下, 本论文的数据取自瑞典义务小学八年级物理教室里的观察, 记录, 采访和统计调查. 1. 对教室里现象的描述和分析揭示了知识难度的下降. 这一现象的发生通常是因为自然学科的教学所具有的社会历史传统因素, 学生, 老师和教室里的谈话社交之间有无形的默契, 或被称为隐蔽的磋商, (出发点往往是善良的愿望),教室里形成了对所有学生都不利的知识难度的The overall aim of this thesis was to contribute to a more complex and multi-faceted description and analysis of inequalities in education, focusing on social class in the science classroom. Inspired by an ethnographic approach, the data was produced through observations, field notes, interviews, and a questionnaire in a Swedish compulsory school. The students aged fourteen and fifteen, were follo
While the effects of elevated atmospheric CO2 level on starch and sugar metabolism have been extensively studied in different plants, the effect on plant lipid metabolism concerns only a few studies and none of these are on the model plant Arabidopsis thaliana. This study of the lipid composition in seeds and leaves of A. thaliana is therefore of interest when trying to predict how the future envi
The idea for nature based research design emerged in preparation of a workshop and subsequent exhibition regarding minimal surfaces, supervised by Andreas Hopf, Senior Lecturer at Lund University School of Industrial Design, and supported by Prof. Dr. Konrad Polthier (Chair Mathematical Geometry Processing, FU Berlin) at the DESIGNMAI digital crafts event in Berlin in 2007, for which Swedish desig
A 0.18 mum 1.8 V CMOS transmitter for 10/100Mbps Ethernet physical layer standards is described in this paper. The circuit is substantively a current-steering digital-to-analog converter with 5-bit resolution, 125MHz sample rate and 4ns transition time. A novel latch circuit is designed, as well as a structure is provided to realize the accurate rise/fall time control of waveform
A frequency synthesizer applied to 10/100 Base-T Ethernet transceiver is described. It can work in 10Mbps or 100Mbps mode adaptively and convert from one mode to another freely. The circuit can meet both requirements of transmitter on rising/falling time and receiver on CDR so that the additional power and area are saved. Under some testing circumstance, G of voltage control oscillator jittercycle
The aim of this study is to discuss potential long term effects of online shopping on transport (both passenger and freight) and urban land use planning (e.g. structure and location of retail) with a focus on the Swedish case. The explorative approach is conducted through a mixed method approach combining the analysis of planning documents and reports, interviews with planners/private actors for t
