We have investigated the oxidation/reduction behaviour of dome-shaped three-dimensional islands of Ge on Si(001) grown by UHV-CVD at 620°C. The oxidation was done by exposing the surfaces to a steam of H2O in N2. The reduction was done in H2, which at T<800 °C selectively reduces GeO2 only. The results of the oxidation/reduction processes under varying c
Syftet med denna rapport är att närmare beskriva hur laborationer används i de obligatoriska kurserna på kemiteknikprogrammets tre första år, och att analysera hur de tillsammans uppfyller de mål som beskriver kemiteknikprogrammet, samt att kartlägga i vilka kurser som olika färdigheter lärs ut. Vidare har i rapporten inkluderats en utvärdering baserad på CEQ utvärderingar på hur studenter uppfatt
A large part of New Testament and Early Christian Literature deals with practical advice on how a Christian ought to live. The form as well as the content of this teaching is closely related to Classical literary traditions and the ethos of Greek philosophies. In the article, which ends a large volume from a Nordic project on Paraenesis, some of the most important early monastic texts are studied
Artikeln söker förklara varför de svenska tjänstemännen organiserade sig i egna fackförbund och centralorganisationer (Sverige har världes mest socialt segregerade fackliga rörelse genom uppdelning på särskilda fackföreningar för arbetare, akademiker och övriga tjänstemän)
Block transmission over noisy communication channels is characterized by two performance criteria: the bit error probability P/sub b/ and the block error probability P/sub B/. If P/sub B/ goes to zero when N/spl rarr//spl infin/ (where N denotes the length of the permutors), P/sub b/ also must go to zero for all symbols in the block but, in general, the reverse is not true. Therefore we formulate
This paper shows a novel methodology to reduce the complexity in unrolled CORDIC architectures. The methodology is based on eliminating the CORDIC stages starting from the first stage. As an example, a six stage CORDIC is used but the methodology is applicable on CORDICs with an arbitrary number of stages. The paper shows that the complexity can be reduced by 25%.
Within a course in academic writing, first-term students of English currently construct individualized study-plans detailing both what they should do during the term and when they should do it. Students calculate the average workload for all their courses, and include in their study-plans all the hours they should spend both in and outside the classroom on each course, totalling in 40-hour working
Popular Abstract in Swedish Syftet med denna studie är att försöka förklara varför araméen Laban, vilken i Bibeln (Genesis) framstår som en ganska harmlös bifigur, i rabbinsk litteratur i allmänhet betraktas som en av Jakobs och därmed Israels stora fiender. Avhandlingen hävdar att bilden av Laban som en skurk utvecklats som ett resultat av rabbinsk hermeneutik och att de egenskaper som tillskrivsThis study attempts to answer the question of why Laban the Aramean, a rather harmless character as presented in the biblical text, is generally portrayed in rabbinic literature as a major enemy of Jacob and Israel. It is argued that the portrait of Laban as a villain developed as a result of rabbinic hermeneutics, and that the characteristics which are attributed to him in rabbinic literature wer
Mellanstatliga organisationer är självklara inslag i den internationella miljön. Organisationerna ger stadga åt internationellt samarbete och skapar nödvändiga diskussionsforum där stater och andra aktörer kan lösa gemensamma problem. Sverige, via politiker, parlamentariker och tjänstemän, är aktivt i mängder av mellanstatliga organisationer, och arbetet i dem får ofta stor genomslagskraft. Trots
The aim of this article was to analyze the retold experiences of 27 survivors from the 1990s war in Bosnia and Herzegovina. I have examined verbal markers of reconciliation and implacability and I have analyzed described terms for reconciliation that are being actualized in the narratives. In the narratives of those interviewed, implacability is the prominent them, but the possibility of reconcili

Two things strike the eye in the literature and debate on the impact of agricultural research. Firstly, it is not unsurprisingly dominated by economists using cost-benefit analysis. Secondly and more surprisingly, much space is devoted to the discussion of counterfactuals, i.e. by an argument of the type: “If this research had not been made, yield development (or whatever indicator) would have bee
Popular Abstract in English The work presented here is about methods that will enable more precise estimates of soil and rock parameters related to seismic hazard mapping, in particular when resources are limited. This will allow for evaluating the seismic risk in countries where earthquakes are frequent and large budgets are not available. Particularly, the study of ground response due to the eneIn sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. In common practice the active MASW method is implemented using a sledgehammer source and a linear receiver spread. This method is lim
