Recently, nonlinear properties of three-terminal ballistic junctions (TBJs) were predicted by theoretical calculations done by Xu, and potential applications such as rectification and logic function proposed. In that analysis the TBJ was modeled by connecting three quantum point contacts via a ballistic cavity with adiabatic boundaries, thus neglecting any backscattering of electrons. In this pape
Översättning från grekiska till svenska av två berättelser relaterade till Daniel från Sketis: Kvinnan som låtsades vara en dåre och Anastasia Patrikia. Översättningen bygger på den grekiska versionen som publicerades i Britt Dahlman, Saint Daniel of Sketis.

Popular Abstract in Swedish Vid tillagning av kött, och framför allt stekning och grillning, bildas mutagena ämnen i stekskorpan. Dessa ämnen benämns heterocykliska aminer. Flera epidemiologiska studier har visat ett samband mellan uppkomsten av cancer och intaget av heterocykliska aminer, medan några studier inte finner något samband. Ämnena har också visat kunna utveckla tumörer och cancer i djuCommonly cooked meat dishes contain heterocyclic amines (HAs) at ng/g levels. HAs are animal carcinogens, form DNA adducts in human tissues, and have been associated with increased risk of cancer in epidemiological studies, and it is thus recommended that human intake be decreased. The aim of this investigation was to find ways of modifying cooking practices to reduce the formation of HAs. Various
The purpose was to study age related changes in circulatory system via Ballistocardiography (BCG) by utilizing Electromechanical Film (EMFi) sensors by gradually changing the ambient temperature from a thermoneutral area to cold direction. ECG and BCG were recorded from a young person (23 years) and from an older person (78 years), both males. During the tests, brachium blood pressure (BP) and pul
This study is aimed at investigating and describing the different procedures of foreign language learners of Italian when they infer the meaning of unknown words in a written authentic text. Vocabulary is a crucial component in the learning process of a foreign language and many studies show that lexical inferencing is one of the most important strategies when foreign language learners encounter u
Popular Abstract in Swedish Målet för ceramologisk forskning är att studera och beskriva keramikhantverkstraditioner : krukmakarna, deras produktion och sociala organisation samt användningen af keramikprodukterna. Kunskapen om keramiken gör det möjligt också att studera de mänskliga handlingarna, som keramiken tog del i. Den föreliggande avhandlingen söker att avtäcka kontakt-mönstre mellan olikaThe objective of ceramology is to describe pottery craft traditions; the potters, their production, social organisation and the use of the products. Through this the human actions surrounding the pottery are studied. The objective of the research presented in this thesis is to study patterns of contacts between different, contemporary sites within a limited area through a ceramological analysis of

In this article an analytical and empirical model for describing tool life and tool wear in metal cutting is presented. The model is based on combining the Colding tool life equation and an extended version of the Archard wear function. It is shown that through the combining of these two models a substantial saving of resources can be achieved in terms of the workpiece material required, as well a
Spectral tuning is a diverse topic, both with regard to mechanism and with regard to biological significance. We have touched upon a related topic already when dealing with quantum dots in Chapter 5. In organisms, spectral tuning can be achieved both by chemical means (choice of pigment) and by physical means. The latter aspect is treated towards the end of the chapter in a section on structural c
