Quantum interference effects in electron transport through Y-branches

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

Berättelser kring Daniel av Sketis

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. A Group of Hagiographic Texts Edited with Introduction, and Commentary, Uppsala 2007 (Acta Universitatis Upsaliensis. Studia Byzantina Upsali

Modifying Cooking Practices to Reduce the Formation of Heterocyclic Amines

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

Age-related circulatory responses to whole body cooling: observations by ballistocardiographic EMFi sensors

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

Lexical inferencing procedures in L3 Italian

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
