A three-terminal ballistic junction (TBJ) is a device in which three quantum point contacts are coupled via a ballistic region. Previous studies have shown that the TBJs exhibit a novel electrical property which has potential applications in nanoelectronics. Here, based on our recent theoretical and experimental investigations, we will demonstrate that various nanoelectronic devices can be fabrica
Popular Abstract in Swedish Magnetkameran är ett diagnostiskt instrument med vilket man kan ta skiktbilder av kroppen. Den började användas i sjukvården för drygt 20 år sedan och baseras på ett fysikaliskt fenomen som kallas för kärnmagnetisk resonans (MR). Detta innebär att vissa atomkärnor som placeras i ett starkt magnetfält kan avge en radiosignal när de utsätts för korta radiopulser. RadiosigContrast-enhanced magnetic resonance angiography (CE-MRA) is a diagnostic method for imaging of vascular structures based on nuclear magnetic resonance. Vascular enhancement is achieved by injection of a contrast medium (CM). Studies were performed using two different types of CM: conventional paramagnetic CM, and a new type of CM based on hyperpolarized (HP) nuclei. The effects of varying CM con
An interesting class of intelligent tutoring systems are systems that are able to detect and recognize affective responses and states in students, and use such data to adapt its feedback, guidance and instruction. The article presents affective responses and states considered relevant for learning, and methods that have been proposed or used to detect such responses and states. We focus on the aff
The present thesis concerns middle-aged women’s subjective well-being (SWB). The interest is focused on the importance of childhood factors, social circumstances, and personality for middle-aged women’s general SWB. Data were taken from the longitudinal research program Individual Development and Adaptation (IDA, Magnusson & Bergman, 2000) and concerned a sample of about 300 women. The main an
Objective: To investigate glycaemic and satiating properties of potato products in healthy subjects using energy-equivalent or carbohydrate-equivalent test meals, respectively. Subjects and setting: Thirteen healthy subjects volunteered for the first study, and 14 for the second. The tests were performed at Applied Nutrition and Food Chemistry, Lund University, Sweden. Experimental design and te
Animals can detect different parameters of the geomagnetic field by two principal independent magnetoreception mechanisms: (1) a light-dependent process detecting the axial course and the inclination angle of the geomagnetic field lines, providing the animals with magnetic compass information (inclination compass), and (2) a magnetite-mediated process, providing magnetic map information (map sense
I kapitlet om religion sätts fenomenet religion i relation till IMER-fältet. Med kapitlet vill författaren lyfta fram den komplexitet som finns i begreppet religion i relation till migration och genom att problematisera begreppet religion - och begreppet IMER – visa hur en beredare förståelse skapas för hur dessa förhåller sig till varandra. Kapitlet börjar med en genomgång av vad religion kan var
Popular Abstract in Swedish De flesta barn föds efter i genomsnitt 40 fullgångna graviditetsveckor. Cirka 4,2%, dvs vart tjugofemte barn i Sverige föds emellertid för tidigt - prematurt - vilket innebär att barnet föds före 37 fullgångna graviditetsveckor. Att förlossningen startar i förtid kan bero på sjukdomar eller avvikelser hos modern eller fostret, men i många fall är orsaken inte klarlagd. In this longitudinal, prospective study, 39 preterm children, consecutively born before 35 weeks of completed gestation and 23 full-term children were followed up after 19 years. Multifaceted aspects of outcome were evaluated. The results indicate a clear increase in somatic morbidity during growth and young adulthood among the preterms. Psychometric evaluation of cognitive development at age 19 y
