The plasma metabolome is associated with multiple phenotypes and diseases. However, a systematic study investigating clinical determinants that control the metabolome has not yet been conducted. In the present study, therefore, we aimed to identify the major determinants of the plasma metabolite profile. We used ultra-high performance liquid chromatography (UHPLC) coupled to quadrupole time of fli

An increasing demand of higher data rates in wireless communication forces the industry to look to higher frequencies to find the required bandwidths. This thesis is about analog transmitters in CMOS for millimeter-wave communication, and it focuses on improving power amplifiers and frequency generation circuits, and increase their efficiency. This thesis starts with an introduction to millimeter-

The relationship between personality traits and cognitive performance was studied in two groups: men with symptoms and neuropsychological test results compatible with toxic encephalopathy (TE) and demographically similar healthy men (N=57 per group). Personality traits were assessed with the Karolinska Scales of Personality (KSP). The neuropsychological examination included 13 tests covering vario

Object. The aim of this study was to determine the bone lead concentration in lead smelters and reference subjects, relate them to the lead concentration in blood (B-Pb) and urine (U-Pb), and to use the measured bone lead to calculate a biological half-life for lead in bone. Method and design. The lead concentration in the second phalanx of the left index finger (bone-Pb) was determined in vivo us

Male subjects with type 2A (n = 12) and 2B (n = 12) solvent-induced toxic encephalopathy and a reference group of healthy men (n = 12) without previous solvent exposure were studied using quantitative EEG and event- related potentials from an odd-ball and a dual-task paradigm. Subjects with toxic encephalopathy of types 2A and 2B showed markedly lower P300 amplitudes than did controls in both para

A group of 38 male workers at a secondary smelter (period of employment 2-35 years; median 10 years) was divided into two subgroups depending on bone-lead concentration, arranged as 19 matched pairs according to age, education and job level. The median concentrations for finger-bone lead (Bone-Pb) were 16 vs. 32 μg/g; for current blood-lead (B-Pb), 1.6 vs. 1.8 μmol/l; for retrospective peak blood-

Artikel om möten mellan historia och konst, framför allt med fokus på såväl nationella, triumfatoriska och monumentala historier som traumatiska historier som har tolkats konstnärligt med referenser till bland annat historiemåleri och monument. Texten är skriven i anslutning till utställningen Memory Matters på Skissernas museum i Lund.

This is an article on meetings between art and history, both regarding more traditional concepts as monuments but also modern, traumatic histories interpreted by artists.

This study examines the effects of teachable agents’ expressed self-efficacy on students. A total of 166 students, 10- to 11-years-old, used a teachable agent-based math game focusing on the base-ten number system. By means of data logging and questionnaires, the study compared the effects of high vs. low agent self-efficacy on the students’ in-game performance, their own math self-efficacy, and t

Educational software based on teachable agents has repeatedly proven to have positive effects on students’ learning outcomes. The strongest effects have been shown for low-performers. A number of mechanisms have been proposed to explore this outcome, in particular mechanisms that involve attributions of social agency to teachable agents. Our study examined whether an expression of high versus low

Presentation at panel on Nordic Trust, International Anti-corruption Conference, Copenhagen. This paper argues that trust and control should not be seen as opposites, and that formulating a theory of Nordic corruption (which is based on networks and cronyism rather than bribery) a better approach is a hybrid concept of 'trusted control' or 'controlled trust'
