   Sammanfattning : The overarching aim of this doctoral dissertation is to present an analysis of the design processes related to serial articles produced in Sweden between 1860 and 1890. In the dissertation, the interconnections between aesthetic theories, design languague, production processes, and the commercial market are explored. LÄS MER

3. 7. Anden i lampan : etnologiska perspektiv på ljus och mörker

   Författare :Jan Garnert; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Belysning-- Sverige; Belysning-- Historia -- Sverige;

   Sammanfattning : A tallow candle gives different illumination and has other qualities than a modern halogen lamp. But in what ways have women and men changed their conceptual worlds, lifestyles and habits as a result of switching from tallow candles to kerosene lamps and then to electric light?In The Genie of the Lamp I trace and describe the link between lighting as a context and cultural processes, in particular the way people in different times, in different kinds of society, and in different social groups have related to and organized time and space.

4. 8. On voltage fluctuations in low voltage grids – characterization, propagation and impact on LED lamps

   Författare :Elena Gutierrez Ballesteros; Sarah Rönnberg; Aurora Gil de Castro; Izaskun Azcarate; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; household devices; LED lamps; light flicker; low voltage grid; voltage fluctuations; Electric Power Engineering; Elkraftteknik;

   Sammanfattning : The work presented focuses on voltage fluctuations produced by household devices and their impact on the light output of LED lamps. Voltage fluctuations can produce unsteadiness on the light intensity of the lamps, so-called light flicker. An observer may or may not experience light flicker, depending on e.g. LÄS MER

5. 9. Development of Experimental Methods, Data Analysis and Standards in Atomic Spectroscopy

   Författare :Kasper Öberg; Astronomi - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atom- och molekylärfysik; Atomic and molecular physics; ytterbium; spectroscopy; radiative lifetimes; oscillator strengths; neon; line shapes; light sources; Fourier-transform spectroscopy; branching fractions; Stark effect; spectroscopic techniques; LIF; Atomic data;

   Sammanfattning : The focus of this work is on the experimental techniques and data analysis in atomic spectroscopy. Improved methods for the analysis of spectra and the determination of level energies are presented. Most of these are based on a rigorous statistical treatment of the spectroscopic data. LÄS MER

7. 10. New diagnostic tools for malaria-challenges and opportunities

   Författare :Berit Aydin Schmidt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Nearly half of the world’s population is at risk for malaria and over 600,000 die from the disease every year. Access to prompt and correct parasite based diagnosis in order to target treatment to those with a confirmed malaria infection and improved malaria surveillance are cornerstones in malaria control.
