The prevalence of illnesses related to the modern diet and a more sedentary lifestyle has increased markedly over the last few decades. There is therefore a need for effective strategies to promote health and to reduce the prevalence of diet-related diseases. In this paper, we study the willingness to pay for a new concept, healthy canteen takeaways. In the analysis, we depart from a household pro
Popular Abstract in Swedish I denna avhandling presenteras en ny typ av röntgenkälla baserad på ett laser-producerat plasma. Röntgenstrålning alstras genom att fokusera laserpulser på ett strålmål. Energin i de enskilda laserpulserna blott är cirka 150 mJ, men tack vare den extremt korta pulstiden 100 fs (10E-13 s), blir laserns toppeffekt mer än 1 TW (10E12 W). Den extremt intensiva laserstrålninA laser-produced plasma was generated by focusing 100 fs laser pulses, with an energy of 150 mJ, onto metal targets. The laser intensity was expected to reach 10E17 W/cm2. Radiation was emitted from the created plasma, with photon energies extending up to the MeV regime. The laser-based X-ray source was optimised, with the purpose of making it a realistic source of hard X-rays (>10 keV). Dedicated

Presented at the Roundtable on NGOgraphy, American Anthropological Association Annual Meetings, Denver, 17 November 2015. This chapter describes the dialectic between fieldwork engagement
Popular Abstract in Swedish Järn har den kemiska beteckningen Fe från latinskans ferrum. Det är det fjärde vanligaste ämnet i världen och utgör ca en femtedel av jordskorpan. Trots det kan både djur och växter ha järnbrist. Hur kan detta vara möjligt? Problemet är egentligen inte förekomsten av järn utan att järnet som vi och alla andra organismer behöver har oxidationstillståndet Fe(II) medan detIt is of vital importance to understand the systems for iron metabolism and this thesis contributes to this by providing insights into the structure and function of the acquisition and homeostasis of iron. The two proteins that have been primarily investigated are a ferric reductase from Arabidopsis thaliana called FRO2 and a mitochondrial iron chaperone from Saccharomyces cerevisiae called fratax
In this paper a method for reconnecting islanded distributed generation systems is presented. Islanding of a distributed generation system may result from a fault or malfunction of protective elements. The behavior of local voltage and frequency control in case of islanding is investigated. A method for reconnecting the distributed generation system and the behavior of voltage and frequency contro
The degradation of different polyethylenes, LDPE, LLDPE, and HDPE, with and without antioxidants and at different oxygen concentrations in the polymer granulates have been studied in extrusion coating processing. The degradation was followed by On Line Rheometry, Size Exclusion Chromatography, Surface Oxidation Index measurements, and GC-MS Chromatography. The degradations starts in the extruder w
In a world where distributed power generation and deregulation of energy markets are on everyone's agenda, the need for highly efficient power plants with short lead times is greater than ever. Although at present combined cycles provide a solution, development of ever more advanced machines to increase efficiency and lower the environmental impact has led to high maintenance costs and a decrease
The epitome of this article is the reflection upon the question of “How long is now?” This question is interpreted within the context of the Iraq war, 2003 and onwards, as the enduring now specified. Drawing on parallels from the European World War II experience and the use of “Auschwitz” as a metaphor for a specifically Christian guilt articulated in relation to the Pauline eschatological hope of
Sweden, like most other industrialized countries, has an aging population. This is caused by decreases in fertility as well as increases in life expectancy. Table 6.1 shows the percentage of the population over sixty-five and eighty-years-old.
Many communication systems obtain enhanced performance by using concatenated coding schemes. Turbo codes and woven convolutional codes are two examples of such schemes. The component codes used in these schemes operate at rates close to or even above capacity where the free distance of a code is not relevant anymore and other distance properties have to be taken into account. This thesis consists
It is important to measure the relative humidity, RH, level in a concrete slab before applying semi permeable flooring to the surface. If the moisture level in the concrete is too high when the flooring is applied the high alkali level in combination with the moisture will degrade the adhesive. This paper describes a new system used to continuously measure and monitor RH in situ during the constru
