The universally recognised action spectrum for the UV-induced conversion of 7-dehydrocholesterol to previtamin D3 in human skin was published in 1982, and indicates a maximum at about 297 nm with essentially no production above 315 nm. This work represents a milestone in research on vitamin D, but limitations in the original data should be recognised. Various findings have arisen in recent years w

The study of labour markets in a historical perspective reveals comprehensive structural change and enormous progress regarding the organization and compensation of labour with implications for economic growth and individual well-being.

Denna uppsats syftar till att undersöka samspelet mellan principen om jämbördig suveränitet stater emellan och möjligheterna för rättslig prövning och verkställighet av mänskliga rättigheter. I synnerhet undersöks rätten till hälsa, såsom den redogörs för i International Covenant on Economic, Social and Cultural Rights. Uppsatsen innehåller en sammanfattning av suveränitetsteorin och dess klassiThis thesis seeks to examine the interplay of the theory of equal sovereignty between states and justiciability of human rights, in particular the right to health, as enshrined in the International Covenant on Economic, Social and Cultural Rights (ICESCR). The essay contains an overview of the theory of sovereignty, divided into its two main paradigms of thought, namely universalism and particula

In this paper a simple analytical method is introduced for calculating the overall thermal conductivity of a twin pipe in district heating network. The method is developed based on calculating the conductive and convective heat transfer around the casing pipe in different perimetral sections. Temperature inside the supply and return pipes and also over the heating pipe is measured on different poi

In the present study, the involvement of cytochrome P450 enzyme( s) in the primary metabolism of laquinimod, a new orally active immunomodulator, has been investigated in human liver microsomes. Hydroxylated and dealkylated metabolites were formed. The metabolite formation exhibited single enzyme Michaelis-Menten kinetics with apparent K-M in the range of 0.09 to 1.9 mM and V-max from 22 to 120 pm

In Europe, willow (Salix spp.) trees have been used commercially since the 1980s at a large scale to produce renewable energy. While reducing fossil fuel needs, growing short rotation coppices (SRCs), such as poplar or willow, may have a high impact on local air quality as these species are known to produce high amounts of isoprene, which can lead to the production of tropospheric ozone (O3). Here

Whistle-blowing can serve as a powerful mechanism helping policy-makers and other stakeholders recognize ethical misconduct and other types of wrongdoing in autonomous public agencies. This mechanism is of particular importance in major public sector reforms, such as agency mergers, when it may be difficult to secure continuity in the quality of organizational processes. Yet, we know little of wha
