This chapter does not deal with any practical aspects of light measurement, only with theoretical concepts. The following concepts are explained: energy fluence, energy fluence rate, photon fluence, photon fluence rate, radiance and mol, as well as the following superfluous or obsolete terms and synonyms: actinic flux, space irradiance, scalar irradiance, spherical irradiance, vectorial irradiance
Within the newly decided scheme for CE-marking of cables1 a full-scale fire test for cables (prEN503992) has been introduced. The new test measures heat and smoke production rates and flame spread and in some cases requires large amounts of cables. In the project presented here a modelling tool was developed to predict full-scale results using data from the small-scale fire test Cone Calorimeter.
This paper introduces means for fatigue damage rates estimation using Laplace distributed multiaxial loads. The model is suitable for description of stresses containing transients of random amplitudes and locations. Explicit formulas for computing the expected value of rainflow damage index as a function of excess kurtosis are given for correlated loads. A Laplace model is used to describe variabi
The refugee crisis is also a crisis in education. While attention is frequently directed toward primary and secondary school levels, higher education is a strategic issue for refugees, both as individuals and for long term processes of post-conflict recovery and peacebuilding. Education prospects and content are drivers of onwards migration, but also affect economic structures on return. Higher ed

In heterogeneous catalysis the reactions occur on the surface of a catalyst. To understand the reaction pathways, a detailed understanding on an atomic level is critical. However, the gas atmosphere surrounding the surface dictates the interaction between the surface and the gas. At low pressures this is often neglected, but as the community turns to higher pressures it becomes important to consid
The end-Ordovician extinction consisted of two discrete pulses, both linked, in various ways, to glaciation at the South Pole. The first phase, starting just below the Normalograptus extraordinarius Zone, particularly affected nektonic and planktonic species, while the second pulse, associated with the Normalograptus persculptus Zone, was less selective. Glacially induced cooling and oxygenation a
Most organisms that ever lived on Earth lacked skeletons and have therefore escaped preservation in the geological record. This fact makes it hard to accurately trace the evolution of multicellular organisms and the tree of life. However a handful faunas did get exceptionally well-preserved, including their soft-bodied members, just when complex lifeforms diverged 550 million years ago. Geochemica
The Fourier slice theorem for the standard Radon transform generalizes to a Laplace counterpart when considering the exponential Radon transform. We show how to use this fact in combination with algorithms for the unequally spaced fast Laplace transform to construct fast and accurate methods for computing both the forward exponential Radon transform and the corresponding back-projection operator.
MAX IV-laboratoriet är en anläggning med syfte att producerasynkrotronljus till forskning. När laddade partiklar accelereras skickar de ut energi i form av strålning kallad synkrotronljus. Synkrotronljus är intensivt ljus med många olika våglängder och är därför väldigt användbart för att studera strukturer och processer inom många olika fält såsom materialforskning, medicin, geologi och arkeologiThe MAX IV facility includes two storage rings, operated at 1.5 and 3 GeV energy, for the purpose of producing high-brilliance synchrotron radiation for users. The 1.5 GeV ring replaces the previous MAX II and MAX III storage rings as a source of UV and soft X-rays, whereas the 3 GeV ring is optimized for hard X-rays. The 3 GeV ring is the first of a new generation of synchrotron light storagering
This article presents a comprehensive integration of current experimental evidence and theories about so-called parapsychological (psi) phenomena. Throughout history, people have reported events that seem to violate the common sense view of space and time. Some psychologists have been at the forefront of investigating these phenomena with sophisticated research protocols and theory, while others h
Article 83(2) TFEU, introduced by the Treaty of Lisbon, confers a power on the EU to harmonise Member States’ legislation to define criminal offences and criminal sanctions. Nonetheless, uncertainty persists as to whether this provision exhaustively determines the EU’s power to adopt criminal law to enforce its policies. The article outlines the core case for viewing art.83(2) TFEU as a lex specia
Over the last two decades the market for membrane technology in the food industry increased to a market volume of approx. € 50 million and is now the second largest industrial market for membranes after municipal water treatment in Germany. The key membrane technologies in the food industry are the pressure driven membrane processes; microfiltration, ultrafiltration, nanofiltration and reverse os
We present a new model for building up complete exclusive hadronic final states in high energy nucleus collisions. It is a direct extrapolation of high energy pp collisions (as described by Pythia), and thus bridges a large part of the existing gap between heavy ion and high energy physics phenomenology. The model is inspired by the old Fritiof model and the notion of wounded nucleons. Two essenti
After the first description of the inherited nature of bimodal deaf-blindness disease in mid nineteenth century by pioneering ophthalmologists Albrecht von Graefe (May 22, 1828 ± July 20, 1870) and Richard Liebreich (June 30, 1830 - January 19, 1917) followed by its confirmation in early twentieth century from a larger number of patients by another pioneer ophthalmologist Charles Howard Usher (Mar
Sustainable business model innovation is increasingly viewed as a lever for systems change for sustainability across businesses and industries. Banks hold a unique intermediary role in sustainable development, but also have a difficult position after the 2008 financial crisis. This paper aims to explore business models for sustainability in the service industry, particularly banking. It explores t
