Remote LIBS and Raman imaging for assessment of cultural heritage

In this paper, we propose to perform remote laser-induced breakdown spectroscopy (LIBS) and Raman imaging of historical monuments to assess the state of a building. The lidar system is equipped with a Nd:YAG pumped optical parametrical oscillator (OPO) system, allowing laser radiation in the wavelength range 220 nm-4 μm. The laser radiation can be sent through a roof-top dome which can steer the r

Signatures of an Intermediate-Age Metal-Rich Bulge Population

We have determined detailed elemental abundances and stellar ages for a sample of now 38 microlensed dwarf and subgiant stars in the Galactic bulge. Stars with sub-solar metallicities are all old and have enhanced alpha-element abundances - very similar to what is seen for local thick disk stars. The metal-rich stars on the other hand show a wide variety of stellar ages, ranging from 3-4 Gyr to 12

The Contemporary Relevance of Carl Schmitt: Law, Politics, Theology

What does Carl Schmitt have to offer to ongoing debates about sovereignty, globalization, spatiality, the nature of the political, and political theology? Can Schmitt’s positions and concepts offer insights that might help us understand our concrete present-day situation? Works on Schmitt usually limit themselves to historically isolating Schmitt into his Weimar or post-Weimar context, to reading

Microbial Degradation of Toxaphene

This works deals with the degradation of a group of recalcitrant compounds known as toxaphene. Toxaphene is a complex mixture of chlorinated compounds including hexa- and octachlorocamphenes, hepta-, nona- and decachlorobornanes. Some components of toxaphene are very persistent while others are degraded rapidly by both abiotic and biotic processes. Not all components of toxaphene have been identif

Causes and consequences of individual variation in anti-predator traits

Popular Abstract in Swedish Så gott som alla djur i naturen utgör ett potentiellt byte för rovdjur. Bokstavligt talat är det därför livsviktigt att försöka undvika att bli upptäckt och fångad av sina naturliga fiender. Då olika arter exponeras för olika typer av rovdjur (predatorer) är det kanske inte så konstigt att det finns en enorm variation av försvarsstrategier i naturen. Mer förvånande är kPredation imposes a potent evolutionary force on prey, moulding the evolution of traits and diversification of species, and can furthermore have powerful ecological consequences. We know that different species vary in how they cope with their natural enemies, and, consequently, a huge range of anti-predator defences are displayed in nature. Yet there is a growing recognition that, if we zoom into

Analytical Modeling of Dune Response due to Wave Impact and Overwash

Abstract in UndeterminedAn analytical model of dune erosion was developed based on impact theory, where the weight of eroded material is assumed proportional to the impact force from waves hitting the dune. The model was validated with data from several laboratory and field studies on dune erosion covering a wide range of hydrodynamic, sediment, and geometric conditions. Overwash was then included

Himmelska visioner

A number of medieval visions of the otherworld have been preserved in writing. This article studies six such visions from the seventh to the twelfth centuries. Whereas most studies focus on what such visions have to say about hell and purgatory, this study focuses on what they have to say about heaven.
