Konsten att göra djuren synliga

Essän tar avstamp i en installation med uppstoppade hästar av konstnären Javier Balmaseda, visad på konstbiennalen i Venedig 2013. Diskussionen rör de etiska dimensionerna vid användning av djurkroppar i konsten, med referens även till Robert Rauschenbergs getinstallation "Monogram" på Moderna museet, samt till Steve Bakers forskning om djur i konsten, inklusive den nyutgivna boken Artist Animal.

There and Back Again - nocturnal migratory behaviour of birds during spring and autumn

This dissertation explores the migratory behaviour of nocturnally migrating passerines and common swifts (Apus apus). Birds passing Lund (southern Sweden) and Abisko (northernmost Scandinavia) where sampled using tracking radar. The aim has been to investigate potential diverging strategies between spring and autumn migration. We have found that both passerines and swifts compensate for wind drift

Incomplete phonon relaxation in X-ray emission

We calculate the phonon broadening in x-ray emission for Li, Na, Al, and K, treating the excitation and the subsequent emission as one quantum process. When the core-hole lifetime width is of the same order as the Debye energy, incomplete phonon relaxation gives a partial quenching of the Stokes shift and an additional width. This effect has previously not been seriously investigated; we find here

Dynamic optimization of a plate reactor start-up supported by Modelica-based code generation software

In this paper, start-up of a plate reactor is considered. Dynamic optimization is used to obtain start-up trajectories, and a feedback control structure for on-line control. The problem is challenging, since the process model is large and highly non-linear. In addition, the plant is subject to uncertainty. Special attention is given to the problem of formulating an optimal control problem based on

Joint channel and data estimation for asynchronous GSM users

In multiple-access communication systems co-channel interference can be mitigated by applying multiuser detection instead of treating the interference as additive noise [1]. In this paper we focus on downlink operation in a GSM-like TDMA network and investigate multiuser channel estimation and data symbol detection of two users that share the same physical channel in two adjacent cells. Such a sce

The water-supply system in Roman Pompeii

This study focusses on the urban infrastructure for water supply in Roman Pompeii. The water distribution network of lead pipes was constructed inside the city walls, at the time when the city was connected to an aqueduct. Life for the Pompeiians changed considerably when aqueduct water started running continuously in street fountains all around the city. The study is based on previous research an

Missbruk av dominerande marknadsställning i Sverige och EEC

I tre artiklar, som publicerade i samfundets tidskift 1976 analyseras de åtgärder, som med stöd av den nationella konkurrensbegränsningslagstiftningen riktas mot de marknadsdominerande företagen. Tre frågor lyftes fram: 1. I vilken utsträckning beivras traditionellt missbruk av en dominerande ställning; 2. Medger den interna lagstiftningen ingrepp mot företagssammanslagningar; 3. Ger de interna re

Non-reflecting dispersive media

The modeling of non-reflecting one-dimensional dispersive media is discussed. The media are temporal dispersive with a spatially varying impedance. It is shown that the effects from the variation of the impedance can be matched by the temporal dispersive effects so that the media do not reflect any field regardless of the shape of the incident transient field. The problem of finding reflectionless

Maten märks: förutsättningar för konsumentmakt

Många människor anser sig numera ha större makt i rollen som konsumenter än som medborgare som röstar i partival. Som konsumenter kan vi idag ta ställning till en rad olika anspråk som görs på produkter och tjänster. Hur ser vi konsumenter på livsmedel som genom olika märken påstås ha unika egenskaper i produktionsledet: för miljön, för konsumentens hälsa, för arbetsförhållanden för fabriks- och
