Polarized light is a key feature of the blue sky, used by many animals as a sensory cue for compass navigation. Like other insects, locusts perceive the E-vector orientation of polarized light with a specialized region of their compound eye, the dorsal rim area. Neurons in the brain relay this information through several processing stages to the central complex. The central complex has a modular n

High air concentrations of ammonium were detected at low and high altitude sites in Sweden, Finland and Norway during the spring 2006, coinciding with polluted air from biomass burning in eastern Europe passing over central and northern Fennoscandia. Unusually high values for throughfall deposition of ammonium were detected at one low altitude site and several high altitude sites in north Sweden.

Users of Business Intelligence (BI) systems have started to demand more flexible systems in which they could be empowered to serve themselves – self-service BI. In this paper we aim at explaining how such development influences designers of BI solutions and how it impacts the design situation. To say something about this we adapted the PACT (People, Activity, Context, Technology) framework on the

The introduction of turnpike trusts has been considered to be an integral part of the rapid decline in transport costs in England. Institutional change in the transport system or the lack thereof has been used to explain if and when a transport revolution occurred in different localities. However, improved roads are just one component of declining inland transport costs. In this paper, we specific

Syftet med rapporten var att med utgångspunkt i den reviderade versionen av förskolans läroplan, Lpfö 98, belysa hur man som yrkesverksam i förskolan upplever den numera framskrivna och allt tydligare åtskillnad i uppdrag mellan förskolans olika yrkeskategorier, främst förskollärare och barnskötare. Vidare belyser rapporten förskolepersonals tankar och åsikter kring förskolechefens uppdrag: - Hur

Discussion of Swedish author Frans G. Bengtsson's classic 1920s essay on Confederate general Thomas Jonathan Jackson.

The release of dissolved silicon (DSi) from A and B horizons was investigated with leaching tests on unsaturated columns. As forest A horizons have larger biogenic Si (BSi) pools than arable lands, we compared the Si release from a forest and a cropland from the same geographical region developed on a Luvisol in Belgium and a Cambisol in Sweden. The A horizons released a quickly dissolving Si frac

Objectives The association between occupational exposure to electromagnetic fields (EMF) and the risk of uveal melanoma was investigated in a case-control study in nine European countries. Methods Incident cases of uveal melanoma and population as well as hospital controls were included and frequency matched by country, 5-year birth cohort and sex. Subjects were asked whether they had worked close

We perform calculations of the cross sections for charged-current neutrino and antineutrino scattering off Cd-116 using ten different Skyrme interactions, at energies typical of supernova neutrinos. We use the quasiparticle random-phase approximation in its charged-changing mode (pnQRPA) to construct the required nuclear wave functions for the participant initial and final states. We compare the r

The effect of body size on spatial resource competition and reproductive isolation was examined in a sister species pair of subtidal triplefin fishes (F. Tripterygiidae) in New Zealand. Ruanoho decemdigitatus and Ruanoho whero have overlapping sympatric distributions and differ in body size, attaining a total length of 12 cm and 9 cm, respectively. R. decemdigitatus was most commonly found in shel

Rapporten behandlar organisation av svensk kollektivtrafik, institutionella förutsättningar och historisk bakgrund till de omvandlings- och bevarandeprocesser som pågår idag. De avtalstyper som existerar mellan länstrafikansvariga beskrivs utförligt.

The purpose of this thesis is to examine knowledge production around globalisation and politics in Attac Sweden. As a part of the global justice movement that emerged in the 1990s, the organisation Attac Sweden related to a larger process. Attac Sweden was also central in debates about globalisation in the Swedish political context around the years 2000 and 2001. This study is based both on ethnog
