1. Spår, kropp, tid : En undersökning av den måleriska gestens materialitet 1952–1965
Sammanfattning : I Spår, kropp, tid undersöks den måleriska gestens materialitet i måleri som förknippas med abstrakt expressionism och informell konst. Ett återkommande drag i beskrivningarna av denna konst är att den sägs peka mot, eller handla om, individen eller individualitet; antingen som ett uttryck förkonstnärens inre liv genom fria, improviserade stråk på duken, eller i relation till sociala och historiska sammanhang där individualiteten har uppfattats som undertryckt av industrialismens effekter eller av kollektivistisk statligpolitik.

2. Trace metals in the atmosphere : the wet deposition of trace metals : the selenium cycle
Sammanfattning : Cd, Cu, Fe, Mn, Pb and Zn concentrations in wet deposition have been monitored in Sweden since the autumn of 1983. Concentrations of these elements are highest in southern Sweden and decrease northward. Examination of enrichment factors, relative to crustal material, indicate that the major source of Cd, Cu, Pb and Zn is anthropogenic emissions. LÄS MER
3. The trace of metals : Use, emissions and sediment load of urban heavy metals
Sammanfattning : Urban areas have been considered potential ecological hot spots for metal pollution. This is the result of three trends. First, the 20th century saw a rapid increase in the use of many materials, including metals, in the industrialized world. Second, urbanization has made towns and cities areas nodes of material flows.

4. The Evolutionary Significance of Cambrian Ecdysozoan Trace Fossils
Sammanfattning : The origin of most of the animal phyla is tied to the Cambrian explosion, a rapid diversification event that took place from about 540 million years ago. This diversification is coupled with a great number of concurrent metazoan body plan innovations such as the development of the coelom, antagonistic muscles and a through-gut. LÄS MER
5. Digital innovation management : investigating digital trace data in online communities
Sammanfattning : Firms and individuals are interacting online on an unprecedented scale. These interactions may lead to new digital products, services and practices, all of which are manifestations of digital innovation. This process relies on records users leave on various digital platforms which carry information about their activities – digital trace data. LÄS MER
