Popular Abstract in Swedish Det försurande nedfallet över Europa har minskat kraftigt sedan 1970- och 1980-talen. Detta beror delvis på framgångsrikt arbete inom konventionen om långväga gränsöverskridande luftföroreningar (LRTAP), inom ramen för FN:s ekonomiska kommission för Europa (UNECE). Marken i många områden i Sverige och övriga Europa är fortfarande kraftigt försurad trots det minskade nedDynamic biogeochemistry models are important tools for determining the time-scales of recovery from acidification. In the review process of the 1999 UNECE LRTAP Gothenburg protocol, results from dynamic models will probably be included when determining further reductions of acidifying emissions. This thesis describes modeling of recovery from acidification using the dynamic multi-layer soil chemi

The concept of packaging logistics focuses on the synergies achieved by integrating logistics and packaging systems with the potential of increased supply chain efficiency and effectiveness, through the improvement of packaging and logistics related activities. The retail supply chain is a major consumer of different types of packaging. In Sweden alone, retailers handle approximately 1000 million

The purpose of this paper is to propose a new approach for categorizing the body of knowledge captured in the existing literature, past and present in such a way that contributions to the use side of systems development are made explicit. The new twist of this approach is that it seeks to bridge the most prevalent divides currently fragmenting the IS literature by offering an integrative classific

Gas turbines emissions, NOX in particular, have negative impact on the environment. To limit the emissions gas turbine burners are constantly improved. In this work, a fourth generation SIT (Siemens Industrial Turbomachinery) burner is studied to gain information about the formation of NOX emissions. The gas mixtures for the full burner are limited to natural gas with different nitrogen dilutions.

The aim of this three year project, which is part of the WoodWisdom-Net researchprogram, is to develop an innovative load bearing building system composed of timberglasscomposites. The structural loads applied onto these composites will be transferred to, andsupported by, the glass component, in contrary to today’s traditional solutions where glass elementsonly function as an environmental shie

Popular Abstract in Swedish All materia består av atomer. Avhandlingen du just nu läser är uppbyggd av atomer; till och med du själv är uppbyggd av atomer. En kemist är intresserad av vilka atomer som hänger ihop för att bilda molekyler och hur dessa molekyler kan sammanfogas till fasta material. Man kan likna det vid att molekylerna är en byggsten som då de sammanfogas bildar en byggnadskonstruktHow do molecules arrange themselves in a crystal? It is today not possible to definite predict the three-dimensional packing arrangement of molecules in the crystalline solid state. The aim of the work presented in this thesis has been to gain more knowledge of what principles that govern molecular packing. Platinum(II) complexes have been chosen as model system since these compounds are stable,

Miljöstraffrätten är kombinationen av miljörätt och straffrätt. Den är också kombinationen av miljöpolitik och kriminalpolitik. Straffrätten är ett mycket gammalt rättsområde, vars grundläggande principer åtminstone är 200 år gamla. Miljörätten ett rättsområde som till större delen är ett resultat av det moderna industrialiserade samhällets extrema komplexitet. Miljörätten kan med fog sägas vara e

During ascending evacuation in long stairs, there is reason to believe that factors such as fatigue, and change in human behaviour will influence the possibility of satisfactory evacuation and affect the ascending walking speed. Based on these assumption, a 2-year research project was initiated at Lund University. This paper gives a brief description of the project and highlight some initial findi

Surface force measurements, combined with ellipsometry, were performed on several colloidal liquid systems. We studied the forces between mica surfaces in presence of dilute aqueous solutions of ethylenediamine (divalent) and spermidine (trivalent) hydrochlorides. With increasing the diamine concentration the electrostatic repulsion is reduced and later it disappears completely. At equivalent tri
