We show the implications of the commonly observed age-related decline in aboveground productivity of forests, and hence forest age structure, on the carbon dynamics of European forests in response to historical changes in environmental conditions. Size-dependent carbon allocation in trees to counteract increasing hydraulic resistance with, tree height has been hypothesized to be responsible for th

When analysing new types of sewage systems, knowledge is needed on the composition of the different wastewater fractions. The computer model URWARE, developed from the model ORWARE, is intended to analyse and compare different wastewater system structures, e.g. to compare wastewater systems where urine and/or faeces are source separated with conventional wastewater systems, where the different was

The pseudoscalar meson eta(b) has been searched for in two-photon interactions at LEP II. The data sample corresponds to a total integrated luminosity of 617 pb(-1) at centre-of-mass energies ranging from 161 to 209 GeV. Upper limits at a confidence level of 95% on the product Gamma(gamma gamma) (eta(b)) x BR(eta(b)) are 190, 470 and 660 eV/c(2) for the eta(b) decaying into 4, 6 and 8 charged part

A simple and effective procedure is described for the determination of the best-fit parameters of a given model of a surface structure by analysis of low energy electron diffraction (LEED) intensities. The procedure involves a nonlinear minimisation of chi(2) for the comparison of experimental and calculated intensities as a function of the parameters of the model structure. The minimisation is ca

Caloplaca asserigena is shown to be the correct name for what has been called C. assigena. A description is provided, and it is reported to have a unique anthraquinone not previously known within Teloschistaceae. A recent find from thin twigs of Helianthemum oelandicum on the Swedish island of Öland in the Baltic is reported and its ecology is summarized.

The soot particle size distribution was studied via numerical simulation under diesel like engine conditions using a detailed kinetic soot model. Two different mathematical methods of the soot model description have been used in this work. In the first part of the work, the method of moments is presented. In addition, a so called sectional method for the soot particle size distribution function in

Anaerobic digestion of sludge has been part of the treatment plant in Malmo for many years and several projects on optimisation of the digestion process have been undertaken in full scale as well as in pilot scale. In order to facilitate a more sustainable solution in the future for waste management,solid waste organic waste is sorted out from households for anaerobic treatment in a newly built ci

Across Europe, breeding bird species are decreasing in several types of habitats. Deciduous forest specialist birds are facing a loss of habitat due to the forest management that removes important key components in the forest, e.g. dead wood. Already in Sweden three woodpecker species that are deciduous forest specialist have decreased in population: one has become locally extinct (middle spotted

This thesis seeks to answer the question of whether obligations to primary pandemic prevention and bio-risk management can be derived from the human right to health. The definition of the right to health in Article 12 of the International Covenant on Economic, Social, and Cultural Rights (ICESCR) was selected, as it is the broadest definition of the right to health in international human rights la

This thesis offers an overview of the relatively new family of Rosenbrock-Krylov numerical methods for ODEs. These methods are a further development of Rosenbrock methods, using a lower-dimension approximation of the Jacobian. The thesis gives the mathematical background to Rosenbrock-Krylov methods by first presenting Runge-Kutta methods and Rosenbrock methods, followed by the concept of Krylov s

There is a growing demand from policy makers for businesses to help close the consumer intention-action gap for sustainable product choice and strengthen the green economy. Moreover, there is increased interest from consumers in brands that are transparent about their environmental impact. This is not least the case for the focus sector of this study, food products, an industry responsible for aro

Background: The case company is a Swedish family-owned business, operating in the agri-food industry. Their philosophy is to develop, produce, and sell frozen products from the vegetable kingdom with a focus to be organic and convenient. The company has realized that the production layout and the material flow cause a lot of waste and have great potential for improvements regarding efficiency in p

Transports, and transport infrastructures enable and deliver vital societal functions in today’s society. At the same time, as sustainability becomes more and more important these sectors fail to enable the rate of change that international and national policies calls for. The electrification of the transport sector is a key driver of the future’s sustainable transport system, and the number of el

This thesis aims to investigate the different mechanisms that Chinese companies in green industries used to acquire technological capabilities and how they changed over time. The thesis also aims to examine how the geographical pattern in outbound Chinese greenfield foreign direct investment has changed over time. By examining the inbound and outbound greenfield foreign direct investment pattern i

Public participation during urban development is key for setting a project up for success and for supporting sustainable growth, but current detailed development plans available in paper-based 2D format are difficult for the public to understand. The literature has shown that the introduction of 3D visualizations can improve citizens’ understanding of a plan proposal; however, moving from static 2

The purpose of this study is to investigate if and to what extent environmental sustainability is a contributing factor in the purchase decision of craft beer among young adults. In addition, the study aims to understand how different purchasing factors are related to each other in the craft beer purchase decision. The purpose is to gain a greater understanding for the industry of small scale prod
