Populärvetenskaplig sammanfattning Spektroskopi handlar om teoretiska modeller och experiment där man observerar ljus som har växelverkat med materia. Spektroskopiska metoder används inom många olika ämnesområden som exempelvis kemi, fysik och biologi. Ett jordnära exempel på tillämpad spektroskopi är människans öga. Reflekterat ljus från olika föremål samlas in av linsen i ögat, avbildas på näthiIn this thesis a novel spectroscopic method consisting of a combination of frequency domain photon migration (FPDM) and gas in scattering media absorption spectroscopy (GASMAS) is developed, for assessment of the mean optical path length and gas absorption in porous media. The system stability is experimentally investigated and measurements are performed on balsa and pine wood to evaluate the rela

The purpose of this thesis is to provide insight into the recruitment and selection processes of high-tech companies in China and to advice returning Chinese overseas students on these recruitment and selection processes. We collected empirical data from respondents by using semi-structured interviews for the following qualitative analysis. Interview guide, selection of respondents, conduction of

Property rights systems and their relationship to the informal spaces are a contested and highly relevant part of contemporary development discourse. This study explores the reproduction of the concept of the informal in urban space. The central problematic of this study then departs by asking in what ways does the debate on property rights and the informal economy emerge as a representation of sp

A forward recursive estimation method is used to examine stock market data on unit root against explosive behavior as an indication of financial exuberance. Through specific dividend-stock pricing modeling, the recursive implementation of a right-tailed ADF test allows for directly testing the price index series on explosive behavior and its corresponding dividend series on non-explosive behavior.

Prior research indicates that the increase in help towards 1 identified victim (identifiable victim effect) is partly driven by affective reasoning. When negative affective information is salient, help towards victims that can be helped decline, an effect known as pseudoinefficacy. However, the affective component has not been clearly defined, and help efforts has been used interchangeably with me

Sustainability Science (SS) is known for aspiration to support societies towards ecologically sound trajectories – a fabulously reflexive, ultimately critical and deeply self-aware field with a diverse community of highly skilled and creative researchers of noble goals, rigorous training and active engagement with ‘real life’ (so we claim, or at least aspire for). We try hard to alter extinction o

The ecological footprint of Denmark has been rising since (and likely even before) 1961, which signifies an unsustainable living by the Danish population. Global footprint reports show Denmark as one of many countries on earth which has exceeded its biocapacity (BC), which means natural resource consumption in Denmark is faster than the land’s regenerative capacity. The residents of Denmark are co

It is well-known that long memory and regime switching in the first moment of a stochastic process are easily confused. But the relation between long memory in the second moment and regime switching in the second moment is less well understood. We perform a simulation study in which we assess the possibility to distinguish the two properties in the case that data with long memory in the second mom

Abstract The long-term aim of this project was to develop synbiotic drinks presenting food supplements with beneficial effects on human health. A synbiotic consists of a combination of probiotic bacteria and one or more prebiotics. For the part of the project that was covered by this Master thesis, a probiotic strain, Lactobacillus plantarum F44 and a prebiotic galactooligosaccharide (GOS) were t

Human development index (HDI) is a summary measure used around the world that indicates whether a country is developed, still developing, or undeveloped. HDI incorporates the main factors of human life such as health, education and income. Deprivation in these areas of human life is measured by calculating human poverty index (HPI). The purpose of this thesis is to find the human development index

Electrification of commercial heavy vehicles has led to the offer of different electric drive-based powertrain architectures, most of them with the adaptation of the diesel engine based architecture. Due to the limited driving range possible, optimal configuration of the powertrain becomes a vital task with the battery as the energy source, which also takes a significant portion of payload capacit

BackgroundLiver metastases are a common consequence of colorectal cancer. When feasible, surgical resection is first-line treatment. Synchronous disease can be treated with different strategies. Traditionally, the primary tumour is resected first followed by resection of the liver metastases (bowel-first). The other option, which is increasing, is the liver-first strategy, where resection of the l

PMCA4 is a critical regulator of Ca2+ homeostasis in mammalian cells. While its biological and prognostic relevance in several cancer types has already been demonstrated, only preclinical investigations suggested a metastasis suppressor function in melanoma. Therefore, we studied the expression pattern of PMCA4 in human skin, nevus, as well as in primary and metastatic melanoma using immunohistoch

Incumbent firms face growing pressure to transform their business towards sustainability. However, business models for sustainability (BMfS) and circularity are grounded in fundamentally different institutional logic which, for incumbents, creates tensions with existing business models, structures and routines. How organizations manage tensions from conflicting logics is explored comprehensively i

The aim of our study was to test the hypothesis that administration of Regenerating islet-derived protein 3α (Reg3α), a protein described as having protective effects against oxidative stress and anti-inflammatory activity, could participate in the control of glucose homeostasis and potentially be a new target of interest in the treatment of type 2 diabetes. To that end the recombinant human Reg3α

C4b-binding protein (C4BP) regulates the classical pathway C3-convertase of the complement system. Human C4BP is composed of seven identical subunits (alpha-chains) and one unique one (beta-chain). Both types of chains contain homologous repeats called complement control proteins (CCPs); the alpha-chain contains eight CCPs and the beta-chain three. Each alpha-chain contains a binding site for C4b
