This chapter describes the utilization of recent extraction techniques such as supercritical fluid extraction, pressurized liquid extraction and microwave-assisted extraction for the determination of persistent organic pollutants in food and feed samples. These techniques have been developed because the extraction step can severely limit the entire analytical procedure. Several food crises, for ex
Reduction of energy use in buildings is fundamental for sustainable development. A computer program for the prediction of energy use in buildings was assessed by comparisons with the energy performance of existing buildings. The program was then used to evaluate the energy saving characteristics of concrete such as air tightness and heat capacity. The impacts on global environmental aspects and li
With the rapid growth of data automation, organizing and extracting valuable information from Portable Document Format (PDF) data, such as price quotation sheets, becomes an essential yet challenging task. This study aims to identify effective methods for organizing diverse price quotation documentation to enhance information retrieval from this type of document, using both unsupervised and superv
Oil is very important for today’s society and the transportation sector is almost completely dependent on this material. Unfortunately, it affects the level of greenhouse gases negatively which in turn contribute to global warming. Therefore, it is necessary to reduce greenhouse gas emissions, especially in the sectors that emit the most, as transportation sector. The European Parliament has decid
Abstract Background: As the population ageing increases, the dramatic rise in cognitive disorders such as mild cognitive impairment and dementia has become a public health priority. Mobile health technology is a unique non-pharmacological intervention for dementia and cognitive disorders. A digital platform (Support Monitoring and Reminder for Mild Dementia: SMART4MD) is created for persons with m
In this thesis, I compare the economic development between one democracy, India, and one autocracy, China. The idea is to see whether democracy has anything to do with economic development in terms of growth and welfare. To my disappointment, I have found that democracy does not have a big impact on economic development. Instead, it seems that the economical development depends on the economical p
Commercial sexual exploitation of Children and Adolescents (CSEC) is an increasing problem all over the world and especially in developing countries with growing tourist industries. In these countries CSEC and Child Sex Tourism have become two often closely connected problems. In Costa Rica there are many NGOs and governmental institutions working with these problems through prevention, attention
Dependence on fossil fuel is an issue for the many countries, it is particularly challenging for Small Island Developing States. Reliance on fossil fuel is becoming for many SIDS an economic burden. Due to the constant fluctuation in oil prices which leads to high fuel prices, high cost of living, and high electricity bills when the price of this commodity is high. This results in constant pressur
Längs Kaledonidernas östra erosionsfront finns den världskända bly- och zinkfyndigheten vid Laisvall (totalt 64 miljoner ton bruten malm) och mineraliseringen vid Granberget samt flertalet mindre malmkroppar av impregnationstyp bestående av blyglans och zinkblände som kristalliserat i klastiska bergarter. I äldre litteratur har mineraliseringsprocesserna och tidsspannet för mineralisationen diskutThe eastern Caledonian erosional front hosts the world-class Pb-Zn deposit at Laisvall (64 Mt mined) and Granberget mineralization, northern Sweden, along with several other smaller, related types of deposits consisting of impregnation mineralization of galena and sphalerite in clastic host rocks. Previous work have discussed the nature of the ore-forming processes and constraints for the timing o
Pålning är en typ av grundläggning lämplig för att grundlägga broar vid svaga markförhållanden. Att manuellt utforma en pålgrupp är en iterativ, tidskrävande process där snittkrafterna i pålarna måste verifieras för ett stort antal lastfall. Efter installationen kan pålarna dessutom ha nya positioner och kapaciteten måste verifieras igen. I detta projekt utvecklades en mjukvara för att automatiserFor bridges in weak ground conditions, piling is an appropriate type of foundation. To manually arrange the piles in a pile group is an iterative, time consuming process where the section forces in the piles must be verified for a large number of load cases. In addition, after installation, piles may have new positions and the capacity must be re-verified. In this thesis, a software was developed
This paper demonstrates the experimental validation and mechanistic analysis of the continuous cross-flow atomic layer deposition (ALD) reactor model developed in the first article of this series (Holmqvist et al., in press). A general nonlinear parameter estimation problem was formulated to identify the kinetic parameters involved in the developed ALD gassurface reaction mechanism, governing ZnO
Popular Abstract in Swedish Gliom är den vanligaste typen av hjärntumörer hos vuxna. Den mikroskopiska klassificeringen av de olika formerna av gliom är subjektiv och i vissa fall t.o.m. felaktig, vilket leder till klinisk oklarhet som kan hindra utvecklingen av terapier som riktas mot speciella egenskaper som kännetecknar speciella typer av gliom. EGFR och PDGFRA är en cellreceptor som har en cenGlioma is the most common type of primary tumor in the adult central nervous system (CNS). However, the current classification of gliomas is highly subjective and even inaccurate in some cases, which leads to clinical confusion and hinders the development of targeted therapies. EGFR and PDGFRA play crucial roles in glia development and glioma pathogenesis. In this thesis we aim to establish a glia
If we know that certain ways of making decisions are associated with real-life success, is this then how we should decide? In this paper the relationship between normative and descriptive theories of decision-making is examined. First, it is shown that the history of the decision sciences ensures that it is impossible to separate descriptive theories from normative ones. Second, recent psychologic
In this paper we present a non-linear demand system for households' joint choice of number of trips and days to spend at a destination. The approach, which facilitates welfare analysis of exogenous policy and price changes, is used empirically to study the effects of an increased CO2 tax. In particular, we focus on the effect of including substitution between households choice of the number of tri
In this thesis, the short- and long-term event study methodology are applied in order to assess whether M&As, in the pharmaceutical industry, create any abnormal return for the acquirer. The majority of the previous research finds a negative abnormal return but the short-term event study seems to generate slightly positive abnormal returns outside the U.S. There is a limited amount of research
Syftet med denna uppsats är att undersöka hur utbildning behandlas i förhållande till EU:s mervärdesskattelagstiftning. Vidare kommer denna uppsats att analysera rättsfall från EU-domstolen och hur domstolens tolkningar av begreppet utbildning relaterar till principen om neutralitet. Med detta som bakgrund kommer uppsatsen gå vidare och titta på hur Sverige har implementerat reglerna för denna typThe purpose of this thesis is to investigate how educational services is regu-lated for tax purposes under EU Law. Further, this thesis will analyse the case law considering educational services from the CJEU and consider how the Courts interpretation relates to the principle of neutrality. With the reg-ulation and case law as a basis, the thesis will then consider how the regula-tion of education
Det finns flera sätt att begränsa konkurrensen, men det finns bestämmelser i nationell och EU-rätt som spelar in när man gör det. Syftet med denna uppsats är att analysera den rättsliga ramen i svensk nationell rätt kring konkurrens mot en arbetsgivare och undersöka under vilka förutsättningar en anställd får konkurrera mot en arbetsgivare. Uppsatsen kommer också att ta en titt på hur konkurrensklThere are several ways of restricting competition, but there are regulations in national and EU- law which come into play when doing so. The purpose of this essay is to analyse the legal framework in Swedish national law concerning competition against an employer and examine the conditions under which an employee is allowed to compete against an employer. The essay will also take a look at how com
