We have investigated the potential impact on organic aerosol formation from biotic stress-induced emissions (SIE) of organic molecules from forests in Europe (north of lat. 45° N). Emission estimates for sesquiterpenes (SQT), methyl salicylate (MeSA) and unsaturated C17 compounds, due to different stressors, are based on experiments in the Jülich Plant Atmosphere Chamber (JPAC), combined with esti
Agricultural policies have always had a tendency to be controversial. In many cases they generate major transfers of welfare between different groups of people, and hence are favoured by some and criticised by others. They also frequently cause trouble at the international level as domestic programmes interfere with trade flows and affect the wellbeing of people in other parts of the world. In add
Popular Abstract in Swedish I Sverige och Norden har elproduktion traditionellt skett med huvudsakligen vattenkraft och kärnkraft. Detta håller dock på att förändras i takt med en allt större vindkraftsutbyggnad. Vindkraften skiljer sig i vissa avseenden från de traditionella produktionsslagen, ett av dessa är hur anslutningen till elnätet är utformad. Detta innebär att vindkraften, sedd från näteTraditionally the predominant generation has been large synchronous generators providing the system inertia. Nowadays when wind power and other non-synchronously connected units displaces this synchronous generation, the system inertia is reduced. Hence higher rate of change of frequency and larger frequency deviations are expected. This thesis deals with the impact on rate of change of frequency
Popular Abstract in Swedish I december 1990 antog riksdagen i Sverige ett miljötillägg i skollagens s k portalparagraf: "Var och en som verkar inom skolan skall främja? respekt för vår gemensamma miljö." Alltså: Alla som verkar i skolan ska nu ta sig an den nya miljötematiken i samhället. Strax därefter tillsatte regeringen en ny läroplanskommitté med ett tydligt miljöuppdrag. I juni 1992, vid FNThis thesis explores the various influence processes that take place in connection with the dawn of a new theme - the environment - in today's society. Society has declared that schools, a place designed for the intentional influence of children and youths, shall utilise the new environmental theme in its practice. It focuses on the initiation process of the environmental theme in schools from the
Three-dimensional (3D) models are widely used within the geosciences to provide scientists with conceptual and quantitative models of the earth’s subsurface. As a result, 3D geologic modelling is a growing field, such that scientific research often cannot keep up with technical advancements. Literature often shows conflicting results with respect to which interpolation algorithms produce the best
I takt med en ökad global konkurrenssituation blir företag mer fokuserade på att minimera kostnader. Företagens drivkraft att minska sitt skattetryck står i motsats till staternas vilja att bibehålla skattebasen och säkra sina intäkter. I staternas verktygslåda finns bland annat lagstiftningsmakten, men lagstiftaren kan inte alltid förutse hur en lagtext kan komma att utnyttjas. Uppsatsen behandlaIn an increasingly global competition, companies are more and more focused on minimizing costs. Businesses drive to decrease their tax burden is in contrast with the will of states to maintain the tax base and secure their income. The states have the legislative power in their toolbox, however the legislator can´t always predict how legislation will be used. This essay describes another set of too
Lag om tillfälliga begränsningar av möjligheten att få uppehållstillstånd i Sverige (benämns fortsättningsvis som den tidsbegränsade lagen) trädde i kraft 20 juli 2016 och innebär att möjligheten för alternativt skyddsbehövande att återförenas med sin familj i Sverige begränsas avsevärt. Familj till alternativt skyddsbehövande har endast rätt till uppehållstillstånd om nekandet av familjeåterförenThe temporary law of limitations regarding the possibility of being granted residence permit in Sweden (latterly known as the temporary law) took effect on July 20, 2016. It severely limits the possibility for persons eligible for subsidiary protection to be reunited with their family in Sweden.

The health and environmental impacts of food consumption are increasingly recognized as sustainability issues in developed countries. Therefore, promotion of sustainable diets is becoming more popular among governments and International NGOs. However, the question persists of how best to do this. While the determinants of behavioural change have been studied extensively, the motivations behind beh
Genom freden i Roskilde 1658 kunde Sverige tillskansa sig det tidigare danska Skåne. Fredsavtalet garanterade skåningarna rätten till, bland annat, dansk lag och tidigare danska privilegier. Statens arbete mot uniformitet i provinsen, genom att försvenska området, tog dock sakta men säkert vid, och 1683 var arbetet utfört och uniformiteten införd. Huvudsyftet med uppsatsen har varit att klargöra vIn 1658, the former Danish region of Scania was ceded to Sweden due to the Treaty of Roskilde. The treaty also guaranteed the Scanian population its right to maintain their Danish law and retain their former Danish privileges. Despite this, the state soon started to work towards uniformity between Scania and Sweden by a process known as Swedification, a process which was completed in 1683. The mai

Syftet med arbetet är att utreda hur de valda beräkningsmetoderna inverkar på dimensionerande snittmoment och dimensionerande förankringskrafter samt att undersöka hur resultaten från de olika beräkningsmetoderna varierar vid ändring av ingående parametrar. De tre beräkningsmetoder som jämförs är den analytiska metoden från SThis master thesis compares three different methods for dimensioning a sheet pile wall. The purpose is to investigate how the chosen calculation methods affect dimensioning moments and anchoring forces in a sheet pile wall and to investigate how the results from the different calculation methods vary when changing the input parameters. The three calculation methods that are compared are the analy
Fjärrvärme har en betydande roll i det svenska energisystemet där många är beroende av att systemet ska fungera optimalt. Trots den generellt höga leveranssäkerheten i dagens system är oplanerade leveransavbrott är något som sker tidvis. I Sverige började många fjärrvärmenät byggas ut i mitten av 1900-talet och mängden skador i äldre ledningar förväntas öka med tiden. Att ersätta gamla ledningar iDistrict heating plays a significant role in the Swedish energysystem where many are dependent on the district heating working optimally. The system in general has a high security of supply, but unplanned interuptions in the supply do ocasionally occur. Many of the district heating networks in Sweden began construction in the middle of the last century and some of the old pipes are expected to see
This thesis has its focus on the interaction between competition law and the public procurement regime. Since the two systems have the same objective of the creation of an internal market it is vital that the two systems reach coherence. Despite this there is now express provision on the importance to fight anti competitive behaviour in the Public Sector Directive 2004/18/EC. On March 28th 2014 th

Breast cancer is the most common type of cancer worldwide with an estimate of 2.3 million new cases in 2020, and the number one cause of cancer-related deaths in women. While survival rates are high in many high-income countries, with a five year relative survival rate of 85% and more, the respective survival rates are poor in many middle- and low-income countries, with rates as low as 12% in Kyad
Reverse electrodialysis is a membrane-based technology that utilizes the salinity gradient between two solutions (e.g. river water and seawater) to generate sustainable energy. A critical component of RED systems is the spacer, which ensures effective flow distribution and ion exchange through the membranes. Conventional spacers suffer from the shadow effect, which limits ion transport and reduces
Allergic rhinitis is a common disease affecting millions of people worldwide. Biocare Copenhagen A/S, a Danish biotechnology company decided to screen a number of probiotic lysates, with the aim to identify suitable strains with potential anti-allergic properties, that could regulate production of cytokines and divert the immune system in a regulatory or tolerant mode. People suffering from aller
One of the cleanest ways of transporting goods is at sea. However, the emissions from ships increase and with a wider knowledge about the environmental consequences caused by the emissions, requisite regulations are needed. This thesis deals with air emissions of sulphate (SOx) - and nitrogen oxides (NOx). These emissions cause negative environmental effects both by direct pollution and by forming
