Metan är en effektiv växthusgas som har stor betydelse för det globala klimatet. Metanemissioner från våtmarker med underliggande permafrost anses bidra väsentligt till dynamiken som styr koncentrationen av metan i atmosfären på de nordliga breddgraderna. Under nedfrysningen av marken hösten 2007 uppmättes ett stort utsläpp av metan vid en mätstation på nordöstra Grönland. Mängden metan motsvaradeMethane is an effective greenhouse gas of vital importance to global climate. Methane emissions from permafrost dominated peatlands contribute significantly to the dynamics of the high-latitude atmospheric methane concentration. During the freezing period of autumn 2007 a large methane emission peak was recorded at a peatland in northeast Greenland. The integral of this abrupt peak was equivalent

My thesis deals with the VW-Gesetz and its compatibility with the free movement of capital (Art. 56 EC). The whole topic is highly political because Volkswagen is the biggest car-producer in Niedersachsen (Lower Saxony) and provides many jobs in that area. There have been attempts to takeover the company, which have not been successful because the VW-Gesetz includes several provisions, which make

The aim of this study was to look into the discretion that the probation officer executes in cooperating with lay supervisors. In Sweden about fifty percent of the offenders sentenced to probation or on parole have lay supervisors and these supervisors are appointed by the probation officers. I asked the officers what they were looking for in a lay supervisor, certain qualifications or personaliti

This paper examines the weak form EMH regarding to the china’s stock markets and the role of WTO accession in the market efficiency. We consider A share and B share and composite index traded on the Shanghai Stock Exchange and Shenzhen Stock Exchange using daily data for 6 indexes for the period from the earliest available data to 2008/03/14. We assume WTO accession plays a positive role in the Ch

The purpose of this master thesis is to present a model that illuminates the important factors when deriving technical information from market data within a company. For companies to be able to become and stay competitive in the market, product quality is an important factor. Whilst good product quality leads to customer satisfaction and loyalty, lack of quality brings costs in service and replace

Organising knowledge in a corporate environment : a case study at the development departments of Ecophon AB The purpose of this master's thesis is to investigate how three development departments of a technical firm could organise their collection of documents and information resources to improve their management of information. Three sets of questions have been posed: 1) How does the target

Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusi

Sri Lanka has been a leading example among developing nations in the fight against poverty. Human development has been a priority of the Sri Lankan government, and many social indicators are today more in line with those of a developed country. Still poverty is a severe and widespread problem in the country. The economic growth has been under the country’s potential, and the unequal development ha

China's accession to the WTO was perceived as the West integrating the East into the international economy with market economy reforming the planned economy. The major actors, the United States (US) and the Euorpean Union (EU), with similar economic structures and ideologies were expected to cooperate and bargain the best offers from China. However, while the US adopted a confrontational appro

In this essay I examine how in seven different congregations that belong to the Church of Sweden the preparatory office is formulated in ways that differ from the form that is prescribed in the current service-book of the Church of Sweden. My purpose is to examine how and why the congregations have chosen these alternative preparatory offices. This I have tried to find out by reading the written i

Abstract Since the early 1990s the concept of ?women empowerment? has gained ground in the development discourse as a result of the acknowledgement of the marginalization of women in development strategies. Poverty is frequently given the face of a woman, making it fashionable to evolve gender sensitive development schemes based on women empowerment, which are supposed to challenge the victimizat

Human bone-marrow-derived mesenchymal stem cells (MSC) are responsible the remodeling of human tissue. However, damaged aortic valves are lack the ability to regenerate which is an active cell-mediated process. Diseased aortic valve remodeling has similarities even to bone formation. In this study, the prerequisites for cultured MSCs to undergo osteoblastic differentiation on aortic valves were ex

Popular Abstract in Swedish Den här doktorsavhandlingen handlar om vad som händer när ljus lyser genom spridande material. Det viktigaste användningsområdet är inom medicin, men även tillämpningar inom atmosfärsmätningar berörs. Metoderna som är beskrivs är dessutom så generella att de kan användas för alla typer av spridande material, till exempel olika livsmedel, papper, plast, färg och rök. I eSpectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. In order to analyze tissues to diagnose diseases, or predict doses during,

The mass production of integrated circuits for digital electronics has made CMOS technology the most frequently used IC process today. Thanks to the large production volume, CMOS has increasingly become the most cost efficient technology of choice, and the fast development of small, high speed CMOS devices has made the technology feasible for many RF applications. However, as the transistor featur

Vascular smooth muscle cells (VSMCs) in the intact vascular wall are differentiated for contraction, whereas the response to vascular injury involves transition towards a synthetic phenotype, with increased tendency for proliferation. Platelet-derived growth factor (PDGF) is thought to be important for this process. We investigated expression and functional coupling of PDGF receptors (PDGFRs) alph

Peanut (Arachis hypogaea L.) is an important oilseed crop worldwide, and peanut height has been shown to be closely related to yield, therefore a better understanding of the genetic base of plant height-related traits may allow us to have better control of crop yield. Plant height-related traits are quantitative traits that are genetically controlled by many genes, and distinct quantitive trait lo

Background: The demographic change affects the retirement age, which has been postponed in many countries. Therefore, the number of senior employees is increasing in the world. However, managers’ attitudes towards their employees’ employability affect the employees’ possibilities regarding whether they can and want to work. Objective: The aim of this study was to evaluate managers’ attitudes towar

This is presentation of a research project that investigates the learning and teaching of Swedish folk music as it unfolds across different contexts of transmission. Studies have shown that spaces for the transmission of Swedish folk music involves many aspects of social life (von Wachenfeldt, 2015, Eriksson, 2017, Eriksson, 2019). At the same time other pragmatic factors frame the transmission ta

Finansieringen av nationella vetenskapliga tidskrifter har blivit ett lömskt problem eller ett wicked problem inte bara för historia utan för humaniora i stort. Liksom andra lömska problem utmärks denna fråga av att själva problembeskrivningen är föränderlig, definitionerna undflyende samt att problemet är sammanvävt med andra komplexa problemområden. För en långsiktig lösning är det därför nödvänThe question of how to fund Swedish academic journals such as Scandia has become a wicked problem, not only for history but also for the humanities as a whole. This issue is confounded by the difficulty in terms of categorizing these journals and their funding needs and further complicated by the global movement towards open access. For the humanities, the issue of how to fund these journals is of

Amyloid formation is linked to devastating neurodegenerative diseases, motivating detailed studies of the mechanisms of amyloid formation. For Aβ, the peptide associated with Alzheimer’s disease, the mechanism and rate of aggregation have been established for a range of variants and conditions in vitro and in bodily fluids. A key outstanding question is how the relative stabilities of monomers, fi
