Popular Abstract in Swedish Bakgrund Järn (med den kemiska beteckningen Fe, från latinets ferrum) är känt för de flesta som en beståndsdel i till exempel stål. Det många inte vet är att järn är nödvändigt för liv, så som det ser ut på jorden idag. Men det finns en annan sida av myntet: järn kan nämligen också vara giftigt. Som de allra flesta känner till rostar järn i närvaro av syre och vatten.Patients suffering from the deadly progressive neurodegenerative disease Friedreich's ataxia have reduced levels of expression of the protein frataxin. Yeast frataxin has been extensively studied in vitro, and has been shown to deliver iron to heme and iron-sulfur cluster biosynthesis, as well as to oligomerize in the presence of iron. In this dissertation metal-dependent oligomerization of fratax

In this chapter we emphasize the importance of recognizing the interdependence among exchange rates, interest rates and inflation rates in measuring corporate exposure. First, several issues relating to management’s views of the macroeconomic environment, as well as the firm’s objective and structure will be discussed. These issues must be addressed before multiple regression analysis can be imple

Popular Abstract in Swedish Magsäcken är ett av kroppens största peptidhormon-producerande organ. Peptid-hormon härifrån är inte bara viktiga för att reglera olika fysiologiska funktioner i magsäcken t.ex. saltsyrasekretion och motilitet, utan också för andra funktioner i kroppen. Fortfarande vet vi mycket lite om de hormon som produceras i magsäcken. Några av de hormon man identifierat har okändaThe novel gastric hormone ghrelin was discovered by virtue of its ability to release growth hormone (GH) via interaction with the so-called GH-secretagogue receptor (GHS-R). Earlier only synthetic agents were known to bind with the GHS-R, hence, ghrelin is the first identified endogenous ligand. GHS-R occurs in the pituitary and hypothalamus but also in several peripheral tissues, suggesting the i

This study examines how States use legal arguments in cases of armed intervention and how this usage can influence the development of international law. The objective is to contribute to the understanding of the law on armed intervention by conducting a study of how States actually use legal arguments to justify or condemn armed interventions in actual cases. By assessing empirical material within

Good health is crucial for human and economic development. In particular poor health in childhood seems to be of utmost concern since it causes irreversible damage and have implications later in life. Recent research suggests globalization is a strong force affecting adult and child health outcomes. Yet, there is much unexplained variation with respect to the globalization eect on child health, in

Popular Abstract in Swedish Häri avhandlas tesen att bättre insikt i kemisk jordförorening med tjärämnen kan erhållas genom två analytiska begrepp: tillgänglighet och kemisk aktivitet. Tillgänglighet syftar på andelen av den totala mängden PAH som är tillgänglig för processer vilka sker utanför jordpartiklarna. Det andra begreppet, kemisk aktivitet, är termodynamiskt. Den kemiska aktiviteten är häThis thesis proposes the use of two concepts: accessibility and chemical activity. Accessibility describes the mass quantity of PAHs that is or can become available within a given time span and under given conditions. Chemical activity quantifies the energetic state of the PAHs that determines the potential for spontaneous physicochemical processes, such as diffusion and partitioning. Chemical act

A quite common view is that the scientific persona matters less in contemporary Western knowledge societies. Large research groups produce new scientific discoveries gathered around impersonal expert system. However, it is also well known that scientific cultures differ widely. In physics, the projects are quite impersonal, sometimes including thousands of persons. The prime example is the CERN or

Abstract in UndeterminedNorm supporting actors and structures for change.Education every day effects almost half of the population in Sweden and Nordic countries. Most research on schools and education is based within education science and there is a lack of other social science perspectives. Sociology of law with its focus on social norms, ethical values and legal norms has something different to

In this article, the author compares equity and credit investors' opinions on price formation in the equity market. More exactly, he inverts the CreditGrades model in order to back out credit-implied stock prices and stock return volatilities from credit default swap spreads for companies in the DJIA index. The credit-implied stock prices often deviate significantly from actual stock prices over t

The electronic structure of Ca in the high-temperature superconductor Bi2Sr2CaCu2O8 has been studied by x-ray-absorption spectroscopy and resonant-photoemission at the Ca L2,3 absorption edge. In the x-ray-absorption spectrum no edge structure is seen at the energy corresponding to the Ca 2p3/2 core-level binding energy, in agreement with the very low Ca density of states at the Fermi level predic

The 1s to 2π* resonances have been studied for CO strongly chemisorbed on Ni(100) and weakly chemisorbed on Cu(100) using high resolution X-ray absorption spectroscopy. We show that the spectra can be consistently described in terms of the local density of unoccupied 2π* electron states with the Fermi level obtained from corresponding X-ray photoelectron spectra. The core hole is demonstrated to i
