Popular Abstract in Swedish Det senaste decenniet har resistansen mot antibiotika ökat enormt och visat sig vara ett stort problem för många människor runt om hela världen. Överanvändning av antibiotika i maten, jordbruket och den farmaceutiska industrin har resulterat i en epidemi av infektioner som är resistenta mot nuvarande antibiotika och blir allt svårare att behandla. I och med att människoAntibiotic resistance is now a large threat with worldwide agreement that we will fall into a post-antibiotic era unless there is suitable treatment alternatives discovered. In recent years, chronic wounds have become a major burden on society and treatment is complicated. Honey has been widely used as a topical treatment for wounds yet there is much discourse between studies examining its effect

Microbial activity in soil is usually limited by the availability of carbon (C). Adding an easily available C source, like glucose, has therefore been a common approach to study alleviation of resource limitations. Most such studies have relied on respiration to study microbial dynamics, with few following the explicit growth response. We determined the response in bacterial and fungal growth, as

The past decade has seen a vast increase in empirical research investigating associations between social capital and health outcomes. Literature reviews reveal 'generalized trust' and 'social participation' to be the most robust of the commonly used social capital proxies, both showing positive association with health outcomes. However, this association could be confounded by unmeasured factors, s

1 The study was performed to clarify if apomorphine at the level of the rat corpus cavernosum can produce erectile responses or interfere with nerve-induced penile erection. 2 Apomorphine ( 10(-9) - 10(-4) M) exhibited a 10-fold higher potency to relax phenylephrine ( Phe)-than endothelin-1 ( ET-1)-induced contractions. Relaxant effects of apomorphine in Phe-activated corpus cavernosum did not cha

Salivary mucins are known to play important roles in the formation of oral salivary films. The aims of the present study were to investigate the behaviour of salivary mucins at solid surfaces with different wettabilities, as well as the influence of electrolyte on the adsorption behaviour. A pure preparation of human salivary MUC5B was used together with a commercial one of bovine submaxillary muc

Most nitrogen and phosphorus transported by world rivers to the oceans is associated with dissolved organic matter. However, organic matter as a potential source of N and P has hitherto been largely neglected in studies of coastal microbial food webs. We examined 50 rivers, draining a major part of the Baltic Sea watershed, with respect to summer concentrations, chemical composition, and biologica

We present the first ultraviolet and optical images of η Car and itscircumstellar Homunculus nebula, obtained with the Advanced Camera forSurveys/High Resolution Camera (ACS/HRC) on board the Hubble SpaceTelescope (HST). Compared to those at visual wavelengths, UV imagesreveal excess emission 0.1"-0.6" from the central source along the minoraxis that may emanate from the outer parts of η Car's non

drilling at Rostanga in 1997, referred to as Rostanga 1, penetrated a significant portion of the Upper Ordovician-Lower Silurian succession in this classical Lower Palaeozoic outcrop area in W-central Scania. In descending order the Upper Ordovician of the core embraces the following units (stratigraphic thickness in parenthesis): Lindegard Mudstone (27.8 m), Fjacka Shale (13.6 m), Mossen Formatio

In rats the flow of urine was diverted from the bladder over a period of 7-10 days. Active length-tension curves of muscle strips of such disused bladders did not differ from those of controls, provided lengths were related to optimum length for force development. When, however, lengths were related to length in situ the active length-tension curves were shifted to the left. The muscle strips of t

Polychlorinated biphenyls in the lower atmosphere were studied over a regional area covering approximately 11000 km(2) in southern Sweden. Sampling were performed in 1992-1993, continuously during one year, where samples from 11 sampling-sites (in all 260 samples) were analysed. PCB concentrations ranged over two order of magnitudes, 7-983 pg m(-3). Differences in PCB concentrations among the samp

Although sufficient androgen receptor (AR) function is crucial for normal male sexual differentiation, single-point mutations in the AR gene are infrequent in the two most common male congenital malformations, hypospadias and cryptorchidism. Because polymorphic CAG and GGN segments regulate AR function, we investigated whether there was any association between these polymorphisms and mentioned mal

The purpose of this thesis is to examine the effects of European integration on trade specialisation and FDI in Croatia during 1992-2002. On the basis of trade patterns, revealed comparative advantage are calculated by Balassa’s method. Further the inflow of FDI is examined to analyse if these are to be found in activities with comparative advantages or elsewhere. The analysis shows that exports h

This thesis is based on Heston and Nandi’s (2000) paper. The aim is to check how their closed-form discrete-time GARCH option pricing model performs on Swedish data, and if there are any significant changes to its performance when estimating it via maximum likelihood using the Normal- and the Student-t distribution. The model is compared with the Black-Scholes- and the ad hoc Black-Scholes model o

This thesis is written from a feminist perspective examining female asylum-seekers in international and Swedish refugee law. The question for this thesis is whether the refugee instruments are gender-sensitive and give women and men equal access to protection. The axiom of feminism is that women are subordinate to men in society and that this relationship has to be changed. The aim of feminism is

This paper analyses the causes and effects of tenure security in rural China. Using original survey data gathered in Hebei province in the summer of 2009, it begins by assessing the causes of tenure security among China’s rural landholders. It finds that within the sample, possession of a contract and faith in the legal system have the most pronounced effect on determining tenure security. Contrar
