This paper presents the results of combined investigation of the chemical bond formation in fluorinated multiwalled carbon nanotubes (MWCNTs) with different fluorine contents (10-55 wt %) and reference compounds (highly oriented pyrolytic graphite crystals and "white" graphite fluoride) using x-ray absorption and photoelectron spectroscopy at C 1s and F 1s thresholds. Measurements were performed a

Sexual activity online may result in positive experiences for young people, or lead them to engage in risky behaviours possibly resulting in sexual assault or abuse. The aim of our study was to investigate associations between online sexual behaviours among Swedish youth and background factors as well as aspects of wellbeing. The behaviours investigated were: having sex online with a contact met o

Ghrelin is a multifunctional peptide produced predominantly in the stomach, however substantial amounts have also been found in colostrum and milk. The aim of the study was to investigate the effect of exogenous ghrelin, administered intra-gastrically, on the processes of mitosis, apoptosis, autophagy, crypt fission and changes in histometry of the small intestine mucosa in neonatal pigs, fed with

Abstract in UndeterminedThe sedimentary ancient DNA (sedaDNA) technique offers a potentially invaluable means of investigating species evolution and extinction dynamics in high-latitude environments. An implicit assumption of the sedaDNA approach is that the extracted DNA is autochthonous with the host deposit and that it has not been physically transported from older source deposits or reworked w

Interactions between iron (Fe) and arsenic (As) play a vital role in aquatic and terrestrial ecosystems influencing the reactivity and transport of arsenic. A key aspect is the effect of natural organic matter (NOM) on these interactions, and previous investigations have reported the existence of ternary As-Fe-NOM species. In this study, the reactivity of Fe, from a boreal stream water, towards As

There is general consensus among road safety researchers that the crash count is not linear with respect to the traffic volume. However, the now-preferred practice of estimating exponents on traffic volume not only results in parameters that cannot be confidently applied in other contexts, but also offers very little insight into the relationship. This paper describes a preliminary investigation o

Popular Abstract in Swedish Jag har i den här avhandlingen behandlat problemställningar inom tre olika områden inom astronomin. Det som sammanlänkar dessa är att alla innefattar dubbelstjärnor där avståndet mellan stjärnorna är litet, dvs de har en kort period. De är också alla datorsimuleringar. Jag har satt upp en modell för att betrakta de astronomiska systemen och genom numeriska metoder beräkThis thesis introduces and summarizes four papers dealing with computer simulations of astrophysical processes involving binaries. The first part gives the rational and theoretical background to these papers. In paper I and II a statistical approach to studying eclipsing binaries is described. By using population synthesis models for binaries the probabilities for eclipses are calculated for diff

The A4GALT locus encodes a glycosyltransferase that synthesizes the terminal Galα1-4Gal of the P(k)(Gb3/CD77) glycosphingolipid, important in transfusion medicine, obstetrics and pathogen susceptibility. Critical nucleotide changes in A4GALT not only abolish P(k) formation but also another Galα1-4Gal-defined antigen, P1, which belongs to the only blood group system for which the responsible locus

The aim of this study was to investigate ethnic differences in different aspects of social participation in Malmö, Sweden. The public health survey in Malmö 1994 is a cross-sectional study. A total of 5600 randomly chosen individuals aged 20–80 years were asked to complete a postal questionnaire. The participation rate was 71%. The population was divided into categories born in Sweden, Denmark/Nor

BACKGROUND: The aim of the study was to investigate the value of percutaneous fine-needle aspiration cytology (FNAC) in the diagnosis and management of liver tumours. METHODS: FNAC followed by histopathological examination was carried out in 216 patients with suspected liver tumours. The final diagnosis was primary liver cancer in 106, colorectal metastases in 51, non-colorectal metastases in 46,

This poster presents the design of a research project in its initial stages. The project Green Search investigates shaping of environmental information, including information on problems and proposed solutions, through their representation in search engine results, in social media tools, and in mobile applications dedicated to environmentally friendly living and consumption and how this is experie

Adenocarcinoma of the small intestine (ASI) is a rare disease of unknown aetiology. The glutathione S-transferase M1 (GSTM1) enzyme catalyses the detoxification of compounds involved in carcinogenesis of adenocarcinoma of the stomach, colon and lung, including constituents of tobacco smoke. We investigated a possible interaction between the lack of GSTM1 enzyme activity and the carcinogenic compou

Background: Levosimendan and volatile anesthetics have myocardial pre-conditioning effects. beta-1 adrenergic receptor antagonists may inhibit the protective effect of volatile anesthetics. No information exists as to whether this also applies to the pre-conditioning effect of levosimendan. We therefore investigated whether levosimendan added to metoprolol would demonstrate a cardioprotective effe

It is becoming increasingly clear that we need an integrated approach to understanding and encouraging transitions towards a sustainable energy system. Current overall unsustainable ‘practices’ are locked into cultural, material, institutional and infrastructural settings. This limits the scope for individual choice and action. Even when actions are taken on individual or project level, they often

Ända sedan 1800-talet har det stått klart att för den som vill utforma termodynamiska processer finns det oundvikliga kompromisser. Bland de främsta av dessa är att för en värmemotor måste man välja mellan kraft eller effektivitet: en kraftfull motor kan inte vara effektiv, och en väldigt effektiv motor kan inte vara kraftfull. Detta var länge accepterat som en oundviklig konsekvens av termodynamiWe investigate the validity of thermodynamic uncertainty relations (TURs) in a strongly correlated quantum dot system operating in the Kondo regime. TURs place fundamental bounds on the trade-off between precision and dissipation in non-equilibrium systems, and while these bounds are rigorously proven for classical stochastic dynamics, they are not guaranteed to hold in quantum-coherent, strongly

Sweden has seen a rise in firearm-related violence in recent years, and Malmö is one of three cities that has experienced a significant increase in these crimes. This study isolates the role of socioeconomic variables as determinants of firearm-related violence, exploring whether socioeconomic disadvantage independently influences the spatial distribution of these incidents in Malmö. The spatial c

Uppsatsen har analyserat beskattning av inkomster från illegala verksamheter i förhållande till rättsliga principer. Rättspraxis visar att inkomster från verk-samheter med illegala inslag kan beskattas utifrån neutralitetsprincipen och likformighetsprincipen, där alla inkomster oavsett ursprung ska beskattas. Rättspraxis på området är dock inte entydig då domstolen i andra avgöranden har kommit tiThe essay has analyzed the taxation of income from illegal activities in relation to legal principles. Case law demonstrates that income from activities with illegal elements can be taxed based on the principles of neutrality and equality, where all income, regardless of origin, should be subject to taxation. Howev-er, case law in this area is not consistent, as courts in other rulings have con-cl

The aim and purpose of this thesis is to examine the relationship between archives and cultural tourism and how people within the Swedish archives sector relate to this. Specifically, the aim is trying to find out if and how the selected archives are using (cultural)tourism and for example marketing to attract new visitors to their institutions. But also to see if it is so that the archives and th

Summary: This study is a part of the project "Lithostratigraphy and glacial dynamics during the Pomerian Phase". The objective is to solve the problems concerning the deglaciation of the south Baltic area during the last glaciation. The Polish Baltic coast is under heavy erosion from the seawaves. Steep morainic cliffs, often more than 10 meters high, offer excellent sections. A clear di

In the design of load-bearing building structures computer programs for analysis and design are frequently used. The programs are both 2D and 3D, where the latter is relatively new in the construction sector. For a 3D application, more phenomena can be taken into account, but on the other hand, the work required to build a model is more comprehensive. The purpose of this work is to investigate whe
