Background. Even though tobacco is one of the most preventable causes of death worldwide, it endangers more than 8 million people yearly. In this context, meta-analyses suggest that a significant part of the general Iranian population over 15 years of age smoke and that there is a need for good screening tools for smoking cravings and urges in Iran. The present study reported the translation and i

Context. Next to H and He, carbon is, together with oxygen, the most abundant element in the Universe and widely used when modelling the formation and evolution of galaxies and their stellar populations. For the Milky Way bulge, there are currently essentially no measurements of carbon in un-evolved stars, hampering our abilities to properly compare Galactic chemical evolution models to observatio

Background. School health programs need to target all aspects of physical, psychological, and social well-being. Using a slightly modified version of the COSMIN Risk of Bias checklist, we developed and conducted the first validation of the School Health Assessment Tool for Primary Schools (SHAT-PS). Method. The exploratory sequential mixed method was used in this study. In the first phase, scienti

Popular Abstract in Swedish Oxytocin-stresstestet (OST) introducerades för mer än 30 år sedan som ett kliniskt test att bedöma moderkakans reservkapacitet att tillgodose fostrets behov av syre. Vid ett OST framkallas med hjälp av oxytocininfusion ett regelbundet ”värkarbete” i avsikt att imitera värkarbetet under förlossningen. Under livmodersammandragningarna stängs blodcirkulationen i livmodern

The work presented in this thesis is mainly focused on transport processes involved in service life predictions of concrete. Two papers and three reports deal with ion transport in pore solution of concrete. One paper and one report deals with moisture transport in concrete and the remaining papers and reports deal with absorption and physical properties related to adsorption for different materia

This thesis deals with students' constructions of mathematical knowledge in the case of fractions from a radical constructivist perspective. Fractions are the first more abstracted mathematics met by students. Even if they have a rich experience of sharing and partitioning things in their everyday life dealing with fractions often give rise to difficulties in school. The thesis consists of two p

The first essay examines the outcome in a competitive private pension market characterised by adverse selection. In addition to using the private pension market, the consumers can save in a bequeathable asset. Assuming two types of agents and using the Coalition Proof Equilibrium with Private Information we show that the outcome in the private pension market may be separating or pooling. A separat

Popular Abstract in Swedish En av de stora vetenskapliga bedrifterna hittills under 2000-talet är onekligen att man efter många års arbete för första gången lyckades kartlägga (sekvensera) samtliga mänskliga gener. Det mänskliga DNA:t är lokaliserat till cellkärnan och i princip så kan man likna en cellkärna med ett kontrollrum fyllt av manualer (DNA) som talar om cellens sammansättning och hur deProteomics is expected to generate new insights into biological processes as well as identify novel biomarkers and therapeutic targets since most biological functions are transmitted through proteins. However, due to the complexity displayed by a proteome and inherent limitations associated with current methodologies, proteomic analyses often result in incomplete coverage and inconsistent measurem

The two nature reserves Benestads backar and Hagestad in Scania, southernmost Sweden, were surveyed for insect diversity during 2011 and 2012. Because current management plans for both reserves include a size expansion to increase the protective status also of adjacent areas, the aim of this survey was to derive a measure of current insect diversity in both reserves. These estimates can then be us

Popular Abstract in Swedish Kärleksdofter och varningsljud i bekämpning av nattfjärilar Jag har studerat hur populationer av skadegörande nattfjärilar kan bekämpas med miljövänliga metoder där djurens egna sinnessystem manipuleras. Liksom många andra insekter kommunicerar nattfjärilar med artspecifika doftsignaler (feromoner) vid parning. Honan avger doften i enstaka nanogram (miljarddels gram!) The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. segetum under natural and pheromone-based mating disruption conditions was monitored by harmonic radar. Individual males were equi

Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. The aim of this thesis was to develop ef

A numerical model has been used to simulate the conditions observed during the ACE-2 Hillcloud experiment and to study the processes which may be taking place. The model incorporates gas phase chemistry of sulphur and nitrogen compounds upstream of the cloud, and the interaction of aerosol, precursor trace gases and oxidants within the cloud. Gas phase and aerosol inputs to the model have been pro

Object. The aim of this study was to determine the bone lead concentration in lead smelters and reference subjects, relate them to the lead concentration in blood (B-Pb) and urine (U-Pb), and to use the measured bone lead to calculate a biological half-life for lead in bone. Method and design. The lead concentration in the second phalanx of the left index finger (bone-Pb) was determined in vivo us

Popular Abstract in Swedish Bröstcancer är i dag den vanligaste cancerformen hos kvinnor i västvärlden. I Sverige insjuknar varje år drygt 6 600 kvinnor, och detta innebär att en av tio kvinnor kommer någon gång under sin livstid att utveckla bröstcancer. Antalet nydiagnostiserade fall av bröstcancer i Sverige har under de senare åren ökat, vilket bl.a. tros bero på den ökade medelåldern i befolknIn recent time breast cancer has become the most common form of female cancer in the western world. It has been estimated that the lifetime risk of women falling ill from the disease is 10%. The number of patients diagnosed each year has been increasing steadily since the 1970s. In 2002 the number of Swedish women diagnosed with breast cancer was 6,600, constituting every third female cancer diagn

The production of ethyl esters (EE) from ethanol and cod-liver oil by an immobilised lipase in supercritical carbon dioxide (SCCO2) is described. This reaction results in a complex mixture of lipid components consisting of triglycerides, diglycerides, monoglycerides and ethyl esters. The primary goal has been to carry out enzymatic reaction and product separation simultaneously, by selectively ext

Popular Abstract in Swedish Nya möjligheter att förutsäga sjukdomsutvecklingen vid tidig ledgångsreumatism. I denna avhandling presenteras resultaten från sex studier av patienter med tidig reumatoid artrit (RA) – ledgångsreumatism. Syftet med avhandlingen var att i det tidiga sjukdomsskedet, så snart som möjligt efter diagnos, försöka skaffa information om hur sjukdomen kommer att utvecklas - om Objective: To investigate the role of magnetic resonance imaging (MRI), assessment of bone mineral density (BMD) and antibodies to citrullinated proteins (anti-CCP) in predicting radiologic outcome in patients with early rheumatoid arthritis (RA). Patients: All patients were included in the BARFOT programme (baseline). The patients had rheumatoid arthritis of recent onset with mean disease duratio

Popular Abstract in Swedish Avhandlingen utreder några av konsekvenserna av de institutionella reformer som genomfördes i Sydafrika under 1990-talet, med särskilt fokus på det nya kommunsystemet, enligt vilket varje kommun är skyldig att stimulera lokal ekonomisk utveckling i samarbete med det lokal näringslivet och andra civilsamhälleliga aktörer. Den syftar även till att utveckla den samhällsvet

Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. Treatment alternatives have therefore been developed since the early 1980s to reduce the environmental impacts of peat mining. New, efficient methods suc
