Popular Abstract in Swedish Avsaltning av havsvatten utgör en viktig källa för vattenförsörjning till befolkningen som bor vid Persiska viken, Medelhavet och Röda havet. De tre regionerna utgör ca 11,8 % av världens landyta och hade omkring 9 % av världens befolkning under 1950 och 2008, samt lika mycket enligt prognos för år 2050. Dessa områden är hemvist för 62 %, 58% och 60% av världens avsaltnSeawater desalination constitutes an important water supply to the population bordering the Arabian Gulf, the Mediterranean Sea and the Red Sea. The three regions represent about 11.8% of the world land area and the countrieshosted approximately 9% of the world population in 1950 and 2008 and are also projected to do so in 2050. The results obtained for desalination capacity in the study area were

BACKGROUND: Female sex pheromones attracting mating partners over long distances are a major determinant of reproductive isolation and speciation in Lepidoptera. Males can also produce sex pheromones but their study, particularly in butterflies, has received little attention. A detailed comparison of sex pheromones in male butterflies with those of female moths would reveal patterns of conservatio

I ett aktiebolag eller motsvarande bolagsform med begränsat ansvar för aktieägarna står aktiekapitalet i centrum. Lagstadgat krav på aktiekapital har förekommit i somliga rättsordningar. I vissa länder har kapitalkravet eftergetts. I detta arbete kommer att göras en komparativ jämförelse mellan Tysklands, Storbritanniens, Sveriges och EU:s aktiebolagsformer med avseende på minsta kapitalkravet i bIn a limited liability company or similar corporate form with limited liability for the shareholders the legal capital plays an important role. The minimum capital requirements have appeared in some jurisdictions. In some countries, the minimum capital requirement have been abolished. This work will be a comparative comparison between German, British and Swedish companies rules with focus on the m

Background-After age, sex is the most important risk factor for coronary artery disease (CAD). The mechanism through which women are protected from CAD is still largely unknown, but the observed sex difference suggests the involvement of the reproductive steroid hormone signaling system. Genetic association studies of the gene-encoding Estrogen Receptor alpha (ESR1) have shown conflicting results,

Three sets of research criteria are available for diagnosis of Alzheimer's disease in subjects with mild cognitive impairment: the International Working Group-1, International Working Group-2, and National Institute of Aging-Alzheimer Association criteria. We compared the prevalence and prognosis of Alzheimer's disease at the mild cognitive impairment stage according to these criteria. Subjects wi

As more and more applications and services in our society now depend on the Internet, it is important that dynamically deployed wireless multi hop networks are able to gain access to the Internet and other infrastructure networks and services. This thesis proposes and evaluates solutions for providing multi hop Internet Access. It investigates how ad hoc networks can be combined with wireless and

The soot particle size distribution was studied via numerical simulation under diesel like engine conditions using a detailed kinetic soot model. Two different mathematical methods of the soot model description have been used in this work. In the first part of the work, the method of moments is presented. In addition, a so called sectional method for the soot particle size distribution function in

The purpose of this project was to find estimates of the operational releases of 14C and 3H from new SMR technology that is being considered in Sweden, namely the Rolls-Royce SMR and the GE-Hitachi BWRX-300. To achieve this goal, models of the reactors of interest were made in the continuous-energy Monte-Carlo neutron and photon transport code Serpent, where the production of 14C and 3H could then

Increasingly stringent pollutant and CO2 emission standards require the car manufacturers to investigate innovative solutions to further improve the fuel economy and environmental impact of their fleets. Nowadays, NOx emissions standards are stringent for spark-ignition (SI) internal combustion engines (ICEs) and many techniques are investigated to limit these emissions. Among these, an extremely

Purpose: To assess retinal function in combination with the retinal structure in ABCA4-associated retinal degenerations. Moreover, to evaluate the possibility of predicting the natural course of these disorders. Methods: 34 patients with Stargardt disease or cone rod dystrophy carrying confirmed mutations in ABCA4 were selected from our retinitis pigmentosa (RP) register. Sequence analysis of the

Objectives: : Knowledge of the correspondence between clinical ICD diagnoses and classification criteria fulfilment is crucial to interpret studies identifying cases via ICD codes. We assessed the degree to which patients registered with ICD-10 diagnoses of psoriatic arthritis (PsA) in the Swedish National Patient Register (NPR) fulfil established PsA classification criteria. Method: Four hundred

Flexible manufacturing puts high demands on industrial automation in terms of affordable and competitive solutions and is of key importance for short-lot production typically found in small and medium sized enterprises, situations where today manual labour is extensively used despite environmental issues and harsh working conditions. Key factors in the successful introduction of new robot automati

Purpose - This paper aims to explore the electronic design of the Touch Hand: a low-cost electrically powered prosthetic hand. The hand is equipped with an array of sensors allowing for position control and haptic sensation. Pressure sensors are used on the fingertips to detect grip force. A temperature sensor placed in the fingertip is used to measure the contact temperature of objects. Investiga

According to the Global Burden of Disease study, occupational exposures to particulates, gases and fumes were responsible for 0.36 million deaths and 8.8 million disability-adjusted life years globally in 2015. This thesis focuses on two occupational groups that are at risk for developing adverse health effects from the time they spend in their working environments: cleaning workers and workers in

The World Health Organization (WHO) classification of myeloid leukaemia was revised in 2008. It incorporates newly recognized entities and emphasizes the pivotal role of cytogenetic abnormalities. The aim of this study was to evaluate the usability of the WHO classification when applied to a large population-based paediatric acute myeloid leukaemia (AML) cohort. We included children diagnosed with

Importance: The role of ω-3 polyunsaturated fatty acids for primary prevention of coronary heart disease (CHD) remains controversial. Most prior longitudinal studies evaluated self-reported consumption rather than biomarkers. Objective: To evaluate biomarkers of seafood-derived eicosapentaenoic acid (EPA; 20:5 ω-3), docosapentaenoic acid (DPA; 22:5 ω-3), and docosahexaenoic acid (DHA; 22:6 ω-3) an

Background: Transcatheter closure of secundum atrial septal defect (ASD) is nowadays the main treatment option in many centers worldwide. In symptomatic infants or in those with certain comorbidities, there is a need for early intervention. Limited data are available about the procedural safety in infants below 15 kg of weight. Methods: Retrospective review of all patients referred to our center f

Pelvic fractures may occur together with hip fractures as a result of low energy trauma. It is unclear whether they do require special attention. There are conflicting results in the literature about the prevalence of both concomitant hip and pelvic fractures as well as exclusive pelvic fractures. It has been reported that hip fractures and obturator ring fractures are mutually exclusive. To retro

The electron structure of several highly charged ions, belonging to the Mg, Ne, Mn, Fe, Co, Ga and Ge isoelectronic sequences, has been experimentally studied by means of two techniques, beam-foil spectroscopy, BFS, and the spectroscopy of laser-produced plasmas, LPP. The investigations were carried out at Lund University, LU, in 1989-90 and at the China Institute of Atomic Energy, CIAE, Beijing,

This paper reports on studies of multiple-injection strategies of gaseous fuel in a model combustion chamber and the role of jet-jet interactions on the mixing processes in the chamber using large-eddy simulation (LES). A high-pressure non-reacting gas flow injected through a jet with a nozzle diameter of 1.35 mm into a quiescent inert air environment is considered. First, we validate the method a
