Chilaw inlet, with the affiliated lagoon, is located on the west coast of Sri Lanka about 120 km north of the capital Colombo. Each year during the summer monsoon, which lasts from May to September, the inlet closes due to a sand spit forming across the inlet. The closure results in impeded access to the sea for the fishermen, who use the lagoon as anchorage for their boats, and in deteriorated wa

Examensarbetet har utvecklat en metod för att estimera den fraktala dimensionen från Transmissions Elektron Mikroskop (TEM) bilder av sot aggregat som skapats med hjälp av en mini-CAST sotgenerator. Det är ett underbestämt problem att estimera den fraktala dimensionen, en 3D egenskap, från 2D bilder. Lösningen är syntetiserade TEM bilder som baserats på projektioner av numeriskt simulerade aggregaIn this master’s thesis a method for estimating the fractal dimension from Transmission Electron Microscope (TEM) images of soot aggregates has been developed, and also applied to TEM images of soot sampled from a mini-CAST soot generator. The problem to estimate the fractal dimension, a 3D property, from a 2D image is undetermined. To solve this, TEM images were synthesised based on projections o

The main objective of this thesis was to identify methods for the detection of ß-lactam resistance in staphylococci, bacteria often causing nosocomial infections. Detection of ß-lactam resistance in these species is difficult due to strong regulation of genes encoding for the two main resistance mechanisms, ß-lactamase production and the penicillin-binding protein (PBP) 2?. ß-lactamase has high af

Uttrycket “övervakningssamhälle” är något som det talas om mer och mer. Vilket inte är så konstigt då många allmänna platser ofta är övervakade med antingen film eller ljudupptagning. Att kunna identifiera individer som på något sätt har brutit mot lagen eller förutse oönskade situationer är något som stärker vår säkerhet och ordningen i samhället. I många länder ses detta som helt nödvändigt och This report describes the product development process of a new product series of camera housings, adapted for modular applications. The purpose of the project was to develop a module containing a wiper, adapted for outdoor camera housings. The master thesis was performed at Axis Communications AB, a leading company in the surveillance camera industry. The camera housings of outdoor surveillance ca

Research aim and questions: The aim of this research is to investigate the way Radio Free Europe’s Romanian Language Service presented the events of December 1989 in Romania. Since Radio Free Europe/Radio Liberty was one of the most important international broadcasting institutions during the Cold War, it is relevant to see what kind of interpretation was assigned to Romania’s 1989 political and

Syftet med detta arbete är att undersöka om rullande bärighetsmätningar RWD är ett alternativ till fallviktsmätningar FWD i arbetet kring vägbärighet i vägprojekt. Bärighet beskrivs av Trafikverket som ” Den högsta last, enstaka eller ackumulerad, som kan accepteras med hänsyn till uppkomst av sprickor eller deformationer”. Det vill säga hur tunga fordon en väg eller en bro kan belastas med sThe purpose of this project is to investigate if RWD is an alternative to FWD in analysing road bearing capacity in road projects. According to the Swedish Transport Administration (Trafikverket), the definition of bearing capacity is described as “the maximum load whether single or cumulative, that can be accepted without causing cracking or deformation”. In other words, it refers to how muc

Context: The European Association of Urology Renal Cell Carcinoma (RCC) Guideline Panel has prepared evidence-based guidelines and recommendations for the management of RCC. Objective: To provide an updated RCC guideline based on standardised methodology including systematic reviews, which is robust, transparent, reproducible, and reliable. Evidence acquisition: For the 2019 update, evidence synth

Our research uses advanced technology to generate neurons from novel cell sources with the aim to extensively define the subtype and function of the generated neurons and their potential for therapeutic use in the future. For this we are using reprogramming technology in animal models or human stem cell culture system, together with electrophysiology, RNA sequencing, tracing technologies and cell

Through several decades of research, absolute paleointensity estimates have been obtained from a wide range of rocks with varying ages, covering the last 3.45 Ga years. These paleointensity data are crucial to study the past geodynamo and the geological evolution of the Earth's deep interior. However, paleointensity data are often difficult to interpret, and on-going discussions concerning the pas

Evolutionary changes in populations of microbes, such as microalgae, cannot be traced using conventional metabarcoding loci as they lack intraspecific resolution. Consequently, selection and competition processes among strains of the same species cannot be resolved without elaborate isolation, culturing, and genotyping efforts. Bamboozle, a new bioinformatic tool introduced here, scans the entire

Background: Fragrance allergens are a leading cause of contact allergy (CA). Linalool, common in cosmetics and household products, forms sensitising hydroperoxides (Lin-OOH) upon air exposure. Lin-OOH is linked to a high prevalence (3.9%–11.7%) of positive patch test results, but often gives rise to doubtful or irritant reactions. Objectives: To reassess patch test concentrations of Lin-OOH, deter

Background: Gonadal dysfunction is one of the major late complications after cancer diagnosis and treatment. The best markers of ovarian reserve in clinical practice are antral follicle count (AFC) and ovarian volume. We aimed to study the prevalence of premature ovarian insufficiency (POI) and evaluate anti-Müllerian hormone (AMH) and other serum markers for ovarian function in adult women who we

Dricksvatten är en viktig resurs i Sverige och bör vara tillgänglig varje dag. Problemet uppstår när vi måste välja mellan att bevara natursand och att säkerställa rent dricksvatten. Därför vill Sydvatten undersöka hur väl bergkross kan fungera som filtermedium. Vombverket är ett vattenverk som använder bassänginfiltration för att skapa konstgjort grundvatten. De har byggt flera dammar med filter Drinking water is a crucial resource in Sweden and must be accessible every day. A complex issue arises when we must choose between conserving natural resources like sand and ensuring clean drinking water. Therefore, Sydvatten is investigating the potential of using crushed rock as a filter medium. Vombverket is a water treatment plant that utilizes basin infiltration to produce artificial groundw

Mobile, near-source measurements are broadly used for determining δ13CH4 of individual methane (CH4) emissions sources. To answer the need for robust and comparable measurement methods, we aim to define the best practices to determine isotopic signatures of CH4 sources from atmospheric measurements, considering instrument accuracy and precision. Using the Keeling and Miller-Tans methods, we verify

Abstract Over the past decade, mass spectrometry has had an essential role in improvement of proteomics techniques. New instrument and analytical protocol developments have made mass spectrometry one of the most widely used analytical methods in quantitative proteomics. Today one of the commonly used protocols in proteomics is digestion of proteins to peptides and analysis of the peptides with li

UNLABELLED: Lay people are now able to obtain one-lead electrocardiograms (ECG) using smartwatches, which facilitates documentation of arrhythmias. The accuracy of smartwatch derived ECG intervals has not been validated in children though. Home-based monitoring of ECG intervals using a smartwatch could improve monitoring of children, e.g. when taking QTc prolonging medications. The aim of this stu

Context.Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these allow us to derive orbital and stellar parameters that are key to understanding the stellar populations of the Milky Way and to perform Galactic archaeology. Aims. We used the calibrate
