Is världen över smälter till följd av temperaturökningen som sker på jorden. Glaciärer retirerar och isen tunnas ut vid polarområdena. Vid Arktis har isen studerats under hundratals år men det var inte förrän på 1970-talet som havsisens utbredning kunde kartläggas ordentligt med hjälp av fjärranalys. Passiv mikrovågsradiometri är den vanligaste metoden för att mäta havsisens utbredning. Trenderna All over the world ice is melting as a result of the increased temperature. The sea ice at the poles is getting thinner and glaciers are retreating. The Arctic has been studied during hundreds of years but it was not until the 1970’s the sea ice extent could be surveyed properly with remote sensing. The most common method to investigate the sea ice extent is with passive microwave satellite sensor

Abstract Authors: Max Elmgren and Magnus Svensson Title: Fairness of assessment or individual assessment – a study of local guidelines‟ implementation in social service. [translated title] Supervisor: Susanna Johansson Assessor: Elizabeth Martinell Barfoed The purpose of this study was to explore how local guidelines are implemented in the assessment of social welfare in two different social welfa

Teachers’ experiences of school leadership behaviour and the social contexts in which these have taken place interest me. I aim to identify and understand what Swedish secondary school language teachers’ reflections are on what they require in terms of leadership from their principals in different contexts in order to gain personal job satisfaction. The objective is that this research can then fun

Building in a manner that minimizes environmental impact has become a major part of the construction industry. Despite increased knowledge in this area the development is moving slowly. The purpose of this thesis is to give the reader an idea of the approach to green construction of civil engineering. The definition of a green tender is defined by the people who have been interviewed. The question

Accessibility is something often taken for granted in our society, but it is a necessity for people with disabilities. Railway stations are a public place and are often a connecting point for several modes of transport. Design of railway stations in terms of accessibility for persons with disabilities is governed by several national and international governing documents. The purpose of this thesis

This report is a result of a Master thesis that was carried out at Dresser Wayne AB and at the Division of Machine Design at the Department of Design Sciences LTH. The thesis was written as a product development report and essentially follows the method described by Ulrich and Eppinger found in the publication Product Design and Development. The objective of the Master Thesis was to design and bui

This thesis is an analysis of five IKEA commercials that were produced for different contexts and different target groups: one that was played in many countries, one for North America, one for Australia, one for Poland and one for Italy. These commercials were analysed on three different levels, with every level of analysis based on the findings on the preceding level. The first level is an analys

This thesis is about combining three archaeological themes; the interpretation of grave contexts, social identities and Iron Age jewellery has been given a place here. The aim was to discern which meanings and functions that can be connected to Migration Period bracteates in graves, and if so how they manifest in the context. Bracteates, small pendants dated to the Migration and Vendel periods, ha

With the constant downscaling of transistors, silicon as a production material is falling out of favour because of increasing power consumption when the size of devices becomes smaller. Compound materials from group III-V in the table of elements are promising candidates to replace silicon. The aim of this work was to study current-voltage characteristics of a MOS capacitor made of the III-V compo

The geo-electrical survey (resistivity and induced polarization) with different settings, arrangements, time base, spreads and waveforms (50% and 100% duty cycle waveform) was carried out over the Liikavaara depo-sit, near the Aitik mine, in northern Sweden and all the measured data was inverted in two different softwares: Res2Dinv and AarhusInv. Surveys of induced polarization (IP) often contain

Abstract The aim of this dissertation was to study those directly affected by the 2010 law on Coordinated Individual Plan (Samordnad Individuell Plan, SIP). How the service users experienced the implementation of SIP and how the plan came to affect them in their day-to-day work. The dissertation takes its point of departure in a discussion concerning the critique of psychiatric care, the well bei

On 22 January 2015, the ECB finally announced its expanded asset repurchase programme, better known as quantitative easing (ECB, 2015c). In this thesis, we are examining the effect of this announcement on sovereign bond yields in the Eurozone using the event study methodology and by time series forecasting (ARMA). We are particularly interested to see if there have been some abnormal variations (i

Background: Detecting and monitoring monoclonal free light immunoglobulin chains in serum is important for managing patients with B-cell neoplasms. Established methods have relied on immunochemistry, with monoclonality determined through an abnormal ratio of free kappa and lambda chains and an increased concentration of the involved chain. This indirect approach has limitations. Mass spectrometric

Multiple myeloma (MM) is the second most common hematological malignancy, characterized by a clonal expansion of malignant plasma cells in bone marrow. Monoclonal gammopathy of undetermined significance (MGUS) is the premalignant condition of MM. The tumor microenvironment is thought to influence the progression from premalignant conditions. Myeloid-derived suppressor cells (MDSCs) are a heterogen

AIMS: Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVC) is characterized by ventricular arrhythmias (VAs) and sudden cardiac death (SCD). We aimed to develop a model for individualized prediction of incident VA/SCD in ARVC patients. METHODS AND RESULTS: Five hundred and twenty-eight patients with a definite diagnosis and no history of sustained VAs/SCD at baseline, aged 38.2 ± 15.5 

The valorization of lignin is being increasingly recognized as crucial to improve the economic viability of integrated biorefineries. Because of its inherent heterogeneity and recalcitrance, lignin has been treated as a waste product in the pulp and paper industry, but new technologies are now being explored to transform lignin into a sustainable resource and enhance its value chain. In the presen

The crystalline lens of the vertebrate eye grows throughout life. This growth may be enormous in fish, while the lens must be functional from larva to adult. During growth, the fiber cells of the lens must increase the concentration of specific proteins (crystallins) in the cytoplasm to increase refractive index. However, the bulk of the fiber cells in a vertebrate lens are denucleated and have no

Individuals with immigrant background generally perform less well in school than non-immigrants. Performing well in school may decrease the risk of substance use disorder (SUD). We investigated whether higher school performance is associated with a decreased risk of SUD in early adulthood among immigrants and non-immigrants and whether subsequent educational attainment and employment status partly

Objective: Classification criteria for early-stage symptomatic knee osteoarthritis (EsSKOA) should discriminate individuals with EsSKOA from those with other causes of knee symptoms. We sought to identify conditions in the differential diagnosis of EsSKOA in adults with knee symptoms. Design: We conducted an online survey of clinicians. Those consulting monthly on at least five people with undiagn
