Antti Keksi (c:a 1622–1705), som levde i Övertorneås Torakankorva, anses vara den förste till namnet kände finske allmogeskalden. Hans Kvädet över vårfloden i Torneälven år 1677 har traderats till eftervärlden i fyra uppteckningar: den som gjordes för Giuseppe Acerbi under hans besök i Övertorneå 1799 (ACERBI), den som har hört till Henrik Gabriel Porthan (1739–1804) i Åbo (PORTHAN) och den som hö

Nuclear power has significantly improved performance over the last thirty years. This improvement has been based on a philosophy of control. That is, for each issue that must be managed to achieve safe performance, a pre-determined barrier must be established. In addition to the barriers that were designed into the plant, a large range of programs, processes and procedures have been developed to d

Can a more universal human rights protection be achieved through the concept of common heritage of mankind? Knowing that this concept is previously only known by its use with regard to the deep sea-bed or by the attempt the international community made for the application with reference to the moon and other celestial bodies, it might be hard to grasp that this unconventional theory can be applied

In 2000, the African Growth and Opportunity Act was signed into law in the United States, and is at present set to last until 2015. The act aimed at helping the Sub-Saharan African countries develop “through trade, not aid”. This essay studies the effect of the act on diversification of goods exported from these African countries to the United States. By analysing trade data for the period 1997-20

Abstract Rivers deliver substantial amounts of carbon (C), nitrogen (N) and phosphorus (P) to estuaries, but the effects of these inputs on the ecosystem depend on the degree to which the nutrients are bioavailable. The nutrient bioavailability is poorly known in northern regions of Scandinavia where most of the nutrients are organic. To simplify the measurements of nutrient bioavailability and

Populärvetenskaplig sammanfattning Inom vissa delar av den kemiska industrin, exempelvis läkemedelsindustrin, är det viktigt att kunna de-signa och skräddarsy organiska molekyler så att de har precis den strukturen man eftersträvar. Till sin hjälp finns det en mängd olika organiska reaktioner som kan användas för att koppla ihop och bygga molekyler på olika sätt. En molekyl med en optimerad struktPincer complexes, bicyclic complexes between a tridentate pincer ligand and a transition metal center, have been known since the 1970s and possesses a lot of advantages. They have various applications, but they are mainly used as catalysts at this point. Their desirable catalytic properties can be explained by the rigid bicyclic structure and that the σ-bond between the transition metal and the an

Popular science summary Salinity has been identified as an important factor in governing both growth and distribution of phytoplankton in marine and brackish ecosystems. In my thesis work I investigated the salinity tolerance and growth rate of the cold-water dinoflagellate Scrippsiella aff. hangoei from an Antarctic population. The work was carried out at the Department of Biology at Lund Univer

Populärvetenskaplig sammanfattning Oxidativa modifieringar av S100A9 S100A9 är ett protein i kroppen som får en förändrad struktur och funktion när det reagerar med syre. De strukturella förändringarna kallas oxidativa modiferingar. För att förstå processen skulle man kunna jämföra S100A9 med järn. När järn kommer i kontakt med syre får det en rödaktig färg och strukturen går från att vara stark tThe aim of this project was to examine how S100A9 binding to target molecules was affected by structural modifications with oxidizing agent in vitro. S100A9 was cultivated, purified and oxidative modifications were induced. The oxidative modifications where characterized with tryptohan fluorescence, Surface Plasmon Resonance technique (SPR) and MALDITOF-MS. To get access to protein to study recomb

Populärvetenskaplig sammanfattning: De skånska bokskogarna. Vad kan krypen säga? Det är mycket som påverkar våra skogar i dag. Vägar som delar upp dem i mindre delar och lantbruk och kvävenedfall som stör balansen för vad som ska växa i skogens utkanter med sin gödsling. Även trafiken påverkar genom att kväveoxiderna i avgaserna har en gödande effekt. Skogens hälsa påverkas självklart av detta, Abstract Deforestation, fragmentation and loss of biodiversity, all are elements that are common today. With this project I want to evaluate if there is a difference in functional diversity of evertebrates between beech stands of low herb and shrub type beech forest. I also want to test if there is a difference within tested areas between low herb and shrub type forests, but also if here is a dif

An experimental study was performed, aimed at finding a way to produce single crystalline powder of pure (Fe0.7Co0.3)2B with a particle size of 100-200nm. This was done with the ultimate goal of producing a hard magnetic ferrite powder for powder metallurgical production of permanent magnets. For this study, eight different compositions of iron, cobalt and boron were atomized using atomization by

Popular science summary: The Battle Against Cancer Daily, people are diagnosed with cancer, a disease that brings suffering and despair. I'm sure you have heard about chemotherapy and radiation as a way of trying to treat cancer, but it is equally important to find an effective method to quickly and reliably detect a tumor at an early stage, before it is too late. In my master's thesis,

Africa stands on the doorstep of a global information revolution that presents a range of opportu-nities. ICT has enormous potential to contribute to the development of Africa, both on an indi-vidual and societal level. The purpose of this study is to examine what effect increased ICT use has on secondary school students in Mutomo, Kenya. Furthermore the study presents a mapping of the secondary s

This master thesis explores the concept of ecosystem services, in the context of urban planning in Swedish municipalities, with the purpose of putting together a planning development tool for urban ecosystem services. The working process consisted of three steps: (1) to identify problems in the Swedish planning process, (2) to identify relevant aspects of ecosystem services and comprehensive plann

This Master Thesis has been performed at Svenska Spel with the aim to detect playing customers probability to churn, i.e. quit their gambling. The first part of the Thesis consists of some previously work done within the field, some facts about Svenska Spel and explanations of used software. The next part describes how the work has been done and the third part give the reader the theory behind the

The purpose of this paper is to investigate the possibilities of optimizing the production of paper pulp in a Conical Disc (CD) refiner for different production rates, taking into account the variables that are thought to be the most important for the production. These include three separate dilution waters, conical disc gap and flat gap. Another task is to compare the values of these variables af

Denna uppsats har haft som ändamål att undersöka om den svenska skadeförsäkringsmarknaden har karakteriserats av en premiecykel under åren 1988 – 2012. Utifrån tidigare forskning har teorier diskuterats vilka förklarar olika skäl till varför premier på försäkringsmarknaden tenderar att röra sig i cykler. Uppsatsen visar med hjälp av en autoregressiv model att den svenska marknaden, i likhet med va

This thesis describes the development of a temperature control system for optical spectroscopy experiments with rare-earth doped samples. Low temperature emission spectra were afterwards recorded for a series for Eu3+ singly doped and Ce3+, Eu3+ codoped Y2SiO5 samples. The analysis and assignment of the different energy transitions is presented. The experimental setups used in this thesis involve
