The study is an update of the Second Assessment of Climate Change (BACC II) published in 2015 and focuses on the atmosphere, lan
En större mängd kvartsavslag och brända ben, upptäckta vid rekognosering (Norrbottens Museum) av hyggesberedda ytor norr om byn Sammakko, c. 40 km SO Gällivare, har tolkats att indikera ett kortvarigt använt boplatsområde. Platsen, liggande c. 100 meter norr Linaälven och i kanten av en nästan igenväxt göl, genomgick arkeologisk förundersökning sommaren 2019. Insamlat material av brända ben och trA large number of quartz fragments from knapping andburnt bone, discovered during reconnaissance (NorrbottensMuseum) of forest-cleared areas north of the villageSammakko, c. 40 km SE of Gällivare, have been interpretedto indicate a short-term used dwelling site. Th esite, located c. 100 meters north of the Linaälven Riverand at the edge of an almost overgrown pond, underwentarchaeological prelimin
Background: Instantaneous wave-free ratio (iFR) is a coronary physiology index used to assess the severity of coronary artery stenosis to guide revascularization. iFR has previously demonstrated noninferior short-term outcome compared to fractional flow reserve (FFR), but data on longer-term outcome have been lacking. Objectives: The purpose of this study was to investigate the prespecified 5-year
Many animals use visual signals to navigate through their environment, and among the top navigators in the animal world we find insects. Even though their brains are incredibly small, insects are able to find their way using, for example, a strategy known as path integration. By updating the distance and direction travelled the insect is able to find the way back to its point of origin along a str
Barn i svenska förskolor utsätts för höga ljudnivåer som kan orsaka hörselskador och röstrelaterade problem bland både lärare och elever. Detta på grund av att de behöver höja rösten för att göra sig hörda i en bullrig miljö. På grund av detta är det av intresse att på något sätt kunna förutse ljudmiljön i just förskolor. Detta kan exempelvis göras genom att falta binaurala inspelningar av förskolChildren in Swedish preschools are exposed to high noise levels that can cause hearing damage or voice related problems among both teachers and students, this since they have to raise their voice in order to make themselves heard in a noisy environment. Because of this it is of interest to be able to predict the sound environment in preschools. A way to do this is through convolving binaural recor
Among cast materials, grey cast iron and ductile iron makes up about three quarters of all cast parts. This makes the manufacturing and machining of grey cast iron an important economical factor for the automotive industry. In a world with finite resources and growing concerns for the environment the importance and interest in recycling grows larger. This has led the Volvo Trucks Corporation to u
The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. Human activities' continuous greenhouse gas emission has contributed to global climate change, which has caused some atmos
Complement inhibitors in cancer - supporting the enemy Cancer is one of the leading causes of deaths worldwide. In 2018 alone, 9.6 million deaths were due to cancer. Cancer cells themselves and the sites they colonize play an important role in cancer growth, progression and response to treatment. There are many factors that exist in body areas affected by cancer including components of the immune
Den östra delen av Kaapvaalkratonen i södra Afrika är rikt på flera generationer av mafiska gångar med olika riktningar. Där finns tre gångsvärmar som tidigare undersökts och som tillsammans bildar ett radierande mönster med ett gemensamt fokus i Bushveld-komplexets östra del. De nordostliga och ostliga grenarna av denna svärm består av diabasgångar som blivit daterade till ca 2660, 2685 och 2700 Numerous mafic dykes of different generations and trends intrude the eastern part of the Kaapvaal Cra-ton. On eastern Kaapvaal, there are three previously investigated dyke swarms that appear to radiate out from the eastern lobe of the Bushveld Complex. The NE- and E trending branches comprise dykes dated at ca. 2660 Ma, 2685 Ma and 2700 Ma (Olsson et al. 2011). Further south, a NE-trending swarm,
Ett regelverk i förändring. De särskilt inrättade reglerna för beskattning av delägare i fåmansföretag för kapitalvinst eller utdelning är unika på många sätt. De första tjugofem åren ändrades reglerna tjugotre gånger, nästan en gång per år. Främst beroende på bakomliggande svängningar i politiken. I fåmansföretagen finns det som huvudregel inget reellt tvåpartsförhållande då delägaren styr bolageThe specially made rules for taxation of partners in close companies regarding dividend are unique in many ways. During the first twenty-five years these rules changed twenty-three times, almost once a year. This occurrence was mainly due to underlining political balance between purposes. In these close companies there’s often no real two-party relationship as the partner oversees the company. Thi
Epithelial ovarian carcinoma is a gynecological cancer with the highest death incidence worldwide. It is treated with surgery and chemotherapeutic drugs: platinum or taxane. However, around 80% of patients have disease progression into more aggressive and chemoresistant cancer. Mitochondria are structures inside both normal and cancer cells which are central to the cell´s metabolism by supplying e
Popular science summary: Understanding the bacterial cytoskeleton The bacterial cytoskeleton was discovered not too long ago. Since its discovery, it has been a source of information and understanding of how this essential cellular system is established and maintained. The cytoskeleton allows for subcellular organization, which is the key behind many cellular functions. One such function is pola
Popular science The carbon balance of the forest ecosystems is determined by the uptake and release of carbon. Forests take up carbon dioxide (CO2) by photosynthesis and release by respiration. One part of the assimilated carbon is respired back to the atmosphere by vegetation. The other part is respired by soil microbes which decompose organic material in soil. The microbial respiration is contro
Åderförkalkning - En undersökning av plackstabilitet Åderförkalkning, eller ateroskleros, är en kärlsjukdom som orsakar förträngningar i kroppens artärer. Hjärt- och kärlsjukdomar är de vanligaste orsakerna till dödsfall globalt - det uppskattas att 17,5 miljoner människor gick bort till följd av dem 2012, vilket motsvarar 31 % av alla dödsfall det året. Det saknas därmed inte anledningar till atAtherosclerosis is a chronic disease of arteries. Cardiovascular diseases, of which atherosclerosis is an underlying mechanism, are the most common causes of death globally. The disease is characterised by lipids having penetrated the intima of the artery wall, accompanied by inflammation, fibrosis and endothelial hyperplasia. Accumulated cells, lipids, connective-tissue elements and debris from t

Grey Cast iron is an Iron Carbon alloy and is known for its wide range of applications in manufacturing industry. It contains inclusions such as Manganese, silicon, nickel, vanadium and copper. Traces of impurities such as sulphur and phosphorous are also present which is one of the factors affecting Machinability leading to unpredictable process behavior. This Master’s degree thesis is an Indust
Solar energy plays a vital role in the transition to a greener global energy supply. As a decentralized energy source, the expansion of solar energy is not driven by energy suppliers and government as in traditional energy sources but is proliferating through the market through a variety of business propositions. Germany has, for a long time, been a pioneer in the field of solar. The country was t
A quarter of the Earth’s vegetated surfaces have seen an extension in the fire weather season since 1979, with areas in the Middle East still seeing an increase in burned areas although the global average burned area is decreasing. As fires emit 1.6-2.8 Pg carbon annually, the link between fires and climate has been vigorously studied in western and tropical areas, leaving a research gap for arid
Since the 1970s, the practice of conscripting, enlisting or recruiting children into armed groups or forces has become increasingly common, and many children are used for various tasks in conflicts around the globe. Children are easily persuaded or forced into such armed groups or forces, and they suffer great harm from exposure to violence. Girls are generally recruited in the same manner as boys
The purpose of this thesis is two-fold: implement and evaluate a method, the Fast Correlation-Based Filter (FCBF) by Yu et al., for feature selection applied on a meteorological data set consisting of 19 weather variables from 606 locations in Scandinavia, and investigate whether geography can be exploited in the search for relevant features. Four areas are chosen as target areas where load predic
