Populärvetenskaplig sammanfattning: Då man för ner en elektrisk ström i marken kommer vissa material i marken laddas upp p.g.a. att positiva och negativa joner samlar ihop sig på ytor och i trånga porkanaler. Detta kallas för polarisering och kan användas för att bestämma t.ex. vad för typ av geologiska material som finns under markytan eller vart föroreningar i marken tar vägen. Fenomenet som uppIt has been shown that surveys of Induced polarization (IP) often contain data of low quality, because it is highly sensitive against different noise sources. When measuring induced polarization, where the method uses multicore cables and continuous electrode sounding (CVES, Continuous Vertical Electrical Sounding), noise phenomena such as capacitive coupling effects have to be considered. It is p

Populärvetenskaplig sammanfattning: Brachiopodernas öde under Irevikenkatastrofen. För ungefär 430 miljoner år sedan, under tidsperioden silur, låg det område som idag är Gotland under havsytan i ett varmt, grunt hav strax söder om ekvatorn. Stora mängder kalk och lera avlagrades på havsbottnen och i havet levde bl.a. cephalopoder, trilobiter, fiskar och brachiopoder (armfotingar), det senare en bThe brachiopod fauna from parts of the Lower and Upper Visby formations on Gotland has been investigated through a combined outcrop and literature study. The strata of these formations were formed during the Ireviken Event, one of the severest identified oceanic events on Gotland, with diversity changes and extinctions among several groups of marine taxa. Seven bulk samples were collected from str

The Baltic Sea is one of the most studied seas in the world and has been in the spotlight due to its wide range of environmental problems. Human impact and climate influence on the Baltic Sea is of major concerns. This study aims to reconstruct the environment of the south east coast of the Baltic Sea and also analyze the human impact and climate influence in changing the landscape and its impact

Leaf Area Index (LAI) is quantity representing the amount of foliage in the canopy, which makes it an important parameter for analysing terrestrial ecosystems. Traditional methods of measuring LAI were done by analysing hemispherical photographs by hand and were very time consuming, requiring specific weather conditions (Jonckheere et al. 2004). Modern methods, including remote sensing, have much

According to studies, a strategically aligned purchasing strategy can increase both purchasing and business performance. The foundation for executing a strategically aligned purchasing strategy is the fact that strategic purchasing professionals inherit the relevant competencies and that organizations have tools to track purchasing professionals' performance. However, these performance- and coThe role of strategic purchasing has become increasingly important for financial success, and the portfolio of necessary skills and competencies has evolved. However, ways of assessing current competency levels for strategic purchasing development are not standardized, objective or efficient. In our thesis, we created and validated a Multiple Choice Question assessment tool for this purpo

Forskningsfrågor: Är det statistiskt signifikant att det finns en förändringar i aktieavkastning på optionens förfallodag i den underliggande aktien? har de öppna options kontrakten en påverkan på aktieavkastningen på optionens förfallodag? Syfte: Syftet med examensarbetet är att undersöka om det finns en signifikant skillnad i aktieavkastningen vid optionens förfallodag i relation till de öppna Research questions: Is there significant change in the stock return on option expiration dates in the underlying stock? Does the net open interest have an effect on the return of the underlying stock on option expiration day? Purpose: The purpose of the bachelor's thesis is to study whether there is a significant difference in the stock returns on option expiration dates in relation to the ne

In the spring of 2022 Sweden experienced several riots among counter-protesters in connection with a Danish politician's Islamophobic manifestations. A societal debate was sparked around control, police capabilities and the limits of freedom of expression. The purpose of the current study is to, based on Anne Nassauer's theory from 2019 of paths to protest violence, with the support of pre

Many cities are facing the problem of old industrial areas whose soil has been contaminated with toxic substances created by different historical activities within the area. The great unsolved environmental problems, such as: water, soil and air pollution prob- lems, and habitat loss in the Öresund region today, are a result of the industrialization era. “Reclaiming Eco-Assemblages” lays out a m

Artificial Intelligence is an expansive topic that is receiving considerable amounts of attention and funding for research, as it has the potential to have a wide-ranging effect on work, business, and society. Following from this, actors of all types, universities, companies, and others are conducting research into AI, and investigating how they can make the best use of the technology and develop

I tider av klimat- och miljökris måste vi förändra vårt sätt att leva för att bli mer motståndskraftiga och hållbara. Hållbara initiativ är viktiga för denna omställning och bör uppmuntras och stöttas av våra politiker och samhällsledare. Permakultur är ett av de lovande hållbarhetsinitiativ, som trots sin potential står inför flera hinder från kommunen för att kunna utvecklas. Den här studien undIn current times of climate crisis, we need to transform our way of living to be more resilient and sustainable. Sustainable initiatives are important for this transformation and should be encouraged and supported by our politicians and leaders. Permaculture is one of the promising sustainability initiatives, which despite its potentials, are facing multiple barriers from the municipality to devel

Investing based on environmental, social, and governmental (ESG) criteria has grown rapidly in recent years. The trend has been driven by both an increased interest in sustainability, and the fact that ESG related corporate events have been shown to influence stock prices. In tandem with this development, a number of companies has pioneered methods to quantify a firm’s ESG performance. One of thes

Eutrophication caused by nutrients such as phosphorus has become a major issue over the years. Dealing with this phenomenon is a major concern in many countries, and municipalities are establishing strict rules to cope with this problem in water bodies. However, the development of cities has a cost, and supplying the food needs of people is essential. In order to optimize agricultural lands, the u

Abstract Hydrogen as an alternative energy carrier has been up for discussion over decades. Perhaps this time, however, the political momentum and global technical context could be advantageous enough for the hydrogen economy to finally materialize. Despite investments from the EU commission up to €470 billion in renewable hydrogen, there are economical challenges in the way of decarbonisation of
