Åldern för jordens inre kärna är en gåta som har förbryllat forskare i många decennier. Allt från en ålder lika hög som jordens magnetfält (mellan 3,5 och 4,2 Ga) i den ena änden, ner till 0,5 Ga i den andra änden. Eftersom den inre kärnan existerar på en fullkomligt oåtkomlig plats i jordens innersta centrum, medför detta självklara svårigheter när det kommer till direkta observationer (med seismThe age of the Earth's inner core is an enigma that has puzzled scientists for many decades. Everything from an age as high as the Earth's magnetic field (between 3.5 and 4.2 Ga) at one end, down to 0.5 Ga at the other end. Since the inner core exists in a completely inaccessible place in the innermost center of the Earth, this presents obvious difficulties when it comes to direct observat

Recent scholarship has challenged the notion that digital tools alone can sustain a social movement, emphasizing instead the importance of collective identity and organizational structures. However, there is still limited understanding of how organizational structures emerge and transform in a social movement. This study argues that despite appearing chaotic or disorganized, collective actors poss

The Antonine itinerary was compiled in the early fourth century CE and is a key source to our know¬¬ledge about ancient geography and the Roman road system. However, the major research work dates more than 100 years back in time and few studies have been focussed on its overall reliability. The aim of the present work is to assess the accuracy of the distance figures in the itinerary by internal v

Autonomous cars have the potential to revolutionize private transportation by allowing occupants to utilize their travel time for other activities. Considering the new opportunities for improved productivity, as well as the increasing demand for constant digital connectivity, reconnecting with nature will be crucial for alleviating cognitive stress and promoting healing and well-being. In this the

The objective of this research is to explore returnee entrepreneurship, specifically focusing on individuals who studied abroad and started a new venture in their home country. By investigating the entrepreneurial dynamics among returnees, this study seeks to gain a deeper understanding of this specific phenomenon. To gather comprehensive and insightful data, a qualitative study with semi-structur

The aim of this project is to develop a method to detect metal objects with measurements from a magnetic sensor that is attached to a drone. This is challenging due to disturbances from currents and metal parts in the drone and the measuring equipment as well as the influence of the Earth's magnetic field. The measurements are also negatively affected by instability in the drone due to, for ex

This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. Then we set up the system and discuss the relevant approximations. Moreover analytical expressions of the c

En viss typ av immuncellsansamling i tumörer, så kallade tertiära lymfoida strukturer (TLS), hos patienter med bukspottkörtelcancer verkar inte alltid vara så gynnsamt som forskning tidigare visat. Förekomst av många TLS i tumören kunde i studien kopplas till kortare överlevnad och kan möjligen bero på att cellgiftsbehandling förändrar funktionen TLS. I denna studie studerades två typer av immuncPancreatic cancer (PC) is a devastating disease and is almost always synonymous with a poor outcome. Chemotherapy is the standard treatment and is administered in either an adjuvant or palliative setting. However, nearly all patients, regardless of treatment intent, eventually develop chemoresistance. Little is known about the events causing chemoresistance, but increased knowledge is essential fo

This essay examines the European Parliament resolution of 5 May 2022 on the impact of the war against Ukraine on women. The analysis is based on a descriptive idea analysis, which helps me map out which ideas and political actions that are adopted by the European parliament in the resolution. The essay also investigates the EU:s understanding of female exploitation and vulnerability in the Ukraini

Bilismen ökade explosionsartat under det svenska 1900-talets mitt. För att möta bilens utökade ytkrav och den olycksvåg som drabbade Sverige skulle samhället moderniseras och rekonstrueras, och det fort. Föråldrade kvarter revs, nya förorter anlades med bilen i åtanke och motorvägar såg dagens ljus. Samtidigt integrerades bilen med näringslivet, skapande köpcentra och industrier. Den fysiska miljöThe expansion of automobile usage in the middle of the 20th century gave rise to a car-centric planning, changing the Swedish society. New considerations and ideas favoured motorised planning, creating a car dependency and marginalisation of active transport like cycling. As a result, cost-benefit analyses are disregarding the benefits of cycling, making bicycle projects such as bicycle highways s

The UK government is legally bound to reach net zero greenhouse gas emissions by 2050 as part of its actions to address climate change. One prominent method of decarbonisation is carbon capture and storage (CCS), slated for deployment in two industrial clusters by the mid-2020s. Fossil fuel companies are the operator behind the rollout of this technology: given the historical reticence of these co

The thesis aims to answer the research question: To what extent was the increased Economic Policy Uncertainty during the Financial Crisis associated with the decline in Swedish exports from January 2007 to January 2010? During the 2008 Financial Crisis, Swedish trade fell by ten percentage points, slightly more than the world average. The thesis aims to investigate whether the increased EPU at the

Några utav de vanligaste orsakerna till att en brand uppkom mellan 2010 och 2020 var ”bränder som medvetet startades” samt ”bränder som startats av gnistor vid tågbromsning”. Av den totala mängden bränder som uppkom stod tågbromsning för cirka 1.1 % av dem och den anledning som stod för absolut störst andel bränder var ”bränder startade utav okänd anledning” vilket stod för 43%. KlimatförändringaForest fires can start in a variety of ways. "Fires started deliberately" and "fires started by sparks generated from a train braking" were two of the most common causes of fires between 2010 and 2020. Train braking accounted for 1.1% of all fires, whereas fires created by unknown reasons accounted for 43% of all fires. The climate is expected to change in the future, and sinc

In recent years, the construction industry has faced unprecedented challenges related to abnormal price increases on building materials, which have not been experienced since the 1970s oil crisis. These price hikes have been caused by a various of factors, including the COVID-19 pandemic, war in Europe, trade sanctions and high energy prices. Consequently, fixed-price contracts face the risk of si

Digital tools are part of the everyday lives of social workers. In the political discourse surrounding the digitalization of social services, this development tends to be described as a naturally occurring force of change. What seems less prominent is how digitalization also carries values and ideas designed within the framework of a social and political context, digital tools are consequently not

This paper analyzes the existence of market power on the Nordic electricity market between 2018-2022, and if the energy market turbulence caused by covid-19, and later deepened following the war in Ukraine affected producers' bidding behavior. Market power was tested using Cournot assumptions to see if producers withheld output strategically when demand was more inelastic. Auction data on syst

In today's world, plastic pollution has become a widespread problem with plastics in oceans, rivers and forests. The use of plastic has increased rapidly since it first was developed and that is because of its advantageous abilities. This scientific report focuses on the evaluation of two enzymes known as "autotransporter domains containing esterase" for its ability to degrade a vari
