Development and Evaluation of an Enzyme-Based Sunscreen

Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. By introducing an enzyme-based sunscreen for daily facial use these damages may be reduced while also providing exfoliation and hydration

Risker och möjligheter med mobiltelefonen

År 2007 släpptes världens första smartphone. Bara 16 år senare har näst intill varenda människa i Sverige en mobiltelefon i deras ficka. Sakta men säkert har mobiltelefonen blivit en del av vår vardag som ett av våra mest basala behov.

Hur gammal är jordens inre kärna?

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

Flexible Organizational Structures of the Digitally Mediated Collective Actor - A Case of the Shame Movement in Georgia

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 accuracy of road distances in the Antonine itinerary

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

Detection of Metal Objects using Magnetic Sensors attached to a Drone

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

Mathematical modeling and analysis of hot carrier solar cells

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

The Effects of Chemotherapy on B Cells and T Cells in Blood and Tumor Tissue in Patients with Pancreatic Cancer – from Diagnosis to Terminal Disease

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

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

Från subjektivt till objektivt

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

Net Zero, Net Profit: An Analysis of Offshore UK Carbon Capture and Storage

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 Effect of Economic Policy Uncertainty on Swedish Exports during the 2008 Financial Crisis

How do fires affect the railway? - A Swedish study on what factors influence fire risk and how it affects railway traffic.

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

Ökade kostnader i fastprisentreprenader till följd av onormala prisökningar på material

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
