Aviation is known to be safe, partly due to highly specialized pilots who undergo extensive training to fulfill and maintain their function at the sharp end. More demands are placed on the pilots as complexity continues to grow in aviation. This is due to more technology, more rules of compliance, more diversity in operations, and less time to do it all in the aggressive competitive world of avia
The aim of this paper is to examine how the covid-19 pandemic and the restrictions around have effected domestic violence against women in Sweden. The year 2020 has been affected hard by the coronavirus spreading throughout the world. Alot of nations applied a lockdown strategy to fight the spread of the virus. Sweden choosed to handle things differently and let the government give out recommendat
The momentum effect is a persistent and stable phenomenon, achieving very high abnormal returns, which could not yet be explained by conventional pricing models. However, this very high returns are punctuated by extreme strategy crashes leading to high losses, for which investors need decades to recover from. This makes momentum less attractive for risk-averse investors and motivates an appropriat
Aviation in Europe has undergone an enormous change from national rulemaking to common European rulemaking. Behind this change is the European Union’s decision to delegate some policy implementation functions to decentralised agencies. The European Union Aviation Safety Agency (EASA) is one of these EU agencies and has specific authorisation to implement decisions that directly impact individuals,
In nature, for example through mechanical degradation (e.g., plastic waste in the sea) and through the exposure to UV-radiation, plastics can degrade to microplastics and eventually to even smaller plastic nanoparticles. Studies performed under laboratory conditions have shown that plastic nanoparticles can accumulate in the liver and the brain of fishes, hence plastic nanoparticles can cause brai
I dagens samhälle finns det en stor drivkraft att verka för mer hållbara alternativ till de fossila material som varit allmänt förekommande i flera områden av bland annat energiproduktion. Den begränsade mängden kombinerat med de klimatförändrande effekterna av växthusgasutsläpp skapar inte bara en efterfrågan utan gör det ytterst nödvändigt att hitta nya vägar för samhällsutveckling. En sektor soAs concerns grow ever larger about the negative effects of CO2 emissions, the use of hydrogen gas as an alternative to fossil fuels is becoming a more attractive objective. This however, requires practical ways of storing and transporting a highly flammable gas and is generally not compatible with much of the existing infrastructure. One proposed solution to this problem is implementation of liqui
This thesis examines the Global Britain discourse and its articulation in the Integrated Review, a foreign policy paper, published by the British Government in March 2021. Global Britain is not a new phenomenon but an imperial legacy. The study highlights this legacy and underlines what British foreign policy focuses on in the future post-Brexit world. Faircloughian critical discourse analysis and
In 5G communications, Non-terrestrial Network (NTN) is envisioned to complement Terrestrial Network (TN) to increase network availability, scalability and continuity. Positioning of User Equipment (UE) is critical for the operation of NTN. Currently, NTN uses Global Navigation Satellite System (GNSS) for positioning. However, the use of GNSS to complement NTN operation has some drawbacks such as h
Packaging of fast food and take-out food involves a significant amount of material that ends up in landfills, recycling and litter. This is because the packaging is designed only for a single-use. There’s no future in single-use products and that includes single-use takeaway packaging. Influenced by the negative image of plastic, individual restaurants and food vendors are increasingly switching
Kristina Sandbergs trilogi om hemmafrun Majs liv med böckerna Att föda ett barn (2010), Sörja för de sina (2012) och Liv till varje pris (2014) är ett stycke episk diskbänksrealism som samtidigt formmedvetet leker med prosakonstens konventioner i syfte att skapa rytm. Denna masteruppsats undersöker, genom en fyrdelad analys, rytmskapande på flera olika nivåer i text. Uppsatsen undersöker trilogins
Background Scania’s production unit in Oskarshamn manufactures and supplies truck cabs to the European market. In order to remain competitive, it is necessary for the company to re-evaluate its competencies and technologies. Thus, it is of great interest for Scania to investigate what value newly acquired technology can provide to the company and its operations. Problem description As a part of S
Trots FN:s 17 globala mål och Sveriges nationella mål om ett fossilfritt Sverige 2045 är bilen fortfarande det vanligaste transportmedlet i Sveriges största städer. Cykeln är ett miljövänligt och platseffektivt alternativ till bilen och många europeiska länder satsar man på att främja cykling idag. Cykelgatan, som är en trafikutformning som har testats i Sverige sedan 2007, syftar bland annat tillDespite the UN’s 17 global goals and Sweden’s national goal of a fossil-free Sweden 2045, the car is still the most common means of transport for Sweden's largest cities. The bicycle is an environmentally friendly and space-efficient alternative to the car and many European countries are investing in promoting cycling today. The bicycle street, which is a traffic design that has been tested in
Föroreningar i dagvatten är en stor bidragande faktor till dålig vattenkvalitet i sjöar och vattendrag, och en stor andel av dessa föroreningar generas av mänskliga aktiviteter. Dagvattens föroreningssammansättning varierar kraftigt beroende på vilka ytor vattnet kommer i kontakt med. I ett jordbruksdominerat landskap transporteras stora mängder näringsämnen via ytavrinning och dränering till närl
Based on the increasing rate of globalisation resulting in a more diverse workforce, the purpose of this study is to investigate the relationship between diversity and job satisfaction in medical R&D teams. Determining such a relationship is highly valuable for managers of R&D teams to ensure the best possible output from the team, reducing turnover and keeping existing talent within the t
I Sverige planeras det för höghastighetsjärnvägar, med högre hastigheter än vad som används idag, för att binda samman landets tre storstadsregioner. I samband med detta krävs ett utvecklingsarbete av olika järnvägstekniska lösningar där kontaktledning är ett av områdena som utvecklas för att möta högre hastighetskrav. Detta examensarbete syftar på att analysera och jämföra olika kontaktledningssySweden is planning for highspeed railway with higher speed than used today between the country's three large metropolitan regions: Stockholm, Gothenburg and Malmö. In connection with this, various technical solutions, where the overhead catenary system is one area, must be developed further to meet higher speed requirements. This thesis aims to analyse and compare different catenary systems ag
I många sammanhang är man intresserad av lösningar till ekvationer eller den geometriska strukturen av lösningarna till en mängd ekvationer, speciellt då det inte går att ange dem explicit. Även enkla exempel av detta finns: ekvationen $x^2+y^2=1$ definierar en cirkel, men det går inte att beskriva alla reella tal som löser den utan att man använder transcendentala funktioner. Algebraisk geometri We provide an introduction to scheme-theoretic algebraic geometry, which studies spaces that are in essence locally solutions to systems of polynomial equations, and prove the weak Mordell-Weil theorem. The weak Mordell-Weil theorem states that for an elliptic curve $E$ over a number field $K$, the quotient $E(K)/mE(K)$ is finite for all $m\geq 2$. The proof is adapted from a proof in the language
Klimatförändringar orsakade av människans aktivitet har de senaste åren varit i fokus runt om i hela världen. Bygg- och anläggningssektor som står för en femtedel av växthusgasutsläpp jobbar ständigt för att hitta hållbara och ekonomiskt lönsamma metoder för att uppnå uppsatta klimatmål. Inom asfaltsindustrin har biobaserade bindemedel den senaste tiden börjat testas för att undersöka potentialen Bio-based binders have recently been introduced to reduce the dependence on fossil raw materials, which bitumen is produced of. Measurements with dynamic shear rheometer (DSR) and rotational viscometer (RVB) were performed on mixtures with bitumen and two different types of bio-based binders, namely Lignin 1 and Lignin 2. Parameters like softness point, viscosity and parameters used to evaluate ru
