How Stellar Tides Affect Planet Evolution

Som de flesta av oss vet så kretsar planeter i elliptiska banor runt stjärnor. Vissa planeter som ligger väldigt nära de stjärnor som de kretsar får uppleva visa effekter som inte märkbart påverkar de planeterna i omloppsbana längre bort. Dessa effekter uppkommer ur så kallade tidvattenskrafter som härstammar från det faktum att gravitationskrafter beror väldigt mycket på avstånd mellan objekt. DePlanets that orbit their host star closely experience tidal forces due to the strength of gravity not being uniform all over the planet. This leads to effects such as tidal spin synchronization, tidal eccentricity damping and tidal semi-major axis damping. This project aims to study how the time scales for these phenomena are affected by the planetary parameters such as mass, radius and the tidal

Gång- och cykelbro i rostfritt duplexstål: En utredning genom livscykelanalys, kostnadsanalys och konstruktionstekniska beräkningar

Rostfritt duplexstål är ett konstruktionsmaterial som skulle kunna tänkas vara konkurrenskraftigt i förhållande till konventionella material inom brobyggnad med tanke på dess höga hållfasthet, marginella underhållsbehov och möjlighet till återvinning. Hittills har det dock inte använts i någon större utsträckning inom brobyggnad framför allt på grund av dess högre kostnad i förhållande till traditDuplex stainless steel is a construction material that could possibly prove competitive in relation to conventional materials in bridge design, given its high strength, marginal maintenance needs and the possibility of recycling. To date, however, it has not been used to any great extent in bridge constructions, mainly because of its higher cost in relation to traditional carbon steel. In this stu

Hållbart företagande - moralisk eller rättslig skyldighet?

I takt med det ökade mediala fokus på globalisering och klimathot ställs nya krav på samhället och på att företag ska ta ett moraliskt ansvar för hållbarhetsfrågor. Frågan är om hållbart företagande kan anses förenligt med gällande rätt. Vinstsyftet i 3 kap. 3 § ABL är det grundläggande kriteriet för bolagsledningens beslutsfattande och innebär indirekt att ledningen inte får prioritera till exemThe increased media focus on globalization and climate change has brought new demands from society, which has led to more companies taking moral responsibility for sustainability issues. The question is whether sustainable business can be considered compatible with applicable law. The profit objective in Chapter 3 § 3 in the Swedish Companies Act (”Aktiebolagslagen” [2005:551], ”ABL”) is the fun

En närstående rättighet för presspublikationer på den digitala inre marknaden - En studie av artikel 15 i direktiv (EU) 2019/790 om upphovsrätt och närstående rättigheter på den digitala inre marknaden

I dagens digitaliserade samhälle möter utgivare och publicister av traditionellt tryckt media stora ekonomiska motgångar vid försäljningen av exempelvis nyhetstidningar eller andra tidskrifter. Således har majoriteten av utläggare idag gjort sina publikationer tillgängliga för läsare online. De digitala intäkterna lyckas dock inte väga upp för de förluster utgivarna lider av den nedåtgående försälIn today's digitized society, publishers of legacy printed media face major financial hardships in the sale of newspapers and other magazines. Thus, most publishers today have made their publications available to readers online. However, digital revenues do not make up for the losses that the publishers suffer from the decreasing sales of printed media. This can in part be attributed to the fa
