The CFA Franc Zone in Northern Africa is a currency union where the currency has been pegged to the French Franc since 1945. After the formation of the European Monetary Union in 1999, the peg is now against the larger currency Euro and no longer against one single currency, the French Franc. Has the new peg to the Euro had a positive effect on the CFA countries’ trade flow with the Eurozone compa

This paper quantitatively studies how firm inequality (society-wide firm concentration) in Northern Sweden was impacted by a 2002 deduction to the employment tax. The paper constructs Gini and Theil’s T indices as measurements of firm inequality for 29 Swedish municipalities for the years 1998-2007, where the net sales and number of employees are used as two measurements of firm size.

Ska vi bevara eller riva befintlig bebyggelse som inte längre används? I denna kurs har uppgiften varit att transformera en befintlig byggnad till något nytt, att hitta en ny funktion i ett befintligt skal. Transformation som begrepp och förhållningssätt är relativt nytt, då det historiskt varit vanligare att i många fall riva och sanera äldre bebyggelse som inte längre "behövs". Bevaran

Tillverkning av högteknologiska produkter, såsom litium-jon-batterier och mikroelektronik, sker i så kallade DRY ROOMS. Dessa rum är speciellt utformade för att upprätthålla en mycket låg relativ luftfuktighet. I ett DRY ROOM kan daggpunkten för tilluftluften vara så låg som -40 ℃ eller ännu lägre. Detta är en energikrävande process där hela lokalens luft måste bytas ut för att bibehålla den önskaThe manufacturing of high-tech products, such as lithium-ion batteries and microelectronics, takes place in so-called DRY ROOMS. These rooms are specifically designed to maintain a very low relative humidity. In a DRY ROOM, the dew point of the supply air can be as low as -40°C or even lower. This is an energy-intensive process where the entire room's air must be replaced to maintain the desir

Under Covid-19 pandemin, blev hela värden allvarligt påminda om hur livsviktiga våra lungor är. Under intensivvård övervakas lungorna noga för att snabbt och effektivt kunna åtgärda problem som kan uppstå. De nuvarande metoderna för att diagnostisera kollapsade lungor inkluderar röntgenstrålning. En effektiv metod, men som har några stora nackdelar. Röntgen ger bara en momentan bild av lungtillståThe optical technique, Gas in scattering media absorption spectroscopy (GASMAS) shows promise in application to address current challenges in lung monitoring during intensive care, improving respiratory care by allowing for continuous, non-invasive monitoring. While the technique is already developed in neonatal infant care, the patient profile can be expanded by using higher powered laser systems

Att byggsektorn står inför ett rådande klimatnödläge är ett faktum. Idag investeras hundratals miljarder kronor för att i framtiden kunna producera fossilfritt stål; trots det läggs lite fokus på miljöoptimering av konstruktioner. Syftet med arbetet är att utvärdera hur parametrisk design kan användas som verktyg för att miljöoptimera stålstommar i industritrapptorn samt undersöka vilken profiltypThe fact that the construction sector faces a prevailing climate emergency is undeniable. Today, hundreds of billions of kronor are being invested to develop fossil-free steel; yet little focus is placed on environmental optimization of constructions. The purpose of this work is to evaluate how parametric design can be used as a tool for environmental optimization of steel staircase towers, as wel

The qualitative study is based on semi-structured interviews with six employees. The collected data was analysed and discussed with a template analysis based on

Frågan om klimatförändringarna har kommit att bli en av vår tids mest centrala utmaningar, och såväl om och hur det skall lösas splittrar människor världen över. Bland de mest hängivna finns klimataktivister som, utifrån sin uppfattning om klimatkrisen, tar till olagliga medel för att driva fram förändring. Grupper som Extinction Rebellion och Återställ Våtmarker har som uttalad strategi att använ

For centuries, people have appreciated the taste of wild mushrooms which can be found in nature throughout the European continent and the Fennoscandian peninsula. This is especially so for those of the order of Cantharellales, where you find the Golden Chanterelle among others. Today the commercial aspect of mushroom harvesting has resulted in regulations and guidelines set out by the Nordic Counc

This thesis investigates Swedish voters’ perceptions of political branding and its consequences in a nation characterized by high institutional trust and low corruption. Political branding, a tool for shaping voter opinions, perceptions, and behavior, has gained significant traction in recent years. While traditionally viewed as beneficial for democracy, emerging critiques suggest it may hinder co

This study investigates the feasibility of producing and utilizing biochar as a soil improver in a rural village in Mozambique. It consists of the following two parts, a field study in Mozambique and a theoretical and laboratory study in Sweden. The field study was performed at Project Vita in Linga Linga, Mozambique, which is a non-profitable organization, and the study in Sweden consists of a li

Vågkraft är en energikälla som på många sätt sticker ut från andra förnybara energikällor. Å ena sidan har havsvågor en helt annan regelbundenhet än till exempel vind eller solsken och har därför potentialen att utgöra en mycket mer tillförlitlig energikälla än dessa. Energiinnehållet i världens havsvågor är dessutom oerhört stort och jämförbart med världens totala förbrukning av elektricitet. Å aWave power is a type of renewable energy which holds great potential, but this potential remains largely unused due to difficulties in implementing commercially viable wave energy converters. This study uses Monte Carlo integration to optimize and estimate the electrical power output of a Simulink model based on a real wave energy converter developed by Waves4Power. For 78 sea states defined by th

Bygg- och fastighetssektorn stod ungefär för 34 procent av Sveriges totala energianvändning år 2021. Energianvändningen inom sektorn är främst energin som går åt till uppvärmning. 2021 stod uppvärmningen för ungefär 73 procent. (Boverket, 2024a) Hur brukarna i en byggnad beter sig kan vara en viktig parameter i energianvändningen. Att göra omfattande renoveringar för att förbättra byggnadens energThe construction and real estate sector in Sweden accounted for about 34 percent of the country's total energy usage in 2021. However, within this energy consumption lies a variable influenced not just by building design or technology but by the behavior of its occupants. Behavioral patterns, such as window opening habits, hot water usage, electricity consumption, and temperature adjustments,

The beverage packaging industry is growing rapidly, driven by urbanization and changing lifestyles. Demand for packaged beverages with extended shelf life is driving sales of products with superior barrier properties, due to the high environmental impact of food waste compared to packaging waste. Despite progress, packaging waste represents more than a third of total waste. Thus, milk and plant-ba
