The UN-affiliated World Health Organization (WHO) estimated that in 2019, more than 90 % of people living on Earth were constantly exposed to concentrations of ambient outdoor pollutants higher than the air quality guideline limits. One of the most notorious air pollutants is particulate matter, consisting of fine natural or anthropogenic particles suspended in the air. Recent studies have shown t

Brunifiering syftar till en process där vattnet blir brunare på grund av ökade halter av naturligt organiskt material och järn, vilket innebär utmaningar för miljön och människor. Sjön Bolmen i södra Sverige har problem med brunare vatten. Eftersom sjön är dricksvattentäkt till 600 000 människor är det av stort intresse att hitta orsaker till brunifieringen. Ryds Å är ett vattendrag i anslutning t

Human activities accelerate climate variations which cause effects all over the world. The IPCC's Sixth Assessment report, which was released in 2021, shows that human activities have already warmed up the planet significantly. The report reveal that the climate has already increased by approximately 1.1 °C since the period 1850-1900 and the average temperature is predicted to exceed 1.5 °C wi

With rising interest rates increasing the cost of capital, businesses are focusing on reducing expenses. Tied-up capital, largely represented by inventory, is a critical cost driver. Therefore, optimizing inventory levels is crucial for controlling capital costs. Inventory levels consist of cycle stock and safety stock. Cycle stock covers average demand during replenishment, while safety stock mit

With the rise of serious environmental threats brought about by climate change, governments, organizations, leaders, and academics are constantly seeking ways to address this growing concern, and the development of a circular economy model is seen as a viable solution towards ensuring environmental sustainability alongside economic growth. The concept of circular economy has been defined in a mult

Nyligen upptäcktes välbevarade fossil från tidig silur på Mösseberg i Västergötland, Sverige. Denna studie syftar till att ge en översikt över materialet samt fastställa dess ålder och karaktärisera depositions- och bevaringsmiljö. Även om fossilt material från Västergötland har väckt vetenskapligt intresse under århundraden, är förhållandevis lite känt om regionens siluriska stratigrafi. Proverna

Dissolved organic matter (DOM) is the major absorber of sunlight in most natural waters and a critical component of the carbon cycle in aquatic systems. The photochemical decomposition of DOM can have a significant impact on the landscape-atmosphere carbon exchange. However, little is known about how changing characteristics of DOM due to water browning (allochthonous inputs of DOM from terrestriaThe photochemical decomposition of the dissolved organic matter DOM can have a significant impact on the landscape-atmosphere carbon exchange. However, little is known about how changing characteristics of DOM due to water browning (allochthonous inputs of DOM from terrestrial sources) affect the photochemical processing of the DOM. A shift from in situ self-produced (autochthonous) DOM to allocht

Den globala uppvärmningen har stora effekter på det subarktiska ekosystemet i norra Sverige. De ökande temperaturerna i dessa ekosystem har lett till ett tinande av permafrosten i marken. Permafrosten innehåller stora mängder kol och när tjälen i marken försvinner blir detta kol tillgängligt för nedbrytning av mikrober i marken. Denna nedbrytning av kol i kombination med en våtare mark leder till The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. The combination of the high microbial activity and overall wetter soils may cause anoxic conditions and in turn methane (CH4) a

An estimated 6% of human greenhouse gas emissions are the result of enteric methane production by cows. Asparagopsis taxiformis, a semi-tropical alga, is one solution. Supplementation of this alga to cows at a small percentage of their daily intake has reduced methane emissions by over 98% in trials. This success has led to multiple commercialization attempts globally, although no Asparagopsis tax

People who desire more-than-one gender are still facing social exclusion as well as exclusion from LGBTQ communities. Moreover, specific bi+ spaces are rare and bisexuals are often not part of them. Where, then, do bisexuals belong? In order to answer this question, this thesis explores the everyday experiences of bi+ people using Relief Maps and in-depth interviews. I build on theories around emo

European identity is a crucial feature for supra-national institution building in times of renewed far-right nationalism and countries leaving the European Union. High- school education may help to prepare young students to become European citizens. Eurobarometer survey data suggests that European identity and education are strongly linked to each other. This statistical connection could be mere c

Environmental brand activism has become a strategy applied by many brands to engage and take a stand in the issue of climate change. The aim is to spur a debate and spark an interest and collective action among the consumers (Sarkar & Kotler, 2018). However, environmental brand activism has not created the same kind of engagement and debate as other forms of brand activism (Manfredi-Sánchez, 2
