This study aimed to determine the optimal method for extracting rosmarinic acid (RA) from lemon balm using pressurized liquid extraction (PLE). Additionally, the effect of filtration during sample preparation on the concentration of rosmarinic acid (RA) was investigated. Moreover, the RA content was compared in various lemon balm samples including: commercial dried lemon balm, commercial lemon bal
Hospitals have been a crucial element of healthcare for centuries, providing a space for diagnosis, treatment, and recovery. The design of hospitals has evolved dramatically throughout history, with significant changes in both the form and function of these institutions. Ancient hospitals were closely connected to nature, with an emphasis on the role of surroundings in the healing process. However
Rainforests are of great importance for biodiversity and several ecosystem services. In Rwanda, a considerable decline in rainforest covers have been observed during the last decades. The Gishwati-Mukura Forest is one of the rainforests in Rwanda that has experienced a substantial reduction in forest cover, 99.4 %. The aim of this research has been to investigate what the changes in forest cover o
Godstransporter är livsviktiga för att en stad och stadslivet ska fungera, men sättet som godstransporter genomförs idag är inte hållbart. Det finns få riktlinjer på hur transporterna ska ske och riskfyllda situationer uppstod. Syftet med examensarbetet var att undersöka problem i bilfria områden i centrumnära stadsmiljö, samt att komma med rekommendationer på hur det kan utvecklas utifrån dagens Urban freight transportation is crucial for the functioning of a city and city life. However, the way urban freight transportation is occurring is unsustainable since there are few regulations and dangerous situations easily arise. The purpose of the thesis was to examine transportation in car-free areas and identify the associated problems, guidelines and explore potential solutions to the identi
Intermarriage patterns are often referred to as a step in the social assimilation. However, previous research on is ambiguous in its result concerning differences in intermarriage pattern between genders. According to the theory intermarriage patterns are both influences by preferences and opportunities. This thesis conducts a conditional fixed effects logistic regression to analyses the intermarr
This thesis investigates: 1) how the Hanfu is presented in videos on social media by young Chinese women and how the netizens respond to it, and 2) in what way the Hanfu Movement might be contributing to the legitimization of the Chinese government’s nationalism in Post-2013. Post-2013 China uses ancient Chinese culture to strengthen the country through national unity and the removal of Westerniza
The EU procured for roughly 202000 MEUR (14% of the EU GDP) during 2021 in the public sector. The majority of these contracts are traditional, linear business model purchases. The EU has been developing several strategies, guidelines, and policies for sustainable purchasing, with Circular Public Procurement for a Circular Economy (CE) being one of them, but the implementation rate is low. Electron
In this thesis I aimed to answer the question of how American combat veterans from World War II created their personal narratives of their experiences. The main theoretical framework was Samuel Hynes' work about war narratives and personal narratives. I used two theoretical perspectives that to answer this research question where the first perspective was for emotional factors, which was focus
Forests and forest products are important, not just for timber production, the forest ecosystem plays several important roles, such as water purification, carbon sequestration for climate mitigation and recreational values. How the forests are managed varies throughout the globe, in Sweden the most used system is the clearcutting system (CF), however continuous cover forestry (CCF) is gaining popu
This paper aims to analyze the impact of grandparents' childcare on mothers' employment status and working hours in China. Based on the cross-sectional data of China Family Panel Studies (CFPS) in 2020, this paper uses the Probit and the OLS models to study married women aged 20-50 with at least one child aged 0-6. The empirical results show that grandparents' childcare increases the p
Language-based assessment (LBA) from open questions (e.g., how are you feeling?) analysed with natural language processing has predicted corresponding rating scales scores towards the theoretical upper limits. However, rating scales do not hold objective truth regarding psychological constructs. Therefore, the present pre-registered study set out to further validate LBA in a natural setting. Using
There is a need to transform the urban mobility regime to mitigate climate change and improve living quality in cities. Cargo bikes (CBs) offer a promising solution to replace motorized vehicles, especially for last-mile deliveries and private logistics. They show considerably lower carbon intensity, occupy less space and help reduce air and noise pollution in cities. CB sharing relieves individua
Low tax revenues in many African countries are hindering sustained economic development and aid could have an inhibiting effect on the development of fiscal capacity. This paper will use newly published high-quality data on tax revenues to dive deeper into the effects of aid on hard-to-collect taxes in Africa between 1960-2015. Previous aid literature has mostly focused on short-term effects on re
It is important to look more deeply into how forest owners choose to manage their forests. If Continuous Cover Forestry (CCF) can be a suitable way for some forest owners to work with nature conservation management, and if it could work as a tool in their forest production today. This is because silvicultural methods can have a significant impact on the climate and the country's economy. In th
Since the early 2000s, the issue of ‘honour-based violence’ has sparked significant discussions in Sweden, leading to governmental and civil efforts to combat this form of violence. An essential intervention highlighted in these efforts is improving knowledge among professionals in sectors such as social and healthcare, schools, and the judicial system. Recently, a new platform has emerged, offeri
Disaster loss accounting is an essential tool for assessing the effects of disasters and creating policies for disaster risk reduction that are supported by data. This study compares disaster data for two of the most used disaster loss accounting databases, EM-DAT and DesInventar in the context of six Latin American countries, namely, Uruguay, Chile, Costa Rica, Nicaragua, Honduras, and Venezuela.
This study examines the potential of a nutrient-based emissions trading system and focuses on its possible implementation in the Baltic Sea region to address the problem with eutrophication in the inland sea. Emissions trading has proven to be an effective method for reducing greenhouse gas emissions within the EU through the EU ETS. The study evaluates whether similar outcomes can be achieved
Uppsatsen tar fram olika modeller och teorier om nätverk och vad som kan påverka nätverk. De begrepp som tas upp som påverkar nätverk är bland annat digitaliseringen i form av digitala verktyg, sociala plattformar och kommunikation. Sedan intervjuas 5 entreprenörer som driver konsultföretag i ekonomibranschen där frågor ställs kring deras nätverk. Slutligen visade det sig att digitaliseringen har
