In this master thesis project, the formation of fouling on heat exchanger surfaces in dairy processing and mainly the influence of air was examined. Based on prior experimental findings regarding the influence of air bubbles in combination with calculations based on solubility properties of air in milk, a hypothesis was stated. Milk can enter the processing system without any undissolved air, with
Purpose: This study aims to explore the phenomenon of social influence in driving environmentally friendly tourist behaviors. Methodology: To obtain deep and diverse insights about the phenomenon, 20 semi-structured interviews were conducted with respondents representing 13 nationalities. Results: This study revealed that contemporary tourists obtain two conflicting messages from their social en
This qualitative case study aims to explore how the unprecedented impact of the Covid-19 pandemic has affected the capacity and operation of Swedish development organizations within the civil society and to what extent current results-based frameworks (RBF’s) and systems have been suitable to adhere to these changes and challenges. Eight semi-structured interviews with CSO representatives have b
This text serves as a fresh approach to the study of Roman influence on the Scandinavian region. This is achieved through the medium of various bronze statuettes, both from the Roman Empire itself as well as in the form of locally-produced anthropomorphic figures. The study concentrates on four specific regions of Europe; Italy, southern Britain, Denmark, and southern Sweden. All of these areas ma
Water scarcity can have severe implications for society; endangering human health and food security whilst also exacerbating social conflict around the world. These issues are exemplified in the case of the Ferghana Valley in Central Asia, where much of the valley suffers from water scarcity and conflicts despite having adequate water sources. This scarcity is primarily due to how water is used, m
Local adaptation is an important process contributing to population differentiation which can occur in continuous or isolated populations connected by various amounts of gene flow. The willow warbler (Phylloscopus trochilus) is one of the most common songbirds in Fennoscandia. It has a continuous breeding distribution where it is found in all forested habitats from sea level to the tree line and t
Scots pine tree-ring width (TRW) data from Jamtland in the Central Scandinavian Mountains has been used to reconstruct summer temperatures back to 1630 BC. However, it was recently shown that this reconstruction was of limited spatial importance. In this paper, we aim to explain this limitation in the TRW data as a temperature proxy, as well as assess the temperature information from new maximum l
Traditional measures for improved traffic safety need to be complemented by modern technologies in the struggle to reduce the consequences of traffic accidents all over the world. This thesis introduces the Loyal Speed Adaptation (LSA) function based on recent developments in the area of Intelligent Transport Sys-tems to support the vehicle drivers in not using inappropriate or excessive speeds, w
Objective. Peritoneal adhesions develop after almost all surgical interventions in the abdomen. We have developed an efficient treatment against post-surgical adhesions consisting of a combination of positively charged poly-L-lysine and negatively charged poly-L-glutamate. The aim of the present study was to further develop the concept of applying oppositely charged polypeptides in the prevention
Purpose The purpose of this essay was to investigate the welfare level of five visually handicapped children and their families. I want to illustrate the obstacles and possibilities there are for the visually handicapped children to take part of the welfare that's indicated in the Swedish Government Official Report (SoU 2001:55). I also want to give a picture of the support the society gives t
Recent studies have documented large declines in the abundance and diversity of a few well-studied groups of organisms. However, it is unclear how representative the results are for other, less studied groups such as spiders and other ground-dwelling arthropods. A few recent studies have reported large declines in spider abundance, but these have been performed in highly disturbed settings, and ma
Exploitation of agricultural land is today a debated issue. It takes many years for agricultural land to develop and the land is important to preserve for food production. However, land in general is also needed for the development of new housing and new businesses. Today agriculture land is protected by Chapter 3, Section 4 of the Swedish Environmental Code. This section protects agricultural lan
Agricultural intensification is seen as a major threat to global biodiversity. Semi-natural grasslands play an important role in maintaining biodiversity in agricultural landscapes. Biodiversity and community structure in semi-natural grasslands depends not only on local management but also on the surrounding land-use. Further knowledge on landscape-scale effects would help improving the managemen
Mexico City’s water system is not sustainable. There is an unfair inequality gap in the quantity and quality of water access for its residents. Moreover, the groundwater aquifers in the city are being over-exploited and polluted. This has resulted in the sinking of the city, damage to the ecosystems, and the reduction of water access to Mexico City’s residents. As the policies are a direct instrum
Jordarternas utbredning över sydvästra Skåne är ett resultat av Weichselistidens komplexa växelverkande isframstötar, där stora mäktiga kvartära avlagringar finns i anknytning till Alnarpssänkan och Lundadalen. Avlagringarna och deras glaciala ursprung är ett historiskt omdiskuterat ämne. Regionens ytliga jordlager är relativt väldokumenterade men stora frågetecken kvarstår angående avlagringarna The distribution of different Quaternary deposits in southwestern Scania is a result of complex glaciation and deglaciation patterns during the Weichselian, with especially thick deposits in the Alnarp Trough and the Lund Valley. The deposits and their glacial origin have been extensively discussed in the literature. The region’s surficial deposits are relatively well documented, but uncertainties
Geospatial data is becoming increasingly important as artificial intelligence develops rapidly, creating new opportunities in the field of Geographic Information Systems. The thesis investigates the possibility of establishing a method to automatically calibrate a network camera’s geolocation and heading direction by using a camera view image and its corresponding satellite image. The aim is to lo

Early-life adversity negatively affects morbidity and survival in late life, but knowledge is limited about effects on women’s reproduction and reproductive health. To deepen our understanding of the full effects of disease exposure in early life, including long-term consequences, we study women’s reproductive outcomes and their offspring’s health. Using the Scanian Economic Demographic Database a
PURPOSE: RAD51, a central player in the response to DNA damage, has been suspected to contribute to tumour resistance to therapy. A single-nucleotide polymorphism, RAD51 135G>C, in the untranslated region of the RAD51 gene elevates breast cancer risk among BRCA2 carriers. In this study, it was investigated whether this polymorphism is related to prognosis of breast cancer and RAD51 protein express
The manifestation of extreme solar proton events (SPEs) in Beryllium-10 (10Be) ice core data contains valuable information about the strength and incidence of SPEs or local characteristics of the atmosphere. To extract this information, the signals of enhanced production of cosmogenic 10Be due to the SPEs have to be detected, hence distinguished from the variability of the background production by
