Combined with concerns about climate change, air pollution and human health, the COVID-19 pandemic has renewed the use of and policy interest in active transport (AT) modes, namely cycling and walking. However, we note a high degree of uncertainty and lack of assessments addressing the economic benefits of AT policies; particularly when they are used as a mix of policies at the local level. This s
Mechanobiology plays an important role in tendon healing. However, the relationship between mechanical loading and spatial and temporal evolution of tendon properties during healing is not well understood. This study builds on a recently presented mechanoregulatory computational framework that couples mechanobiological tendon healing to tissue production and collagen orientation. In this study, we
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
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
This study analyzed highly detailed long-term information about occurrence of cormorants (Phalacrocorax carbo sinensis) and the fish community composition in lake Krankesjön, southern Sweden. Moreover, cormorant predation with regards to species and size preference were estimated using data from recovered PIT (Passive Integrated Transponders) tags. The results shows that the cormorant population h
This thesis investigates how manufacturing of asphalt containing recycled materials can be conducted when the purpose is to use the recycled material in another road construction. The study show that manufacturing of asphalt containing recycled materials then can be conducted in three ways, through hot, less hot and cold manufacturing processes. The possible use of the final products is dependent
Recent advances in the sequencing technology have led to an increasing pressure on the computer programs used for analysing the sequence data. The programs should be able to provide accurate analysis in a reasonable time span. 16S and 18S rRNA analysis is performed by using PCR to amplify the genes from microorganisms present in a sample followed by sequencing of the amplicons. The result is files
A rectangular, straight microchannel heat sink with multiple length bifurcation has been designed, and the corresponding laminar flow and thermal performance have been investigated, numerically. Five different cases with multiple length bifurcation and various arrangements are investigated, as well as one case without bifurcations. All laminar fluid flow and surface heat transfer results are obtai
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
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
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
There is an increasing shift of hope from international negotiations to local actors for promoting sustainability by ‘thinking globally while acting locally’. Municipalities are such carriers of hope, taking on increasing responsibility as implementers of sustainability. The problem is that sustainability is a social construction site, and implementing it means ‘making it up as you go’. With this
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
This paper will investigate the conflicts that can arise during destination development following a World Heritage inscription. Previous literature mentions that conflicts arise, but focuses on a more managerial perspective, and fails to account for the characteristics of those conflicts. The aim of the paper is to account for the characteristics of the conflicts that arise, by trying to grasp how
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
This thesis examines the frontier defensive system found in the vicinity of the Roman auxiliary fort near modern-day Bologa, Cluj County, Romania. The goal is to study the visual relationship between the more certain watchtowers and the other military installations (the auxiliary fort and other fortlets) to understand how arrangements and visibility might have contributed to the functioning of the
