Background: Poor mental health is a major issue worldwide and causality is complex. For diseases with multifactorial background synergistic effects of person-and place-factors can potentially be preventive. Nature is suggested as one such positive place-factor. In this cohort study we tested the effect of defined green qualities (Serene, Space, Wild, Culture, Lush) in the environment at baseline o
Objectives. Cirrhosis is a well-known risk factor for hepatocellular cancer, but the true risk in autoimmune hepatitis (AIH) is scarcely studied. Other cancers may arise after prolonged use of immune-modulating drugs. The aim of this study was to investigate the cancer risk in a large cohort of AIH patients. Material and methods. Six hundred and thirty-four Swedish patients in a well-defined cohor
Background: The relationship between smoking and an increased incidence of cardiovascular diseases is well known. Whether smokeless tobacco (snuff) is related to myocardial infarction (MI) or stroke is still controversial. Aim of this study was to explore whether snuff users have an increased incidence of MI or stroke. Methods: A total of 16 754 women and 10 473 men (aged 45-73 years), without his
A 6-cm fresh proximal ileum surgical specimen from a blood group A(1)Le(a-b+) secretor individual was used for stepwise isolation of epithelial cells from villus tip to crypt bottom by gentle washing with ethylenediaminetetraacetic acid-containing buffer. Acid and non-acid sphingolipids were prepared from the epithelial cell fractions and the non-epithelial intestinal residue. Molecular informatio
Samples of settled dust were collected in 14 animal houses and examined for the presence of bacterial endotoxin with the Limulus (LAL) test and the gas chromatography - tandem mass spectrometry (GC-MSMS) technique, based oil the detection of 3-hydroxy fatty acids (3-OH-FAs) as chemical markers of the endotoxin lipopolysaccharide. The median concentrations of the endotoxin in dust determined with L
Aortic valvular disease is a severe ailment that causes great suffering and many deaths worldwide. The exponentially increasing prevalence of the disease has accelerated the demand of a new functioning valve prosthesis. A new approach is to decellularize homograft heart valves, which has demonstrated promising results in clinical trials. The Lung Bioengineering and Regeneration Lab in Lund has dev
This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively. Furthermore,
Matsvinn är ett problem med miljömässiga, ekonomiska och sociala konsekvenser. Nära en tredjedel av maten som produceras i världen idag kastas eller förstörs, något som är ohållbart av en mängd anledningar. Ett forskningsprojekt som drivs för att åtgärda detta är DynahMat-projektet på Lunds Universitet. DynahMat föreslår användandet av temperaturindikatorer och andra sensorer för att beräkna en prFood waste is a problem with environmental, economic and societal aspects. Up to a third of global food production is wasted every year, something that is unsustainable in many ways. Much research is currently being done to alleviate the problem. The DynahMat project at Lund University proposes using temperature indicators and sensor technology to improve food supply chains and provide a more accu
The current global trade scenario has a large infrastructural gap, which limits the possibilities for physical distribution of goods among different countries or continents. The ‘Belt and Road Initiative’ will be used to close this gap. Tetra Pak being global organisation would like to explore the possibilities of using rail transport in BRI. For this reason, they would like to evaluate the benefi
The purpose of this study is to investigate the difference in consumer perception of and purchasing behaviour towards two different categories of companies (“traditional” fast fashion brands and “sustainability-driven” sustainable/slow fashion brands) and their environment-related CSR activities in the global fashion industry. The primary objectives of this paper are to determine if “sustainabilit
Objective Second language learning continues to be a field of growing interest both in academia and everyday life. As such, a more comprehensive understanding of the best learning methods remains an important area of focus. This study aimed to investigate single-session vocabulary acquisition and neural underpinnings of language learning through Diffusion Tensor Imaging (DTI), in relation to immer
The purpose of this thesis is to clarify how, according to BEPS action 1 and action 7, can the amendments of the “specific activity exemptions” in article 5 paragraph 4 of the OECD Model Tax Convention on Income and Capital (the model convention) counter the issue of an artificial avoidance of a PE status. The main issues that are connected to the concept of a permanent establishment are artificia
Idag är planering en essentiell komponent i både den offentliga och den privata sektorn. Ett bra planerad projekt har en högre sannolikhet för att lyckas än ett inte så välplanerad projekt. Men ju större ett projekt är, desto mer tidskrävande är planeringsprocessen. I detta examensarbete utvecklades ett planeringsverktyg för att hitta en tillräcklig bra konfiguration mellan personer och deluppgifToday, planning is an essential part in most lines of business. A good planned project has a higher chance of succeeding than a not so well planned project. However, the bigger a project is, the more time consuming the planning phase becomes. This master thesis has been aimed at designing and developing a planning support tool for finding a good match between persons and tasks based on their ski
Title: A comparison of rail and sea freight from Europe to Asia Authors: Jackie Berg & Louise Pettersson Supervisors: Jan Olhager, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Malin Gejde, Shipping Manager, Tetra Pak AB Background: Transportation mode selection has become a more strategic part of a well-functioning supply chain as globalizatio
Digital technologies have brought new challenges to society, such as data privacy abuses, attacks on democracy, and even military-grade technologies being accessed by civilians. Europe has taken the leadership by regulating different aspects of the digital economy; however, these regulations may create distortions that will harm European businesses. This study tries to draw a picture of the differ
This work investigates how the heat produced by a solar dryer can improve the drying process of newly developed breathable membrane bags for drying and thus preserving fruits in developing countries and the increased efficiency of the process. For that purpose, a solar dryer was built and tested in an indoor solar simulator with similar irradiation as the sun. Due to a limited time span, only one
Intra-regional migration in Latin America is an increasing phenomenon. Many interregional agreements and treaties are being consolidated in the region; however, there are many cases of irregular migration, which leads the migrant worker to be undocumented in the country of destination. The main problem experienced by these undocumented migrant workers is therefore the discrimination experienced by
I September 2009 öppnade den nya konventionen om godsbefordran till sjöss för signering i Rotterdam. Om den nya konventionen lyckas i det den har intention att göra, vilket är att harmonisera reglerna om godsbefordran till sjöss, kommer den nästan hundra år gammal regimen Haag reglerna att försvinna. Dessa konventioner reglerar tillsammans med Haag-Visby och Hamburg reglerna ansvaret för skada på In September 2009, the new convention concerning carriage of goods by sea opened for signing in Rotterdam. If the convention succeeds in what it sets out to do, harmonising the carriage of goods by sea regulations throughout the world, the almost a century old regime of the Hague Rules will be discarded. These conventions, together with the Hague-Visby Rules and the Hamburg Rules, regulate the lia
In early 2019, a system of sensors, projectors, and software was created for the purpose of improving the experience of entering Sony’s offices in Lund, Sweden. The system attracted attention, both internally and externally, and grew organically in features and scope to meet the needs of its initial customers. Due to its modularity and wide applicability, it came to be known as the Interactive Con
