Den yttersta barriären mellan luften och blodomloppet i våra lungor består av en lipid-protein film. Denna lipid-protein blandning kallas för lungsurfaktant. Filmen bestående av lungsurfaktant stabiliserar alveolerna i våra lungor och gör att vi kan andas utan motstånd. Brist av lungsurfaktant kan orsaka svåra sjukdomar, till exempel hos förtidigt födda barn som ännu inte hunnit bilda tillräckligtThis thesis explores lipid self-assembly and aims to give a broad picture of self-assembly structures in simple and complex lipid-protein systems. The systems studied are lung surfactant, stratum corneum and simple model membranes. The lung surfactant mixture lines the alveolus in our lungs and stabilises the air- tissue interface. The lung surfactant lipid phase behaviour was here investigated wi

Biogenic Volatile Organic Compounds (BVOCs) are trace gases other than CO2 and CH4 produced and emitted by the biosphere, where the amounts released depend on climatic factors such as temperature and solar irradiation. However, interpretation of leaf-level measurements is currently hampered by factors such as large within-genotypic variability, measurement height and time in the season. A campaign

The borehole thermal resistance – that is, the thermal resistance between the fluid in the U-tube and the borehole wall – is both a key performance characteristic of a closed-loop borehole ground heat exchanger and an important design parameter. Lower borehole thermal resistance leads to better system performance and/or lower total borehole length and possibly lower installation costs. Borehole th

Syftet med denna uppsats är att ge en överblick över det nya, men snabbt växande, konceptet crowdsourcing. Konceptet kan enkelt beskrivas som en åtgärd att ta en uppgift som vanligtvis utförs av en utsedd arbetspresterande part (vanligtvis en anställd) och outsourca denna till en odefinerad, anonym och generellt stort grupp av människor i form av en ”öppen inbjudan”. Marknaden har under det senastThe purpose of this thesis is to provide an overview of the new, but rapidly growing, concept of crowdsourcing. The basis of the concept can be described as the act of taking a job traditionally performed by a designated agent (usually an employee) and outsourcing it to an undefined, generally large group of people in the form of an open call. In the last couple of decades, the market has exploded

Proteins and peptides are widely used for the prevention, management, and cure of various illnesses. This vast therapeutic potential represents a significant portion of the pharmaceutical industry in the form of vaccines, antibodies, enzymes, and other protein-based therapeutics. During the drug development process, these proteins/peptides are affected by various environmental factors such as temp

Abstract Title: Employees’ experiences of working remotely from home during the covid-19 pandemic - a mixed method study at Försäkringskassan Author: Lina Dahlberg Supervisor: Jan Mewes, Lund University Sweden Course: SOCM03 Master thesis course, Master of Science in Human Resource Development and Labour Relations, 30 credits.

The digitalization of social work in Sweden has skyrocketed in the 21st century. New challenges are rising for social workers as well as social service users. The aim of this study was to explore school counselors' experiences conducting their counseling sessions online. This to find out what hardships they have encountered and how they dealt with them. The aim of this study was to contact gym

The aim of this study was to examine attitudes surrounding the needle exchange program in Malmö and Lund in Sweden. More specifically the aim was to examine how the staff of the needle exchange program experience the attitudes surrounding the needle exchange program and if/how these attitudes affect them in their work. The analysis of nine interviews with staff members revealed similarities in how

Popular science summary: Beavers are back in Denmark The beaver Castor fiber is an animal which used to be common in most places all over Europe. The beaver has also been an important resource for humans, where especially the meat, the thick fur and the castoreum, a secretion that was used by humans in perfume, medicines and food, was wanted. Therefore, hunting by humans has been the main reason

Deforestation, mainly driven by agricultural expansion, is a global problem, interlinked with many pressing sustainability issues of our time, first and foremost, climate change. Previous private corporate initiatives and public policies such as FLEGT and the EUTR have not succeeded in overturning the trend. As a response to that, EU deforestation regulation was developed as the new demand-side po

Adaptive reuse of existing buildings as a part of the circular economy principle has become a more common approach to promote sustainable development, due to increasing urban densification and environmental concerns. Ventilation systems, as a major contributor to energy use in buildings, often face complete replacement during building reconstruction, despite their potential for extended service li

Biomass derived gases produced via gasification, pyrolysis, and fermentation are carbon neutral alternative fuels that can be used in gas turbines, furnaces, and piston engines. To make use of these environmentally friendly but energy density low fuels the combustion characteristics of these fuels have to be fully understood. In this study the structure and laminar burning velocity of biomass deri

The aim of this study was to achieve realistic levels of two different types of aerosols commonly abundant in indoor environments in an experimental chamber intended for human exposure studies and aerosol characterization. The aerosols chosen were particles from candle lights (in particle number dominated by inorganic water soluble particles) and from ozone-terpene reactions (organic particles). T

The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of root s = 7 TeV corresponding to an integrated luminosity of 38 pb(-1). Jets are reconstructed with the anti-k(t) algorithm with distance parameters R = 0.4 or R = 0.6. Jet energy and angle corrections are determined fr

The long-term carbon storage capacity of the boreal forest is under threat from the increasing frequency and intensity of wildfires. In addition to the direct carbon emissions during a fire, the burnt forest often turns into a net carbon emitter after fire, leading to large additional losses of carbon over several years. Understanding how quickly forests recover after a fire is therefore vital to

The European spruce bark beetle (Ips typographus) is an insect species that causes significant damage to Norway spruce (Picea abies) forests across Europe. Infestation by bark beetles can profoundly impact forest ecosystems, affecting their structure and composition and affecting the carbon cycle and biodiversity, including a decrease in net primary productivity (NPP), a key indicator of forest he

Monitoring agricultural land with optical remote sensing offers a valuable tool for estimating crop yield and supporting decision-making for food security. Cropland phenology indicators, such as the start of season (SOS), the end of season (EOS), and the number of growing seasons per year, provide essential information for land managers. While established toolboxes like TIMESAT have been extractin

Developing accurate large-scale drought prediction models is challenging due to the complex temporal and spatial correlation patterns that govern drought dynamics, as well as the compounding effects of anthropogenic activities and global climate change. Although recent advances in deep learning have yielded effective drought prediction models, many struggle to fully capture the heterogeneous spati

Synthetic aperture radar (SAR) remote sensing (RS) technology is an ideal tool to map flooded areas on account of its all-time, all-weather imaging capability. Existing SAR data-based change detection approaches lack well-discriminant change indices for reliable floodwater mapping. To resolve this issue, an unsupervised change detection approach, made up of two main steps, is proposed for detectin

Value of construction projects is traditionally evaluated by the capability to use the facility for the planned purposes. In business premises, however, recent research highlights the creation of value in a project through establishing inter-organizational networks that have the capacity to create long-term value for the businesses in the facility. This article analyzes the lifecycle of a facility
