Background: Leakage of fire-fighting foam from an airfield caused contamination of the drinking water supplied to a third of the population in Ronneby, resulting in very high serum levels of predominantly perfluorooctane sulfonate (PFOS) and perfluorohexane sulfonate (PFHxS). The results of studies investigating the association between exposure to perfluorinated alkyl substances (PFAS) and pregnan

Background. The live smallpox and Bacillus Calmette-Guérin (BCG) vaccinations have been associated with better adult survival in both Guinea-Bissau and Denmark. In Guinea-Bissau, human immunodeficiency virus (HIV)-1 became an important cause of death after smallpox vaccination was phased out globally in 1980. We hypothesised that smallpox and BCG vaccinations were associated with a lower prevalenc

Background: Skeletal muscle fiber type distribution has implications for human health, muscle function, and performance. This knowledge has been gathered using labor-intensive and costly methodology that limited these studies. Here, we present a method based on muscle tissue RNA sequencing data (totRNAseq) to estimate the distribution of skeletal muscle fiber types from frozen human samples, allow

AbstractBackground and purpose: The need for knee replacement revision arises from a combination of patient, prosthesis and surgeon factors. Registry data can help study these relationships. Pooling data from multiple registries may increase both reliability and generalizability. The study aim was to gain a multi-national overview of knee replacement revision, to inform best-practice and improve o

Objective To evaluate which factors are the most strongly related to self-perceived health among older men and describe the shape of the association between the related factors and self-perceived health using machine learning.Design and setting This is a cross-sectional study within the population-based VAScular and Chronic Obstructive Lung disease study (VASCOL) conducted in southern Sweden in 20

This article presents the proceedings of a symposium presented at the 2004 ISBRA meeting in Mannheim, Germany, October 1, 2004. The organizers and chairpersons were Joseph H. Sisson, MD, and Claudia Spies, MD. The presentations were as follows: "Alcohol: Impact on Mucociliary Clearance"; "Alcohol and Alveolar Epithelial Dysfunction"; "The Reluctant Neutrophil in Lung Bacterial Host Defense During

Emelie Fridell Källsortering i historisk miljö För företag och organisationer kan lokalers utformning och platsbrist gör dem mindre lämpade att ställa källsorteringsmöbler i. Detta kan innebära att en del historiska byggnader på grund av sin utformning har svårare att installera källsorteringsmöbler. Vid undersökning av AF-borgen i Lund gjordes en volymbestämning av avfallsmängderna i två lokaThe resources of our earth are limited and need to be managed sustainably. Managing waste is thus a global issue which makes recycling of waste an important part of sustainable resource management. Sweden has come a long way in source separation of waste compared to many other European countries, with recycling techniques and equipment for source separation, in use. However, most studies look at h

Key words: Innovation, start-ups, exploration, exploitation, formal networks Purpose: The purpose of this thesis is to explore the effects of formal network participation on exploration and exploitation activities in start-ups. Methodology: Following a cross-sectional design, an explorative study was conducted using semi-structured interviews. 18 interviews were performed with representatives fr

To simulate district heating networks, in this project the simulation environment Dymola was used. The goal was to run simulation of district heating network and at the same time have good network representation to easily change between different models and also change between doing simulation and optimization. Different models had to be created in Dymola and tested to ensure they work accordingly

Despite an overwhelming scientific consensus that climate change is a threat to our society, many young Canadians do not view it as a major issue. This suggests flaws in the way that youth are educated on climate change. I therefore investigated climate change education in Canada to recommend improvements. I analyzed Canadian secondary science curricula according to two frameworks to determine ho

Kiselalger, vattenlevande, mikroskopiska organismer med kiselskal, används som bioindikatorer för vattenkvalitet eftersom de är artrika och påverkas av sin omgivning. Processen kallas Kiselalgsmetoden och utförs genom en standard, en standard jag valde att analysera. Proven tas från stenar i vattendrag och sedan görs ett preparat som är fixerat på objektglas som kan undersökas i mikroskop genom aDiatoms, water living, microscopic organisms with silicon shells, are used as bioindicators of water quality because they are diverse and influenced by their surroundings. The process is called The Diatom Method and is accomplished through a standard, a standard I have chosen to analyze. The samples are taken from stones in water streams and then a preparation is made to fix the algae on slides t

The worlds’ human population is continuously growing, and meeting the increased demand for food requires an increase of agricultural production. Agricultural ecosystems are of great importance for humans in terms of delivering provisioning ecosystem services, such as the production of food. The term ecosystem service is a function provided by natural environments, that are beneficial for humans. A

The Swedish law of succession includes a right for the direct heir to retain half of the property in heritage. It is a very strong right, since it is mandatory and goes before a will that trespasses the disposable quota, which is the part of the heritage that the deceased are allowed to dispose through a will. This right is called statuary share of inheritance. The purpose of this essay is to inv

Low-frequency (LF) noise (1/f as well as random telegraph-signal (RTS) noise) measurements were performed on high-performance InGaAs nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs). 1/f noise measurements at room temperature (RT) show that the dominant noise mechanism is carrier number fluctuations. The minimum gate area normalized input gate voltage noise power spectral

Fat-filled milk powders are manufactured by blending skim milk powder with vegetable oil and these powders have gained a great economic importance. Sensible selection of vegetable oil can help in satisfying both nutritional features and functional characteristics of fat for dairy application. The stability of milk powders can be affected by its composition, mainly the composition of fats which can

An article written by the Swedish Government in 2018 outlines that they are working towards a more equal society and describes how they are conducting prevention work regarding men’s violence towards women. Although recently media has portrayed street harassment and catcalling as something that has become an increasing problem for young women in Sweden. Therefore, the purpose of this study was to

The master thesis was carried out for Sandvik SRP in cooperation with the division of Production and Materials Engineering at the Faculty of Engineering at Lund University. This thesis is part of a larger research project with the title ”Blyfria kopparlegeringar” funded by Vinnova within SIO Produktion 2030. Lead-free bearing-materials, which could be used to replace the current bear-ing-material

The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. This, in addition to modeling flexibility from the switches, poses the NEO mo
