Perfluoroalkyl substances (PFASs) can interfere with male reproductive function, but evidence in humans is limited. Six hundred four fertile men (199 from Greenland, 197 from Poland and 208 from Ukraine) were enrolled in the study. We measured four PFASs in serum (PFOS, PFOA, PFNA and PFHxS) and concurrent DNA damage in spermatozoa by sperm chromatin structure assay (SCSA) and in situ terminal deo
The 1990s was the era of human rights awareness, democratic transitions, and growing involvement of international organizations and the nongovernmental sector in human rights education (HRE). The UN Decade for HRE from 1995-2004 was not only born out of the initiatives and pressures of nongovernmental organizations (NGOs) but it also actively triggered many new private initiatives and commitments
During the past decades there is a growing interest to include a cultural dimension in the debate on sustainable development. In this thesis I explore how culture, and more specifically the Flemish cultural sector, contributes to the transition to a sustainable society. By means of case studies, I examine how cultural organizations perceive their role in the transition process and how they transla
Bakgrund: UNFPA är en underorganisation till Förenta Nationerna (FN). UNFPA fokuserar på populations- och utvecklingsstrategier och jämlikhet mellan könen. I mars 2005 bestämdes det i UNDP/UNFPAs styrelse att UNFPAs inköpsavdelning (PSB) skulle behöva förbättras om de skulle nå upp till sina mål. Flera studier har genomförts och resultatet av dessa visade bland annat på en rekommendation att införBackground: UNFPA is a subsidiary organ to the United Nations (UN) with a primary focus on population and development strategies, sexual and reproductive health and gender equality. In March 2005 the UNDP/UNFPA Executive Board had realized that for the UNFPA Procurement Services Branch (PSB) to operate in line with its mission, focus would need to be directed specifically towards improvements in t
Abstract Nutrient availability is one of the most important components of soil chemistry, and has Been shown to strongly impact ectomycorrhizal community composition and diversity. Phosphorous, magnesium, and potassium are important macronutrients for plant growth. Tree growth in the boreal and temperate forests is immensely dependent on their fungal mutualistic partners for their nutrition, parti
Abstract Toxic cyanobacterial blooms can form in both freshwater and marine environments, which could threaten the health of human beings and animals. The genera that are known for causing the scums in freshwater are Anabaena, Microcystis, Cylindrospermopsis and Planktothrix. In order to control lake water quality and minimize the potential health risk associated with the cyanobacterial blooms, th
In this thesis I studied how the level of cooperation has changed in the United Nations Security Council (UNSC) since the Cold War, as the international arena went from being a bipolar power structure to a unipolar one. My perspective on cooperation was based on the theory of realism. In order to answer these questions I analyzed veto usage and the resolutions as indicators of cooperation. Veto us
This report is a fire risk assessment of Norrköpings Art Museum and is written as a part of the Fire Protection Engineering program at Lund University. The three scenarios that are evaluated in the report come from a coarse qualitative analysis conducted after a visit at the object. Programs like CFAST, FDS and SIMULEX has been used to implement this analysis. The results obtained from these progr
In this paper the laminar burning velocities of nitromethane, ethanol and nitromethane-ethanol mixtures has been determined by using heat flux method. The laminar burning velocity of ethanol was measured at atmospheric pressure, initial temperatures range 298-358 K and equivalence ratio 0.7-1.6. The flame speed of ethanol shows a satisfactory agreement with previous available data. The burning vel
Pollenanalys och landskapsrekonstruktionsmodellering (modellen REVEALS) användes för att undersöka landskapsutvecklingen i Botorpsströmmens dräneringsområde i södra Sverige över de senaste 2000 åren. Studien ingår i två större projekt, The archaeology and ecology of collapse: social and agricultural change following the Black Death och Managing Multiple Stressors in the Baltic Sea. Resultaten frånThis thesis reports the results from a pollen analytical and quantitative landscape reconstruction (REVEALS model) study in the drainage area of the Botorpsströmmen River in southern Sweden as a part of the project The archaeology and ecology of collapse: social and agricultural change following the Black Death and the project Managing Multiple Stressors in the Baltic Sea. The focus of this study
Abstract Failures in achieving the 2010 goals of slowing down or halting the loss of biodiversity, and the setting of new biodiversity targets set for 2020, stress an urgent need to expand current reserve networks and to improve their effectiveness in protecting species and habitats. Habitat suitability models, and derived maps from them, are among the broadest used tools for identifying the ecol
Snowball is a new development board for embedded designs presented by ST-Ericsson. It features a fast ARM based 1GHz processor. There are currently two officially supported operating systems available for the Snowball: Android and Ubuntu. There is a brand new mobile operating system in development called Tizen. Tizen is developed among others by Samsung and Intel and features a HTML5 based softwar
The purpose of this thesis is to produce an example of a solution to the problem with varying space requirements in divorced families living one-and two-family houses in Sweden. We have focused our work on solving this with a stand-alone complementary building which contains all the critical functions a dwelling should have. To facilitate and make the investment more realistic the building should
The purpose of this Master’s Thesis is to investigate how the risk of onset of mould and decay will change due to a changing climate. The research encompasses the time period 1960-2099 in open fields near the cities Göteborg, Lund, Stockholm and Östersund for the emission scenarios A1B, A2 and B1. The risk of onset of mould and decay is studied on wood in outdoor climate as well as the risk of
The purpose of the study was to investigate how social workers in the substance abuse and addiction services perceive collaboration with the psychiatric unit, and if the size of the municipality has a role in the extent to which collaboration takes place. A quantitative survey has been conducted with 40 respondents operating in a larger city and 15 respondents operating in a smaller city. The stud
De senaste åren har flera straffskärpningar gjorts inom lagstiftningen, inte minst för unga lagöverträdare. Den här studien syftar till att analysera de möj-liga konsekvenser på samhället och påföljdssystemet som ett förslag på såd-ana straffskärpningar gällande unga myndiga i åldern 18-20 år, kan ge. Betän-kandet 2018:85 Slopad straffrabatt för unga myndiga ligger till grund för denna studie. DetIn the last few years there has been several increases in the severity of pun-ishment within the Swedish legal system. This is especially true for the legis-lation concerning young offenders. This study aims to analyze the possible consequences on the society and the penalty system that a proposal for such increased penalties can have on young adults aged 18-20 years. SOU 2018:85 Slopad straffraba
The aim of this project was to develop analytical methods for characterizing rheological behavior of creams. The rheological methods of shear ramp, thixotropy, amplitude sweep, and frequency sweep, as well as texture analysis were initially developed at LTH and later transferred to Galenica. For this project two series of emulsions were formulated and used as test subjects for these methods. One u
Developing and getting a new medicine approved is a long and expensive process and it would therefore be beneficial if it could be streamlined. In order to control the effect and safety of a new treatment, clinical trials are performed. Traditionally, these have been performed at physical clinics, but with digitalization the option to collect clinical data remotely has been presented. This thesi
