The importance of recycling nutrients becomes more important as the finite resources starts running out, and recycling of urine nutrients is an important factor in developing a sustainable society that takes advantage of nutrients already existing in the system. Urine only represents one percent of the domestic wastewater volumetric flow, but contains 80 % of the nitrogen, 50 % of the phosphorus a
This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. The handheld nanoparticle detector Partec
Popular Abstract in Swedish Ett felaktigt protein som klumpar ihop sig i hjärnans blodkärl är orsaken till hjärnblödning och för tidig död hos unga islänningar. Sjukdomen är ärftlig och uppkommer på grund av en enda felaktig byggsten, orsakad av en mutation, i proteinet cystatin C. Det muterade proteinet bildar mikroskopiska proteinkedjor, fibriller, som klumpar ihop sig i bland annat hjärnans bloThe pathophysiological process in Alzheimer’s disease and other amyloid disorders usually involves the transformation of a soluble monomeric protein via potentially toxic oligomers into amyloid fibrils. The structure and properties of the intermediary oligomers have been difficult to study due to their instability and dynamic equilibrium with smaller and larger species. This has hampered the devel
This paper presents two circuits, a complete 1.5 V 28 GHz SiGe beam steering PLL and a standalone 28 GHz QVCO with I/Q phase imbalance detection and compensation. The circuits were designed in a SiGe process with f T = 200 GHz. The PLL is intended to be used for beam steering in an 81–86 GHz E-band transmitter. Phase control is implemented by DC current injection at the output of a Gilbert archite
The purpose of this study is to describe and analyse changes in the pledge element of the ordination in the Church of Sweden. The transition in 1893 from a clerical oath to an affirmation will be particularly in focus and its causes and effects identified. My intention is thus to contribute to the history of the Swedish clerical oath, describing its complexity and multifarious range of meaning. In
Extensive field measurements have been performed at three CarboEurope-Integrated Project forest sites with different topography (Renon/Ritten, Italian Alps, Italy; Wetzstein, Thuringia, Germany; Norunda, Uppland, Sweden) to evaluate the relevant terms of the carbon balance by measuring CO2 concentrations [CO2] and the wind field in a 3D multi-tower cube setup. The same experimental setup (geometry
Popular Abstract in Swedish Grundvatten, det vatten som förekommer i hålrum i underjorden, är en av våra allra viktigaste naturresurser. Grundvattnet utgör den absolut största andelen för oss tillgängligt färskvatten och används för att producera mat och som processvatten inom olika industrier. Ungefär hälften av jordens dricksvattenförsörjning baseras på grundvattenuttag och ekosystem världen övePesticides are known to occur in groundwater worldwide. However, long-term pollution concerns and cause-effect relationships for specific regions remain limited. This thesis explores the occurrence of pesticides in south-Swedish groundwater, with the aims of providing a better knowledge basis for assessment and management of present-day and future pollution risks.

While migrating to other countries, persons with disabilities often face additional obstacles as non-nationals and having a disability. Being a vulnerable group it might be hard for them to access remedies and justice. As a light in the darkness, the Convention on the Rights of Persons with Disabilities was adopted in 2006 in order to promote and protect the human rights of persons with disabiliti
Bullberget är beläget i västra Dalarna i Lima socken. Huvudbergarten utgörs av Öjediabas, som här är genomslagen av en horisontell diabasgång tillhörande samma generation som den i Dalarna rikligt förekommande Åsbydiabasen. Denna diabasgång uppvisar en steglös övergång från en Si02-halt på 54% till 73%. Även bergartens makroskopiska utseende förändras helt utan synliga kontakter. Bergarterna har tThe Bullberget hill is situated in the Lima parish of the Dalarna province in western Sweden. The major rock forming the hill is Öje basalt. This is cut by a dolerite sill belonging to the same generation as the Åsby dolerite, which is common in the province. The sill displays a continuos transition from a SiO2-content of 54% to 73%. No lithological boundaries have been found between the various r
Populärvetenskaplig sammanfattning: I det svenska urberget finns stora mängder av granit och andra magmatiska bergarter. Dessa magmatiska bergarter förekommer i både deformerade och odeformerade varianter. Majoriteten av de magmatiska bergarterna anses ha bildats genom att en oceanplatta har glidit ned under en kontinentplatta med hjälp av spridningsprocesser vid oceanryggarna. Oceanplattan smälte
The field of particle physics is ever evolving. With the recent advent of the Large Hadron Collider (LHC) it is possible that the long sought for Higgs boson is detected. While this is not certain even if it is found it is likely that it will need more precise methods of investigation. For this and other reasons, a new collider called the International Linear Collider (ILC) is being planned. This

More specifically it aims to provide an understanding of how this new way of consumption can be understood as a part of an on-
Sexuella övergrepp mot barn tillhör de mål som är allra svårast att hantera i svenska domstolar. Ofta består bevisningen i målet endast av barnets utsaga, vilket medför svåra bevisvärderingsproblem. Högsta domstolen har i NJA 2010 s. 671 fastslagit ett antal kriterier som kan vara behjälpliga vid bevisvärdering av muntliga utsagor. Vad som bland annat kan beaktas är om utsagan är lång, sammanhänga

Sweden has been struggling with bad access to healthcare. The National Healthcare Guarantee is not fulfilled, and Sweden has low productivity numbers. One suggested solution to deal with this issue is increased healthcare production control. Healthcare production control (HCPC) is the activity to actively trying to match healthcare needs with capacity. Public authorities are advocating increased h
Purpose: The purpose of this study was to describe the perceptions of auditors at different career stages on current management control and the work environment. In order to gain a deeper analysis of the auditors' perspective, the study has used previous empirical research and theories of motivation and job satisfaction. Thus, two research questions have been formulated to support the study.
Utsläpp av kväve i naturen är ett stort problem eftersom det till exempel kan bidra till övergödning och så kallade döda bottnar i sjöar i akvatiska och marina miljöer. Förmågan att kunna avlägsna kväve från avloppsvatten har därför blivit ett viktigt medel för att bevara och skydda miljön. Kväveavskiljning från kommunala avloppsvatten sker vanligtvis med hjälp av nitrifikation och denitrifikationEmissions of reactive nitrogen to the environment is of major concern, e.g. since it is known to contribute to eutrophication and dead sea floors in water bodies. The capability to remove nitrogen from wastewater has therefore become a critical means of preserving and protecting the environment. Conventional nitrogen removal from municipal wastewaters usually includes nitrification together with d
