Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. This study is purel
Global warming and climate change is getting a serious issue and a great environmental threat that affects many aspects of life and our ways of living on this planet. The negative effects of climate change are endangering our communities, health and economy. Global warming can be considered as a main reason for sea rising levels, extreme heat which is responsible for many forests’ fires, severe dr
I enlighet med bestämmelserna i lagen om genetisk integritet m.m. är surrogatmoderskap inte tillåtet inom svensk hälso- och sjukvård. Vissa ofrivilligt barnlösa som saknar möjlighet till behandling med assisterad befruktning i Sverige, söker sig därför utomlands för att genomgå surrogatarrangemang. Svårigheter kan uppstå när de tilltänkta föräldrarna vill ta hem barnet till Sverige. Eftersom surroAccordning to the provisions of the Genetic Integrity Act, surrogacy is not permitted in the Swedish health care system. Thus some individuals who suffer from involuntary childlessness cannot be offered treatment of assisted reproduction in Sweden. Some of them travel abroad to undergo surrogate arrangements. When the prospective parents wish to bring their child home difficulties arise. Due to th
Many of the coastal areas in Vietnam have elevations below one meter making them vulnerable to salt water intrusion, flooding, and erosion. The Red River Delta (RRD) located in northern Vietnam has suffered severe erosion along certain stretches of coastline during at least the last hundred years. At Hai Hau Beach in the RRD, a land area of 16 km in length and 2.5 km in width has been lost during
A personal transporter is under development at LTH, Industrial Electrical Engineering and Automation, IEA. A wireless link is desired to develop control remotely for the transporter. The development of the control becomes easier without wires and if the transporter can move freely within the range of the link. A link is built, using Bluetooth devices and a microprocessor from Microchip. This link
Mänskliga aktiviteter påverkar den biologiska mångfalden genom en mängd olika aktiviteter som ofta leder till att ekosystem utarmas. Detta leder i förlängningen till stora samhällsekonomiska förluster. Det nuvarande svenska rättsliga systemet för bevarande av biologisk mångfald fokuserar på att bevara och skydda arter som är hotade och specifika områden där dessa lever. Jag ifrågasätter utgångspunHuman activities affect biological diversity in a multitude of ways,often leading to a disruption of ecosystems. In extension this results in large economic losses for the society. The present Swedish system for preservation of biodiversity focuses on conservation of species and the specific habitats of these. I want to challenge the basic premise that biodiversity is best sustained through the pr
Wastewater is an excellent source of nutrients and energy. By treating the wastewater in a clever way, it is possible to both recycle nutrients and recover energy, and thereby create opportunities for a sustainable system. In conventional wastewater treatment where the activated sludge process is used, aeration is needed and a lot of biomass is produced. In regions with warmer climate, or if low-v
Experimental data for through-drying of tissue at intensities comparable to industrial conditions arc presented. The study covers three basis weights, 20, 30 and 40 g/m(2), dried at drying air temperatures of 100, 150 and 200 degrees C. Unlike most experimental data on through-drying in the literature, the experiments in this study were performed under conditions of constant pressure drop across t
PURPOSE: A previous study has shown age- and sex-related differences in abdominal aortic compliance. In that study blood pressure determined by auscultation in the brachial artery was assumed to be equal to blood pressure in the abdominal aorta. To validate our findings we investigated the pressure-diameter (P-D) relationship of the abdominal aorta. METHODS: Diameter and pulsatile diameter change
Beside agricultural soils, tropical rainforest soils are the main source of atmospheric N2O. Current estimates of the global N2O source strength of tropical rainforest soils are still based on rather simplistic upscaling approaches and do have a large range of uncertainty. In this study, the biogeochemical ForestDNDC-tropica model was recalibrated and intensively tested on the site scale prior to
Dual-broadband rotational CARS (DB-RCARS) thermometry has been investigated at high temperature and high pressure. Single-shot measurements were performed at 1800 K, in air and nitrogen at pressures up to 1.55 MPa and in oxygen at pressures up to 0.5 MPa. For all conditions, the resonant signal contribution to the spectra clearly dominated over the non-resonant one, implying the high potential for
Popular Abstract in Swedish Denna avhandling behandlar två ämnen inom trådlös kommunikation: interferens mellan frekvenshoppande (FH) nätverk och fleranvändardiversitet. I arbetet på FH nätverk undersöks ett system där frekvenshopp används för att möjliggöra samtidig tillgång till kanalen för multipla okoordinerade nätverk. Detta åstadkoms genom att frekvenshoppen sker varje gång ett ny paket skaThis thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. This is achieved by performing frequency hops on a packet-by-packet basis, and letting the sequence of hopping frequen
Ectomycorrhizal (EM) fungi are known to colonize minerals in forest soil, and in many laboratory experiments it has been confirmed that EM fungi stimulate dissolution of minerals such as apatite, biotite and feldspars. However, due to the low number of experiments performed in the field, and in forests with different soil fertilities, it is difficult to conclude whether this effect has any ecologi
The objective of the study was to examine the changes in central nervous system (CNS) activity and physical behaviour during induction and awakening from CO2 anaesthesia. Two studies, each using pigs immersed into 90% CO2 gas for a period of 60s were performed. In study 1, we monitored middle latency auditory evoked potentials (changes in latencies, amplitudes and a depth of anaesthesia index), el
This work proposes methodologies using a model-based approach to gain knowledge on and assist the development of an ion-exchange step in a protein purification process; the separation of IgG from a mixture containing IgG, insulin and transferrin. This approach is suitable for capture and intermediate steps in a process. Both methods involve four consecutive steps. Firstly, the retention of the dif
Viral vector-mediated gene transfer utilizing adeno-associated viral vectors has recently entered clinical testing as a novel tool for delivery of therapeutic agents to the brain. Clinical trials in Parkinson's disease using adeno-associated viral vector-based gene therapy have shown the safety of the approach. Further efforts in this area will show if gene-based approaches can rival the therapeut
Background: Embolic strokes of undetermined source comprise up to 20% of ischemic strokes. The stroke recurrence rate is substantial with aspirin, widely used for secondary prevention.

Silicon pixel detectors are at the core of the current and planned upgrade of the ATLAS experiment at the LHC. Given their close proximity to the interaction point, these detectors will be exposed to an unprecedented amount of radiation over their lifetime. The current pixel detector will receive damage from non-ionizing radiation in excess of 1015 1 MeV neq/cm2, while the pixel detector designed
The use of clinical autopsy has been in decline for many years throughout healthcare systems of developed countries despite studies showing substantial discrepancies between autopsy results and pre-mortal clinical diagnoses. We conducted a study to evaluate over time the use and results of clinical autopsies in Sweden. We reviewed the autopsy reports and autopsy referrals of 2410 adult (age > 17)
