The Former Repairing Tank Facility at the area Hadzici in Bosnia and Herzegovina was targeted by the NATO forces at the end of 1995. As a result, residues of depleted uranium (DU) ammunition have penetrated to the ground polluting the environment to some great extent. Succeeding the war, several people established to the area which has been thereafter transformed into a growing industrial site. T
Det nns olika strålterapitekniker som används för att behandla cancer. Extern strålbehandling är den vanligaste formen av strålterapi. Syftet med extern strålbehandling är att döda eller bromsa cancercellens tillväxt genom att inducera strålskador i DNA, som kommer påverka deras mekanismer och leda till döden. Den eekt uppnås när höga doser levereras till tumören. Problemet som uppstår vid användnPurpose: In 2019 Varian EthosTM linear accelerator (Varian Medical Systems, CA, USA) with integrated artificial intelligence (AI) was installed at Herlev Hospital, Copenhagen, Denmark, enabling online adaptive radiotherapy (oART) e.g for bladder cancer patients with a large margin reduction. The AI utilizes so called influencers for initial delineation of the targets and organs at risks (OAR) usin
Foregin Direct Investment, FDI is often seen to be an important factor to economic growth across the globe. It gives Multinational Enterprises the opportunity to come closer to their customers, but also a chance to achieve economies of scale. In the same way that FDI is considered to benefit a company, economists are also discussing the impact that it brings to the local market. Investments in Chi
This paper presents a wireless receiver frontend intended for cellular applications implemented in a 65 nm CMOS technology. The circuit features a low noise amplifier (LNA), quadrature passive mixers, and a frequency divider generating 25 % duty cycle quadrature local oscillator (LO) signals. A complementary common-gate LNA is used, and to meet the stringent linearity requirements it employs posit
Public participation is vital to ensure sustainable water management, and providing education is one of the way to trigger participation. For decades, developed countries try to educate their citizen to be environmentally literate, and for the water sector, water-related knowledge has been introduced to the public by schools, municipalities and water utilities. The condition is harder for developi
In this master's thesis I analyse how partially changing ideas and procedures regarding democracy can be incorporated into local politics. I argue that you can see a development of a democracy policy field, democracy politics, in Sweden, where politicians introduce initiatives with the aim of involving citizens in decision-making processes. I have chosen to conduct a case study on the city of
The purpose of this thesis is to create a framework for risk and vulnerability analysis on a societal level, meant to be used by Swedish municipalities to produce decision basis in risk- oriented issues. The framework is based on three major principles; a systems approach to risk and vulnerability management, regulation analysis according to Swedish legislation and evaluation principles for risk m
Apart from microhardness and elastic modulus, the stress-strain relation is another important characteristic that more and more scholars have been trying to extract from nanoindentation. With the development of artificial intelligence and computer technology, a machine learning based method is proposed in this paper to extract stress-strain curve of grey cast iron using sharp nanoindentation. Firs
A fast spectral approximation of a narrow-band computer model is proposed for prediction of thermal radiation in a generally nonisothermal and nonhomogeneous combustion environment. The approximation is made by assuming each discretized spatial element along a line of sight to be locally "gray" within each small narrow-band spectrum interval. For each spatial element, the local equivalent spectral
In the present work, a numerical study has been performed to simulate the effect of free-stream turbulence, length scale and variations in rotational speed of the rotor on heat transfer and fluid flow for a transonic high-pressure turbine stage with tip clearance. The stator and rotor rows interact via a mixing plane, which allows the stage to be computed in a steady manner. The focus is on turbin
Fisheries management traditionally relies on stock assessments assuming discrete populations within large administrational areas. However, failing to account for sub-stock structuring may result in overestimation of the stocks' true harvest potential and unsustainable exploitation of small stock elements. Atlantic cod (Gadus morhua) frequently occurs in spatially segregated populations, some of wh
In this paper we consider the problem of solving geometric reconstruction problems with the L-infinity-norm. Previous work has shown that globally optimal solutions can be computed reliably for a series of such problems. The methods for computing the solutions have relied on the property of quasiconvexity. For quasiconvex problems, checking if there exists a solution below a certain objective valu
Abstract in UndeterminedOne sediment core from the Jarnavik bay in Blekinge archipelago has been investigated for its content of pollen and diatoms and its chemical properties. Two levels were also dated by radiocarbon. Based on the results the sediment sequence analysed has been divided into three environmental units largely corresponding to the lithology of the sequence. A lowermost unit consist
By using both mitochondrial and nuclear multiloci markers, we explored population genetic structure, gene flow and sex-specific dispersal of frillneck lizards (Chlamydosaurus kingii) sampled at three locations, separated by 10 to 50 km, in a homogenous savannah woodland in tropical Australia. Apart from a recombinant lizard, the mitochondrial analyses revealed two nonoverlapping haplotypes/populat
Although most institutions offer some kind of follow-up to patients operated on for colorectal cancer, its value with respect to prolonged survival has been challenged. However, improved results of liver surgery and chemotherapy make it reasonable to assume that a follow-up programme leading to detection of more asymptomatic recurrences would result in improved survival. Liver metastases and extra
Background: Evolutionary theory predicts that antagonistically selected alleles, such as those with divergent pleiotropic effects in early and late life, may often reach intermediate population frequencies due to balancing selection, an elusive process when sought out empirically. Alternatively, genetic diversity may increase as a result of positive frequency-dependent selection and genetic purgin
The osmotic pressure of polyelectrolyte solutions as a function of concentration has been calculated by Monte Carlo simulations of a spherical cell model and by molecular dynamics simulations with periodic boundary conditions. The results for the coarse-grained polyelectrolyte model are in good agreement with experimental results for sodium polyacrylate and the cell model is validated by the bulk
Many linear dynamics over networks can be related by duality to the evolution of a Markov chain with state space coinciding with the node set of the network. Examples include opinion dynamics over social networks as well as distributed averaging algorithms for estimation or control. When the transition probability matrix P associated to the Markov chain is irreducible, a key quantity is its invari
There is a strong political desire to reduce the use of fossil fuels in road transport. In this paper, the use of e-bikes (of the pedelec type) in Sweden is analysed by focusing on changes in travel behaviour and their corresponding effects on CO2 emissions. The aim is to analyse the effect on CO2 emissions due to the use of e-bikes. The analysis is carried out on the possible differences in chang
Objective: We characterized the vasodilatory effects of ANP, BNP, and CNP in human subcutaneous arterioles in vitro and the cutaneous microcirculation in vivo. Methods: The in vitro experiments were performed using wire myography and the responses were characterized by the use of inhibitors for nitric oxide (L-NAME), prostaglandin synthesis (indomethacin), or the endothelium-derived hyperpolarizat
