In 2017, the Danish parliament discussed prayer rooms at educational institutions in a broadly publicised controversy. The debate followed a series of issues arising from such institutions’ changing demography, resulting in increased Muslim presence. Beneath the public and parliamentary debate in 2017, civil servants in ministries and educational institutions became highly engaged in negotiating w

Nature is a central component of the twenty-first-century city. Beyond parks and open spaces, urban nature is implicated in strategies of economic development, climate change mitigation and adaptation, public art, biodiversity enhancement, local food production, health and livability, social justice, community identity, and more.1 This “pluralization” of urban nature has come about in the last four

Numerical simulations are performed to investigate the effects of ambient density (ρam) and nozzle diameter (Dnoz) on the ignition characteristic of diesel spray combustion under engine-like conditions. A total of nine cases which consist of different ρam of 14.8, 30.0, and 58.5 kg/m3 and different Dnoz of 100, 180, and 363 μm are considered. The results show that the predicted ignition delay time

Dark matter direct detection experiments need to know the local phase space density of dark matter fdm(r,v,t) in order to derive dark matter particle properties. To date, calculations for fdm(r,v,t) have been based on simulations that model the dark matter alone. Here we include the influence of the baryonic matter. We find that a star/gas disc at high redshift (z∼1) causes merging satellites to b

The 'European Guidelines on Quality Criteria for Diagnostic Radiographic Images' do not address the choice of film characteristic (H/D) curve, which is an important parameter for the description of a radiographic screen-film system. Since it is not possible to investigate this influence by taking repeated exposures of the same patients on films with systematically varied H/D curves, patient images

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

Solar PV capacity in Sweden has grown considerably in the last years, however and despite techno-economic potential, its share in the power mix remains rather marginal. There are growing claims about economic and non-monetary factors driving the (non-)adoption of solar PV, but quantitative evidence about potential adopters is rather limited. Our study addresses this gap and investigates subsidy ef

The paper considers a time-adaptive finite element method for determination of drug efficacy in a parameter identification problem (PIP) for a system of ordinary differential equations (ODE) that describes dynamics of the primary human immunodeficiency virus (HIV) infection with drug therapy. Tikhonov’s regularization method, optimization approach and finite element method to solve this problem ar

Monetary policy has been suggested to show a fading impact on domestic inflation. Based on this, the study tests whether this has occurred with Swedish monetary policy over the period January 2000 – January 2020. This is done by studying the impact of monetary policy on consumer price inflation and real estate prices in Sweden, comparing the results to the United States. The used method consists o

Since the end of the Cold War, several stateless diasporas residing in Western countries have been involved in separatist conflicts in their homelands. The aim of this thesis is to explore whether these diasporas tend to utilize a universalistic creed of liberalism for particularistic purposes. To fulfill this purpose, I will test the applicability of Maria Koinova’s theory on how diasporas tend t

This thesis paper takes a closer look at the degree to which sustainability and measures thereof are already existent within the media industry, and what development there has been up to now. For this status quo analysis, both the worldwide markets, like the U.S. and several European, as well as a closer look onto the German media market have been taken into account. In addition, a description of

This study was conducted in two lakes, Krankesjön and Vombsjön, located in Lund, Sweden. We went out for four weeks during April in order to scan for PIT-tags eaten by cormorants (Phalacrocorax carbo). These PIT-tags have been implanted in more than 12000 fishes and 12 species during the period between 2003 and 2012. The total numbers of PIT-tags found were 403 and they were distributed over eight

The study was conducted by thematic analysis from secondary data such as literatures, reports and website, and ten interviews which respondents’ backgrounds are experts from ready meal and its packaging related areas. The whole paper followed the structure build from the analysis: Servings and portions, Distributions, Ready meal market and its evolution, Consumer perspective, Ready meal packaging

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

This thesis investigates how an existing multifunctional coworking hub in Stockholm can adapt and improve through functional change to meet new current standards and beyond in our refined digital age. The process is defined by research and insights collected from it, starting with a site analysis of the building and the community in its context followed by a study on adaptive reuse to structurize
