The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. Biomass is a renewable and carbon-neutral energy source that provides heat and power through gasification and combustion. Biomas
Blue cone monochromacy (BCM) is an X-linked retinal disorder characterized by low vision, photoaversion, and poor color discrimination. BCM is due to the lack of long-wavelength-sensitive and middle-wavelength-sensitive cone photoreceptor function and caused by mutations in the OPN1LW/OPN1MW gene cluster on Xq28. Here, we investigated the prevalence and the landscape of submicroscopic structural v
Purpose – The purpose of this article is to investigate attempts to safeguard classical humanism in secondary schools by appealing to a cultural-historical link with Antiquity, voiced in the face of educational reforms in Sweden between 1865 and 1971.Design/methodology/approach – By focusing on the content of the pedagogical journal Pedagogisk Tidskrift, the article highlights a number of examples
An astonishing number of bat fatalities (2,371 belonging to 15 species) were recovered in a provincial surveillance program at wind farms in Cádiz, at the southern tip of Spain, in 2005–2016. We carefully analysed a subset of this sample intending to estimate the true fatality rate in the year 2011, the year for which we had the richest data set (582 fatalities at 38 wind farms). To estimate the t
In this paper, we propose a new estimation procedure for discovering the structure of Gaussian Markov random fields (MRFs) with false discovery rate (FDR) control, making use of the sorted ℓ1-norm (SL1) regularization. A Gaussian MRF is an acyclic graph representing a multivariate Gaussian distribution, where nodes are random variables and edges represent the conditional dependence between the con
Phase retrieval is a numerical procedure concerned with the recovery of a complex-valued signal from measurements of its amplitude. We describe a generalization of this method for multi-wavelength data acquired in a coherent diffractive imaging experiment. It exploits the wavelength-dependent scaling of the support domain to recover separate reconstructions for each wavelength, providing new possi
Controversial evidence points to a possible involvement of methylmercury (MeHg) in the etiopathogenesis of autism spectrum disorders (ASD). In the present study, we used human neuroepithelial stem cells from healthy donors and from an autistic patient bearing a bi-allelic deletion in the gene encoding for NRXN1 to evaluate whether MeHg would induce cellular changes comparable to those seen in cell
In response to the ongoing climate crisis, many countries have issued policies to support the uptake of renewable energy. In the same vein, the European Union (EU) has issued a revised renewable energy directive in 2018. One of the pillars of the directive is the support for community energy initiatives, i.e. sustainable energy initiatives run by or with the participation of citizens. The concept
New generation sequencing (NGS) genetic testing is a powerful diagnostic tool and is increasingly used in the clinical workup of patients, especially in unusual presentations or where a positive family history suggests heritable disease. This review addresses the NGS technologies Targeted sequencing (TS), Whole exome sequencing (WES), Whole genome sequencing (WGS), and the use of gene panels or ge
Purpose: To investigate contemporary results of percutaneous transluminal renal angioplasty (PTRA). Materials and Methods: A multicentre retrospective study analysing all patients treated with PTRA for primary symptomatic renal artery stenosis (RAS) between 2010 and 2013 at four tertiary centres. Procedures during the preceding four years were counted to evaluate for change in PTRA frequency. Resu

Netatmo is a brand of private weather stations that over the past decade, in many countries, have grown to outnumber the number of government based weather stations. In most fields of research, a high number of data points can increase accuracy and precision. For a weather forecast, the more weather condition throughout an area the forecasters know about, the better the forecast. All of Sweden is
In preparation for quantum attacks on current cryptographic primitives, efforts are being made to find ways to construct new primitives. While quantum computers are not yet capable of breaking the keys used in modern parameter selection, efforts are still being made to establish new primitives not vulnerable to any known quantum attacks. These newly proposed solutions range from theoretical constr
This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults). The sample with a pu
Region Skåne has designated seven regional centers in Skåne: Malmö, Lund, Helsingborg, Landskrona, Hässleholm, Kristianstad and Ystad. These centers are to be, among other things, providers of key services. The aim of this thesis is to examine whether Skåne’s students have equal opportunity, through public transport, to benefit from the regional centers’ provision of gymnasiumlevel education. This
Despite stable growth in the national population, many rural municipalities in Sweden are suffering from persistent population decline. Because of the severe consequences this has for their economy and capacity to deliver welfare, many are anxious to find strategies to deal with the situation. This essay examines the local perspective on rural shrinkage by attempting to answer the question: How ca
I Försäkringskassans regleringsbrev för budgetåret 2016 infördes två mål; dels skulle myndigheten verka för att minska sjukpenningtalet till 9 dagar, dels skulle antalet nybeviljade sjukpenningar inte ska överstiga 18 000 i genomsnitt per år. Uppsatsen avser att undersöka dels om Försäkringskassan i sitt beslutsfattande får ta hänsyn till regleringsbrevets volymmål, dels om regeringen överskridit In the regulatory letter for 2016 the Swedish Social Insurance Agency was given two goals; the agency had to work to reduce the sickness benefit rate to 9 days and the number of newly granted sickness benefits should not exceed 18,000 on average per year. The thesis intends to investigate whether the Agency may take these volume targets into account in its decision-making and if the government by
The ability of testing on-chip circuitry is extremely essential to ASIC implemen- tations today. However, providing functional tests and verification for on-chip (embedded) memories always poses a huge number of challenges to the designer. Therefore, a co-existing automated built-in self-test block with the Design Under Test (DUT) seems crucial to provide comprehensive, efficient and robust testi
