After the commercial emergence of 5G, the research community is already putting its focus on proposing innovative solutions to enable the upcoming 6G. One important lesson put forth by 5G research was that scaling up the conventional multiple-input-multiple-output (MIMO) technology by increasing the number of antennas could be extremely beneficial for effectively multiplexing data streams in the s
BACKGROUND: The presence of an apolipoprotein E4 (ApoE4) genotype is the major genetic risk factor for Alzheimer's disease (AD). Astrocytes are the main source of ApoE in the brain, however ApoE can also be produced by neurons and microglia. ApoE plays a role in many cell types and processes related to AD, however, it remains unclear which mechanism(s) and cellular source of ApoE are most critical
Purpose: The aim of this study was to establish a valid national cohort of patients diagnosed with acromegaly by combining data from the general National Patient Register (NPR) and the disease-specific Swedish Pituitary Register (SPR). Methods: Patients ≥ 18 years of age at diagnosis of acromegaly reported from 1991 to 2018 who were registered in the NPR and/or SPR were included. The diagnosis of
We present the organization, instrumentation, datasets, data interpretation, modeling, and accomplishments of the multinational global atmospheric measurement program AGAGE (Advanced Global Atmospheric Gases Experiment). AGAGE is distinguished by its capability to measure globally, at high frequency, and at multiple sites all the important species in the Montreal Protocol and all the important non
Popular Abstract in Swedish Trots ny fordonsteknik så har koldioxidutsläppen ökat med nästan 40% i Europa sedan 1990-talet. Detta beror främst på en tilltagande transport på våra vägar. Drivmedel som används inom transportsektorn är nästan uteslutande diesel och bensin, vilka härstammar från fossila bränslen. För att hantera konsekvenserna av transportfordons miljöpåverkan så blir lagstiftningen pThis thesis deals with large eddy simulations (LES) of turbulent combustion processes in direct injection internal combustion (IC) engines. Modeling of direct injection IC engine combustion involves modeling of turbulent spray/gas two-phase flow, modeling of chemical reactions of large hydrocarbon fuels and coupling of chemistry with turbulent flows. LES is chosen in this thesis for it capability
In this thesis X-ray photoelectron spectroscopy, X-ray absorption spectroscopy, scanning tunneling microscopy,and density functional theory have been used to study the fundamental interactions between model oxidesurfaces and either organic, mixed organic/inorganic, or purely inorganic adsorbate layers. As model oxidesurfaces have served the rutile TiO2(110) surface and an in-situ grown iron oxide
Increasingly social activists, journalists and policy makers have expressed concern over the proliferation of conspiracy theories in the public space. There is a growing fear of their impact on social cohesion and democracy, their power to erode trust in state institutions and science. These concerns often come with an expectation that it is the responsibility of academics to engage with conspirac
A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. This so-called "massive MIMO" promises attractive gains in spectral efficiency with
In recent years, technological developments have been the focal point of the discussion in the shipping industry. The two main topics have been a general discussion on IT security and a discussion about autonomous ships. Concerning IT security, the discussion has been focused on the industry's knowledge in the field and preparedness for any attacks or mishaps that can affect companies that ar
I denna uppsats undersöks den svenska djurskyddslagstiftningen och huruvida den medför ett tillräckligt starkt juridiskt skydd för djuren samt om och i vilken omfattning djurens skyddsvärde får stå tillbaka för andra intressen. De centrala författningarna är djurskyddslagen och djurplågeribestämmelsen i 16 kap 13§ BrB. I uppsatsen behandlas även material från ett flertal djurrättsorganisationer. FThis thesis aims to investigate the Swedish animal protection law and whether not it constitutes a strong enough legal protection for the animals. Also, if and how much the animals’ worth of protection is pushed back to favour other interests. The central pieces of legislation are the Animal Welfare Act and the regulation of animal abuse in the 16th chapter of the Swedish Penal code. The thesis al
Syftet med uppsatsen har varit att utreda på vilket sätt en kvinnas otrohet kan innebära strafflindring för en man som utövat våld mot kvinnan och om det finns anledning att kritisera den nuvarande möjligheten att med framgång åberopa otrohet som en förmildrande omständighet. Den kritiska analysen har delvis gjorts utifrån ett genusperspektiv. För det första kan det konstateras att en kvinnlig parThe purpose of this thesis has been to investigate in what ways infidelity by a woman can work as a mitigating factor for a man who has committed violence against the woman and if there are reasons to criticize this existing possibility to claim infidelity as a mitigating circumstance. A gender perspective has been applied when conducting parts of the critical analysis. It can be established that
Brott och psykisk störning har länge varit föremål för diskussioner på grund av de svårigheter en psykisk störning kan medföra i rättstillämpningen. Sedan tillräknelighetsrekvisitet avskaffades i samband med brottsbalkens införande år 1965 har särbehandlingen av psykiskt störda lagöverträdare förflyttats från ansvarsdelen till påföljdsdelen. Uppsatsens fokus ligger på den svenska rättstillämpnin
Market concept such as sustainability, CSR and sustainable food have influenced the way in which actors on the marketplace behave. Furthermore, previous research have shown that while some market concepts and logics succeed in becoming established among market actors other do not. This in turn has significant consequences on how the market is structured and the behavior of different actors within
The purpose of this study is to explore the opportunities and challenges for self-employed artists who use social media for their business. The research is focused on painters and illustrators who have digitalised and commercialised their own artwork. The method follows a qualitative research framework with a comparative design of multiple cases on the level of individual artists. Seven artists fr
There is a need of developing methods for evaluating material parameters for peat. It is hard and costly to obtain undisturbed samples for laboratory testing of the peat. Therefore, in this thesis the possibility of using in situ measurements of the shear wave velocity for first order estimates of the consolidation parameters has been investigated. In earlier work, relationships have been found be
This is a thesis on the Gê language of Xokleng and its means of subordination. This work is based on previous publication on the Xokleng language (Urban 1985, Gakran 2005, Gakran 2015). In this highly isolation language with almost no inflection, a large set of grammatical and lexical monosyllabic particles are used to express TAM(E). The most obvious grammatical particle is the sentence final mar
In Sweden, buying sex is an illegal act that is also often viewed as immoral, which is understood in this thesis as sex buyers being stigmatized. The aim of this study was therefore to understand how Swedish men who buy sex describe themselves and how they discuss the criminal act of buying sex in an escort forum on the Internet. A qualitative method with a netnographic viewpoint was used wherein
This cross-sectional case study investigates patterns of politicisation in election campaigns of the German Eurosceptic party Alternative für Deutschland (AfD) by means of a comparative multi-level analysis. It adds to the existing literature by examining the Eurosceptic elements of the party’s campaign communication across various decision-making levels. It examines EU issue salience, the dimensi
