This paper is concerned with calculating the branching ratio of the decay A1 −→ Υ + γ of a pseudo-scalar Higgs boson, where Υ is a bound vector meson state of the quarks b and b-bar The results will then be applied to the b. phenomenology of the Next-to-Minimal Supersymmetric Standard Model in the case where A1 has a mass in the interval 9.46 − 12 GeV . The paper will review the concept of spontan
The world wide shortage of helium-3 is forcing the development of new detectors for neutron spectroscopy. A candidate for new detector design that consists of multiple detection volumes in depth, in contrast to the traditional single volume helium-3 detector, is being developed at ESS in Lund. One advantage of the new design is the possibility of utilising the additional depth dimension to extract
The area of direct taxation is, as a consequence of the limited harmonisation within the EU, an area surrounded by several interests that have appeared to be hard to unite. On one hand the EU Member States have the competence in the area of direct taxation to legislate in conformity with their own political considerations. On the other hand the EU law demands conformity with the freedoms regulated
Amartya Sen argues that the overarching goal of development is expanding people’s choices. Yet, freedom as a goal is ambiguous as the notion is clouded by idioms of freedom dating as far back as Ancient Greece. Thus, since Sen claims to have universalist presumptions, this thesis discusses and analyzes Sen’s notion of freedom from a classical philosophical perspective – mainly drawing from Leo Str
The field of radial turbines is wide and radial turbines of today find applications inareas as diverse as small gas turbines; turbochargers for cars, buses, and trucks, railwaylocomotives, and diesel power generators; cryogenic and process expanders; rocket engineturbopumps; and specialty steam turbines, [12]. The three-dimensional flow inside aradial turbine is complex an
In recent years the importance of lobby organizations in the American foreign policy making has increased. One organization that has gained significant influence is the Israel lobby. In this study I present the actors involved in the making of American foreign policy, the relationship America has with Israel and the strategies used by the Israel lobby to gain their influence. I use liberalism to d
Young people account for 40% of all new adult infections worldwide. If education can have preventive effects, great opportunities arise considering this demographic structure of the epidemic since young people are dominating educational enrollment. This thesis investigates the impact of education on HIV prevalence. For empirical testing, five multivariate regression models with ordinary least squa
In this thesis, we address the problem of locating a passive target using a multiple-input multiple-output (MIMO) radar with widely separated antennas (WSA). Using a WSA geometry, the spatial diversity of the transmit and receive antennas are utilized to improve the localization accuracy. First, common numerical algorithms are examined, including the Newton-Raphson (NR) method with the maximum lik
At synchrotron light storage rings there is demand for serving high-brilliance users requesting multibunch operation while simultaneously serving timing users who require single-bunch operation. One method to accomplish this is PPRE developed and currently in user operation at BESSY II. In the method, the transverse emittance of one of the bunches in the bunch train is increased by an incoherent b
The aim of this study was to achieve realistic levels of two different types of aerosols commonly abundant in indoor environments in an experimental chamber intended for human exposure studies and aerosol characterization. The aerosols chosen were particles from candle lights (in particle number dominated by inorganic water soluble particles) and from ozone-terpene reactions (organic particles). T
In this article we argue the need for more socio-legal scrutiny in a digitally mediated and data-driven development. We focus and briefly outline socio-legally relevant aspects of the “sharing” economy, that poses a number of conceptual issues on how we understand and regulate innovative platform based ventures. This also arguably underscores a number of issues relating to the role of consumer and
Introduction Approximately 4–6% of patients treated with oral anticoagulants (OAC) will suffer from major hemorrhage or be in need of urgent surgery necessitating anticoagulant reversal therapy. Several new oral anticoagulants and reversal agents have been introduced that make it difficult for physicians to stay updated on the current evidence of reversal management. This study aims to review the
Soot particle (black carbon) morphology is of dual interest, both from a health perspective and due to the influence of soot on the global climate. In this study, the mass-mobility relationships, and thus effective densities, of soot agglomerates from three types of soot emitting sources were determined in situ by combining a differential mobility analyzer (DMA) and an aerosol particle mass analyz
Popular Abstract in Swedish Vilken musiksmak har blodceller? Forskningen som presenteras i denna avhandling undersöker och drar nytta av hur olika celler uppför sig när de utsätts för ljud. På samma sätt som människor uppskattar olika sorters musik så reagerar olika typer av celler annorlunda beroende på vilka ljud de utsätts för. Cellerna är dessutom ganska konservativa. När de utsätts för ett vOver the last decades the ongoing work in the fields of Lab-on-a-Chip and Micro-Total-Analysis-Systems has led to the discovery of new or improved ways to handle and analyse small volumes of biofluids and complex biosuspensions. The benefits of working on the microscale include: miniaturization of the analysis systems with less need for large sample volumes; temporal and spatial control of suspend
The infrastructure for the third generation of mobile telephony, UMTS, is under construction in Sweden. Within three years four operators were to build competing systems to cover 99,98 % of the population. The case of the 3G infrastructure illustrates how sustainability issues are handled in planning and environmental management, with conflicting goals between institutional levels and contradict
This study investigated the spatial dynamics of bark beetle infestations and their relationships with risk factors in south-eastern Swedish forests during the years 2018–2020, highlighting the importance of spatial heterogeneity of risk factors, particularly under climate change. First, global Random Forest (RF) models were developed to examine the relationships between bark beetle infestations an
Title: Mapping the usage of returnable packaging material and a proposal for improvements - a Case Study at Haldex AB in Landskrona Author: Annika Jönsson Supervisor: Enes Hasic & Anders Pålsson, Haldex AB, Landskrona Eva Berg, Department of Industrial Management and Logistics, Division of Engineering Logistics, Faculty of Engineering, Lund University Examiner: Jan Olhager, Department of Indus
This thesis compares two qualities of flint, one more fine-grained and one more coarse-grained, from the Late Mesolithic Ertebølle site Skateholm I in Scania, Sweden. This in order to investigate what roles the different qualities of flint had in the technological organisation relating to raw material acquisition, choice of technology, and end-product goals. Through a technical analysis of the fli
Drawing on technofeminist and queerfeminist theories this study examines how gender, body and emotions are made through videogames and in processes between the material and the virtual. Centering on how gender-structures limit subjects in conceptions of body and mind, I have conducted interviews with four gender-critical gamers, discussing genderidentities, emotions and experiences of video gaming
