The (RB)-B-3 experiment (Reactions with Relativistic Radioactive Beams) at FAIR (Facility for Antiproton and Ion Research) is a versatile setup dedicated to the study of reactions induced by high-energy radioactive beams. It will provide kinematically complete measurements with high efficiency, acceptance and resolution, making possible a broad physics program with rare-isotopes. CALIFA (CALorimet
Lignins are aromatic polymers found in fibrous plants, and a major side-product of paper pulping. They are under exploited due to a combination of economic and technical challenges. Valorisation efforts aim to resolve this, but these rely on informative and reliable analytical feedback. The diverse and complex structures of compounds found in lignins makes analysis difficult. This thesis outlines
Klimatavtryck från Sveriges och världens rikaste har ökat stadigt sedan 90-talet. Samtidigt har de med lägst inkomst minskat sina utsläpp. Nu undersöker forskare om begränsningar för superrika kan bidra till minskade utsläpp. Utopi eller frihetskränkande?
Reflections on ongoing work on the interactions of welfare, planning and landscape, based on a session at the 2021 ECLAS conference.
Using the 3D finite element tool COMSOL a III-V FinFET was mod- eled based on Cezar Zota, Erik Lind and Lars-Erik Wernerssons work. Using this model, the gate-source parasitic capacitance, the gate-drain parasitic capacitance, the source and drain resistances were simulated. Changing the geometry of the FinFET was done in order to optimize the transistor in regard for the transition frequency and
Studies of the Milky Way including how it formed and evolved through time are the key to understanding how other galaxies behave. The Milky Way is the most convenient galaxy to study, because the close proximity of stars means astronomers can collect precise spectral and dynamical data from individual stars. By combining the chemical and dynamical aspects, it is possible to pinpoint stars which ha
In my bachelor project I have worked with some-thing I call “Clothes in the middle phase”. I focused on how people treat their clothes that are not newly washed, but still not ready for the washing machine. I have selected to work with people who tend to pile up their clothes on the floor, bed or another temporary place that can easily create a messy atmosphere in the room. A common behaviour is
I had the opportunity to work with the flood plain community: Nossa Senhora das Gracas in the Amazon in Brazil. During a month long stay I observed the daily life of the people. A life where the inhabitants shape their daily routines after the rising and dropping Solemoes river. Solemoes is a part of the Amazon river. I identified a need of harvesting water during the low water season, when the r
BACKGROUND: Transient tachypnea of the newborn is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Although transient tachypnea of the newborn is usually a self-limited condition, it is associated with wheezing syndromes in late childhood. The rationale for the use of salbutamol
We analyze the eigenvalue problem for the semiclassical Dirac (or Zakharov–Shabat) operator on the real line with general analytic potential. We provide Bohr–Sommerfeld quantization conditions near energy levels where the potential exhibits the characteristics of a single or double bump function. From these conditions we infer that near energy levels where the potential (or rather its square) look
Pulchrol, a natural compound isolated from the roots of the vegetal specie Bourreria pulchra has been shown to possess potential antiparasitic activity toward Trypanosomatids, particularly against Trypanosoma cruzi, which causes the Chagas disease; and moderately against Leishmania species, responsible for Leishmaniasis. In this investigation, several pulchrol analogues were prepared and assayed t
We study questions of existence and uniqueness of quadrature domains using computational tools from real algebraic geometry. These problems are transformed into questions about the number of solutions to an associated real semi-algebraic system, which is analyzed using the method of real comprehensive triangular decomposition.
China is getting old. During the past decades, strict population control has lead to an exceptional increase in the old-age dependency ratio - the number of elderly in relation to the number of working age individuals. In light of shifting demographics, as well as retirees' general tendency towards declining health, this thesis studies health-seeking behavior amongst retirees in China. The stu
Being in their early 20s, Generation Z has left its childhood behind and has entered the job market. However, employers have yet to prepare for their arrival. As strategic communication practitioners lack knowledge about attracting this cohort as future employees to their brand, and theorists in employer branding have overlooked Generation Z largely, this thesis aims to explain factors that enhanc
Since the Rwandan (1994) and Balkan (1990s) atrocities, the humanitarian dimension and in particular the protection of civilians (POC) mandate has become increasingly important in UN peacekeeping operations. It is often used as a visible indicator of a mission’s success. Yet scores of civilian deaths continue to plague missions baring the failures of UN peacekeeping to fulfil its mandate. The aim
The physics of interacting many-body systems is a very complex and challenging subject. Therefore one in general needs to use simplified models and approximate methods for studying these systems theoretically. In this work we study the exchange-correlation (xc) potential for the Hubbard-Holstein (HH) model for the application of Density Functional Theory (DFT) to the same. The Hohenberg-Kohn theo
