Collimated sprays of paticle, known as jets,are abundantly produced in high-energy proton-proton (pp) collisions, and are predicted by many theories of physics beyond the Standard Model. This thesis reports first on the calibration of jets with focus on the data-driven in situ calibration. Two searches for new physics phenomena in events with jets in the final state are then presented. The analyse

In quantum scattering processes between two particles, aspects characterizing the strong and Coulomb forces can be observed in kinematic distributions of the particle pairs. The sensitivity to the interaction potential reaches a maximum at low relative momentum and vanishing distance between the two particles. Ultrarelativistic heavy-ion collisions at the LHC provide an abundant source of many had

Pepsin-like aspartic proteases (PAPs) are a class of aspartic proteases which shares tremendous structural similarity with human pepsin. One of the key structural features of PAPs is the presence of a β-hairpin motif otherwise known as flap. The biological function of the PAPs is highly dependent on the conformational dynamics of the flap region. In apo PAPs, the conformational dynamics of the fla

We explore the fundamental relations governing the radial and vertical velocity dispersions of stars in the Milky Way, from combined studies of complementary surveys including GALAH, LAMOST, APOGEE, the NASA Kepler and K2 missions, and Gaia DR2. We find that different stellar samples, even though they target different tracer populations and employ a variety of age estimation techniques, follow the

Ultrasonic Additive Manufacturing (UAM) enables the integration of a wide variety of components into solid metal matrices due to the process induced high degree of metal matrix plastic flow at low bulk temperatures. Exploitation of this phenomenon allows the fabrication of previously unobtainable novel engineered metal matrix components.The feasibility of directly embedding electrical materials wi

BACKGROUND: Breastfeeding initiation rates in some developed countries are high (98 % in Sweden and 96 % in Australia) whereas in others, they are not as favourable (46 % to 55 % in Ireland). Although the World Health Organization recommends exclusively breastfeeding for six months, 15 % of Australian women, 11 % of Swedish women and less than 7 % of Irish women achieve this goal. Awareness of wha

Blodet bär med sig syre och näringsämnen som är vitala för vävnadens överlevnad, och därför är karakterisering av hjärnans blodförsörjning av stor betydelse. Blodflödet i kapillärerna kallas för perfusion. Vid MRI-baserad perfusionsmätning i hjärnan utnyttjas ofta signalförändringar orsakade av ett spårämne i blodet. Spårämnet kan antingen skapas internt genom märkning av det arteriella inflödet aDiffusion and perfusion MRI are valuable methods for investigating the microstructure and viability of tissue. One pure diffusion study was included in this thesis, with the purpose of studying microstructure and carrying out size estimations with the q-space diffusion imaging method. This is a method that has predominantly been explored with NMR spectrometers. In our study, a biological phantom c

The present study was undertaken in order to examine the differences between occupations in the Swedish labour market with respect to the risk for men and women of leaving working life prematurely. The project was carried out as a population study employing methodology used in demographics to predict life length at birth. Here, calculations of expected remaining work-life length were based on the

Background: Dizziness is a very common complaint. The frequency of dizziness increases with age. It affects quality of life negatively for older persons in several ways. Objectives: This study intended to investigate which variables (physical activity, loneliness, health complaints, need of help for daily living and falls) differed between those with and without dizziness and also to investigate w

EU-domstolen har sedan flera år utvecklat en praxis avseende rent konstlade upplägg som rättfärdigandegrund för motverkande av skatteflykt. EU har sedan några år arbetat med att förhindra skatteflykt och har nyligen förändrat moder- och dotterbolagsdirektivet genom införandet av en generell skatteflyktsklausul (GAAR). Det kan ifrågasättas huruvida innebörden är densamma i rekvisitet inte genuint aThe European Court of Justice has for several years developed a case law regarding wholly artificial arrangements as a ground for justification to prevent tax avoidance. The last few years, EU has worked to prevent tax avoidance and the Parent- and Subsidiary directive has recently been amended by the introduction of a general anti-abuse rule (GAAR). It is questionable, whether the prerequisite no

This research draws attention to the way undocumented Albanian immigrant women experience their everyday life in Greece. Which are the structural factors experienced by Albanian undocumented immigrant women that defines their everyday life in Greece and what strategies are used by these women in order to resist these macro-structural factors. Qualitative interviews were held with 11 undocumented A

Corporate social responsibility (CSR) is increasingly required of companies. However, CSR at state owned enterprises(SOEs)has not received much attention in the CSR literature. This thesis has the objective to add to knowledge on CSR of Icelandic SOEs. The objective led to three research questions: Q1. How do internal and external factors, affect the implementation and communication of CSR at stat

Bakgrund: Utbrändhet har blivit ett populärt ämne som det forskas allt mer på. Internationellt har många studier om läkares utbrändhet gjorts och de har visat att läkare har en hög nivå av utbrändhet. Dessa studier samt andra studier inom stressforskningen har visat på att det finns många olika orsaker som kan leda till stress och utbrändhet. Mycket lite forskning är dock gjord på svenska läkare fTheory: Burnout has become a popular research field with lots of studies being done within the area. Internationally, many studies on physician burnout have been made and they show that physicians have a high level of burnout. These studies as well as other studies within stress research have shown that there are many different factors that can lead to stress and burnout. However, very little rese

Det här arbetet ämnar undersöka strömlinjeformade landformer i Löberöd med Lantmäteriets nya höjdmodell. Målet är att fastställa isens rörelseriktningar i området under den senaste deglaciationen. Med hjälp av höjdmodellen har drumlinernas ryggar markerats för att bestämma deras orientering i landskapet. Resultatet av detta visar tydligt tre olika isrörelseriktningar i området. RörelseriktningarnaThis work aims to investigate streamlined landforms at Löberöd by utilizing the latest elevation model produced by the Swedish national mapping agency (Lantmäteriet). The goal is to establish the ice flow direction in the area during the last deglaciation. Using the height model, the ridges of the drumlins have been marked to determine their orientation in the landscape. The data clearly suggests

Kan kompensationsprojekt rädda Madagaskars regnskog? Några av de globala utmaningar vi står inför för en hållbar värld är klimatförändringar, fattigdom och utrotning av arter. FN har storskaliga projekt, sponsrade av världsbanken, där de försöker lösa flera problem samtidigt. Ett pilotprojekt sker i östra Madagaskars artrika regnskog, Corridor Ankeniheny Zahamena. Ett stort område av skogen har s
