A search is presented for the production of new heavy quarks that decay to a Z boson and a third-generation Standard Model quark. In the case of a new charge +2/3 quark (T), the decay targeted is T -> Zt, while the decay targeted for a new charge -1/3 quark (B) is B -> Zb. The search is performed with a dataset corresponding to 20.3 fb(-1) of p p collisions at root s = 8TeV recorded in 2012 with t
This paper describes a search for dark photons (γd) in proton-proton collisions at s = 13 TeV at the Large Hadron Collider (LHC). The dark photons are searched for in the decay of Higgs bosons (H → γγd) produced through the ZH production mode. The transverse mass of the system, made of the photon and the missing transverse momentum from the non-interacting γd, presents a distinctive signature as i
Background and purpose — Obesity has been associated with inferior outcomes after laminectomy due to central lumbar spinal stenosis (CLSS); we evaluated whether this occurs in surgery on national bases. Patients and methods — We retrieved pre-and 1-year postoperative data from the National Swedish Quality Registry for Spine Surgery regarding patients aged ≥ 50 with laminectomy due to CLSS in 2005–
INTRODUCTION: Mental health workers' attitudes toward individuals who self-harm impact accessibility and quality of care. Previous studies have established the role of training on professionals' attitudes, with mixed findings for gender and work experience. While self-report attitudinal scales are frequently used, latent response trends across such scales are seldom considered. The present study e

The metabolic syndrome includes a cluster of dysfunctions that identifies subjects at high risk of developing type 2 diabetes and cardiovascular disease. The prevalence of the metabolic syndrome has increased markedly over the last two decades. Central to this syndrome is insulin resistance and hyperglycaemia, but also other manifestations, e.g. central obesity, dyslipidaemia, elevated blood press
Psychological disability caused by stress is likely to affect cognitive and emotional functions, such as memory, attention, concentration, and decision making. These functions are essential in a train driver’s work, who is responsible for his or her own and others’ safety, and for this purpose requires optimal work capacity. Eighteen train drivers, 40 – 56 years old, most of them with long work ex
Galectin-4 belongs to a subfamily of galectins composed of two carbohydrate recognition domains within the same peptide chain. The two domains have all the conserved galectin signature amino acids, but their overall sequences are only approximately 40% identical. Both domains bind lactose with a similar affinity as other galectins, but their respective preferences for other disaccharides, and larg
Hormones and neurobiological factors may be regulated differently in suicidal versus non-suicidal depressive patients. There is currently limited knowledge about the relation of substances in the Renin-Angiotensin-Aldosterone system to depression and suicidality. We therefore investigated whether plasma levels of renin and aldosterone differ between suicide attempters, non-suicidal depressive pati
To define fibre type grouping in terms of random and non-random arrangements of the two fibre types, type 1 (ST) and type 2 (FT), we adopted the measure of counting the number of "enclosed fibres". The statistical properties of the number of enclosed fibres, and the number and size of groups of enclosed fibres were studied in computer-simulated muscle cross-sections, using a model based upon hexag
This dissertation examines the labor market outcomes of a population of natives and immigrants in Sweden from 1968 and until 2001. Previous research has consistently pointed to the importance of an individual’s country of origin, without being able to fully explain why this is the case. The standard approach is to use the country of origin as a way to measure everything occurring prior to migratio
The propagation channel determines the fundamental basis of wireless communications, as well as the actual performance of practical systems. Therefore, having good channel models is a prerequisite for developing the next generation wireless systems. This thesis first investigates one of the main channel model building blocks, namely clusters. To understand the concept of clusters and channel chara
Introduction Emerging research indicates that integrated treatment of co-occurring post-traumatic stress disorder (PTSD) and substance use disorder can be effective among adolescents and young people. However, various barriers exist to young people accessing evidence-based treatments. Telehealth offers an opportunity to address these barriers and provide a scalable and accessible alternative to in
A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using 20.3 fb(-1) of proton-proton collision data at root s = 8 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectatio

Syftet med uppsatsen är att belysa transpersoners utsatthet och att blottlägga de normer om kön och sexualitet som bidrar till att personer som avviker från dessa utsätts för hot, våld och diskriminering. Studieobjekt utgörs av filmen The Danish Girl och de metodologiska verktygen har sin grund i en filmanalys. Undersökningens centrala tema handlar om vilka föreställningar om kön och sexualitet so
Entrepreneurs often face high levels of stress (Boyd & Gumpert, 1983; Shepherd, Marchisio, Morrish, Deacon & Miles, 2010) and stress has been found to affect a team’s performance (Driskell, Salas & Johnston, 1999). At the same time, private equity investors are a common source to gain external funding, while being known for their value-added roles as well as potential risks (De Clercq,
