A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of 8 TeV collected with the ATLAS detector at the Large Hadron Collider. The samples used for this search were collected in 2012 and correspond to integrated luminosities in the range 19.5-20.3 fb
Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb(-1) of pp collision data at root s = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from >= 6 to >= 9 jets. No evidence is foun
The purpose of this thesis was to investigate hardware usability issues on modern mobile phones, in order to form design guidelines and eventually a concept design proposal focusing on high usability. The project had a Universal Design focus, and the goal was to design a concept that fits as many users as possible. Initially a market analysis was performed in order to find out what phones focusin
The Swedish National Laboratory MAX-lab contains a facility for production of bremsstrahlung photons for photonuclear experiments. A so called "tagging technique" allows for a determination of the energy of the individual photons via a spectrometric measurement of the energy of the corresponding electron. Some of these photons are lost in a collimation process. The fraction of photons in
Sexual and Reproductive Health and Rights (SRHR) is suggested to be solved by policies and action plans. However, post-structural scholars argue that discourses shape policies, and their solutions. The policy discourse on women with disabilities’ SRHR needs has not been given much attention, especially in the context of Africa. Therefore, this study questions how SRHR is represented in relation to
The discovery of the Higgs boson h in 2012 further confirmed the remarkable accuracy of the Standard Model (SM). Despite this, some compelling excesses in multi-lepton final states were recorded in both major runs of the Large Hadron Collider (LHC). The excesses can be explained by the introduction of a model where a heavy boson X decays into a SM Higgs boson h and a singlet scalar S with Higgs-li
In pursuit of energy efficiency and sustainable development, goals have been set by the EU and Sweden to improve the energy performance of buildings and reduce their environmental impact. Renovating the existing building stock is a path to achieving the energy and climate goals. This study investigates and analyses various retrofitting options for multifamily residential buildings in Skåne, Sweden
With an increase in temperature (T) and a change in precipitation (P) patterns due to climate change, global conditions for tree growth are changing and shifting. While some areas experience an increase in P, favoring tree growth, many regions are also predicted to show a decrease in P, leading to trends of desertification. This study examines the projected climate change in Nigeria, located in Su
Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. This study reports the foraminiferal survival behavior, and geochemical tr
Thailand’s food retail sector was rapidly transformed during the past decade. This change was resulted in a substantial reduction in the number of traditional retailers as well as the sales of the existing ones while the number of modern retailers and their sales accelerated progressively. However, this can be seen as the must-happened transformation process, as it was also seen in other developed
Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. In this work, the sorption and diffusion of water vapor are investigated through gravimetric experiments and numerical simulations. The mixture theory framework is adopted to d
Human-wildlife conflicts threaten the existence of many species worldwide. Large carnivores are often involved in such conflicts due to their diets and expansive home ranges. In Finland, wolf (Canis lupus) is one of such conflict-prone species. The wolf conflict is a multifaceted issue stemming for instance from fears, damages to domestic animals, competition for game and opposition of EU wildlife
A search for the Standard Model Higgs boson has been performed in the H -> WW -> lvjj channel using 4.7 fb(-1) of pp collision data recorded at a centre-of-mass energy of root s = 7 TeV with the ATLAS detector at the Large Hadron Collider. Higgs boson candidates produced in association with zero, one or two jets are included in the analysis to maximize the acceptance for both gluon fusion and weak
Elevated cystatin C in blood reflects impaired glomerular filtration rate (GFR), but current cystatin C assays, based on polyclonal antibodies and immunoturbidimetric or nephelometric detection, have several limitations. We evaluated a new immunoassay based on monoclonal antibodies in samples from patients with and without chronic kidney disease (CKD). The study enrolled 170 men without known CKD
Many extensions of the Standard Model predict the existence of charged heavy long-lived particles, such as R-hadrons or charginos. These particles, if produced at the Large Hadron Collider, should bemoving non-relativistically and are therefore identifiable through the measurement of an anomalously large specific energy loss in the ATLAS pixel detector. Measuring heavy long-lived particles through
A search for a massive [Formula: see text] gauge boson decaying to a top quark and a bottom quark is performed with the ATLAS detector in [Formula: see text] collisions at the LHC. The dataset was taken at a centre-of-mass energy of [Formula: see text] and corresponds to [Formula: see text] of integrated luminosity. This analysis is done in the hadronic decay mode of the top quark, where novel jet
A search for new phenomena in events featuring a high energy jet and large missing transverse momentum in proton-proton collisions at root s = 7 TeV is presented using a dataset corresponding to an integrated luminosity of 33 pb(-1) recorded with the ATLAS detector at the Large Hadron Collider. The number of observed events is consistent with the Standard Model prediction. This result is interpret
Knowledge about subjects who sustain hip fractures in middle age is poor. This study prospectively investigated risk factors for hip fracture in middle age and compared risk factors for cervical and trochanteric hip fractures. The Malmo Preventive Project consists of 22,444 men, mean age 44 years, and 10,902 women, mean age 50 years at inclusion. Baseline assessment included multiple examinations
Subjects with impaired glucose tolerance (IGT) are usually overweight and exhibit insulin resistance with a defective compensation of insulin secretion. In this study, we sought to establish the interrelation between insulin secretion and insulin sensitivity after oral glucose in non-obese subjects with IGT and we also examined this interrelation in relation to the 2 main incretins, glucagon-like
