The results of a search for pair production of the lighter scalar partners of top quarks ((t) over bar (1)) in 2.05 fb(-1) of pp collisions at root s = 7 TeV using the ATLAS experiment at the LHC are reported. Scalar top quarks are searched for in events with two same flavour opposite-sign leptons (e, mu) with invariant mass consistent with the Z boson mass, large missing transverse momentum and j
A search is performed for WH production with a light Higgs boson decaying to hidden-sector particles resulting in clusters of collimated electrons, known as electron-jets. The search is performed with 2.04 fb(-1) of data collected in 2011 with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at root s = 7 TeV. One event satisfying the signal selection criteria is observe
HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells) is the first member in a new family of protein-lipid complexes with broad tumoricidal activity. Elucidating the molecular structure and the domains crucial for HAMLET formation is fundamental for understanding its tumoricidal function. Here we present the low-resolution solution structure of the complex of oleic acid bound HAMLET, derived
Populärvetenskaplig sammanfattning Morgondagens energi Vind-, och vattenkraft tillsammans med solenergi är de enda energikällorna vi har som inte leder till avfall som ökar växthuseffekt eller avfall som vi inte kan göra oss av (från t ex kärnkraftverk). Men solpanelerna som finns idag för kommersiellt privat bruk ligger på en effektivitet kring 15%. Att utveckla nya molekyler som kan omvanlda solThe aim of the study was to theoretically investigate if a proton coupled electron transfer (PCET) was feasible for a molecular system consisting of a light harvesting complex, ruthenium(tris-2,`2-bipy)2+, with different organic moieties serving as PCET (proton coupled electron transfer) relays. These light harvesting complexes are also sometimes referred to as dyes. By studying the energy levels
This study aims to add new knowledge to our understanding of poverty as a multidimensional phenomenon and focuses on the links between poverty and gender norms and practices. The overall research question that this study is concerned with is about the effect of self-help group participation on women’s self-perceptions of options, their access to social, economic and cultural capital, and subsequ
The aim of this thesis is to present experiences and lessons learned from the initial implementation process of the rating system STARS at Washington University in St. Louis: mainly the strengths/opportunities can be used to overcome the weaknesses/threats that the STARS implementation may entail. Strengths and opportunities such as increased student involvement in processes such as assessing sust
The purpose of this study is to investigate the difference in consumer perception of and purchasing behaviour towards two different categories of companies (“traditional” fast fashion brands and “sustainability-driven” sustainable/slow fashion brands) and their environment-related CSR activities in the global fashion industry. The primary objectives of this paper are to determine if “sustainabilit
In recent years, corporate branding and its potential benefits on brand performance has become an increased area of interest for both researchers and communication professionals. This study aims to deepen and increase knowledge about the concept of corporate brand identity and its influence on brand performance in the communications sector and answer the research question; How do the dimensions of
Title: A framework for understanding the cost of servicing customers when orders are at risk of late delivery – A case study at Tetra Pak Authors: Simon Lundqvist and Alexander Olsson Supervisors: Eva Berg, Division of Industrial Management and Logistics, Lund University Michael Hultberg, Global supply planning manager, Tetra Pak Examiner: Jan Olhager, Division of Industrial Management and Logisti
In this paper, we investigate the long-term post-event stock return performance of companies operating in the IT sector and listed on NASDAQ Stockholm by using 78 mergers and acquisitions deals performed in the 2009 – 2013 period. We apply the event study methodology, focusing on the buy-and-hold abnormal returns approach. Stock return performance is analyzed in comparison to the Swedish general m
Syftet med denna studie är att ge klarhet i adoptionsprocessen av en plattformsbaserad affärsstrategi för ett etablerat företag genom en fallstudie i den diskreta tillverkningsindustrin. Studien avser att bidra till den nuvarande begränsade litteraturen om affärsstrategiska och organisatoriska följder för etablerade företag när dessa implementerar en plattformsbaserad affärsstrategi. Därav är fors
Objective: Classification criteria for early-stage symptomatic knee osteoarthritis (EsSKOA) should discriminate individuals with EsSKOA from those with other causes of knee symptoms. We sought to identify conditions in the differential diagnosis of EsSKOA in adults with knee symptoms. Design: We conducted an online survey of clinicians. Those consulting monthly on at least five people with undiagn
BackgroundThe essential trace elements copper and zinc, and their ratio (copper/zinc), are important for maintaining redox homeostasis. Previous studies suggest that these elements may impact breast cancer survival. However, no epidemiological study has so far been conducted on the potential association between copper and copper/zinc levels and survival after breast cancer diagnosis. In this study
According to many scholars America's soft power is in decline, a power resource whose importance has been increasing in world politics. This makes it interesting to examine if there is a difference between how Democratic and Republican administrations wield their soft power. This thesis is a hypothesis-testing study and the purpose is to test the hypothesis that Democratic administrations, to
This thesis is a case study of a Spanish castle called Aljafería. The objective of the study was to develop the mediation of this particular castle and to construct a research design that could be used to develop the mediation of other architectural heritage visitor attractions. The research design emerged during the course of the case study, using a grounded method perspective. The most dominant
Nanowire growth enables creation of embedded heterostructures, where one material is completely surrounded by another. Through materials-selective post-growth oxidation it is also possible to combine amorphous oxides and crystalline, e.g. III-V materials. Such oxide-embedded structures pose a challenge for compositional characterization through transmission electron microscopy since the materials
BackgroundLow concentrations of serum selenium (Se) and its main transporter selenoprotein P (SELENOP) are associated with a poor prognosis following breast cancer diagnosis. Recently, natural autoantibodies (aAb) with antagonistic properties to SELENOP uptake have been identified in healthy subjects, and in patients with thyroid disease. Given the potential transport disrupting properties, we hyp
Introduction: Rates of delivery by cesarean section have gradually risen in many parts of the world, and it is regarded as a safe surgical procedure with expanded indications. We assessed maternal complications within 6 weeks postpartum after planned cesarean section and after planned vaginal delivery among patients without medical indication for cesarean section. Material and methods: This was a
Background: The combination of diphenylcyclopropenone (DCP) and anthralin may demonstrate synergistic effects in the treatment of chronic extensive alopecia areata (AA).Objective: The objective of the study was to compare the efficacy of the combination therapy of topical DCP and topical 0.5% anthralin versus topical DCP alone for the treatment of chronic extensive AA.Materials and Methods: Ten pa
