A search for exotic decays of the Higgs boson into a pair of spin-zero particles, H → aa, where the a-boson decay sin to b-quarks promptly or with a mean proper lifetime cτa up to 6 mm and has a mass in the range of 20–60 GeV, is presented. The search is performed in events where the Higgs boson is produced in association with a W or Z boson, giving rise to a signature of one or two charged lepton
The planetary changes associated with the Anthropocene, including climate change and extinction of species, pose severe threats to civilization, humanity, and the natural world as we know it. They also pose special challenges to the human imagination. To meet these challenges, climate change communicators use narratives. Nonfiction books intended for a general audience employ two radically differe

Experimental data on single file pedestrian movement has been analysed and implemented in a prototype movement model. The prototype model is developed to predict movement of persons based on a first principle approach using basic population data such as age, height, gender and response time to adapt the walking speed in a crowd. The experimental data provide the biomechanical information needed inExperimental data on single file pedestrian movement has been analysed andimplemented in a prototype movement model.

After the dissolution of the Soviet Union in 1991, Russia was in the crisis that affected every aspect of the state activity. Among other things, Russia had to enact its own legislation that could serve the establishment of a market economy. The crisis affected heavily the intellectual property rights (IPR) protection: Russia had no IPR laws and no relevant state agency. During 1992-1993, new Russ
This essay is investigating how ideas influence political decisions, more precisely how ideas influenced the founding of SIDA, Swedens foreign aid institution, in the 1960´s. The goal of the investigation is to show how these ideas mattered and to do that I analyze them by seeing how the can be seen as road maps and focal points. Road maps are supported by a causal belief and focal points define w
The purpose of this essay is to compare point of views from four different liberal scholars concerning multiculturalism and group recognition. As well as to investigate if there are any conflicts between liberal values like liberty, equality and self-determination. The material is based on Will Kymlicka, Susan Moller Okin, Joseph Raz and Chandran Kukathas ideas about liberalism, multiculturalism a
Kvantumkontraktet är en kontraktsform inom området för godstransporter till sjös uppbyggt av ett ramavtal omfattande den totala kontraktstiden och innefattande funktionen att den specifika skeppningen regleras i förhållande till den enskilda nomineringen av fartyg, den enskilda resan regleras på detta sätt av ett underliggande kontrakt (t ex ett rese-certeparti). Avtalskonstruktionen som sådan s

Background and purpose: National quality registries for stroke care operate under the assumption that the included patients are correctly diagnosed. We aimed to validate the clinical diagnosis of spontaneous intracerebral hemorrhage (ICH) in Riksstroke (RS) by evaluating radiological data from a large, unselected ICH population. Methods: We conducted a retrospective, multicenter study including al
The purposes of this article-based thesis are to explore and understand preaching as a practice in general, and the practice of preaching in digital culture and spaces in particular. Informed by the practice theory of Theodore Schatzki, it presents the results of a cross-case analysis of four different case studies of the practice of preaching in digital culture and spaces in Swedish protestant chThe purposes of this article-based thesis are to explore and understand preaching as a practice in general, and the practice of preaching in digital culture and spaces in particular.

Experience of out-of-home care (OHC) is associated with life-long vulnerability, and research indicates that parents with experiences of OHC are at higher risk of having their own children placed in out-of-home care. However, research on these parents is limited and lacks a resilience perspective. Here, we focused on parents with OHC experience as children but with custody of their own children (N
Anorectal malformations (ARM) are a spectrum of congenital malformations, specifically defined by the absence of a normal anal opening. These conditions are treated surgically by posterior sagittal anorectoplasty and, in cases with perineal fistulas, perineal skin advancement is required to cover the tissue defect. Complications involving wound dehiscence are frequent, and may be due to stretching
Cross-section measurements of top-quark pair production where the hadronically decaying top quark has transverse momentum greater than 355 GeV and the other top quark decays into ℓνb are presented using 139 fb−1 of data collected by the ATLAS experiment during proton-proton collisions at the LHC. The fiducial cross-section at s = 13 TeV is measured to be σ = 1.267 ± 0.005 ± 0.053 pb, where the unc
We present new estimates of the living standards among the rural labouring classes in Sweden from 1750 to 1900. Starting with a database of more than 1,000 probate inventories of rural, landless and semi-landless people from the years 1750, 1800, 1850 and 1900, we study the development for crofters in particular. In a sub-sample of 120 probate inventories we map in great detail the material items
During the last couple of decades, we have witnessed a proliferation of the project as an organizational solution in sectors as diverse as IT, housing, social services, education and culture. Despite a growing interest in the phenomenon, we know surprisingly little of how processes of public sector projectification unfold in practice, especially at local government level. This article uses an inst
This thesis will research the Iranian state influence on repression in Iraq. In particular, it is a case study that will explore the Iranian state influence, in the form of ideological and financial influence, on pro-government militias in Iraq between 2014 and 2020. The main pro-government militias to be studied are the Popular Mobilization Forces (PMF), who were formed after the emergence of the
Schools and libraries in Sweden strive to be inclusive of all groups in society, particularly people with disabilities. Both actors are responsible for making knowledge available to all, as knowledge is a necessary precondition for a democratic society that is both inclusive and well-functional. This study was carried out on behalf of the Svane and Hedda schools in Lund, which will be co-located
