During March 2020 a large-span arena, Tarfalahallen, collapsed. The main load-bearing girders with a 54 m span were high and slender glulam trussed beams, supported from below by a cable system via vertical struts. Investigations concluded that the failure was initiated by out-of-plane buckling of the struts and slender beam, in spite of lateral stabilization by steel roof sheeting at the top edge
Objective: The purpose of the study was to examine associations between self-esteem and symptoms of anxiety and depression among young adults who lost a parent to cancer. Methods: Older adolescents and young adults, aged 16 to 28 years, who had lost their parent to cancer and had accepted an invitation to join a support group, completed a questionnaire 5 to 8 months after the loss and a similar qu
Background/Objectives: Motor impairment induced by traumatic brain injury (TBI) may be mediated through changes in spinal molecular systems regulating neuronal plasticity. We assessed whether a focal controlled cortical impact (CCI) TBI in the rat alters expression of the Tgfb1, c-Fos, Bdnf, and Gap43 neuroplasticity genes in lumbar spinal cord. Approach/Methods: Adult male Sprague-Dawley rats (n
The concept of an innovation system is used to understand how innovation contributes to economic growth. However, innovation systems do not evolve evenly in different parts of the world. This paper contributes to the ongoing debate on the emergence of innovation systems in the context of developing countries. It uses the Rwandan case, where agriculture is a dominant socio-economic sector with high
In this paper, I briefly present my doctoral thesis research proposal. Recognizing that information has long been an important asset for any organization, I wish to explore in depth the management and use of information in contemporary information-intensive organizations such as academic libraries. Additionally, this research proposal emerges out of recognition that the academic library is a dynam
Ge and Si semiconductor nanoparticles encapsulated in oxide layers were prepared by the inert gas condensation method. High-resolution electron microscopy and energy dispersive X-ray spectrometry showed the formation of the core-shell structures with a size below 10 nm. The optical absorption spectra of Ge showed the band edges at higher energy compared to the ordinary Ge element. Photoluminescenc
INTRODUCTION: The aim was to investigate psychiatric health care utilization two years before death by suicide among individuals with previous suicide attempts (PSA) compared with those without (NSA).METHOD: A retrospective population-based cohort study was conducted including 484 individuals who died by suicide in Sweden in 2015 and were in contact with psychiatric services within the two years p
BackgroundSocial and geographical inequity in access to primary healthcare is an ongoing concern in Sweden. Digital care can potentially decrease geographical inequity. This study aimed to evaluate how urbanicity affects the utilization of a public digital primary healthcare service - PHC Online.MethodsWe performed an ecological cross-sectional study of 4,482 PHC Online visits grouped by 83 public
In Sweden, approximately 1,200 individuals die by suicide annually. Inpatient suicide is considered rare, but death by suicide still occurs when admitted to a psychiatric hospital. This study was part of a national retrospective project covering data from all patients' medical records for the 2 years before death by suicide in 2015. In this study, 41 patients who died by suicide while being admitt
AbstractThis study investigates the establishment and significance of United Nations (UN) Day, October 24, in Swedish primary and secondary schools from 1948 to 1963. This article conceptualizes the celebrations as knowledge rituals, educative events that foreground practices of knowledge-sharing, reinforcing social bonds and enhancing collective understanding. UN Day knowledge rituals combined ceThis study investigates the establishment and significance of United Nations (UN) Day, October 24, in Swedish primary and secondary schools from 1948 to 1963.This article conceptualizes the celebrations as knowledge rituals, educative events that foreground practices of knowledge-sharing, reinforcing social bonds and enhancing collective understanding.

BACKGROUND: Preeclampsia is a hypertensive pregnancy disorder marked by endothelial damage. Healthy endothelium is covered by a protective glycocalyx layer, which, when degraded, releases detectable products into the blood. Sphingosine-1phosphate (S1P) is a cardiovascular biomarker involved in glycocalyx preservation, linked to placentation and preeclampsia development. The study aimed to test the
Airborne depth sounding lidar has proven to be a valuable sensor for rapid and accurate sounding of shallow areas. The received lidar pulse echo contains information of the sea floor depth, but also other data can be extracted. We currently perform work on bottom classification and water turbidity estimation based on lidar data. In this paper we present the theoretical background and experimental
Background: Multiple clinical practice guidelines and head computed tomography decision rules exist for emergency department (ED) triage of children with traumatic brain injury (TBI). These vary in structure, aim, target cohort, and outcomes, yet are used clinically in similar populations. We compared important clinical and practical characteristics of all major guidelines in a large, real-world p
Retrieving episodic memories often involves reconstructing both their semantic content and the emotional context in which they occurred. However, the neural mechanisms that differentiate these forms of reinstatement remain poorly understood. This event-related potential (ERP) study examines how semantic category and emotional valence are reinstated during memory retrieval.Seventy participants enco
This qualitative study explores the existential dimensions of youths’ lived experiences in residential care through an existential – phenomenological approach. Based on in-depth interviews and participant observations with 16 youths in Swedish residential care, the study investigates how young people navigate existential concerns such as freedom, anxiety, and meaning within an institutional contex
In the degree that costs and demand of crude oil rise, diminish the economical disadvantages for alternative Diesel fuels, resulting in a variety of feasible substitutes. Diesel fuel substitutes have deviating exhaust emissions from conventional fuel. The methyl ester of rapeseed oil (known as RME/Biodiesel) is receiving increasing attention as an alternative fuel for Diesel engines. RME is a non-
Background: The incidence, aetiology, and outcome of unplanned intensive care unit admission after elective colon cancer surgery remain unclear. This study investigated the incidence of, and factors associated with, unplanned intensive care unit admission following elective colon cancer resection in Sweden. Methods: This nationwide retrospective registry study included adult patients undergoing el
In this thesis two processes have been modeled and controlled, namely the plate thickness control and the slab temperature control. The classical solution for the thickness control problem can't handle asymmetric hardness variations and the estimation of the controlled output introduces stability problems. A nonlinear multivariable model for the thickness control system is derived. The parameters
This study investigates the role of political journalism in EU constitution-making. More specifically, we ask whether political journalists take an active role in shaping public preferences and opinion on European integration. An analytical framework is developed distinguishing between the critical and the representative function of media opinion-making. Journalists are found to interfere with the
