Objective: To analyze the distribution of 3 collagen types in healthy tympanic membranes, during healing of a perforation, and during infection. Design: Immunohistochemical study of collagen types I, II, and III in the tympanic membranes of healthy rats as well as during healing of a perforation and in the presence of infection with Streptococcus pneumoniae at various time points. Setting: Laborat

This thesis explores the view of business related and historical records in 22 small and medium-sized companies in Sweden. According to Swedish law, small and medium-sized companies must keep business related records for a certain period of time. The keeping of records of historical value are on the other hand an activity based on free choices and does not answer under any law. The records of smal

Recent research on the Book of Psalms has been dealing intensively with issues relating to its so called “final shape." Proceeding from, among others, an influential dissertation by Gerald H Wilson, scholars have argued that the collection, as it now stands, is “more than the sum of its parts” (so e.g. McCann). Although such a notion is fairly straight forward on a conceptual or general level, it

Background: Existing research shows that older people with severe mental health problems need different forms of support in daily life and in the community to lead an active and meaningful life. A common form of support for people with severe mental health problems in Sweden is attendance at community-based day centres (DCs). However, knowledge of staff and managers’ experiences of how people agei

In this chapter, focus is on the period 1945-1960 and the discussion is divided into three thematic sections: First, macro-economic structures including growth trends and the composition of the economies. Second, colonial budgets including state finance, fiscal capacity, and economic policy. Third, changes in occupations, incomes, and living standards primarily for the African subjects. The text p

Atmospheric trace gas measurements can be used to independently assess national greenhouse gas inventories through inverse modeling. Atmospheric nitrous oxide (N2O) measurements made in the United Kingdom (UK) and Republic of Ireland are used to derive monthly N2O emissions for 2013–2022 using two different inverse methods. We find mean UK emissions of 90.5 ± 23.0 (1σ) and 111.7 ± 32.1 (1σ) Gg N2O

A brain-computer interface (BCI) is a real-time system that converts a user’s brain activity into commands, enabling control over applications such as moving a cursor on the screen. This conversion is made possible by machine learning techniques and other algorithms. Historically, BCI research has focused on the analysis of brain signals offline. However, increasing computational power and algorit

Recent droughts from 2017 to 2020 induced significant stress on woodland canopies across eastern Australia, resulting in widespread tree browning and mortality. However, the trajectory of post-drought recovery remains unclear, with uncertainty about whether canopy conditions are improving or continuing to decline. Identifying the key local environmental and climatic factors influencing drought-ind

Time-varying signals, such as sound waves, low-frequency vibrations from the earth, or electrical impulses in the human body, are often non-stationary, meaning their characteristics change over time. Because of this, standard spectral analysis methods, which assume stationary signals, cannot be used for analyzing such signals, as they discard the time-varying dynamics. This necessitates methods fo

By applying a novel approach to evaluate photofragmentation laser-induced fluorescence (PFLIF) imaging, experimental quantitative information on the temporal in-cylinder distribution of hydrogen peroxide (H2O2) in a homogeneous charge compression ignition (HCCI) engine was extracted. The results from PFLIF were then compared to those obtained from chemical kinetics simulations using computational

Popular Abstract in Swedish En av de viktigaste frågeställningarna inom molekylär genetik är hur uttrycket av människans ca 30-40 000 gener regleras i tid och rum. En typ av reglering som är väldigt viktig är transkriptionell reglering och denna utövas av proteiner som kallas transkriptionsfaktorer. Dessa binder till specifika områden i DNA strängarna i närheten av genkodande regioner och kan däriNeuroblastoma is a childhood tumor derived from primordial neural crest cells. The tumor cells exhibit a phenotype similar to that of developing neuroblasts, which indicates that the tumor arises due to perturbed differentiation of the sympathetic nervous system. It is well established that transcription factors control the steps leading to neuronal differentiation, and a number of basic helix-loo

In the current global scenario, it is evident that global warming and climate change are primarily driven by emissions stemming from the utilization of fossil fuels. Yet, if we look around, most of what we see is made from or linked to fossil fuels and it clearly shows our over-dependency on fossil fuels and hence there is a significant need to develop alternate sources of energy and raw materials

This paper presents kinematic data on the cervical and upper thoracic spine, based on measurements made on 20 Scandinavian healthy, female volunteers, aged 22-58 years (mean age 40.4). The aim was to provide anatomical in vivo data, primarily intended as data for biomechanical modelling of the upper spine. Together with the measurements of standard anthropometric body dimensions, magnetic resonanc

Popular Abstract in Swedish Den nya stadens bibliotek Folkbiblioteket beskrivs ofta som en av våra mest omtyckta och uppskattade samhällsinstitutioner. Trots detta har både besöken och utlåningen av böcker minskat under senare år, filialer läggs ner och på många håll minskar personalstyrkan. I en tid när böcker kan köpas på bensinmacken och mycket av den information vi söker kan hittas på nätet tyThis dissertation explores how perceived challenges and changing conditions for public libraries are translated and enacted in a local library setting. In 2008, Malmoe City Library, a public library situated in the third largest city of Sweden, initiated an ambitious strategy for renewal and change of their services. The strategy was given the name The Darling Library and expressed a vision to enf

Aims and objectives: To describe the experiences of participation in perioperative care of 8- to 11-year-old children. Background: All children have the right to participate in decisions that affect them and have the right to express their views in all matters that concern them. Allowing children to be involved in their perioperative care can make a major difference in terms of their well-being by

A number of different intervention programmes have been described in the literature for caregivers of people with dementia, but the nature of intervention has varied widely. The aim of the present study was to evaluate the efficacy of psychosocial intervention on family caregiver's level of burden and satisfaction, and possible influence of the caregiver's relationship and health and the patient's

The degree of general applicability across Europe currently achieved with several forest succession models is assessed, data needs and steps for further model development are identified and the role physiology based models can play in this process is evaluated. To this end, six forest succession models (DISCFORM, ForClim, FORSKA-M, GUESS, PICUS v1.2, SIERRA) are applied to simulate stand structure

The DNA sequencing of a series of living organisms has elucidated many biological problems. But the internal atomic and electronic evolution of DNA remains to be mapped in detail. RNA and DNA now appear to be the prime determinants of biological evolution leading to the sudden appearance of novel organism structures and functions that emerge “ready made” as a surprise to the organism. This has bee

Background: A common complaint by people with tinnitus is that they experience that the tinnitus causes attention and concentration problems. Previous studies have examined how tinnitus influences cognitive performance on short and intensive cognitive tasks but without proper control of hearing status. Purpose: To examine the impact tinnitus and high-frequency hearing thresholds have on reading co

AbstractPhysical exhaustion can constrain human ascending work capacity and performance during emergency evacuation on stairs. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations during two different strategies: self-preferred pace in three different public stairways in the field, and controlled pace in a laboratory on a stair machin
