Gymnasiets laborationsundervisning i fysik – Vad påverkar lärares val av laborationer?

What factors influence Swedish upper secondary teachers' laboratory teaching in physics? This is an issue raised by the curriculum reform of 2011 in Sweden. In this study, 17 teachers at four different upper secondary schools discussed their laboratory teaching in focus group interviews. Based on an analysis of these interviews, a supplementary survey of 66 teachers was conducted. Logic of events

Perigenital necrotizing soft tissue infection caused by Aerococcus urinae

Aerococcus urinae can cause severe invasive infections emanating from the urinary tract especially in older males with comorbidities. Here we describe a case of an 80 year-old man with multiple comorbidities presenting with a peri-penile abscess and signs of severe infection. Upon incision A. urinae was isolated in pure culture and the infection was cured by a combination of drainage and antimicro

Assessment of cognition in ageing. Investigating internal validity, occurrence and reversion of Mild Cognitive Impairment. Data from the general population study “Good Aging in Skåne”

Bakgrund Med en snabbt växande äldre populationsgrupp kommer även andelen med kognitiva störningar, som demens, att växa. Det är således nödvändigt med forskning på kognition och åldrande. Denna avhandling, genom fyra delarbeten, redogör för testledareffekter vid kognitionsmätningar och hur yngre födelsekohorter (generationer) presterar bättre än äldre på kognitionstester. Den kommer även förklaraGiven a growing population of older adults and the common occurrence of natural as well as pathological cognitive decline, i.e. dementia, there is a need to better understand how to accurately measure and classify level of cognitive functioning. Both using multiple test administrators to collect cognitive data and what year the participant is born (birth cohort effects) can influence participants’

Influence of EVA, PVB and Ionoplast Interlayers on the Structural Behaviour and Fracture Pattern of Laminated Glass

Architectural trends increasingly challenge material producers and engineers to create sustainable, renewable and innovative laminated glass products that combine multiple functions as in, for example, glass railings with solar cells, curved laminated glass, floors with light emitting diodes that serve as multimedia screens. All new tendencies require the development of interlayers for laminated g

Penetration of Poisons Along the Monolith Length of a V2O5/TiO2 Diesel SCR Catalyst and Its Effect on Activity

Abstract: Catalysts used for selective catalytic reduction of NOx on diesel engines were deactivated for 890 and 2299 h in the exhausts from a diesel engine running on Swedish diesel fuel mark 1. The deactivated catalytic monoliths (100 mm long) were cut in 10 mm pieces along their axis and were characterized by physicochemical methods as well as by determination of the activity in the reduction o

Online representations of nursing-home life in Sweden : Perspectives from staff on content, purpose and audience

The article is based on a study of how social media and other types of online representations of nursing homes are described by staff. The study proceeds from a qualitative thematic analysis of 14 interviews with nursing-home representatives. The article addresses a key finding that was apparent in the interviews: the online representations' form and content were adjusted to fit the demands of res

Global inorganic nitrogen dry deposition inferred from ground- and space-based measurements

Atmospheric nitrogen (N) dry deposition is an important component in total N deposition. However, uncertainty exists in the assessment of global dry deposition. Here, we develop empirical models for estimating ground N concentrations using NO 2 satellite measurements from the Ozone Monitoring Instrument (OMI) and ground measurements from 555 monitoring sites. Global patterns and trends in the flux

Feeling controlled or being in control? Apps for self-management among older people with neurological disability

Purpose: The aim of this paper was to describe how people living with a neurological disability such as multiple sclerosis, Parkinson’s disease and stroke reason regarding using apps to facilitate self-management in everyday life.Material and methods: A qualitative research approach with a focus group methodology was used. The sample comprised 16 participants, 11 men and 5 women, with an average a

Changes in temperature sensitivity and activation energy of soil organic matter decomposition in different Qinghai-Tibet Plateau grasslands

Qinghai-Tibet Plateau grasslands are unique geographical regions and store substantial soil organic matter (SOM) in the soil surface, which make them very sensitive to global climate change. Here, we focused on three main grassland types (alpine meadow, steppe, and desert) and conducted a soil incubation experiment at five different temperatures (5, 10, 15, 20, and 25°C) to investigate SOM decompo

Spatial and decadal variations in inorganic nitrogen wet deposition in China induced by human activity

Atmospheric nitrogen (N) deposition, an important component in the global N cycle, has increased sharply in recent decades in China. Here, we constructed national-scale inorganic N wet deposition (N dep) patterns in China based on data from 280 observational sites and analysed the effects of anthropogenic sources and precipitation on N dep. Our results showed that the mean N dep over China increas

Cerebrospinal fluid neurogranin in an inducible mouse model of neurodegeneration : A translatable marker of synaptic degeneration

Synapse impairment is thought to be an early event in Alzheimer's disease (AD); dysfunction and loss of synapses are linked to cognitive symptoms that precede neuronal loss and neurodegeneration. Neurogranin (Ng) is a somatodendritic protein that has been shown to be reduced in brain tissue but increased in the cerebrospinal fluid (CSF) of AD patients compared to age-matched controls. High levels

Improving the reporting quality of intervention trials addressing the inter-individual variability in response to the consumption of plant bioactives : quality index and recommendations

Purpose: The quality of the study design and data reporting in human trials dealing with the inter-individual variability in response to the consumption of plant bioactives is, in general, low. There is a lack of recommendations supporting the scientific community on this topic. This study aimed at developing a quality index to assist the assessment of the reporting quality of intervention trials

Mirror, mirror on the wall, who's the innovator after all? : An explorative study of a management-initiated employee innovation process

Today, the innovation arena is open to a wider range of participants than previously acknowledged. One specifically neglected group of innovators in traditional innovation studies is non-R&D and non-managerial employees, also referred to as ‘ordinary’ employees by the existing body of literature on employee-driven innovation (EDI). These employees have no formal innovation function, meaning th

Association Between Vitamin D, Frailty, and Progression of Frailty in Community-Dwelling Older Women

CONTEXT: Vitamin D (25OHD) is involved in many physiological functions that decline with age, contributing to frailty and increased risk for negative health outcomes. Whether 25OHD is a long-term risk marker for frailty over a longer time and whether it is consistent with advancing age is unclear. OBJECTIVE: To investigate the association between 25OHD and frailty in older women followed for 10 ye

A quick test of cognitive speed can predict development of dementia in Parkinson’s disease

Parkinson’s disease (PD) patients frequently develop cognitive impairment. There is a need for brief clinical assessments identifying PD patients at high risk of progressing to dementia. In this study, we look into predicting dementia in PD and underlying structural and functional correlates to cognitive decline in PD. We included 175 patients with PD, 30 with PD dementia, 51 neurologically health

Quality of life in chronic conditions using patient-reported measures and biomarkers : a DEA analysis in type 1 diabetes

BACKGROUND: A chronic disease impacts a patient's daily life, with the burden of symptoms and managing the condition, and concerns of progression and disease complications. Such aspects are captured by Patient-Reported Outcomes Measures (PROM), assessments of e.g. wellbeing. Patient-Reported Experience Measures (PREM) assess patients' experiences of healthcare and address patient preferences. Biom

Intralesional EBV-DNA load as marker of prognosis for nasopharyngeal cancer

Nasopharyngeal cancer (NPC) is associated with the Epstein-Barr virus (EBV). The clinical presentation and prognosis of NPC is well described, but not in relation to intralesional EBV-DNA load. In a retrospective design, 48 patients with NPC were examined. Patient history was re-evaluated, and diagnostic biopsies were re-examined. Furthermore, intralesional EBV-DNA was quantitated and HPV status d
