UV-B treatment of thylakoid membranes or fractions derived from them accelerates the first rise (Fo---Fi phase) of variable fluorescence and slows down the second (Fi---Fm) rise. This can be observed for all membrane fractions but to different extents. The grana fraction is affected more by the UV-B treatment than are the intact thylakoids and the stroma lamella fraction. An exogenous electron acc
Calculated absorbed dose distributions from tangential irradiation of the breast have been compared with TLD measurements in a anthropomorfic body-shaped phantom which has gone through all phases of the radiation treatment planning cycle, including mapping of electron densities with a CT scanner, simulation of beam set-up and several treatments with an accelerator. The absorbed doses, measured in
Background: The Swedish Program for health surveillance of preschool children includes screening of language and communication abilities. One important language screening is carried out at age 4 years as part of a general screening conducted by health nurses at child health centres. The instruments presently in use for this screening mainly focus on expressive phonology. This may result in both ov
Suggestive QTL affecting raw firmness scores and average Instron force, tenderness, juiciness, and chewiness on cooked meat were mapped to pig chromosome 2 using a three-generation intercross between Berkshire and Yorkshire pigs. Based on its function and location, the calpastatin (CAST) gene was considered to be a good candidate for the observed effects. Several missense and silent mutations were
The proportion of hand injuries in Swedish children is the second highest in relation to other parts of the body. The incidence of hand injuries in these children has not yet been estimated. In addition, aetiologies, injury patterns and costs among Swedish children have not been presented on a regional or national level. Also, very few studies have focused on hand injuries within specific ages for
The paper compares PM10 concentrations in railroad environments with EU air quality standards and characterizes particle concentrations and particle properties in relation to train traffic. The results show that PM10 concentrations in ground-level railroad environments do not exceed the EU directive 24-h limit value, while on the platforms of the two subterranean stations PM10 concentrations were
The small nuclear genome of the pufferfish, Fugu rubripes (order Tetraodontiformes), makes this species highly interesting for genome research. In order to establish the phylogenetic position of the Tetraodontiformes relative to other teleostean orders that might also have a reduced nuclear genome size, we have sequenced the mitochondrial (mt) genome of the pufferfish. The gene order, nucleotide c
Today, driver support tools intended to increase traffic safety, provide the driver with convenient information and guidance, or save time are becoming more common. However, few systems have the primary aim of reducing the environmental effects of driving. The aim of this project was to estimate the potential for reducing fuel consumption and thus the emission of CO, through a navigation system wh
Currently, the use of metal-backed tibial components is more common than the use of all-polyethylene components in total knee arthroplasty. However, the available literature indicates that all-polyethylene tibial components are not inferior to the metal-backed design. We hypothesized that there would be no difference in the ten-year survival rate between all-polyethylene and metal-backed tibial co
only using electric-dipole forbidden emission lines, in what we label forbidden-line spectroscopy, we identified several energy levels in cadmium-like tungsten, W26+. The spectrum was recorded at the Shanghai permanentmagnet electron beam ion trap in the visible region. The identifications were supported by large-scale multiconfiguration Dirac-Hartree-Fock calculations which involved careful inves
We studied the evolutionary history of the Parmeliaceae (Lecanoromycetes, Ascomycota), one of the largest families of lichen-forming fungi with complex and variable morphologies, also including several lichenicolous fungi. We assembled a six-locus data set including nuclear, mitochondrial and low-copy protein-coding genes from 293 operational taxonomic units (OTUs). The lichenicolous lifestyle ori
In this thesis I have investigated pauses in writing in word-internal contexts and clause boundaries. I have been looking at the differences between 15-year-olds and adults with dyslexia and been focusing on how many pauses and how much pause time they have in these contexts. People with dyslexia have difficulties coding words, which mean that they are bad spellers and readers. Normally we automat
Populärvetenskaplig sammanfattning: En verksamhet eller åtgärd kan ha stor inverkan på människor, djur, växter, mark, vatten, luft, klimat, landskap och kulturmiljö. För att fatta bästa möjliga beslut om en projekt-ut-formning som tar hänsyn till konsekvenserna för olika berörda miljövärden åter-finns kravet på miljökonsekvensbeskrivning, MKB, i svensk lagstiftning. Syftet med en MKB är att identiAn activity or a measure might have a great impact on people, animals, plants, soil, water, air, climate and landscape. In order to describe the direct and indirect effects an intended activity might have an Environmental Impact Assessment (EIA) must be carried out. This demand is regulated in Swedish legislation and makes it possible to achieve as small impact on the environment as practicable. A
Purpose: To investigate the change in proportion of high-volume cataract surgeons during the period 2007 to 2016 and determine the impact of operation volume per surgeon and clinical unit on the rate of capsule complications. Design: Retrospective, register-based study. Participants: Patients undergoing and surgeons performing cataract surgery at Swedish ophthalmologic departments 2007–2016. Metho
This paper presents a preliminary method developed for improved decision-support based on probabilistic methods for risk assessment using building performance simulations. The aim of the method is to support the decision-maker in all stages of the building process when deciding on the design of a building by including uncertainties and quantifying; the probability of fulfilling objectives; energy
Progressive myoclonic epilepsies (PMEs) comprise a group of rare disorders of different genetic aetiologies, leading to childhood-onset myoclonus, myoclonic seizures and subsequent neurological decline. One of the genetic causes for PME, a mutation in the gene coding for Golgi SNAP receptor 2 (GOSR2), gives rise to a PME-subtype prevalent in Northern Europe and hence referred to as North Sea Progr
Background: Neuropsychiatric symptoms (NPS) are prevalent in the early clinical stages of Alzheimer’s disease (AD) according to proxy-based instruments. Little is known about which NPS clinicians report and whether their judgment aligns with proxy-based instruments. We used natural language processing (NLP) to classify NPS in electronic health records (EHRs) to estimate the reporting of NPS in sym
INTRODUCTION: The incidence of pancreatic cancer is around 5 in 100,000, and the 5-year survival is poor. Pancreatic cancer patients have a high disease-specific burden of symptoms, and palliative chemotherapy has varying side effects. The American Society of Clinical Oncology (ASCO) suggests integrating specialized palliative care (SPC) with standard oncological treatment for pancreatic cancer pa
Recognizing that two elements within a sequence of variable length depend on each other is a key ability in understanding the structure of language and music. Perception of such interdependencies has previously been documented in chimpanzees in the visual domain and in human infants and common squirrel monkeys with auditory playback experiments, but it remains unclear whether it typifies primates
Målet med strålbehandling är att leverera en tillräckligt hög stråldos för att skadacellerna i en cancertumör utan att skada omkringliggande friska celler. Olika typerav celler är olika känsliga för strålning vilket man måste ta hänsyn och idaggörs med datoriserad stråldosplanering. Vid dosplanering provas olika antal strålfältmed olika vinklar och intensitet forma stråldosen att täcka tumören utaRadiotherapy is one of the essential treatments used in the fight against cancer. The goal of radiotherapy is to deliver a high dose of ionising radiation to the tumour volume and at the same time minimise the effect on healthy tissue by reducing the radiation to critical organs. This contradiction is challenging and has been driving the research and development of the treatments.Over the last two
