Yet, there are many aspects of this topic that are still unexplored. This project aimed to optimize a method for analysis of the skin micro flora and the effect of skin care products on the skin micro flora, from sampling and sample preparation to analysis with quantitative polymer

In this work we have addressed the task of segmentation in skeletal scintigraphy images with deep learning models, where we research different approaches to convert convolutional neural networks designed for classification tasks to powerful pixel wise predictors. We explore different network architectures where two primary research paths have been followed. Firstly, an encoder-decoder architecture

In Sweden as well as in The Netherlands energy policy is increasingly aiming at extending the use of renewable sources. In accordance with the targets of the European Union, both countries have formulated national targets for the year 2020. For wind energy these targets are 30.0 TWh of electricity in Sweden and a total installed capacity of 10.0 GW in The Netherlands. Wind is an inflexible, variab

Rapporten är en del i kursen Brandteknisk riskvärdering som ges på brandingenjörsprogrammet vid Lunds Tekniska Högskola. Arbetet inleddes med ett studiebesök där de aktuella lokalerna studerades och information om det befintliga braThis report is an evaluation of the fire safety at Frejaskolan in Gnesta, Sweden. The report was preceded by a field trip to the school and the fire safety at the school was studied. A number of fire scenarios have been treated, and three were chosen for further analysis. To be able to make any judgements about the fire safety, estimation has been done by comparing the time needed for safe evacua

To be in the hospital as a patient is a special occurrence, and patients’ experiences often vary when it comes to care, specifically in relation to hospital staff. The purpose of this study was to examine patients’ and personnel’s experiences of the care in an orthopedic clinic and to explore causal factors that maybe are affecting the experience of care. The community, the organization of the hos

Reduced chemical kinetic mechanisms are essential for atmospheric chemistry modeling where the use of explicit kinetic schemes is too computationally demanding. By tailoring mechanisms to specific cases, the size of the mechanism can be kept small, without significant loss of accuracy in predictions of selected species’ concentrations. In the present work, we present small kinetic mechanisms tailo

Anthropogenic land cover change (ALCC) is the most important transformation of the Earth system that occurred in the preindustrial Holocene, with implications for carbon, water and sediment cycles, biodiversity and the provision of ecosystem services and regional and global climate. For example, anthropogenic deforestation in preindustrial Eurasia may have led to feedb

Nanotechnology is a collective definition referring to every technology and science which operates on a nanoscale. Nanoparticles have different properties than larger particles and these properties can be utilized in a wide spectre of areas such as in medicine, information technologies, energy production and storage, materials, manufacturing and environmental applications. Although nano-derived a

Domestic work is one of the oldest and most important occupations for many women in many countries. However, it is one of the occupations that are still undervalued and neglected. It is often regarded as unskilled because most women have traditionally been considered capable of doing the work. When paid, the work remains undervalued and poorly regulated. These days, it is also a global phenomenon

Nitrogen (N) availability is a powerful controller of soil carbon (C) cycling in temperate forests, affecting plant productivity and microbial activities. Enhanced rhizosphere input from increased plant productivity can stimulate the decomposition of native soil organic matter (SOM), termed the “priming effect”, with an effect size that is affected by N availability. Using soils from N-fertilizati

Aviation remains a problematic sector of the global economy in times of climate emergency. Grounded in the ideology of reconfiguration, we adopt a system transitions perspective to address high emissions leisure travel. Our focus falls on the marketing communications of airlines as a critical component in the prevailing sociotechnical regime. Thematic analysis of the e-mail marketing communication

Alzheimer’s disease is an aging related disorder of the mind, accountable for 60-80 percent of all cases of dementia. With its insidious progression and the decline of cognitive abilities, this disease is a major challenge for our society as a whole. This is because of the growing proportion of people living to advanced age and our current lack of capacity to prevent or even give effective symptom

Background: The use of remote services such as video consultations (VCs) has increased significantly in the wake of the COVID-19 pandemic. In Sweden, private healthcare providers offering VCs have grown substantially since 2016 and have been controversial. Few studies have focused on physicians’ experiences providing care in this context. Our aim was to study physicians’ experiences of VCs, focusi

Introduction: Fish β-parvalbumins are common targets of allergy-causing immunity. The nature of antibody responses to such allergens determines the biological outcome following exposure to fish. Specific epitopes on these allergens recognised by antibodies are incompletely characterised. Methods: High-content peptide microarrays offer a solution to the identification of linear epitopes recognised

Popular Abstract in Swedish "Tanken i rörelse" handlar dels om hur tanken sätts i rörelse av brus och dels om hur detta brus kan användas av hjärnan för att fånga upp visuell rörelse. Ofta betraktas brus som en störning, men detta arbete försöker visa att brus kan ha en viktig funktion i tankeprocessen. Arbetet vill visa hur våra tankar växer fram ur det bakgrundsbrus som alltid finns i hjärnan i The brain is not silent. Even in the absence of stimuli are the neurons activated every now and then in what is called "spontaneous" or "background activity" which provides a noisy background to the operation of the brain. This work shows how this noise can be utilized in the cognitive process. That is, rather than being treated as a nuisance, noise is given a functional role in the brain´s activi

The European spruce bark beetle ( Ips typographus L.) is a biotic disturbance that devastates forest environmental services, and its activities are exacerbated due to climate change. Accordingly, researchers seek workflows using remote sensing imagery for bark beetle detection in the early stage of the attack, enabling proactive management. Most previous studies attempted to detect attacks with pi

Quinoa (Chenopodium quinoa Willd.) is a pseudocereal originally grown in the Andean region of South America. This study focused on investigating the changes in phenolic profile and antioxidant capacity in white and red quinoa varieties after short-term fermentation with Lactiplantibacillus plantarum 299v®. During fermentation, pH and lactic acid formation were monitored every three hours until pH

Different societies regulate differently. Historically, social evolution has often been connected to technological innovations. The combustion engine took a central position in what later became known as the industrialized society, an urbanizing era of factories and production, on its hand following on the rural society tied to agriculture and trade. With each type of society comes a specific type

A hierarchical multi-scale model that couples a region of material described by discrete dislocation plasticity to a surrounding region described by conventional crystal plasticity is presented. The coupled model is aimed at capturing non-classical plasticity effects such as the long-range stresses associated with a density of geometrically necessary dislocations and source limited plasticity, whi

The oil crisis in the 1970’s made countries realize their dependence on oil; and with it a dependence of other countries. To be self-sufficient and to be able to decrease the impact of economic crises, such as the oil crisis, some countries have started searching for renewable alternatives for fossil fuels. In the same process the importance of saving energy has become another vital action towards
