With the growing pool of deposited protein structures, the need for structural analysis tools grows. In study of amino acid substitutions the variety of analysis tools is high; nevertheless, there is a lack of programs serving specific purpose, such as identifying if an amino acid substitution would cause a clash in the structure or not, given just the structure of the original protein. In this stAnalysing structural damage caused by changes in proteins In an organism, even only one single change of an amino acid can sometimes lead to disease, if the protein is a part of an important biological function. Because of that, it is important to study those changes and be able to predict if an amino acid substitution would cause harm. There are various ways a substitution can be harmful to a pr

Chronic obstructive pulmonary disease (COPD) is a progressive life-threatening disease that is significantly increasing in prevalence and is predicted to become the third leading cause of death worldwide by 2030. At present, there are no true curative treatments that can stop the progression of the disease, and new therapeutic strategies are desperately needed. Advances in cell-based therapies proTo date, bone marrow-derived mesenchymal stromal cells (MSCs) have been considered the golden standard among MSC cell-based therapies. However, the harvesting of bone marrow is a highly invasive procedure and the number of MSCs isolated is low, and it declines with increasing age. MSCs with immune-regulatory and regenerative properties can be isolated from many different tissues; however, bone mar

Popular Abstract in Swedish Many of the energy needs in today’s modern society are fulfilled by sources based on fossil fuels, including non-domestic oil and coal. It is well known that the increase in CO2 emission is the result of human activities, mostly fossil fuel consumption. The use of such fuels is unsustainable and has led to the phenomena such as climate change, political instability in sThe gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. The use of biomass gasification for energy purposes can help lower the net emissions of greenhouse gases,

Energy intensive industries (EIIs), producing the basic materials and products needed in society, contribute significantly to global emissions of greenhouse gases (GHGs). Motivated by the fear of carbon leakage, climate policy has so far treated the EIIs leniently with e.g. low carbon prices and/or free allocation of emission allowances.

Many bumblebee species are declining due to a loss of semi-natural habitats in agricultural landscapes resulting in diminished forage and nest sites. Anecdotal experience indicates that bumblebees nest in straw bales, but scientific evidence is lacking. We spent 250 h screening for bumblebee nests in 1255 straw bales and ten straw stacks belonging to 58 farms in two intensively farmed Swedish regi

Popular Abstract in English Look around and notice how many items have been manufactured or transported using petroleum-based products. In modern life, it is almost an impossible task to exclude them from our daily routine. They are present in plastics, cosmetics, cleaning products, medicaments, food, etc. To diminish our dependence on the demanded black liquid, a lot of research efforts have beenDepletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. Efficient processes for the conversion of pla

Infrared (IR) spectroscopy has many advantages over optical, one of which is allowing us to see through intergalactic dust, letting us probe deeper into space and dust-dense regions such as galactic centers. However the investigating the IR spectral range is a relatively new field, owing to recent developments in detector technology, and stellar parameter determination in IR is not well researchedMillions of stars litter the night sky, and our understanding of how they were born is still developing. These burning orbs of gas are so far away that even the light they give off takes years to arrive to us on Earth. So how are we to measure anything about them if sending any equipment to their distant locations is unimaginable? Since the days of Newton, the only way we have been able to say any

This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. The region between these two contacts is a junction, being Laser Activated Electronics Transistors are often considered the most revolutionary electrical devices of this century, attributed as the building block of all modern technology. It is these tiny devices that control the flow of electrons in all your electronics. In your computer alone, there are hundreds of millions of these transistors, all working together in a complex circuit. Previously, impr

This study has looked upon how a philosophy called Sumak Kawsay or Buen Vivir explains what health means. The studied philosophy has its origins in the Andes in Latin America. The reason why this study was done came from the writers wish to understand what the philosophy meant, and how it could be used within public health-work. The writer thought that it is important to include different explanat

Reducing train delays important in many countries, even in those like Japan, where punctuality is already high.

Quantum key distribution (QKD) is a secure encryption key generation process to be used by two users in the presence of an eavesdropper. The no-cloning theorem allows the sender "Alice" to securely send qubits with single photons to the receiver "Bob". However, due to real-life imperfections, it is not always possible to have a single-photon source with its properties matching Since the dawn of the first civilizations, the security of information has proven vital to the success of any given community. History records the first attempts at using cryptography techniques in a 1900 BC to 600 BC time frame. In ancient times, the working mechanism of this technique involved the use of letters in the alphabet. To secure the information, these techniques shifted the letters’ nu

Popular Abstract in English Human life in general, depends on having access to useable forms of energy for meeting the basic needs such as preparation of food and provision a comfortable place to live. Energy is also necessary for running the societal services for instance, transportation, health care and education. It is important to know what energy resources are available, how much energy is nEnergy is among the main driving forces needed for sustainable development. Provision of energy services, from the supply side to transmission/distribution and use, must include management, and good management requires tools. Energy planning is a tool for managing the community energy system through assessing and balancing supply and demand. This thesis explains an approach to energy planning whic

Group A Streptococcus (GAS) is a significant human pathogen that has developed multipleimmune evasion mechanisms to counter the host immune response. One of these mechanisms involvesthe production of the M protein, which, amongst other things, acts as an anti-phagocytic factor and canbind host proteins. Another is the ability of M protein to bind a human protein called fibronectin (Fn). Thisprotei
