DNA chemical and physical networks have been investigated with respect to their stability and swelling, and rheological properties. Chemical networks were prepared by cross-linking DNA with ethylene glycol diglycidyl ether (EGDE), and physical networks by association with cationic polymers. Both types of gels display strong elastic properties and have a shear thinning behaviour. Addition of cation

In recent years the use of BIM (Building Information Modeling) in the construction industry has increased dramatically. In the current situation, many of the major players use BIM both in the design and production phase. What remains is to explore is how BIM can be used in property management. Purpose: The purpose of this study is to find out which information the contractor must put in the BIM mo

BACKGROUND: Drug-coated devices are frequently used in coronary and peripheral interventions, but their effect on amputation risk in peripheral artery disease is unclear. We assessed whether drug-coated devices affect the rate of above-ankle amputation in patients with chronic limb-threatening ischaemia undergoing infrainguinal endovascular revascularisation.METHODS: The Swedish Drug-Elution Trial

Möjlig lösning av bristen på bloddonationer med hjälp av outforskat havrehemoglobin. Hemoglobin är främst förknippat med blod i oss människor och andra djur, men tänk om någon berättade att det syretransporterade proteinet också finns i växter. Underligt, eller hur? Växter har ju inget blod men ändå finns det där. I denna rapport beskrivs identifieringen av tre nyfunna havrehemoglobin som har likHemoglobin is mainly viewed as an oxygen and carbon dioxide carrier in the blood of animals and thus essential for life as we know it. During the course of evolution, plants have also developed versions of this protein, for similar and different purposes, such as regulation of nitric oxide levels. A lot of research has been put into characterization of hemoglobin from monocots, including rice, bar

Brottslighet och särskilt organiserad brottslighet, utgör ett problem för samhället i Sverige men också i andra länder. I statsmaktens arbete mot kriminalitet är hindrande av möjligheterna till penningtvätt, ett viktigt inslag. Penningtvättsåtgärder kan nämligen allmänt beskrivas syfta till att dölja eller omsätta vinning av brottslig verksamhet. Studier har visat att omfattande summor pengar frånCrime and in particular organized crime, is a problem for the society in Sweden but also in other countries. Obstruction of opportunities for money laundering is an important element to the authorities in their struggle against crime. Money laundering can generally be described as seeking to conceal or convert the proceeds of criminal activity. Studies have shown that substantial amounts of money

Ubiquitination is a post-translational modification process that has a very important role in the homeostasis of eukaryotic cells. Linkage-specific ubiquitination determines the final destination of modified protein. Ubiquitination has also been reported to regulate inflammasome function and IL-1β degradation. Secretion of IL-1β by macrophages in response to inflammasome activation is a key proces

Vi lever idag i ett digitalt samhälle. Du använder förmodligen själv dagligen olika program och även om all mjukvara i slutändan består av ettor och nollor finns det allt som oftast en person bakom varje program som tagit fram den, en utvecklare. Programmerare tar ofta hjälp från så kallade mjukvaruplattformar. Dessa riktar sig inte direkt mot vanliga användare, utan mot just utvecklare av mjukvaThis research report was carried out in collaboration with Qlik AB and aimed to identify what aspects are needed from a software platform in order for developers to want to use them. It also aimed to identify how well the software platform Qlik Core had implemented these aspects. The research used online questionnaires, interviews and data analysis using Qlik Sense. The research compared how diffe

As neural networks find more and more practical applications targeted for edge devices, the implementation of energy-efficient architectures is becoming very crucial. Despite the advancements in process technology, power and performance of memories remain to be a bottleneck for most computing platforms. The aim of this thesis is to study the effect of the breakdown structure of memories on power c

Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. However, wheat bran could be used in biorefineries for production of value-added products such as bioplastics, biofuels and chemicals as a substitute for fossil feedstocks as petroleum. Since wheat bran is an agri

As a reaction to our current fast living and increasingly individualistic society, the focus on presence and need for human interaction is rising. With inspiration from Marina Abramovic’s performance work “The artist is present” at MoMa in New York, this project has been focusing on how to create a setting which enhances the interaction between two people. During this project, the aspect of inter

Pallets are the most common tertiary packaging solution with over 80% the world trade currently being carried out using pallets. The most widely used pallet type is the four-way wood pallet which accounts for 86% of the pallet production worldwide and the most common pallet size is the Euro Pallet. A department at Tetra Pak called Additional Materials (AddMat) is mainly using Euro Pallets, which h

Bröstcancer är den vanligaste cancerdiagnosen för kvinnor och årligen drabbas över 9000 i Sverige. För att hitta cancern i ett tidigt stadium genomförs regelbunden screening (massundersökning) med mammografi (bröströntgen) för kvinnor i åldern 40–74. Artificiell intelligens (AI) och mekanisk avbildning, Mechanical Imaging (MI), har använts i separata studier inom mammografi för att underlätta granArtificial intelligence (AI) and mechanical imaging (MI) have been used in separate studies in breast imaging. They have individually shown great possibilities within the field of mammography, but the use of the two techniques together have never been evaluated. The artificial intelligence application used in this work was Transpara, a deep learning convolutional neural network. It distinguishes p

Tupí-guaraníspråken omagua [omg] och kokama [cod] utgör intressanta exempel på omfattande språkkontakt i Amazonas. Detta framgår av språkens lexikon, som till största delen består av ord från tupí-guaraníspråk, men med en hög andel ord från obesläktade språk. Det framgår också av grammatiken, som skiljer sig mycket från andra tupí-guaraníspråk. Det språk som var huvudsaklig lexifierare i kontaktsiThe Tupí–Guaraní languages Omagua [omg] and Kokama [cod] constitute interesting examples of heavy language contact in Amazonia. This is evident from their lexicon, which is mostly Tupí–Guaraní, but with a high percentage of non-Tupí–Guaraní forms, and the grammar, which is very distinct from other Tupí–Guaraní languages. The lexifying Tupí–Guaraní language in this contact situation is believed to
