Säker hantering av animaliska biprodukter minskar spridning av sjukdomar Ungefär 200 människor har dött på grund av Creutzfeldt-Jakobs sjukdom, efter att ha ätit kött från sjuka kor. Sjukdomen är förknippad med den ”galna ko-sjukan” även kallat Bovin Spongiform Encefalopat (BSE). BSE sprider sig genom att kött- och benmjöl framställt av BSE-sjuka nötkreatur har använts som foder. BSE sprids till Animal by-products (ABP) is an unknown area in food control in Sweden, mainly grocery stores. ABP affects many different areas, such as food, feed, animal welfare and waste. Swedish Board of Agriculture defines animal by-products as follows: "Animal by-products are material from the animal kingdom which is not food and have not yet been processed or treated to be included in the concept of m

Korslimmat trä, KL-trä, är ett förhållandevis nytt byggnadsmaterial i byggbranschen. Det består av ett udda antal skikt av lameller av konstruktionsvirke, där varje skikt av lameller ligger roterade 90 grader i förhållande till intilliggande skikt. Materialet används både i den bärande stommen och som stomkomplettering i form av exempelvis trappor. Idag finns endast en etablerad tillverkare på dCross-laminated timber, CLT, is a rather new building material. It consists of an odd number of layers consisting of lumber boards stacked together, where each layer is rotated 90 degrees in comparison to the adjacent layers. The material is used both as a load-carrying element as well as a non-load-carrying element, such as stairs. Today there is only one established producer of CLT in Sweden. D

Nevertheless, research indicates that only few of the sus

Background: In todayʼs fast moving world, the communication of science and technology is playing an increasingly important role for the relation between science and the public. Both journalists and researchers have their own agenda when communicating as public interest, corporate science and the competition for funding increases. At the same time, the conditions on which stories about science can

Planet earth is getting hotter and regional climates are becoming increasingly unpredictable across the globe. Cities and communities on all continents are already impacted by the changing climate, but also by two other crises – the fossil-energy decent and the 6th mass extinction event. These three complex and interconnected crises all increase the risk of food becoming a scarce resource. In fact

Plastic has been a revolutionary material in human history. Plastic materials have several desirable properties, such as durability, low production costs, and versatility. This helps explain the increase in their use and production over the past 100 years. Plastics are synthetic polymers, with long repeating chains of monomers; this creates structures that are chemically stable and durable. The ov

Room acoustic simulations are an important tool, both for design of spaces with satisfactory acoustics and for use in virtual reality experiences. Auralization of acoustic simulations are becoming more and more important in the context of Virtual and Augmented reality (VR and AR respectively), as the technology is used more and more in healthcare, culture and research. In this work, ray tracing si

Popular Abstract in Swedish Många fåglar flyttar regelbundet långa sträckor mellan sina häckningsplatser och vinterkvarter. På rastningsplatser längs flyttningsvägen stannar fåglarna upp och äter, för att lagra upp de energi-lager de behöver som bränsle när de flyger. Vissa flyttfåglar lägger på sig så mycket bränsle (energi), mestadels som fett, att de dubblar sin kroppsvikt. Det lagrade bränsletBirds on migration alternate between consuming fuel stores during flights and accumulating fuel stores during stopovers. This thesis highlights some of the ways in which migrating birds have adapted to the different demands of fuelling and flight. Most of the time on migration is spent at stopover sites accumulating fuel stores. To minimise the total time spent on migration, birds should fuel up a

The demand for fast and energy efficient (opto-)electronic applications needs high mobility semiconductor materials, such as InAs with a very high electron mobility and GaSb with a very high hole mobility. Beyond the material itself, also an innovative device geometry is needed, for example, the gate-all-around geometry that provides higher efficiency and electrostatic control for computational un

While tau pathology is closely associated with neurodegeneration in Alzheimer's disease (AD), our prior work using multi-modality imaging revealed that mismatch between tau (T) and neurodegeneration (N) may reflect contributions from non-AD processes. The medial temporal lobe (MTL), an early site of AD pathology, is also a common target of co-pathologies such as limbic-predominant age-related TDP-

The sialyl Lewis x (SLex) tetrasaccharide is the smallest recognizable ligand for selectins. The selectins constitute a vital part of the inflammatory cascade for recruitment of leukocytes to a site of tissue damage or microbial infection. If too many leukocytes are recruited, normal, not injured, cells can be damaged; a process known from chronic inflammatory diseases such as reumatoid arthritis,

This paper describes a low distortion wide band CMOS direct digital RF amplitude modulator, which uses a 10-bit linear interpolation current steering digital to analog converter (DAC) and a Gilbert cell based mixer to generate an amplitude modulated RF signal directly. The linear interpolation increases the attenuation of the DAC's image components. The low pass filter (LPF) is therefore eliminate

Selective catalytic reduction of NOx (SCR) has been recognised as an effective post-combustion method for reducing nitrogen oxides from stationary sources. The cost of replacing the catalyst is a major part of the maintenance of the SCR system, hence it is desirable to advance methods to prolong the catalyst life. The objectives of this thesis were to investigate the extent and the mechanism of de

The design of efficient data structures is of primary importance in creation of theoretical algorithms as well their more tangible descendants, computer programs. In this dissertation we study computational aspects of data structures and their respective algorithms from a theoretical viewpoint, which are however of direct importance in the implementation of solutions for real-world problems. We pr

Popular Abstract in Swedish Inom området diagnostisk nuklearmedicin används radioaktiva läkemedel som ges (administreras) till patienterna i syfte att diagnostisera ett antal olika sjukdomstillstånd. Då man tar fram nya radioaktiva läkemedel för användning inom diagnostisk nuklearmedicin handlar det många gånger om att uppskatta mängden av ett visst upptag av radiofarmakat i olika organ och vävnadAn essential part of the development of new radiopharmaceuticals for use in diagnostic nuclear medicine is the determination of its biokinetic properties. The uptake and turn-over of the radiopharmaceutical in the source organs is of great interest since this could determine whether the radiopharmaceutical would be suitable for clinical use or not. It is also important that the biokinetics and dos
