Vad kännetecknar en text av god kvalitet och hur starkt påverkar textens utformning, sammansättning och uppbyggnad ifall en avhandling eller rapport uppfattas som högkvalitativ? Dessa frågor har aktualiserats med anledning av Högskoleverkets utvärderingssystem av utbildningar, som lägger stor vikt vid skriftliga rapporter producerade i samband med examensarbeten. Detta nummer av Lärande i LTH h...

It is well known that dietary fibre is good for the health. Cereals, and in particular the outer parts of the cereal kernels, are rich in dietary fibre. Rye bran, wheat bran, oat bran and barley fibre have been investigated regarding their suitability as additives in low-fat meat products. Two types of meat products, frankfurter-type sausages and meatballs have been evaluated in this thesis. In...

The field of organic electronics emerged in the 1970s with the discovery of conducting polymers. With the introduction of plastics as conductors and semiconductors came many new possibilities both in production and function of electronic devices. Polymers can often be processed from solution and their softness provides both the possibility of working on flexible substrates, and various advantag...

This report investigates pulse-synchronised amplitude modulation as a method for perceptual fusion of noise and tone. It is shown that when the noise is amplitude modulated by the waveform envelope of the tone, higher amplitude modulation depth yields stronger fusion. In addition, the evidence suggests that fusion remains constant for tone frequencies from 150 to at least 600 Hz. Sammanfattning...

How can we re-empower opera singers, extending their control over accompaniment and vocal expressivity? To answer this question, I have opened a novel design space, Extending Opera, consisting of interactive artist–operated tools to be used on-stage. The research has its methodological groundings in Research through Design (RtD) and Research through the Arts (RttA). This particular method is co...

Modeling and simulation of complex systems is at the heart of any modern engineering activity. Engineers strive to predict the behavior of the system under development in order to get answers to particular questions long before physical prototypes or the actual system are built and can be tested in real life. An important question is whether a particular system design fulfills or violates requi...

När en cell utsätts för strålning startar en signalkaskad som kan aktivera DNA-reparation, hämma celldelning och påverka cellens benägenhet att dö. En sådan signalväg är HER2/fosfatidylinositol 3-kinas (PI3K)/AKT, som bland annat reglerar celltillväxt, celldelning och en form av celldöd som kallas apoptos. HER2 är uttryckt i onormalt höga nivåer i 1530% av alla brösttumörer och är relaterat til...

This work shares purpose with new directions in the philosophy of intellectual property, where selfexpression and participation in the creation of culture are seen as key ingredients of human wellbeing and autonomy. A technical solution is explored that enables major labels and independent creators to publish music with equal reach to audiences, without the need for trusted third parties. The p...

We investigated the cytotoxicity of eight vitamin K3 (VK3) analogs against neuroblastoma cell lines (IMR-32, LA-N-1, NB-39, and SK-N-SH) and normal cell lines (human umbilical vein endothelial cells (HUVEC) and human dermal fibroblasts (HDF)) using a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. 2-[(2-Methoxy)ethylthio]-3-methyl-1,4-naphthoquinone (VK3-OCH(3)) showed...

This paper proposes a new generation Computer Enhanced Systems Engineering (CESE) tool known as an Operations Concept Harbinger (OCH). The OCH is the result of the application of information management technology to solving the problem of poorly implemented requirements engineering, in particular poorly written and articulated requirements as well as the effect of changing requirements for both...
