Novelty detection of foreign objects in food using multi-modal X-ray imaging

In this paper we demonstrate a method for novelty detection of foreign objects in food products using grating-based multimodal X-ray imaging. With this imaging technique three modalities are available with pixel correspondence, enhancing organic materials such as wood chips, insects and soft plastics not detectable by conventional X-ray absorption radiography. We conduct experiments, where several

Effects of signal peptide mutations on processing of Bacillus stearothermophilus α-amylase in Escherichia coli

Bacillus stearothermophilus α-amylase has a signal peptide typical for proteins exported by Gram-positive bacteria. There is only one signal peptidase processing site when the protein is exported from the original host, but when it is exported by Escherichia coli, two alternative sites are utilized. Site-directed mutagenesis was used to study the processing in E. coli. Processing sites for 13 B. s

Binding of a new Ca2+ sensitizer, levosimendan, to recombinant human cardiac troponin C : A molecular modelling, fluorescence probe, and proton nuclear magnetic resonance study

The binding of a new calcium sensitizer, levosimendan, to human cardiac troponin C (cTnC) is described. Fluorescence studies done on dansylated recombinant human cTnC and a site-directed mutant showed that levosimendan modulated the calcium-induced conformational change in cTnC, and revealed the role of Asp-88 in the binding of the drug to the NH2-terminal domain of cTnC. Furthermore, NMR studies

Mergers of semi-autonomous central agencies: The Swedish trajectory and the case of the Swedish Social Insurance Agency

As the number of autonomous executive agencies increases, some countries have started merging agencies, thereby aiming to reduce fragmentation and cut public spending. These mergers have passed conspicuously unnoticed in research. In Sweden, the current wave of agency mergers started in the 1990ies. This paper aims to (1) give a background to the Swedish trajectory with agency mergers and to (2),

The Theology of Land in Jewish-Christian Relations and Its Role in Misunderstandings between Jews and Christians

Without sufficient knowledge of the painful history of Jewish-Christian apologetics and polemics, commencing already in late antiquity and continuing to medieval times, one easily fails to recognize the complexities of current Christian approaches to the Land, now known as Israel and/or Palestine. The purpose of this chapter is to examine the interplay of theology and politics, and especially to r

Tendenser inom varumärkesrätten: studier i immaterialrätt

Boken fångar in den nya utveckling som varumärkesrätten genomgår till följd av förslag om ny lagstiftning, men också till följd av den explosiva utveckling som sker på EG-planet. Den som för några år sedan uppfattade varumärket som en begränsad monopolrätt för att ange varors ursprung måste nu acceptera att helt nya vindar blåser, som medför att det mesta går att registrera och att skyddet förstär
