The move 'outside' of the concert hall has repercussions for listening and creative practice beyond simply resituating 'music'. The building of an environmentally specific instrumentarium draws on in situ exploration and cultivation of affordances, but also on the embodied pre-existent knowledge of the artists concerned. A sense of space/place and strategies of listening work together both to situ
I will take a recent CD-project as point of departure, a collaboration with the Turkish composer and electronic musician Erdem Helvaciolu. We did a series of recording sessions in Istanbul in December 2009 for which we agreed to use the Turkish makam as common point of departure in all the pieces. In this paper I will discuss the resistance of this material and specifically the relation between th
This paper discusses the soundscape of Hanoi and of the countryside north of Hanoi in the Bac Ninh province with the experience of the two authors as artists in two collaborative projects, Arrival Cities: Hanoi and Que/Homelands. The content is structured in three layers, a conversation between the two authors on their individual experience of the projects, a jointly written text which takes a mor
With the MAX IV project in Lund, Sweden, an ultralow emittance storage ring light source is going into user operation in 2016. Due to its multibend achromat lattice designthe 3 GeV storage ring reaches a horizontal emittance lower than 330 pm rad. Emittance diagnostics will involve two diagnostic beamlines to image the electron beam with infrared and ultraviolet synchrotron radiation from bending
Falsterbo Peninsula on the south coast of Sweden is low-lying and exposed to flooding. In 1872 the extremestorm surge Backafloden caused large devastation on the Swedish, Danish, and German coasts in the SouthBaltic Sea. For the Falsterbo Peninsula, the peak storm surge level is estimated to have been 240 cm abovenormal. If a similar event happened today, the consequences would be far worse, as exFalsterbo Peninsula on the south coast of Sweden is low-lying and exposed to flooding.

Sweden is widely considered to have one of the most equal and gender-equal societies in the world. But the Swedish society is also one in which the Labour Court can find discrimination when a 60-year-old ‘Swedish’ ‘white’ woman fails to get a job interview – yet not when workers call a colleague of Gambian background ‘blackie’, ‘big black bastard’, ‘the African’, and ‘svartskalle’, or a man of Nig
Apolipoprotein A1 (apoA1) is the main protein component responsible for transportation of cholesterol on high-density lipoprotein (HDL). Serum amyloid A (SAA) is an acute phase protein associated with HDL. Apart from their physiological functions, both apoA1 and SAA have been identified as 'amyloidogenic peptides'. We report herein that the polysaccharide heparin interacts with both apoA1 and SAA
RATIONALE: Tandem mass (MS/MS) spectra generated by collision-induced dissociation (CID) typically lack redundant peptide sequence information in the form of e.g. b- and y-ion series due to frequent use of sequence-specific endopeptidases cleaving C- or N-terminal to Arg or Lys residues.METHODS: Here we introduce arginyl-tRNA protein transferase (ATE, EC 2.3.2.8) for proteomics. ATE recognizes aci
The Escherichia coli inner membrane protein CysZ mediates the sulfate uptake subsequently utilized for the synthesis of sulfur-containing compounds in cells. Here we report the purification and functional characterization of CysZ. Using Isothermal Titration Calorimetry, we have observed interactions between CysZ and its putative substrate sulfate. Additional sulfur-containing compounds from the cy
Gram-positive bacterium Streptococcus mutans is the primary causative agent of human dental caries. To better understand this pathogen at the atomic structure level and to establish potential drug and vaccine targets, we have carried out structural genomics research since 2005. To achieve the goal, we have developed various in-house automation systems including novel high-throughput crystallizatio
p90 ribosomal S6 kinases (RSKs) respond to various mitogen stimuli and comprise two distinct protein kinase domains. The C-terminal kinase domain (CTKD) receives signal from ERK1/2 and adopts an autoinhibitory mechanism. Here, the crystal structure of human RSK1 CTKD is reported at 2.7 Å resolution. The structure shows a standard kinase fold, with the catalytic residues in the ATP-binding cleft or
NMD3 is required for nuclear export of the 60S ribosomal subunit in yeast and vertebrate cells, but no corresponding function of NMD3 has been reported in plants. Here we report that Arabidopsis thaliana NMD3 (AtNMD3) showed a similar function in the nuclear export of the 60S ribosomal subunit. Interference with AtNMD3 function by overexpressing a truncated dominant negative form of the protein la
The 23S rRNA nucleotide m(2)G2445 is highly conserved in bacteria, and in Escherichia coli this modification is added by the enzyme YcbY. With lengths of around 700 amino acids, YcbY orthologs are the largest rRNA methyltransferases identified in Gram-negative bacteria, and they appear to be fusions from two separate proteins found in Gram-positives. The crystal structures described here show that
The RlmL (YcbY) protein in Escherichia coli is an rRNA methyltransferase that is specific for m(2)G2445 modification of 23S RNA. The rlmL gene was cloned into the expression vector pET28a and expressed in the host E. coli strain BL21 (DE3). Recombinant protein with a six-histidine tag was purified by Ni(2+)-affinity chromatography followed by gel filtration. Crystals were grown using the hanging-d
Tubulin-folding cofactor A (TFC A) is a molecular post-chaperonin that is involved in the beta-tubulin-folding pathway. It has been identified in many organisms including yeasts, humans and plants. In this work, Arabidopsis thaliana TFC A was expressed in Escherichia coli and purified to homogeneity. After thrombin cleavage, a well diffracting crystal was obtained by the sitting-drop vapour-diffus
Microtubules are composed of polymerized alpha/beta-tubulin heterodimers. Biogenesis of assembly-competent tubulin dimers is a complex multistep process that requires sequential actions of distinct molecular chaperones and cofactors. Tubulin folding cofactor A (TFCA), which captures beta-tubulin during the folding pathway, has been identified in many organisms. Here, we report the crystal structur
