A new approach to capillary electrochromatography: Disposable molecularly imprinted nanoparticles
Nanoparticle phases have provided a new technique for CEC that avoids the time-consuming procedure for packing capillary columns. Frits are not required in the separation channel, and because the pseudo-stationary phase is discarded after every separation, each run proceeds with an entirely new phase. Moreover, the monolithic molecularly imprinted polymer permits a high sample load to be used.

Priorities in optimisation of medical X-ray imaging - A contribution to the debate
A simplistic approach to optimising medical imaging is to use the lowest effective dose to the patient that does not jeopardise a correct diagnosis. With limited resources and over 1000 different types of X-ray examinations, it is not always easy to set the right priorities and to decide how to perform the optimisation. Recent research shows that the 'Rose model' for the detection of specific stru

Master of Science in Risk Management and Safety Engineering at Lund University, Sweden - Executive Summaries
To obtain a Master of Science in Risk Management and Safety Engineering at Lund University the students must write a master’s thesis based on a final project. The efforts correspond to full-time studies for one semester, i.e. 30 ETCS credits or 20 Swedish credits. The students can choose to write the report in Swedish, i.e. their mother tongue, or in English. In addition to the thesis a student is
Cross section measurements of charged pion photoproduction in hydrogen and deuterium from 1.1 to 5.5 GeV
The differential cross sections for the gamma n ->pi(-)p and the gamma p ->pi(+)n processes were measured at Jefferson Lab. The photon energies ranged from 1.1 to 5.5 GeV, corresponding to center-of-mass energies from 1.7 to 3.4 GeV. The pion center-of-mass angles varied from 50(degrees) to 110(degrees). The pi(-) and pi(+) photoproduction data both exhibit a global scaling behavior at high energi

Neisseria meningitidis undergoes PilC phase variation and PilE sequence variation during invasive disease
Neisseria meningitidis colonizes the upper respiratory tract (URT), enters the blood stream, and reaches the cerebrospinal fluid (CSF). In the present study, we show that bacteria isolated from the URT adhere better to human epithelial cells, compared with bacteria from blood or CSF, which suggests that important changes of virulence-associated proteins take place during bacterial dissemination. P
COPD exacerbations: the importance of a standard definition
Efforts to assess the efficacy of new therapies in the treatment of acute exacerbations of chronic obstructive pulmonary disease (COPD) have been hampered by the lack of a widely agreed and consistently used definition. A variety of definitions have been used in clinical studies, based on changes in patient symptoms or the requirement for antibiotic therapy, oral steroids or hospitalisation. To da
Boris Lurie and NO!art
Article about the Latvian-American artist Boris Lurie, the art movement NO!art, founded by Lurie, Sam Goodman and Stanley Fischer in 1959 in New York, and the reception history of Lurie and NO!art from the 1960s until today. Accompanied by an extensive interview with Boris Lurie.

Formation of amyloid-like fibrils upon limited proteolysis of bovine alpha-lactalbumin
Bovine alpha-lactalbumin (alpha-LA) (10 g L-1) was incubated with a protease from Bacillus licheniformis at pH 7.5 and 50 degreesC. The reaction was biphasic consisting of an initial hydrolysis of intact alpha-LA and formation of dimers from large hydrolysis products within 60 min followed by aggregation of dimers into aggregates of 500 kDa. The aggregates consisted primarily of fibrillar strands
Measuring moisture gradients in cellulose fibre networks: An application of the magnetic resonance imaging method
A magnetic resonance imaging method was employed to measure moisture distributions in pulp samples. A calibration experiment shows that, in the range of moisture contents up to 1.4 g water/g dry substance, the MRI signal is linearly proportional to the mass of moisture of the pulp sample. The in-situ drying of a pulp sheet approximately 4 mm thick was them studied. The resolution in the thickness

Measurement of anti-deuteron photoproduction and a search for heavy stable charged particles at HERA
The cross section for anti-deuteron photoproduction is measured at HERA at a mean centre-of-mass energy of W-gammap=200 GeV in the range 0.2 < p(T)/M < 0.7 and y < 0.4, where M, p(T) and y are the mass, transverse momentum and rapidity of the anti-deuteron in the HERA laboratory frame, respectively. The numbers of anti-deuterons per event are found to be similar in photoproduction to those in cent
Atomic and electronic structure of the Yb/Ge(111)-(3x2) surface studied by high-resolution photoelectron spectroscopy
Using high-resolution synchrotron-radiation photoelectron spectroscopy and low-energy electron diffraction, we have studied the electronic and structural properties of the Yb-induced Ge(111)-(3x2) reconstruction with a 1/6 monolayer coverage. We found these properties to be similar in many respects to those of the metal-induced Si(111) and Ge(111) reconstructions described previously in terms of t
Fusion of RDC1 with HMGA2 in lipomas as the result of chromosome aberrations involving 2q35-37 and 12q13-15.
Rearrangements of chromosome bands 12q13-15 are frequent in various benign mesenchymal and epithelial tumors, and the gene HMGA2 seems to be the most common target within this chromosome region. In the majority of cases, the rearrangements result in a fusion of the first three exons of HMGA2 with different translocation partners. Despite the large number of HMGA2 mutations that have been reported,
Siberian wetlands: Where a sink is a source
[1] A greenhouse gas inventory can for some ecosystems be based solely on the net CO2 exchange with the atmosphere and the export of dissolved organic carbon. In contrast, the global warming effect may be more complex in ecosystems where other greenhouse gases such as CH4 or N2O have significant exchanges with the atmosphere.
