In the development of new food products, more knowledge is needed about the occurrence and quantity of food-borne pathogens in the food chain to be able to implement effective control measures and assure food safety. In addition, improved understanding of how environmental factors and food preservatives effect the microbial virulence expression in foods will enable the formulation of new strategie
A method for determining the placement of x-ray absorption data into an experimental density of states for an adsorbate-semiconductor system is motivated and illustrated with the cases of bi-isonicotinic acid, isonicotinic acid, and benzoic acid on rutile TiO2(110). Special attention is paid to experimental aspects, as well as the role of Z+1 effects and the choice of reference level.
Purpose. To provide an overview of clinical research on the use of biochemical serum markers for traumatic brain injury (TRI) in the evaluation of patients with mild head injuries (MHI). Methods. The MEDLINE database was searched for publications on biochemical serum markers of TBI until August 2002. Clinical studies addressing their use in MHI were reviewed. Results. Desirable characteristics for
Background Several models for prediction of acute coronary syndrome (ACS) among chest pain patients in the emergency department (ED) have been presented, but many models predict only the likelihood of acute myocardial infarction, or include a large number of variables, which make them less than optimal for implementation at a busy ED. We report here a simple statistical model for ACS prediction th
We describe the detectors for identification of charged particles and fragments in CHICSi, a large solid angle multitelescope system mounted inside an ultra-high vacuum (UHV), cluster-jet target chamber. CHICSi performs nuclear reaction experiments at storage rings. The telescopes consist of a first very thin, 10-14 mum Si detector, a second 300 mum (or possibly 500 pm) ion implanted Si detector s
Results are reported for biosensors based on two different preparations of the same enzyme, laccase from Cerrena unicolor, one lyophilized and one stored frozen at - 18degreesC, for monitoring phenolic compounds. The enzyme was adsorbed on graphite electrodes and these were used in a flow through wall jet cell connected to a flow injection set-up. The electrodes were used at - 50 mV vs. AgAgCl. Th
A cultivation strategy combining the advantages of temperature-limited fed-batch and probing feeding control is presented. The technique was evaluated in fed-batch cultivations with E. coli BL21(DE3) producing xylanase in a 3 liter bioreactor. A 20% increase in cell mass was achieved and the usual decrease in specific enzyme activity normally observed during the late production phase was diminishe
Small-angle two-particle correlation functions, involving neutrons and protons, have been measured for E/A = 61 MeV Ar + Sn-112,Sn-124 collisions, i.e. systems similar in size but with different isospin asymmetry. The correlation strength of neutron-proton (np) and proton-proton (pp) pairs is stronger for the more neutron-rich system, indicating a shorter average emission time for this system. Com
The thesis deals with determination of the post peak behaviour of wood in pure tension and pure shear. Furhermore, the "Fictitious Crack Model" (FCM), which is a nonlinear fracture mechanics model ; originally developed for description of crack propagation in concrete, is employed to demonstrate the advantages of non linear fracture mechanics. A testing arrangement is presented with which the comp
The location of the red edge of the ZZ Ceti instability strip is definedobservationally as being the lowest temperature for which a white dwarfwith a H-rich atmosphere (DA) is known to exhibit periodic brightnessvariations. Whether this cut-off in flux variations is actually due to acessation of pulsation or merely due to the attenuation of anyvariations by the convection zone, rendering them invi
Background Open abdomen (OA) treatment often results in difficulties in closing the abdomen. Highest closure rates are seen with the vacuum-assisted wound closure (VAWC) technique. However, we have experienced occasional failures with this technique in cases with severe visceral swelling needing longer treatment periods with open abdomen. Feasibility and short-term outcome of a novel combination o
Extraction systems for hydrophobically tagged proteins have been developed based on phase separation in aqueous solutions of non-ionic detergents and polymers. The systems have earlier only been applied for separation of membrane proteins. Here, we examine the partitioning and purification of the amphiphilic fusion protein endoglucanase I(core)-hydrophobin I (EGI(core)-HFBI) from culture filtrate
SiGe Esaki diodes have been realized by rapid thermal diffusion of phosphorous into an SiGe layer grown by ultra-high-vacuum chemical-vapor-deposition on an Si p(+)-substrate for the first time. The phosphorous-doped SiGe forms the n(+)-electrode, while heavily boron-doped Si0.74Ge0.26 and Si substrate is used for the p(+) electrode. The diodes show a peak current density of 0.18 kA/cm(2), a curre
In the Swedish Knee Arthroplasty Study, all 699 Oxford meniscal bearing cemented unicompartmental prostheses (Biomet, Bridgend, UK) were identified and analyzed regarding failure pattern and compared with all Marmor prostheses (Smith & Nephew Richards, Orthez, France) and with a time-, age-, and sex-matched subset of Marmor prostheses using survival statistics expressed as cumulative revision
A computerised test termed the Stroop Strategy Test, utilising the Stroop effect, is described. To assess the test's usefulness and discriminant power, it was given to three military groups adjudged on the basis of interview and a test of intelligence to differ in their qualifications (61 men of Level 1, 41 of Level 2, and 17 of Level 3, in descending order) and a group of 16 men imprisoned or put
We describe a statistical measure, Mass Distance Fingerprint, for automatic de novo detection of predominant peptide mass distances, i.e., putative protein modifications. The method's focus is to globally detect mass differences, not to assign peptide sequences or modifications to individual spectra. The Mass Distance Fingerprint is calculated from high accuracy measured peptide masses. For the da
