Mutagenic/carcinogenic heterocyclic amines (HAs) are formed at low levels (ng/g) during heat processing of protein-rich food such as meat and fish. The complex matrix requires effective extraction and purification methods. Blue Chitin columns were used for the extraction of HAs from fried chicken fillets and the samples were analysed with LC-MS. Several HAs were identified at levels ranging from 0
In 1935 and 1936 there was a hard labour conflict in the market garden business in the city of Malmö and its environs. The Parties were Allmänna Arbetsgivareföreningen (the General Federation of Employers), an affiliation of Svenska Arbetsgivareföreningen (the Swedish Employers Federation), SAF, on the one hand and on the other Svenska Lantarbetareförbundet (the Swedish Union of Agricultural Worke
The effect of irradiation on S-phase duration (Ts), labelling index (LI), potential doubling time (Tpot), and cell cycle phase distributions was determined by DNA flow cytometry in xenografted human squamous cell carcinoma of the head and neck (SCCHN). Tumours were treated with a single dose of 3 Gy, and excised at intervals over a 90-h period. Six hours before each excision the tumours were label
The aims of the current study were to collect intestinal spirochaetes (genus Brachyspira) from farmed and wild mallards (Anas platyrhynchos) and to identify and classify those isolates that phenotypically resembled Brachyspira hyodysenteriae, an enteric pathogen of pigs. The isolation rate of Brachyspira spp. was high from both farmed (93%) and wild mallards (78%). In wild mallards, it appeared th
The manual describes the use of TrueTime, a Matlab/Simulink-based tool for simulation of distributed real-time control systems. The tool facilitates detailed co-simulation of plant dynamics, controller task execution, and network transmissions. The TrueTime Kernel and TrueTime Network blocks are described, and the real-time kernel primitives are detailed.

Inclusive differential cross sections dsigma(pA)/dx(F) and dsigma(pA)/dp(t)(2) for the production of K-S(0), Lambda, and (&ULambda;) over bar particles are measured at HERA in proton-induced reactions on C, Al, Ti, and W targets. The incident beam energy is 920 GeV, corresponding to roots = 41.6 GeV in the proton-nucleon system. The ratios of differential cross sections dsigma(pA)(K-S(0))/dsig

Female students' traditional and non-traditional choices of education is the subject of this study. Facing difficult choices on different levels of the educational system girls often, statistically, make traditional choices, but they also in different ways break traditional patterns. The study takes its starting-point in the following issues: What is the girls' understanding of the formal liberty
Mechanical properties of isolated smooth muscle strips from human urinary bladder were investigated in vitro. Bladder tissue was obtained from tumour-free wall regions of bladders from male patients undergoing cystectomy for bladder carcinoma. In intact muscle strips, activated with high-K+ solution, half-maximal force occurred at about 0.9 mM extracellular [Ca2+]. The length-active force relation
Travel patterns among different socio-economic groups in Sweden are investigated. It is shown that elderly persons, persons with low incomes and women in general do not travel extensively. Middle-aged persons, persons with high incomes and men travel much farther. Cars are the dominant transportation mode for all population groups. Aeroplanes are used mostly by high-income earners and men, while p
In this correspondence, unequal error-correcting capabilities of convolutional codes are studied. For errors in the information symbols and code symbols, the free input- and output-distances, respectively, serve as '' unequal '' counterparts to the free distance. When communication takes place close to or above the channel capacity the error bursts tend to be long and the free distance is not any
Popular Abstract in Swedish Som en blixt från klar himmel drabbas en ung, och till synes frisk person, av hjärnblödning. Denna stroke leder till demens och efterföljande nya blödningar leder slutligen till en för tidig död. Man har kunnat visa att denna sjukdom beror på att en variant av ett visst protein, cystatin C, tvinnar ihop sig till rep-liknande långa fibriller. Dessa fibriller ansamlas sedAmyloidosis is a group of diseases characterized by a change in protein conformation resulting in aggregation and tissue deposition of amyloid fibrils. One variant of cystatin C, L68Q cystatin C, is highly amyloidogenic and persons carrying the corresponding gene suffer from massive cerebral amyloidosis leading to brain hemorrhage and death. Amyloidogenic proteins like cystatin C and prion protein
A biosensor based on the surface plasmon resonance (SPR) principle was used for kinetic analysis of lectin interactions with different immobilized saccharide structures. A novel affinity ligands beta-D-glycopyranosylmethylamines derived from common D-aldohexoses linked to the carboxymethyl dextran layer of the SPR sensor surface served for interactions with a wide range of lectins. The method of p
The leaching process when water attacks concrete, and the effect of leaching on the strength and durability of a concrete structure, is analysed theoretically. Technique for prediction of the future leaching and structural stability is outlined. The analysis is to a certain extent supported by data from literature. The leaching process is divided in five different types: 1: Pure surface leaching 2
Study Design. Randomized efficacy trial comparing two types of noninstrumented posterolateral fusion between L5 and S1 in patients with L5 spondylolysis and vertebral slip less than 50%, as evaluated by radiosterometric analysis. Objective. To determine whether osteogenic protein-1 (BMP-7) in the OP-1 Implant yields better stabilizing bony fusion than autograft bone. Summary of Background Data. An
