To avoid SNR degradation due to jitter, sampling time errors must be less than 90fs rms. This accuracy is achieved through a combination of a low noise clock path and a 2-rank T/H architecture, as shown in Fig. 26.3.1. Clocked at the full 2.5GHz sampling rate via a low-jitter CMOS driver chain, the first T/H stage sets the sampling instant. Eight(More)
Using the monofrequency oscillation technique, the oscillatory measured resistance of the respiratory system (Ros) was determined in healthy and pneumonic calves younger than 2 months. Using a face mask, measurements were done in unsedated animals directly in the calfhouse. 106 clinically healthy calves were examined to determine the physiological range of(More)
LPS antibody reaction of S. Typhimurium was detected in a total of 111 two- to ten-week-old pigs, which had been exposed to experimental oral infection with this serovar in 16 separate experiments. The total antibody level was determined according to the meat juice ELISA provided for the Salmonella control programme and the antibody concentrations of the(More)
Transcutaneous PO2-measurement has been thought being non practicable in veterinary medicine. Consequently, the measuring method has been slightly modified. PO2 was taken from the mucous membrane of the lower surface of tongue. This has been practised in 6 dogs and 10 calves. We achieved a significant correlation between transmucosal and arterial PO2, taken(More)
The development of the antibody concentration against lipopolysaccharide (LPS) of S. Typhimurium und S. Choleraesuis in rearing pigs during the fattening period and in breeding sows of the corresponding age was recorded. The studies revealed the following results. Antibodies of isotypes IgG1 and IgG2 revealed a more pronounced specificity against the(More)
Using the close linear regression between the logarithm of the dilution degree of a sample and the logarithm of the extinction measured in an ELISA both the relative concentrations of immunoglobulines of the isotypes IgG, IgM and IgA and of the LPS antibodies against S. Typhimurium of the different isotypes in blood sera and meat juice of 15 slaughtered(More)
UNLABELLED The impulse oscillometry system (IOS) which was originally developed for human medicine was found to be suitable for analysing respiratory mechanics in spontaneously breathing animals. This technique is non-invasive. METHODOLOGICAL ASPECTS In order to use the IOS-technique in animals, a tightly fitting face mask is necessary. Furthermore, a(More)
In the in vitro model using Caco-2 cells at different stages of differentiation the invasion and intracellular survival of virulent (predominant infection strains) and less virulent (predominant attenuated mutant strains) Salmonella strains were studied. The statistical evaluation of experimental data has shown that the logarithmized colony forming unit(More)
