We studied the response of methane production and oxidation potentials in a minerotrophic and an ombrotrophic mire to water table ̄uctuations. In pro®les where water table had not varied, the water-saturated layers showed signi®cant potentials while the unsaturated layers did not. The production potentials in the saturated layers below water level ranged(More)
The objective of this study was to estimate and compare variance components and sire breeding values for disease resistance to vibriosis in Atlantic cod (Gadus morhua L.) using 3 statistical approaches. A total of 3,576 individually tagged juvenile cod from 50 full-sib families were infected with Vibrio anguillarum, which causes vibriosis, a frequently(More)
Chicken avidin and bacterial streptavidin are proteins used in a wide variety of applications in the life sciences due to their strong affinity for biotin. A new and promising use for them is in medical pretargeting cancer treatments. However, their pharmacokinetics and immunological properties are not always optimal, thereby limiting their use in these(More)

A preconditioned conjugate gradient method was implemented into an iteration on a program for data estimation of breeding values, and its convergence characteristics were studied. An algorithm was used as a reference in which one fixed effect was solved by Gauss-Seidel method, and other effects were solved by a second-order Jacobi method. Implementation of(More)
The characterization of respiratory air flow patterns is a subject of continuous interest. The pattern of the air flow curve is an individual characteristic which remains constant over long periods of time. Basically two different approaches have been proposed to determine the individual parameters of the respiratory flow, namely the graphical(More)
Recent studies have shown that intelligent systems approaches have potential for solving complex industrial problems. In addition, process data is valuable for the process state monitoring and knowledge management of the process and it can be used for the optimization of productivity. In this paper novel approach for dynamic process state monitoring is(More)
