solution heat treatment, the aluminum alloy is heated to a temperature range between 400 and 540 °C in order to re-dissolve the soluble alloying elements in solution to produce a single phase solution, that is, a solute-rich solid solution after holding at
One of the most complex cases for assessing the nuclear power plant safety is the evaluation of the response of the plant to an earthquake and calculation of the core damage frequency related with this. Plant level fragilities are convolved with the seismic hazard curves to obtain a set of doublets for the plant damage state. The standard methodology of the description of randomness and epistemic uncertainty of the fragility is based on the use of lognormal distribution. In the practice, because of large number and variety of types of components, variety of failure modes, further simplification is needed in spite of simplicity of the mathematic description of the fragility and its uncertainty. Sophisticated modeling and screening methods have to be applied for plant fragility development requiring enormous experience. Several practical assumptions utilized in the seismic PSA showing certain analogy with interval type description of uncertainties. In the paper an attempt is made for outlining some new options for nuclear power plant seismic fragility development based on the interval and p-box concept. The possibility for derivation of conditional probability of failure for cumulative absolute velocity is also highlighted.

. Fundamentals settings associated with the FEM are first to be fixed by examining the model convergence in terms of the grid independence test, near wall treatment and the location of the border of the discretized finite domain of calculation. This paper
The structure of public water supply in Germany and the water resources used are briefly described. An overview over the legal requirements for drinking water is given, and the sources for contaminants are outlined. Then the multiple-barrier approach is discussed with respect to the resources groundwater and spring water, lake and reservoir water, and river water. Examples for treatment schemes are given and the principle of subsurface transport of river water as a first treatment step is described.

Shell eggs have been irradiated with increasing radiation doses in the 0.5-3.0 kGy dose range and various non-microbiological changes, important from the point of view of consumer quality, have been estimated. Dose-dependent changes in the flow behaviour of egg white and brittleness of the yolk membrane in broken eggs, sensorial parameters of the raw and soft-boiled eggs, whippability and foam stability of the egg white were observed. Considering that a minimal dose of 1.5 kGy would be required for radiation inactivation of salmonellae and other, non-pathogenic bacteria, the quality of irradiated eggs upon such gamma radiation dose would not be equal in all parameters to those of the fresh shell eggs, however, changes in sensorial and functional properties at this dose level may be still acceptable, mainly for risk population and some industrial use.

There are numerous biological agents including bacteria such as Brucella suis, B. abortus, Francisella tularensis, Burkholderia mallei, Coxiella burnetii, Yersina pestis, Bacillus anthracis and Chlamydia psittaci, viruses such as Variola major and V. minor, Flavivirus and Hantavirus, and toxins such as Botulinum toxin produced by the bacterium Clostridium botulinum, Staphylococcus enterotoxin B and Trichothecene mycotoxin reported to have potential to cause illness via water consumption. In the recent years, biological threat prevention for urban water supply systems has been of special interest worldwide, thus, protection against biological agents requires adequate knowledge, available water treatment technologies and preparedness. In this review, the history of biological threat via public water supply, as well as selected early detection methods, prevention strategies and risk assessment models are detailed.
