A network design problem is to select a subset of links in a transport network that satisfy passengers or cargo transportation demands while minimizing the overall costs of the transportation. We propose a mathematical model of the foraging behaviour of slime mould P. polycephalum to solve the network design problem and construct optimal transport networks. In our algorithm, a traffic flow betw...
In moulding of large-size castings, the lack of uniformity in heating results in the deformation of individual mould parts. The resulting deformations cause internal stre-sses in the casting and scabbing in the mould. The main cause of deformation in the mould element is to be found in the α β transformation of the quartz grains. The allotropic modification of the quartz crystals from α into β ...
The magnitude of hearing loss in Pakistan is enormous. One in twelve children of Pakistan suffers from some form of hearing impairment. Many of them are unable to afford surgical procedures and resort to the use of cheap hearing aids fitted by untrained individuals or people lacking the required expertise. This predisposes the patients to significant complications during a process that is other...
Steel-making and continuous/mould casting are the key processes of modern iron and steel enterprises. The continuous and mould casting schedule of mixed whole/half charging plan is the bottleneck for the steel-making and continuous/mould casting process. However, it is very difficult to find a solution against the characteristics and complicated environment. This paper proposed a heuristic batc...
Pipek P., Rohlík B.-A., Lojková A., Staruch L. (2010): Suppression of mould growth on dry sausages. Czech J. Food Sci., 28: 258–263. The effects of two antifungal agents (natamycin, potassium sorbate) were compared on the mould growth on the surface of dry sausages (both heat treated and fermented). The mould growth was studied on fermented sausage Prešporska saláma and heat treated dry sausage...
Limitations and Considerations in Air Sampling, Sample Analysis and Result Interpretation for Airborne Mould Spores by Jackson Kung’u Airborne mould material particularly spores are recognized allergens at normal concentrations to an estimated 20% of the population (Kendrick, 2000). It is not always possible to establish a correlation between mould spore counts in the environment and the presen...
In this investigation a new model was developed to calculate gas pressure at the melt/foam interface (Gap) resulting from foam degradation during mould filling in the Lost Foam Casting (LFC) process. Different aspects of the process, such as foam degradation, gas elimination, transient mass, heat transfer, and permeability of the refractory coating were incorporated into this model. A Computati...
The article reviews the properties of the Galactomyces geotrichum species, the mould that is most important for the dairy industry. G. geotrichum mould has been isolated from milk, cheeses and alcoholic beverage. Its presence in food products makes it possible to obtain a characteristic aroma and taste, which corresponds to the needs and preferences of consumers. G. geotrichum plays an importan...
Bone marrow has already been described as an enrichment site for several antigen-specific T lymphocytes, but the presence of mould-specific T cells has never been investigated in the bone marrow. We have previously demonstrated that mould-specific T cells emerge in the peripheral blood of patients with invasive fungal infections (IFI) but tend to become undetectable after disease resolution. In...
We have cloned an actin-encoding cDNA from the dimorphic fungus Histoplasma capsulatum, an important pathogen of humans. The predicted amino acid sequence as well as the general codon pattern of Histoplasma actin revealed the highest degree of similarity to the actin of the filamentous ascomycete Aspergillus nidulans. Southern blot analysis determined that actin was encoded by a single copy in ...
