Simulacija u metalurgiji

Die vorliegende Veröffentlichung umreißt in groben Zügen die Grundlagen der Simulation sowie den Weg vom realen Problem zum Modell. An einigen Fallbeispielen ist der Einsatz der Simulation in der Metallurgie gezeigt. Ablaufsimulation, Parameterstudien sowie Simulationen zu Produkteigenschaften werden erklärt. Die Entwicklung von neuen Verfahren mittels der Simulation ist ebenfalls beschrieben.Predočeni rad opisuje u grubim crtama kao i put od realnog problema do modela. Na primjerima nekih slučajeva prikazuje se primjena simulacija u metalurgiji. Objašnjava se simulacija toka, proučavanje parametara kao i simulacija glede svojstava proizvoda. Također je opisan razvoj novih postupaka pomoću simulacije

An overview of the utilisation of microalgae biomass derived from nutrient recycling of wet market wastewater and slaughterhouse wastewater

Microalgae have high nutritional values for aquatic organisms compared to fish meal, because microalgae cells are rich in proteins, lipids, and carbohydrates. However, the high cost for the commercial production of microalgae biomass using fresh water or artificial media limits its use as fish feed. Few studies have investigated the potential of wet market wastewater and slaughterhouse wastewater for the production of microalgae biomass. Hence, this study aims to highlight the potential of these types of wastewater as an alternative superior medium for microalgae biomass as they contain high levels of nutrients required for microalgae growth. This paper focuses on the benefits of microalgae biomass produced during the phycore-mediation of wet market wastewater and slaughterhouse wastewater as fish feed. The extraction techniques for lipids and proteins as well as the studies conducted on the use of microalgae biomass as fish feed were reviewed. The results showed that microalgae biomass can be used as fish feed due to feed utilisation efficiency, physiological activity, increased resistance for several diseases, improved stress response, and improved protein retention
