ADVANTAGES OF BIOREACTOR IN THE PROCESS OF CONTROLLED COMPOSTING BIOWASTE
The process of composting of biowaste, while ensuring the necessary conditions and depending on the composition of composted material can be carried out in natural conditions. If we want to influence the speed and stability of the process of degradation of organic matter from biowaste, it is necessary that one or more influencing factors control th...

AUSTEMPERED DUCTILE IRON
Austempered Ductile Iron is a class of ductile iron subjected to a specific heat treatment process (austenitization and austempering). The heat treatment gives to that type of Ductile Iron an excellent mechanical properties and an especially good strength-to-weight ratio. However, designers in most cases are unfamiliar with this material that can c...

DIAGNOSTIC OF WIND POWERS
Each system requires regular maintenance including wind power. Modern maintenance of wind powers is based in the diagnosis of the state of the wind power, which is realized through measuring parameters of wind power system and data processing by the established methods. This paper presents the modern methods used to control the state of the wind fa...

FRACTURE MODE-MIXITY IN SYMETRICAL BEAM SPECIMENS: FPZ LENGTH INFLUENCE
Mixed-mode fracture in delamination test utilizing double cantilever specimens loaded with bending moments is investigated in the paper. FEM simulations are performed using cohesive zone model where different configurations of test loadings and two critical fracture energy values, ie. two fracture process zone lengths, are considered. Fracture ener...
