Spare parts are parts of machines, plants and equipment (technical systems) that should be available for replacement when canceling them for various reasons - breaks, abrasion and deformation. By replacing them, the observed technical system places itself in the possibility of functional use. In order to enable the possibility of eliminating failur...

In this paper, a model based on numerical solution of two ordinary differential equations is used to obtain the water level in the surge tank and the static pressure in the headrace tunnel – the properties of essential importance for the functioning of the water supply system during the turbine shut-off. The model allows a fast and reliable s...

Two different system modelling can be distinguished in life cycle assessment: attributional and consequential. Attributional modelling is used to describe the present state of the examined system and is characterised with use of allocation, no substitutions, market average suppliers, and cut-off principle. Consequential modelling is used to describ...

Cranioplasty is the surgical repair of a bone defect in the skull that is left behind after a severe injury or previous operation. It is usually done to protect underlying brain tissue, reduce local pain and to improve the cranial vault aesthetics. Cranial prostheses can be made from different types of materials: autologous bone, titanium, ceramics...

Contraction is a part of a wind tunnel that has the greatest impact on the air flow quality in the test section. The constriction ratio, the cross section shape, the length and wall shape are constructive parameters that influence the uniformity of the flow, the flow turbulence intensity, the flow rotation angularity, the appearance of the flow sep...

The remains of natural and artificial materials in the textile industry are a problem in the technological process because it is a continuous production of waste and related to the need for everyday care. In Bosnia and Herzegovina there are currently no facilities for the material utilization, recycling or reuse of textile waste. Municipal waste di...

The paper analyzes the behavior of the plastic container during the buckling, ie during the load effect on the containers. The analysis was experimentally performed on several different types of containers. The container material is polypropylene. Experimental determination of pressure force and corresponding deformation was performed in thelaborat...
