17 sierpnia w Dzienniku Urzędowym Unii Europejskiej opublikowana została decyzja wykonawcza Komisji Europejskiej ustanawiająca konkluzje BAT dla dużych obiektów energetycznego spalania (LCP). Zakończył się tym samym rozpoczęty w 2011 r. proces rewizji starego Dokumentu Referencyjnego BAT (BREF) i rozpoczął czteroletni okres dostosowawczy, który obejmuje wszystkie obiekty - źródła energetycznego spalania o sumarycznej mocy w paliwie przekraczającej 50 MWt, liczonej zgodnie z zasadą łączenia - na wspólnym kominie.

Nowadays complex demands are required from products to be reliable and provide their functions safe and without impacts on the environment. When deciding on the purchase of a product, the deciding factor is not only the acquisition costs, but also operating costs, preventive maintenance and corrective maintenance costs and the disposal costs as well. The manufacturer must design a product that will be failure-free and competitive, with the costs as low as possible, which can be achieved through the optimization of acquisition costs, cost of ownership and disposal costs. Ideally, this process should start from the very beginning of the product life and should be evolving with respect to all of the costs to be incurred throughout the life cycle. The aim of the work was to create own methodology for the calculation of costs and profits for the life cycle of a rail vehicle in terms of manufacturer and the operator to comply with all the relevant principles of the EN 60300-3-3 standard. The created methodology was implemented into the MS Excel software. The data on costs and profits during the life cycle of a tram were input into the software data. The data are mutually interconnected and may be monitored for any individual change that will affect other costs or profits for life cycle of a tram.

Bez dostosowania do wymagań konkluzji BAT od 2019 r. instalacjom spalania grozi brak zgody na ich dalszą eksploatację. Trzeba rozpocząć przygotowania zmierzające do oceny i zapewnienia zgodności instalacji z konkluzjami BAT. Formułując te założenia, warto przewidywać gotowość dostosowania się do następnego zaostrzenia wymagań ochrony środowiska, które może nastąpić za 8 lat przy kolejnej rewizji BREF-u LCP.

The 11 holes locking compression plate (LCP) is a type of fixator which is currently used in orthopedic surgeries for fixing fractures of long bones. 8 styles of screw positioning on this plate are possible so each orthopedist may use one of them during operations. The aim of the current study was the analysis of diversified screw arrangement on the mentioned LCP for fixation of medial transverse fracture of tibia considering time- varying properties of bone callus in 16-weeks curing duration. Stress shielding effects were also considered. Finite element method using Mimics 10.01, Solid works 2012 and Abaqus 6.11-1 software have been applied. Modeling of bone was done based on computer tomography (CT) scan of human right tibia and four types of forces have been loaded on intact bone and the same was loaded on fixated fractured ones in 8 treatments of fixation. Stresses in bone, plate and screws, also gap or callus strains and stiffnesses in 5 terms of curing duration in all of the treatments have been investigated and compared together using new defined parameters. Finally the preferred treatment was concluded. Results of this study may be used by orthopedists in applying such a fixator for fixation of tibia and other fractured long bones.
