  - Rok 2014

  Zmiany demograficzne następujące w ostatnich latach w krajach rozwiniętych stawiają nowe wyzwania przed badaczami i praktykami rynku pracy. Jedną z najbardziej zauważalnych konsekwencji „starzenia społeczeństw” jest wydłużenie czasu bierności zawodowej. Jednocześnie w wolniejszym tempie występuje proces wydłużenia czasu aktywności zawodowej. Z punktu widzenia stabilności systemu emerytalnego istotne jest zatem określenie przyczyn...

  The production of high-added value reclaimed rubber (RR) is of great signifi-cance for the sustainability of rubber industries. To green recycle waste rub-bers and broaden the application of RR, a RR material with potentialreinforcing and plasticizing effects on nature rubber (NR) composites are pre-pared by a thermo-oxidative reclamation process. The reclamation degree ofRR is controlled by adjusting the content of soybean oil....

It has been reported that butyrylcholinesterase (BChE) also accumulates in the brain Aβ plaques in AD. We have previously found that the BChE substitution in 5′UTR caused an in-frame N-terminal extension of 41 amino acids of the BChE signal peptide. The resultant variant...

  Hydrolysis is an important process in biological wastewater treatment and has been known as the rate limiting step in organic carbon removal from municipal or industrial wastewater. The biodegradation of XS is initiated by hydrolysis which is an integral part of activated sludge models, such as the Activated Sludge Model no. 2d (ASM2d). The aim of this study was to evaluate different concepts of modeling the hydrolysis process...
