Possibility of discrimination of sour substances by liquid membrane oscillators
PublikacjaZbadano wpływ kwaśnych substancji oraz stężenia kwasu cytrynowego na charakterystyki oscylacyjne oscylatorów z membraną ciekłą (nitrometan) zawierających kationowy lub anionowy surfaktant. Zależą one od rodzaju substancji smakowej. Wyznaczono atraktory w przestrzeni dwuwymiarowej metodą opóźnienia czasowego. One mogą być użyte jako tzw. ''Jingerpmint'' do rozróżniania substancji kwaśnych. Jednakże nie znaleziono bezpośredniej korelacji...

Integrated Sectors - Diversified Earnings: The (Missing) Impact of Offshoring on Wages and Wage Convergence in the EU27
PublikacjaThis paper assesses the impact of international outsourcing/offshoring practices on the process of wage equalization across manufacturing sectors in a sample of EU27 economies (1995-2009). We discriminate between heterogeneous wage effects on different skill categories of workers (low, medium and high skill). The main focus is on the labour market outcomes of vertical integration, so we augment a model of conditional wage convergence...
