Hieronim Wierzbowski herbu Jastrzębiec był starostą szadkowskim w latach 1655–1665. Dzięki monarszej protekcji piął się po szczeblach kariery urzędniczej, od chorążego większego łęczyckiego (1648–1652), do wojewody sieradzkiego (1661

The performance of uncooled photodetectors operating in the middle and long wavelength spectral range is limited by the noise originated from thermal generation and recombination processes in semiconductors. The noise level exponentially increases wi
