Multiple output differential OTA with linearizing bulk-driven active-error feedback loop for continuous-time filter applications
PublikacjaA CMOS circuit realization of a highly linear multiple-output differential operational transconductance amplifier (OTA) has been proposed. The presented approach exploits a differential pair as an input stage with both the gate and the bulk terminals as signal ports. For the proposed OTA, improved linearity is obtained by means of the active-error feedback loop operating at the bulk terminals of the input stage. SPICE simulations...

Uncertainty of Postmortem Time Estimation Based on Potassium Ion Determination in Vitreous Humor Using Potentiometric Ion-Selective Electrode and Microwave-Induced Plasma with Optical Emission Spectrometry Methods
PublikacjaThere is a need for a reliable and independent evaluation and confirmation of the post-mortem interval (PMI) based on objective factors other than only postmortem changes or temperature measurements. Estimating the PMI by examining the concentration of potassium ions in the vitreous humor (VH) has a tradition in forensic toxicology dating back to the mid-20th century. So far, the methods for determining the presence of potassium...

Islam versus Architecture and Urban Order in the Time of Changes : Social and Cultural Aspects of Housing Architecture Transformation in the Arab Countries of Northern Africa
PublikacjaArtykuł jest omówieniem obserwacji tradycyjnej i współczesnej zabudowy mieszkaniowej przeprowadzonych przez autora w Algierii (1978) i Libii (1984-1988). Realizowane obecnie struktury i kultywowane formy zamieszkiwania wzorowane są na rozwiązaniach ''zachodnich'' odmiennych od rozwiązań tradycyjnych. Są one niedostosowane do wymogów środowiska naturalnego i pozostają w sprzeczności z zasadami określonymi przez Koran i sunnę. Rozdźwięk...
