Global Complex Roots and Poles Finding Algorithm Based on Phase Analysis for Propagation and Radiation Problems
PublicationA flexible and effective algorithm for complex roots and poles finding is presented. A wide class of analytic functions can be analyzed, and any arbitrarily shaped search region can be considered. The method is very simple and intuitive. It is based on sampling a function at the nodes of a regular mesh, and on the analysis of the function phase. As a result, a set of candidate regions is created and then the roots/poles are verified...

Metody oznaczania pestycydów w atmosferze w fazie gazowej i w pyle zawieszonym
PublicationW przypadku analizy próbek powietrza konieczne jest zastosowanie aparatury oddzielającej fazę gazową od cząstek stałych. Możliwe jest wtedy oznaczanie pestycydów osobno w obu fazach (w fazie gazowej oraz w pyle zawieszonym). Pierwszym etapem analizy w przypadku oznaczania pestycydów w powietrzu jest izolacja pestycydów z matrycy wraz ze wzbogacaniem analitów, a następnie ekstrakcja i oczyszczanie ekstraktu połączone najczęściej...

The mediational role of future and past time perspectives in the relationship between negative affectivity and sense of coherence
PublicationSense of coherence (SoC) can promote positive coping, and one of its most prominent negative correlates is negative affectivity (NA). In the current study, we hypothesized that future and past time perspectives (TPs) will mediate the relationship between sense of coherence and negative affectivity, and the inverse relationship. The study was questionnaire-based, performed online. N = 719 participants aged 25-45 from...
