A study of the spatial distribution of seismicity parameters is undertaken along Turkey and its vicinity, using the Gumbel’s third asymptotic distribution of extreme values (GIII). The data set used spans of 111 years (1900-2010). The seismicity of the whole region is subdivided into equal area mesh of 1° lat. × 1° long. Various seismicity parameters examined, resulted from the application of the GIII method. The results show a quite good correlation between the seismicity parameters and the tectonic regime of the studied area. For instance high values concentrated around North Anatolian Fault. The x2-test is applied throughout the whole process and in every stage of GIII, in order to check the accuracy of the obtained results. The spatial distribution of upper-bound (ω) formed a W-shape pattern, which shows the difference in the mechanical structure of the materials in the examined area.A study of the spatial distribution of seismicity parameters is undertaken along Turkey and its vicinity, using the Gumbel’s third asymptotic distribution of extreme values (GIII).

Skonstruowano model analizy kowariancji dla poziomu emisji tlenków azotu NOx w spalinach silników S-4002 zasilanych mieszankami paliwowymi mineralnego oleju napędowego ON z dodatkiem estru oleju rzepakowego RME. Jako zmienną niezależną (grupującą) obrano udział procentowy RME w paliwie. Za zmienną towarzyszącą obrano moc efektywną Ne. Badano wzajemne położenie odpowiednich krzywych opisujących zmienną zależną - poziom NOx. Dodanie estru oleju rzepakowego RME przy prędkości obrotowej 2000 obr*min-1 powoduje wzrost poziomu emisji tlenków azotu o około 45,6 jednostek ppm. Emisja wzrasta wraz ze wzrostem mocy efektywnej Ne silnika.

The article presents an analysis of NOx emission levels in the fumes of S-4002 engines fed with fuel blends composed of the mineral engine oil ON with an addition of rape oil ester RME in various proportions. As the independent (grouping) variable the percentage of RME in the fuel was chosen. The associated variable was the effective power Ne. The mutual position of respective curves describing the dependent variable NOx level was examined. The addition of the rape oil ester RME at the rotational speed of 2000 rpm results in the increase of nitric oxides emission level by approximately 45.6 units ppm. The emission increases together with the increase of the engine effective power Ne.
