100%

Kentli F. , Bozkurt I. , Onat B.

tom R. 89, nr 5

6-10

The aim of this study is to compare the flux distributions obtained using the experimental method and calculated by FDM. For this purpose, first the design and manufacture of the test transformer which is to be used in the experimental study as well as the measuring coil which is to be used in measuring the prepared fluxes, and then the calculated flux values. Both proposed assessment methods can be used for in-service inspection of the structural integrity of ferromagnetic structures.

W artykule porównano rozkład strumienia otrzymany drogą eksperymentalną i poprzez obliczenia FDM. Zaprojektowano wykonano testowy transformator w dołączonymi cewkami pomiarowymi.

Indoor PM2.5 levels have been measured in the Cerrahpasa Medical Faculty during the autumn of 2007 between September and December. PM2.5 was measured for a period of 8 h during the workday (8.30 a.m.-4.30 p.m.). The maximum PM2.5 level equal to 388.5 μg/m3 was found at the administrative building. The highest average PM2.5 was 160.1 μg/m3 measured at the waiting room of central laboratory.
