Dugotrajne promjene u koncentracijama polutanata u zraku - istraživanje skrivenih ciklusa

Svrha ovog rada bila je pronalaženje nevidljivih ciklusa u koncentracijama onečišćivača i vrijednostima praćenih meteoroloških parametara na području Slavonskog Broda. Istovremeno su istraženi mogući utjecaji meteoroloških parametara na prostornu i vremensku dinamiku tih onečišćivača. Na temelju mjerenja onečišćujućih tvari na mjernoj postaji u Slavonskom Brodu provedena je Fourierova analiza kvalitete zraka u 2010. godini. Analiza je obuhvatila sljedeće onečišćivače: H2S, O3, NO2. SO2 i lebdeće čestice (PM2.5). Provedena je i Fourierova analiza podataka satnih koncentracija meteoroloških parametara:temperature, relativne vlage i brzine vjetra. Pored uobičajenih,rezultati provedene Fourierove analize ukazali su na postojanje zajedničkih varijacija među onečišćivačima, ali i postojanje zajedničke periodičnosti između koncentracija nekih onečišćivača i praćenih meteoroloških parametara.The purpose of this paper was to analyze pollutant concentration in urban and industrial aria of Slavonski Brod so as determine correlation with meteorological parameters. Due to results of pollution measurements, Fourier analysis was applied to these time series. H2S, O3, NO2. SO2 and PM2.5 particles were measured in 2010. During that time hourly concentration of pollutants were measured and their cycles were observed. This paper confirms the existence of common peaks in the period region which most probably are connected to meteorological influences

Possibilities of applying CORONA archive satellite images in forest cover change detection: Example of the Fruška Gora Mountain

This paper examines the possibilities, advantages and limitations of the use of high resolution archive satellite images in evaluation of forest and other land cover changes, based on research in the sample area of the Fruška Gora mountain (Serbia). Satellite images available from the declassified archives of CORONA program were used to assess the extent of forest cover in the past. By comparing the resulting datasets with newer images, changes in the forest coverage can be detected and reconstructed for a period of more than 40 years. Despite many limiting factors, the images provided valuable information about the state of the forest cover in the past. The methodology used can be utilized in other similar areas, where no other, more precise source is available about forest coverage, as a means of reasonably inexpensive and time efficient assessment of forest cover and other land use changes in the past five decades

CCDC 2190057: Experimental Crystal Structure Determination

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures
