AB  - Ambrosia artemisiifolia je ekonomski štetna korovska vrsta pri čijoj visokoj brojnosti prinosi useva mogu biti značajno umanjeni ili potpuno uništeni. Pored A. artemisiifolia u Srbiji lokalno je prisutna i Ambrosia trifida. Po habitusu je robusnija od A. artemisiifolia, čiji primerci zabeleženi na području centralne Bačke (Srbija) dostižu visinu i do 4 m. S obzirom da je A. trifida u ekspanziji pretpostavlja se da će pričinjavati mnogo veće štete od A. artemisiifolia (kada se nađu na istom arealu), kako u biljnoj proizvodnji tako i u ekosistemu potiskujući autohtone vrste i izazivajući alergijske smetnje kod ljudi i životinja. Cilj ovih istraživanja je da se odredi koliki ie uticaj A. artemisiifolia na vegetativni prinos A. trifida u uslovima njihove koegzistencije.
Eksperiment ie postavljen po modelu zamenjujućih serija (Replacement Design) gde je praćena  kompetitivna interakcija izmedu A. artemisiifolia (AA) i A. trifida (AT). Ogled je postavljen u šest tretmana (potpuno slučajan blok sistem u četiri ponavljanja) sa različitim proporcijama biljaka AA i AT po m2 (a-10:0; b-8:2; c-4:6; d-6:4, e-2:8 i f-0:10). Tokom sezone (2016) kroz tri ocene mereni su vegetativni parametri AT (visina, širina, broi listova biljaka, suva masa) i upoređene su vrednosti merenih parametra iz svih tretmana sa tretmanom F.
Prosečne visine biljaka u prvoj oceni kretale su se od 37,19 cm do 51,25 cm, u drugoj oceni od 70,87 cm do 99,95 cm i u trećoj oceni od 86,90 cm do 155 cm, pri čemu su statistički značajne razlike (P<0,01) zabeležene izmedu F i E (l ocena), F I E, F i D (Il ocena) i između F i E (Ill ocena). U prvoj i drugoj oceni bilike iz varijante F su dostigle maksimalnu visinu, dok je u trećoj oceni maksimalna visina zabeležena u varijanti B. Prosečna širina biljaka kretala se u rasponu od 18,5 cm do 20,5 cm (I ocena), od 16,094 cm do 20, 15 cm (ll ocena) i od 17,25 do 34 cm (Ill ocena). Kao i u slučaju visine, maksimalne vrednosti u prvoj i drugoj oceni su utvrđene za F varijantu, a u trećoj oceni za B varijantu dok je u trećoj oceni najizraženija iskazana širina biljaka u B tretmanima. Veoma značajne statističke razlike (P<0,01) ispoljile su se kroz sve tri ocene u poređenju tretmana F sa E i D varijantama. Broj listova u prvoj oceni u proseku iznosio je od 8,03 do 9,625, u drugoj od 11,875 do 13,125 gde je AT najviše listova formirala u tretmanu F, pri čemu su statistički značajne razike (P < 0,01) konstatovane samo u prvoj oceni između F i C I između F i E. U trećoj oceni prosečan broj listova bio je najveći u B varijanti. Prosečne vrednosti suve mase u prvoj oceni kretale su se u opsegu od 5.8 g do 11,49 g, u drugoj 7,4 g do 11.63 g a u trećoj 00 8.90 g do 14,15 g.
Odnos između tretmana razlikovao se u poređenju sa drugim parametrima što je verovatno rezultat različitog odosa stabljike i težine listova biljaka u različitim tretmanima. Dobijeni rezultati pokazali su izrazitiju konkurenciju A. trifida kao i njenu invazivnost u koegzistenciji sa A. artemisiifolia.

AB  - Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) of constituent metal oxides, at 1000 degrees C in air. In addition, two closely related perovskites LaFeO3 (LF) and LaTi0.5Mg0.5O3 (TM (50:50)) were synthesized in the similar way. Using MCA method, perovskites were obtained in rather short time and at room temperature. The samples were characterized by X-ray powder diffraction (XRPD), Xray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS), temperature programmed desorption of oxygen (TPD), Mossbauer spectroscopy, BET surface area measurements and tested in methane deep oxidation. According to XRPD analysis all synthesized samples are almost single perovskite phase, with trace amounts of La2O3 phase. Data of Mossbauer spectroscopy identify Fe 31 in octahedral coordination. The activity of perovskite in methane deep oxidation increases in the order TM (50:50)  lt  MF series  lt  TF series. Higher activity of TF samples in respect to MF with similar Fe content can be related to the structural characteristic., mainly to the presence of predominantly most labile oxygen species evidenced by TPD at lowest temperature of oxygen evaluation. In used experimental conditions, the Fe substituted perovskite are thermal stable up to the temperature of 850 degrees C. The stability of Fe active sites is probably the most important parameter responsible for thermal stability of perovskite, but the atomic surface composition also should be taken into account.

AB  - Perovskite type catalysts La0.7Sr0.3Cr1-xRuxO3 (0.025  lt = x  lt = 0.100) were synthesized by annealing a mixture of metal oxides and carbonates gradually up to 1000 degrees C in air, and characterized by XRPD, XPS, TPD, SEM-EDS and the van der Pauw method. The CO oxidation activity was investigated in a differential recycle reactor. According to the XRPD results, all samples achieved a perovskite structure, with a small presence of SrCrO4 phase. The XPS results revealed that the surface composition of all samples differed considerably from the stoichiometric value with ail important segregation of strontium and mainly ruthenium with regard to chromium at the surface of the catalysts. The sharp decrease of resistivity with increasing surface concentration of ruthenium and the independence of the resistivity on temperature for the sample with x = 0.100 imply the possible presence of SrRuO3, La-Ru-O and highly dispersed RuO2 (invisible by XRPD), known as good electric conductors, at the surface. The CO oxidation activity increases with increasing the degree of substitution (x). The surface concentrations of ruthenium are almost the same in the samples with x = 0.075 and 0.100. Those samples showed the similar values of resistivity in whole investigated temperature ram,e and very close CO oxidation activity. which indicates that the concentration of Ru4+ in the surface region and its stability are determining factors for the CO oxidation activity. The main results of this study are that ruthenium perovskites have a high thermal stability and CO oxidation activity.
