AB  - 24-epibrassinolide (24-EBL) is plant steroid hormone that can regulate several physiological effects in plants, including promotion of cell growth and induction of heat stress tolerance. The purpose of this work is to investigate the influence of various concentrations of 24-EBL on the dehydration mechanism of seedlings of two maize hybrids (ZP434 and ZP704). Control and treated samples were subjected to isothermal conditions for dehydration processes. The effects of carbohydrates and mineral contents on the possible changes in the dehydration mechanism (from kinetics standpoint) were investigated. Comparing control samples to samples treated with 24-EBL, it was found that different dehydration mechanisms exist The differences arise from the influence of 24-EBL, that causes a significant increase of phosphorus values for ZP704, whilst the reverse was identified for ZP434. It was assumed that the plumule sensitivity to dehydration stress originates from the interaction of water with primary amino groups as cations in polyamines, for lower concentrations of 24-EBL. It was found that the temperature variation (105-130 degrees C) leads to situations where trehalose does not arrive fast enough to "replace the water", because its handicap to binds (by hydrogen bonds) to biomolecules instead of water. It was found that 24-EBL cause changes of carbohydrates properties, which are important for the defense mechanism from environmental stresses. (C) 2018 SAAB. Published by Elsevier B.V.

AB  - Due to the frequent use of fossil fuels, which has negative effects on the environment, there is a need to find a new, environmentally acceptable replacements for fossil fuels. One of the possible replacement is the inclusion of green technologies, in order to obtain the type of fuel that would be acceptable from an environmental and economic point of view. Biodiesel represents renewable and less toxic substituent for fossil fuels, which consists of esters of higher fatty acids and depending on the environmental conditions, can be manufactured from various types of oils, both plant and animal origin. Since corn is one of the most cultivated plants in Serbia, the research included the transesterification reaction of corn oil on a heterogeneous catalyst. The paper examined the activity of heterogeneous base catalyst (CaO/γ-Al2O3) and the influence of various parameters on the conversion of corn oil. From the optimization of process parameters, it was found that the optimal conditions for transesterification of corn oil to 25% CaO/γ-Al2O3: molar ratio of methanol to oil 1:12; stirring speed 900rpm; reflux temperature of the methanol; reaction time of 6 hours; the amount of catalyst in the reaction of 5wt.%.
AB  - Zbog sve učestalijeg korišćenja fosilnih goriva, koja imaju nepoželjne efekte na životnu sredinu, postoji potreba za pronalaženjem nove, ekološki prihvatljive zamene za fosilna goriva. Jednu od mogućih zamena predstavlja uključivanje zelenih tehnologija radi dobijanja vrste goriva koje bi bilo prihvatljivo sa ekološkog i ekonomskog aspekta. Bidizel predstavlja obnovljiv i manje toksičan substituent za fosilna goriva, koji se sastoji od estara viših masnih kiselina i u zavisnosti od podnevlja, može se proizvoditi od različitih vrsta ulja, kako biljnog, tako i životinjskog porekla. Obzirom da je kukuruz jedna od najviše gajenih vrsta biljaka u Srbiji, istraživanja su obuhvatila reakciju transesterifikacije kukuruznog ulja na heterogenom katalizatoru. U radu je ispitivana aktivnost heterogenog baznog katalizatora (CaO/γ-Al2O3) kao i uticaj različitih parametara na konverziju kukuruznog ulja. Optimizacijom procesnih parametara je ustanovljeno da su optimalni uslovi za transesterifikaciju kukuruznog ulja na 25% CaO/γ-Al2O3: Molarni odnos metanola prema ulju 1:12; brzina mešanja 900rpm; temperatura reakcije refluks metanola; vreme reakcije 6 sati; količina katalizatora u reakciji 5%.
