REDUCTION OF MOTOR VEHICLES EMISSION BY USING NATURAL GAS AS AN ENERGY SOURCE

As the automotive industry perceived negative effects of road transportation to the environment, it has intensively worked on new technological solutions during several decades, with the goal of reducing the negative effect of vehicles to the environment. That is why priorities of contemporary and future development of vehicles, engines and accompanying equipment are the following: reduction of fuel consumption and reduction of emission of exhaust gases. One of the ways to solve current tasks of the automotive industry is the use of alternative fuels, that is, alternative energy potentials. This paper analyzes natural gas as alternative fuel for motor vehicles. After description of basic physical and chemical properties and the analysis of use of natural gas as a fuel for ICE, this paper presents reduction of motor vehicles emission by using natural gas as a fuel

IMPACT OF IRRIGATION REGIME AND APPLICATION OF KAOLIN ON THE STOMATAL CONDUCTANCE AND LEAF WATER POTENTIAL OF PEPPER AND TOMATO

The effect of different irrigation regimes and the application of kaolin on stomatal conductance and leaf water potential of pepper (Capsicum annuum L.) and tomato (Lycopersicon esculentum Mill.), is discussed in the paper.The experiment was set up by a completely randomized block system with three replications. The peppers were observed in three, and tomatoes in two treatments of irrigation regimes. The kaolin treatments of both crops were: a) control without kaolin (C) and 5% kaolin suspension (K).The results of these studies show that the application of deficit irrigation treatments and kaolin treatment have no statistically significant effect on stomatal conductance and leaf water potential of pepper and tomato plants

Spectroscopic investigation of two Serbian icons painted on canvas

A multianalytical study of two Serbian icons, The Virgin and Child and St. Petka, painted on canvas by unknown authors was performed in order to identify the materials used as pigments, binders and the ground layer. The investigated icons belong to the Museum of the Serbian Orthodox Church in Belgrade. Samples, collected from different parts of the icons, were analysed by: optical microscopy (OM), energy dispersive X-Ray fluorescence (EDXRF), Fourier transform infrared (FTIR) and micro-Raman spectroscopy. The obtained results revealed the presence of the following pigments: Prussian Blue, ultramarine, Green Earth, iron oxides, Lead White and Zinc White. Linseed oil was used as the binder. The materials used for the ground layers were gypsum, calcite, baryte and Lead White. The gilded surface of the icon The Virgin and Child was made of gold. The gilded surface on the frame of this icon was made of imitation of gold, i.e., Schlagmetal, since EDXRF spectroscopy showed the presence of copper and zinc, while gold was not detected. Based on the style and the consideration of an art historian, as well as on the obtained results for the corresponding pigments and binder, both icons were most probably made at the end of 19th or the beginning of the 20th century

Zn concentrations in wheat grains along the gradient of native Zn soil availability in Serbia

Zinc (Zn) is an essential microelement for plants and also an important nutritional and health factor in humans. As a consequence of low Zn availability in soils, nearly half of the world's population suffers from Zn malnutrition. Zn deficiency has serious implications for human health (e.g. impairments in physical development, immune system, brain function and learning ability) and thus for the overall economy of a country; it is most severe in nations who depend on cereals as the main staple food. A critical Zn concentration in the whole grain for humans that depend on cereal based diets is 24 mg kg-1 dry matter. Research focused on increase of Zn content in cereals (biofortification), is the strategic priority in many countries. In Serbia however, the awareness of this problem is lacking, and no systematic survey of Zn availability in soi ls and concentrations in cereal grains has been undertaken so far. Our study included 156 grain samples of the two major bread wheat varieties (Simonida and NS 40S) collected at 89 localities throughout Serbia. We analyzed soil pH, available Zn and grain Zn concentration together by principle component analysis and multiple linear regression. Wheat varieties did not differ in ability to accumulate Zn in grains. Both soil pH and available Zn concentration were the nominally significant predictors for grain Zn concentration and explained about 12 and 9% of the encountered variation, respectively. Zn concentration below the critical limit (24 mg kg-1) was found in 58% of grain samples (values in the range 11-61 mg kg-1, median only 21.3 mg kg-1), while in only 14% of soil samples the available Zn was below the critical value (05 mg kg-1). The most severe lack of Zn in grains (below 18 mg kg-1) was observed in samples from the major production regions of bread wheat (e.g. Pancevo, Vrbas and Sremska Mitrovica). The alarming results of this survey indicate that Serbia urgently needs a strategy for Zn biofortification, primarily through a breeding program to enhance Zn efficiency as a sustainable alternative to application of Zn fertilizers

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
