The current study included the investigation of several metals and their distribution in urban soils from parks green areas city Belgrade. were sampled January February 2008. concentrations Cd, Co, Cu, Pb, Mn Zn measured, as well pH values organic matter contents. obtained results showed that there was a significant level contamination some samples, especially with lead, it most probably caused by anthropogenic activities, mostly traffic. compared National legislation Netherlands standards....

This study investigates the potential of fatty acid profiles various industrial crops to discriminate them based on their botanical origin. All analyzed plants were grown experimental fields at Rimski Šančevi, Republic Serbia. Cereal samples (corn, wheat, barley, and oat) milled into flour lipid fractions extracted using n-hexane. Lipid oilseed (rape, flax, safflower, pumpkin) obtained by mechanical pressing. The acids present in fractions, derivatized corresponding volatile methyl esters...

Various cultivars of different cereal and pseudocereal species (9 wheat, 8 barley, 1 rye, 3 oat, 2 triticale, spelt, 12 corn, amaranth 9 buckwheat cultivar samples) were milled into flour, extracted using n-hexane, derivatized with trimethylsulfonium hydroxide solution, subjected to GC? ?MS analysis. Fatty acid methyl esters non-saponifiable compounds (phytosterols, ?-tocopherol squalene) identified by comparing mass spectra the Wiley MS library. A binary system was applied in further data...

This study represents a new strategy for discrimination of 59 samples various cold-pressed, virgin and refined edible vegetable oils according to the corresponding botanical origin. Samples were produced from 17 plant species: olive, sunflower, safflower, flax, pumpkin, sesame, hemp, walnut, hazelnut, almond, grape, black cumin, apricot, plum, soybean, wheat rapeseed. A GC/MS device performing in ion current (IC) mode, combined with multivariate clustering, was employed analysis....

The Protocol on Ozone Depleting Substances (ODS) was signed in 1987 Montreal. main goal of the protocol is international consensus and action regarding drastic decrease production use these substances, which results increased UV radiation consequently has a negative impact human health ecosystem. Besides review ?legal technical? implementation until now withdrawal ODS from use, this paper specially stresses analysis available research positive health, correlation with Montreal (MP). Due to...

The environmental issues and quality of life in the Republic Serbia are starting to take place that deserve a long time ago. right healthy environment availability information concerning guaranteed by Constitution Aarhus Convention belong fundamental human rights, now widely accepted world our country. This approach 'democratization' field means includes media broadest sense order justify their social role justification. Awareness necessity preserving has been present conscientious, but few...

In this paper, we propose a Programmable Intraflow-based IoT Botnet Detection (PI-BODE) system. PI-BODE is based on the detection of Command and Control (C&C) communication between infected devices botmaster. This approach allows detecting malicious before any attacks occur. Unlike majority existing work, method analysis traffic intraflow statistical parameters. Such an makes more scalable less hardware demanding in operation, while having higher or equal level accuracy compared to...

We propose Combinatorial Optimization based Consensus Protocol (COCP) that considers efficient use of energy in Blockchain (BC) consensus protocol on Proof-of-Useful-Work (PoUW) concept. Instead classical cryptographic puzle, it involves dealing with hard real-life combinatorial optimization (CO) problems submitted by BC participants called customers. Two sources rewards are provided for miners, one related to adding a new block and the other solving an instance CO problem. The main issues...

The issue of the perspective survival and production sufficient amounts quality health-safe food in future is on top contemporary society?s priority list. Limitation non-renewable renewable resources (as well as dramatic increase population world climate changes) additionally makes reaching this goal difficult. Republic Serbia (and especially Province Vojvodina) sense very significant a region suitable for kind production, not only domestic needs, but also placement these products market....

A consequence of the high concentrations population in big cities is growth amount municipal waste generated. This has resulted an accelerating need for developing as efficient a management system possible on local level, based legal requirements and rules good conduct within this field. The city Belgrade used case study analyzing existing problem (based Waste Management Plan), elements operational performances (special disposal), possibilities improving by contemporary technical managerial...

The insulation system of rotating machines high importance has always been the object thorough screening with certified test methods that are getting constantly improved. Low-power and 'less important' like voltage motors, rarely subjected to detailed electrical tests because low resources allocated for their maintenance. introduction EDA methodology in practice creates conditions reliable complete diagnostics stator windings big machines, as well fast, easy inexpensive low-power (i.e. HV...

During regular operation, power transformer windings are continuously exposed to electromechanical stresses and vibrations. Surges during lightning or short circuits may cause the weakening of mechanical structure reinforcing parts core windings. Any distortion projected geometry winding will reduce its ability withstand subsequent overstressing, which can lead a large deformation major system faults. This paper presents an analysis frequency response (Sweep Frequency Response Analysis -...

Introduction: Clinical and morphological prognostic factors for PCa are Gleason score, TNM classification lymph node invasion. VEGF is an inducer of angiogenesis, which plays important role in tumor growth metastasis. It was shown that cells express VEGF. Aim: The aim this paper to analyze the immunohistochemical expression prostate adenocarcinoma correlate it with clinical sample patients treated at Hospital Center 'Dr Dragiša Mišović' Belgrade. Material methods: operative material from 20...

Conclusion: Identification of mycobacteria isolated from respiratory specimens over a three-month period by using molecular techniques revealed that the most frequently mycobacterial species in Serbia is M. tuberculosis, while nontuberculous (NTM) local patients are gordonae, xenopi and kansasii. Introduction: Fast accurate identification Mycobacterium tuberculosis complex (MTBC) to level great importance. Highly sensitive specific methods choice for species. The Aim: aim study was recovered...

The plant lemon grass (Aloisia citrodora) was used as material in this work. percentage of dry matter, organic acids and cellulose, determined from the fresh material. Extracts are obtained chopped lemongrass leaves. Extraction done by maceration, Soxhlet ultrasound. content extracted matter extracts determined, vitamin C.
