Lavandula sp. essential oil and hydrolate are commercially valuable in various industry branches with the potential for wide-ranging applications. This study aimed to evaluate quality of these products obtained from L. x intermedia cv. ‘Budrovka’ first time cultivated on Fruška Gora Mt. (Serbia) during three successive seasons (2019, 2020, 2021). Essential extraction was by steam distillation, composition influence weather conditions were also assessed, using flowering tops. The oils...

Road traffic accidents are a significant public health issue, accounting for almost 1.3 million deaths worldwide annually, with millions more experiencing non-fatal injuries. A variety of subjective and objective factors contribute to the occurrence accidents, making it difficult predict prevent them on new road sections. Artificial neural networks (ANN) have demonstrated their effectiveness in predicting using limited data sets. This study presents two ANN models common roads Republic...

This study investigates the applicability of Peleg model to osmotic dehydration various sweet potato variety samples in sugar beet molasses, addressing a notable gap existing literature. The was performed using an 80% molasses solution at temperatures 20 °C, 35 and 50 °C for periods 1, 3, 5 h. sample-to-solution ratio 1:5. objectives encompassed evaluating equation’s suitability modeling mass transfer during determining equilibrium water solid contents temperatures. With its modified...

This study investigated the impact of climate conditions on quality essential oils extracted from Apiaceae fruits, specifically coriander (Coriandrum sativum var. microcarpum), aniseed (Pimpinella anisum), and annual caraway (Carum carvi annuum) grown at three distinct locations in Serbia over consecutive years. Field experiments were conducted, using a Clevenger-type apparatus followed by gas chromatographic–mass spectrometric analysis for compound identification. Weather during vegetation...

The present study investigated the effect of incorporating 10, 20, and 30% apple powder obtained by freeze-drying, produced with osmotic pre-treatment in sugar beet molasses solution, into muffins. was freeze-dried introduced as a whole spelt wheat flour replacement products were for their chemical composition technological properties, subjected to sensory analysis well consumer acceptance test. Increasing substitution level from 0 lowered protein, starch, fat content, while moisture sugar,...

Unlike other studies that only determined the chemical composition of essential oils depending on their geographic origin, this research investigated effect weather conditions (temperature, precipitation, and insolation) Nepeta nuda L. oil. The collection wild-growing N. was carried out during three successive years, 2019, 2020, 2021 at Rtanj Mountain (Serbia) same date (July 7th). Essential oil extraction from plant performed by hydro-distillation. After gas chromatographic-mass...

Garden angelica (Angelica archangelica L.), native to the northern temperate region, is widespread in Europe and Asia. Since middle ages, it has been used for healing as a vegetable traditional dishes. In modern era, proven that A. complex chemical composition. The main derivatives contribute plant’s biological activities are essential oil coumarins. this review, focus on cross-analysis of taxonomy archangelica, its distribution different regions, with presentation richness biochemical...

Our previous research has proven that the immortelle (Helichrysum italicum) essential oil (EO) grown in Serbia possesses respectable biological potential and desirable composition of volatile compounds with for a wide range applications food, cosmetics, pharmaceutical industries. Within this study, impact seasonal variations (temperature, precipitation, insolation) during three successive years (2017, 2018, 2019), on profile γ-curcumene + ar-curcumene chemotype was determined. Steam...

Predicting yield is essential for producers, stakeholders and international interchange demand. The majority of the divergence in oil content associated with environmental aspects, including weather conditions, soil variety cultivation techniques. Therefore, aniseed production was examined this study. categorical input variables artificial neural network modelling were growing year (two successive years), locality (three different locations Vojvodina Province, Serbia) fertilization type (six...

The main idea of the present study was to investigate impact ongoing world crisis on socio-economic issues in Serbia concerning building materials usage and purchase. This research fills gaps literature contributes comprehension how has affected salaries, market pricing, consumption sector. data are gathered through a questionnaire analyzed using statistical methodology (frequencies, descriptive statistics, Spearman’s correlations). Most former studies investigated surveys conducted...

The technical analysis of a hybrid wind-photovoltaic energy system with hydrogen gas storage was studied. market for the distributed power generation based on renewable is increasing, particularly standalone mini-grid applications. main design components PV/Wind are PV panels, wind turbine and an alkaline electrolyzer tank. transient simulation program TRNSYS 16. study realized using meteorological data Typical Metrological Year (TMY) region Novi Sad, Belgrade cities Kopaonik national park...

This paper presents CFD (Computational Fluid Dynamics) approach to prediction of the heat transfer coefficient for nucleate pool boiling under high fluxes. Three-dimensional numerical simulations atmospheric saturated are performed. Mathematical modelling requires a treatment vapor-liquid two-phase mixture on macro level, as well micro such bubble growth and departure from heating surface. Two-phase flow is modelled by two-fluid model, which consists mass, momentum energy conservation...
