Stavovi studenata o efikasnosti nastave engleskog jezika struke
No full textU savremenom visokom obrazovanju, posebno na tehničkim fakultetima,
engleski jezik struke (ESP) ima ključnu ulogu u pripremi studenata za profesionalnu
i akademsku komunikaciju. Cilj ovog istraživanja je da ispita kako studenti
biotehničkih fakulteta (Šumarski fakultet i Poljoprivredni fakultet
Univerziteta u Beogradu) doživljavaju različite aspekte ESP nastave. Upitnik je
koncipiran tako da obuhvata šest aspekata ESP nastave: funkcionalnu upotrebu
jezika, nastavu zasnovanu na zadacima, povratnu informaciju i ispravke, gramatiku i
tačnost, tehnologije u učenju i opšte utiske o kursu. Studenti su odgovarali na 30
tvrdnji koristeći petostepenu Likertovu skalu, pri čemu su se izjašnjavali o
sopstvenim iskustvima i stavovima. Istraživanjem je utvrđeno u kojoj meri studenti
imaju sklonost ka praktično orijentisanim aktivnostima, kao što su prezentacije,
timski rad i rešavanje zadataka iz struke, u poređenju sa tradicionalnim gramatičkim
vežbama. Jedan od predmeta istraživanja je i vrednovanje povratne informacije
dobijene od nastavnika ali i kolega, jer ona direktno utiče na njihovo samopouzdanje i
napredak u komunikaciji. S obzirom na to da digitalni alati, aplikacije i autentični
materijali nastavu čine dinamičnijom i povezuju je sa realnim profesionalnim
okruženjem ispitani su stavovi studenata o njihovoj upotrebi u ESP nastavi. Dobijeni
nalazi doprinose boljem razumevanju načina na koje studenti doživljavaju ESP nastavu
i pružaju smernice za unapređenje nastavnih programa u skladu sa savremenim
potrebama obrazovanja i očekivanjima studenata
First Report of Bacteria Associated With Bleeding Cankers on Oak Trees in Serbia
No full textThe aim of this study was to confirm the presence of bacteria that are partly responsible for the oak dieback phenomenon, known as Acute Oak Decline, in Serbia. Seventeen symptomatic oak trees (both Quercus robur and Quercus cerris) were sampled in April 2024 and analysed using multiplex real-time PCR. Brenneria goodwinii was detected in one tree from Morović, whereas Gibbsiella quercinecans was found in two trees from Morović and Progar. This is the first report of these bacteria in Serbia, despite bioclimatic models predicting a low likelihood of their presence in the Balkans. Our results indicate the presence of oak dieback bacteria in areas where they have not yet been reported, highlighting the need for increased research and awareness of bacterial diseases in forest trees
Impact of Microplastics on Forest Soil Properties in Pollution Hotspots in Alluvial Plains of Large Rivers (Morava, Sava, and Danube) of Serbia
No full textPlastic pollution has become a major environmental problem, while the products of its degradation, microplastics (MPs), appear everywhere on Earth. Data on MPs in agricultural soils have appeared lately, but a significant knowledge gap exists regarding forest soils. In Serbia, municipal waste is often dumped in forests, creating environmental problems that have not been documented. To explore the impact of waste dumping and MPsonforest fluvisols, we evaluated MPs from topsoils of three waste dumps and adequate visibly plastic non-contaminated forest sites located in alluviums of the largest rivers in Serbia. For assessing the influence of environmental factors on soil MPs, samples were taken in three forest vegetational seasons, in two years. The impact of MPs on soil structure, chemistry, and microbial respiration (MR) was examined. Undisturbed soil columns from uncontaminated sites with added known MP particles were used to estimate the dynamicof MPtransfer through the topsoil. Large aggregate formation, soil coarse sand content, specific mass, porosity, and available P, but not MR were affected by contamination. Seasonal and annual environmental changes significantly influenced the behavior of MPs in forest luvisols. MPs effectively penetrated the deeper layers of soil columns within 3 months, with strong accumulation in the 0–10 cm layer.This article belongs to the Special Issue Influence of Environmental Changes on Forest Soil Quality and HealthSupplementary data on this link: [https://rivec.institut-palanka.rs/handle/123456789/1057
Revisiting the Contested Case of Belgrade Waterfront Transformation: From Unethical Urban Governance to Landscape Degradation
No full textThis paper examines two large urban projects within a defined theoretical and
methodological framework. Firstly, we analyse how the city administration in Belgrade,
in post-socialist Serbia, managed the initial steps of the transformation of a part of the old
town into the new large-scale development, the Belgrade Waterfront (BW), on the right bank
of the Sava River. The contested outcome of the land transformation process contributes
to a recognition of the unethical decision-making and performance of the responsible city
authorities. Secondly, the postwar planning and construction of New Belgrade, in particular
its Central Zone, is critically examined from the aspect of radical urban landscape transformation and its impact on society. Through a critical examination of the spatial development
of the socialist period, we aim to identify emancipatory architectural and urban practises
that could be an alternative to contemporary spatial production and that might provide
a notion of key strategies for (re)establishing corresponding forms of socio-spatial justice.
The two aforementioned research subjects are examined using different research questions,
methodological tools, and different theoretical frameworks, which overlap, merge, and
combine in the part of the study where the obtained results are discussed
Monitoring land use change in Vojvodina using the collect earth tool
No full textUsing visual photointerpretation through the Collect Earth application, spatial and temporal
changes in land use (land categories) were analysed in the territory of the Autonomous Province
(AP) of Vojvodina during the period 2000–2019. A total of 86.328 plots were interpreted,
systematically distributed within a 1x1 km cluster grid spanning seven administrative districts
of Vojvodina. Land use changes were monitored across 6 land categories: agricultural land (C),
forests (F), grasslands (G), other land (O), urban land (S), and water surfaces (W), in four
temporal intervals: 2000–2005, 2005–2010, 2010–2015, and 2015–2019. Over the course of 19
years, 41 plots with land category changes were recorded. In the North Bačka and North Banat
districts, no changes were registered in any plot. The Srem district stood out as the only region
with more dynamic and structurally diverse spatial changes. In this region, 37 plots with land
use changes were recorded and distributed across three-time intervals. The most frequent types
of change were C → S (9 plots) and C → F (4 plots), while the number of registered plots with
transitions between other land categories ranged from 1 to 3—predominantly a single plot.
From the perspective of the importance forests hold today, all changes except those of type C
→ F can be qualified as positive. Changes in the opposite direction, including F → C, have a
negative impact on forest resources and biodiversity. It can be concluded that land use changes
during the observed period were minimal, arising in accordance with land management
practices in particular categories of land in Vojvodina, and proceeded along established
patterns, which is of great importance for long-term decision-making in the field of resource
management and conservation
Secondary flowering and fruiting of laburnum anagyroides medik. and their importance in urban landscape design
No full textWoody plants and their phenology represent a significant element in the design of green
spaces, as they perform various crucial ecosystem services. This study analysed the abundance of
flowering, morphometric characteristics of inflorescences, flowers and fruits, as well as phenological
patterns of secondary flowering of the Common laburnum in the Arboretum of the Faculty of Forestry
in Belgrade, recorded in 2023 and 2024. The research highlighted the significant visual impact and
the unusually long duration of repeated flowering, which is atypical for this species at the end of
autumn and the beginning of winter. Altered climatic parameters, especially air temperatures, as well
as the genotype of the analysed individuals, triggered repeated flowering and fruiting after the end
of the growing season. Due to its ornamental value, resilience, and adaptability, Common laburnum
is recommended for widespread use in urban design, particularly given its wide range of ecological,
landscape and social benefit
Punica granatum L. In garden design in Serbia
No full textDue to altered climatic conditions, many thermophilic taxa—Mediterranean floral
elements—have been introduced into Serbia, among them the utilitarian and ornamental species
Punica granatum L. Accordingly, this study investigates Pomegranate individuals in two private
gardens in Serbia, located in Belgrade and Zagorica. The research analysed the dendrometric
characteristics of the plants, the morphological traits of the fruits and the phenology of flowering and
fruiting during the period 2022–2024. Based on data collected over three consecutive years,
descriptive statistics were used to determine fruit yield and fruit mass. An important finding is that
the key elements of the fruiting phenological pattern were identical to those observed in plants grown
under Mediterranean climate conditions. The study confirmed the good vitality, adaptability, and
sustainability of Pomegranate, which opens up the possibility of incorporating it as a fruit-bearing
species in garden design under the altered temperate continental climate conditions in Serbia
Impact of natural degradation on the phenolic profile of pedunculate oak stump (Quercus robur L.): Insights from HPTLC and spectrophotometric assays
No full textThe pedunculate oak (Quercus robur L.) is rich in extractives, especially in its heartwood, stumps, and bark, making it valuable to bio-based industries. Due to this reason and the increasing demand for efficient wood utilization, this study investigated the extractives of stumps remaining after freshly cut trees and Q. robur trees cut two years prior. During these two years, the stumps were exposed to various weather conditions (precipitation, UV radiation, and others) and the action of fungi, bacteria, and other pathogenic organisms. These factors contributed to the natural degradation of the wood and the disruption of the original chemical structure of the stumps. Water extracts from the xylem and bark of freshly cut and biodegraded Q. robur stumps were analyzed for total phenols, activity against H2 O2 , and free radical scavenging activity. Total phenol content was higher in degrading Q. robur stumps, with 71.70 and 59.17 mg gallic acid equivalents/g dry wood in bark and xylem, respectively. Degrading Q. robur stump bark and xylem showed higher antioxidant activity, with IC50 values against H2 O2 of 682.39 µg/mL and 923.90 µg/mL, and free radical scavenging activity of 91.97% and 83.98%, respectively. High-performance thin-layer chromatography fingerprinting profile of xylem and bark extracts revealed different chemical profiles, while the HPTLCDPPH scavenging assay evaluated antioxidant activity in extracts. This research showed that extracts from the bark and xylem of the degrading stump are stronger radical scavengers and have a richer phenolic profile than extracts from a freshly cut stump. Degrading Q. robur stumps may represent a valuable source of polyphenols
Uvoz odabranih drvnih goriva u zemlje EU-27 i promjene u opskrbi
No full textThe paper presents the results of the analysis of the supply of wood pellets, wood chips, wood briquettes, sawdust and wood waste and scrap on the EU market from non-EU countries in the period 2010-2023. The aim of the study was to identify the most important non-EU countries for the supply of selected wood fuels to the EU market and the volume of imports. In addition, the value of imports of selected fuels from non-EU countries and from individual non-EU countries that are the largest suppliers to the EU market were analyzed. The study pays particular attention to the period 2022-2023, during which the EU initially reduced and then suspended imports of wood fuels from Russia and Belarus. The EU met part of its energy needs by importing wood fuels from non-EU countries during the period under review. The analyses carried out provided an insight into the EU’s energy dependence on the import of selected wood fuels from non-EU countries. Regression models were used in this paper to determine the impact of EU imports of wood pellets from non-EU countries on the consumption of wood pellets in the EU
