To address the issues of taxonomic delimitation and to select material with desirable traits for horticultural use, a comprehensive study total variability morphological characters two naturally occurring snowdrop species ( Galanthus nivalis L. elwesii Hook.) in central part Balkan Peninsula was conducted. The analyses were performed 16 quantitative aboveground parts 630 plants collected at 21 geographical points territory Republic Serbia. identify trends differentiation, descriptive,...

The paper presents the results on study of possible application Canadian Forest Fire Weather Index and Modified Angstrom in forest fire risk assessments. daily values these indices for period 2005-2015 were related to database. It was found that there is a relatively weak moderate correlation between fires Index. In order improve wildfire assessments (including fires), index modified. modified has significantly greater with actual events consequently much wider southern Serbia. can be great...

Being a natural, ecological and renewable resource, wood is increasingly replacing artificial toxic materials in the manufacture of various types packaging other products; thus, its proper economically justified use has become necessary. The best utilization raw been sought both practice theory, which led to development number non-destructive semi-destructive methods for quality assessments stages exploitation. In this paper, two instruments inspection internal condition standing trees were...

Abstract The paper presents new technology for the tendons of deepwater Tension Leg Platforms (TLPs) based on Carbon Fiber Composites. technology, named 3C-TendonsTM, has been developed by group comprising Freyssinet, Soficar, Bostik Findley, Institut Français du Pétrole and Doris Engineering. solves problems weight fatigue which become critical TLPs in very deep water. are made up multiple numbers subelements each comprises 19 rods, all spoolable transport. For complete tendon, partners...

A total of 179 Douglas fir trees (Pseudotsuga menziesii /Mirb./ Franco) were examined in the municipality Savski Venac, Belgrade, to assess condition this non-native species Serbia and its adaptability urban environments. Tree measurements (trunk diameter, tree height crown diameter) taken, rated for vitality decorativeness. The found be a very good condition, with 89.05% them showing no visible signs disease. average rating was 3.94, decorativeness 3.57. results some physical exceeded...

ISHS I International Symposium on Botanical Gardens and Landscapes Effect of substrate type cultivation position growth safety to consume the edible medicinal species Crithmum maritimum L., in an extensive urban green roof Athens (Greece)

Based on literature sources, the stress wave and ultrasound methods tools designed for evaluation of effects decay wood are discussed in this paper. To make a review results obtained numerous studies, analytic-synthetic method was used data conducted. The revealed high correlations between measured properties actual quality. A number studies show that acoustic velocities correlate well to density other properties. Changes velocity variations caused by have also been detected successfully...

The wood of northern red oak (Quercus rubra L.), considered to be a very high-quality material for processing in the industry, has not been tested Serbia so far. To date, there are only small areas under Serbia, but significant stands this species vicinity Belgrade. In paper, basic physical and mechanical properties were tested. examined 57 years old tree was located forest Lipovica, near cut down two logs taken laboratory analysis. results show that do differ significantly from native -...

Project of forests condition monitoring (ICP Forests) operates as an international European project in which, on grid ICP sample plots (bioindication points) has been monitored annually continuity, including recording data defoliation with evidencing any damage to the trees. The main goal program is a permanent, representative surfaces, arranged systematic distributed territory Europe. This paper analyzes part results forest conditions Republic Serbia, period 2012-2016. assessment performed...

In this paper, transversal stress wave velocity was measured in 30 trees of Serbian spruce (Picea omorika /Pančić/ Purk.) using a 2D sonic tomograph. Tomograms were analyzed and speed loss average for calculated. Since there is no reference value species, research the Norway abies /L./ H. Karst.) used comparison. The relative difference between referent indicates amount decay two sensors. largest number cross-sections had up to 10%, but also with more than 50% direction. This result shows...

ISHS IV International Symposium on Horticulture in Europe - SHE2021 Effect of substrate type and cultivation site the urban fabric growth safety to consume edible medicinal species Origanum dictamnus

Chemical properties of gypsy moth larvae excrement were analysed with an objective to ascertain their possible impact on forest ecosystem nutrient cycling. The content nutrition macro-elements in excrements was determined and compared the oak leaves. nitrogen mineral forms group-fractional composition humus determined. It established that during total defoliation period there had been no loss ecosystem. dropped incorporated are such new leave formation after provide a sufficient amount...

In this paper authors research consumer attitudes about the purchase and consumption of organic food in Republic Serbia. The aim is to identify main factors that influence on demand for agricultural products.Three quarters respondents are not familiar with law food.Requires a significant education direction order better inform increase demand. largest proportion (40%) have confidence domestic products, which good basis supply market. number interviewed persons buy products at markets (40%),...

Forty-two trees of northern red oak (Quercus rubra L.) were examined in the area municipality Savski Venac, Belgrade, to assess condition this allochthonous species Serbia and its adaptability urban environments. Physical measurements taken ratings vitality decorativeness given. The analyzed are very good based on their health status (80.95% without visible indication disease) mean values for (4.45) (3.88). obtained some physical greater than those stated literature, suggesting that has...

Wood density and fibre length are two wood properties that important in determining the quality of for commercial use. The red oak has not been studied to same extent as other species. aim this paper is explore anatomical variation wood, valuable information researchers fields. Samples were taken a 60-year-old stand south part Belgrade on site Stepin Lug. Along radius, disc samples 20 x mm cut from sapwood, mature juvenile wood. Ovendry measured pith bark. According obtained data, average...

In this paper, Soil Protection Coefficient (Xa) was quantified through the approach of high resolution multispectral orthomosaic segmentation and classification. The presented in example ski lane center Kopaonik. data collection performed application Unmanned Aerial System equipped with 5band sensor RGB sensor.
