Nanotechnology has a great but largely unexplored potential in this field, providing new tools and methods to achieve higher consolidation and protection efficiency, mainly due to the ability of nanoparticles to inhibit the growth and metabolic activity of different biodeteriorating agents, including fungi. The purpose of the present study was to report for the first time on the efficiency of MgB2materials, mainly prized for their practical superconducting properties, against a large collection of filamentous fungal strains recently isolated from biodeteriorated wooden and stone heritage objects. Four types of MgB2powders, with a crystallite size of 42–113 nm, were tested by qualitative (on 149 strains) and quantitative (on 87 strains) assays. The cytotoxicity was evaluat...

It provides basic information that can be used in estimating their ecological preferences but also the success of eradication strategies. Mapping of vegetation is a time consuming task and especially problematic for annuals whose population distribution and abundance show year–to-year variability. Alternatives to this bottom-up approach are therefore highly needed when producing vegetation maps and inventories. The paper examines the potential of using the top-down approach for producing pollen source inventories, which employs spatial variations in annual airborne pollen counts to indicate the abundance of invasive species. The ragweed pollen source inventory over Vojvodina is presented here as an example. The degree in which the performance of the method is affected by spatial resolution is investigated.

The field is located in Didactic Station of Banat University of Agricultural Sciences and Veterinary Medicine „King Michael I of Romania” from Timișoara, Romania. The investigated species was Triticum aestivum ssp. vulgare, Ciprian cv. Wheat was fertilized during spring with a liquid complex which contain zinc. This microelement has diverse biological roles in plants, being involved in enzymatically driven metabolism and pollen tube development. Soils and plants zinc deficiency is a global problem. Zinc deficiency can also be observed in humans, particularly in developing countries. Thus, increasing zinc content in plants, especially in widely consumed worldwide cereals became of interest. In this research zinc was sprayed to leaves of wheat plants in five experimental doses. Intact leaves were analyzed in the laboratory and the values of some physiological parameters were determined. The studied indices wer...

The investigation of Ambrosia pollen concentrations was carried out from 2000 to 2010 by means of the volumetric method. Ambrosia pollen concentrations had increasing trend over study period. The results of cluster analysis show that two main groups were identified: group A, with lower SPI (2000, 2001, 2002, 2003, 2004, 2007) and group B, with much higher SPI (2006, 2008, 2009, 2010). The statistical correlation between pollen concentrations and meteorological factors was determined by Pearson’s test. The relationships between Ambrosia pollen concentrations and meteorological parameters, were further assessed using multiple linear regression techniques. The pollen emissions are affected by meteorological factors in the main pollen season. Our results suggest that the abundance of Ambrosia artemisiifolia in wes...

In this study, physiological traits were examined in plants growing outdoors, in the proximity of a road. All material was collected from robust, well-grown plants. All measurements were performed during the generative phase. Here, the evaluations of some gravimetric parameters (fresh weight, turgid weight, dry weight, water content, ash content) and physiological parameters (initial water content, mineral content, organic content, organic content/mineral content ratio, succulence, mineral deposition in tissues, tissues density, leaf relative water content, specific leaf area) were calculated for <em>Taraxacum officinale</em> from urban unmanaged areas, across the different seasons (winter, spring, summer, fall). One-way analysis of variance (ANOVA) was used to compare these traits in leaves, scapes, and roots. Initial water content and relative water content are good indicators of water s...

The airborne spore sampling was carried out by employing volumetric sampling. A total of nine meteorological parameters were selected for this investigation. During 2008–2010, it was found the same pattern of behaviour in the atmosphere for selected spore types (Alternaria, Cladosporium, Pithomyces, Epicoccum and Torula). The spores occurred in the air throughout the whole year, but maximum concentrations were reached in summer. Cladosporium and Alternaria peak levels were observed in June. Epicoccum peak value was found in September. The relationships between airborne spore concentrations and environmental factors were assessed using the analysis of Spearman’s rank correlations and multiple linear regressions. Spearman’s rank correlation analysis revealed that maximum, minimum and mean temperature, and number of sunshine hours were strongly (p < 0.01) and directly proportional to the concentration of all analysed fungal spores. Negative and significant correlations were with daily mean relative humidity. The variance explained percentage by regression analyses varied between 30.6 and 39.6 % for Alternaria and Cladosporium airborne spores. Statistical methods used in this study are complementary and confirmed stable dependence of Alternaria and Cladosporium spore concentrations on meteorological factors. The climate change parameters either increased temperatures, changed precipitation regimes or a combination of both affected allergenic fungal spore concentrations in western Romania. This study demonstrates the need for investigations throughout the year, from month to month, regarding the correct interpretation of airborne spore relationships with meteorological parameters.
