Following the discovery of discoloration on some pages of the Atlantic Codex (AC) of Leonardo da Vinci kept in the Biblioteca Ambrosiana in Milan, some investigations have been carried out to verify the presence of microorganisms, such as bacteria and fungi. To verify the presence of microorganisms a noninvasive method of sampling has been used that was efficient and allowed us to highlight the...

Response of near-isogenic sorghum lines, differing at the P locus for plant colour, to grain mould and head smut fungi" (2013). Abstract Leaves and stalks of many sorghum genotypes accumulate dark red or purple pigments upon wounding while some plants, called 'tan,' do not. Grains with unpigmented 'white' pericarps grown on tan plants are more desirable for food. The hypothesis tested was that ...

conclusions totally, our results showed nanosilver caused an increase of at least nine-fold in inhibitory effect of fluconazole. materials and methods we studied effect of fluconazole, nanosilver, and their combination on 20 fluconazole-resistant c. albicans from two centers and one standard sample (atcc10261) by minimal inhibitory concentration (mic) method. background opportunistic fungi caus...

efficiency of pleurotus ostreatus and p. sajor-caju as biocontrol agents of the root knot nematode, meloidogyne javanica, was evaluated in vitro and in greenhouse experiments. population of the nematode were prepared and nematicidal effects of culture filtrates of the fungal specieson second stage juveniles of m. javanica were tested. substrates completely colonized by tested fungi as fungal in...

Abies concolor was introduced to Europe in the 19th century and commonly planted as an ornamental tree. In 2018, after several very warm dry vegetation seasons, which has likely caused abiotic stress trees, a sudden dieback of A. observed city Aranđelovac Serbia. The external symptoms were rapid discoloration needles larger part crown eventually trees. aim this study identify possible agents da...

Timber is a sustainable, economical, completely renewable, CO2-neutral organic material, which requires less energy to process than other construction materials. Wood is also a strong, aesthetically pleasing, and very durable material when properly maintained and used. However, under certain conditions of exposure or use — particularly when it becomes wet — wood may be rapidly decomposed due to...

In this study, we identified and characterized the hydrographic attributes related to the success of recruitment of migratory fishes in the Upper Paraná River floodplain. To achieve our objectives, we analyzed inter-annual variations in the abundance of young-of-the-year (YOY; index of recruitment) of six migratory species and their relations with hydrographic attributes. Recruitment was relate...
