In this study, all conditions of the natural dyeing process cotton fabric with antibacterial efficiency, extracted from leaves nettle were optimized using a central composite design. The are: concentration 16.943 g, temperature 50 °C, time 40 min, and color strength obtained at optimum condition was 1.53. Nettle dye is applied to fabrics by Pad-Dry-Cure method for imparting properties textile p...

Within the framework of environmental policies which tend toward new ecological materials, without use petroleum-based objective this work is to develop a composite 100% natural associating fibers European nettles (Urtica Dioica) and PLA (Poly-Lactic Acid). After having determined properties both components composite, methodology was implemented maximize PLA/nettle association. Then, tensile te...

BACKGROUND Species of the scyphozoan family Pelagiidae (e.g., Pelagia noctiluca, Chrysaora quinquecirrha) are well-known for impacting fisheries, aquaculture, and tourism, especially for the painful sting they can inflict on swimmers. However, historical taxonomic uncertainty at the genus (e.g., new genus Mawia) and species levels hinders progress in studying their biology and evolutionary adap...

BACKGROUND Copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) can pose serious threats to environmental health because they tend to bioaccumulate in terrestrial ecosystems. We investigated under field conditions the transfer of these heavy metals in a soil-plant-snail food chain in Banat area, Romania. The main goal of this paper was to assess the Roman snail (Helix pomatia) usefulness in envi...

AIM The objective of this study was to investigate the possible protective role of nettle Urtica dioica (UD) against Hg-induced toxicity. MATERIALS AND METHODS A total of 28 rats were equally divided into four groups: the control, the Hg (0.8 g HgCl2/kg in the diet), the UD (1.5 ml UD/rat by gavage), and the Hg+UD group. HgCl2 was daily dissolved in distilled water and immediately mixed with ...

in this work, electrochemical methods such as tafel polarization and electrochemical impedance spectroscopy (eis) were used to study the inhibition efficiency of nettle leaves hydroalcoholic extract as a green corrosion inhibitor of api 5l carbon steel in 0.5 m h2so4 solution. the results showed that the inhibition efficiency was increased with increasing the concentration of the extract and th...
