Allometric biomass models for european beech and silver fir: Testing approaches to minimize the demand for site‐specific biomass observations
(2020)In this paper, site‐specific allometric biomass models were developed for European beech (Fagus sylvatica L.) and silver fir (Abies alba Mill.) to estimate the aboveground biomass in Șinca virgin forest, Romania. Several ... -
Bioethanol steam reforming over Pt and Ag in an electrochemical CSTR reactor
(2005)The environmental problems caused by the intensive use of fossil fuels-as well as their limited availability- are increasingly demanding a more rational use of our energy resources. Among the various fuels which can be ... -
Chemical characterisation, antibacterial activity, and (nano)silver transformation of commercial personal care products exposed to household greywater
(2019)The objective of this study was to test the original speciation of silver (Ag) in eight different commercially available personal care products and investigate the chemical transformation of Ag during exposure to two types ... -
Finite elements analysis of cylindrical copper shelled SLA electrodes
(2010)A cylindrical copper shelled SLA electrode was modelled and analysed using the finite element method. The thickness of the silver paint is assumed to be uniform and constant around the SLA epoxy core with a value of 15 ... -
Hazardous enrichment of toxic elements in soils and olives in the urban zone of Lavrio, Greece, a legacy, millennia-old silver/lead mining area and related health risk assessment
(2022)Lavrio is a Greek town with several abandoned Ag/Pb mines. In this study, 19 potentially toxic elements (PTEs) were measured in soil, weeds, and olives. Levels of seven of the studied PTEs in soil were highly elevated: Zn ... -
The informational content of unconventional monetary policy on precious metal markets
(2018)This paper investigates the informational content of unconventional monetary policies and its effect on commodity markets, adopting a nonlinear approach for modeling volatility. The main question addressed is how the Bank ... -
Investigation of the reaction of ethanol-steam mixtures in a YSZ electrochemical reactor operated in a fuel cell mode
(2006)In the present investigation ethanol-water mixtures were directly fed to a yttria stabilized zirconia (YSZ) electrochemical reactor operated in a fuel cell mode and the preliminary results are presented and discussed. ... -
Medical-Grade Polyamide 12 Nanocomposite Materials for Enhanced Mechanical and Antibacterial Performance in 3D Printing Applications
(2022)During the COVID-19 pandemic, wide use of 3D printing technologies has been enabled. Fused filament fabrication (FFF) is the most widely used technique in 3D printing communities worldwide for the fabrication of medical ... -
Silver nanoparticles alter cell adhesion and proliferation of sheep primary mesothelial cells
(2018)Background: Human exposure to engineered nanoparticles has been linked to pleural effusion, inflammation and fibrosis. Silver nanoparticles (AgNPs) are widely used in medical and domestic products, increasing the risk of ... -
Silver nanoparticles alter the permeability of sheep pleura and of sheep and human pleural mesothelial cell monolayers
(2017)Nanoparticles have been implicated in the development of pleural effusions in exposed factory workers while in experimental animal studies it has been shown that they induce inflammation, fibrosis and carcinogenesis in the ... -
Silver Toxicity Thresholds for Multiple Soil Microbial Biomarkers
(2018)Material flow analysis shows that soil is a key repository for silver (Ag) from (nano)silver-functionalized consumer products, but the potential effects of Ag toxicity, via Ag+ release, on soil microbial communities and ... -
Strategic noise map & action plans for the agglomeration M6 "Piraeus" (2002/49/EC Directive)
(2016)This paper presents the Strategic Noise Mapping & Action Plans for the agglomeration of "Piraeus" (implementation of 2002/49/EC Directive). The studied area is complicated, covers 6 municipalities: Piraeus, Chaidari, Ag. ... -
Wet chemical silver treatment of endotracheal tubes to produce antibacterial surfaces
(2007)Mechanically ventilated patients in hospitals are subjected to an increased risk of acquiring nosocomial pneumonia that sometimes has a lethal outcome. One way to minimize the risk could be to make the surfaces on endotracheal ...
