Adjusting the parameters of metal oxide gapless surge arresters' equivalent circuits using the harmony search method
(2017)The appropriate circuit modeling of metal oxide gapless surge arresters is critical for insulation coordination studies. Metal oxide arresters present a dynamic behavior for fast front surges; namely, their residual voltage ... -
The combined and single effect of salinity and copper stress on growth and quality of Mentha spicata plants
(2019)Copper is essential for plant growth, but in excess may cause adverse effects on plant physiology. Harmful effects are also caused by plant exposure to salinity (NaCl) due to the excessive use of fertilizers, soil degradation ... -
Cost Effective Synthesis of Graphene Nanomaterials for Non-Enzymatic Electrochemical Sensors for Glucose: A Comprehensive Review
(2022)The high conductivity of graphene material (or its derivatives) and its very large surface area enhance the direct electron transfer, improving non-enzymatic electrochemical sensors sensitivity and its other characteristics. ... -
Coupled numerical simulation of low-cycle fatigue damage in metal components
(2021)A coupled cyclic plasticity-damage model is implemented for simulating low-cycle fatigue in metal components. Constitutive relations account for J2-flow theory with nonlinear kinematic/isotropic hardening, coupled with ... -
Environmental geochemical research for the levels and the sources of toxic metals in the agricultural soils of dimitraeleftherion and platycampos region, Thessaly, Greece
(2007)The contents of eleven elements (Cu, Pb, Zn, Ni, Co, Mn, Fe, As, V, Cr and Mg) have been assayed in the agricultural soils of Dimitra-Eleftherion and Platycampos region (Thessaly, Greece). One hundred twenty two top soil ... -
Evidence of Au – Hg gilding process in post byzantine ecclesiastical silverwares (Chalices) of eastern Thessaly by PXRF
(2020)Silver and gold alloys have been widely applied in the making of precious objects during the byzantine and post byzantine eras. A major category is the “ecclesiastical silver”, which was used in the celebration of the ... -
Fatigue failure investigation of pre-corroded and laser-welded Al-Cu-Mg-Ag Alloy with different temper condition
(2010)The fatigue failure mechanisms of pre-corroded, laser beam welded Al-Cu-Mg-Ag alloy in different temper conditions (T3,T8) have been investigated. Aging influences the corrosion behavior of laser welds. In the T3 temper, ... -
Fatigue performance of pre-corroded 6xxx aluminum alloy laser beam welds with dissimilar heat treatment
(2014)The role of existing corrosion damage on the fatigue performance of 6156 AA laser beam welds in T3 state, with additional post weld heat treatment T8, has been assessed. The welds were subjected to salt fog environment for ... -
A framework for formulating and implementing non-associative plasticity models for shell buckling computations
(2022)In modelling the behavior of thick-walled metal shells under compressive loads, the use of J2 flow theory can lead to unrealistic buckling estimates, while alternative ‘corner’ models, despite offering good predictions, ... -
Green remediation of toxic metals contaminated mining soil using bacterial consortium and Brassica juncea
(2021)Microorganism-assisted phytoremediation is being developed as an efficient green approach for management of toxic metals contaminated soils and mitigating the potential human health risk. The capability of plant growth ... -
Highly effective oxygen reduction reaction electrocatalysis: Nitrogen-doped hierarchically mesoporous carbon derived from interpenetrated nonporous metal-organic frameworks
(2017)Nitrogen-doped carbon materials with hierarchically mesoporous structure are synthesized in the present work via the pyrolysis of an interpenetrated non-porous metal-organic framework (MOF), viz. [Zn2(TPT)(BDC)2]·H2O ... -
Metal stack and partitioning exploration for monolithic 3D ICs
(2020)In this work, we investigate the effect of metal stack and tier 3D IC partitioning methodologies on the Quality of Results (QoR) of monolithic 3D circuits compared to their 2D counterparts. Two interconnect options are ... -
Metal(loid) and isotopic tracing of Pb in soils, road and house dusts from the industrial area of Volos (central Greece)
(2020)This study examines the metal(loid) contents (As, Cd, Cr, Cu, Mn, Ni, Pb, Sb, Tl and Zn) and Pb isotopes in different environmental compartments (soil, road dust, house dust) from the industrial vicinity of Volos, central ... -
Protrusio of a ceramic femoral head through the acetabular metallic shell, extensive metallosis and 'bubble sign'
(2009)A 24-year-old patient with a history of juvenile rheumatoid arthritis underwent a primary cementless left total hip arthroplasty (THA). The original THA consisted of an Optifix 54 cup with a 3-mm thick polyethylene liner, ... -
Pt/CN-doped electrocatalysts: Superior electrocatalytic activity for methanol oxidation reaction and mechanistic insight into interfacial enhancement
(2017)Nitrogen-doped ordered mesoporous carbon (NOMC) is studied as the support to synthesize a Pt/CN-doped catalyst for methanol oxidation reaction (MOR). The effects of carbon dimension and metal loading are investigated by ... -
A second gradient elasto-plastic model for fatigue of small-scale metal components
(2010)Purpose - As the dimensions of structures are scaled down to the micro- and nano-domains, the mechanical behavior becomes size dependent and thus, the classical elasticity solutions cannot be expected to hold. In particular, ... -
Sorption of Cu and Zn in low organic matter-soils as influenced by soil properties and by the degree of soil weathering
(2015)Copper and Zn sorption and desorption, among other factors, depend on soil pH, but in soils with different degree of weathering the role of other soil properties (. e.g., oxides content and the level of their crystallinity) ... -
