Measuring the dynamic relationship between banking and industries with systemic importance has attracted much attention after the recent financial crisis. This paper examines the dynamic conditional correlations and volatility spillover using three popular multivariate GARCH models in the twelve-year period (from the beginning of 2005 to the beginning of 2016) among the fourteen systemically im...

Depending on such factors as the intensity and duration of the exposure, and the genetic diversity and connectedness of the starting population, exposure to elevated metal concentrations can result in population level alterations such as demographic bottlenecks or metal-induced selection. These processes can be revealed using a population genetic approach, and have important implications with r...

Effects were studied of 200 ppm silver and copper nano-suspensions, with size range from 20 to 80 nm, on the hardness of particleboards produced at an industrial scale at the Iran-Choob Factory, Iran. Metal nano-suspensions were added to the mat at two levels of 100 and 150 milli-liters/kg dry weight wood particles, and the results were compared with those of the control panels. Results showed ...

The metal (Cd, Cu, Pb, Zn and Ca) concentrations in the tissues, ingesta (crop contents) and egesta (faeces) were investigated in two physiologically contrasting earthworm species (Lumbricus rubellus and Aporrectodea caliginosa) inhabiting soils exhibiting various levels of heavy metal contamination. In addition, a complementary soil layering experiment, conducted under laboratory conditions, w...

BACKGROUND The goal of our study was to evaluate the effects of different medicinal herbs rich in polyphenol (Lemon balm, Sage, St. John's wort and Small-flowered Willowherb) used as dietary supplements on bioaccumulation of some essential metals (Fe, Mn, Zn and Cu) in different chicken meats (liver, legs and breast). RESULTS In different type of chicken meats (liver, legs and breast) from ch...

To investigate the mechanisms involved in metal stress in wild fish, yellow perch (Perca flavescens) were collected in eight lakes of the Rouyn-Noranda and Sudbury regions (Canada). Due to mining and smelting activities, these two regions indeed present a broad contamination gradient in metal concentrations (Cd, Cu, Zn and Ni; water, sediment and prey) and offer a unique research opportunity to...

Due to its outstanding properties and wide range of applications, high-purity ultra-high-purity aluminum represents a strategic material for meeting the future challenges 21st century. The purification towards higher purity levels is usually performed via combination three-layer electrolytic refining fractional crystallization using zone-melting processes. New methods processes are being resear...

We study the influence of Coulomb correlations on spectral and magnetic properties fcc cobalt using a combination density functional theory dynamical mean-field theory. The computed uniform local susceptibilities obey Curie-Weiss law, which, as we demonstrate, occurs due to partial formation moments. find that lifetime these moments in is significantly less than bcc iron, suggesting more itiner...

We use the radiative potential method to perform a detailed study of quantum electrodynamics (QED) corrections electric dipole (E1) transition amplitudes in heavy alkali-metal atoms Rb, Cs, Fr, and alkali-metal-like ions Sr+, Ba+, Ra+. The validity is checked by comparing with results rigorous QED simple atomic potentials. effects core relaxation, polarization E1 field, valence-core correlation...
