Additive layer manufacturing is emerging as the next generation in part manufacture. It is being adopted by aerospace, tool making, dental and medical industries to produce and develop new conceptual designs and products due to its speed and flexibility. It has been noted that parts produced using additive layer manufacturing are not to a consistent quality. Variations have been recorded showin...

Batch sorption experiments were conducted with heavy metal solutions in 0.01 M CaCl2 at low equilibrium concentrations of Cu, Pb, Cd, and Cr in 10 different intact soil samples. Metal solid/liquid distribution coefficients Kd were determined from the adsorption isotherms obtained. Their values varied over a range from 57 to 53 000 mL/g. The soils used in the experiment were chosen according to ...

Urban rivers having different catchment areas and properties are investigated in order to infer their heavy metal contribution to the Izmir Inner Bay. The concentrations of Cd, Cr, Cu, Ni, Pb, and Zn in the waters and sediments of these rivers were measured and compared with the limit values given in the Sediment Quality Guidelines and Screening Quick Reference Tables (SQuiRTs). Metal concentra...

Rhizoma Atractylodes macrocephala (AM) has been used in Traditional Chinese Medicine (TCM) for about 2,000 years. In the study, we firstly determined the antioxidant levels of five AM extracts by •OH-scavenging, •O2−-scavenging, Fe2+-chelating, Cu2+-chelating, DPPH·-scavenging, and ABTS+·-scavenging assays. After measurement of the chemical contents in five AM extracts, we quantitatively analyz...

We show the dependence of the Bayesian and the N2-derived oxygen abundances on the N-enrichment history of the star-forming galaxies. We select 531 metal-poor and ∼20,000 metal-rich galaxies from the SDSS database for this study. Their “accurate” O/H abundances are obtained from Te and P method, respectively. The discrepancies of the Bayesian and N2-derived abundances from these two “accurate” ...

Relationships between volume plasmon excitations and mechanical properties of various materials are considered. Based on systematic evaluation of available data, correlations between the volume plasmon energy, Ep, Young's modulus, Ym, bulk modulus, Bm, shear modulus, Gm, and microhardness, Hm, are established. The resulting correlations indicate that plasmon energies potentially can be used to ...

We present measurements of current noise and cross correlations in three-terminal superconductor-normal-metal-superconductor (S-N-S) nanostructures that are potential solid-state entanglers thanks to Andreev reflections at the N-S interfaces. The noise-correlation measurements spanned from the regime where electron-electron interactions are relevant to the regime of incoherent multiple Andreev ...
