The role of the substrate on the morphology of nanometer size clusters fabricated by buffer layer assisted growth (BLAG) was studied using scanning tunneling microscopy. Clusters of Fe and Co were deposited on Ag(111), Cu(100), Rh(111), and Pt(111) surfaces using identical BLAG parameters, which are temperature, as well as metal and buffer layer coverage. Semi-hemispherical clusters are found o...

Concentrations of Pb, Cd, Cu, Zn, Cr and Ni in soybean (Glycine max L.) grown near the Dabaoshan Mine were investigated, and their potential risk to the health of inhabitants was estimated. In the Fandong (FD) and Zhongxin (ZX) villages, which are near the Dabaoshan mineral deposit, concentrations of Pb (0.34 mg kg−1 for FD), Cd (0.23 mg kg−1 for ZX) and Cr (1.14 and 1.75 mg kg−1 for FD and ZX,...

In 1975, Social Security beneficiaries were given the option of having their monthly benefit payments sent directly to their banks through an electronic funds transfer system. Since then, beneficiaries have been enrolling in this program in rapidly increasing numbers. At the end of 1976, fewer than 5 million beneficiaries--14 percent of the total--were enrolled in the program. By the end of 198...

Chaperone-usher (CU) fimbriae are adhesive surface organelles common to many Gram-negative bacteria. Escherichia coli genomes contain a large variety of characterised and putative CU fimbrial operons, however, the classification and annotation of individual loci remains problematic. Here we describe a classification model based on usher phylogeny and genomic locus position to categorise the CU ...

In this work, the concentrations of the potentially toxic elements in stream sediments in SE Nigeria were assessed for pollution monitoring in mining, quarrying, and farming areas. The levels of iron, molybdenum, vanadium, copper, lead, zinc, nickel, cobalt, manganese, chromium, barium, and beryllium were determined. The concentrations of the elements were in the order of Fe > Ba > Mn > Cr > Zn...

Mineral resource classification is an important step in mineral exploration and mining engineering. In this study, copper molybdenum resources were classified using a combination of the Turning Bands Simulation (TBSIM) Concentration–Volume (C–V) fractal model based on Conditional Coefficient Variation (CCV) for Cu realizations Masjed Daghi porphyry deposit, NW Iran. research, 100 scenarios loca...

The same non-covalent interactions previously found to affect the redox potential (E(m)) of the mononuclear T1 Cu protein azurin (Az) are shown to also fine-tune the E(m) of the dinuclear Cu(A) center in the same Az protein scaffold. The effects of these mutations are in the same direction but with smaller magnitude in the Cu(A) site, due to dissipation of the effects by the dinuclear Cu(A) cen...
