Stable, non-metallic, orbitally rearranged monoatomic transition elements selected from the group consisting of cobalt, nickel, copper, silver, gold, palladium, platinum, ruthenium, rhodium, iridium, and osmium having a doublet in the infrared spectra between 1400 and 1600 cm<-1> and having a ...
In the atmosphere samples, we found all the metals that were found in plants. In conclusion, medicinal plants can adsorb and accumulate some harmful chemical elements in their organs, are involved in the recirculation of these metals, and contribute air pollution....

transactionmay be defined as a consistent state change in the business relationship amongtwo or more parties,with each party maintaining an independent application system (or Web service) that maintains the state of each application. Business transactions form a good number of transaction types in ...
Atoms are the fundamental units of the elements and are defined by the number of protons in the atomic nucleus. Only relatively few of the chemical elements have active roles in the body. The electrons orbit the nucleus in electron orbitals that have definite energy levels. These electron orbita...
Measurement of the L3 to Mi, Ni and Oi subshells radiative transition probabilities of elements in the atomic number range 73 ≤ Z ≤ 92 The L3 subshell x-ray intensity ratios for Ta, W, Re, Au, Hg, Tl, Pb, Th and U have been measured using an Am-241 radioisotope. Radiative transi...
