F ROM time to time during the past several years, reports have filtered into the College of an unhealthy condition of cattle in the northern counties of New York State which clearly could not be diagnosed as de, ficiencies of phosphorus, calcium or a lack of total feed. As information concerning cobalt deficiency became more abundant, many points of similarity were recognized batween the sympto...

Aim. To study serum concentrations of trace and macro elements their correlations in children adolescents after antitumor therapy, depending on the presence or absence caries. Materials methods. The included 98 patients aged 4 to 17 years who were remission an therapy performed for acute leukemia lymphomas. Patients with carious tooth lesions group 1 ( n = 34) without caries – 2 64). We used in...

CaMnO(3) and Ca(2)Mn(3)O(8) were synthesized and characterized by SEM, XRD, FTIR and BET. Both oxides showed oxygen evolution activity in the presence of oxone, cerium(IV) ammonium nitrate and H(2)O(2). Oxygen evolution from water during irradiation with visible light (λ > 400 nm) was also observed upon adding these manganese oxides to an aqueous solution containing tris(2,2'-bipyridyl) rutheni...

The title compound, Mn(4)(H(2)O)(4)[Ge(OH)(2)(HPO(4))(2)(PO(4))(2)], was synthesized by the solvothermal method. Its crystal structure is isotypic with the iron and cobalt analogues [Huang et al. (2012 ▶). Inorg. Chem.51, 3316-3323]. In the crystal structure, the framework is built from undulating manganese phosphate sheets parallel to (010) inter-connected by GeO(6) octa-hedra (at the inversio...

Hip implants containing cobalt-chromium (CoCr) have been used for over 80 years. In patients with metal-on-metal (MoM) hip implants, it has been suggested that wear debris particles may contribute to metal sensitization in some individuals, leading to adverse reactions. This article presents data from a study in which the popliteal lymph node assay (PLNA) was used to assess immune responses in ...

The decline in global reserves of fossil fuels due to the increasing energy demand has caused the petrochemical industry to be interested in finding new energy sources. An alternative that should be considered is the technology based on hydrogen as it is friendly to the environment and its combustion is greenhouse. The technology based on hydrogen considers the synthesis of metal-organic materi...

Deep-sea mining is an emerging marine industry that presents particularly complex challenges due to its multi-faceted technological, scientific, environmental, social, industrial, political, economic and legal aspects, all of which must be addressed to achieve commercially viable results. These aspects are governed by the burgeoning regulatory regime promulgated by the International Seabed Auth...

New applications such as hybrid electric vehicles and power backup require rechargeable batteries that combine high energy density with high charge and discharge rate capability. Using ab initio computational modeling, we identified useful strategies to design higher rate battery electrodes and tested them on lithium nickel manganese oxide [Li(Ni(0.5)Mn(0.5))O2], a safe, inexpensive material th...
