The molybdenum (Mo) levels in the plasma and urine of 30 premature and 15 full-term infants have been compared with the Mo intakes and urine uric acid excretion (uric acid/creatinine ratio) produced by the Mo enzyme xanthine oxidase. The Mo intakes of full-term infants were 41 +/- 14 nmol/kg/day (mean +/- SEM). In the premature group breast milk supplied significantly less Mo (4.3 +/- 0.4 nmol/...

A chemical invariant of graphical structure Z is a unique value characteristic that remains unchanged under graph automorphisms. In the study QSAR/QSPR, like many other invariants, reciprocal degree distance has played significant role to estimate bioactivity several compounds in chemistry. Reciproca...

The principle purpose of this article is to examine some stability properties for the fixed point below rational difference equation U n + 1 = ξ − 8 ε 2 <...

Oxidative dehydrogenation (ODH) of propane was studied on zirconia-supported molybdenum oxide catalysts. The structure of the ZrO2 support and of the dispersed MoOx species was characterized by X-ray diffraction and by Raman and UV–visible spectroscopies. The structure of dispersed molybdena depends on the Mo surface density and on the temperature at which catalyst precursors are treated in air...

Molecular descriptors are a basic tool in the spectral graph, molecular chemistry, and various other fields of mathematics chemistry. Kulli–Basava K mathvariant="fraktur">B indices were initiated for chemical applicatio...

Due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. The known world class Cu-Mo deposit, Sarcheshmeh Porphyry deposit (central Iran) selected as the study area. The Hypogene zone of the deposit was chosen as the space in which estim...

Bioleaching processes for extraction of Cu and Mo from molybdenite cons. are more environmentally friendly and consume less energy than conventional technologies, yet less economically efficient. One necessary step towards arriving at a cost-effective bioleaching process is using appropriate methodology to optimize pertinent factors in such processes. To this end, the present study employed Res...
