Highly oxygenated fullerenes, C(60)O(n) with 1 ≤ n ≤ 13, have been prepared by the Mo(O)(2)(acac)(2) catalysed oxidation of C(60) with (t)BuOOH. Increasing the catalyst : C(60) ratio or increasing the reaction temperature increases the yield as well shifting the product distribution to higher oxygenated products, in contrast, increasing the (t)BuOOH concentration shifts the product distribution...
Neospora caninum is a worldwide parasite recognized as one of the main parasites responsible for abortion in cattle. The objective of this study was to evaluate vertical transmission of N. caninum in dairy cows (Bos taurus) that were slaughtered at an abattoir in the state of Santa Catarina, southern Brazil. Blood samples (with and without EDTA) from 60 pregnant dairy cows and blood and tissue ...
Scaling behaviors of the global monthly sea surface temperature (SST) derived from 1870-2009 average monthly data sets of Hadley Centre Sea Ice and SST (HadISST) are investigated employing detrended fluctuation analysis (DFA). The global SST fluctuations are found to be strong positively long-range correlated at all pertinent time-intervals. The value of scaling exponent is larger in the tropic...
SSZ-60 is a new borosilicate zeolite that may be prepared using N-ethyl-N-(2,4,4-trimethylcyclopentyl)pyrrolidinium or N-ethyl-N-(3,3,5-trimethylcyclohexyl)pyrrolidinium as a structure directing agent; the framework of SSZ-60 was determined by the FOCUS Fourier recycling method, its structure refined in space group P21nm and found to possess a one-dimensional channel system with pores delimited...
