This paper analyzes the Brazilian Supreme Court (STF) Decision (ADPF n. 54) in which the court, by majority of votes, stated that the termination of the pregnancy of an anencephalic fetus does not constitute a crime of abortion. The paper analyzes the arguments used by the judges in their opinions to show that they agree on the conclusion, but strongly disagree on their reasons, with the result that the court remains deeply divided on the legal concept of life. The paper then points to the fact that the possibility of different majority positions regarding the decision and the arguments that justify it is not accidental, but the result of the court’s structure, which does not guarantee the collective rationality of the court’s decisions.

Citrus cultures have a fundamental importance to the Brazilian economy; certain aspects such as plant nutrition, yield, and fruit quality are vital for the citrus industry sustainability. The present study evaluated the nutritional status of manganese in adult Pear orange trees using different lime rates topically applied to the soil. The direct evaluation of lime rates effects on leaf manganese (Mn) levels revealed a decrease of the nutrient correlated to its increased, as well as passage of time between application and measurement. Foliar sampling 30 months after surface lime application evidenced a high correlation of foliar manganese levels with soil base saturation of 10-20 cm. Leaf manganese levels which showed a great probability of high productivity were between 33 and 70 mg kg-1.

The [Mn(4)(IV)O(5)(terpy)(4)(H(2)O)(2)](6+) complex shows great potential for electrode modification by electropolymerization using cyclic voltammetry. The electropolymerization mechanism was based on the electron transfer between dx(2)-y(2) orbitals of the metallic center and p pi orbital of the ligand.
