A presente invenção se refere à síntese e caracterização de complexos fosfínicos de rutênio (II) contendo o íon picolinato e/ou dilminas e/ou bifosfinas com ótima atividade farmacológica na inibição do crescimento da micobactéria da tuberculose. Tais complexos poderão primeiramente ser utilizados na indústria química e a médio e longo prazo na indústria farmacêutica. A presente invenção descreve também como foi realizada a determinação da atividade contra o bacilo da tuberculose, bem como avalia a toxicidade dos complexos contra as células de macrófagos onde o bacilo da tuberculose se internalíza.

This study aimed to evaluate and characterize the chemical properties of soil organic matter under two periodically flooded forest formations on the island of Marambaia, Rio de Janeiro. These formations differ on the degree of soil water saturation, caused by the influence of water table, and in the (F1) formation presents the water table nearer the surface compared to the (F2) formation. Samples were collected in layers from 0.00 to 0.05, 0.05-0.10 and 0.10-0.20 m. The soil properties evaluated were: pH, H+ + Al+ 3, Ca+2, Mg+2, Na+, K+, P, N, total organic carbon (TOC) and base saturation (V%), humin carbon fraction (C-HUM), carbon of humic acid fraction (HAF-C) and fulvic acid fraction carbon (FAF-C). Statistically higher pH values were observed for F1. In F2 there are higher values of Mg+2, P, N and V% value. Correlation was found between the concentrations of Mg+2, N, humic acid and fulvic acid with water table in F1, and water table in F2 with Na+ and K+. Fraction C-HUM was more representative of the total organic carbon, followed by C-HAF and C-FAF. The TOC levels were higher in F1. The C /N ratio was lower in F2, with values ranging between 9 and 12, and F1 were found higher values of this relationship, ranging from 9 to 15. Among the pathways of formation of organic soils in both areas it appears that the major route for organic matter accumulation is the inheritance route.

Incomplete glimpses of the philosophy of Charles Peirce (1839-1914) can frequently be found in studies about Semiotics and Information Science. Therefore, we sought to discover the theoretical and applied interrelationships between knowledge and information organization and Peirce's Semiotics and Philosophy. The aim was to discover and evaluate the contributions of Peirce's Semiotics and Philosophy to the knowledge and information organization field. The method of this study was bibliographical research. The main results were: indexing process semiotic model, semiotic knowledge organization, interaction between documentary semiotics and documentary languages, kinds of inference to the indexing process, as well as the collaboration of Peirce's pragmatism to terminology theory. Finally, we listed issues for future research.

This text aims to present a very short review on Machiavelli’s ideas reception concerning his military thought and short reflections on international affairs, as part of what was called realism in the realm of international relations theory. The text deals with much more emphasis the mentioned interpretations in a very concise way within contemporary studies about maquiavelian legacy on contemporary studies in International Relations.
