The invention relates to the synthesis and characterisation of ruthenium(II) phosphine complexes containing picolinate and/or diimine and/or biphosphine ions and having an outstanding pharmacological activity for inhibiting the growth of tuberculosis mycobacteria. These complexes can first be used in the chemical industry, and in the medium and long term, in the pharmaceutical industry. The invention also describes how the activity against tuberculosis bacillus was determined, and how the toxicity of the complexes against macrophage cells within which the tuberculosis bacillus grows was assessed.

The objective of the present study was to evaluate changes in chemical characteristics of soil and yield response of lettuce fertilized with organic compounds from waste and/or raw materials. Treatments were arranged in a randomized block design in a 5 x 4 factorial scheme, with five types and four doses of organic compounds, with four replications, applied to plants grown in pots for 35 days under greenhouse conditions. In the soil, the evaluated variables were: organic matter content, nutrient content -P, K+, Na+, Ca2+ and Mg+2, potential acidity (H+ + Al3+), sum of bases (S value), cation exchange capacity (CEC), base saturation (V%) and pH. In plants, dry matter yield of shoot was assessed. The addition of organic compounds increased the dry matter yield of the lettuce and organic matter content in soil, favoring the increase of phosphorus and exchangeable sodium in soil, also, increase in calcium and potassium were observed, with use of some compounds. Compounds 3 (domestic, urban and industrial residues) and 4 (Commercial Composto - Greenworld), mainly, improve the chemical characteristics of soil and reduce potential acidity.

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.
