| Antidepressants are among the most prescribed pharmaceuticals throughout the world. Their presence has already been detected in several aquatic ecosystems worldwide and their effects on non-target organisms justify the growing concern of both the public and regulatory authorities. These emerging pollutants do not occur as isolated compounds but rather as multi-component mixtures, which may lead to increased adverse effects compared to individual compounds. Freshwater and marine algae seem particularly sensitive to pharmaceuticals, including antidepressants. Studies assessing the toxicity of antidepressant mixture to algae focused mainly on binary mixtures of selective serotonin reuptake inhibitors. In the present experiment, the freshwater algae... |

| The effects of sublethal concentrations of cadmium (0.64 µg/L), iron (0.043 mg/L) and zinc (0.31 mg/L) and a mixture of these metals on succinate dehydrogenase (SD) and alkaline phosphatase (AP) activity and on structural changes in the mitochondria of epithelium cells of the digestive tract were examined in the oligochaete Limnodrillus hoffmeisteri after 96 h of exposure in artificial sediments. SD activity was significantly inhibited, particularly in treatments with Cd alone (92.57%), while AP increased its activity with Cd alone (73.23%). However, when this metal was mixed with Fe and Zn, the inhibition of SD activity was lower (67.82%) than with Cd alone, showing an antagonistic effect and AP increased its activity (73.26%). Mitochondria were... |

| Some technical and economic problems currently limit the use of substrates. The main problems include the lack of reciprocal adaptation of the cultivation technics and the substrate,the possible presence of pathogens, and the cost involved. To these we must add the ecological problems of the extraction areas, since there are no short-term renewable resources, especially in peat, the classic substrate. This has motivated the search for substitutes, especially amongst indigenous materials and those easily obtainable locally, such straws cereals, rice husk and cork residuous. The use of these substrates should be evaluated agronomically for: physical, chemical and cultural properties. The characterisation and use of almond shell (Prunus dulcis) as a... |

| The identification and interpretation of discrepant observations in sensory experiments are difficult to implement since the external effects are associated with the individual consumer. This fact becomes more relevant in experiments that involve blends, which scrutinize coffees with different qualities, varieties, origins, and forms of processing and preparation. This work proposes a statistical procedure that facilitates the identification of outliers while also evaluating the discriminatory powers of a sensory panel concerning the differentiation of pure blends and coffees. For this purpose, four experiments were performed that tested coffees with different qualities and varieties. The results suggest that the statistical procedure proposed in this work... |

| The objective of this study was to verify the influence of temperature on crystallization of binary and ternary mixtures of two hydrogenated fats and soybean oil, by polarized light microscopy at temperatures of 30° C, 35° C, and 40° C. The types of crystals observed were spherulites type A, and B and the polymorphic forms were ß , and ß -prime. The soybean oil does not contribute statistically to total area or maximum diameter of the crystals. At 35° C the positive relative coefficients to the interactions presented, in general, absolute values higher than the negative ones, pointing that the crystals were larger than what could be expected, if there was no interaction among the components. At 40° C the negative relative coefficients revealed, in general,... |
