Classification of solid industrial waste based on ecotoxicology tests using Daphnia magna: an alternative
Letícia Flohr,Débora Monteiro Brentano,Cátia Regina Silva de Carvalho-Pinto,Vanessa Guimar?es Machado
Biotemas , 2005,
Abstract: The adequate treatment and final disposal of solid industrial wastes depends on their classification into class I or II. This classification is proposed by NBR 10.004; however, it is complex and time-consuming. With a view to facilitating this classification, the use of assays with Daphnia magna is proposed. These assays make possible the identification of toxic chemicals in the leach, which denotes the presence of one of the characteristics described by NBR 10.004, the toxicity, which is a sufficient argument to put the waste into class I. Ecotoxicological tests were carried out with ten samples of solid wastes of frequent production and, on the basis of the results from EC(I)50/48h of those samples in comparison with the official classification of NBR 10.004, limits were established for the classification of wastes into class I or II. A coincidence in the classification of 50% of the analyzed samples was observed. In cases in which there is no coherence between the methods, the method proposed in this work classifies the waste into class I. These data are preliminary, but they reveal that the classification system proposed here is promising because of its quickness and economic viability.

Biotemas , 2006,
Abstract: Grinding operations are very significant among the manufacturing processes of the metal-mechanic industry. In conventional grinding, cutting fluids are of great concern for improving productivity, but also for being hazardous to the environment. In order to contribute to the knowledge of the actual toxic effects of these products in aquatic environments, the present work assesses the toxicity potential through acute toxicity tests of three different kinds of cutting fluids, with three different usage times. The tests were carried out using the fish Poecilia reticulate and the microcrustacean Daphnia magna as test organisms. These tests made it possible to determine the Median Lethal Concentration (LC50) for the fish and the Median Effective Concentration (EC50) for the microcrustacean. The results indicate that, after storage, the toxicity potential of cutting fluids decreases. However, in the three situations investigated, the product presented a high toxicity potential, which reinforces the need of special care in its handling, usage and disposal.

Abstract: O músculo vasto medial obliquo (VMO) desempenha importante papel na estabiliza o medial da patela. No entanto, o padr o de recrutamento dos componentes laterais, o músculo vasto lateral longo (VLL) e vasto lateral obliquo (VLO) n o está estabelecido. O objetivo deste trabalho foi analisar a atividade eletromiográfica dos músculos VMO, VLL e VLO de 21 indivíduos saudáveis (X=23,3 e DP=2,9), sendo 10 mulheres e 11 homens, sem história clínica de dor ou les o osteomioarticular. Para tanto foi utilizado um eletromiógrafo NICOLET VIKING II de 8 canais (NICOLET Biomedical Instruments) e eletrodos bipolares de superfície para registrar a atividade elétrica dos músculos VMO, VLL e VLO durante a realiza o de exercícios isométricos de extens o do joelho a 15o e 90o de flex o. Os dados eletromiográficos foram normalizados pela contra o isométrica voluntária máxima de extens o do joelho a 50o de flex o e revelaram que os músculos VLL e VLO apresentam diferen a significativa no padr o de recrutamento podendo ser considerados fisiologicamente distintos. O músculo VMO desempenhou juntamente com o VLO um papel recíproco e sincr nico na estabiliza o patelar e apresentou maior ativa o em rela o ao músculo VLL nos exercícios isométricos de extens o do joelho a 90o.

Abstract: In this article, I will reconstruct, through brief stories, some of the traits that characterize the way of life of families in the El Salvador neighborhood, in Buenos Aires, Argentina, go scavenging everyday in Buenos Aires city. These stories will not only tell us who they are and how they arrived at the El Salvador neighborhood, from where, and in what manner they began to salir con la carreta, but will also permit us to move closer to the day-to-day existence of these families in relationship to their life in the barrio and the activities they engage in, thereby giving us a fuller understanding of family dynamics. In the research that originated this paper, I followed an ethnographical perspective to study and analyze the way of life of those families living from the recyclable waste they recollect in Buenos Aires city.

Abstract: The purposes of this paper were to investigate (d) whether vastus medialis obliquus (VMO), vastus lateralis longus (VLL) and vastus lateralis obliquus (VLO) EMG activity can be influenced by hip abduction performed by healthy subjects.Some clinicians contraindicate hip abduction for patellofemoral patients (with) based on the premise that hip abduction could facilitate the VLL muscle activation leading to a VLL and VMO imbalanceTwenty-one clinically healthy subjects were involved in the study, 10 women and 11 men (aged X = 23.3 ± 2.9). The EMG signals were collected using a computerized EMG VIKING II, with 8 channels and three pairs of surface electrodes. EMG activity was obtained from MVIC knee extension at 90° of flexion in a seated position and MVIC hip abduction at 0° and 30° with patients in side-lying position with the knee in full extension. The data were normalized in the MVIC knee extension at 50° of flexion in a seated position, and were submitted to ANOVA test with subsequent application of the Bonferroni multiple comparisons analysis test. The level of significance was defined as p ≤ 0.05.The VLO muscle demonstrated a similar pattern to the VMO muscle showing higher EMG activity in MVIC knee extension at 90° of flexion compared with MVIC hip abduction at 0° and 30° of abduction for male (p < 0.0007) and MVIC hip abduction at 0° of abduction for female subjects (p < 0.02196). There were no statistically significant differences in the VLL EMG activity among the three sets of exercises tested.The results showed that no selective EMG activation was observed when comparison was made between the VMO, VLL and VLO muscles while performing MVIC hip abduction at 0° and 30° of abduction and MVIC knee extension at 90° of flexion in both male and female subjects. Our findings demonstrate that hip abduction do not facilitated VLL and VLO activity in relation to the VMO, however, this study included only healthy subjects performing maximum voluntary isometric contracti
