Chromium is a heavy metal used for various applications such as in the manufacture of stainless steels, in chemicals for wood treatment, in tanneries, and in the refractory industry. The main problem associated with the use of chromium in these activities is the considerable volume of contaminated effluent that requires treatment, mainly due to its high mobility and toxicity in its hexavalent form. Immobilization methods arise as an efficient solution for the treatment of these wastes through converting them into inert and stable materials. The present paper aims to investigate Portland cement II’s paste properties with potassium dichromate addition in order to verify the chromium immobilization process. Analyses of moisture content, water absorption, axial compressive strength, and solubilization were done in samples at 7 and 28 days with 0%;0.5%;1.05;1.5%;2.0% and 2.5% potassium dichromate addition. The results showed the influence of this salt in cement hydration reactions, damaging the mechanical behavior and the water absorption capability of the material produced. In the solubilization test, all compositions had >99% efficiency of chromium immobilization in both ages of hydration, thus demonstrating the capability of a cementitious matrix to stabilize this metal.

Background Electromyography (EMG) biofeedback has been used in spinal cord injury rehabilitation, but optimal indication and treatment protocols still need to be identified. Objectives To use an operant conditioning learning paradigm to compare the EMG responses in subjects with spinal cord injury for optimal indication of EMG biofeedback treatment. Participants Thirty rehabilitation outpatients with incomplete cervical spinal cord injury. The subjects were divided into three groups based on their scores on the ASIA scale (ASIA B, ASIA C and ASIA D groups), with ten patients in each group. Methods Repeated-measure trials were conducted to compare patients’ EMG responses between pre-initial and post-biofeedback treatment. In the sessions, visual feedback of EMG activity of the triceps brachii muscle was provided to the patient in accordance with the treatment protocol. Results One-way ANOVA and the Kruskal-Wallis test were used to examine the differences in the measures between groups. The initial EMG and final EMG measures were not significantly different between the ASIA C and D groups, but these measures were different between the ASIA B group and the ASIA C and D groups. In the ASIA B group, the EMG responses started out lower than those in the other groups and varied less, especially in comparison to the ASIA C group. Conclusion: These results reveal that the patients classified as ASIA C and D achieved better responses of the operant conditional learning protocol and optimal indication for the biofeedback treatment.
