Investigation of the toxicity of the products of decoloration of Amaranth by Trametes versicolor

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application.

Numerical and experimental investigation of state of health of Li-ion battery

ABSTRACT

Estimation of State of Health (SoH) of Lithium-ion (Li-ion) battery is essential to predict the lifespan of batteries of an electric vehicle (EV). The efficient prediction of battery health indicates to the effective and safe operation of EV. However, delivering an effective and accurate method for the estimation of SoH in the real condition is truly a challenging task. The present study proposed a holistic procedure of combining both experimental and numerical investigations to conduct the fundamental study on coupled mechanical-electrochemical behavior of Li-ion battery. The proposed investigation highlighted the effect of stress on the capacity of the battery, considering capacity fade as an equivalent parameter to its health for real-time estimation of SoH. Finally, a simple model of Artificial Neural Network (ANN) is provided, which shows the linear dependency of stress with the SoH. The results obtained from the ANN model are validated with a Linear Regression (LR) model for a better understanding of the inspection. The predicted value of mean Square Error (MSE) and R square error in the ANN training model are found to be 0.000309 and 0.849687, respectively. Whereas for the test model, these predicted values are found to be 0.000438 and 0.819347, respectively.

Patterns of television viewing and of perceptions of hazards to life

A previous study using respondents in a London regional audience appreciation diary panel showed that links existed between overall amounts of the viewing of television recorded across one week and levels of perception of risk of three hazards to life, namely lightning, flooding and terrorist bomb attacks. With a fourth hazard, cancer, there was an inverted U-shaped relationship between perceived risk level and amount of viewing. At the same time there were no relationships between amounts of viewing of news and documentary material and perceived risks of any of 12 hazards. Two new surveys were done, nearly three years after the previous one, asking people in widely different regions about their perceptions of nine various hazards, and linking these results with measures of attitudes towards certain adaptations of new technology (which could prove hazardous or beneficial according to points of view) and to patterns of television viewing. The two surveys agreed on a wide number of points with each other; they agreed with the previous study in finding no steady relationships between information programme viewing and hazard perception. Lightning and flooding were again related, this time more specifically with viewing of particular types of television programming. A new finding is that heavier viewing of television sport is associated with less perceived risk of cancer and of nuclear pollution. Interpretations are generally favoured along the lines of a selective process of viewers with certain predispositions choosing certain kinds of viewing patterns, rather than that programme contents provide an example for formulating perceptions and attitudes.     

开发白洋淀旅游资源的制约因素与对策

作者在实地调查研究的基础上，认为制约白洋淀旅游业发展的因素主要有水位不稳、水质受到污染、旅游项目内容贫乏、参与性差、景区文化氛围不和谐，以及管理不到位。作者提出，应努力保持其水位稳定，加强流域内污染治理，理顺管理体制，建立白洋淀湿地保护区，加大旅游资源开发和宣传力度，丰富旅游的文化内涵等来保证白洋淀旅游的可持续发展。
