Bioreactor set-up and experimental design for sulfate reduction.
Integration of the metal biosorption process and the sulfate reduction process.
To treat an acid mine drainage, it was necessary to remove toxic metals, which have an inhibitory effect on this microbial consortium (data not shown).
Subsequently, the sulfate reduction process was carried out.
However, in the reactor effluent a significant reduction in the sulfate concentration is observed (Fig. 2).

Introduction Although technical papers dealing with the properties of concrete subjected to high temperatures are abundant, there are much difference among the data in the literature, on the residual strengths of concrete after sustained elevated temperature exposure, depending on concrete materials, mixture proportion, age and term of exposure, water evaporation, besides the exposure temperatures.
Some data indicated significant reduction in compressive strength after exposure at temperatures of 50℃ to 80℃, although most data indicated no reduction up to 100℃.
The test data shown in Figure.2 in indicated 15 to 25 % reduction in compressive strength when heated at 50℃, with smaller reductions when heated at higher temperatures up to 110℃, and 40 to 45% reduction in compressive strengths upon exposure.
The tensile strength after exposure expressed by the percentages of those of unheated concrete at the age of 91-days, shown in Figure.2 (b), indicated 10 to 45 % reductions after exposure at 50℃, 15 to 40% reduction at 80℃, with smaller reduction at 110℃ and 25 to 50% reduction at 300 ℃.
Although the data shown in Figure.3 are limited, it is clear that the minimal compressive strength after exposure at 50℃, were associated with the intermediate weight losses of 2.5 to 3.5 % in this experiment due to evaporation of free water.

This cycle time reduction helps increase the productivity of the washing process by 42.9%.
This cost reduction results from the reduction of the proportion of defectives from 12.8% to 1.78%.
This defective reduction decreases the rework cost of $16,800 per year.

Waste heat recovery and utilization in cotton manufacturing enterprise: energy saving and emission reduction aspects of a case study Min Zhu, Fanlong Kong, Yue Li*, Nan Wang, Min Xi and Lixia Zhao College of Chemical and Environmental Engineering, Qingdao University, Qingdao, 266071, China *Corresponding author:qdenv@126.com Keywords: energy saving and emission reduction, waste heat, CO2 emission.
Introduction Great pressure to curb carbon emission and increased need for energy have forced China to develop an “energy saving and emission reduction” (ESER) plan.
It not only makes energy efficient but achieves reduction.
The data into the formula, then Q11 = λA (ΔT / D) = 0.67 × 5127 × 17.5/0.15 = 400760.5 W, then turn the heat to calculate the other months.

In order to adapt to different environments, RFID technology needs a different antenna communication technology to achieve data exchange.
It can achieve both multi-band and antenna size reduction.
Compared to normal square patch antenna, this antenna has a good size-reduction feature.
The n iteration Minkowski fractal called Size-reduction characteristics of Minkowski fractal patch antenna.
Therefore, it has a good antenna characteristics and size-reduction feature for RFID applications.

Weather the emission reduction of SO2 being successful or not is the key for finishing the task of emission reduction of SO2 during “the Twelfth Five-Year Plan” in Sichuan Province.
In accordance with the population data of each city, energy data, and per capita living energy consumption of standard coal for domestic use, liquefied petroleum gas, natural gas in each city, etc. in the statistical yearbook of Sichuan Province, the emission factors [10] (showed as table 2) of SO2 in the rural and urban household cooking range are referred from the Discharge Coefficients Manual of Industrial Pollutants in The First Nationwide Pollution Source Census are adopted to calculate the SO2 emissions of the domestic area source in the Chengdu Economic Circle.
Therefore, the concentration distribution of SO2 in the whole economic circle can not be fully reflected only through monitored data.
Research on Pollution Control Measures Emission Reduction Objectives.
Therefore, the emission reduction of the SO2 becomes the actual need for the protection of ambient air quality.

And it is easy to study the reduction mode and effect.
The following is the data thattextile enterprises provided.
The carbon emissions in the following table are calculated according to the coal consumptionand production data which is provided by Haitian in 2009 and 2010.
The table3 shows the carbon emissions according to 2009 and 2010 coal consumption andproduction data.
Table 4 Carbon tax that Haitian and Fengzhu couldface (2009) CO2Emissions[tons] 10 yuan/ton CO2[yuan] 20 yuan/ton CO2[yuan] Haitian 51,600 515,900 1,031,800 Fengzhu 260,100 2,600,600 5,201,200 Above table of data can be seen the carbon tax has negative impact onnet profit.

The activity datas showed that 2V2Cu8Mn/TiO2 exhibited better activity.
Intensity data were collected over a 2θ range of 5°-85°.
The XRD phases were identified by comparison with the reference data from International Center for Diffraction Data (ICDD) files.
With increasing of Cu content and reduction of Mn content, the XRD peak of the CuO phase increased and the peak of Mn2O3 decreased.
