Authors: Jia Xian , Chu Zhi Bing , Huang Qing Xue , Ma Li Feng
Published: October 2012

Rolling-cut bilateral shear is a sort of auxiliary equipment with arc upper blade performing pure rolling over flat lower one. The working principle are characterized as up-and-down movement of upper blade by crank shaft, after the rotation caused by the phase difference between two shafts, which makes upper blade rotate to adapt to steel shearing with different thickness. Through analysis the processing of rolling-cut bilateral shear and make the shearing mechanism simplify 8-linkage, and then the kinetics formula of shearing mechanism was established. The relationship of crank shaft length of rolling-cut bilateral shear in shearing process and movement trace of upper blade (shearing overlapping) was obtained as well as the change rule of length of linkage over upper blade, which provides the theoretical support for the design of rolling-cut bilateral shear.

Published: October 2012

One hundred and forty lactobacillus strains which were obtained from infant faeces and traditional fermented foods in western China were examined for possible use as probiotics. The live whole cells from lactobacilli were tested for antiproliferative effects, adherent capability, acid and bile tolerance on colon cancer HT-29 cells. The results showed that eleven strains inhibited growth of HT-29 cells. Among the eleven strains, ten strains were further screened out through adhering activity assay. All the ten strains could grow in acidified broth at pH 1.5 and in 0.3% (w/v) bile salt. Nevertheless, G5, X11, X12, M5, M23, K11 and K14 showed the most profound inhibitory activity against HT-29 cells. While Q12, SB27, X2 and M7 were poorly presented. 16S rRNA gene sequences indicated that X12, M5, M7 and M23 were Lactobacillus paracasei, G5, Q12, SB27, X2, X11 and K14 were Lactobacillus casei, K11 was Lactobacillus rhamnosus. Together, these results suggest G5, X11, X12, M5, M23, K11 and K14 to be good probiotic candidates and potential application in functional foods and health-associated products.

Authors: Zhang Bin , Deng Shang Gui , Lin Hui Min
Published: October 2012

Changes in chemical, textural, and volatile flavor properties were investigated for mackerel fish (Scomberomorus niphonius) stored in cold rooms and freezers. Correlation and multivariate analysis showed a significant time-dependent relationship between TVBN/TMA (Y) and storage time (X) for fish stored in cold rooms, with R=0.996-0.997 values of Gompertz model (Y=a*exp(-exp(b-cX)), and there was a good linear relationship between TVBN and TMA. Combined with the textural properties, the polynomial fitting model (Y=a+bX+cX2+…, R=0.982-0.991) was applied and elucidated the correlation between hardness/springiness (Y) and TVBN (X), the rational function model (Y=(a+bX)/(1+cX+dX2), R=0.975-0.979) used for the chewiness (Y) and TVBN (X). The electronic nose analysis revealed that the variation of muscle volatile flavor compounds was found out along the PC1 to the right, and then along the PC2 to the upward and further to the downward based on the principal component analysis (PCA). Furthermore, the linear discriminant analysis (LDA) had better distinction effect for the changes of fish flavor than PCA. Results from this study suggested that the texture analysis in combination with electronic nose techniques might be utilized as a rapid expeditious process for predicting freshness and shelf life of the alive-storage fish or other aquatic products.

Authors: Li Shi Yun , Hu De Sheng
Published: October 2012

Grafting copolymerization method was used to synthesize copolymer of polyethylene with single-walled carbon nanotubes (SWNTs). Firstly, SWNTs were functionalized along their side walls with 1-alkene organic groups using the 1, 3-dipolar cycloaddition reaction. Then, a metallocene catalyst C2H4[(tert-H)Ind]ZrCl2 was used to synthesize polyethylene grafted from SWNTs (PE-g-SWNTs) copolymers by copolymerization with ethylene. SWNTs can be used to compound PE-g-SWNTs nanocomposites by a grafting copolymerization approach. The results show that PE covalently grafted from organic functionalized SWNTs forming a strong interface between the SWNTs and the PE matrix. The microstructure of the obtained copolymers was characterized. The SWNTs were dispersed well in the copolymers due to covalent linkage of functionalized SWNTs with polyethylene. Thermal stability of PE-g-SWNTs is better than those of pure PE and PE/SWNTs physical mixture. It indicates that the addition of SWNTs by the grafting copolymerization approach is mainly due to the delay of the thermal decomposition temperature in PE matrix.

Authors: Liu Yu Mian , Hu Wei Ping
Published: October 2012

Common glass for architecture had only one function, i.e., transparency and the requirement for indoor health made “environmental protection type” novel glass necessary. In the present study, a novel self-cleaning glass was prepared by sol-gel method. To form self-cleaning glass, common glass was adopted as the foundation base and TiO2 coatings were cover its outside surfaces. The novel glass had little change in shape but alteration to slightly white compared to common glass, thanks to white TiO2. The self-cleaning glass could reduce formaldehyde concentration of air from more than 160 mg•m3 to 0.4 mg•m3 within 60 h, while the common glass could cut down to ca. 30 mg•m3 and reaching equilibrium before 24 h. The removal of formaldehyde by common glass could be owing to adsorption action and slightly gradation by ultraviolet light, and the removal by self-cleaning glass could be mostly assigned to photodegradation by TiO2 when ultraviolet light irradiation. Besides, the self-cleaning glass exhibit 74.99% and 91.60% anti-bacteria rate to Escherichia coli and Staphylococcus aureus, respectively, when common glass was chosen as control. In brief, the self-cleaning glass was proved excellent to remove formaldehyde and inhibit bacteria. As a result of the non-preference of the photodegradtion and anti-bacteria by TiO2, it was believed the self-cleaning glass could remove almost all the kinds of indoor organic gases and inhibit almost all the kinds of bacteria, including some pathogens. The self-cleaning glass had great potential in interior finish application meeting the challenge for environmental protection.

Challenges for Tourism in Natural Areas – Cost of Carbon and Natural Disasters
Authors: Becken Susanne , Ren Pei Yu
Published: October 2012

Tourism involves travel, and travelling is inherently dependent on carbon-based fuel. The low cost of carbon fuels resulted in massive expansions of global tourism with many countries now depending on tourism exports for their national economies. However, oil is a finite resource and tourism’s dependence on it creates major vulnerabilities. It is also increasingly recognised that to combat man-made global climate change it is essential to put a price on carbon, for example through carbon taxes or Emissions Trading Schemes. The implications of a diminishing availability of cheap carbon-based fuel are extremely complex and far reaching, both for society as a whole and for tourism.

Published: October 2012

Coking wastewater is generated from metallurgy industry and it contains many highly toxic substances. Because the coking wastewater would bring about severe environmental pollution, it is best to reuse it as circulating cooling water. However, there are large quantities of ions in coking wastewater, which would cause serious corrosion to the pipe and the devices in the process of recycling. Therefore, desalting techniques are necessary for the reused of coking wastewater. Electrosorption technique (EST), as a new type of water treatment technology, can meet the economic benefits of water treatment technology. It also can achieve better water quality and reliability standards which have never been achieved before. In this paper, a new electrosorption device was invented and it was used for desalting of coking wastewater. The main parameters affecting the electrosorption of ions including voltage, electrosorption time, pH value, temperature and electric current have been investigated in detail. Under the optimized experimental condition, after electrosorption process, a salt removal rate of 75% was obtained. The quality of effluent could satisfy the criterion of industrial circulating cooling water (GB 50050-2007) and could be reused as the circulating cooling water in coking plant.

Published: October 2012

Environmental degradation and unsustainable use of water resources has become an obstacle to further economic development and the well-being of the population in the Li River basin. This paper explores the concept and principles of integrated water resources management (IWRM) in relation to their applicability to the Li River basin. The assessment on its physical and socioeconomic characteristics and its current institutional systems in the Li River Basin provides an appreciation of the whole river basin. Sectoral fragmentation and the absence of coordination mechanism (or body) are identified as the institutional factors in this study that caused water related issues. In order to overcome shortfalls of the current fragmented management system, formation of Watershed Management Committee is highly recommended as the core of reforming efforts, which is expected to coordinate effective planning and implementation of equitable, efficient and sustainable use of natural resources in the basin with a view to improving the sustainability of its economic development. Several other reform recommendations are also provided and expected to be a departure point towards better water governance in the Li River basin through the implementation of IWRM. Lastly we explore to what extent the proposed recommendations would be supported by the current national policy framework.

Published: October 2012

In this paper, the surface finishing process of anti-alcohol, anti-oil and antistatic was applied on terylene needle-punched nonwoven filter material. We used contact angle, anti-alcohol grade, anti-oil grade, static voltage and half-life period as the main indicators for evaluating the effect of the finishing. The organic fluorine TG-410C and nonionic antistatic agent TF-481 were selected as finishing agents. The single factor experiments and orthogonal experiments were carried out on four effect factors of the finishing, including volume percent of organic fluorine, volume percent of antistatic agent, baking temperature, baking duration. The results show an optimum formula: the volume percent of organic fluorine is 20%, the volume percent of antistatic agent is 15%, baking temperature is 170°C, and baking duration is 7min. After finishing, anti-alcohol grade can reach level eight, anti-oil grade can reach level five; the half-life period is less than 1 second. So it can be employed in filtering the air and reducing dust particle and concentration.
