Authors: Wen Ai Cun , Zhang Heng Jia
Published: November 2013

An experiment was carried out to determine the effect of water deficit regulated with mulched drip irrigation on plant growth of processing tomato in an arid environment. The results indicated that Water deficit had little effect on plant height of processing tomato at full fruiting and late fruiting except that at seedling and flowering. Still, no effect of water deficit regulation on stem diameter was found at all measured growth stages.

Published: November 2013

We used methods such as microorganism cultivation and PCR-DGGE to examine the influence of glyphosate, paraquat, and xiao suo (used exclusively in China) on biodiversity. Two weeks after herbicide application, the strongest herbicidal effect was observed from paraquat, followed by glyphosate and then xiao suo. Although weed suppression was maintained over the effective period of each herbicide, surface vegetation gradually recovered after one month. Levels of soil bacteria and fungi were noticeably altered by exposure to herbicide. Actinomycetes were unaffected, however. Bacterial genetic diversity obviously changed, with some DGGE bands disappearing. Although several DGGE bands were lost, fungal genetic diversity remained constant. Actinomycetes remained constant. Overall, glyphosate and paraquat had stronger culling effects on surface plants than xiao suo, whereas glyphosate and xiao suo had stronger effects on soil microorganisms than paraquat. The results have implications for agriculture production, and provide information related to soil ecological stability and recovery for use in ecological management of economic forests.

Published: November 2013

The frequency and time of precipitation can influence the storage, allocation and management of water resources. But the precipitation frequency becomes more random and the precipitation process becomes more complexity due to the climate change and human activities, which increases the difficulty of technology and management. In this research, the fractal dimension based on Continuous Wavelet Transform (CWT) as the index of the precipitation complexity is applied to describe the precipitation process; using it, the complexity distributions of different precipitation processes in Liu-Kuang zone of Qingzhang basin China in different periods is illuminated respectively. The result indicates that in research region: (1) the annual precipitation frequency in the late period is less than that in the early period; (2) the urbanization and human activities increase the precipitation frequency. This result can reflect the frequency change of precipitation in changing environment and provide reference for the decision-making of water resources management in the local basin.

Published: November 2013

Corporate ethics and business ethics are becoming new requirements for a successful business in the 21st century. This trend continues to be strengthened throughout the industries and the construction industry cannot be exceptional. This research provides a practical framework of ethical decision making for construction together with the perceptions of construction professionals in respect to ethics and culture. A project factor approach is incorporated in the framework to reflect the unique feature of construction. The framework is based on Agent (virtue ethics) - Action (deontology) Results (consequentialism) model and the stakeholder concept of construction projects. The framework also intends to identify the ethical directions either mean-oriented or end-oriented. The effectiveness of the framework has been proved through a survey with construction professionals in Malaysia. The survey also includes cultural dimensions as ethic is a subset of culture. The outcomes of the survey shows that the construction professional in Malaysia are slightly more mean-oriented than end-oriented, and their cultural dimensions are more power oriented (PDI), more individualistic (IDV) and more masculine (MAS) compared to the Malaysia national level cultural dimensions.
