Salt Water intrusion is a recurrent phenomenon over the world. This study has purpose to find a new biological way to solve this problem. Sporosarcina Pasteurii, known for its application in biogrouting solutions, was injected into four experimental columns submitted to salt water injection. The bioremediated carbonation reaction was induced by injection of calcium chloride and urea during a three weeks period and results were observed by a new injection of salt water. The increase of salt concentration in the columns after biological treatment shows a slowing down of salt propagation after treatment.

In this paper, the design of data acquisition system of intelligent community based on USB interface is developed, the method and process of design scheme, a set of data acquisition system composed of the United States of America Cygnal company's C8051F320 chip on the development, and proposes the implementation, through the practice has proved the feasibility of the scheme.

According to the number of users and the electricity measurement requirements for building, a novel intelligent system of single phase electric meter for building has been proposed in this paper. It is aiming at the application status and existing problems of watt-hour meter used in China. It has been designed by using the decentralized power parameter detection and centralized control method. The following designs of the intelligent system have been done in the study: the topological structure, hardware and software. According to the design of the intelligent system, the intelligent system of single phase electric meter for building can be developed. The electricity signal processing module, memory, GUI and the communication module are controlled by MCU. The intelligent system can easily measure various parameters, record data safety, calibrate meter with software, and it has more communication interface. The system can be realized functions, such as the monitoring, management, protection, wireless transmission and so on. It can be widely used in ordinary households, residential users, student apartments, office buildings, etc. to achieve the electricity detection, monitoring and controlling intelligently.

This paper introduces a design of PLC based intelligent control system for telescopic conveyor.The system is designed closed loop speed control module, electrical energy saving module and automatic alarm module. PLC technology improves equipment centralized control degree, frequency converter improves control accuracy and efficiency. These can embody the automation design, energy-saving design and safety design concept.
