SUMMARY Lignification-associated phenolic acids are widely distributed in graminaceous plant cell walls. Nylon bags containing maize bran, wheat bran, millet husk and rice husk were incubated in the rumens of five Charolais (♂) × Nanyang (♀) crossbred steers for 6, 12, 24, 36, 48 and 72 h. The in situ ruminal disappearance of ester-linked phenolic acids linearly increased in the brans with increasing incubation time, and the disappearance was greater for ester-linked ferulic acid (FAest) than for ester-linked p-coumaric acid (PCAest). The disappearances of FAest and PCAest were positively correlated with disappearances of neutral detergent fibre (NDF), cellulose and hemicellulose. The effective degradabilities of NDF, cellulose and hemicellulose in the brans were markedly greater than the effective degradabilities of these components in the husks, and were negatively correlated with the contents of Lignin (sa), ether-linked ferulic acid, PCAest and ether-linked p-coumaric acid in both the cereal brans and husks. These findings suggested that breeding forage crops with modified phenolic acid contents could represent an alternative strategy to promote further increases in fibre digestibility of cereal residue feeds for ruminant animals.

This paper proposed an embedded system to acquire and storage images periodically based on STM32 and transmit images with GPRS to monitoring center. Monitoring center can also send command to acquisition terminals over GPRS. Acquisition terminals are based on STM32 characterized by low energy consumption and high performance. Experiments showed acquisition terminals were stable and reliable in acquisition and image storage, capable of controlling different acquisition angels and uploading images to monitor center. The packet loss probability is less than 10% and average time delay is 2 seconds. © 2015 IEEE. Source

According to ISA100.11a standard, a new gateway access method based on application layer was proposed in this paper which realized the communication between wireless sensor networks and Ethernet. It was C/S structure and completed on the Linux operating development platform. The system mainly contained four modules: Ethernet interface module, data storage module, protocol conversion module and wireless interface module. Each module was responsible for different functions, so as to communicate and exchange data with each other for various protocols. Two test programs were carried out; experiment results showed the gateway was stable and reliable. It can effectively achieve internal data management and remote monitoring in wireless sensor networks. © 2014 IEEE. Source

Some chain and control based researches have been done on security of agriculture industry. They showed that foreign investments have held market power and been the biggest threat to a host country because of mergers and acquisitions by controlling each series of vertical functions in mordern agriculture. They choose to control points by analyzing the different grades of controlling difficulty among each vertical function. Firms and the government of the host country should make measures to protect their agriculture. Source

Over the last three decades, China's agriculture sector has been transformed from the traditional to modern agriculture practice through the effective deployment of Information and Communication Technologies (ICT). Information processing and dissemination have played a critical role in this transformation process. However, there are very limited publications regarding the China's success and lessons learned in utilising ICTs to support Agriculture development and transformation. This paper aims to contribute to a better understanding on how different ICT-based information service models are designed and adopted in China; and to share the knowledge and experience in applying emerging ICTs in disseminating agriculture information to farmers to improve productivity and economic, social and environmental sustainability. The paper reviews and analyses the China's agricultural information service systems and models. Seven ICTbased information dissemination models are identified and discussed. Successful cases are presented to demonstrate the impacts of different service models. The findings provide a useful direction for researchers and practitioners in developing future ICT based information processing and dissemination systems. It is hoped that this paper will also help other developing countries to learn from China's experience and best practice in their endeavor of applying emerging ICTs in agriculture information dissemination and sharing.
