- The Chinese government has been promoting the anaerobic treatment technology not only for pollution control but also for bioenergy recovery. Millions of decentralized anaerobic digesters have been built using animal manure and crop stalk as feedstock to improve the sanitary conditions and to produce biogas for heating and lighting for farmers and rural communities. Also, there are 22,570 medium to large sized anaerobic projects built for centralized animal manure treatment. In addition, over 2,000 medium to large anaerobic systems have been installed since 2000s for the treatment of industrial wastewaters including alcohol, starch, pulp and paper using technologies such as CSTR, UASB, EGSB, IC, etc. Overall, more than 25,100 medium to large sized anaerobic systems are now in operation in rural China, producing annually 7.5x109 m3 of biogas. Based on Chinese government’s 12th Five-Year Plan, biogas output will reach 21x109 m3 by 2020 from treatment of industrial wastewater, poultry wastes, municipal wastes and wastewater sludge; this amount will double by 2050. This Chapter is to summarize the development of anaerobic technology in China in the countryside as well as in industrial wastewater treatment. A number of case studies are present.

- At least half of the local galaxies reside in galaxy groups, which indicates that the group is the common environment where galaxies evolve. Therefore, it is important to probe how significantly galaxies are affected by group environmental processes, in order to obtain a better understanding of galaxy evolution. We carried out a new CO imaging survey for 31 galaxies in the IC 1459 and NGC 4636 groups, using the Atacama Compact Array, to study the effect of the group environment on the molecular gas properties and the star formation activity. With our resolved CO data, combined with high-resolution H i images, we find asymmetric CO and H i distributions in the group galaxies. Compared to isolated galaxies, group members have relatively low molecular gas fraction and low star formation rate. These results suggest that the group environment can change the properties of cold gas components and star formation in group galaxies.

- The application of carbon nanotubes (CNTs) for wearable sensing device fabrication is an interesting area, attracting sustained scientific and technological interest. Acquisition of information from wearable technologies is considered a cornerstone in person-centered health informatics, because of its independence, currency, and timeliness. The unique physical and chemical properties (such as high aspect ratio, ultralight weight, high mechanical strength, high electrical conductivity, and high thermal conductivity) of CNTs make them an attractive nanomaterial for wearable sensor fabrication. Extensive efforts will continuously be made in both academia and industry in the research and development of wearable CNT sensors to enhance their function, flexibility, energy saving, and longevity. We will discuss recent advances in the design and application of wearable devices based on CNT materials for sensing, especially in the fields of medical equipment, motion detection, and environmental sensor.

- Bismuth can modify surface reconstruction of III-V semiconductors and affect their growth conditions. Bismuth incorporation into III-Vs strongly changes their electronic properties. We present an overview of how the above Bi-related effects influence structural and optical properties of III-V nanostructures.

Supporting Machine-to-Machine Communications in Long-Term Evolution Networks

- Abstract This chapter describes key challenges that must be faced to turn long-term evolution (LTE) into a suitable technology for machine-to-machine (M2M) and machine-type communications (MTC). In particular, the challenges dealt with in this chapter relate to managing a large number of devices, attaining very low energy consumption, ensuring low-complexity protocols to bring down the cost of devices, and extending coverage to facilitate one-hop transmissions. Beyond being technically feasible, network operators must adopt network optimization; therefore, a techno-economic perspective is presented in this chapter as well. Business-related requirements and implications that emerge from the traffic mix between humans and machines are covered, including scalability and deployment cost issues, as well as migration options from current solutions.
