Wireless personal area networks (WPANs) will be major components of the heterogeneous communication environment of the future. The devices in a WPAN must be low cost and operate for a long time from a battery. As a consequence, they pose demanding requirements on the utilized integration technology. In this paper we confront these requirements with the newly released international technology roadmap for semiconductors (ITRS-2001). Power consumption is identified as the key problem, motivating a large research effort in low power design techniques. In addition, it is pointed out that WPAN devices will consist of different technologies, requiring a better design support for mixed-technology integration.

with the continuous expansion of shale gas development in drilling engineering, there are more and more waste oil drilling cuttings, which has become a heavy burden on the oilfield. If not treated effectively, it will cause great harm to the natural and address environment around the oilfield. This paper mainly studies several kinds of waste oil cuttings disposal technology, and puts forward the most mature technology of eight medium oil cuttings disposal at present, in order to help the relevant treatment work.

The need for novel and diverse sources of protein to feed the growing world population is urgent and stark. At the same time, peoples' eating habits and values are also changing, with more consumers considering alternatives to traditional sources of protein. Novel protein sources not only need to provide essential amino acids and nutrition, but also cater to taste, convenience, cost economics, and personal needs. They also need to be ethically produced, with a smaller environmental footprint, and when feasible, closer to consumer. Insect protein has been researched intensively in recent years with promises to best fulfill these needs. As the insect protein field and industry are expanding and getting more mature at this stage, this review summarizes their properties and applications within the context of the food and feed industry. The important functional properties that make insect proteins useful are also discussed.
