In recent years, with the rapid economic development of Bohai Economic bay area in China, the atmospheric environmental pollution problem has been of wide concern and has attracted great public attention. In this paper, the data of PM₁₀, SO₂, CO, NO₂, O₃ and PM₂.₅ in 12 cities located around the Bohai Bay area of China were collected in 2016. These 12 cities were divided into coastal and non-coastal...
The prolactin receptor (PRLR) gene was studied as a candidate gene for the high prolificacy of Jining Grey goats. Polymorphisms in intron 1 and intron 2 of PRLR gene were detected in high prolificacy (Jining Grey) and low prolificacy (Boer, Wendeng dairy, Liaoning Cashmere and Beijing) native goats using PCR-SSCP. For intron 1, five genotypes (AA, AH, AK, HH and HK) were identified in Jining Grey...
Many potential applications of mobile ad hoc networks (MANETs) involve group communications among the nodes. Multicasting is an useful operation that facilitates group communications. Efficient and scalable multicast routing in MANETs is a difficult issue. In addition to the conventional multicast routing algorithms, recent protocols have adopted the following new approaches: overlays, backbone-based,...
