As some commentators have pointed out, the public interest is an ancient and new topic. It＇s a highly abstract prone to ambiguities and shortcomings of the concept. And it＇s also a basket that strange, confused and can not be discarded. Even critics simply deny the existence of public interest and regard the public interest as a myth. As it＇s difficult to define the public interest from political perspective, a democratic theory, legal perspective a theory of law, economic perspective a public choice theory, philosophical perspective a public philosophy, and other common perspective. The paper explores the law theory of public interest from the framework of the overflow theory and the perspective of the concept function, and provides an easy to use identification method of public interest for the judicial practice and administrative practices.展开更多

Three farmlands were considered in the course of this study. Two of the three farmlands were within the Ikorigho and Otumara communities that recently experienced oil spillage and they are about 300 m from each other. While the third farm was within the Igbokoda community which is geographically similar but has not experienced oil spillage, it was used as control. The farmland was delineated at each area by the grid technique and soil samples were collected at 0-20 cm depth of the ground. Some physiochemical properties that reflect soil nutrient content and fertility status （pH, electrical conductivity, moisture content, organic matter, nitrogen, phosphorous and cation exchange capacity （CEC）） were determined using standard methods and results from the three areas were compared. There was a significant decrease in the calcium （Ca）, magnesium （Mg）, potassium （K） and organic matter, as well as a significant increase in the electrical conductivity, moisture content and phosphorous content of the oil-spill affected farmlands at Ikorigho and Otumara when compared with the non-affected farmland at Igbokoda. The acidic nature of the farmlands could not be attributed entirely to the oil spill since the control farmland at Igbokoda was slightly acidic. The results show that oil spillage has adversely affected the nutrient level and fertility status of farmland at Ikorigho and Otumara communities, which needs urgent remediation.展开更多

Usually, a finite size buffer is needed at the transmitter to match instant channel capacity with the source data stream. This paper is focused on the queuing process in the buffer. The temporal characteristics of the queueing process in the buffer are investigated, for a buffer-aided communication over block Rayleigh fading channel, in the low signal- to-noise ratio regime. Particularly, the average absorbing time for the buffer to transfer from empty state to overflow sate and from overflow state to empty state, as well as the stable working time in which neither buffer empty nor buffer overflow happens are derived. Theoretical and numerical results show that increasing the buffer size and traffic load properly will improve the efficiency of the transmission.展开更多
