There can be many passive intermodulation(PIM) pointsources even in a device or a radio link, which may add up constructively or destructively. A modified point-source model with lossy components is proposed to evaluate the superposition effect of the forward and refl ected PIM in case of series connection. The index of the series connection factor(SCF) is employed for systems that incorporate multiple PIM sources to predict the important characteristics of the cumulative PIM, such as the maximum and minimum values and the limit form. Furthermore, some initial experimental results are given out and the deviation in the above-mentioned prediction is also analyzed.展开更多

The democratic ethos of Pentecostalism declares that all people who feel the call to preach must be given that opportunity which opens a space of women's voices within the traditionally male "preacher culture." Because radio lacks the visual component, and inspired preaching is deemed valid by its effect of the body, women may preach over the radio without the potential for sexual display that could arouse men visually. By examining the content and delivery of women's sermons using studies in melodrama, the article explores the nature and articulation of dramatic conflicts, points of difference, and especially issues of the body as lived by the women of southern Appalachia. Thereby, the article locates sites of resistance and conflicts with power both within and without the region. Using Gramcian notions of hegemony, negotiation and consent, it explores how a particular culture successfully elaborates itself through language and how Appalachian women critique their culture without risk of dramatic change.展开更多
