Research on imaging detection of RF leakage on the surface of spacecraft
The determination and locating of leakage point is very important to shielding effect evaluation and solving EMC problem of spacecraft. A RF leakage detection method by near field scanning imaging is presented. The electromagnetic field distribution on the surface of spacecraft can be deduced from one on the plane at some distance to the surface of spacecraft with the convolution relation between electromagnetic field distributions on two parallel planes. The imaging of RF leakage point can be obtained by the method. The effect to imaging of measurement parameters is evaluated by simulation.
Fundamental models for near-field shielding
Models for fundamental shielded enclosures are developed. The models clearly show the dependence of the emissions from the shielded enclosure on the nature of the basic source of emissions within the enclosure. The models serve to clarify aspects of Schelkunoffpsilas approach to shielding analysis which are often questioned.
Women's health in prison: urgent need for improvement in gender equity and social justice.
The needs of women held in detention have received little attention and con-tinue to be neglected by health systems and prison authorities. One reason for this, too readily accepted until now, is that women prisoners are a clear minor-ity group within prisons all over the world. It is only recently that attention has been drawn to the fact that a minor-ity status does not justify the widespread ignorance of women’s basic rights and the considerable gender insensitivity still dominating criminal justice systems.In Europe alone, there are about 100 000 women and girls in prison.
