Some universities in these four North African countries award a "Doctorate of the State" in some fields of study and science. A "Doctorate of the State" is slightly higher in esteem than a regular doctorate, and is awarded after performing additional in-depth post-doctorate research or achievement. Asia Japan Similarly to in the US and most of Europe, Japanese universities offer both the PhD and the ScD as initial doctorates in science. India In India only a few prestigious universities offer ScD/DSc in science which is obtained in Graduate School after satisfactory evaluation of knowledge, research accomp ...

Salisbury Screen
The Salisbury screen is a way of reducing the reflection of radio waves from a surface. It was one of the first concepts in radar absorbent material, an aspect of "stealth technology", used to prevent enemy radar detection of military vehicles. It was first applied to ship radar cross section (RCS) reduction. The Salisbury screen was invented by American engineer Winfield Salisbury in the early 1940s (see patent filing date). The patent was delayed because of wartime security.. Salisbury W. W. June 10, 1952, cited iMunk/ref> Method of operation Salisbury screens operate on the same principle as optical antireflection coatings used on the surface of camera lenses and glasses to prevent them from reflecting light. The easiest to understand Salisbury screen design consists of three layers: a ''ground plane'' which is the metallic surface that needs to be concealed, a lossless dielectric of a precise thickness (a quarter of the wavelength of the radar wave to be absorbed), and a thin ...
