according to high costs of phase shifters in antenna arrays, new methods for beam steering without phase shifter were introduced. frequency diverse array (fda) concept is another approach to beam steering problem. in this structure, the subsequent antenna elements are fed with stepped discrete frequencies causing continuous scanning of space in time. so a range-angle dependent scanning is made ...

Administration of nicotine leads to incentive and behavioral tolerance in human and animals. Ascorbic acid administration inhibits some effects of nicotine. In the present study, the effects of ascorbic acid administration on the expression and development of nicotine-induced behavioral tolerance in female Swiss-Webster mice (20-25 g) was investigated. Animals were injected with nicotine (0.5 m...
