In this paper we present the first biclique cryptanalysis of MIBS block cipher and a new biclique cryptanalysis of PRESENT block cipher. These attacks are performed on full-round MIBS-80 and full-round PRESENT-80. Attack on MIBS80 uses matching without matrix method and has a data complexity upper bounded by 252 chosen plaintext where it reduced security of this cipher about 1 bit. Attack on PR...

In 1997 the author published an article on vertical full (and ground plane type half) wave loops for 80 meter DX. In that article it was noted that perpendicular (horizontal) polarization is the preferred polarization, particularly at low elevation angles, since horizontally polarized waves are hardly affected by the finite conductivity of the ground in front of the antenna. An exception when v...

in this study formation and properties of o/w emulsion stabilized by a mixture of sodium caseinate (2, 5 and 10 wt %) and non-ionic emulsifier tween 80, sorbitan mono-9-octadecenoate, (0, 0.5, 1 and 1.5 wt %) were investigated at various ph values(3, 5 and 7) and calcium ion concentrations (0, 0.2, 0.4 and 0.6 wt%). emulsion samples were prepared by using a sonicator with a nominal power output...
