Study on GP Zones Formation in the Sc Inoculated Ternary Al-Zn-Mg Alloys
Abstract: Mostly, ternary Al-Zn-Mg (7075) alloys are used in automotive and aerospace engineering due to readily age-hardening response and high specific strength-to-density ratio. Scandium (Sc) has great inoculation effect in Al-Zn-Mg alloys. The cast Al-Zn-Mg alloys system undergoes a complex transition sequence in order to gain maximum strength. This sequence consists of solutionizing then immediate quenching in water (T4), natural ageing and artificial ageing (T6); usually, in several temperature steps to …

Comparison of Ultra Wide Band Indoor Multipath IEEE 802.15.3 Channel Model
Abstract: ABSTRACT A very large bandwidth of frequency (3.1–10.6 GHz) has been allocated to UWB systems. A single-band UWB signal propagates differently in the lower and upper bands of the spectrum due to the size of its bandwidth. The lower part of the signal can be obstructed more easily and the man-made interferences are not homogeneously distributed over the whole spectrum. The first experimental results obtained for a UWB channel show …

Qooba (Dermatophytosis): A Review on Myths and Facts Surrounding Fungal Infection of Skin
Abstract: When we hear the word "ringworm", we envision a collection of puny worms slithering around on our skin. Then we may have fallen prey to one of the many misconceptions about this common skin condition. In reality, ringworm is far less creepy than the name suggests. Probably the most pervasive ringworm myth, this one stems from the condition's name. Despite its creepy-crawly name, ringworm (also called tinea) is not caused …
