The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...

in order to study the effect of row spacing and plant density on quantity and quality yield of soybean in weed competitive condition, a field experiment was carried out at research farm of yasuj agricultural college in summer of 2011. experiment arrangement was split factorial base on randomized complete block design with three replication. the main factor included weed ( in two levels of contr...

Hydrocode simulations were conducted to analyze the non-linear response of 1100-O aluminum plates with semi-circular notches. Plates with constant notch depth and notch root radius were loaded (normal to the notch-tip plane) to the same shock stress while the notch spacing was varied. The resulting stress distributions were analyzed at specific locations between adjacent notches and then the ma...

This study analysed the performance of constant time based airborne spacing under different operational conditions using fast time simulation. The effects of time based spacing criteria, mixed aircraft types and wind conditions on the ability of an aircraft to maintain a time spacing behind a descending lead aircraft were investigated. The spacing performance of a previously used approximate ti...
