This paper gives research results about commercial examination of aluminum alloy-based products according to industrial standards. Results of metallographic tests of extruded aluminum microstructure shown in this paper indice that irregular deformation of material leads to microstructure variations through certain zones of the product. That influences mechanical properties, and it can even be t...

the theorem 12 in [a note on $p$-nilpotence and solvability of finite groups, j. algebra 321(2009) 1555--1560.] investigated the non-abelian simple groups in which some maximal subgroups have primes indice. in this note we show that this result can be applied to prove that the finite groups in which every non-nilpotent maximal subgroup has prime index aresolvable.

We propose to use a mathematical method based on stochastic comparisons of Markov chains in order to derive performance indice bounds. The main goal of this paper is to investigate various monotonicity properties of a single server retrial queue with first-come-first-served (FCFS) orbit and general retrial times using the stochastic ordering techniques.
