Are you looking for a training buddy to prepare your next marathon race? Have ever considered that father could be the right person? Would not it great cross finish line side by and get on podium together? You probably think is young enough such an effort, do you? We believe may also capable of exceptional physical performance, despite his older age. In this article, will see how son (with 25-y...

Cryogenic treatment can be used as a supplemental treatment that is performed on some tool steels between quenching and tempering as an effective method for decreasing retained austenite and increasing wear resistance. In this research, the effect of deep cryogenic treatment (DCT) on dimensional stability and mechanical properties of 80CrMo12 5 tool steel was investigated. The martensitic trans...

Hirsch et al., [1], have outlined for the US DOE the requirements to start countermeasures 20 years before the peak of global oil production. This is in line with the Noah analogy presented at the first ASPO workshop [2]. It is best to finish the ark before the flood. Western Australia's Minister for Planning and Infrastructure, Hon. Alannah MacTiernan has said "It is also certain that the cost...

This chapter describes the separation mechanisms used for DNA electrophoresis. The focus is on the concepts that may help the researcher understand the methodology, read the theoretical literature, analyze experimental data, identify the relevant separation regimes, and/or design optimization strategies. But first, let’s look at some key definitions. Since capillary electrophoresis (CE) is a “f...

A total of 312 samples in two experiments were analyzed to determine mean nutrient concentrations of swine lagoons and hoop barns in Kansas. First, in a retrospective study (Exp. 1), we obtained 41 sample analyses from the Kansas Department of Agriculture of sow, nursery, wean-to-finish, finish, and farrow-to-finish operations in 1999. The average total N concentration was 899 ppm (SD = 584 ppm...

Burnishing is cold working process where hard roller are being pressed against irregular surface, so that surface finish and the micro hardness increases. In this study internal roller burnishing tool is used to burnish the drilled hole. Speed, feed, and number of passes have been varied using taguchi method to examine the surface finish and microhardness. Anova analysis is carried out. Surface...

Today, importance of flexibility and reconfigurability needs to be addressed when designing and implementing a cost-effective and responsive manufacturing system. Such a system should be able to accommodate dynamic changes of product varieties and production volumes by maximizing its production capability and minimizing its production costs, this is particularly useful for a SME (small and medi...

Typical semiconductor production is re-entrant and hence requires priority decisions when parts compete for production capacity at the same machine. A standard way to run such a factory is to start to plan and to finish according to demand. Often this results in a push policy where early production steps have priority over later production steps at the beginning of the production line and a pul...

Parallel reductions represent a common pattern for computing the aggregation of an associative and commutative operation, such as summation, across multiple pieces of data supplied by parallel tasks. In this paper, we introduce finish accumulators, a unified construct that supports predefined and user-defined deterministic reductions for dynamic async-finish task parallelism. Finish accumulator...

objectives : marginal adaptation is important for long-term success of full-coverage restorations. the aim of this study was to determine the effect of porcelain firing cycle and different thicknesses of ips e.max core on marginal accuracy of all-ceramic restorations. materials and methods : a standard stainless steel die with 0.8 mm classic chamfer finish line and 10° taper was used in this in...
