A medium Mn steel of composition Fe-4.8Mn-2.8Al-1.5Si-0.51C (wt.%) was processed to obtain two different microstructures representing approaches in the hot rolling mill, resulting equiaxed vs. mixed and lamellar microstructures. Both were found exhibit a simultaneous Twinning Induced Plasticity Transformation (TWIP ? TRIP) mechanism where deformation twins ??-martensite formed independently twi...

TRIP-Br3 and TRIP-Br1 have shown to have important biological functions. However, the function of TRIP-Br3 in tumorigenesis is not well characterized compared to oncogenic TRIP-Br1. Here, we investigated the function of TRIP-Br3 in tumorigenesis by comparing with that of TRIP-Br1. Under nutrient/serum starvation, TRIP-Br3 expression was down-regulated slightly in cancer cells and significantly ...

Nanostructured bainite is a novel ultra-high-strength steel-concept under intensive current research, in which the optimization of its mechanical properties can only come from a clear understanding of the parameters that control its ductility. This work reviews first the nature of this composite-like material as a product of heat treatment conditions. Subsequently, the premises of ductility beh...

Sometime after a trip to New Guinea in 1972, perhaps the world’s most noted ornithologist-physiologist-turnedevolutionary biologist and biogeographer set about “the modest task of trying to explain the broad pattern of human history, on all the continents, for the last 13,000 years.” In 1998, Guns, Germs, and Steel won the Pulitzer Prize. The book’s thesis, in short, is that specific geographic...

This paper addresses the problem of characterizing analytically the autocorrelation structure of TCP traffic. We show that, under simple models, a single TCP connection generates traffic with an exponentially decreasing autocorrelation function. However, several TCP connections sharing a given link can generate traffic with long term dependencies, under the condition that the distribution of th...

This research elucidates the trip pattern of the low-density residential zone in a semi-urban industrial cluster of southwestern Nigeria. These sets of dwellers are often times neglected in the transportation planning process with the view that it is not a residential zone. Domiciliary information gathering procedure was employed in the analysis with 0.82 return rates. It was backed up with the...

In this article, an innovative supervision system will be proposed that can observe and analyze health of Circuit Breaker’s trip coil. The proposed design also logs changes in the coil's quality and informs network supervisor in case of Circuit Breaker (CB) failure. This system injects small direct currents to the Circuit Breaker connections and the trip coil to compute CB’s health and characte...

Abstract Carbon is a well known austenite stabiliser and can be used to alter the stacking fault energy stability against martensitic transformation in medium Mn steels, producing range of deformation mechanisms such as Transformation Induced Plasticity (TRIP) or combined Twinning (TWIP + TRIP) effects. However, effect C beyond quasi-static tensile behaviour less known. Therefore, two steels wi...

This paper considers the popular but questionable technique of ‘round-trip translation’ (RTT) as a means of evaluating free on-line Machine Translation systems. Two experiments are reported, both relating to common requirements of lay-users of MT on the web. In the first we see whether RTT can accurately predict the overall quality of the MT system. In the second, we ask whether RTT can predict...
