Recent research suggests that extraordinary combinations of strength and ductility can be achieved in the so–called δ–TRIP steels, which contain ferrite, bainite and austenite. A part of the reason for the ductility of almost 40% elongation at a strength of some 900MPa, is believed to be the optimal stability of the austenite to plastic deformation. We demonstrate here that mechanical stabilisa...

Abstract Land surface models are used to provide global estimates of soil organic carbon (SOC) changes after past and future change land use (LUC), in particular re-/deforestation. To evaluate how well the capture decadal-scale SOC LUC, we first consistent comparison simulated time series LUC by six all which participated coupled model intercomparison project phase 6 (CMIP6) with chronosequence...

In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, ...

This article presents a life cycle assessment of bio-based polyethylene terephthalate (PET) bottles with cradle to grave scope and provides comparison petrochemical PET for 13 environmental impact categories. Besides the baseline bottles, which are produced from Brazilian sugarcane reflecting status-quo, two alternative hypothetical product systems were considered: European wheat straw crops ma...

OBJECTIVES It was suggested that glucocorticoid exerts cell-specific effects on thyrotropin-releasing hormone (TRH) gene expression at the transcriptional level. Although there is no typical palindromic glucocorticoid response element (GRE) on the rat TRH gene promoter, a perfect GRE half-site is found between -205 bp and -211 bp. We investigated whether the segment between -242 bp and -200 bp ...

Landslides pose a great threat to the safety of people’s lives and property within disaster areas. In this study, Zigui Badong section Three Gorges Reservoir is used as study area, land use (LU), change (LUC) band math (band) factors from 2016–2020 along with six selected commonly are form factor combination (LUFC), (LUCFC) (BMFC). An artificial neural network (ANN), support vector machine (SVM...

We describe public key cryptosystems and analyse the RSA cryptosystem, pointing out a weakness (already known) of the RSA system. We define Lucas functions and derive some of their properties. Then we introduce a public key system based on Lucas functions instead of exponentiation. The computational requirements of the new system are only a little greater than those for the RSA system, and we p...

In the nineteen eighties, a lot of ink was spent on the question of symbol grounding, largely triggered by Searle’s Chinese Room story (Searle,1980). Searle’s article had the advantage of stirring up discussion about when and how symbols could be about things in the world, whether intelligence involves representations or not, and what embodiment means and under what conditions cognition is embo...
