Order hardening of platinum alloys
The hardening behaviour of three cold-worked platinum alloys, Pt 5 at% Mo, Pt 5 wt% Ru and Pt 5 wt% Cu, has been investigated through a systematic series of heat treatments. All three of the experimental alloys showed a hardness increase during annealing within a specific temperature range. The …

A partial hardening has come upon Israel: Divine hardening and its implications for Jewish evangelism
This dissertation explores the hardening mentioned in Romans 11:25 and its role in Israel's rejection of the gospel. Chapter 1 describes the difficulties faced when addressing the issue of hardening. Additionally, the thesis states that in the case with the Jewish people, the partial hardening has …

STRAIN-HARDENING AND RATE EFFECTS IN PLASTICITY
In this study the effects of strain-hardening and rate sensitivity in plasticity theory are investigated. Because the method of characteristics cannot be applied to problems involving rate dependent yield conditions (65) therefore a different procedure is developed. In this investigation of large …

Hill reaction and frost hardening in cabbage
"The Problem. How often have men stopped and wondered at seeing plants surviving and struggling against temperature extremes which to all appearances have killed and destroyed other plants next to them? What inherent or developed ability is this that allows some to survive even when ice crystals …

Hardening DGA Classifiers Using Adversarial Attacks and IVAP
Domain generation algorithms (DGAs) are utilized by botmasters as a way to connect malware-infected machines with the botmaster's command-and-control center (C\&C). Such a connection allows the botmaster to send and receive information between his machine and the infected machines at will, which …

Controlled Surface Layer Deposition for Steel Surface Hardening
… 5% H2-N2 (nitridation), were used for surface hardening. The coarse Ti particles (≤50 μm) were suspended in ethanol using the charging agent poly(diallyldimethylammonium chloride) (PDADMAC). EPD: The present work demonstrated the importance of assessing the electrophoretic mobilities of both …

Analysis of a bent constructed from a strain-hardening material
In conclusion, it can be said that the method of approach (whether by the minimum complementary energy or column analogy) is very straightforward, and the final set of equations can be developed very quickly. However, the final simultaneous solution presents a very difficult part of obtaining the …
