If we only have interstitial and substitutional diffusion, then what do we consider the process of carburization to be ?
Because in that case we have two objects, one with high concentration of carbon and the other we will diffuse the atoms to it. So, it is not interstitial or substitutional or I did not understand very well?
Homework Answers
Lets start with the origin,
A point defect is a structural imperfection which is of many types , one the type is when impurity atoms are added in a substance then it can be substitutional or interstitial impurity. Substiutional impurities are bigger than parent atom and Interstitial impurity is smaller than the parent atom. Here in carburization carbon atom act as an interstial impurity which diffuses into iron as the size of carbon atom which act as impurity is very small compared to the atom of iron.

What do we look at to consider causality, after we have considered the role of chance (chapter 7), bias and confounding? Understand which each one is and what they mean. You do not have to be concerned with the caveats listed in each slide. Pay particular attention to temporality, the strength of the association(aka the effect measure), dose-response relationship and biological plausibility.

Consider a nanotube made of carbon atoms. What value do the inner and outer radius have if : - The specific surface area is 230 m²/g. - The outer radius is twice the inner radius. - The tubes are open so that the area is the sum of the inner and outer surfaces.

If a portfolio's investment process remains reasonably stable through time, we can predict that the expected tracking error going forward will be approximately the same as that realized in the past. If the fund's process changes or we do not have much historical data, we need to do a different type of analysis, such as the type done with forward- looking risk tools like one of those provided by Northfield, BARRA, etc. Unfortunately, we cannot predict "alpha" as well. True...
