This study intends to make clear the effects of the property of base metal, specimen width, sheet thickness and nugget diameter on the initiation life of fatigue crack and the propagation life in ...

The molecular formula and empirical formula of some substances are the same. For example, both types of formula for carbon dioxide are CO 2.

To determine the empirical formula of magnesium oxide. Mass of crucible and lid (step 1) 50.00 Mass of crucible, lid and magnesium (step 3) 50.24 Mass of crucible, lid and magnesium oxide (step 7) ...

Back to basics with today’s graphic, with a look at the different ways compounds in organic chemistry can be represented. Obviously, if you’re a chemist, these will all be second nature, but as was ...

We consider the classical problem of estimating a vector $\mu = (\mu_{1},..., \mu_{n})$ based on independent observations $Y_{i} \sim N(\mu_{i}, 1), i = 1,..., n ...
