The History of Flour Milling in Early America

The water wheel, gears, and bearings made. Some times stone or wood was used for bearings. Stones bearings were lubricated with either water or tallow. Wooden bearings were lubricated with tallow. A dam, mill race and or a sluice box was constructed. Finally the mill was ready to be set into operation. The first grain was ground and the mill ...

What is a Race Condition? | Baeldung on Computer Science

By definition, a race condition is a condition of a program where its behavior depends on relative timing or interleaving of multiple threads or processes. One or more possible outcomes may be undesirable, resulting in a bug. We refer to this kind of behavior as nondeterministic. Thread-safe is the term we use to describe a program, code, or data …

Circular Sawmills and Their Efficient Operation

Figure 1. – Excessively thick or thin lumber reflects inefficient mill operation and is a waste of sawtimber resources. One way to gage a mill's efficiency is to measure its ability to cut lumber consistently within specified thickness standards (fig. 1). Two basic factors affect lumber sizing accuracy: (1) the mechanical capa-

What is a Race to the Bottom? (with pictures)

It may be seen that with the global push towards free trade in the 1990s, labor is now very susceptible to the race to the bottom model. With an extremely large labor pool to draw from worldwide and a virtually unrestricted ability to move capital, multi-national corporations may now freely move their operations from country to country, following the most affordable labor.
