Nitrogen use efficiency (NUE) is used to demonstrate the relationship between a soil’s total nitrogen input compared with its nitrogen output. Calculating NUE will give growers a starting point from ...

There are roof shapes and ratios that maximize heat retainment and energy efficiency and, interestingly, ancient Italian architects and builders seemed to know it, too. While serving as a visiting ...

A very inefficient device will waste most of its input energy. The efficiency of a device is the proportion of the energy supplied that is transferred in useful ways. The efficiency can be calculated ...

Devices are designed to waste as little energy as possible. This means that as much of the input energy as possible should be transferred into useful energy stores. A very efficient device will waste ...
