Electric lawn mower in grass-cycling mode. Grasscycling is a method of handling grass clippings by leaving them to decompose on the lawn when mowing.The term combines "grass" and "recycling", and had come into use by at least 1990, [1] as part of the push to reduce the huge quantities of clippings going into landfills, up to half of some cities' summertime waste flow, [2] as 1,000 square feet ...
A variant of the metric perm is used in DIN Standard 53122, where permeance is also expressed in grams per square meter per day, but at a fixed, "standard" vapor-pressure difference of 17.918 mmHg. This unit is thus 17.918 times smaller than a metric perm, corresponding to about 0.084683 of a U.S. perm.
The single probe method employs a heat source inserted into the soil whereby heat energy is applied continuously at a given rate. The thermal properties of the soil can be determined by analysing the temperature response adjacent to the heat source via a thermal sensor. This method reflects the rate at which heat is conducted away from the probe.

A report on proposed changes to U.S. dietary guidelines suggests encouraging Americans to eat more beans and lentils for protein and less red meat.
The higher the thermal diffusivity of the sample, the faster the energy reaches the backside. A laser flash apparatus (LFA) to measure thermal diffusivity over a broad temperature range, is shown on the right hand side. In a one-dimensional, adiabatic case the thermal diffusivity is calculated from this temperature rise as follows:
