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 ...
Cutting grass in southern Tasmania. Gahnia grandis originated in southern Australia. About 40 species are found in Australia, Asia, and the Pacific Islands. [6] The species is found particularly in Western Australia, Queensland, New South Wales, Tasmania, and Victoria, [7] where it is native to areas such as the Gippsland plain, Wilsons Promontory, and Highlands-Southern Fall bioregions.
Given the coarse accuracy of the Blaney–Criddle equation, it is recommended that it be used to calculate evapotranspiration for periods of one month or greater. [ 1 ] The equation calculates evapotranspiration for a 'reference crop', which is taken as actively growing green grass of 8–15 cm height.
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 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.
Operative temperature is used in heat transfer and thermal comfort analysis in transportation and buildings. [10] Most psychrometric charts used in HVAC design only show the dry bulb temperature on the x-axis(abscissa), however, it is the operative temperature which is specified on the x-axis of the psychrometric chart illustrated in ANSI/ASHRAE Standard 55 – Thermal Environmental Conditions ...
The city’s hated new congestion toll could dangerously delay FDNY response times — meaning the “difference between life and death,” unions repping thousands of Bravest warned Sunday. The ...
