Nevertheless, the power production
per unit area of land is not particularly impressive.
We see great cultural diversity and large numbers of cultures
per unit area in regions of the world in which the environment is really rich.
Pressure is
force per unit area and work, which has units of energy is defined as force times distance.
Soon enough, we'll have to find new ways to increase food
production per unit area to keep up with an ever expanding population.
Yield is the mass of grain
harvest per unit area harvested — in other words, the productivity of the crops on an area basis.
If the surface temperature of the sun is 5800 K and if we assume that the sun can be regarded as a black body the radiation
energy per unit area can be expressed by modifying (1) to
A Giant Galactic Ghost Intrigued by faint blurs on old photographic plates of the Virgo galaxy cluster, a nearby region teeming with galaxies, Oregon's Bothun and colleagues wondered if the apparitions might be smallish galaxies with «low surface brightness» — astronomer - speak for emitting less
light per unit area than typical galaxies.
Additional escalation of the mining impact occurs as conventional oil mining is supplanted by tar sands development, with mining and land disturbance from the latter producing land use - related greenhouse gas emissions as much as 23 times greater than conventional oil production per unit area [152], but with substantial variability and uncertainty [152]--[153].
The epiphyseal spongiosa of rapidly growing dogs of the larger breeds is inherently less dense and less
strong per unit area than epiphyseal spongiosa of dogs from the smaller breeds.
It is a measure of the stocking of a stand of trees based on the number of
trees per unit area and the diameter at breast height of the tree of average basal area,
Traditional rustic shade has a larger carbon footprint than commercial polyculture because yields are
lower per unit area, and all the contributing factors are allocated to less product.
«Comparing results with other global estuaries, the
discharge per unit area of the Sydney Harbour provides a predictor of emissions for estuaries from a similar geomorphic class,» he said.
The trend has put smiles on the faces of conservationists, who say that large reserves are the fastest way to bulk up protected areas, and are cheaper to
manage per unit area than smaller ones to boot.
One of the major problems with biofuels that algae could solve is space, since algae can yield as much as 100 times more
fuel per unit area than other so - called «second generation» biofuel crops (e.g. non-food crops or non-food waste parts of food crops).
Though it is not a perfect food, maize could feed more
people per unit area than anything else that was available, and populations increased as much as fifteen-fold.
In contrast, the ostrich is the 10th most distinct species, but as it has a large range only 0.05 million years would be
preserved per unit area.
This easily constructed electrode, surprisingly, had an average output of the circuit of 2.24 A m - 2 (
amps per unit area), compared to 0.94 A m - 2 with the felt anode.
So - called prescribed burnings prevent or reduce wildfires, and they appear to produce far less
pollution per unit area than wildfires, the study said.
The similar H2O fluxes
per unit area found in the four giant planets and Titan (Feuchtgruber et al. 1997; Coustenis et al. 1998; Moses et al. 2000), combined with the rather constant dust flux (∼ 3 × 10 − 18 g cm − 2 s − 1) measured in interplanetary space beyond 5 AU (Landgraf et al. 2002), have been regarded as evidence that micrometeoroids — interplanetary dust particles (IDPs) or interstellar — are the dominant source (Moses et al. 2000).
Its colour and spectrum correspond roughly to spectral type A, with a surface temperature of about 25,000 K. Hence, the energy
emission per unit area from the surface must be much greater than that of the Sun.
PD - L1 expression is then measured within each compartment within the tumor mask, and each spot is assigned a score based on pixel
intensity per unit area.
The solar constant is the amount of power that the Sun
deposits per unit area that is directly exposed to sunlight.
Nevertheless, it is important to note that measuring PCSA allows a better estimate of muscle fiber specific tension in vivo than ACSA, as changes in pennation angle obscure the underlying force
per unit area within the muscle (Morse et al. 2008).
You can preheat your water by using a hybrid system to use waste heat from the panels and / or in a seperate portion of roof space — water heating panels are much less
costly per unit area and in terms of energy, but they are not of much use for electrical production; hence the need for other things.
(The unit area that the flux goes through is perpendicular to Q2, while intensity in direction Q1 is
given per unit area perpendicular to Q1; a unit area facing Q2 will appear to have a smaller area in direction Q1 in proportion to cos (θ)-RRB-
There could also be some such complexity in the radiative flux
per unit area absent CO2, which would affect the relationship between changes in CO2 and radiative forcing; for sufficient self - similarity of finer scale texture, the effect might be treated the same way as the texture of the CO2 spectrum -LRB-?).
Absent emission, absorption, reflection, scattering, and refraction outside of a sphere with radius 1, and assuming steady state, the flux coming out of such a sphere is the same as the flux coming out of any closed surface enveloping that sphere; the area of a sphere is proportional the square of the radius, so the average flux
per unit area going through successively larger spheres follows an inverse square law.
