Local Government Association (LGA) research suggests that one-in-three councils are worried about the density of fast food outlets.
In Orkney, some organic farmers produce salmon at about half the density of conventional farms, without toxic chemicals or colourings.

Even without legislation, some experts note that women can ask about their breast density, since radiologists routinely report that information to physicians.
The result is a material that has an energy density of about 0.005 watt-hours per kilogram.
"We've appreciated the significance of breast density for probably about 30 years, " Kerlikowske says.
And the density TeraStor bragged about-8.1 gigabits per square inch-is not so impressive anymore.
Current HDDs ship with about 730 Gbpsi maximum areal density.
With HDD areal density growth at about 20-25% annually, down from 40% and higher in past years, manufacturers are looking for ways to increase the storage capacity that they can supply the ever growing digital storage needs of customers.
It's also about packing your recipes with low-density ingredients.
Due to the complexity and cost of the next big technology transitions for HDDs the market is likely to see areal density growth in the range of about 25% annually for the next several years.
GLAS's main job was measuring the height of ice sheets, but the data that came back from forested areas contain a lot of information about the height of the canopy and the density of the vegetation there.

Climatologists say 12 inches of snow is equivalent to about 1 inch of rain, depending on the density of the snow.
Who is supposed to worry about hydrodynamic instabilities initiated at every interface with different density materials, growing an interacting during the implosion and finally causing mix?
"We have been lucky, " says Antiparos mayor Yiannis Leventakis, chatting through an interpreter about the island's auspicious geography and Tsakonas's low-density concept.
Theories about why this is happening range from higher levels of obesity, higher density of calories in processed foods, and physical inactivity, to chemicals in food and water.

The batteries themselves make use of the same zinc air technology used in hearing aid batteries, and apparently have the highest energy density of any portable consumer power solution, which translates to about three times the runtime of a similarly sized alkaline or lithium ion battery.

Built from a box fan, medium-density fiberboard, lexan and aluminum, the tunnel increases airspeed by about 240 percent and cools its contents with a brisk 9 mph breeze.

Sony even admits that the Double Density CD-ROM is a product of the moment that will become about as useful a piece of computer hardware as grandma's sewing machine as soon as read-write capable DVDs are widely available.
In North America, Laki has been blamed for the starvation of Inuit populations from severe cold in northwestern Alaska, based on Inuit oral history as well as tree-ring density data investigated by Gordon Jacoby and others, who estimated that conditions were about 4 degrees Celsius colder than the mean.
The researchers twigged that this phenomenon could be used to measure density and, as they report in the Journal of Agricultural and Food Chemistry, they set about this task by erecting a stack of two off-the-shelf neodymium magnets separated by a vertical vial of paramagnetic fluid.
Note that the actual percentage annual growth in areal density has declined from near 100% per year in the early part of the last decade to about 30% annually today.
