A modification of the Polish Standard Minimum 16 × 16 grid was used to obtain density estimates. Eight assessment lines were used to evaluate the area of effect around the grid. Mammals were removed ...

A common question arises: can density be determined using the free space measured on a gas adsorption analyzer, rather than a device specifically designed for density measurement? This article ...

What’s the average density of the universe? One look out at the night sky will confirm that space isn’t a dense place — but still, its actual density could affect everything from the way it’s shaped ...

THE accurate measurement of crystal density has recently acquired increased importance, since it is necessary to know this quantity in order to use X-ray methods for determining the molecular weights ...

I HAVE just seen in the report of the proceedings of the Physical Society (NATURE, January 15, p. 260) the account of the ingenious and very important experiments proposed by Drs. König and Richarz to ...

The problem of how many identical-sized spheres can be randomly packed into a container has challenged mathematicians for centuries. A team of physicists has come up with a solution that could have ...

Trail camera surveys are a great tool that provide a wealth of information about white-tailed deer and other wildlife on your property. You can gather information about deer population density, doe-to ...

Measuring density is crucial in manufacturing many of today’s products. Being able to characterize the structure and quality of solid materials quickly and efficiently can not only help guide ...

Routine bone density scans already performed on Australians to identify their risk of fractures could now also be used as an early warning for heart attack or stroke. Researchers from Edith Cowan ...
