In strict usage, density is defined as the mass of a substance per unit volume; however, in common usage, it is taken to be the weight in air of a unit volume of a sample at a specific temperature.
With strict local density regulation (i.e., soft or within-family selection; eqn 5b), the direct effect of an allele will determine its evolutionary trajectory.
Similarly, strict CpG density is unlikely to explain specific methylation of these genes, as the CpG islands associated with both Dazl and Ppp2r2c have a similar observed over expected CpG ratio (0.76, http://www.ensembl.org/Mus_musculus/Info/Index).org/Mus_musculus/Info/Index
At the same time, the city's hilly, canyon-like terrain and significantly long average trip distances brought about by strict low-density zoning laws—somewhat restrict cycling for utilitarian purposes.
In central London's prime neighborhoods, high density, strict building codes and skyrocketing real-estate prices up 43% since March 2009, according to real-estate firm Knight Frank are resulting in some of the most elaborate subterranean living spaces in the world.
In an attempt to boost the market, new legislation was introduced Aug. 4 to relax the regulations requiring residential units at hotels and tourism sites to be approved on an individual basis, with strict controls on density.
Mr Glaeser and Matthew Kahn have also shown that tight land-use restrictions end up pushing Americans out of the country's greenest cities, like those on the California coast, and into the dirtiest, like those in Texas.There are significant hidden costs to strict limits on density, and there is generally no attempt to balance such costs against potential benefits when zoning rules are set.
Of course, I'm not talking about a strict count of melanin density.
In recent years, the requirements for non-volatile become more and more strict in the storage density, operation speed, and power consumption [1 7].
In addition, determining drill resistance may be the only form to collect data on wood density in strict forest reserves, where the collection of stem discs is not permitted.
