  • steep
  • A steep density gradient in a body of water can have the effect of trapping energy and preventing convection, such a gradient is employed in solar ponds. (wikipedia.org)
  • Energy Density
  • The calorie density (or energy density) of a food is a measurement of the average calories per weight (gram or ounce) of that food. (calorieking.com)
  • Energy Density and Nutrition in Weight Control Management. (calorieking.com)
  • Energy density is the amount of energy stored in a given system or region of space per unit volume. (wikipedia.org)
  • Energy per unit volume has the same physical units as pressure, and in many circumstances is a synonym: for example, the energy density of a magnetic field may be expressed as (and behaves as) a physical pressure, and the energy required to compress a compressed gas a little more may be determined by multiplying the difference between the gas pressure and the external pressure by the change in volume. (wikipedia.org)
  • An extended version of this table is found at Energy density#Extended Reference Table. (wikipedia.org)
  • In energy storage applications the energy density relates the mass of an energy store to the volume of the storage facility, e.g. the fuel tank. (wikipedia.org)
  • The energy density of a fuel per unit mass is called the specific energy of that fuel. (wikipedia.org)
  • Coal, gas, and petroleum are the current primary energy sources in the U.S. but have a much lower energy density. (wikipedia.org)
  • Energy density (how much energy you can carry) does not tell you about energy conversion efficiency (net output per input) or embodied energy (what the energy output costs to provide, as harvesting, refining, distributing, and dealing with pollution all use energy). (wikipedia.org)
  • fracture
  • A bone density test can help determine a diagnosis early, before a person has a bone fracture and can help determine the effects of treatment. (nationaljewish.org)
  • The test measures the bone density in your heel, and is very useful for assessing your risk of fracturing (breaking) your legs, arms, hips and wrists - common fracture sites for sufferers of osteoporosis. (ox.ac.uk)
  • Determination
  • The methods described in this article facilitate determination of sequencing depth in the context of empirically defined read depth to achieve desired marker density for genetic mapping studies. (genetics.org)
  • Examples
  • Note that this option does not produce densities for all of the excited states in a CI-Singles calculation, only the density for the state of interest (see the examples below for a method of doing the former). (gaussian.com)
  • More examples illustrating the use of density estimates for exploratory and presentational purposes, including the important case of bivariate data. (wikipedia.org)
  • Lower
  • If your bone density is lower than normal, you can increase it and your strength. (webmd.com)
  • As a rule the density of neurons is lower in larger brains, a fact which is explained in a qualitative way by the larger size of the neurons in the larger animal (see chapter 34). (springer.com)
  • The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. (wikipedia.org)
  • Spoken texts tend to have a lower lexical density than written ones, for example. (wikipedia.org)
  • If the density exists, the upper and lower densities are equal. (wikipedia.org)
  • Provided that any ball of the Euclidean space intersects only finitely many elements of the packing and that the diameters of the elements are bounded from above, the (upper, lower) density does not depend on the choice of origin, and μ(Ki∩Bt) can be replaced by μ(Ki) for every element that intersects Bt. (wikipedia.org)
  • tend
  • Density altitude is the reason airplane accidents tend to cluster around mountain resorts during the summer months. (everything2.com)
  • In those with a low knot density (as well as kilims), simpler, rectilinear, motifs tend to prevail. (wikipedia.org)
