Thus, the density of transport infrastructures is a good indicator of the intensity of human activities and their impacts on biological diversity, and can be taken as a proxy for general disturbance levels (e.g., Wilkie and others 2000; Sanderson and others 2002; Hawbaker and others 2006; Theobald 2008; Laurance and others 2009).
An increasing velocity spread will not only change the ratio between the main peak and the side peaks, but also significantly decreases the total number density of molecules transported through the decelerator.
The model is based on the principle of mass conservation of coal density layers transported in the jig's bed.
Harvested biomass of low bulk density is transported to integrated large factories for pretreatment under acid or alkaline conditions to degrade the structural carbohydrates.
In principle, all seriously injured patients in the region centred around the city of Utrecht, a region with a population of 1.1 million at a density of 813 inharetransportedare toansporthisto thospitalital.
The presence of clasts in the middle or upper parts of sandstones indicates the viscosity and density of the transporting fluid, which was able to support mudstone clasts and allow grains to deposit via freezing en masse and without grading.
Concentration profiles in horizontal, turbulent pipe flow at a Reynolds number of 50,000 and three nominal volume fractions are presented for each particle species, using experimentally determined acoustic coefficients, in order to isolate the influence of particle size and density on transport and settling in solid-liquid multiphase flows.
Cluster analysis is used to examine the density of facilities and transport spill events as well as test for the spatial covariance between facilities and spills.
To achieve optimal use of transportation infrastructure in general, the bulk density of the material being transported must be such that the containment structure reaches its weight and volume limits simultaneously.
In extant taxa, body mass is an indicator of fundamental ecological and physiological traits such as population density, metabolism and cost-of-transport [ 1].
