Whole grain density

We have seen above that mercury does not spontaneously penetrate the pores of the solid in the absence of pressure. This result is used to measure the volume displaced by the material + pores of a solid as a whole. The apparent density (or grain density) p is then calculated using the following expression ... 

FIG. 7 A food guide pyramid to promote health. Recognition is made of the role of functional foods. The foundation of the pyramid is vegetables, legumes, seeds, nuts, and fruits. Cereal grain products, both whole grain and products with a nutrient density less than 50 calories for nutrient, are moved to the second tier. The foods of the two bottom tiers meet the needs of the vegan. This recommendation also coincides with the majority of health claims data (Table II). 

Whole wheat bakery products are produced in order to provide higher amounts of dietary fiber with proven health benefits. A comparison between white pan and whole breads indicates that the first contains about one-third of the dietary fiber found in whole wheat pan bread (Table 17.8). The consumption of whole grain breads also slightly lowers energy density and it has a lower glycemic index, improving gastroin-... 

Grain yield is dependent on the number of heads per hectare, the number of kernels per head and the size and density of those kernels (9). To maximize yields, every element in the whole production system must be directed towards balancing and optimizing those three contributing factors. In many ways, change in wheat production in the last ten years has been a microcosm of what has taken place in the last forty years of maize production. The changes are similar but have been compressed in time. 

Another viable method to compare experiments and theories are simulations of either the cell model with one or more infinite rods present or to take a solution of finite semi-flexible polyelectrolytes. These will of course capture all correlations and ionic finite size effects on the basis of the RPM, and are therefore a good method to check how far simple potentials will suffice to reproduce experimental results. In Sect. 4.2, we shall in particular compare simulations and results obtained with the DHHC local density functional theory to osmotic pressure data. This comparison will demonstrate to what extent the PB cell model, and furthermore the whole coarse grained RPM approach can be expected to hold, and on which level one starts to see solvation effects and other molecular details present under experimental conditions. 

Sampling Procedures The purpose of taking samples is to record the properties of the whole volume of material from a small, analyzed portion of it. This is difficult to achieve with solids since industrial mixes in particular always present a distribution of grain sizes, shape, or density and can also separate out when samples are being taken, on account of the ingredients specific motional behavior (see the subsection Sampling ). 

It should also be noted that in general, the magnetic density is a vector field, and this would introduce some problems with computational efficiency, since the sizes of matrices would increase. In both the EMTO method and the BGFM, an approximation called the Atomic Moment Approximation is made. This is an approximation where you assume that the spin direction is the same within each atomic sphere. This can be motivated by noticing that the spin density often is centered around the nuclei, and that it is almost collinear around each nuclei [128]. In this way, one can coarse grain the problem, from a big mesh of the whole vector field to a much smaller mesh consisting of only the nuclei.
