Planck Finale

"Not by chance, but by truth, what though..."
King John

Planck goes on with further calculations to verify what would be intuitively obvious, that different compositions of the nano materials yields differing strength calculations depending on particular makeup scenarios. E.g. 100% calcified material might be stronger than 30% mineral-70% collagen in one sense and weaker in the next. i.e. as our equine cannon slams into the ground at speed 100% calcified might better withstand a concussive force emanating from the ground but be weaker in face of a sheer force from a bad step.

Said another way, Planck obviously takes a snap shot of material at given points in time and their calculations will of course vary as the make up and composition of the materials vary.

And thus, Planck calculates different strength scenarios depending on composition, states that their method would also work for the larger structures, but that their project will be limited before they go on to calculate scenarios e.g. for osteon structures. They have given us a method.

In the most general sense, Planck stands for the importance of calcification, mineralization, ossification, whatever we're to call it, regards FR (fracture resistance), but, also a whole lot more, in that they detail the function and development of these nano structures so that there is now scientific basis to make further observations.

But, may we take the Planck model's seriously, for, after all, the modeling photo appearing at top of last post in terms of the exterior mineral coating looks very little like this image taken by Paul Hansma with his Atomic Force Microscope:
There are extrafibrillar mineral blobs, to be sure, but where are the patterns? Be assured, they are there. The above image is too small to see them, and we need look at the same image enlarged at 100nm. To see the obvious patterns you will have to click on the below link from Hansma and scroll down to the bone images. At higher resolution of 100nm the exterior mineral fibril coating patterns postulated by Planck are obvious:

What then may we take from Planck that assists in determining "frequency" of speed work necessary to develop and maintain FR?

We look again at what occurs at the nano level as our horse motors down the track. I'd postulated the effects in terms of:

rearrangement of materials
temporary increases in bone glue proteins
temporary compaction of the mineral lattice that will rebound over time unless reinforced by subsequent speed work

all to create density and strength.

I thereafter realized the need to consider the role of mineralization or the question whether equine speed work might possibly stimulate additional mineralization that might create further improvement in FR.

Planck obviously answers this question. Mineralization is of crucial importance in these calculations, but how may this be quantified in terms of how frequently speed work is required? Planck stops short of answering the question and contains some info that the mineralization processes and what stimulates them are as yet unknown. I'll look at this important question, next post.

Training:
Sunday 1/31: Off more due to the trainer then the weather, though the ground is still hard as a rock.
