Dear All,
Do you know whether the densities (or specific gravities) of the
following materials have been measured?
I would be grateful, could you help with values and/or references for:
* Abductin
* Aorta (= Artery in general?)
* Artery (= Aorta?)
* Bladder
* Bryozans
* Cellulose microfibrils
* Cervix
* Cornea
* Echinoids
* Egg shell
* Elastin
* Esophagus
* Feather
* Haversian System
* Horn
* Laminar bone
* Leaf bundle
* Ligament
* Prostrate
* Rectum
* Resilin
* Spider Frame Silk (same as Viscid Silk?)
* Wool (1.31-1.32Mg/m^3?)
Cheers and cherio,
Ulrike Wegst
