Illmenite sand with steam and hydrochloric acid was handled in the spherical digesters. The temperature in the digesting process was ambient to more than 130°C. Therefore brick lining was applied on a butyl rubber lining 5 mm thick with hardness of 55°A. The rubber serves as a cushioning medium beneath the brick lining, as well as resisting the temperature at the brick rubber interface of about 100°C.

The nucleosome is the fundamental repeating structural unit of chromatin. It is composed of two molecules of the core histones H2A, H2B, H3, H4, approximately two superhelical turns of double-stranded DNA, and linker histone HI (H5). In addition to biochemical studies, the existence of the nucleosome was established in electron micrographs (Fig. la) [1,2], and the name nucleosome, coined to incorporate the concept of the spherical nu-bodies [3]. Micrococcal nuclease limit digestion of chromatin established the nucleosome core particle (NCP) as the portion of the nucleosome containing only the core histones surrounded by 1.75 superhelical turns of double-stranded DNA [4,5].

Eberthella typhosa. The polysaccharide obtained by the hydrolysis of the complex bacterial antigen, isolated from the bacterial cells by tryptic digestion,104 has been examined in the ultracentrifuge byPhilpot.106 Diffusion measurements were not carried out, but assuming that the molecule was spherical, the sedimentation constant (S20 = 1.2(10) 13) indicated a molecular weight of about 10,000 (60 hexose units). The polysaccharide was found to be relatively homogeneous in these measurements. 

The function of lysosomes is intracellular and extracellular digestion. These spherical, membranous organelles contain a group of enzymes called acid hydrolases, which degrade most biomolecules. 

Lipoproteins complexes are soluble aggregates of lipids and proteins that transport lipids through the blood and lymph. Despite their differences in lipid and protein composition, all lipoproteins share common structural features, notably a spherical shape that can be detected by electron microscopy. The lipoproteins help maintain in solubilized form some 500 mg of total lipid per 100 mL of human blood in the postabsorptive state, after the contents of a meal have been digested and absorbed into the bloodstream. 

J. Stone I think there are no basic differences at all. Actually our dextrans are not crosslinked but similar to the P.E.G. s in that they are long chain molecules which randomly coil in solution to form spherical molecules. One reason we prefer the sugars and dextrans is that they are optically active and thus we can use a precision polarimeter for measurement of concentration. We also have a very wide range of molecular sizes. The dextrans have been well characterized by the physical chemistry group at Uppsala and we use the data which we get from them. As far as our basic conclusions are concerned, I don t think there is any dispute at all. We both agree that wood isn t digestible because the pores in wood are too small for the enzyme to get in. ...
