In the endogenous respiration concept the biodegradable fraction of X OHO is regarded as a homogenous substrate that undergoes self-destruction in the absence of external substrate. The degradation process of X OHO is modelled with Eq. (4) and Eq.xperimental evidence for the validity of the endogenous respiration model comes from Marais and Ekama (1976) . Using the OUR method, the value of b OHO was found to be 0.24 d â1 and independent from SRT in the range of 2.5â30 days. Similar results were obtained by van Haandel et al.
1 Basal cells: These cells are in the lower part of the epidermis, called the basal cell layer. 2  These cells constantly divide to form new cells to replace the squamous cells that wear off the skinâs surface.3  As these cells move up in the epidermis, they get flatter, eventually becoming squamous cells.he main types of cells in the epidermis include: 1  Squamous cells: These are flat cells in the outer part of the epidermis that are constantly shed as new ones form. 2  Basal cells: These cells are in the lower part of the epidermis, called the basal cell layer.
Differences in processes of olfactory and gustatory basal cells. 1) The time it takes a basal cell in the olfactory epithelium to develop and emerge as a mature receptor cell (25-30 days) is longer than in the gustatory epithelium 2) Unlike taste receptor cells, olfactory receptor cells are true nerve cells (neurons).They have a dendritic rod, axon and conduct APs into CNS.)
