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.
Gustatory cortex. The primary gustatory cortex is a brain structure responsible for the perception of taste. It consists of two substructures: the anterior insula on the insular lobe and the frontal operculum on the inferior frontal gyrus of the frontal lobe. Because of its composition the primary gustatory cortex is sometimes referred to in literature as the AI/FO. By using extracellular unit recording techniques, scientists have elucidated that neurons in the AI/FO respond to sweetness, saltiness, bitterness, a
