Safety climate has also been measured using safety culture maturity matrixes (Ashcroft et al. 2005 Dingsdag et al. 2006, 2008 Hayes et al. 2007, 2008 Kirk et al. 2007). Safety culture maturity matrices display a set of key indicators on the y axis and an evolutionary measure of cultiual maturity on the x axis. Originally developed as part of the Hearts and Minds project for Shell pic, one such matrix, the Manchester Patient Safety Framework (MaPSaF) was adapted for use in primary care settings and has since been developed into versions for mental health, acute and ambulance trusts (Kirk et al. 2007). 

It is formed during collagen maturation, not biosynthesis, and originates only as a breakdown product of mature matrix.

The form of this tool is also a maturity matrix shown in Table 5.7. The Table 5.7 matrix is future oriented, assessing whether or not the skills are available to move to the next level. 

Note that the maturity matrix applies to any project work conducted in the organization, not just supply chain projects. Other project types could include new product development, information systems improvements, facility additions, and incorporating acquisitions into operations. 

Risk Maturity—The organization will work towards meeting its minim risk maturity requirements as defined by its maturity matrix/model. 

The role of yeast in fermenting dough maturation is even less clear. The alcohol and carbon dioxide developed during fermentation must influence the elastic properties of the protein matrix. However, experimental procedures that would permit this to be checked in the absence of yeast have not been developed. 

Osteoblasts are the primary cells responsible for bone formation. They are derived from mesenchymal (stromal) cells that first differentiate into pre-osteoblasts and then into mature, bone matrix producing osteoblasts. Inactivated or resting osteoblasts become lining cells and thus a reservoir for bone forming cells to be activated at the next remodelling cycle. Osteoblasts trapped and embedded in the mineralised matrix are called osteocyts, and are important for many properties of living bone. 

It may be that this fact was associated with the rather complex composition of fungal mycelium, consisting of chitin enclosed in a glucan matrix (Bowman, Free, 2006). Therefore, mature saprophyte mycelium are completely covered by difficult-soluble glucans and the fraction of chitin in the apical cell wall is not sufficient. As such, we supposed that these cationic isoforms bound with another major component of the fungi... 

The Rieske protein in mitochondrial bci complexes is assembled when the protein is incorporated into the complex. The Rieske protein is encoded in the nucleus and synthesized in the cytosol with a mitochondrial targeting presequence, which is required to direct the apoprotein to the mitochondrial matrix. The C-terminus is then targeted back to the outside of the inner mitochondrial membrane where the Rieske cluster is assembled. In addition, the presequence is removed and the protein is processed to its mature size after the protein is inserted into the bci complex. In mammals, the presequence is cleaved in a single step by the core proteins 1 and 2, which are related to the general mitochondrial matrix processing protease (MPP) a and (3 subunits the bovine heart presequence is retained as a 8.0 kDa subunit of the complex (42, 107). In Saccharomyces cerevis-iae, processing occurs in two steps Initially, the yeast MPP removes 22 amino acid residues to convert the precursor to the intermediate form, and then the mitochondrial intermediate protease (MIP) removes 8 residues after the intermediate form is in the bci complex (47). Cleavage by MIP is independent of the assembly of the Rieske cluster Conversion of the intermediate to the mature form was observed in a yeast mutant that did not assemble any Rieske cluster (35). However, in most mutants where the assembly of the Rieske cluster is prevented, the amount of Rieske protein is drastically reduced, most likely because of instability (35, 44).

The enamel of mammalian teeth is much more heavily mineralized than bone, which makes it much harder. In addition, it does not contain collagen, although in its final mature state it does contain small amounts of specialized matrix proteins. Early tooth development is a classical illustration of the interaction between two tissue types (epithelial cells and... 

As they secrete osteoid matrix around themselves, osteoblasts eventually become entrapped within lacunae ( spaces ) and mature into osteocytes. Although topographically isolated from each other, osteocytes maintain contact with neighbours by cell processes which run through tiny interconnecting fluid-filled canaliculi (channels) within the matrix.
