Bone ray branching (as measured by the number of bifurcations) was also altered in NTR+MTZ fish (P<0.03, Fig. 3B), and joint specification (bifurcation position) was unchanged.
Joint specification and tissue patterning are followed by cavitation, where the midline of the interzone transitions from a cell-dense region to a cell-free fluid space.
The molecular programme responsible for joint specification is largely unknown, however, recent efforts have identified a target gene of the non-canonical transforming growth factor-beta (TGF-β) pathway, c-Jun, as an early determiner of synovial joint position, influencing expression of the well-established early molecular marker of the joint interzone, Gdf5.
Studies on embryonic tissues indicate that the activation of the canonical β catenin pathway plays an important role in joint specification [ 30, 42] and in the regulation of chondrocyte differentiation inhibiting chondrogenesis in immature mesenchymal cells and enhancing terminal differentiation in mature chondrocytes [ 29, 32].
A re-examination of the data on which the size effect correction for welded tubular joints in current specifications is based has raised questions about its validity, especially for joints with greater wall thicknesses.
In the footwear industry independently of the type of materials used, to ensure its durability, it is necessary for adhesive joints fulfilling certain specifications defined by EN 20344 (5.2), which establishes the minimum values to consider for difficult bonding.
This paper seeks to address the joint production and quality specification control problem in multiple-product unreliable manufacturing systems.
The model can then be used to formulate at best adhesive materials to optimize the mechanical performance of HBB joints according to work specifications.

The results, based on specification and joint estimation of a conditional revenue function and a production (economic) inefficiency model using the parametric - Stochastic Frontier approach of Battesse and Coelli ([1995]) is presented Table 5.
