Unfolding rule

Darlington s fold/unfold rule is of this type [17]. 

A technical safety barrier represents technical equipment, whose function it is to arrest the accident/incident evolution so that the next event in the chain will not be realised. The human safety barrier is the suitable people, whose function it is to intervene and arrest the accident/incident evolution so that the next event in the chain will not be realised. The organizational safety barrier is the procedures, rules, guidelines, etc. present, which function to arrest the accident/incident evolution so that the next event in the chain will not be realised. In this thesis the latent conditions and precursors in an unfolding situation are considered to have three possible effects on the safety barriers negative, positive or none at all. 

Fortunately, the number of states that ever become populated is relatively small, even under conditions that maximize the population of intermediates. It is apparent that the folding/unfolding partition function can be simplified so that it includes only those states that are relevant to the folding process. The approach that we have undertaken involves the use of the native conformation as a template to generate partially folded conformations, and to evaluate the Gibbs free energy of those conformations according to the rules described in Section III. 

An a-helix bundle may become a second-order cooperative folding unit if the interaction energy terms are such that the intermediate terms in the partition function become negligibly small [Eq. (14)] and the entire partition function reduces to a two-state partition function (i.e., a partition function of the form 1 + e G/RT). If such is the case, the a-helix bundle will be either completely folded or unfolded. Higher order cooperative folding units can be constructed from lower order ones following the same rules. The most immediate application of this approach is to proteins exhibiting pure a-helical structural motifs. 

By integrating the cooperative work perspective to our NATURE based metamodel, we have been able to extend the PRIME process support in order to support the cross-functional interplay among developers. More precisely, PRIME is able to remotely trace the process enactment at several workplaces and transfer information from one to the other, when needed, using a shared ontology that obeys company policies and rules. In order to show the effectiveness of the distributed process support, we have implemented a tool called cooperation console that is able to visualize the workflow of elementary activities of the design process, provide information concerning its execution status, and to unfold the design history for each developer.

The secondary and tertiary structure of a peptide is a function of the primary structure or the amino acid sequence of the peptide. This fact was established by Christian Anfinsen based on the denaturation or unfolding of an enzyme ribonuclease in the presence of urea and the renaturation or folding of the same enzyme after removal of the denaturing substance, i.e., urea. It is important to understand the secondary structure of a protein as a prelude to understanding of the tertiary structure and the function of proteins. It is important to know the rules that proteins follow to assume a 3D structure because of their roles in cellular function and their manipulation in biotechnology and drug design. 

The mechanism by which the relatively large particles are formed is still a matter of debate. It has been proposed that they are the result of phase separation, presumably between unfolded and native molecules, which leads to small volume elements of a high concentration of denatured molecules, which subsequently form roughly spherical gel particles. Anyway, it has become clear that the particles themselves are not quite rigid and do not (always) consist of closely packed protein molecules. However, other mechanisms cannot be ruled out and the question is far from settled. Nor is it clear why the strands in clear gels can be relatively long and of almost constant diameter. 

Calculating the Jacobian ideal of the following functions in one and two variables having a degenerate critical point x3, + x4, x5, x6, x7, x2y — y3, x3 + y3, (x2y + y4), x2y + y5, (x3 + y4) according to the rules presented in Section A2.2 we conclude that the above functions are /c-deter-mined, because their codimension is finite. Furthermore, on the basis of the form of Jacobian ideal we establish that the respective universal unfoldings of these functions have a form consistent with the functions compiled in Tables 2.2, 2.5 (in Section A2.2 we computed the Jacobian ideal, among other functions, for the functions x, x2, x3, x4,..., and for x3 + y3, x2y + y4).
