The freely-rotating chain improves the freely-jointed chain model by taking into account that polymer segments make a fixed angle to neighbouring units because of specific chemical bonding.

Consider a linear polymer to be a freely-jointed chain with N subunits, each of length, that occupy zero volume, so that no part of the chain excludes another from any location.

A longer, " effective " unit length can be defined such that the chain can be regarded as freely-jointed, along with a smaller N, such that the constraint L = N x l is still obeyed.

An ideal chain ( or freely-jointed chain ) is the simplest model to describe a polymer.

The WLC model envisions an isotropic rod that is continuously flexible ; this is in contrast to the freely-jointed chain model that is flexible only between discrete segments.

A real polymer is not freely-jointed.

The average end-to-end distance for freely-rotating ( not freely-jointed ) polymethylene ( polyethylene with each-C-C-considered as a subunit ) is l times the square root of 2N, an increase by a factor of about 1. 4.

A standard example of an entropic force is the elasticity of a freely-jointed polymer molecule.

otherwise, you'll have to spend a few minutes to either attach a suitable spring clip somewhere on the press head or fit the key to a length of light chain and fasten to the bottom of the motor mount so that the key is out of the way when not in use.

Physicochemical investigations of anionic surfactants, including the soaps, have shown that there is little polymerization or agglomeration of the chain anions below a certain region of concentration called the critical micelle concentration.

Related to micelle formation is the technologically important ability of detergent actives to congregate at oil - water interfaces in such a manner that the polar ( or ionized ) end of the molecule is directed towards the aqueous phase and the hydrocarbon chain towards the oily phase.

If Af leads to an address Af that is equal to the address computed from Af, even though Af does not match Af, the chain of information cells is extended from Af by storing the address of the next available cell in the Y-region, Af, in Af.

The cell Af becomes the second information cell in the chain and is assigned as the information cell of Af.

Each information cell in the chain contains the address of the Y-cell where the form to which it is assigned is stored.

Each cell except the last in the chain also contains the address of the Y-cell that is the next element of the chain ; ;

Hence, when the address Af is computed from Af, the cell Af and all Y-cells in its chain must be inspected to determine whether Af is already in the form list or whether it should be added to the form list and the chain.

In the simplest of the looped stitches, the chain stitch, the needle comes up from the back of the fabric and then the needle goes back into the same hole it came out of, pulling the loop of thread almost completely through to the back ; but before the loop disappears, the needle come back up ( a certain distance from the beginning stitch-the distance deciding the length of the stitch ), passes through the loop and prevents it from being pulled completely to the back of the fabric.

Several competing models, although correctly dealing with the conformation of each individual peptide chain, gave way to the triple-helical " Madras " model, which provided an essentially correct model of the molecule's quaternary structure although this model still required some refinement .< ref > The packing structure of collagen has not been defined to the same degree outside of the fibrillar collagen types, although it has been long known to be hexagonal or quasi-hexagonal.
