Stickiness factor

If deprotonation causes a drop in VIK, the first term in the numerator is (W/ )highpH- S, in Eq. (99) is slightly different from S, the stickiness factor determined from the isotope partition method, or S, the value from displacement of apparent pAT values in VIK profiles, but to a first approximation will have the same value. See Ref. (J) for a more complete discussion. A recent review gives other examples of determining rate-limiting steps by means of isotope effeets (94). 

The Stickiness Factor is how well your message will stick with your intended audience. This factor involves an understanding of what media style and content your message must have to be remembered and utilized by your employees. Your message must be designed and presented so that employees understand and can demonstrate their knowledge of the content (Gladwell, 2000). 

It practice it is usually difficult to establish the reasons for failure as a number of factors may be simultaneously responsible, such as (n) application of the protective to dirty surfaces, (b) carelessness in application, (c) inherent inadequacy of the material, (rf) exposure to unreasonably severe conditions, (e) inevitable difficulties in application. Point (c) includes inadequacy not only in protective properties but, in the case of the hard-film materials, in certain physical properties, e.g. the film may become brittle and flake when handled, may remain too sticky and become contaminated with dirt or adhere to the... 

Two factors have militated against its application — first, the tendency of atactic PVN to flow when mixed with other materials, and second, the inherently sticky nature of atactic PVN pro-pint blends, leading to problems in the extrusion or molding of propint grains...

As enzymatic oxidative transformation of the PVA polymer can act as a multiple simultaneous event on the polymer with concurrent chain fission by the appropriate enzymes, the polymer can be broken down into small oligomers that can be channelled into the primary metabolism. This picture is not complete because PVA is usually more or less acetylated. The DH is a pivotal factor in almost every aspect of PVA application. Surprisingly there are very few data dealing with the enzymes involved in the deacetylation of not fuUy hydrolysed PVA polymer. In technical processes, esterase enzymes are widely applied to deal with PVAc structures. A good example is from the pulp and paper industry [85], where PVAc, a component of stickies , is hydrolysed to the less sticky PVA. Esterases from natural sources are known to accept the acetyl residues on the polymer as substrate but little detailed knowledge exists about the identity of acetyl esterases in the PVA degradative environment [86]. 

Third, there is a need to determine the underlying cause since this may be on an inherited basis described as thrombophilia where all family members need to be investigated. Experience and access to a superior haemostasis laboratory is needed. Defects may extend from hyperhomocysteinaemia through sticky platelet syndrome to mutations of factors V and II or reduced levels of the naturally occurring anticoagulants. Treatments differ and more than one abnormality in what is known as genetic coexpression may co-exist. Correspondence acquired lesions may reflect environmental influences. 

Since dampness is a Yin pathogenic factor and has a heavy, turbid and sticky nature, herbs and formulas should have a steady and constant action. Large dosage should be avoided in a long treatment course. 

Sweet and cold herbs with a sticky and cloying nature should not be used in the syndrome of external dryness as they may hold onto the pathogenic factors. 

After an iPP particle reached the FBR, co-polymerization of ethylene-propylene starts preferrably inside the porous PP matrix. Depending on the individual residence time, the particle will be filled with a certain amount of ethylene-propylene rubber, EPR, that improves the impact properties of the HIPP. It is important to keep the sticky EPR inside the preformed iPP matrix to avoid particle agglomeration that could lead to wall sheeting and termination of the reactor operation. Ideally a "two phase" structure, see Fig.5.4-3, is produced. Finally, a "super-high impact" PP results that contains up to 70% EPR. How much EPR is formed per particle depends on three factors catalyst activity in the FBR, individual particle porosity, and individual particle residence time in the FBR. All particle properties are therefore influenced by the residence time distribution, and finally, a mix of particles with different relative amounts of EPR is produced - a so called "chemical distribution" see, for example, [6]. 

One major consequence of the Ml project was the development of a modified filament stretching instrument by Sridhar. In this device, the test sample is held horizontally between two Teflon discs and pulled equally at both ends at a programmable exponential rate such that a constant strain rate is achieved and the stress growth at a constant stretch rate is obtained (40). It appears though that the test sample has to adhere to the plates as the technique does not use aids to clamp samples. Consequently, it is not clear if the technique can be applied to products that are non-sticky or exhibit slip, which could be limiting factors for testing food products. 

Food rheology is mainly concerned with forces and deformations. In addition, time is an important factor many rheological phenomena are time-dependent. Temperature is another important variable. Many products show important changes in rheological behavior as a result of changes in temperature. In addition to flow and deformation of cohesive bodies, food rheology includes such phenomena as the breakup or rupture of solid materials and surface phenomena such as stickiness (adhesion).
