As it is known [7], in semicrystalline polymers deformation process partial melting-recrystallization (mechanical disordering) of a ciystalline phase can be realized, which is described quantitatively within the framework of a plasticity fractal theory [10]. According to the indicated theoiy Poisson s ratio value Vj, at a yield point can be evaluated as follows ... 

The calculation of a relative fraction of ciystalline phase subjecting to mechanical disordering, can be performed according to the equation [7] ... 

FIGURE 2 The dependence of relative fraction of crystalline phase subjecting to mechanical disordering, on space dimension D for nanocomposites HDPE/MMT. 

It has been shown that at semi crystalline polymers with devitiificated amorphous phase consideration as natural hybrid nanocomposites their anomalous high reinforcement degree is realized at the expense of crystallites partial recrystallization (mechanical disordering), that means crystalline phase participation in these polymers elastic properties formation. It is obvious, that the proposed mechanism is irrapplicable for the description of polymer nano composites with inorganic nano fillers. 

For amorphous glassy polymers it has been shown that % value is equal to a relative fraction of loosely packed matrix (Pj In case of semi crystalline polymers in deformation process partial recrystallization (mechanical disordering) of a crystallites part can be realized, the relative fraction of which is determined by the following equation [5] ... 

Thus, the performed estimations demonstrated, that high values of reinforcement degree EIE for semi crystalline polymers, considered as hybrid nano composites (in case of studied HDPE EIE value is varied within the limits of 10-110) were due to recrystallization process (mechanical disordering of crystallites) inelastic deformation process and, as consequence, to contribution of crystalline regions in polymers elastic properties formation. It is obvious, that this mechanism does not work in case of inorganic nano filler (e.g., organoclay). Besides, a nano filler... 

The parameter % in the Eq. (4.9) characterizes a polymer fraction, which does not participated in plastic deformation process, but subjects to elastic deformation. For semicrystalline pol5mier this fiaction consists of devitrificated amorphous phase and crystalline phase part, which was subjected to partial mechanical disordering [4]. In other words, the parameter % characterizes he deformed polymer structural state. For the considered in Refs. [2, 3] HDPE crystallinity degree K= 0.687 and, hence, amorphous phase fraction (p, makes up 1 - = 0.313. As estimations according to the Eq. (4.9),... 

In Fig. 10.1, the relations of the values and tpj, (Xcr 9im) adduced for HDPE samples within the range of 7 = 293 -s- 353 K. As one can see, the increase of any from the indicated structural components results to T j growth, but the relation 1 1 was obtained only for (5 + This relation of complete energy dissipation is typical for rubbers, which is both devitrificated loosely packed matrix with fraction cpj and mechanically disordered crystallites part with fraction x - Hence, the indicated structural components of deformed state define energy dissipation in HDPE, but not amorphous phase itself, the part of which (clusters) does not participated at all in impact energy dissipation process [3]. 

The activity of the low frequency modes, of acoustic-like nature or mixed acoustical and optical nature, has a more subtle origin, since it is intrinsically related to the presence of electrical and mechanical disorder (Martin, 1974). It is the disordered structure that does not allow a complete destructive interference of the scattered fields, as it occurs in crystals, where the acoustical phonons do not contribute to the Raman scattering (Benassi, 1995). The electrical disorder is caused by the disordered space distribution of the polarizability, as in the case of heavy ions in a silicate glass (Benassi, 1991). Mechanical disorder is the deviation of the vibrational mode patterns from the plane wave shape ofphonons (Martin, 1974). In particular, a depolarized broad peak is present in the Raman spectra of all glasses, the boson peak, at frequencies in the range 20-60 cm . It corresponds to an excess in... 

Another important principle in osteopathic medicine is that stracture and function are intimately interrelated. An abnormality in the stracture of any body part can lead to abnormal function, whether ejq)ressed locally or distantly from the deranged structure. To correct the mechanical disorders, the osteopathic physician undertakes therapeutic osteopathic manipulation. This...
