It is necessary to drive forward research on the effectiveness of the biodynamic preparations in order to provide sound practical recommendations for the frequency and timing of their use. However, discussions are required to decide whether it makes sense to assess the effect of individual biodynamic practices in isolation from the overall method, as these practices were proposed as part of a comprehensive farming system (Steiner 2004), the impulse of which is based, in particular, on a holistic understanding of agricultural processes. A complex, holistic, systemic form of science would be appropriate to biodynamic farming (Baars 2002), but has not yet been realised (Lockeretz 2000). It is unclear what would constitute holistic research. Phenomenological descriptions of the overall context are without doubt a key element that has been developed in much detail in the context of anthroposophic research over the past 80 years (Bockemtlhl 1992). However, does holistic research mean that the approach to every... 

The chemical modification of CS biopolymers via reductive amination, to yield alkylated CS derivatives, and further quaternisation result in very efficient antibacterial materials the degree of activity is correlated to the length of the alkyl chain and bacterial strain. The most active CS derivatives are more selective at killing bacteria than the quaternary ammonium disinfectants, cetylpyridinium chloride and benzalkonium chloride, and AMP. Vanillin can be used as a crosslinker of CS nsing this approach, functionalised antimicrobial polymers based on CS, vanillin. Tween 60 and so on may be easily prepared. Imino-CS biopolymer films, prepared by the acid condensation of the amino groups of CS with various aldehydes, can be used as functional biodynamic materials. 

The energy method approach uses Lagrange s equation (and/or Hamilton s principle, if appropriate) and differs from die newtonian approach by the dependence upon scalar quantities and velocities. This approach is particularly useful if the dynamic system has several degrees of freedom and the forces experienced by the system are derived from potential functions. In summary, the energy method approach often simplifies the derivation of the equations of motion for complex multibody systems involving several degrees of freedom as seen in human biodynamics. 

For certain problems where constraint forces are considered, a Newtonian approach, or the aj li-cation of both techniques, may be necessary. The following sections will present some applications of Lagrange s equation as qiplicable to human anatmnical biodynamics. Other mechanically based examples are easily found within the cited literature (Baruh, 19W Moon, 1998 Wells, 1967).
