Final Statement

Remarkable ecotoxic effects caused by the biodegradation of polymers have rarely appeared in all reviewed papers and reports. Fortunately, a generally very small hazard potential could be assumed. An extensive investigation, applied before the market introduction of a newly designed or composed material, may act as a safety net to avoid unwanted negative effects on ecosystems. The additional cost of such analysis is very low compared with the value of environmental damage unexpected metabolites may cause and compared with the probable loss of confidence of the material users and waste treatment plant operators. 

The currently available standards provide an analysis scheme and limit values for a general acceptance of biodegradable materials, which are intended for waste utilisation. Additional standards dealing with material applications in the environment will follow soon. All these guidelines should be understood as minimal requirements 

It became a universal principle in the science of applied ecotoxicology to interpret even a small reduction of the growth rate of an organism in a laboratory test as an indicator for the disappearance of a species in a natural ecosystem. Although that statement sounds conservative it should be recognised before the introduction of any artificial substances into nature. 

The current development status of bioassays for compost and soil samples does not allow differentiation between the effects in the range below 10%. More research will be needed to fully discover the complex chemical reactions involved in the biodegradation process of artificial polymers. In the meanwhile, the material producers should pay substantial attention to the environmental behaviour of their products. The goal is to avoid any appearance of negative effects in the environment caused by a practical application on a large scale. 

A broad use of biodegradable materials should preferably replace conventional plastic which is used for products with a short lifetime, such as plastic bags or vegetable packaging. Degradable plastic in litter accumulates and harms the environment, not only in the sea, but in soil as well. This new generation of products could be one of the many pieces of the puzzle enabling harmonisation of a modern life style and the protection of nature - but only if some essential requirements are fulfilled.

The next few sections deal with the way these experimental results can be developed into a mathematical system. A reader prepared to accept the second law on faith, and who is interested primarily in applications, may skip section A2.1.4.2 and section A2.1.4.6 and perhaps even A2.1.4.7. and go to the final statement in section A2.1.4.8. 

A final statement on the mechanism of the diaziridine formation cannot yet be made. The obvious formulation [Eq. (36) ] as a reaction of the CN double bond with the imen 39 (with an electron sextet) is almost certainly excluded. The formation of 39 as an intermediate has been jiroposed for the Raschig hydrazine synthesis, but has been disjmted. The following facts are against a diaziridine formation corresjionding to Eq. (36) ...

From the perspective of the chemist, DQA can be broken down into seven steps shown in Figure 5.3. Similar to the DQO process, the steps may undergo several iterations before the final statement is formulated depending the purpose of data collection, some of these steps may be modified or even omitted. For example, a DQA conducted for hazardous waste disposal data will not be nearly as extensive as the one for a risk assessment project. 

As a final statement, it must be stressed that much remains to be accomplished with phospholes in coordination chemistry. Practically nothing is known on the C-unsubsti-tuted phosphole complexes coordination with metals such as Ti, Zr, V, W, Ta, Os, Ir, Cu, Ag, Au, Zn, Cd, Hg... has not been seriously investigated. Catalytic activity of phosphole complexes has not been systematically studied. Phosphametallocene complexes are unknown except with Fe(CO)4. Undoubtedly, new exciting developments are at hand. 

Although the identification and analysis of such modifying factors go beyond the scope of trace element analysis, the importance of these factors should be recognized. The complexity of the process that leads from the first step of trace element analysis to the final statement of biological implication necessitates the close collaboration between the analytical chemist and the life scientist. The chemist should not be considered the provider of data, nor the biologist the interpreter of results rather, both scientists must be aware of the whole process—its complexity and its diflBculties (25). Only through this collaboration can the enormous amount of trace element analytical data be put in order and be interpreted properly. On this whole process depends the progress of trace element nutrition research and the improvement of the nutritional status of man. 

The log-normal distribution is also rather universal in the present cell, as demonstrated in the distribution of some proteins, measured by the degree of fluorescence [41]. Now, is this universality the final statement for cell statistical mechanics We have to be cautious here, since too universal laws may not be so relevant to biological function. In fact, chemicals that obey the log-normal distribution may have too large fluctuations to control some function. Some other mechanism to suppress the fluctuation may work in a cell. 

The rules gathered here may serve as a final statement or as a starting point. Engineers have their own operating and design rules or shortcuts, and many of these have been recorded somewhere. Much of that literature is sum-... 

One important function of the elaboration knowledge and its related mental model of the situation is to preserve the order expressed in the relationship from its first manifestation to the second. Consider again the age problem introduced above. The two things in this problem are readily identifiable as Mary and her mother. Their associated measurable properties are ages in years. The relationship of interest is that Mary s age is one-third of her mother s age. The importance of the mental model should be evident here. Without an adequate model, the solver might be tempted to apply a formulaic approach that depends on a sequential parsing of the problem, expecting the two statements of the relationship to maintain their order. In fact, as this simple problem illustrates, the order is often disrupted. In this problem, the initial statement is Mary-related to-mother. In the final statement, we... 

Summary A careful consideration of merits and limitations of these two methods leads us to conclude that Inductive Method is the fore-runner of Deductive Method. For effective teaching of chemistry, both inductive and deductive approaches should be used because no one is complete without the other. Induction leaves the learner at a point where he cannot stop and the after work has to be done and completed by deduction. Deduction is a process that is particularly suitable for final statement and induction is most suitable for exploration fields. Induction gives the lead and deduction follows. In chemistry if we want to teach about composition of water then its composition is determined by a endiometer tube (inductive process) and confirmed by the process of electrolysis of water (deductive process). 

So. at present no final statement about the existence of endemic Baltic species can be made since even for Fucus radicans the existence of this species at other cold and low saline sites off the Baltic must first be proven before giving it the status of an endemic species. 

Ultracentrifugal studies as to the homogeneity of this fraction were unsatisfactory because of the limitations of materials. No final statement can, therefore, be made concerning the molar proportions of zinc to protein, pending establishment of the molecular weight. However, the minimum molecular weight based on zinc content would be 21,700. The magnitude of the zinc content is comparable to that encountered in other metallopro-teins (Tables I, II). The isoelectric point was found close to pH 6.5. 

Aversa s defense, at the opposite end of the spectrum from Magirus, shows the tremendous latitude that an Aristotelian viewpoint could assume on the issue of the artificial and the natural. The truly conservative position on this topic was not to be found in Aristotle himself, but in his interpreters Avicenna, Averroes, and Thomas Aquinas.156 Aversa s final statement on the subject reveals his allegiance to the Liber mineralium of Albertus Magnus, surely as much an Aristotelian as Thomas was. The matter of the metals,... 

Apart from those mentioned above, there are other contaminations known for diamond films, too. Oxygen and silicon are frequently observed with the latter being incorporated into the lattice in a substitutional way as well. Oxygen and further impurities like sulfur or metallic defects have not yet been studied in sufficient detail to give a final statement on their arrangement in the lattice and on their influence on the diamond properties. Calculations indicate that boron, nitrogen, phosphorous, and silicon are the only dopants suitable for a stable incorporation into the lattice.

Although Antiochus s final statement reiterates the cliche that tragedy was supposed to have an educational effect on monarchs - in Sidney s words, it maketh kings fear to be tyrants, and tyrants manifest their tyrannical humours (p. 98) - the conclusion of Believe as You List is left deliberately unresolved through the deferral of death.
