Individuals from ten various nations attended the convention which was once in lots of methods a sequel to a symposium held on the collage of Georgia in April 1983. The relevant target of this convention used to be to supply a discussion board for chemists and mathematicians to have interaction and turn into higher expert on present actions and new advancements within the large parts of chemical topology and chemical graph conception.

Example text

Croom divides these research types roughly into positivist and constructivist types. The positivist types emphasize observable facts derived from validated reliable measurements and provide results and conclusions which can be verified and generalized. The constructivist types depend upon the researcher as a participant, holding the view that actions and phenomena are present due to specific circumstances present at that moment. This research attempts to identify clear, observable facts which are precursors of accidents.

Because case histories are used, certain steps of the protocol will be superfluous and unfortunately it will be not possible to perform some steps. Never-the-less, some valuable insights can still be retrieved from the case histories. In Chapter 7 the derived structured protocol will be applied to multiple case studies in the Dutch chemical process industry. Three case studies will be conducted to derive the answers on the posed research questions and to confirm or reject the results from the case histories in the previous Chapter.

Examples of deviations with ’high’ consequences that are ‘directly’ related to safety are: damage to or the malfunctioning of high-risk equipment, leakage of hazardous substance, or injury to people, etc. Examples of ‘low’ consequence deviations (‘indirect’ safety related consequences) are: the malfunctioning of, or damage to non-critical equipment, problems with operational performance such as product quality problems or backlog of maintenance, etc. The 158 deviations found are positioned in the risk matrix shown in Figure 14, where the grey area represents the risk coverage area.
