Opis:
A new method is introduced to correlate the condensed phase enthalpies of formation of nitroaromatic compounds with their gas phase enthalpies of formation on the basis of the B3LYP/6-31G* and PM3 methods. For the B3LYP method, the condensed phase enthalpy of formation depends on the number of certain elements, nitro groups and aromatic rings. For the PM3 method the number of N=N or N≡N groups, and the presence or absence of three interconnected rings, in addition to some of the parameters mentioned above, are necessary in order to obtain a reliable correlation. For 72 nitroaromatic compounds, the calculated root mean square (rms) deviations of the condensed phase enthalpies of formation of nitroaromatic compounds using the B3LYP and PM3 methods are 63.63 and 32.17 kJ/mol, respectively. The results predicted on the basis of the PM3 method are compared with the best available experimental data.

Opis:
Error is a part of human. Despite that organizations are trying to reduce error to the zero level, this goal is unachievable. As far as human operation is taking place in a complicated environment, error will occurred, and its possibility would be increased under the conditions of stress, extra loading work, and fatigue. One of the most important transportation modes is marine transportations. The sea is an unsafe place that kills many by a simple event. Every year there are thousands of marine accidents that result in injuries, casualties, marine pollutions and also massive financial loss. To reduce the accidents, there should be more attention to the factors such as suitable training of human resource, proper implementation of national and international laws and regulations, vessels and the equipment on board them, port facilities, and also the utilities for marine search and rescue. In this research 1816 marine accidents have been studied in five Iranian shipping companies. 17 factors are known to be effective in occurrence of human error in these accidents. Four factors of the most influence are negligence, poor training, inadequate tools, and lack of skill and experience.
