Catastrophic release of diesel and fuel oil from their storage tanks can lead disasters to human, property and the environment. Thus consequences analysis of the accident has significant importance to human communities living in the surrounding area and the authorities involved in land planning. Consequence analysis is normally carried out using mathematical models for predicting the impacts of chemical accidents. This paper presents result of the consequence analysis from study cases namely catastrophic release of diesel and fuel oil from their storage tanks using Simulation of Chemical Industrial Accident (SCIA) software. The software is a user-friendly and effective tool for evaluating the consequences of major chemical accidents, process decision making for land-use planning, namely locating suitable hazardous installations, hazardous waste disposal areas and emergency response plan. Release of diesel and fuel oil might escalate to pool fires and thus require evaluating their characteristics and the posed hazard. It is recommended for future land planning and development, a town must be located at least half kilometre away from the storage tanks to minimize the disaster impacts.

Anthocyanins extracted from flowers of Delonix regia and Hibiscus sabdariffa were coupled with diazotised aniline. Spectroscopic analysis revealed the resulting product to be 4-phenylazo phenol. This study provides a viable use for anthocyanins as an alternative source of phenol used in the synthesis of this dye.

A new sugar-mimic alkaloid, (2R,3R,4R)-2-hydroxymethyl-3,4-dihydroxypyrrolidineN-glyoxylamide (1) and a novel natural sugar-mimic alkaloid, (2R,3R,4R)-2-[(S)-1,2-dihydroxyethyl]piperidine-3,4diol (2), as well as nine known compounds, were isolated and identified from Faeces bombycis. Compounds 1 and 2 showed remarkable inhibitory activity against α-glucosidase with the IC50 value of 1.9 and 6.2 μM, which were 93.4 and 28.6 potent folds than that of acarbose. The results showed that the sugar-mimic alkaloids from Faeces bombycis exhibit significant and reasonably broad range α-glucosidase inhibitory activity, which may be useful in the prevention of the postprandial hyperglycemia and provide new candidates for the treatment of diabetes mellitus.
