A study of crude oil‐degrading bacteria from mangrove forests in the Persian Gulf

In a survey on the edaphic mesostigmatic mites in mangrove forests of Qeshm Island, eastern of the Persian Gulf, two species of the family Ascidae were collected in broken cockleshells and sand in littoral zone: Leioseius sepidehae sp. nov. and Protogamasellus mica (Athias-Henriot, 1961). This is the first record of the genus Leioseius from Iran. Leioseius sepidehae sp. nov. is described from adult females. Intraspecific variations of some characters of P. mica are discussed, and based on those, P. primitivus machadoi Genis, Loots & Ryke, 1967 and P. primitivus similis Genis, Loots & Ryke, 1967 are herein synonymized under P. mica. Finally, the occasional presence of the gland pores gv1 in Ascidae is reviewed, and a key to the Iranian genera and species of Ascidae is presented.

A New Species

A new species of the laelapid mite genus Gaeolaelaps Evans & Till, G. tuberculatus sp. nov., is described from female specimens collected in soil and rotten leaves under citrus trees in Mazandaran province, northern Iran. Supplementary information on G. deinos (Zeman) is presented. Gaeolaelaps schusteri (Hirschmann) is redescribed based on the type specimens as well as additional specimens collected from the littoral zone of mangrove forests in Qeshm Island, in the eastern part of the Persian Gulf, southern Iran.

Improve Supply Chain

Three refineries of the Indian Oil Corporation procure crude oil from suppliers, at production sites in the Persian Gulf, West Africa, North Africa, West Asia, and India. The crude oil is shipped to two ports in the state of Gujarat, India, by large tankers and medium sized vessels. From these two ports, the crude oil is pumped to the refineries via pipelines. The refineries have known capacity, that are different for the two types of crude oil. In this paper, the scaled-up problem has been modelled, as a transshipment network. Next, the concrete instance of the problem, has been solved using an LP solver. This was followed by post-optimality analysis of the solution. The flow values on all arcs, and optimal product mix, validate actual decisions. Precise shipping requirements obtained from the solution, are shared in advance with marine transporters to improve supply chain coordination.
