In this paper we propose a conditional logic IBC to represent iterated belief revision. We define an iterated belief revision system by strengthening the postulates proposed by Darwiche and Pearl [3]. First, following the line of Darwiche and Pearl, we modify AGM postulates to make belief revision a function of epistemic states rather than of belief sets. Then we propose a set of postulates for...

With only 43 described stygobionts and two isopod species the obligate groundwater fauna of Iran, a vast country with over 10% limestone surface, is inadequately known. Here, we report discovery Asellus ismailsezarii sp. nov. from Zagros mountains, first eyeless depigmented asellid Iran. The new morphologically similar to monticola Birstein, 1932, but it fully depigmented, has slightly curved p...

This epidemiological review was carried out to display the magnitude and the geographic distribution of scorpion envenomation in Iran with focus on the southwestern region of Iran, particularly. The Iranian recognized scorpions belonging to two families, including Buthidae and Scorpionidae. Buthidae family consists of 14 genuses, 26 species, and 18 sub-species, while Scorpionidae family has thr...

in order to investigation of collembola fauna, several soil and leaf litter sampling were carried out during 2011 in kermanshah regions and species were extracted by berlise funnel. in sum, eight species from eight genera from seven families were collected and identified. the species characterized by one star (*) are new for kermanshah fauna. the species characterized by two star (**) are repor...

abstract the laelapidae is a large family with worldwide distribution. many laelapids are ectoparasitic on small mammals or associated with arthropods, although some species are free living and predators especially in soil habitat; also they are common in stored products. during three years (2007-2009) of faunestic survey, samples were collected from different habitats such as soil, plant litte...

A species of sea anemone found in shallow water areas of southern Kaneohe Bay, Oahu, but never before reported from Hawaii, is described. It is identified as Actiniogeton sesere, previously recorded and described from the Torres Straits (Haddon and Shackleton 1893). HAWAII'S COELENTERATE FAUNA is poorly known and is in need of serious study. As I have discussed elsewhere (Dunn 1974), the single...

Background: Geographical distribution of zoonotic cutaneous leishmaniasis (ZCL) has continuously been extended in recent years in Iran. The Beiza District is one of the newly-emerged endemic foci of ZCL in southern Iran. The main aim of the present study was to detect the vector(s) of ZCL in this area. Methods: To detect the fauna and vectors of ZCL in this district, sand flies were cau...

As a result of the entomological surveys in the Near East, seventeen species of biting midges of the genus Dasyhelea Kieffer are reported. Five new species are described and illustrated from adult males: D. (Dicryptoscena) antonii sp. nov., D. (Pseudoculicoides) avia sp. nov., D. (Ps.) libanensis sp. nov., D. (Ps.) nauta sp. nov. and D. (Ps.) sandrageorgei sp. nov. Among the remaining species, ...
