Pre-main sequence stars in the Orion-Monoceros Complex are either distributed in groups closed associated with dense cores, or dispersed along molecular filaments. Some molecular clouds are apparently affected by the OrionEridanus Superbubble created by the Wolf-Rayet winds and supernovae from the OriOB1 association, whose shock fronts compressed and triggered starbirth in adjacent molecular cl...

abstract this study, aimed to achieve carapace length frequency, depth distribution, determining biomass and length-weight relationship of metapenaeus affinis in shrimp fishing grounds of hormomzgan province. sampling was carried out by trawl net and swept area method from january 2010 to february 2011. samples were transferred to the laboratory and biometric information entered on special form...

this study aimed to investigate the spawning season, length at first maturity (lm 50 ) and sex ratio of metapenaeus affinis in the shrimp fishing grounds of hormozgan province, west of the persian gulf, iran. samples were taken by the swept area method and trawl net with 2 cm mesh size in the cod end from january 2010 to february 2011. results showed that the sex ratio deviated from 1:1 and fem...

Rhinoceros beetles of the species Oryctes boas and O. monoceros were used in this investigation. Both species are large, weighing about 3*5 g and having a wing span of about 10 cm. There appears to be no difference in the flight motors of the two species. The beetles are common in sugar-cane fields and in well-established compost and manure heaps in Natal. The animals were kept in compost in me...
