The pagurid hermit crab genus Trichopagurus de Saint Laurent, 1968 is currently represented by three shallow water spe- cies from the tropical Indo-West Pacific region. In this paper, three species of the genus, including one new species, are reported. Trichopagurus tenuidactylus n. sp. is described on the basis of a single ovigerous female from the Bohol Sea, the Philippines, and compared with...

For small colleges, the use of invertebrates in undergraduate learning laboratory experiments may be a valuable alternative to the use of vertebrate species. This article describes a habituation experiment using terrestrial hermit crabs. All of the materials required are inexpensive and readily available. What makes this experiment unique is that although the instructor sets basic parameters, s...

A new species of the hermit crab genus Diogenes Dana, 1851 (Diogenidae), D. canaliculatus, is described and illustrated on the basis of material from off the Kerala State, southern India. It is referred to the D. edwardsii (De Haan, 1849) species group, and compared with D. bicristimanus Alcock, 1905, D. fasciatus Rahayu & Forest, 1995, D. laevicarpus Rahayu, 1996 and D. moosai Rahayu & Forest,...

This paper evaluates the performances of the OWL 2 reasoners HermiT, FaCT++ and TReasoner in the context of an ontological decision support system in designing entity-relationship diagrams during software development. First, I described a developed ontology which is the knowledge base of the developed application for designing databases. In the first set of experiments I compared how the classi...

The entire mitochondrial gene order of the crustacean Pagurus longicarpus was determined by sequencing all but approximately 300 bp of the mitochondrial genome. We report the first major gene rearrangements found in the clade including Crustacea and Insecta. At least eight mitochondrial gene rearrangements have dramatically altered the gene order of the hermit crab P. longicarpus relative to th...

Distribution of temperature during the welding process is essential for predicting and realizing some important features such as microstructure welds, heat-affected zone (HAZ), residual stresses, their effects. In this paper, a numerical model was developed using COMSOL Multiphysics dissimilar laser (butt joint) AISI 316L Ti6Al4V thin sheet 2.5 mm thickness. A continuous mode (CW) fiber heat so...
