Six species of Phryno Robineau-Desvoidy and three species of Botria Rondani are revised, including four new species: P. brevicornis sp. nov., P. koreana sp. nov., P. nepalensis sp. nov. and P. tenuiforceps sp. nov. A key to the species of these genera is provided. A phylogenetic analysis was performed using morphological characters to investigate the placement of genera in the Zenillia group (s...

Nine species of Alysson Panzer 1806 are recorded from Russia and adjacent territories. The new synonymy is proposed for Alysson pertheesi Gorski 1852 =A. fuscatus var. jaroslavensis Kokujev 1906, =A. harbinensis Tsuneki 1967; Pompilus spinosus (Panzer 1801) =Alysson katkovi Kokujev 1906. The number of valid species-group taxa in the genus Alysson is reduced to 39 species. An original key to the...

Tachysphex pompiliformis (Panzer, 1804) and Tachysphex austriacus Kohl, 1892 species subgroups belong to the Tachysphex pompiliformis species group, and both subgroups consist of morphologically similar species. The Tachysphex austriacus Kohl species subgroup comprises four species in Europe and Turkey. For this subgroup, differential diagnoses of Tachysphex austriacus and Tachysphex prismaticu...

SYNOPSIS INTRODUCTION Brain-based learning, a recent approach in the educational literature, is related with the structure and the relation of the functioning of the brain with learning. The pioneers of this approach (Caine & Caine, 1994) have come up with principles about brain and learning. Another recent approach, constructivism, is also concerned with teaching and learning and has brought i...

Peer-to-peer based gaming is a new paradigm for distributed multiplayer online gaming that has attracted attention in the last years. It is known that P2P based topologies offer good scaling properties and mitigate unfairness otherwise observed for peers being far away and thus having large network lags. However, removing inconsistencies for high paced action games like FPS or tank battle games...

For the first time, we report for Siberian fauna species ant-loving cricket Myrmecophilus acervorum (Panzer, 1799) (Orthoptera: Myrmecophilidae), found in anthills of Lasius sp. (Hymenoptera: Formicidae), that is most north-eastern locality this rare finding. We suggest an alien nature M. distribution Siberia.
