A new subgenus, Alocanthedon Engel and Gonzalez subgen. n., is described for five species of unusual Southeast Asian bees in the genus Chalicodoma Lepeletier de Saint Fargeau (Megachilinae: Megachilini). The subgenus is most noteworthy for the deep postgenal depression or furrow in males (bordered outwardly near the base of the mandible by a protuberant, thick lamella) and the presence of a den...

in this paper we present some results about subgroup which is generalization of the subgroup $r_{2}^{otimes}(g)={ain g|[a,g]otimes g=1_{otimes},forall gin g}$ of right $2_{otimes}$-engel elements of a given group $g$. if $p$ is an odd prime, then with the help of these results, we obtain the results about tensor squares of p-groups satisfying the law $[x,g,y]otimes g=1_{otimes}$, for all $x, g,...

Recently Havas and Vaughan-Lee proved that 4-Engel groups are locally nilpotent. Their proof relies on the fact that a certain 4-Engel group T is nilpotent and this they prove using a computer and the Knuth-Bendix algorithm. In this paper we give a short hand-proof of the nilpotency of T .

To estimate children's long-term seizure outcomes after hemispheric surgery and the associated predictors.A systematic review of 4 databases and a meta-analysis were performed from January 1, 1995 to August 31, 2015. The databases included PubMed, Embase, Science Direct, and Web of Science; patients were classified into the Engel Class I group and the Engel Class II to IV group, according to th...

Four new species of the subgenus Nanoplebeia Engel (genus Plebeia Schwarz) are described and figured as: (Nanoplebeia) pleres Engel, species, from Venezuela; P. (N.) asthenes Bolivia; orphne Ecuador Peru; chondra Ecuador. A key is presented to subgenus.

An Engel sink of an element g a group G is set $${\cal E}(g)$$ such that for every x ∈ all sufficiently long commutators [⋯[[x, g], g],…, g] belong to . (Thus, precisely when we can choose E}(g) = \{ 1\} $$ .) It proved if profinite admits elementary abelian automorphisms A coprime order q2 prime q each {1} the centralizer CG(a) has countable (or finite) sink, then finite normal subgroup N G/N ...

Classificatory notes are presented for various stem lineages relative to the Trichoptera+ Lepidoptera clade. The following new groups established clades above family-group ranks: Protomeroptera Engel, Metamphiesmenoptera Cladochoroptera Euamphiesmenoptera Eocoronoptera Panendymenoptera Necrotrichoptera Endymenoptera Stelloptera Engel. Additionally, families Marimerobiidae family, and Microptysm...

Euglossella, one of the most distinctive subgenera of orchid bees of the genus Euglossa, is composed of two characteristic assemblages of species, one of them comprising bees bearing the strongly metallic integument trademark of the genus (viridis species group), and the other consisting of bees with a brown integument shaded with metallic iridescence (decorata species group). Here we provide t...

We examined seizure outcome Cfree ,from seizures however minor vs. continuing seizures however infrequent) 5 years post-TLES for mesial temporal sclerosis in 82 consecutive patients, aged 8-43 years, who underwent pharmacologically activated sphenoidal EEG pre-operatively (12 with extracranial ictal monitoring (VT), 70 without). Fifty-six had suffered an early-childhood complicated convulsion (...
