During a 2013 cruise in the Southern Ocean we collected specimens of the octocoral Plumarella delicatissima between 800 and 950 m depth. Five new furanocembranoid diterpenes, keikipukalides A-E (1-5), the known diterpene pukalide aldehyde (6), and the known norditerpenoid ineleganolide (7) were isolated from the coral. These Plumarella terpenes lack mammalian cytotoxicity, while 2-7 display act...

The adults of Calochromini with male flabellate antennae were studied. Two new Calochromus Guérin-Méneville, 1833 species with flabellate antennae, C. kelantanensis spec. nov. and C. harauensis spec. nov. are described. Dumbrellia Lea, 1909 (Calochromini) is proposed as a new junior synonym of Plateros Bourgeois, 1879 (Lycinae: Platerodini). Flabellochromus Pic, 1925 is transferred to Calochrom...

The micromorphology and elemental composition of celestobarite crystals in a duripan from central Australia are examined. These crystals are flabellate (fan-shaped), have a Ba/Sr ratio of 11.1, and are up to 50 p.m in size. The location of the celestobarite crystals within silicified roots and in close association with calcite and clay coatings indicates that these celestobarite crystals are au...

In this research, modelling of the leaves with help divisor functions are worked on. Given a positive integer k (1 ≤ 100), we investigate solutions equation σ(n) = σ(n + 2k) odd square-free n. Further, for l and prime q, there no results σ2i(n) σ2i(q). As an application, pose basic structure model real-time virtual ecosystem construction derived from shifted functions. Also, elliptic, flabellat...

Peer-to-peer (P2P) technology provides a popular way of distributing resources, sharing, and locating in a large-scale distributed environment. However, most of the current existing P2P systems only support queries over a single resource attribute, such as file name. The current multiple resource attribute search methods often encounter high maintenance cost and lack of resilience to the highly...

The Hawaiian antipatharian coral previously identified as Leiopathes glaberrima (Esper, 1792) and Leiopathes sp. is described using polyp morphology, skeletal spine morphology and in situ photographs, and assigned the new name of Leiopathes annosa sp. nov. The species is characterized by tall (1 m or more), fan-shaped colonies, with thick, sometimes overlapping branches, and tissues that are co...
