Here we describe the flat wasp genus Glutodon gen. nov., and its single species G. mikeaensis sp. nov. from Madagascar. The males of this genus are easily recognized among the other genera of Pristocerinae by having the metasoma with a conical flap expansion on the sternum VIII and the hypopygium with the anterolateral apodeme very thick along its length with a very gibbous tip, both conditions unique in Bethylidae. Glutodon gen. nov. is the sixth genus of flat wasps endemic of Madagascar, and the 30th of Pristocerinae.

Abstract We present a uniform analysis of transit observations from the Hubble Space Telescope and Spitzer Space Telescope of two warm gas giants orbiting K-type stars—WASP-29b and WASP-80b. The transmission spectra, which span 0.4–5.0 μm, are interpreted using a suite of chemical equilibrium PLATON atmospheric retrievals. Both planets show evidence of significant aerosol opacity along the day–night terminator. The spectrum of WASP-29b is flat throughout the visible and near-infrared, suggesting the presence of condensate clouds extending to low pressures. The lack of spectral features hinders

Aims. We set out to study the atmosphere of WASP-80b, a warm inflated gas giant with an equilibrium temperature of ~800 K, using ground-based transmission spectroscopy covering the spectral range from 520 to 910 nm. The observations allow us to probe the existence and abundance of K and Na in WASP-80b’s atmosphere, existence of high-altitude clouds, and Rayleigh-scattering in the blue end of the spectrum. Methods. We observed two spectroscopic time series of WASP-80b transits with the OSIRIS spectrograph installed in the Gran Telescopio Canarias (GTC), and use the observations to estimate the

AbstractThe flat wasp genus Sierola Cameron, 1881 is reviewed from Norfolk and Phillip Islands for the first time. Six new species are described: S. bounites sp. nov., S. dysmica sp. nov., S. idae sp. nov., S. incomitata sp. nov., S. longisetae sp. nov., and S. phillipensis sp. nov. The fauna is surprisingly large for such small islands, but consistent with high diversity of the genus found elsewhere in the Pacific. The low collecting effort and small number of specimens for most of the species suggests that more remain to be found.

I support this line of reasoning by firstly giving definitions of the terms ‘genre’ and ‘parody’ and by then introducing a background to the subject of genre in relation to the novel.

Pattern speed is an important parameter of the density wave theory for spiral galaxies.

We have also extracted the transverse velocity field for the warped galaxy using the same data.

While the flat fragment of assumption-based argumentation (ABA) is widely studied in the literature, the general, non-flat case has mostly been neglected so far. Until recently, there was no possible way to instantiate non-flat ABA in terms of an abstract argumentation framework. While this gap has been closed for complete-based ABA semantics, capturing admissible-based semantics cannot yet be achieved by looking at the relation between the instantiated arguments only; it requires augmenting arguments with their premises, hence being a semi-abstract instantiaiton.

The original criterion for assessing the remaining strength of corroded pipe was an outgrowth of extensive work on the effects of longitudinal cracks in pressurized pipes. This work was carried out in the 1960s under sponsorship of PRCI, and it led to the development of the NG-18 surface flaw equation. Subsequently, an effort was begun under the sponsorship of Texas Eastern Transmission Corporation which continued under PRCI sponsorship which involved adapting the surface flaw equation to predicting the remaining strength of corroded pipe. The result of this work was the ASME B31G methodology

This report is on a jointly funded project by DOE and PRCI. The DOE version of this report was separately published in 2008. This project dealt with various aspects of prediction of the stress-based and strain-based girthweld flaw tolerance of linepipe steels, as well as some supplementary investigations.

X-ray Computed Tomography (XRCT) was initially developed and utilized in the medical industry to image the internal structure of the human body. X-ray imaging was conceived and realized at the turn of the 20th century and subsequently, XRCT, was conceived in the middle of the 20th century and its development continues today. Near the end of the 20th century industrial cone beam XRCT for applications such as dimensional metrology branched off, including its use for identifying and dimensioning flaws. XRCT has been utilized successfully for three-dimensional imaging of flaws in the small panel c

Failures due to stress-corrosion cracking (SCC) generally involve several adjacent, parallel, deep cracks that because of their proximity coalesce to form long flaws, which can cause ruptures.Recent studies indicate that such multiple flaws cause a local increase in compliance as compared to a single crack that represents the largest of the cracks involved.This means that the failure pressure for such a group of cracks can be poorly represented by a single flaw failure criterion, such as the Pipe Axial Flaw Failure Criterion (PAFFC) developed for the Pipeline Research Council International, In
