Figure 2 in Revising the definition of the crustacean seta and setal classification systems based on examinations of the mouthpart setae of seven species of decapods

Figure 2. Types of projections found on the general cuticle. A, type I projection, a seta, is an elongate circular projection, which is articulated with the general cuticle (arrow). It is the most common type of projection. B, type II projection, a seta, from maxilla 1 of Pagurus bernhardus with a more or less direct transition into the general cuticle. In the other species articulated setae are situated in the same place (compare with Fig. 11A). They may have small outgrowths (arrows). C, type III projections, denticles, from maxilliped 1 of Panulirus argus. Arrows indicate direct transition into general cuticle without an articulation. D, type IV projections, setules, from the paragnath of Stenopus hispidus. Arrows indicate serration and arrowheads indicate articulation with the general cuticle. Note the flattened shape at the base.

Development of standardized definitions for Combined and Composite High Voltage Tests

Driven by the increasing demands on traceable measurement systems and calibration services, being able to fully cover the required needs, a large number of NMIs have put a great effort on the development of standardized wave shapes definitions, low voltage calibrators, measuring instruments and software for combined and composite high voltage tests. The European Metrology Programme for Innovation and Research (EMPIR) supports this work through the normative Joint Research Project 19NRM07 HV-com², which started in 2020 and has received funding from the EMPIR co-financed by the Participating States and from the European Union's Horizon 2020 research and innovation program.
