In this study, we investigate the phylogeny and taxonomy of the /Camptori clade sensu Soop et al. (2019a). Based on combined nrDNA ITS phylogenetic, morphological, and ecological analyses, the clade includes six species in Europe, four of which are described here as new to science: Cortinarius malavalii, C. marklundii, C. violaceoserrulatus, and C. viridocaelestinus. We also provide a taxonomic revision of the two known species in the clade, C. camptoros and C. viridocoeruleus. In its current concept, the /Camptori clade is mostly represented in frondose woodlands of southern Europe and none of the species is found in the boreal coniferous zones of Northern Europe. Three species are strictly thermophilous Mediterranean-submediterranean species associated mainly with southern Quercus spp., whereas C. camptoros is found mainly in montane Abies forests, and C. marklundii reaches boreonemoral Tilia-Corylus sites in S Scandinavia and alpine Dryas sites in Spain. An identification key to the species is presented.

Abstract Different dLc coating types are applied at an industrial scale by sulzer Metco thin Film. The coatings are generated with different coating architecture. Deposition methods are: magnetron sputtering, electron beam evaporation and PA‐cVd. Reactive magnetron sputtering is used to deposit metal containing a‐c:h coatings (a‐c:h:Me), e.g. MAXit W‐ch. Pure a‐c:h coatings as functional top coatings are used for cavidur®, MAXit® AhdLc and special versions of dylyn® coatings. In addition to the pure a‐c:h coatings, doped a‐c:h coatings are also used. The dylyn® family of coatings is comprised of at least one layer a‐c:h:si:O. The dylyn® coatings may be doped with metal (a‐c:h:ti:si:O) to adapt selected properties like electrical conductivity.

Abstract Abradable seals have been used in jet engines since the late 1960's. Today abradable seals are seeing applications not only in low pressure and high pressure sections of the compressor but also in the high pressure turbine module of jet engines and are gaining ever more attention in industrial gas turbines. Thermal spraying is a relative simple and cost effective means to apply abradable seals. These work by minimizing gaps between rotating and stationary components by allowing the rotating parts to cut into the stationary ones. The types of coatings employed are zirconia based abradable material systems with polymer and, in some cases, hexagonal boron nitride additions. The coatings are designed to work at service temperatures of up to 1200 °C. The objective of this paper is to review various types of commercial and experimental ceramic abradable systems and to assess their performance profiles. The paper will review yttria stabilized zirconia based systems with modified polymer additions and with variable particle sizes of the ceramic phase. Alternative stabilizers and their influence on key coating properties such as thermal shock resistance and abradability will be studied. The paper will also review the influence of plasma spray parameters on coating properties and study the general influence of coating porosity on coating erosion properties and abradability.

The chlorotica-subgroup (species with unidentate protibiae) of the Anomala cuprascens-group (Coleoptera: Scarabaeidae: Rutelinae: Anomalini) from Sulawesi and the Papuan Region is revised. The cuprascens-group and chlorotica-subgroup are morphologically defined. The chlorotica-subgroup includes 28 species, 18 of which are described as new. The new species are: Anomala madangensis, A. malukana, A. kuekenthali, A. durvillei, A. fergussonensis, A. denticulata, A. irianensis, A. bruggei, A. merkli, A. biakensis, A. butensis, A. ophthalmica, A. sarmiensis, A. toxopei, A. papuensis, A. aruensis, A. sulana, A. tahunensis. The following names are placed in synonymy: A. aeneiventris var. fuscipennis Ohaus, 1915 (= A. aeneiventris Fairmaire, 1883), A. bandarra Ohaus, 1916 (= A. maculicollis Hombron & Jacquinot, 1846), A. resecta Ohaus, 1916 (= A. maculi collis Hombron & Jacquinot, 1846), A. stigmatica Ohaus, 1916 (= A. maculicollis Hombron & Jacquinot, 1846), A. ternatana Lansberge, 1879 (= A. aeruginosa Boisduval, 1835), A. aerea Blanchard, 1851 (= A. aeruginosa Boisduval, 1835). Lectotypes are selected for the nomnal taxa Anomala aeneiventris Fairmaire, 1883, A. pygidialis Kirsch, 1876, A. chlorotica (Guérin-Méneville, 1838), A. maculicollis Hombron & Jacquinot, 1846, A. stigmatica Ohaus, 1916, A. resecta Ohaus, 1916, A. bandarra Ohaus, 1916, A. aerea Blanchard, 1851, A. cassiana Ohaus, 1923. Neotypes are designated for Anomala bousqueti LeGuillou, 1844 and A. aeruginosa Boisd val, 1835. The examination of endophalus structures allows discrimination of species and is indicative of relationships between these species. Descriptions and a key to all taxa treated are included. Figures of the aedeagi and endophalli as well as distribution maps for all taxa are provided.

The cryogenic system of the HERA superconducting proton accelerator has a total cooling capacity of 3 times 6500 Watts at 4.3 K and 3 times 20 KW around 60 K. Its first operation started in 1987 and since the end of 1990 the complete system operated continuously at 4.3 K. We report on the experience gathered during 30000 operating hours of the three cold boxes and the corresponding 14 screw compressors together with the helium distribution system and the purification system.
