Thermo-hydro-chemical couplings considered in safety assessment of shallow tunnels subjected to fire load
No full textFire loading of concrete tunnel linings is characterized by various physical, chemical, and mechanical processes, resulting in spalling of near-surface concrete layers and degradation of strength and stiffness of the remaining tunnel lining. In this paper, the governing transport processes taking place in concrete at elevated temperatures are considered within a recently published fire-safety assessment tool [Savov K, Lackner R, Mang HA. Stability assessment of shallow tunnels subjected to fire load. Fire Safety J 2005; 40: 745-763] for underground structures. In contrast to consideration of heat transport only [Savov et al.], a coupled thermo-hydro-chemical analysis, simulating the heat and mass transport in concrete under fire loading, is performed, giving access to more realistic temperature distributions as well as gas-pressure distributions within the tunnel lining. These data serve as input for the structural safety assessment tool considering, in addition to the temperature dependence of mechanical properties, the effect of the gas pressure on the strength properties of the heated lining concrete. The combination of the two analysis tools (coupled analysis of governing transport processes and structural safety assessment) is illustrated by the fire-safety assessment of a cross-section of the Lainzer tunnel (Austria) characterized by low overburden (shallow tunnel)

Body (Fig. 40) oblong, oval, rather convex, cuticle dark-brown to black with faint to pronounced greenish hue; legs and antennal funicle light reddish-brown; antennal scape somewhat darker. Head: mandibles densely punctate dorsally; clypeus densely and coarsely punctate, almost rugose-lacunose, anterior margin slightly elevated; frontal disc with similar, if somewhat weaker punctation; occasionally this punctation is confluent and forms tiny rugae; frontal stria slightly outwardly arcuate, complete to reduced to interrupted medially, supraorbital stria well developed; eyes flattened, but visible from above. Basal third of frontal disc with irregular rounded glabrous area; occipital stria weak, but visible. Antennal scape somewhat darker than reddish antennal funicle, antennae similar to other species of the subgenus, sensory structures of the antennal club studied by DE MARZO & VIENNA (1982). Pronotum convex, lateral sides slightly narrowing anteriorly; anterior pronotal angles obtuse, marginal pronotal stria complete, its lateral portion observable in some cases from lateral view only. Entire pronotal disc covered with punctures separated by one to several times their diameter, punctation weakens medially. Scutellum very small, triangular. Elytra: elytral epipleuron impunctate, marginal epipleural stria complete, marginal elytral stria well developed, complete, continued as apical elytral stria for short distance. Humeral elytral stria well developed, present on basal elytral third; internal subhumeral stria present as a median fragment. Dorsal elytral striae 1–4 well developed, first the longest, slightly bisinuate, reaching approximately two-thirds of elytral length apically, occasionally even slightly longer, striae 2–4 shorter, reaching approximately elytral mid-length apically, while second stria may be longer than striae 3–4; fourth stria usually the shortest, formed in most cases of beads of punctures, stopping short of elytral mid-length apically. Fourth dorsal elytral stria usually not connected (connected in specimens that belong to form ‘ cribellaticollis ’) with the basal end of (in)complete sutural elytral stria, which is in punctures and can be basally shortened. Elytral punctation covers approximately apical half of elytral disc, slightly surpassing elytral mid-length basally, slightly and scatteredly entering elytral intervals in some specimens; punctation rather dense, punctures separated by approximately their own diameter. Basal elytral fifth, fourth elytral interval, elytral flanks and extreme elytral apex impunctate, or with scattered microscopic punctation only. Propygidium and pygidium: propygidium covered with punctation similar to that of elytra; pygidium with much finer and sparser punctation. Prosternum: prosternal process slightly to moderately concave (observed from lateral view); carinal prosternal striae carinate, divergent on prosternal apophysis, running convergent to sub-parallel to almost approximate apically; from mid-length of prosternal process slightly divergent anteriorly, apically united under tiny loop; interspaces between carinal prosternal striae with scattered punctures. Lateral prosternal stria strongly carinate, convergent apically, united in front of united carinal prosternal striae; lateral sides of prosternal process densely punctate; prosternal foveae moderately large, deep. Mesoventrite: disc of mesoventrite approximately three times as wide as long, with scattered punctures (occasionally almost glabrous); marginal mesoventral stria complete, slightly inwardly arcuate medially; meso-metaventral stria undulate, bisinuate, in punctures, slightly distanced from meso-metaventral suture medially. Metaventrite: disc of metaventrite apart from several rows of tiny punctures situated along basal margin entirely glabrous; lateral metaventral stria almost straight, slightly bisinuate, deeply impressed, in punctures, stopping short of metacoxa; lateral disc of metaventrite depressed, with large oval deep punctures separated by less than their diameter; metepisternum with similar punctation, punctures of smaller sizes than those of lateral disc of metaventrite. First visible abdominal ventrite striate laterally, with scattered fine punctation, occasionally almost impunctate. Legs: protibia (Fig. 32) on outer margin with 8–11 short to moderately long denticles diminishing in size proximally, protibial groove deep; rest of leg characters similar to preceding species. Male genitalia: sternite VIII (Figs 46–47) narrowing apically; sternite VIII and tergite VIII fused laterally (Fig. 48). Tergite IX medio-laterally with tiny acute projection (Figs 49–50). Spiculum gastrale (Figs 51–52) similar to other congeners. Aedeagus (Figs 53–54) almost subparallel, bluntly pointed apically. Distribution. Hungary (?), France, Italy: Sardinia, Sicily, Spain, Portugal, Greece, Malta, Cyprus, Turkey, Tunisia, Algeria, Libya, Egypt. Biology. According to VIENNA (1980), who repeats THÉROND (1975), H. (N.) curtus is found under detritus in sand near the seacoast, where it was collected from near Suaeda sp. and Statice virgata W. plant roots. Remarks. The type specimen was part of Rosenhauer’s collection, which later became partly a part of R. Oberthür’s collection (A. Taghavian, pers. comm. 2017), currently housed in MNHN. The senior author has visited MNHN multiple times and failed to locate the type specimen(s) of this species in the collections of MNHN (including R. Oberthür’s collection). Mr. Serge Risser (Pleucadeuc, France) recently purchased the Histeridae collection of the late Marcel René Paul de Vauloger de Beaupré and published its contents in two separate papers (RISSER 2013a,b). When reading RISSER’ S paper (2013a) we were intrigued by a specimen identified as Hypocacculus (Nannolepidius !) curtus originating from Hungary and from ‘Musaeo Rosenhauer’. Mr. Risser was kind enough to send this specimen to one of us (T. L.). Having examined it as well as compared it to Rosenhauer’s original description we concluded that this is the long-lost type specimen of Rosenhauer’s species Saprinus curtus. This species was described based on an unspecified number of specimens and therefore we designate a lectotype to fix the species identity. Saprinus curtus has become a mystery practically since its description, which was, however, rather detailed and served the purpose well. The reason for this was probably the fact that the type specimen(s) were unavailable for comparison and perhaps also because no more specimens matching this species were ever reported from ‘Hungary’. Based on the description alone, BICKHARDT (1916) correctly synonymized the H. (N.) puncticollis (Küster, 1849) with H. (N.) curtus, which was also followed by REICHARDT (1932). MÜLLER (1937), however, doubted the two species are synonymous since the apical elytral stria in H. (N.) curtus reaches only mid-length of elytral apex, while, according to MÜLLER (1937) it is complete in H. (N.) puncticollis. Furthermore, MÜLLER (1937) advocated using Küster’s H. (N.) puncticollis as the valid (albeit not the earliest) name for this species and suggested, perhaps because of the incomplete description or the absence of the type material, that H. (N.) curtus was a dubious taxon. In the latest treatise on the Histeridae of the USSR (KRYZHANOVSKIJ & REICHARDT 1976), which in fact included almost the entire Palaearctic fauna, Kryzhanovskij upheld MÜLLER’ S (1937) opinion, and the name Hypocaccus (Nessus) puncticollis gained priority. This was followed by MAZUR (1984, 1997, 2011) in all three editions of his world catalogue of the Histeridae as well as by the latest edition of the Palaearctic Catalogue by LACKNER et al. (2015). Having examined both type specimens as well as numerous non-type specimens we can conclude that the two species are synonymous, and the earlier described taxon (H. (N.) curtus) has the priority. Regarding external morphological variation of this species, see Remarks section of H. (N.) curtus . Saprinus puncticollis was described from a specimen found in Cagliari by Küster himself, as well as from specimen(s) brought by Mr. Handschuh from Cartagena (Spain) (KÜSTER 1849). The depository of the Spanish specimens is unknown and hence we designate the male specimen from Cagliari (Sardinia) as the lectotype to fix the identity of this taxon for purpose of synonymy. Saprinus cribellaticollis was described based on unknown number of specimens.A single specimen was located in the original collection of Jacquelin du Val, deposited in MNHN, under the label ‘ Saprinus cribellaticollis ’. Jacquelin du Val did not provide his specimens with any labels, but, according to the curator of Coleoptera in MNHN, A. Taghavian, he kept his types in his private collection. Therefore we presume that this specimen, which completely matches J. du Val’s description, is a syntype. The species was described based on an unknown number of specimens and therefore we designate the lectotype to fix the taxon identity for purpose of synonymy. Saprinus sicanus was described from Sicily (Italy) based on an unspecified number of specimens, therefore we designate the lectotype to fix the taxon identity for purpose of synonymy. Saprinus revisus was described from Algiers (Algeria) based on an unknown number of specimens, therefore we designate the lectotype to fix the taxon identity for purpose of synonymy. The type of S. curtus was found in mid-19 th century ‘Hungary’. This vague locality could refer to anywhere in the former Hungarian monarchy, which stretched south to the Adriatic Sea. It is possible that this species will be discovered in countries of the former Yugoslavia. It is a rather rare and seldom-collected species apparently spread around the Mediterranean Sea. Its rarity and slight morphological differences regarding dorsal punctation or course of carinal prosternal striae probably account for its numerous synonymies. Hypocaccus (Nessus) controversus (G.

Diagnostic description. This species is externally rather similar to the preceding species and therefore here we provide only the diagnostic description outlining the differences between the two taxa. Body (Fig. 45) somewhat more round and more flattened, light to dark brown, with light bronze hue (never with greenish hue). PEL: 2.00–2.30 mm; APW: 1.00–1.10 mm; PPW: 1.50–1.70 mm; EW: 1.65–1.90 mm; EL: 1.25–1.50 mm. Frontal disc more finely punctate than the one of H. (N.) curtus; pronotum medially almost impunctate. The first dorsal elytral stria is only slightly longer than the second (apically both striae 1–2 surpass slightly elytral half), never reaching ¾ of the elytral length apically (in H. curtus the first dorsal elytral stria is substantially longer, occasionally surpassing ¾ of elytral length apically). Sutural elytral stria always connected basally with fourth dorsal elytral stria (in H. curtus these two striae are joined only in specimens that belong to the ‘ cribellaticollis ’ form), can occasionally be shortened apically. Carinal prosternal striae strongly convergent apically, their apices very approximate, stopping posterad of united lateral prosternal striae; their united apices not forming a ‘loop’ as in H. curtus. MÜLLER (1937) mentioned another character: the mesoventral punctation is supposed to be denser and coarser in ‘ controversus ’ than in ‘ puncticollis ’ (= H. curtus). According to our observations, this is a valid, but not entirely stable character, since even among the few ‘ controversus ’ specimens we were able to examine we saw a specimen with only weak mesoventral punctation; the majority of specimens had their mesoventrite densely punctate. Male genitalia (Figs 55–63) are generally similar to the preceding species, the aedeagi differ most markedly: the one of H. (N.) curtus is sub-parallel and blunted apically, while the one of H. (N.) controversus is shorter, stouter, slightly dilated in apical third with acutely pointed apex (compare Figs 53 and 62). Note.

All paratypes provided with following red and printed label: ‘ Hypocaccus (Nessus) / hungaricus sp.nov. / PARATYPE 2017 / Det. T. Lackner & G. Seres’ Differential description. The new species (Fig. 14) is generally very similar to H. (N.) rufipes, differing from it only slightly. Therefore we chose not to provide the new species with a full description, rather pointing out the most significant characters that differentiate it from H. (N.) rufipes . Body (Fig. 14) generally smaller (PEL: 1.40–2.00 mm; APW: 0.75–1.00 mm; PPW: 1.25–1.50 mm; EW: 1.45–1.80 mm; EL: 1.00–1.30 mm), more rectangular-oval (H. (N.) rufipes is more round-oval); pronotum more parallel-sided, anterior angles distinctly obtuse; punctation of pronotal disc laterally very coarse and dense, punctures sometimes almost forming elongate rugae (in H. (N.) rufipes punctation of pronotal disc likewise becomes denser laterally, but punctures never form elongate rugae); cuticle never metallic, rather dark-brown to almost black (in H. (N.) rufipes cuticle is variable, but often shiny to slightly metallic, can be with bronze or even greenish hue); alutaceous microsculpture among frontal punctures more marked than in H. (N.) rufipes. Males with two faint, but discernible small tubercles situated on basal third of metaventrite medially (Fig. 15). The two species differ in the form of male terminalia, especially eighth sternite, which is narrowing anteriorly in H. (N.) hungaricus while it is almost parallel-sided in H. (N.) rufipes (compare Figs 16–17 with 3–4). The aedeagus of H. (N.) hungaricus is slightly shorter and stouter than in H. (N.) rufipes (compare Figs 10 with 23). Etymology. Patronymic, named after the country of origin. Distribution. Known so far only from Hungary and Austria. Records from Austria do not carry any specified data and could also originate from the former Austro-Hungarian Empire meaning that they were actually collected in Hungary. An overlooked species, confused with H. (N.) rufipes, possibly spread over a larger area. Biology. So far found only in the burrows of European Ground Squirrel (Spermophilus citellus (Linnaeus, 1766)); an apparent nidicole. A single specimen was collected in a nest of Formica sp., probably accidentally. Some specimens were collected in pitfall traps baited with cottage cheese. Note. Already REICHARDT (1941: 296) mentioned ‘some specimens from Hungary possess more parallel-sided pronotum with distinctly obtuse anterior pronotal angles, while their body measurements are generally smaller’. Unfortunately REICHARDT (1941) did not pay much attention to these character states and did not compare the male genitalia among populations. Obviously he also overlooked the faint metaventral tubercles.Published as part of Lackner, Tomáš & Seres, Gábor, 2018, Revision of the subgenus Nessus of the genus Hypocaccus from Central Europe, with description of a new species (Coleoptera: Histeridae), pp. 419-439 in Acta Entomologica Musei Nationalis Pragae (Acta.

PARATYPE: YEMEN: SOCOTRA: J, side-mounted on a triangular mounting point, genitalia extracted, dismembered and glued to the same mounting card as the specimen, with labels identical to those of the allotype (TLCM). Description. Body (Figs 14–15). PEL = 2.60–2.80 mm; APW = 0.80–0.90 mm; PPW = 1.30–1.50 mm; EW = 1.40–1.60 mm; EL = 1.60–1.80 mm, flattened, elongate, color light castaneous-brown. Head. Eyes strongly flattened, not visible from above. Frontoclypeal area finely punctate, slightly depressed, traces of supraorbital striae visible above eye, other striae absent. Labrum flattened, rectangular, each mandible with large triangular subapical tooth. Maxillary palpi very prominent, terminal maxillary palpomere longer than mandible itself, visible from dorsal view. Mentum large, quadrate, labial palpi thick, terminal labial palpomere rather thick, its width approximately half its length. Submentum considerably smaller than mentum, triangular. Antennal scape massive, its length approximately equals to that of antennal funicle. Pedicel thickened, approximately as long as antennomeres III and IV together; club large, oval, setose, intersegmental sutures visible. Pronotum almost quadrate, along midline slightly broader than long, anterior angles strongly projected, acute. Marginal pronotal stria very thin, present only on apical angles and behind head; lateral pronotal stria slightly distanced from pronotal margin, parallel to it, terminating anteriorly on anterior pronotal margin. Pronotal disc impunctate; pronotal hypomeron asetose. Elytra impunctate, approximately twice as long as broad, lateral epipleura bistriate, striae thin, complete; subhumeral elytral striae absent, humeral elytral stria very thin, bifurcate. Elytral disc only with scattered microscopic punctation, dorsal elytral striae 1–4 complete, stria 5 almost complete, shortened basally. Sutural elytral stria absent. Propygidium broad, approximately 2.5 times as broad as long, with scattered deep ocellate punctures, separated by approximately 1.5–2.0 times their diameter. Pygidium in basolateral angles with two shallow depressions, each with deep fossa; pygidial surface basally with several vague shallow punctures, otherwise impunctate. Prosternal lobe (Fig. 15) large, rounded, with scattered microscopic punctation; marginal prosternal stria present, weakened to absent on apex. Carinal prosternal striae present as very vague rudiments on prosternal apophysis; lateral prosternal striae double, deeply impressed, subparallel and bisinuate; surface of composite ventral plate laterad to it with large deep ocellate punctures. Mesoventrite (Fig. 15) anteromedially deeply inwardly arcuate, marginal mesoventral stria present, thin, disc glabrous. Metaventrite (Fig. 15) flattened, with scattered microscopic punctation, lateral metaventral stria long, almost straight, nearly reaching metacoxa. Lateral disc of metaventrite with several large deep ocellate punctures; metanepisternum covered by elytral epileuron, not visible. Abdominal ventrite I (Fig. 15) with scattered microscopic punctation, striate laterally. Legs. Protibial spur prominent; protarsal groove deep; outer protibial margin with 5 rather prominent teeth topped by tiny denticle; teeth 2–3 widely separated; mesotibia on outer margin with two widely spaced short denticles, two additional longer denticles situated near tarsal insertion; outer margin ventrally with sparse row of tiny widely spaced denticles. Metatibia slightly longer than mesotibia, otherwise similar to it, except for there is only a single denticle on outer margin medially instead of two. Male genitalia. Sternite VIII (Figs 16–17) divided into two parts; tergite VIII and sternite VIII not fused (Fig. 18). Tergite IX (Fig. 19) divided into two parts; tergite X (Figs 19–20) small, its basal part wedged between the divided parts of tergite IX; sternite IX (Figs 19–20) or spiculum gastrale apically divided into two ‘tails’, pointed basally. Aedeagus (Fig. 21) tube-like, median lobe protruding from tegmen; phallobase (Fig. 22) approximately 1.5 times shorter than fused parameres. Differential diagnosis. The Socotran species strongly resembles the species Liopygus decemstriatus (Motschulsky, 1863) from Sri Lanka. It can, however, be readily distinguished from it based on the following characters: both dorsal elytral striae 2 and 4 are complete in the Socotran species (incomplete in L. decemstriatus); dorsal elytral stria 5 reaches even further basally in the Socotran species; propygidium of the Socotran species is entirely punctate (only partly punctate in L. decemstriatus); pygidium of the Socotran species is punctate only in its proximal part between the two fossa (pygidium of L. decemstriatus is punctate entirely). Comments. The genus Liopygus Lewis, 1891 contains 16 described species distributed exclusively in southeast Asia (MAZUR 2011).All Liopygus species, as far as known, live under bark, preying on small arthropods (DESBORDES 1919). Although DESBORDES (1919) published a key to the species of the genus, difficulties using it for species determination were voiced by GOMY (2006), who described the only species of Liopygus after the World War II. The discovery of a member of Liopygus in Socotra Archipelago, considerably far from the distribution area of the genus is highly interesting, and we advocate a revision of the genus. Etymology. Specific epithet, the Latin adjective ‘ occidentalis ’ (= western), refers to the disjunct geographical location of the new species. Distribution. Endemic to Socotra Island, so far known only from the highest part of Hagher mountains.Published as part of Lackner, Tomáš & Vienna, Pierpaolo, 2017, Histeridae of Socotra (Coleoptera: Histeroidea), pp. 55-76 in Acta Entomologica Musei Nationalis Pragae (Acta.

SIGN CHANGES IN THE ELECTRIC DIPOLE MOMENT OF EXCITED STATES IN RUBIDIUM-ALKALINE EARTH DIATOMIC MOLECULES
No full textIn a recent series of combined experimental and theoretical studies we investigated the ground state and several excited states of the Rb-alkaline earth molecules RbSrfootnote{F. Lackner, G. Krois, T. Buchsteiner, J. V. Pototschnig, and W. E. Ernst, Phys. Rev. Lett., 2014, 113, 153001; G. Krois, F. Lackner, J. V. Pototschnig, T. Buchsteiner, and W. E. Ernst, Phys. Chem. Chem.

Mol. Spectrosc., in Press (2015), doi:10.1016/j.jms.2015.01.006} The group of alkali-alkaline earth (AK-AKE) molecules has drawn attention for applications in ultracold molecular physics and the measurement of fundamental constantsfootnote{M. Kajita, G. Gopakumar, M. Abe, and M. Hada, J. Mol. Spectrosc., 2014, 300, 99-107} due to their large permanent electric and magnetic dipole moments in the ground state. These properties should allow for an easy manipulation of the molecules and simulations of spin models in optical lattices.footnote{A. Micheli, G. K. Brennen, and P. Zoller, Nature Physics, 2006, 2, 341-347}
In our studies we found that the permanent electric dipole moment points in different directions for certain electronically excited states, and changes the sign in some cases as a function of bond length. We summarize our results, give possible causes for the measured trends in terms of molecular orbital theory and extrapolate the tendencies to other combinations of AK and AKE - elements.Made available in DSpace on 2016-01-05T20:03:32Z (GMT).
