The effect of oxygen starvation on ignition phenomena in a reactive solid containing a hot-spot
No full textIn this paper, we explore the effect of oxygen supply on the conditions necessary to sustain a self-propagating front from a spherical source of heat embedded in a much larger volume of solid. The ignition characteristics for a spherical hot-spot are investigated, where the reaction is limited by oxygen, that is, reactant + oxygen ? product. It is found that over a wide range of realistic oxygen supply levels, constant heating of the solid by the hot-spot results in a self-propagating combustion front above a certain critical hot-spot power; this is clearly an important issue for industries in which hazard prevention is important. The ignition event leading to the formation of this combustion wave involves an extremely sensitive balance between the heat generated by the chemical reaction and the depletion of the reactant. As a result, for small hot-spot radii and infinite oxygen supply, not only is there a critical power above which a self-sustained combustion front is initiated there also exists a power beyond which no front is formed, before a second higher critical power is found. The plot of critical power against hot-spot radius thus takes on a Z-shape appearance. The corresponding shape for the oxygen-limited reaction is qualitatively the same when the ratio of solid thermal diffusion to oxygen mass diffusion (N) is small and we establish critical conditions for the initiation of a self-sustained combustion front in that case. As N gets larger, while still below unity, we show that the Z-shape flattens out. At still larger values of N, the supercritical behaviour becomes increasingly difficult to define and is supplanted by burning that depends more uniformly on power. In other words, the transition from slow burning to complete combustion seen at small values of N for some critical power disappears. Even higher values of N lead to less solid burning at fixed values of power

Type species. Fauveliopsis challengeriae McIntosh, 1922, by monotypy. Diagnosis. Fauveliopsids with body medially wider, club-shaped or swollen posteriorly. Segments short, 2–4 times wider than long. Integument opaque, multiannulate or rugose, often with papillae. Interramal papillae prominent, often with a long stalk. In gastropod and scaphopod shells or foraminiferan tests. Remarks. Fauveliopsis McIntosh, 1922 differs from the other genera in the family, Laubieriopsis Petersen, 2000 and Riseriopsis n. gen., because of its body pattern, medially or posteriorly swollen, and by having short medial segments. The body shape is often modified if they were preserved within the mollusk shell or foraminiferan test they occupy. They are more or less tapered if taken from long foraminiferan tests, swollen medially if taken from scaphopod shells, or have a distinct posterior swollen region if taken from gastropod shells. In any case, the integument is opaque and granulose, with intersegmental furrows well-defined, at least along anterior chaetigers.Published as part of Salazar-Vallejo, Sergio I., Zhadan, Anna E. & Rizzo, Alexandra E., 2019, Revision of Fauveliopsidae Hartman, 1971 (Annelida, Sedentaria), pp. 1-67 in Zootaxa 4637 (1) on page 8, DOI: 10.11646/zootaxa.4637.1.1, http://zenodo.org/record/333520

No full textAnti-MAG antibody and antibody complexes: detection by radioimmunoassay
No full textA radioimmunoassay (RIA) for measuring isotype-specific antibodies to the myelin-associated glycoprotein (MAG) was developed using radiolabeled CNS MAG in a double-antibody precipitation system. Anti-MAG activity was detected by RIA only in patients with neuropathy and anti-MAG M proteins. Anti-MAG IgM or IgG antibodies were not detected in serum of patients with Guillain-Barré syndrome, chronic relapsing polyneuritis, or multiple sclerosis (MS). Some patients with anti-MAG IgM M proteins also had complexes of IgG or IgA bound to the M protein. In one patient, anti-CNS MAG activity was detected by RIA, but not by ELISA or immunoblot. Anti-MAG antibody activity in patients with neuropathy seems to be isotypically restricted, and there is no evidence for antibody reactivity to MAG in other demyelinating diseases
Dalhousia McIntosh 1885
No full textDalhousia McIntosh, 1885 reinstated Dalhousia McIntosh, 1885: 186. Type species: Dalhousia atlantica McIntosh, 1885, by monotypy. Diagnosis: Hesioninae with two lateral antennae, and one median antenna on dorsal prostomial surface. Palps biarticulate, palpophores large, massive, palpostyles smaller, blunt. Eyes dark, black, brown or reddish, anterior ones larger than posterior ones, sometimes approaching each other in lateral view. Nuchal organs U-shaped. Peristomial dorsolateral and ventrolateral tubercles low, barely projected. Pharynx with upper jaw double, lower jaw transverse plate. Parapodia sesquiramous along chaetigers 1–3, biramous thereafter. Notochaetae from chaetiger 4, subdistally denticulate, delicate, sometimes abundant, usually very long, reaching neurochaetal tips. Neurochaetae compound falcigers, blades bidentate, guards approaching subdistal tooth. Etymology. McIntosh (1885: 186, footnote 2) indicated that the genus group name was named ‘after the Earl of Dalhousie, K.T.’ It was Fox Maule-Ramsay, 11 th Earl of Dalhousie (22 Apr. 1801 – 6 Jul. 1874), who under Queen Victoria was the Secretary of State for War (1855–1858) (Fryde et al. 1941). ‘K.T.’ stands for Knight of the Order of the Thistle, a Scotish order of chivalry. Gender. Feminine. Indicated by the declination of the nominative, and after the combination with the specific epithet, atlantica, used in its feminine acception to emphasize that the type specimen was found in the Atlantic Ocean. Remarks. von Marenzeller (1904: 308), Chamberlin (1919: 190), Horst (1921: 80), and Pleijel (1998: 110) regarded Dalhousia as a junior synonym of Leocrates. It is herein regarded as distinct on the bases of the above diagnosis. It can be separated from other genera in the tribe by following the key above. Roule (1896b: 454) rejected the independent status of Dalhousia McIntosh, 1885 because the morphological characters seemed insufficient, especially regarding the presence of the so-called frontal tubercle. However, McIntosh (1885: 187) included in the diagnosis the lack of median antenna. Further, Roule (1896: 454) regarded Dalhousia as a junior synonym of Fallacia de Quatrefages, 1866 probably because McIntosh (1885: 188) wrongly indicated that the pharynx was unarmed, but Fallacia is a junior synonym of Hesione Savigny in Lamarck, 1818, as indicated elsewhere (Salazar-Vallejo 2018). Roule (1906: 51) modified his perspective by clarifying that Dalhousia was proposed because it lacks median antenna, and pharyngeal jaws, and he regarded it as a junior synonym of Tyrrhena Claparède, 1868 based upon a damaged specimen and concluded that ‘Ce genre, avec son unique espèce, doit probablement disparaitre de la nomenclature.’ [This genus, with its only species, should probably disappear from nomenclature]. This conclusion was probably taken too literally, including by McIntosh himself, because he referred to Roule as the author for the species in his subsequent publications (McIntosh 1901: 227, 1908: 130). However, provided that both names refer to the same biological species, Dalhousia atlantica McIntosh, 1885 has priority over Tyrrhena atlantica Roule 1896. On the other hand, there are some differences worth mentioning based on the original descriptions. For example, McIntosh (1885:187) indicated that eyes were reddish-brown, whereas Roule (1906: 54) reported them as purple and, in the same publication, he included a figure to show some features. This difference, however, might depend on the time spent in the ethanol before the study of specimens by these authors. Then, these differences were the high variation of the relative size of eyes (Roule 1906, Pl. 5, Fig. 37), their fusion, pigmentation of nuchal organs, and insertion of the median antenna: between anterior eyes in two cases, central in one (two if figure 36 is included), and between posterior eyes in the other. Regretfully, despite McIntosh (1885: 187) indicated the eyes were placed in a pigmented prostomial area, this pigmentation was apparently not taken into account by Roule (1906) for clarifying the relative size of eyes. Further, as indicated in the above key to Hesioninae genera, Dalhousia McIntosh, 1885 is very similar to Paradalhousia n. gen. by having palps biarticulate, jaws in the pharynx, their nuchal organs as two U-shaped lobes, and parapodia are sesquiramous anteriorly and biramous posteriorly. They differ in some features of the pharynx armature and in neurochaetal pigmentation. In Dalhousia the upper jaw is double, T-shaped, and the ventral one is a transverse plate, but there are no marginal denticles, and neurochaetae are often brownish, whereas in Paradalhousia upper and lower jaws are single, fang-shaped, with a marginal circle of denticles, and neurochaetae are pale.Published as part of Salazar-Vallejo, Sergio I., 2020, Revision of Leocrates Kinberg, 1866 and Leocratides Ehlers, 1908 (Annelida, Errantia, Hesionidae), pp. 1-114 in Zootaxa 4739 (1) on pages 20-21, DOI: 10.11646/zootaxa.4739.1.1, http://zenodo.org/record/367254

Holotype of Sthenelais jeffreysi: BMNH 1921.5.1.616, anterior fragment, length 18 mm, width 3 mm for about 39 segments. Remarks The description above is emended for the terminology used in describing the parapodial bracts and stylodes and the details regarding the shape and location of the neurochaetae. The recently collected specimens of E. hibernica from the Geikie Slide (Northwest Scotland) were in rather good condition and proved very helpful in supplementing the diagnostic characters of the species. Chambers(1985) noted that the type material of Eusthenelais hibernica is unidentifiable and,consequently, Read & Fauchald (2020) list Eusthenelais McIntosh, 1876 as a nomen dubium in WoRMS. However, especially the presence of both spinigers and bidentate falcigers as described by McIntosh (1876b) is sufficient to distinguish it from other sigalionid species. The other important generic character, i.e., the presence of dorsal cirri on segment 3, was not mentioned in the original description, but later described by McIntosh (1900) based on the same material (see respective remark related to generic diagnosis above). We examined the syntypes, which are in rather bad condition, but we can confirm the presence of a pair of dorsal cirri on segment 3 in both specimens. In both publications (1876b, 1900) McIntosh described Eusthenelais hibernica and Sthenelais jeffreysi as different species. It is not clear why he did not realise that these are in fact synonymous, as for both species he described the two types of neurochaetae and, although he did not mention the dorsal cirri in the text for S. jeffreysi, he clearly figured them in his monograph of 1900 (pl. 29 fig. 4). Eliason (1962) noted that not only Sthenelais jeffreysi, but also Sthenelais heterochaeta McIntosh, 1897 could be possible synonyms of Eusthenelais hibernica. For S. heterochaeta again the dorsal cirri are not mentioned, but the original description of the elytral and chaetal characters leaves no doubt that this is E. hibernica. We checked the holotype of S. jeffreysi and found it to be unidentifiable; moreover, the type material of S. heterochaeta seems to be lost. But, as explained above, the respective original descriptions are sufficient and we confirm Eliason’s view that both S. jeffreysi and S. heterochaeta are synonyms of E. hibernica. Compared to the other species described herein, Eusthenelais hibernica presents a number of remarkable characters: The presence of a pair of dorsal cirri on segment 3 is the main differentiating character (absent in all other species). The auricles are smaller and much less obvious. The lateral antennae are of similar length to the dorsal tentacular cirri (versus distinctly shorter). The neuropodial posterior bract is large and obvious, similar to the one found in S. limicola (versus smaller and much less obvious in S. boa, or the Fimbriosthenelais species). Distribution and habitat So far only known from the NE Atlantic: recorded from off Norway, along the western coasts of the British Isles and Ireland, down to Southwest Portugal.
