Effect of thermally aged oil on space charge dynamics in oil/paper insulation system
No full textThe formation of space charge in oil/paper insulation system can lead to material degradation in the high electrical field region and affect system reliability. Therefore, it is important to understand factors that affect space charge formation in oil/paper insulation system. In the present study the effect of thermally aged oil on space charge dynamics in oil/paper insulation system has been investigated using the pulsed electroacoustic (PEA) technique under different dc electrical fields at room temperature. The condition of oil was characterised. The ultraviolet/visible (UV/Vis) spectrum of oil shifts to visible wavelength and the oil acidity increased as the ageing time increased. It has been found that oil property has a significant effect on the space charge distribution of oil/paper insulation system. The more the deterioration of the oil and the higher the applied voltage, the larger the amount of negative charge injected into the paper near to the cathode and the positive charge accumulated at the paperpaper interface near to the cathode. The maximum electric field strength for oil/paper sample with seriously aged oil under 4kV and 6kV is more than 20% higher than its average electric field strength

No full textTetraploa cylindrica C.F. Liao & Doilom, sp. nov. (FIGURE 3) Index Fungorum number: IF558012; Facesoffungi number: FoF 09425 Etymology:—In reference to cylindrical conidia of the fungus to be same as below line (Holotype) Holotype:— KUN-HKAS 1047393 Saprobic on decaying stems of Saccharum arundinaceum. Sexual morph: undetermined. Asexual morph: hyphomycetous. Colonies effuse, dark brown to black, gregarious on host substrate. Mycelium semi-immersed or immersed, branched, septate. Conidiophores absent. Conidiogenous cells integrated, determinate. Conidia 18–42 × 15–27 µm (x = 30 × 22 µm, n = 40), cylindrical with obtuse ends, dark brown to black, composed of four columns of cells, 4-septate in each column, coarsely verruculose, mostly with three apical appendages, some with one, two or four appendages. Appendages 40–210 µm long, 3–6 µm wide at the base, gradually tapering to the tip, 1–2 µm wide at the apex, divergent, pale brown to brown, 6–13-septate, straight or slightly flexuous, smooth-walled. Culture characteristics:—Conidia germinated on PDA at room temperature (25±2 ˚C) within 12 hours, germination tube grow from both ends. Colonies reaching 13 to 16 mm in diam. after four weeks at 28 ˚C, mostly immersed in culture, irregular, dense, raised in the middle. Front grey brown in the middle, dark brown to black towards the margin, umbonate, flossy, velvety; Reverse black with brown margin. No pigments production. Material examined:— China, Yunnan Province, Kunming city, from decaying stems of Saccharum arundinaceum Retz. (Poaceae), 19 July 2019, C.F. Liao, (KUN-HKAS 1047393, holotype), ex-type living culture KUMCC 20-0205 = ZHKU 22-0054; ex-paratype living culture ZHKUCC 22-0087. Notes:— Tetraploa cylindrica forms a well-supported subclade with T. aquatica, T. dashaoensis and T. nagasakiensis in our multi-locus phylogenetic analysis (FIGURE 2). They share similar morphological characteristics in having cylindrical conidia with four columns of cells and four apical appendages, as well as the overlapping conidial body size. However, T. cylindrica differs from T. aquatica in having divergent and longer appendages (40–210 µm long). In contrast, T. aquatica has closely adhered and shorter appendages (98–134 μm long, Li et al. 2020). Tetraploa dashaoensis has divergent appendages, but they are slightly longer than T. cylindrica (148–258 μm long vs. 40–210 µm long) (pers. comm. Jayawardena R.S.). Tetraploa nagasakiensis has a divergent and similar length of appendages with T. cylindrica, but T. nagasakiensis has brown conidia compared to the dark brown to black conidia of the latter (Tanaka et al. 2009). Tetraploa cylindrica resembles T. aristata in having cylindrical conidia with four columns of cells and four apical appendages, but differs in having longer appendages (40–210 µm long vs. 12–80 µm long) (Ellis 1949). A synoposis of Tetraploa cylindrica and similar species is also provided in TABLE 2. Based on both morphological and multi-locus phylogeny the taxon isolated in this study is established as a new species.Published as part of Liao, Chun-Fang, Dong, Wei, Thilini Chethana, K.

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Model for single-particle dynamics in supercooled water RID F-2194-2011
No full textWe analyze a set of 10 M-step molecular dynamics (MD) data of low-temperature SPC/E model water with a phenomenological analytical model. The motivation is twofold: to extract various k-dependent physical parameters associated with the single-particle or the self-intermediate scattering functions (SISFs) of water at a deeply supercooled temperature and to apply this analytical model to analyse of new high resolution quasielastic neutron scattering data presented elsewhere. The SISF of the center of mass computed from the MD data show clearly time-separated two-step relaxations with a well defined plateau in between. We model the short time relaxation of the test particle as a particle trapped in a harmonical potential well with the vibrational frequency distribution function having a two-peak structure known from previous inelastic neutron scattering experiments. For the long time part of the relaxation, we take the alpha relaxation suggested by mode-coupling theory. The model fits the low-temperature SISK over the entire time range from 1 fs to 10 ns, allowing us to extract peak positions of the vibrational density of states, the structural relaxation rats 1/tau of the cage (the potential well) and the stretch exponent beta. The structural relaxation rate has a power law dependence on the magnitude of the wave vector transfer k and the stretch exponent varies from 0.55 at large k to unity at small k
Cicurina spiralis Liao & Yin & He & Xu 2022, spec. nov.
No full textCicurina spiralis Liao & Xu, spec. nov. (ḄṀ洞叶Ħ) Figures 4–5, 8 Type material. Holotype male (HNU613): China, Guangdong Province, Shaoguan City, Shixing County, Chebaling National Nature Reserve, 24°42.19'N, 114°09.29'E, 532 m, 3 September 2020, Ailan He, Jinxin Liu, Huijuan Sheng, Jia Tang and Yun Liang leg. Etymology. The specific name is derived from the Latin adjective “ spiralis ” and refers to the spiral apical end of the conductor. Diagnosis. The male of this new species is similar to those of Cicurina bifurca spec. nov. and C. calyciforma. The palps of these species share similar embolus and RTA morphology, but can be distinguished by the spermophor clearly visible ventrally through the tegular integument and the simple single spiral of the apical end of the conductor with a very small ventral apophysis in C. spiralis spec. nov. (Figs 4D–F, 5A–C), versus spermophor indistinct and the spiraled apical end of the conductor more complex and strongly bifurcated in C. bifurca spec. nov. (Figs 2D–F, 3A–C). The male of this new species is also similar to that of C. calyciforma. Both species share similar RTA morphology and similar spermophor which can be clearly seen through the tegular integument, but can be distinguished by different apical end of the conductor: as is mentioned above in C. spiralis spec. nov. (Figs 4D–F, 5), versus only weakly bifurcate (nearly “normal”) in C. calyciforma (figs 11C–E in Wang et al. 2019). Description. Male (Holotype): Total length 2.83, carapace 1.35 long, 1.15 wide, opisthosoma 1.27 long, 1.03 wide. Carapace pyriform and pale. AME smaller than other eyes, and the anterior eye row straight and posterior eye row procurved (Fig. 4C). Eye sizes and interdistances: AME 0.02, ALE 0.07, PME 0.06, PLE 0.07; AME–AME 0.01, AME–ALE 0.01, PME–PME 0.04, PME–PLE 0.03, ALE–PLE 0.03. MOA 0.15 long, anterior width 0.07, posterior width 0.18.

Opisthosoma oval, slightly dark gray, and without any distinct patterns. Palp (Figs 4D–F, 5A–C). Retrolateral tibial apophysis (RTA) well developed, distally extended to nearly half of cymbium length, and with a typical Cicurina rolled and thickened retrolateral margin. Spur slightly triangular. Cymbium slightly short and relatively stout (length to width ratio less than 2:1). Embolus (E) originating at approximately 7 o’clock position, and with the first 1/4 wide and the apical 3/4 filamentous. In ventral view of tegulum, spermophor clearly visible.
