Topotypes 11♂ 25♀ (NHMSU), CHINA: Guizhou, Suiyang, Wenquan Town, Guihua Village, Hejiao Cave, 28°15´N, 107°17´E, altitude 695 m, 17 April 2015, Y. Lin and H. Yang leg. Diagnosis. With the exception of S. wulongensis, male of S. bifurcata can be distinguished from all other congeners by the embolus with an asymmetrically furcate end (Fig. 6f vs. Fig. 6a–d, 6g –h), and female of S. bifurcata differs by the stubby, sclerotized central process (Fig. 8A vs. Figs. 5C–D, 7A–C, 9A–B). S. bifurcata similar to S. wulongensis in the shape of palpal bulb and the configuration of vulva, but male of S. bifurcata can be distinguished from that of S. wulongensis by the starting position of embolus (Fig. 6F vs. Fig. 6E, the position indicated by the blue arrow) and the unequal length of branches of embolic tip (Fig. 6f vs. Fig. 6e); female of S. bifurcata separated by the smaller, “Ω”-shaped inner vulval plate, and the shorter central process (Fig. 8A vs. Fig. 8B).

No full textRoscoea cangshanensis M. H. Luo, X. F. Gao & H. H. Lin, a new species of the Zingiberaceae from Yunnan, China, is described and illustrated. The new species is related to R. forrestii Cowley in habit, but differs in having 2-lobed labellum, each lobe 2-lobulate, base narrowed to a stalk with white lines, and narrower leaf blade, (2-)7-24X1.5-2.5 cm, with base narrow to petiole-like. The new species is also similar to R. debilis Gagnep. in having leaf base narrow to petiole-like, labellum obovate-cuneate, 2.5-3.5X2.5-3.0 cm, with white lines at throat, but differs in having bracts non-tubular, shorter, 5-15 mm long, concealed in leaf sheaths, corolla tubes longer, 10-12.5 cm long, labellum. 2-lobed with each lobe further 2-lobulate

Diagnosis. Male of S. wulongensis differs from males of all other congeners with the exception of S. bifurcata by the furcate embolus (Fig. 6E–e vs. Fig. 6A–D, 6a–d, 6G–H, 6g –h); it differs from male of S. bifurcata by the narrower, longer oval bulb, the embolus with two equilong tip branches, and the embolus starts from the submesialback surface of bulb, but the embolus of S. bifurcata with asymmetric branches that origins from prolateral surface of bulb (Fig. 6E–e vs. Fig. 6F–f). Female of S. wulongensis seems also close to S. bifurcata having a similar vulval structure, but it can be distinguished by the lager “ω”-shaped inner vulval plate, and the longer, weakly sclerotized central process (Fig. 7F vs. Fig. 7D).

Review of Mayer, R.; Knothe, F.; Shuo, H. (2022) Reflected beauty: Chinese reverse glass paintings from the Mei Lin Collection
No full textIn this well-documented, bilingual, and richly illustrated catalogue, published for the long-anticipated exhibition Reflected Beauty: Chinese Reverse Glass Paintings from the Mei Lin Collection at the University Museum and Art Gallery of the University of Hong Kong (September 2021-January 2022), the authors give us a profound insight into the phenomenon of reverse painting on glass and mirror paintings, with a particular focus on those from the Mei Lin Collection assembled by the Sinologist, author, and translator Rupprecht Mayer and his wife Haitang Mayer-Liem. Composed of over one hundred works acquired in East Asia between 1968 and 2012, this is one of the world's most important collections of Chinese reverse glass paintings from the late nineteenth and twentieth centuries.Modern and Contemporary Studie

Holotype ♂, paratypes 1♂ and 1♀ (IZCAS), CHINA: Guangxi, Pingxiang, Xiashi Town, Xinming Village, Banxiaotun, Banxiao Cave, 22°5.542'N, 106°52.148'E, altitude 175 m, 26 July 2011, X. Wang leg. Diagnosis. Male of this species is similar to S. halongense (Fig. 6A) and S. lenachanae (Fig. 6D), but can be distinguished from the latter two by the narrower, pointed embolic tip (Fig. 6b vs. Fig. 6a, 6d), and by the vestigial white eyespots lacking black ocular base in the both sexes (see Lin & Li, 2014: fig. 4G–H vs. Lin et al., 2017: figs 16E–F, 21A). Female is close to S. takensis sp. n. in having a similar configuration of vulva, but differs from the latter by the inverted triangular inner vulval plate, the wider, shorter central process (Fig. 7C vs. Fig. 5C–D).

The development of iron-free partially stabilized cement for use as dental root-end filling material
No full textNdong F, Sadhasivam S, Lin F-H, Savitha S, Wen-Hsi W, Lin C-P. The development of iron-free partially stabilized cement for use as dental root-end filling material. International Endodontic Journal, 45, 557564, 2012. Abstract Aim To determine the effect of increasing the proportion of zinc on partially stabilized cement (PSC) produced using a one-step sol gel process. Methodology A one-step sol-gel process of Portland cement-based PSC with Zn was synthesized by replacing iron nitrate. The crystalline phases of the PSC-Zn powder were analysed by using X-ray diffraction (XRD). The experimental groups [i.e. MTA, PSC-Fe (control), PSC with 1% Zn, PSC with 3% Zn, and PSC with 5% Zn] were immersed in simulated body fluid for 3 h, 1 and 3 days to evaluate the hydration product formation. The microstructure and surface morphology were analysed using scanning electron microscopy (SEM). Initial and final setting times of the materials were determined using an ASTM Vicat needle testing machine. To evaluate the cytotoxicity of PSC-Zn system, primary osteoblasts cell lines were used. Results The addition of increased weight percentages of Zn, resulted in a more unstable phase which favoured the formation of a monoclinic structure of C3S with an increased hydration reaction of PSC and reduced setting time. The cytotoxicity testing of PSC with Zn revealed that the material was not toxic. Conclusions The newly synthesized PSC-Zn material had short setting time and was biocompatible
