Habitus as in Fig. 2B. Reddish brown, head usually darker, blackish brown; mouthparts fuscous brown; antennae yellowish brown; elytra with small subtriangular yellow maculae near middle; legs reddish brown, except of paler apex of tibiae and tarsi. Pubescence of body pale, evident and recumbent. Head subtriangular, coarsely and sparsely punctate, widest across eyes; eyes prominent, 1.86 times longer than temples; ocelli distinct, distance between ocelli 1.75 times as long as distance between ocellus and posterior margin of eye. Antennae elongate, relative lengths of the antennomeres I–XI: 1.54: 1: 1: 1: 1: 1: 1.15: 1.15: 1.15: 1.15: 1.77. Pronotum subcordate, moderately convex, widest near anterior third; lateral margins arcuate at anterior twothirds and nearly straight at posterior third; punctation and pubescence as that on head; disc with shallow U-shaped depression. Scutellum subtriangular, surface with fine punctation and pubescence. Elytra subtrapezoidal, gradually dilated posteriorly, posterior angles broadly rounded; punctation and pubescence distinctly finer and sparser than those on pronotum. Abdomen broad, widest at segment IV (first visible abdominal segment), then distinctly narrowed posteriorly. Tergites with dense, fine punctation and decumbent pubescence, devoid of microsculpture; middle of the tergites IV and V with one pair of tomentose patches, but patches on tergite V smaller and less transverse. Male. Apical margin of the tergite VIII (Fig. 3G) broadly concave; sternite VIII (Fig. 3H) transverse, apical margin weakly concave; median lobe of the aedeagus (Figs 5 D–F) slightly longer than parameres; parameres somewhat asymmetrical, each slightly narrowed in anterior half, with three long apical setae; internal sac without sclerotized spines and without distinct dark membranous structures. Female. Abdominal sternite VIII without concavity apically. In other morphological characters similar with males. Comparative notes. Lesteva concava is closest to L. cooteri Rougemont in sharing similar body size, and punctation and pubescence of the head and pronotum. These two species can be readily separated by the different coloration of the body, and especially the narrower aedeagus with longer median lobe and narrower and longer parameres in L. concava. For illustrations of L. cooteri see Figs 6A, 8 A–B, 9A–C and Rougemont (2000: figs 1, 13). Distribution and nature history. China: Anhui, Zhejiang (Fig. 24). Some specimens were sifted from leaf litter near a stream in mixed deciduous forests at Mt. Tianzhu, Anhui. Etymology. The new specific epithet refers to the broadly concave apical margin of the male tergite VIII.Published as part of Cheng, Zhi-Fei, Li, Li-Zhen & Peng, Zhong, 2019, New species and new records of Lesteva Latreille, 1797 (Coleoptera Staphylinidae: Omaliinae) from China, pp. 1-39 in Zootaxa 4560 (1) on pages 5-9, DOI: 10.11646/zootaxa.4560.1.1, http://zenodo.org/record/262725

ABSTRACT Putra, Adhitya Yuwana. 2012. Study about Varieties of Ornamental Building in Cheng Hoo Mosque in Pandaan District, Pasuruan, East Java. Essay, Department of Art and Design, State University of Malang. Supervisor (1) Drs. H.Mistaram, M. Pd, Ph. D. Supervisor (2) Drs. Anak Agung Rai Airmbawa, M. Sn. Keywords: decorative, building, mosque. Existency of Cheng Hoo Mosque in Pandaan are inspired by the atititude of Admiral Cheng Hoo who respected the differences of the religions and beliefs. Based on the author’s observations in Masjid Cheng Hoo Pandaan, there are decorative art combinations of Islamic and Chinese. Finally, the author suggest to Moslems in Indonesia to promote peace and tolerance in touch with people of other faiths because it is commanded in the Qur'an. The problems that examined in this essay are: 1. What is the background of the decorative usage in Cheng Hoo Mosque? 2. What are the ornamental motifs in Cheng Hoo Mosque? 3. How about the placement of the decorative motifs? To answer these problems, the author use some approaches, such us: Semiotics approach, which refers to the relationship between sign and referent. Historical approach, is looking for the origin of the decorative usage in Cheng Hoo Mosque in Pandaan. Structuralism approach, is seeing the changes in the mosque parts that are adjusted each other. According to those problems, the author try to find some sources or files in the both written or oral form. The conclusion of this paper is, Cheng Hoo Mosque in Pandaan is a form of building that have Chinese architecture. In the form of the mosque, there are also several other elements between Islam and China. The basic form of Cheng Hoo Mosque in Pandaan is similar with temples that is usually found in domestic China and serve as a place of religious worship for people who are Confucians.

Piezoresistive semi-transparent flexible sensors by bithiophene fulleropyrrolidine thin films
No full textPiezoresistive sensors are considered among the fundamental components of the future wearable electronic devices, given their potential applications in artificial skin, motion capture and personalized medicine.[1-5] Here, we present a cost-effective, viable fabrication approach to realize piezoresistive sensors using a novel polymeric biotiophene fulleropyrrolidine system (bis-C60Bi) synthesized on flexible ITO/PET supports by electrochemical chronoamperometry. By applying an anodic potential (1.5 V) to a solution containing the monomer, it is possible to obtain a homogeneous semi-transparent thin film on the ITO/PET surface (see Figure). AFM,
XPS, UV-vis have been employed to characterize the morphology and chemical composition of the new synthesized polymeric thin films, confirming the chemical structure and showing a nanoscale surface roughness of about 25 nm. The resulting polymer-based device shows good resistance variation on bending in the semi-static regime, outperforming current ITO/PET resistive sensors [6] and well matching commercial devices based on opaque amorphous carbon materials.[7] The durability of the sensor has been validated over almost one hundred cycles. This new class of polymeric piezoresistive sensors may open new applications in the field of kinematic acquisition or of sensor monitoring, with several potential applications as well as in medicine, robotics and physiotherapy.

Description Basidiomata small to medium-sized. Pileus 14–63 mm in diam., hemispheric at first, applanate with a depressed centre to infundibuliform at maturity, margin smooth when young, often fine striate at maturity, cuticle peeling often one-fifth of the pileus radius; purple pinkish (#ff989b), pale brown (#a95b4c) or greyish white (#ececea), margin grey-white (#e9e9e6), grey-purple (#aaaad5). Lamellae white (#fffff) to pale yellow (#ffffcc), adnate, fragile, up to 6 mm wide, approximately 10–12 pieces per cm near the pileus margin, lamellulae absent, usually forked near the stipe. Stipe 72–105 × 12–27 mm, solid, subcylindrical to slightly inflated at the base, sometimes light brown to brownish orange (#ae6020) when bruised. Context unchanging when bruised, odour unpleasant, taste mild. Spore print not observed. Basidiospores (5.5–)5.8–6.3–6.8(–7.3) × (4.7–)4.9–5.2–5.5(–5.6) μm, Q=(1.02–)1.10–1.21–1.32(–1.45), subglobose to ellipsoid, ornamented with small and amyloid warts of height 0.2–0.9 μm; hilar appendix small, amyloid or weakly amyloid. Basidia (31–)35–40–45(–48) × (8.5–)9.4–11–12(–15) μm, 2- and 4-spored, clavate and slightly inflated in the upper half, thin-walled, with guttate or granular contents, sterigmata 4.3–5.8 × 0.9–1.2 μm; basidiola clavate or subcylindrical, 7–11 μm wide. Pleurocystidia dispersed, (48–)58–71–84(–95) × (8.6–)9.7–11–12(–14) μm, clavate, fusiform, subcylindrical sometimes lanceolate, apically always obtuse, few mucronate, sometimes with a 2–7 μm long appendage, thinwalled, contents granulose, heteromorphous-crystalline, pink in sulfovanillin. Cheilocystidia (33–)40– 51–62(–67) × (6.2–)8.1–9.1–10(–11) μm, clavate and subfusiform, apically always obtuse, sometimes with 3–12 μm long appendage; contents granulose, heteromorphous-crystalline, often dispersed in the upper and middle layers. Marginal cells (20–)22–24–26(–29) × (4.9–)5.6–6.7–7.8(–9.4) μm, clavate or subfusiform, sometimes fusiform. Pileipellis orthochromatic in cresyl blue, sharply delimited from the underlying context, 120–180 μm thick, two-layered, strongly gelatinized, suprapellis 50–80 μm thick, composed of ascending to erect hyphal terminations; subpellis 70–100 μm thick, composed of horizontally oriented, interwoven hyphae. Hyphal terminations near the pileus margin intricate and sometimes branched, occasionally flexuous, thin-walled; terminal cells (11–)15–21–27(–31) × (3.0–)3.3–4.1–4.9(–5.9) μm, mostly subcylindrical, occasionally subfusiform or lageniform, apically usually obtuse, sometimes attenuated or constricted, subterminal cells frequently shorter and slightly inflated, ca 4–7 μm wide, rarely branched. Hyphal terminations near the pileus centre similar to those near the pileus margin; terminal cells (12–)18–26–35(–44) × (2.1–)3.5–4.4–5.3(–6.2) μm, subcylindrical, subfusiform or lageniform, apically usually obtuse, sometimes attenuated or constricted, subterminal cells frequently short, 2–6 μm wide, rarely branched. Pileocystidia near the pileus margin (35–)39–50–62(–68) × (5.0–)5.2–5.8–6.4(–7.5) μm, thin-walled, cylindrical, clavate or subfusiform, apically usually obtuse, sometimes with a 2–5 μm long appendage, contents heteromorphous-granulose, black in sulfovanillin. Pileocystidia near the pileus centre (32–)41–50–59(–71) × (4.3–)4.7–5.8–6.9(–8.9) μm, thin-walled, apically usually obtuse, sometimes with 1–4 μm long appendage, contents with granulose or heteromorphous-crystalline, black in sulfovanillin. Cystidioid hyphae dispersed in subpellis and context, with heteromorphous-granulose contents, oleiferous hyphae frequent in subpellis and context.Published as part of Zhou, Hao, Cheng, Gui-Qiang, Huang, Xiao-Bo & Hou, Cheng-Lin, 2023, Two new species of Russula subgenus Heterophyllidia (Russulaceae, Russulales) from Yanshan Mountains, North China, pp. 185-202 in European Journal of Taxonomy 861 on pages 194-195, DOI: 10.5852/ejt.2023.861.2077, http://zenodo.org/record/775669
