Flavonoids and anthraquinones from Murraya tetramera C. C. Huang (Rutaceae)
No full textPhytochemical investigation of Murraya tetramera C. C. Huang led to the isolation of ten flavonoids (1-10) and three anthraquinones (11-13). Their structures were determined on the basis of MS, NMR, specific optical rotation, and CD spectroscopic data analysis, and by comparison of the obtained data with those reported in the literature. This is the first report for the occurrence of compounds 2, 4-7, and 11-13 in the Murraya species, and all the compounds were isolated from M. tetramera for the first time with the exception of compound 3. The chemotaxonomic significance of these compounds was also discussed. (C) 2014 Elsevier Ltd. All rights reserved.Biochemistry & Molecular BiologyEcologyEvolutionary BiologySCI(E)[email protected]
Effect of linear feedback control on the optimal transient growth in particle-laden channel flow
No full textThe optimal transient growth process in a particle-laden channel flow is studied under the influence of the linear feedback control. The equilibrium Eulerian approach with the assumption that the particles are small and spherical is adopted. The effect of initial distribution of particles on the optimal transient growth of perturbations is discussed. The LQG control of the particle-laden flow system is considered and compared with the no control cases

Miltochrista dongi Huang & Volynkin 2021, sp. n.
No full textMiltochrista dongi Huang & Volynkin, sp. n. (Figs 4, 11) Type material. Holotype (Figs 4, 11): male, “ 3.V.2018, altitude 2100 m, Mt. Dawei, Pingbian Miao Autonomous County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, P. R. China, leg. Si-yao Huang & Tian-tian Yu” [in Chinese], prep. in glycerol by Huang (Coll. SCAU). Diagnosis. Miltochrista dongi sp. n. differs externally from its closest relative M. xihe sp. n. by its smaller size, the narrower forewing, the blackish abdomen (it is dark brown in M. xihe sp. n.), the crimson forewing ground color (it is pale red in M. xihe sp. n.), the presence of a wide blackish patch in the medial part of the forewing from the base to the subterminal area, and the blackish brown hindwing (it is dark brown in M. xihe sp. n.). The wing pattern of M. dongi sp. n. is also somewhat reminiscent of that of Ovipennis (Coccinigripennis) miloslavae (Černý, 2016) from southern Vietnam, but can be readily distinguished from the latter by its larger blackish patch which extends to the wing base (whereas it is not reaching the wing base in O. (C.) miloslavae) and the findamentally different male genitalia structure. The male genital capsule of M. dongi sp. n. is similar to that of M. xihe sp. n., but differs by the valva narrower medially and basally, the conspicuously narrower distal lobe of valva, and the slightly weaker distal saccular process. The aedeagus of the new species is slightly narrower and less elongated in comparison to the genital capsule of M. xihe sp. n. The vesica of M. dongi sp. n. differs clearly from that of M. xihe sp. n. by its narrower main chamber, the absence of spines on the ventral diverticulum, the smaller distal diverticulum bearing a smaller number of spines, and the markedly larger distal plate. Description. External morphology of adults. Forewing length 10 mm in holotype male. Male antenna ciliate, blackish. Legs blackish brown. Head and thorax crimson. Abdomen dark brown. Forewing blackish brown, edged with crimson, with blackish suffusion on veins in the subterminal and terminal areas; cilia crimson. Hindwing blackish brown including cilia. Male genitalia. Uncus long, thin, laterally flattened, curved subapically and apically pointed. Tuba analis moderately broad; scaphium thin, weakly sclerotized; subscaphium presented as setose field. Tegumen short, moderately broad and weakly sclerotized. Juxta shield-like with very deep lower triangular concavity. Valva elongated, narrow, its costal margin convex medially. Costa strongly broadened distally, lacks a distal process. Distal lobe of valva large, with apical moderately sclerotized triangular process. Sacculus with weakly setose dorsal margin. Distal saccular process narrow but robust, elongate, slightly S-like curved and apically blunt. Aedeagus elongated, straight. Vesica broad, with more or less globular main chamber; its ventral diverticulum small, heavily granulated; medial diverticulum broad, globular, bears a series of various-sized robust spines; distal diverticulum short, granulated, bears a cluster of several various-sized spines. Distal plate of vesica broadly triangular, moderately sclerotized. Female unknown. Distribution. The species is known from its type locality only, Mount Dawei in Yunnan Province of China. Etymology. The species is dedicated to Mr. Zhi-wei Dong (Kunming, China), a good friend of the second author who helped him during his trip to Mount Dawei.Published as part of Volynkin, Anton V. & Huang, Si-Yao, 2021, Three new peculiar species of the genus Miltochrista Hübner, [1819] from China (Lepidoptera, Erebidae, Arctiinae), pp. 569-576 in Zootaxa 4970 (3) on page 571, DOI: 10.11646/zootaxa.4970.3.8, http://zenodo.org/record/476688
Storage performance of Taiwanese sweet potato cultivars
No full textThree sweet potato cultivars (TNG57, TNG66, and TNG73), provided by the Taiwanese Agricultural Research Institute (TARI), were stored at either 15 A degrees C or under ambient conditions (23.8 similar to 28.4 A degrees C and 77.1 similar to 81.0 % of relative humidity). Sweet potato roots were randomly chosen from each replicate and evaluated for measurement of weight loss, sugar content analysis, and sprouting after 0, 14, 24, 48, 56, 70, 84, and 98 days of storage. Fresh sweet potato roots were baked at 200 A degrees C for 60 min then samples were taken for sugar analysis. After 14 days of ambient condition storage, the sprouting percentages for TNG57, TNG66, and TNG73 were 100, 85, and 95 % respectively. When sweet potatoes were stored at 15 A degrees C, the weight loss became less and no sweet potato root sprouted after 14 days of storage. Because manufacturers can store sweet potatoes at 15 A degrees C for almost 2 month without other treatments, the supply capacity shortage in July and September can be reduced. The total sugar content slowly increased along with increasing the storage time. After baking, the total sugar content of sweet potatoes significantly increased due to the formation of maltose. Maltose became the major sugar of baked sweet potatoes. Raw sweet potatoes stored at 15 A degrees C had higher total sugar contents after baking than those stored under ambient conditions. Raw sweet potatoes were recommended to be stored at 15 A degrees C before baking
Motuotrichius yangi Huang & Chen, new species
No full textMotuotrichius yangi Huang & Chen, new species (Figs. 1–22) Type material. Holotype (Figs. 1–3): CHINA: ♂, SE Tibet, Motuo County, Hanmi, ca. 2100m, 29.VII.2011, X.- D. Yang leg. (Entomological Laboratory of Shanghai Normal University, Shanghai, China). Paratypes (2 ♂♂, 5 ♀♀ in total): CHINA: 1 ♀, SE Tibet, Motuo County, Hanmi, 2000m, 9.VIII.2005, Hao Huang leg. (Canadian Museum of Nature, Ottawa, Canada); 1 ♂, 2 ♀♀, same label data as holotype except, 4.VIII.2011 (C.-C. Chen Collection, H. Huang Collection); 1 ♂, 2 ♀♀, SE Tibet, Motuo County, 80k, 12.VIII.2012, X.- D. Yang leg. (H. Huang Collection). Etymology. This new species is named in honor of Mr. Xiao-Dong Yang, our good friend who collected the male specimens of this new species. Holotype description. The generic characters mentioned above will not be repeated herein. Length of pronotum-elytra measured from apex of pronotum to the caudal end of elytra: 10.2 mm. Entire body slender like in Indotrichius Krikken, 2009 species. Head including clypeus, eyes and antennae similarly shaped as in Indotrichius ornatus (Jordan, 1895), but with the following differences: clypeus with lateral margins more parallel, not contracted forwards; dorsal surface of head dark green and unmarked, with clypeus metallic; antenna testaceous, with first antennomere and club somewhat green. Pronotum similarly shaped as in Epitrichius fraterculus, with basolateral corner of pronotum distinctly deflexed; dark green in color and unmarked; heavily punctate everywhere, with white, subappressed setae along lateral margins. Scutellum semicircular and transverse, dark green. Elytra glabrous to the naked eyes and similarly shaped as in Indotrichius ornatus, but a little longer than in the latter; each elytron with 10 complete longitudinal series of irregular punctures, and with additional incomplete series of punctures between first and second striae (counting from suture); interspaces between striae rather flat, sparsely dusted with minute punctures; each elytron with a large anterior orange patch and a small posterior orange patch on the dark green base. Pygidium yellow with midline unmarked, evenly clad with erect, fine setae. Legs slender, with the dorsal surface of protibia dark metallic green, and with all other parts of legs black on dorsal surface, not in great contrast with the body as in Indotrichius ornatus. Ventral surface of the body and the legs black and concolorous. Pilosity of ventral surface of body well developed and pale yellow. Male genitalia (Figs. 15–22): parameres simple, symmetric, depressed, and without branches. Internal sac pigmented and clad with microsetae at middle and apex, without lateral patches formed by larger and darker scales (internal sac of Indotrichius ornatus (Fig. 23) bears three well-separated, large patches formed by markedly larger scales than in Motuotrichius yangi). Description of male paratypes. Individual variation is found in the size of the orange patches on the elytra, which can be smaller than in the holotype or entirely absent (Fig. 4). Description of female paratypes (Figs. 5–6). Sexual dimorphism is only found in the size of the orange patches on the elytra: the anterior patches of female are nearly half as long as elytra, markedly longer than in male. Remarks. The little-known species Trichius dombrowskii Nonfried, 1906 from Manipur, India was described by Arrow (1910) based on a translation of the original description by Nonfried (1906) to have the following characters distinguishable from Motuotrichius yangi: 1) “length 16 mm ”; 2) body “shining coppery red beneath”; 3) pronotum “lightly channelled along the middle”; 4) pronotum “bearing an impression, consisting of closely set punctures, and opaque” near “base of the scutellum”; 5) pronotum green in colour, “the sides having a white margin, with a spot of the same nature almost in the middle”; 6) “elytra dull green, white-spotted”; 7) “pygidium coppery red, closely shagreened, with a large round white spot on each side”; 8) “sides of the abdominal segments white-spotted”; 9) “legs slender, coppery red”; 10) “front tibiae bidentate”. Based on the original description translated by Arrow (1910), Trichius dombrowskii should be placed in the genus Tibiotrichius Miyake, 1994. Field observations. The new species is sympatric with Indognorimus costipennis and Indotrichius gorodinskii in the Motuo area of southeastern Tibet. However, it occurs in higher elevations than Indognorimus costipennis and Indotrichius gorodinskii. The first specimen of Motuotrichius yangi was captured by the first author using a high net from the canopy of a forest at Hanmi, Motuo. The others were observed perching on the leaves of plants.Published as part of Huang, Hao & Chen, Chang-Chin, 2016, Motuotrichius yangi, a new genus and species from southeastern Tibet, China (Coleoptera: Scarabaeidae: Cetoniinae: Trichiini), pp. 365-372 in Zootaxa 4205 (4) on pages 369-372, DOI: 10.11646/zootaxa.4205.4.5, http://zenodo.org/record/19716
