After comparing with male Paralectotype of Alloteratura longicercata (Bolívar, 1905, from Simbang, New Guines), selected by Gorochov (1998: 125) from the same locality as Holotype, the median spine of subanal plate of this species is shorter, similar to that of Alloteratura (Alloteratura) longicercata sulawesi Gorochov, 2016. Posterioventral lobule of the 8th abdominal in female (Gorochov, 2016, Fig. 108) is less distinct as in the 2 subspecies. This species is here to be revised as a third subspecies of Alloteratura longicercata (Bolívar, 1905), considering both morphological similarity and geological distribution. These specimens were identified as Alloteratura angulata Jin, 1995.Published as part of Jin, Xingbao, Liu, Xianwei & Wang, Hanqiang, 2020, New taxa of the tribe Meconematini from South-Pacific and Indo-Malayan Regions (Orthoptera, Tettigoniidae, Meconematinae), pp. 1-53 in Zootaxa 4772 (1) on page 9, DOI: 10.11646/zootaxa.4772.1.1, http://zenodo.org/record/381411
The politics of fashion: perceptions of power in female clothing and ornamentation as reflected in the sixteenth-century Chinese novel Jin Ping Mei
No full textThis thesis examines issues of female power and influence in sixteenth-century China focusing on how women and their roles were perceived in the changing social environment of the mid-late Ming dynasty. Using aspects of a New Historicist approach, information from contemporary literary and historical sources are analysed alongside each other. With its emphasis on the lives of women and preoccupation with the description of material objects, the late Ming novel Jin Ping Mei forms an important element in the thesis. China in the sixteenth century saw expanding urbanisation, the emergence of a new wealthy merchant class, increasing visibility of women and a questioning of traditional morality. Fashion consciousness, as one of the most conspicuous aspects of the new material culture, is a possible indicator of these trends. Traditional Western theories contend that fashion began in the particular context of Renaissance Europe. However, this study argues that a similar fashion awareness existed in China too, and was manifested in a competitive striving for social status, in this case specifically among women. In contrast to previous studies which downplayed the impact women had on defining traditional Chinese culture, this thesis demonstrates how women and their sartorial choices began to redefine the boundaries of material culture, influencing literati discourse which, in turn, re- influenced female behaviour

국문요약 69MasterArticular cartilage is a resilient load-bearing tissue that forms the articulating surface of diarthrodial joints and provides low friction, lubrication, and wearless characteristics necessary for repetitive gliding motion. However, because articular cartilage has neither vascular nor lymphatic channel supply and hence difficult access to stem cells, its self-healing potential is restricted. If left untreated, cartilage damage results in osteoarthritis (OA) and its endstage from, can only be managed by joint replacement surgery. We hereby provide means to repair cartilage using extracellular matrix (ECM) membrane on bone marrow stimulation (BMS) techic and development of a novel analytic method for detection of engineered cartilage.
Chapter Ⅰ: BMS has been regarded as a first line procedure for repair of articular cartilage. However, repaired cartilage from BMS is known to be unlike that of hyaline cartilage and its inner endurance is not guaranteed. The reason presumably came from a shortage of cartilage forming cells in blood clots derived by BMS. In order to increase repairable cellularity, the feasibility of autologous bone marrow-derived buffy coat transplantation in repair of large full-thickness cartilage defects was investigated in this study. Rabbits were divided into four groups: the defect remained untreated as a negative control; performance of BMS only (BMS group); BMS followed by supplementation of autologous bone marrow buffy coat (Buffy coat group); transplantation of autologous osteochondral transplantation (AOTS) as a positive control. Repair of cartilage defects in the Buffy coat group in a rabbit model was more effective than BMS alone and similar to AOTS. Gross findings, histological analysis, histological scoring, immunohistochemistry, and chemical assay demonstrated that supplementation of autologous bone marrow buffy coat after BMS arthroplasty effectively repaired cartilage defects in a rabbit model, and was more effective than BMS arthroplasty alone. Supplementation of autologous bone marrow-derived buffy coat in cases of BMS could be a useful clinical protocol for cartilage repair.
Chapter Ⅱ: The recombinant human transforming growth factor beta-3 (rhTGF-β3) is known as a key regulator of chondrogenesis of stem cells and cartilage formation. We have developed a novel drug delivery system that continuously releases rhTGF-β3 using an extracellular matrix (ECM) membrane fabricated from cultured porcine chondrocytes. We hypothesized that rhTGF-β3-loaded ECM membrane could significantly enhance cartilage regeneration, when it was applied on the osteochondral defect of rabbit articular cartilage treated with the bone marrow stimulation (BMS) technique. New Zealand white rabbits of 16 weeks old (an average weight of 3.0-3.5kg, n=78) were subjected to osteochondral defect on right knee joints and divided into four groups: The defect was (1) left untreated as a negative control (Control group), (2) covered with ECM membrane after BMS (Control-m), (3) treated with direct injection of rhTGF-β3, and covered with the ECM membrane after BMS (TGF-i) and (4) covered with rhTGF-β3-loaded ECM membrane after BMS (TGF-m). The results showed that repair of osteochondral defects was more efficient in the TGF-m group than the other groups including that with direct injection of rhTGF-β3 in gross findings, histological analysis, histological scoring and chemical assays for GAGs, collagen and DNA contents. We speculate that the sustained release of rhTGF-β3 using the ECM membrane after BMS could be a useful clinical protocol for cartilage repair.
Chapter Ⅲ: In cartilage tissue engineering, it is very important to evaluate specifically and non-destructively the quality of engineered tissues in terms of matrix content and their three dimensional (3D) distribution. The objective of this study was to evaluate the feasibility of using microfocal computed tomography (µCT) with Hexabrix, a contrast agent, in examining the quality of engineered cartilage. Chondrocytes were isolated from the knee articular cartilage of 2- to 3-week-old rabbits. Cells at passage 2 (5.0 x 105/ml) were loaded dynamically on polyglycolic acid (PGA) scaffolds (2 mm in diameter and 2 mm in thickness), and cultivated in a chondrogenic defined medium for 7, 14, 21and 28 days in vitro. The engineered cartilages were incubated with undiluted Hexabrix 320 for 20 min and analyzed by µCT scanning. The scanning data were visualized by 2D and 3D images and quantified by counting the number of voxels. The results were validated by histological images of engineered cartilages by Safranin-O staining and proteoglycan content by biochemical analysis. The optimal threshold value for quantification was determined by regression analysis with the total contents of sulfated glycosaminoglycans (GAGs) from 14 individual samples. The biological effect of uCT scanning on the engineered cartilage was also examined for cell viability and total contents of sulfated GAGs and DNA. The 2D µCT image of an engineered cartilage was matching well with the histological image of corresponding section by Safranin-O staining. Quantitative data obtained by 3D µCT images of 14 engineered cartilages showed a strong correlation with sulfated GAGs contents obtained by biochemical analysis (R2=0.883, P<0.001). Repeated exposure of engineered cartilages to Hexabrix 320 and µCT scanning did not affect significantly cell viability, total DNA content and total sulfated GAGs content. µCT imaging using Hexabrix 320 provides high spatial resolution and sensitivity to assess sulfated GAGs content and 3D distribution in engineering cartilage. Therefore it could be a valuable tool to evaluate the quality of engineered cartilage and greatly benefit its developmental process

[M(OOCC6H4PO3H)(H2O)] (M(II) = Mn, Co, Ni): layered metal phosphonates showing variable magnetic behavior
No full textThree novel isomorphous transition metal phosphonate compounds with formula [M(OOCC6H4PO3H)(H2O)] [M(II) = Mn(1), Co(2), Ni(3)] were prepared through hydrothermal reaction of 2-carboxyphenylphosphonic acid and metal salts. Within the structure, the {M2O2} dimers made up of edge-sharing{MO6} octahedra are connected by carboxylate and/orphosphonate groups, leading to a 2-D layer. The phenyl groups fill in the inter-layer spaces. Magnetic measurements reveal that dominant antiferromagnetic interactions are observed in compounds 1 and 2, while for compound 3, the dominant ferromagnetic interaction leads to a spontaneous ferromagnetic long range ordering below T-c = 4.0 K
Optimal beaconing control for epidemic routing in delay tolerant networks
No full textOwing to the uncertainty of transmission opportunities between mobile nodes, the routing in delay-tolerant networks (DTNs) exploits the mechanism of opportunistic forwarding. Energy-efficient algorithms and policies for DTN are crucial to maximizing the message delivery probability while reducing the delivery cost. In this contribution, we investigate the problem of energy-efficient optimal beaconing control in a DTN. We model the message dissemination under variable beaconing rate with a continuous-time Markov model. Based on this model, we then formulate the optimization problem of the optimal beaconing control for epidemic routing and obtain the optimal threshold policy from the solution of this optimization problem. Furthermore, through extensive numerical results, we demonstrate that the proposed optimal threshold policy significantly outperforms the static policy with constant beaconing rate in terms of system energy consumption savings
