Bis(arylimido) molybdenum(VI) amidinate and guanidinate complexes; Molecular structures of [(ArN)(2)MoMe{N(Cy)C[N(i-Pr)(2)]N(Cy)}] (Ar=2,6-i-Pr2C6H3; Cy = cyclohexyl) and [(2,6-i-Pr2C6H3N)(2)MoCl2]center dot[NH=C(C6H5)CH(SiMe3)(2)]
No full textThe reaction of [(ArN)(2)MoCl2]. DME (Ar = 2,6-i-Pr6C6H3) (1) with lithium amidinates or guanidinates resulted in molybdenum(VI) complexes [(ArN)(2)-MoCl(N(R-1)C(R-2)N(R-1))] (R-1 = Cy (cyclohexyl), R-2 = Me (2); R-1 = Cy, R-2 = N(i-Pr)(2) (3); R-1 = Cy, R-2 = N(SiMe3)(2) (4); R-1 = SiMe3, R-2 = C6H5 (5)) with five coordinated molybdenum atoms. Methylation of these compounds was exemplified by the reactions of 2 and 3 with MeLi affording the corresponding methylates [(ArN)(2)MoMe(N(R-1)C(R-2)N(R-1))] (R-1 = Cy, R-2 = Me (6); R-1 = Cy, R-2 = N(i-Pr)(2) (7)). The analogous reaction of 1 with bulky [N(SiMe3)C(C6H5)-C(SiMe3)(2)]Li . THF did not give the corresponding metathesis product, but a Schiff base adduct [(ArN)(2)MoCl2]. [NH=C(C6H5)CH(SiMe3)(2)] (8) in low yield. The molecular structures of 7 and 8 are established by the X-ray single crystal structural analysis

No full textMulti-source domain adversarial graph convolutional networks for rolling mill health states diagnosis under variable working conditions
No full textAs the rolling mill often encounters variable and complicated working conditions and shock loads, unsupervised domain adaptive (UDA) methods are imperative in its health monitoring. However, efforts of applying UDA methods on the rolling mill are negligible, and many existing approaches have constraints in domain adaptation, domain label, and data construction that prevent meaningful features from being extracted. Hence, a multi-source domain adversarial graph convolutional networks framework (MSDAGCNs) is presented to overcome these challenges and combine three essential elements to achieve cross-domain health states diagnosis under variable working conditions. First, a shared feature extract module is introduced to extract common features. Then, the features are input to a multi-source feature extract module to extract the data construction from the graphs generated by a graph construction module. Meanwhile, a multi-source domain adversarial classifier module is modeled to extract multi-source invariant features and classify them. After that, the local maximum mean discrepancy is employed to align the domain categories. Next, a task classifier module integrates the results of the multi-source classifier for reliable health state diagnosis. Results on the two cases can verify that the proposed MSDAGCNs can not only outperform other state-of-the-art methods, but also extract domain-invariant knowledge. Compared with the best-performing method, the proposed method can boost accuracy by 0.53% and 0.83% in the simplest task of the two case studies, respectively. Furthermore, the arrangement of sensors on the rolling mill is discussed to select the optimal location for collecting vibrations
Loss of susceptibility as a novel breeding strategy for durable and broad-spectrum resistance
Full text linkRecent studies on plant immunity have suggested that a pathogen should suppress induced plant defense in order to infect a plant species, which otherwise would have been a nonhost to the pathogen. For this purpose, pathogens exploit effector molecules to interfere with different layers of plant defense responses. In this review, we summarize the latest findings on plant factors that are activated by pathogen effectors to suppress plant immunity. By looking from a different point of view into host and nonhost resistance, we propose a novel breeding strategy: disabling plant disease susceptibility genes (S-genes) to achieve durable and broad-spectrum resistanc
Thermal and Non-thermal Effects of Microwave on Metal and Metal Oxide - A Critical Review
Full text linkThe influence of tourism on the sustaining of vernacular architechtural tradition embodied in the Bai and Naxi dwellings in Yunnan, China.
No full textYunnan is an economically underdeveloped region in south-western China, in which many ethnic settlements are preserved well. Within the last two decades, many ethnic communities at a grass-roots social level have been conducting a series of tourism-related developments of Bai and Naxi dwellings in Yunnan. They are altering, restoring, rebuilding, refurbishing and renewing ordinary Bai or Naxi dwellings into multi-function dwellings, which are not only the residential homes of families, but are also capable of providing an exotic cultural experience for tourists‘ consumption. Nevertheless, Bai and Naxi dwellings are representations of a living culture, embodying a complex set of vernacular architectural traditions which have been transmitted for many generations. When the Bai and Naxi dwellings are involved in tourism development, the transmission and adaptation of these vernacular architectural traditions are changed, and the manner in which such traditions aresustained in new circumstances becomes an interesting problem. This study explores the influence of tourism development on sustaining the vernacular architectural tradition embodied in Bai and Naxi dwellings in Yunnan, China. The researcher has conducted three rounds of fieldwork, choosing 30 Bai and Naxi dwellings involved in tourism development, from four ethnic minority settlements in Yunnan, for investigation. Observation, interview and questionnaire have been applied to collect data, and template analysis has been used to analyse the data. The results of the analysis show that if tourism development is conducted mainly at a community level, itcan enhance the sustaining of the vernacular architectural tradition embodied in Bai and Naxi dwellings. In summary, the sustaining of vernacular architectural tradition is not simply influenced by the nature of tourism, but is highly dependent on the social level of the developers, the construction pattern they choose, and the socio-cultural interaction they produce
