Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 4,   Pages 448-455 doi: 10.1007/s11709-014-0262-x

Abstract: Rock mass classification system is very suitable for various engineering design and stability analysis. classification method is confirmed by Japan Highway Public Corporation that this method can figure out either strength or deformability of rock mass, further appropriating the amount of rock bolts, thickness of shotcrete, and size of pitch of steel ribs just after the blasting procedure. Based on these advantages of method, in this study, according to data of five deep and long tunnels in Iran, two equations for estimating the value of method from and classification systems were developed. These equations as a new method were able to optimize the support system for and classification systems. From classification and its application in these case studies, it is pointed out that the method for the design of support systems in underground working is more reliable than the and classification systems.

The Potential Role of Powdery Mildew-Resistance Gene <i>Pm40i> in Chinese Wheat-Breeding Programs inthe Post-<i>Pm21i> Era Perspective

Shengwen Tang,Yuting Hu,Shengfu Zhong,Peigao Luo

Engineering 2018, Volume 4, Issue 4,   Pages 500-506 doi: 10.1016/j.eng.2018.06.004

Abstract:

Powdery mildew, which is caused by Blumeria graminis f. sp. tritici (Bgt), is an important leaf disease that affects wheat yield. Powdery mildew-resistance (Pm) gene Pm21 was first transferred into wheat in the 1980s, by translocating the Heuchera villosa chromosome arm 6VS to the wheat chromosome arm 6AL (6VS·6AL). Recently, new Bgt isolates that are virulent to Pm21 have been identified in some wheat fields, indicating that wheat breeders should be aware of the risk of deploying Pm21, although pathological details regarding these virulent isolates still remain to be discovered. Pm40 was identified and mapped on the wheat chromosome arm 7BS from several wheat lines developed from the progenies of a wild cross between wheat and Thinopyrum intermedium. Pm40 offers a broad spectrum of resistance to Bgt, which suggests that it is likely to provide potentially durable resistance. Cytological methods did not detect any large alien chromosomal segment in the wheat lines carrying Pm40. Lines with Pm40 and promising agronomical traits have been released by several wheat-breeding programs in the past several years. Therefore, we believe that Pm40 will play a role in powdery mildew-resistance wheat breeding after Pm21 resistance is overcome by Bgt isolates. In addition, both Pm21 and Pm40 were derived from alien species, suggesting that the resistance genes derived from alien species are potentially more durable or effective than those identified from wheat.

Novel method for the preparation of Cs-containing FAU(Y) catalysts for aniline methylation

Shaposhnik, Marina V. Belova, Boris A. Kolozhvari, Irina I. Ivanova

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 1,   Pages 70-76 doi: 10.1007/s11705-017-1694-3

Abstract: Cs-containing FAU(Y)-type zeolite catalysts were prepared by conventional and novel ion exchange procedures followed by incipient wetness impregnation with CsOH. The novel ion exchange procedure involved hydrothermal treatment of NaY zeolite in aqueous solution of CsCl at 140–200 °C for 6–24 h. The samples were characterized by low-temperature nitrogen adsorption, X-ray fluorescence analysis, X-ray powder diffraction, scanning electron microscopy, Na, Al and Cs magic angle spinning nuclear magnetic resonance, CO and NH -Temperature programmed desorption. The results show that hydrothermal treatment at 200 °C allows to obtain higher degrees of ion-exchange (up to 83%) with respect to conventional method giving maximum 66%–69%. Catalytic properties of Cs-containing FAU(Y) were studied in aniline methylation. The yield of -methylaniline is shown to correlate with catalyst’s basicity. The best catalyst performance was achieved over the catalyst with the highest ion-exchange degree impregnated with CsOH. The selectivity to -methylaniline over this catalyst reached 96.4%.

Neurolemma-Injected <i>Xenopusi> Oocytes: An Innovative <i>Ex Vivoi> Approach to Study the Effects Review

John Clark, Steve Symington

Engineering 2020, Volume 6, Issue 5,   Pages 515-521 doi: 10.1016/j.eng.2019.10.017

Abstract:

Microtransplantation of rat brain neurolemma into the plasma membrane of Xenopus laevis oocytes is an ex vivo method used to study channels and receptors in their native state using standard electrophysiological approaches. In this review, we show that oocytes injected with adult rat brain neurolemma elicited tetrodotoxin-sensitive inward ion currents upon membrane depolarization, which were increased in a concentration-dependent manner by treatment with the pyrethroid insecticides permethrin and deltamethrin. Under our initial protocols, oocyte health was reduced over time and neurolemma incorporation varied between batches of oocytes from different frogs, limiting the usefulness of the assay for regulatory issues. A collection of changes to the assay procedure, data acceptance criteria, and analysis method yield substantially improved precision and, hence, assay performance. These changes established this ex vivo approach as a toxicologically relevant assay to study the toxicodynamic action of pyrethroids on ion channels in their native state using neurolemma fragments prepared from juvenile and adult rat brains.

Presence and Antimicrobial Susceptibility of RE-<i>cmeABCi>-Positive <i>Campylobacteri> Isolated Article

Dejun Liu, Weiwen Liu, Xing Li, Hong Yao, Zhangqi Shen, Yang Wang, Jianzhong Shen

Engineering 2020, Volume 6, Issue 1,   Pages 34-39 doi: 10.1016/j.eng.2019.10.013

Abstract:

Campylobacter spp. (C. spp.) are the leading cause of human gastroenteritis worldwide. RE-CmeABC is a newly identified resistance-enhancing multidrug efflux pump of C. spp. that confers high-level resistance to fluoroquinolones, phenicols, macrolides, and tetracyclines, all of which are critical drugs in both human and veterinary medicine. In this study, we analyzed the presence and antimicrobial susceptibility of RE-cmeABC-positive Campylobacter isolates of food-animal origin from three representative regions (Shandong, Shanghai, and Guangdong) in China over three successive years, from 2014 to 2016. A total of 1088 Campylobacter isolates (931 C. coli and 157 C. jejuni) were recovered from the RE-cmeABC screening. We detected 122 (11.2%) RE-cmeABC-positive isolates of chicken origin, including 111 (70.7%) C. jejuni and 11 (1.2%) C. coli. This multidrug efflux pump is more prevalent among C. jejuni than C. coli. The level of resistance was significantly different in 111 RE-cmeABC-positive C. jejuni versus 46 RE-cmeABC-negative C. jejuni for florfenicol, clindamycin, and erythromycin (P < 0.05), but not for ciprofloxacin (CIP), tetracycline (TET), and gentamicin. However, the isolates harboring RE-cmeABC could shift the minimum inhibitory concentration distribution to the higher range for CIP and TET. Pulsed-field gel electrophoresis (PFGE) analysis suggested that horizontal transmission might be involved in the dissemination of RE-cmeABC in Shanghai and Guangdong, while clonal expansion was predominant in Shandong. Three isolates shared the indiscriminate PFGE types of RE-cmeABC-positive C. jejuni isolates in Shanghai and Guangdong, and four isolates in Shanghai and Shandong. Our study suggests the possibility of a wide dissemination of RE-cmeABC in Campylobacter of food-animal origin, which would pose a significant threat to public health.

Abstract: A convenient and highly efficient method is described for the synthesis of -methoxycarbazole derivatives, including those with sterically demanding, benzannulated, or strongly electron-donating or -withdrawing substituents. Various -methoxycarbazole derivatives were directly prepared in good-to-moderate yields by the Pd (dba) CHCl /9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene-catalyzed reactions of the corresponding dibromobiphenyl compounds and methoxya-mine. Based on this methodology, the first total synthesis of 3,3′-[oxybis(methylene)]bis(9-methoxy-9 -carbazole), an antimicrobial dimeric carbazole alkaloid previously isolated from the stem bark of , was achieved in 18% yield over seven steps from 1,2-dibromobenzene.

Thermal and Mechanical Properties Optimization of <i>ABi>O4 Type EuNbO4 By the<i>Bi>-Site Substitution of Ta Article

Lin Chen, Jing Feng

Engineering 2020, Volume 6, Issue 2,   Pages 177-184 doi: 10.1016/j.eng.2019.12.006

Abstract:

Ferroelastic ABO4 type RETaO4 and RENbO4 ceramics (where RE stands for rare earth) are being investigated as promising thermal barrier coatings (TBCs), and the mechanical properties of RETaO4 have been found to be better than those of RENbO4. In this work, B-site substitution of tantalum (Ta) is used to optimize the thermal and mechanical properties of EuNbO4 fabricated through a solid-state reaction (SSR). The crystal structure is clarified by means of X-ray diffraction (XRD) and Raman spectroscopy; and the surface microstructure is surveyed via scanning electronic microscope (SEM). The Young's modulus and the thermal expansion coefficient (TEC) of EuNbO4 are effectively increased; with respective maximum values of 169 GPa and 11.2×10–6 K–1 (at 1200 °C). The thermal conductivity is reduced to 1.52 W·K−1·m−1 (at 700 °C), and the thermal radiation resistance is improved. The relationship between the phonon thermal diffusivity and temperature was established in order to determine the intrinsic phonon thermal conductivity by eliminating the thermal radiation effects. The results indicate that the thermal and mechanical properties of EuNbO4 can be effectually optimized via the B-site substitution of Ta, and that
this proposed material can be applied as a high-temperature structural ceramic in future.

Frontiers of Agricultural Science and Engineering 2016, Volume 3, Issue 1,   Pages 81-86 doi: 10.15302/J-FASE-2016088

Abstract: As virulence-determining genes, and encode the small subunit and large subunit of viral ribonucleotide reductase (RR) in pseudorabies virus which have been extensively studied in mice. However, their role in pigs has not been adequately investigated. In this study, we deleted and genes based on a / / triple gene-deleted pseudorabies virus and tested its efficacy in pigs as a vaccine candidate. The rescued virus showed similar growth properties and plaque size as its parent strain. In an animal study, the virus could elicit humoral immune responses shown by generation of gB-specific antibodies and virus neutralizing antibodies. However, vaccination could not provide protection against virulent pseudorabies virus challenge since vaccinated pigs showed clinical pseudorabies-specific syndromes. The deficiency in protection may due to the generation of late and low levels of gB antibodies and virus neutralizing antibodies.
