Taking Jiading district of Shanghai as the study area, which is one of the most typical urbanization fringe regions in Shanghai during the past decades, the urban sprawl in this region from 1989 to 20...
Different alcohols were formylated by formic acid under solvent-free conditions in the presence of iodine as the catalyst with good-to-high yields at room temperature. I2 generated in situ from Fe(NO3...
The stability for a class of linear neutral systems with time-varying delays is studied in this paper, where delay in neutral-type term includes a fast-varying case (i.e., the derivative of delay is m...
The characterization of nanostructured thin films is critical in the design and fabrication of optical sensors. Particularly, this work is a detailed study of the properties of layer-by-layer electros...
Modules or parts of the final product are provided by many suppliers. Some part suppliers design their own products for themselves. In some cases, part supplier may provide the same type product to mu...
The solubilization of cattle achilles tendon with actinidin was investigated under neutral and acidic conditions. 1.43 to 1.92 and 0.97 to 3.19% of collagen were solubilized by treating the cattle ach...
Five strains of fungi belonging to Aspergillus sp. were evaluated by casein agar plate assay and a wheat bran-based solid-state fermentation for selecting a neutral protease-producing culture. Based o...
A number of bi-functional fibre-reactive dye derivatives of C.I. Reactive Red 120 containing quinolino-s-triazine groups were synthesised and their application properties during the dyeing of cotton f...
A neutral exopolysaccharide produced in large amounts by Lactobacillus fermentum TDS030603 was purified from culture supernatants and its structure determined by monosaccharide analysis, methylation a...
Neutral proteinase from Bacillus subtilis was entrapped in dehydrationrehydration liposomes, which were added to pasteurized ewe milk to accelerate Manchego cheese ripening; proteinase level was ,040 ...
A thermolytic lactococcal strain that oversecretes neutral protease was constructed. Plasmid profiles and proteolytic activities confirmed that this strain acquired pMG36enpr containing the cloned neu...
该文引进了一种简洁高效的三电平SVPWM 算法。 在此基础上,提出一种中点电位控制和窄脉冲消除方法,同 时进行了死区的补偿。仿真和实验结果表明,该方法实现简 单,输出波形谐波含量小,中点电位得到很好的控制,并较 好地解决了窄脉冲问题。同时由于进行了死区补偿,使逆变 器在低频输出时波形明显改善,提高了系统在低频时的转矩 输出。在用TMS320LF2407 DSP 为开发平台的三电平实验 ...
Variations in the refractive index of the atmosphere cause variations in satellite-based interferometric synthetic aperture radar (InSAR) observations. We can mitigate tropospheric effects by averagin...
Communication between disciplines in building and construction can be improved significantly by the proper use of Information and Communication Technology. For that reason, many research groups have b...
