In the linear induction motor control system, optical grating speed transducer is susceptible to strong magnetic field interference. What's more, it may reduce integration and raise device costs. Therefore a identification method replace studied in this article. This for mainly adopts Model Reference Adaptive Method (Abbreviated as MRAS) Popov Hyperstability Theory. The research content of paper can be divided into four parts. First, mathematical model based on reference adaptive system...
Ten secondary metabolites (1–10) including a new 4-hydroxycinnamic acid derivatives, methyl 2-{(E)-2-[4-(formyloxy)phenyl]ethenyl}-4-methyl-3-oxopentanoate (1), and nine known compounds (2–10) were isolated from an EtOAc extract derived solid rice medium of endophytic fungal strain Pyronema sp. (A2-1 & D1-2). Their structures elucidated NMR HRMS data. All the tested for antibacterial activity against Mycobacterium marinum ATCCBAA-535. Compounds 1, 8 9 exhibited moderate antibiotic with IC50...
Paraconfuranones A–H were obtained from fermentation extract of fungus Paraconiothyrium brasiliense inhabiting the Acrida cinerea. Their structures elucidated on basis 1D and 2D NMR spectroscopy.

Seeking a strategy for triggering the cryptic natural product biosynthesis to yield novel compounds in plant-associated fungus Xylaria sp., effect of culture conditions on metabolite production was investigated. A shift five known cytochalasin-type analogues 1–5 six new α-pyrone derivatives, xylapyrones A–F (compounds 6–11), from solid liquid medium observed. These were identified by analysis 1D and 2D NMR HRMS data. Compounds 1–3 showed moderate cytotoxicity against HepG2 Caski cancer cell...
Five new 2(5H)-furanone-type derivatives, pestalafuranones F-J (compounds 3-7), together with two known compounds, A (1) and B (2), were isolated from the ethyl acetate extract fermentation broth of endophytic fungus Nigrospora sp. BM-2 in a hypersaline medium. The structures these metabolites elucidated by EIMS, HREIMS NMR spectroscopic data. Compounds 1-7 exhibited no cytotoxic activities against MDA-MB-231 Caski cancer cell lines.
Hydrogenobyrinic acid, a modified tetrapyrrole composed of eight five-carbon compounds, is key intermediate and central framework vitamin B12. Synthesis hydrogenobyrinic acid requires S-adenosyl-methionine working as the methyl group donor catalyzed by 12 enzymes including six methyltransferases, causing great shortage accumulation S-adenosyl-homocysteine, which uneconomic unsustainable for cascade reaction. Here, we report cell-free synthetic system producing integrating using...
A novel metabolite containing sulfur, fusaodavinvin (1), was isolated from an endophytic fungus Fusarium sp.(CTGU-ZL-34), together with seven known compounds 2-8, and their structures were elucidated by NMR spectroscopy MS. This is the first record of 3-(2R-hydroxyl-1-one-propane)-indole (compound 2) nature. The evaluated using A549, Hep G2, Caski MCF-7 cell lines MTT method, compound 1 displayed significant inhibiting activity four cancer IC50 values 11.5, 15.3, 15.2 60.5 microg/mL,...
With the continuous development of electronic equipment, state-based maintenance has attracted more and attention in industry. As an important part maintenance, fault prediction is especially concerned. Because its good generalization ability anti-interference ability, SVR algorithm widely used field prediction. However, still disadvantage that smooth parameter C kernel σ <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> model are...
Abstract Lemongrass oil contains many useful aromatic compounds, some of which have strong deodorizing and antibacterial properties (citral geraniol). The ingredient with the highest content in citronella is Citral (accounting for more than 80% content), plays a key role functionalities disinfectants, biocides, odorants insecticides. This study aims to incorporate lemongrass essential into wax product extend application oil. effect factors that affects process creating was investigated....
With the large-scale grid connection of new energy power, random fluctuation existing in power system is intensified, which leads to frequent load instructions thermal units. It great significance improve variable performance coal-fired more difficult control superheated steam temperature (SST). In order SST, a state fuzzy predictive method proposed this paper. Firstly, Takagi-Sugeno observer used approximate non-linear plant SST. At same time, based on observer, feedback controller designed...
This study proposed the fluidization-like dielectric barrier discharge (DBD) plasma for remediation of lindane contaminated soil and integrated physical chemical reaction pathway. Soil particles distribution within reactor was simulated with Euler-Euler Gidaspow drag models, a bipolar pulsed power supply applied to energize DBD after full fluidized. The effect movement on electric features were discussed in terms voltage waveforms Lissajous figures. Lindane degradation found be related...
Radiation interference on electronic devices is not negligible, and it very important to analyze the causes of impact has. This letter investigates effect X-rays output frequency metal cavity filters. can generate primary secondary electrons in filter cavity. These together form a plasma that affects transmission characteristics electromagnetic wave, thus interferes with operation filter. To investigate this phenomenon, first geometric modeling 3-D filled constructed; then converted into...
The health condition of industrial equipment is closely related to productivity and safety, attaching great importance fault diagnosis. Although current diagnosis methods have already achieved good effect some degree, it more reliable outstanding utilize multiple signal sources pay attention the effective information differences between various signals. In order take full advantage information, this paper proposes a new method based on multi-source signals mechanism. This learns weights...
