Currently, Chinese wind farms are generally equipped with 10% rated capacity lithium-ion battery energy storage system, which often fails to smooth out power fluctuation effectively and fulfill the grid connection standard. The hybrid system combining solid oxide electrolysis cell (SOEC) can be adopted suppress fluctuation. Firstly, model of is built transient response characteristics analyzed in Matlab/Simulink environment. Secondly, configuration strategy developed variational mode...

The improper disposal of construction and demolition waste (CDW) exacerbates the consumption raw materials emissions greenhouse gasses. In this study, due to high recycling rate, focusing on meltable CDW, phase CDW is divided into four stages, namely on-site stage, transportation reprocessing reproduction stage. Second, based these a carbon emission accounting model (CEAM) established evaluate benefits during stages. Third, CEAM applied typical old residential area reduction recycling....

Periodontitis is a widespread oral disease that results in the loss of alveolar bone. Low-intensity pulsed ultrasound (LIPUS), which new therapeutic option, promotes bone regeneration periodontal injury models. This study investigated protective effect LIPUS on oxidative stress periodontitis and mechanism underlying this process. Methods: An experimental model was induced by administering ligature. Immunohistochemistry performed to detect expression levels stress, osteogenic,...

Up to now, there has been no report on the taxonomic and functional analysis of microbial community in fermenting puer tea by pyrosequencing. In this study, metagenomic pyrosequencing was first used delineate a relatively comprehensive overview taxonomy while also preliminarily characterising ontologies genes present pile fermentation.A total 251 738 reads (9197 contigs 145 402 singletons) were generated Taxonomic revealed three dominant bacterial phyla, Actinobacteria (30.08%),...

The interactions between trypsin and gallic acid (GA) were investigated by means of fluorescence spectroscopy, UV-vis absorption resonance light scattering (RLS) synchronous enzymatic inhibition assay. It was found that GA can cause the quenching during process formation GA-trypsin complex, resulting in activity (IC50 = 3.9 × 10-6 mol/L). spectroscopic data showed efficiency reach about 80%. binding constants 1.9371 104 L/mol, 1.8192 1.7465 L/mol at three temperatures, respectively....

Pathogenesis-related proteins (PRs) are a class of that accumulate in response to biotic and abiotic stresses protect plants from damage. In this study, gene encoding PR-like protein (PnPR-like) was isolated Panax notoginseng , which is used traditional Chinese herbal medicines. An analysis expression P. indicated PnPR-like responsive an infection by the root rot pathogen Fusarium solani . The induced several signaling molecules, including methyl jasmonate, ethephon, hydrogen peroxide,...

We report the complete sequence of a calcium channel alpha 1 subunit cDNA cloned from Drosophila head library. This encodes deduced protein containing 2516 amino acids with predicted molecular weight 276,493. The shares many features vertebrate homologs, including four repeat structures, each six transmembrane domains, conserved ion selectivity filter region between domains 5 and 6, an EF hand in carboxy tail. has unusually long initial terminal tails. corresponding to last domain (IVS6)...

Recent developments in Fourier transform infrared spectroscopy-partial least squares (FTIR-PLSs) extend the application of this strategy to field edible oils and fats research. In work, FT-IR spectroscopy was used as an effective analytical tool determine peroxide value virgin walnut oil (VWO) samples undergone during heating. The spectra were recorded from a film pure between two disks KBr for each sample at frequency regions 4000–650 cm −1 . Changes values most bands observed build...

A rapid HPLC method had been developed and used for the simultaneous determination of 10 nucleosides (uracil, uridine, 2'-deoxyuridine, inosine, guanosine, thymidine, adenine, adenosine, 2'-deoxyadenosine cordycepin) in populations Cordyceps cicadae, order to compare four Ophicordyceps sinensis one population militaris. Statistical analysis system (SAS) 8.1 was analyze nucleoside data. The pattern distribution analyzed sampled C. O. militaris, using descriptive statistical analysis, nested Q...

Gallic acid is one of the important polyphenols in plants and it inhibits α-amylase. The interaction between gallic α-amylase was investigated by fluorescence quenching spectroscopy, UV-vis synchronous three-dimensional spectroscopy under mimic physiological conditions. result emission at different temperatures revealed that there are static intrinsic induced a complex acid-α-amylase formed. results obtained from evaluation spectra, spectra suggested association did change molecular...

Panax notoginseng has been extensively used as a traditional Chinese medicine. In the current study, molecular cloning and characterization of PnbHLH1 transcription factor were explored in notoginseng. The full length gene obtained by splicing was 1430 bp, encoding 321 amino acids. Prokaryotic expression vector pET-28a-PnbHLH1 constructed transferred into BL21 prokaryotic strain. An electrophoretic mobility shift assay protein binding to E-box cis-acting elements verified that belonged bHLH...

Currently, the authentication of virgin walnut oil (VWO) has become very important due to possible adulteration VWO with cheaper plant oils such as soybean (SO), puer tea seed (PO), and sunflower (SFO). Methods involving Fourier transform infrared (FT-IR) spectroscopy combined chemometric techniques (partial least square) were developed for quantification SO, PO, SFO in VWO. IR spectra samples recorded at frequency regions 4000–650 cm −1 on horizontal attenuated total reflectance (HATR)...
