In this paper, a novel single fiber-type double cavity enhanced photoacoustic spectroscopy (SFDCE-PAS) sensor has been proposed and demonstrated for trace methane (CH <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> ) sensing. The mainly consists of Fabry-Perot (F-P) chamber, fiber-optic ceramic pin, polyethylene terephthalate (PET) film, (PA) cavity. PET film acts as an acoustic sensing unit the excitation light can transmit into PA...
The flavor of cigar tobacco leaf determines the quality finished tobacco, and enhancement generally relies on microbial fermentation. In this paper, correlation between dominant microorganisms main substances leaves during fermentation two were investigated to reveal metabolic pathways affecting substances. During process, flavors sweet, light grassy, with hexanal, 2,6-dimethylpyridine, nonanal, phenylacetaldehyde, naphthalene, methyl benzoate as constituents, key Haloferax mediterranei,...
Based on the sound intensity measurement and analyzing, noise radiated from washing machine with horizontal axis was discussed to identify source find its propagation path. According principle of measurement, grids were arranged at outside surfaces washer, distance set 20cm. The result showed that near right surface washer’s motor installing. maximum values are mainly in frequency bands 2 KHz 4 KHz. Back washer power level 51 dB value 55.8 for 56.0 There also appeared low 100 Hz Right...
A rotating fan could produce noise of both broadband and discrete frequency. The part typically consists shaft frequency, blade passage frequency (BPF) their higher harmonics. shaft-order noise, which is mainly induced by unbalanced rotating, often hard to be eliminated. In this paper, the caused geometric asymmetry discussed predicted. Analytic point force model firstly used predict at points in different directions. Then a hybrid method based on computational fluid dynamic (CFD) simulation...
Abstract Background: The implementation of the multi-cancer early detection (MCED) test offers a valuable adjunct to existing screening methods, enabling more efficient cancer and potentially leading improved treatment outcomes prognoses for patients. Here, we report on performance an MCED test, which utilizes plasma cfDNA leverages genome-wide fragmentomics-based characteristics identify signals predict signal origin across diverse range types. Methods: Plasma from evaluable blood samples...
Preparation of gradient porous membranes with stimulus-responsive, self-healing and UV-blocking properties.
Introduction: Thromboembolism is a recognized complication of nephrotic syndrome (NS). Evidence supporting the use rivaroxaban to prevent NS-related thrombosis limited and controversial. This study aimed explore impact NS on pharmacokinetics collect observational data efficacy safety as primary thromboprophylaxis in patients with NS. Methods: prospective analyzed 141 who received (10 mg/day) for thromboprophylaxis. High-performance liquid chromatography-tandem mass spectrometry was used...
Abnormalities in coagulation and fibrinolytic status have been demonstrated to be relevant inflammatory bowel disease. Nevertheless, there is no study methodically examine the role of fibrinolysis-related genes diagnosis ulcerative colitis (UC). UC-related datasets (GSE169568 GSE94648) were originated from Gene Expression Omnibus database. The biomarkers related fibrinolysis identified through combining differentially expressed analysis machine learning algorithms. Moreover, Set Enrichment...
<title>Abstract</title> With the continuous expansion of cigar tobacco consumer groups, sales domestic are rapidly rising, showing good development prospects, but at present, enhancement aroma quality raw materials is a major difficulty. In this study, macro-genomic technology was used to study mechanism protein degradation in leaves, aiming provide reference for that achieves fermentation effect through gene introduction into microorganisms. After 80 days natural fermentation, proteases...
An experimental measurement method used to build the two-port model of silencer based on least square (LSM) was developed here. The quantitative relationship between parameters transfer matrix and sound pressure measured at certain position in an duct system researched. A a are designed established validate method. procedures also referred. results match theoretical ones very well.
Temperature control is a key process in cigar fermentation. Aroma and sensory indicators are important for evaluating the quality of fermented cigars. In this study, volatile flavour components tobacco leaves during fermentation stage were analysed, with characteristic aroma screened using HS-SPME-GC-MS/O. To determine optimal temperature, comprehensive scores cigarette smoke at different treatment stages calculated principal component evaluation function. The results from olfactory network...
A method to calculate the radiation sound power from source characteristic of duct component is developed here; The relationship between and acoustical boundary conditions ends also researched by experiment. Based on two-port model, transfer matrix can be obtained numerical or experimental methods. calculation model predict at end system deduced component. simple validate setup measurement results are compared here as well.
The normal absorption coefficient of the multilayer material was studied in this research. A measurement duct system established at first, and then coefficients with different structures were measured through experimental system. Some conclusions could be drawn: Compared uniform material, multiple layer can change significantly without increasing thickness low frequency band. position area density aluminum plate both significantly. corresponding to absorbing peak value decreases plate....
The source Data of a duct system is studied in theoretical, experimental and numerical ways respectively. physical meaning the data obtained through theoretical derivation. model two-port acoustic established, have been measured by method "with an external source". insight parameter has demonstrated method. results shown that differences between pressures at specific locations inside will decrease gradually as boundary condition openings approximates ideal total absorption more more. larger...
