Photoacoustic spectroscopy has been proved to be a potential method for noninvasive blood glucose detection. We used 1535 nm pulsed laser excite photoacoustic signal in solution and then explored the influence of different concentration on analyze sensitivity at this wavelength. designed simple cell structure, which focused ultrasonic transducer receive signals, so as reduce attenuation. In terms results, we have found that high-concentration solutions, results strong linearity...
Reinforced concretes (RC) have been widely used in constructions. In construction, one of the critical elements carrying a high percentage weight is columns which were not to design absorb large dynamic load like surface bursts. This study focuses on investigating blast parameters more resistant RC loads. The numerical model based finite element analysis (FEA) using LS-DYNA. Numerical results are validated against field tests available online. Couples simulations performed with changing...
A new structure with negative stiffness and Poisson's ratio was designed to exhibit these characteristics during compression, energy absorption, storage. The also shows improved impact resistance under extreme conditions due transverse contraction compression. These make the very suitable for use in spacecraft landing systems. finite-element model using Auricchio constitutive established, compression tests were conducted on structure. test results are agreement simulation, validating model....
In this study, 112 traditional villages in volcanic areas of Hainan Province were investigated. The field investigation, spatial analysis, statistics and comparative study on the vernacular dwellings performed. Based theory ecological adaptability, layout types, distribution differences studied from perspective village structure, architectural space form construction mode. It is found that natural environment, functions, customs, national culture other aspects are fundamental reasons for...
Identifying useful taxonomic indicators for classifying Hibiscus syriacus L. (Malvaceae) cultivars can help address challenges in their homonymy and synonymy. Moreover, analyzing which pollen traits possibly lead to successful fruiting serve guide the hybridization breeding of H. syriacus. For first time, this study classified 24 based on morphological palynological assessed flowers, leaves, grains. These were a mixture quantitative qualitative traits, measured contribute identification...
Abstract Background Fetal growth velocity standards have yet to be established for the Chinese population. This study aimed establish such suitable Methods We performed a multicenter, population–based longitudinal cohort including 9075 low–risk singleton pregnant women. Data were collected from clinical records of 24 hospitals in 18 provinces China. Demographic characteristics, reproductive history, fetal ultrasound measurements, and perinatal outcome data collected. The measurements...
The ore transportation system of strip mines is a representative discrete-event sys-tem, so the data concerning facilities and resource are collected extracted to obtain their statistical probability by Expertfit; Based on Flexsim, Then 3D model developed, incarnating relationship among transport, facilities, thereby, which vividly simulates, anal sizes optimizes producing-transport mines.It puts forward two dispatching method, Grade-threshold Passive-Dispatched Truck, sets three indexes in...
The optimum cost of a reinforced concrete plane and space frames have been found by using the Genetic Algorithm (GA) method. design procedure is subjected to many constraints controlling designed sections (beams columns) based on standard specifications American Concrete Institute ACI Code 2011. variables contained dimensions sections, steel topology through section. It obtained from predetermined database containing all single for beam columns axial load, uniaxial or biaxial moments. GAs...
Dual-energy X-ray absorptiometry (DXA) machines based on bone mineral density (BMD) represent the gold standard for osteoporosis diagnosis and assessment of fracture risk, but strength toughness are strongly correlated with collagen content (CC). Early detection combined BMD CC will provide improved predictability avoiding risk. The backscattering resonance (BR) phenomenon is present in both ultrasound (US) photoacoustic (PA) signal transmissions through bone, peak frequencies BR can be...
The optical fibre endoscope with cold light is still mainstream in the market, but inherent structural characteristics of lead to its shortcomings, such as high price, inconvenient carry, and easy distortion image. micro medical electronic can receive front-end system image through miniature CCD (Charge Coupled Device) transmit display cable, which greatly solves limitations endoscope. In this paper, using ZEMAX software, an imaging 75∘ field view designed. consists four lenses, all...
Abstract Objective To build a reference fetal growth chart for the Chinese population based on ultrasound measurements. Methods This was multicenter, population-based retrospective cohort study. Longitudinal measurement data were collected from 24 hospitals in 18 provinces of China 1 st September through 31 October 2019. The estimated weight (EFW) calculated head circumference, abdominal and femur length using Hadlock formula 3. Fetal curves two-level linear regression model with cubic...
