Natural gas hydrates represent a promising clean energy source with vast reserves. Their efficient development is crucial for ensuring the sustainable advancement of human society. However, wellhead instability occurred in long-term development, which poses significant challenge that impacts its commercial development. In present work, properties hydrate-bearing sediments were experimentally investigated. It was found elastic modulus, cohesion, and internal friction angle exhibit an increase...
A sustainable C(sp 2 )–C(sp 3 ) cross-electrophile coupling was developed between readily available 5-bromophthalide and 1-benzyl-4-iodopiperidine under micellar conditions, leading to a key intermediate of one our development compounds.
To investigate the productivity laws of coalbed gas (CBG) wells in carbon dioxide (CO2)-rich coalfield, Haishiwan coal mine Yaojie Gansu Province, China, which is rich CO2 different concentrations CBG, was selected as study area. Using numerical simulation technology, production capacity CBG simulated, and thermodynamic factors influencing adsorption differences on were discussed. Numerical indicates that with increase concentration, breakthrough time prolonged, first increases then...
In order to understand the kinetic characteristics of coal gas desorption based on pulsating injection (PI), research experimentally studied process methane in terms PI and hydrostatic (HI). The results show that curves HI are consistent with each other, diffusion model can best describe desorption. Initial velocity, capacity ultimate amount after greater than those HI, increases by 16.7–39.7%. Methane decay rate over time is less HI. influences parameters, it makes mass transfer Biot number...
The effect of postharvest 1-methylcyclopropene and/or cold storage application on texture quality parameters during was determined. changes in fruit (including weight loss, firmness, total soluble solids content, and ethylene production), cell wall material water-soluble fraction, ethylenediaminetetraacetic acid-soluble Na 2 CO 3 -soluble 4% KOH-soluble 14% fraction), hydrolase activities polygalacturonase, endo-1,4 -β-d-glucanase, pectinesterase, α-l-arabinofuranosidase, β-galactosidase)...
Five soluble polysaccharide fractions were sequentially extracted with water, EDTA, Na2CO3, 4% KOH, and 14% KOH solutions at room temperature for 4 h from cell wall material of rabbiteye blueberry (Vaccinium ashei) fruits, their physicochemical properties examined. The sequential treatments yielded a total 36.02% polysaccharides the dry material. HPAEC spectroscopy (FT-IR, NMR) analyses indicated that water-, EDTA-, Na2CO3-soluble mainly composed pectins, followed by lower amounts...
In order to reduce roof-floor blind area of hydrofracture in underground mines, expand influenced range fracturing, improve the effect hydrofracture, a pressure relief and permeability increase model hydraulic fracturing was built on basis analysing mechanism crack initiation characteristics fracture development. After discussing directional carrying out related numerical simulation, technique proposed. The coal development distribution rule process analysed, applied F15-31010 mining...
The optimum design of gas drainage boreholes is crucial for energy security and sustainability in coal mining. Therefore, the construction fluid–solid coupling models numerical simulation analyses are key problems boreholes. This work based on basic theory coupling, correlation definition between porosity permeability, previous studies influence adsorption expansion, change pore free pressure, Klinkenberg effect flow coal. A mathematical model dynamic evolution permeability derived....
Abstract The lower limb exoskeletons are used to assist wearers in various scenarios such as medical and industrial settings. Complex modeling errors of the exoskeleton different application pose challenges robustness stability its control algorithm. Radial Basis Function (RBF) neural network is widely compensate for errors. In order solve problem that current RBF controllers cannot guarantee asymptotic stability, a robust algorithm based on computed torque method proposed this paper,...
(1) Background: Soil salinity is one of the major abiotic stresses that limits plant growth and production. However, response patterns carbon metabolism to salt stress are still unclear. (2) Methods: We measured relative rate, non-structural carbohydrate (NSC) concentrations pool size across organs, leaf mass area (LMA), root-to-shoot ratio, midday water potential (Ψmd), photosynthetic characteristics elm seedlings planted in field under different intensities durations. (3) Results: Salt can...
