Nutrient dynamics in lakes are determined by the external anthropogenic discharges and unobserved internal cycling processes. In this work, a decadal nutrient data set from eutrophic Lake Taihu, China, revealed strong seasonal pattern of concentration limitation. A nutrient-driven dynamic eutrophication model based on Bayesian hierarchical framework was established to quantify relative contributions temporal variations Results showed that after years efforts reduction, were relatively small...
Teinturier grapes are characterized by the typical accumulation of anthocyanins in grape skin, flesh, and vegetative tissues, endowing them with high utility value red wine blending nutrient-enriched foods developing. However, due to lack genome information, mechanism involved regulating teinturier coloring has not yet been elucidated their genetic utilization research is still insufficient. Here, cultivar 'Yan73' was used for assembling telomere-to-telomere (T2T) combining High Fidelity...
Wave–current interaction over the Texas–Louisiana shelf, and its effects on dispersal mixing of Mississippi–Atchafalaya river plume, have been investigated using Coupled Ocean–Atmosphere–Wave–Sediment Transport (COAWST) Modeling System. The modeling system is driven by realistic wave current conditions at open boundaries high frequency1-D wind measured from a nearby meteorological station. Skill analysis demonstrates that model reproduces salinity fields reasonably well. Waves shelf are...
The main sensitivity parameters of the Holmquist–Johnson–Cook constitutive model for coal were obtained from a variety tests such as uniaxial compression, cyclic loading, splitting and triaxial compression tests, well indirect derivation equation briquette. mechanical properties briquettes under dynamic impact investigated using split Hopkinson pressure bar experiment. Based on experimental measurement model, numerical simulation briquette was performed ANSYS/LS-DYNA software. A comparison...
Abstract The magnetic target location technology based on the principle of gradient tensor has broad engineering application prospects. However, commonly used positioning methods are easily interfered with by geomagnetic environment. We proposed a nonlinear method to achieve precise localization objects. An ellipsoid fitting total least square algorithm is correct measurement system’s interference and array error. results show that can reduce root mean error field strength 93.05% 0.1007 uT....
The secondary lining failure of deep buried soft rock tunnel often occurs, which is obviously related to the time factor. formation mechanism this phenomenon studied in paper. Therefore, combination situ stress measurement and neural network inversion used analyze distribution characteristics stress. At same time, creep surrounding are tested laboratory, key parameters obtained. Combined with rock, calculation model established by using discrete element simulation technology considering...
Excavation-induced unloading effects and dewatering-induced groundwater seepage inevitably result in basal soil reverse consolidation deep excavation. However, this process is rarely considered because most previous analytical methods were developed based on total stress analyses. This study proposes a one-dimensional model for of Based the theory proposed by Terzaghi, governing equations caused excavation dewatering separately established. The continuous drainage boundary was introduced to...
Coal and gas outburst is a serious disaster in the mining, crosscut coal most prone to cause outburst. In order study mechanism of outburst, this paper studied stress distribution characteristics front working face process rock roadway driving before implementing firstly. On basis, hypothesis on “strong soft face” coal-rock mass was proposed. And by using hypothesis, mechanical equation for parameter changes plastic zone established, width morphological were analyzed. The results show that...
The diffusion coefficient of gases in coal varies with time. This study aims to develop an unsteady dynamic (UDD) model based on the decay time and change integral. conducted a series gas desorption experiments three different combinations particle sizes pressures compared coefficients models. UDD exhibited good fitting results, both bidisperse models fitted experimental data better than unipore model. In addition, (DDe) decreased rapidly initial stage but gradually stable level later stage....
A reasonable and precise preventive maintenance period can effectively reduce the repair frequency cost of equipment maintenance. The serious breakdown slow convergence often appear when using ASO (Ant Colony Optimization) PSO (Particle Swarm in optimization problem. Regarding these problem, a model was established concerning with concept age reduction factor optimized by AFSA (Artificial Fish School Algorithm). Based on solution AFSA, this paper focus change system's total benefit which is...
Mine earthquake, as an underground disaster that occurs frequently, has a great impact on coal mine roadway and support. The stability analysis of the bolt support in under different earthquake magnitudes is key issue to be solved urgently mining fields. This paper attempted simulate occurrence state with explosive blasting process verified it actual microseismic monitoring data. ANSYS/LSDYNA software was used analyze magnitude location hypocenter dynamic stress characteristics bolt. results...
