Recently, low power wireless sensor networks (LPWSNs) have been widely used in the military and education. However, lifetime of LPWSN is affected by energy sensor, so clustering design has received a lot attention. In this study, problem designing optimal for formulated as cluster head selection problem, considering energy, which an NP-hard problem. Therefore, new structural model constructed. This can represent process node information transfer. paper, immune chaotic adaptive evolutionary...

In traditional kerogen pyrolysis experiments, the effects of minerals and rock fabric on products were ignored. To further clarify role mineral matrix hydrocarbon generation retention, a closed anhydrous experiment was conducted core plugs, powdered from clay-rich sample Maoming oil shale within temperature range 312 °C to 600 °C, at fixed pressure 30 Mpa. The experiment’s results showed that yields heavy hydrocarbons (C14+) generated plugs obviously lower than kerogen, which may be caused...

Lack of soil moisture and phosphorus deficiency limits wheat grain yield in dryland areas. However, the moisture-conserving effect straw mulching combined with phosphor fertilization on fertile florets per spike (FFS) remains unclear. During 2020–2021 2021–2022 growing seasons, we investigated effects (0 8000 kg ha−1) (0, 75, 120 P2O5 development, assimilates’ availability, photosynthetic properties flag leaves by conducting a field experiment. Compared no mulch control, increased spike,...

To overcome strong drilling force and over high temperature during orthopedic surgery, the four medical drills with different geometrical shapes by using superhard materials were designed. The bone field of drill was theoretical analyzed. Results showed that brazed step has most ideal temperature. It controls maximum below 47°C even under dry drilling. twist is a little higher than 47°C. With appropriate cooling method, also could provide effect. On contrary, temperatures common drill,...

Straw mulching and N fertilization are effective in augmenting crop yields. Since their combined effects on wheat rhizosphere bacterial communities remain largely unknown, our aim was to assess how the respond these agricultural measures. We studied microbiomes a split-plot design experiment with maize straw (0 8,000 kg ha

In this study, an online antioxidant assay based on HPLC-ABTS was mainly developed for screening the antioxidants of flavonoids from Astragali Radix (AR), and comparing capacity between traditional decoction pieces (TDP) AR cell wall-broken (CDP) AR. The experimental results showed that overall CDP about twice as much TDP AR, which specifically expressed screened extracted equivalent to 1.9-5.1 times those TDP, three were successfully screened, calycosin-7-O-β-D-glucoside, calycosin,...

To examine the characteristic of denitrification in Frankia, a symbiotic nitrogen-fixing microbe associated with non-leguminous plants, and its role as N2O source or sink, Casuarina root nodule endophyte Frankia was isolated using sectioning method, which then purely cultured to investigate process under NO3- addition. The results showed that after addition medium anaerobic condition, concentration decreased time, while concentrations NO2- initially increased over time. Key genes nitrogenase...
