Abstract Much effort has been devoted to studying the absorption of anthropogenic CO 2 by surface and subsurface ocean, where seawater acidifies rapidly while deep ocean was thought respond intrusion at longer time scales. However, recent studies have revealed rapid acidification Japan/East Sea, implying that ongoing changes in dynamics are accelerating depth, controlling mechanisms not fully addressed. Using a multibox model circulation carbonate chemistry, we demonstrate combination...
In this study, response surface methodology (RSM) was used to optimize the ultrasonic-assisted extraction parameters of Sojae Semen Praeparatum polysaccharides (SSPP-80), optimum conditions were determined as follows: ultrasonic frequency 100 W, power 80 Hz, temperature 52℃, time 23 minutes, and liquid raw material ratio 40 mL/g. Based on these conditions, rate 7.72% ± 0.26%. Then, 2 novel (SSPP-80‐1, SSPP-80‐2) isolated from SSPP by DEAE-cellulose 52 chromatography. The chemical...
Abstract The critical role of marginal seas in the global carbon cycle and their response to climate circulation changes are not well understood. In this study, we used long‐term archives sedimentary CaCO 3 data a conceptual model systematically determine spatial vertical features sediment carbonate system along Western Pacific Ocean. Our results show that northward‐flowing Antarctic Bottom Water Lower Circumpolar Deep produced shallower calcium preservation depths as they moved north became...
A simple, highly sensitive ion chromatographic method for the simultaneous determination of betaine, choline and carnitine in feed premixes is described. Premixes were extracted via ultrasonication water 20 min extracts analyzed by chromatography using an aqueous 3.0 mmol L−1 methane sulfonic acid solution containing 15% (v/v) acetonitrile as eluent IonPac SCS1 column. The composition mobile phase was optimized efficient separation three main analytes from each other well common inorganic...
This study evaluated the effects of phosphorus restriction in brooding stage and subsequent recovery on growth performance, tibia development early laying performance layers. 360 one-day-old hens were randomly divided into 4 groups with 6 replicates 15 chicks per replicate. Chicks fed diets containing 0.13% (L), 0.29% (M), 0.45% (N), 0.59% (H) non-phytate (nPP) from 1 to 8 weeks age. From 9 20 age, L N group two normal level (n, 0.39% nPP) high-level (h, separately, then all birds a diet...
A rapid and simple method was established for the determination of acidic dyes in pharmaceutical capsules using solid-phase extraction high-performance liquid chromatography with a diode array detector. The were dissolved water an ultrasonic bath at 55 ± 5°C, pH adjusted to 1 0.2 mol/L hydrochloric acid. resulting solution purified weak anion exchange cartridge. Chromatographic separation performed on reversed phase C18 column gradient elution acetonitrile 20 mmol/L aqueous ammonium acetate...
Abstract Taking Valerianrhizome as raw material and the yield of volatile oil Valerian an index, extraction process valerian was analyzed by microwave assisted steam distillation, optimized Box-Behnken response surface test. The effects scavenging capacity Li, DPPH hydroxyl radicals on their antioxidant were studied. results showed that optimal conditions 350W power, time 25min, liquid-to-material ratio 8.8mL: 1.0g, extracted under this condition 5.88%. Microwave-extracted has strong ability...
Manchurochelys manchoukuoensis is a sinemydid stem-cryptodire turtle known by fossils from the Lower Cretaceous beds exposed in western Liaoning and Inner Mongolia of China. This fossil taxon important for understanding origin evolution Cryptodira (crown-group hidden-neck turtles). The holotype M. was presumably lost during Second World War several aspects osteology species remains unknown. We here describe near-complete skeleton coming Yixian Formation, Liaoning, China, 50 km away type...
