) adsorption increased to a large extent with the increase in TPD dose. Strong pH-dependence was observed in both Eu(
iii
) and Am(
iii
) adsorption processes, suggesting that inner-sphere complexes (ISCs) were possibly responsible for the adsorption of Eu(

) and Am(
iii
). Meanwhile, the adsorption of Eu(
iii
) and Am(
iii
) decreased to a different extent with the increase in ion strength, which was possibly related to outer-sphere complexes and/or ion exchange. In the presence of fulvic acid (FA), the adsorption of Eu(

In order to research the discharge properties of the direct carbon fuel cell (DCFC) with a molten metal anode, the experimental system with a reactor is designed and constructed. The reaction ...mechanisms at both anode and cathode are analyzed. The molten Sn and Sb are used as the anodic material for comparison. The cell performance of DCFC is tested before and after discharging in the battery mode and the carbon fuel mode, respectively. In the battery mode, due to the different states of metallic oxides, the current density is not degraded after discharging with the molten Sb anode, but sharply decreases with the molten Sn anode. On the contrary, the cell performance with Sb is much worse than that with Sn after discharging in the carbon fuel mode, which is result from the volatility of Sb together with the reduction of its oxide. The above studies will help to thoroughly understand the underlying mechanism of DCFC with a molten metal anode.
To detect the levels of KL-6 in the serum and the bronchoalveolar lavage fluid (BALF) of patients with different type of diffuse interstitial lung diseases(DILD), and to analyze its correlation with ...pulmonary function, pulmonary HRCT scores and other parameters.
Seventy-three patients with DILD were enrolled, including 34 patients with idiopathic pulmonary fibrosis (IPF), 10 patients with stage Ⅰ sarcoidosis(SAR Ⅰ), 15 patients with hypersensitivity pneumonia (HP), 14 patients with connective tissue diseases (CTD). Enzyme-linked immune sorbent assay (ELISA) was used to detect the levels of KL-6 in the serum and the BALF of these patients.
In the IPF group, FVC predicted percentage and DLCO predicted percentage were significantly lower than those of the SAR Ⅰ group(70±14)% vs (82±6)%, (49±13)% vs(81±6)%, P<0.05, but were no different compared to the CTD-ILD group(P>0.05). In the IPF group, the percentage of neutrophils in BALF was higher than that of the SAR Ⅰ group(9±7)% vs (6±4)%, P<0.05, and the percen
Abstract By analyzing 4.48 × 108 ψ(3686) events collected with the BESIII detector, we observe the decays χ cJ → nK S 0 Λ ¯ $$ {nK}_S^0\overline{\Lambda} $$ + c.c. (J = 0, 1, 2) for the first time, ...via the radiative transition ψ(3686) → γχ cJ . The branching fractions are determined to be (6.65 ± 0.26stat ± 0.41syst) × 10 −4, (1.66 ± 0.12stat ± 0.12syst) × 10 −4, and (3.58 ± 0.16stat ± 0.23syst) × 10 −4 for J = 0, 1, and 2, respectively.
Abstract Using 1310.6 × 106 J/ψ and 448.1 × 106 ψ(3686) events collected with the BESIII detector, the branching fractions of J/ψ decays to Σ+ Σ ¯ $$ \overline{\Sigma} $$ − is measured to be (10.61 ± ...0.04 ± 0.36) × 10 −4, which is significantly more precise than the current world average. The branching fractions of ψ(3686) decays to Σ+ Σ ¯ $$ \overline{\Sigma} $$ − is measured to be (2.52 ± 0.04 ± 0.09) × 10 −4, which is consistent with the previous measurements. In addition, the ratio of B $$ \mathcal{B} $$ (ψ(3686) → Σ+ Σ ¯ $$ \overline{\Sigma} $$ − )/ B $$ \mathcal{B} $$ (J/ψ → Σ+ Σ ¯ $$ \overline{\Sigma} $$ − ) is determined to be (23.8 ± 1.1)% which violates the “12% rule”.
To investigate the mid-to-long-term efficacy of patients with chronic ankle instability combined with posterior impingement syndrome after 3-9 years of follow-up, and to analyze the influencing ...factors.
From February 2010 to December 2015, 46 patients underwent concurrent lateral ankle ligament repair with posterior ankle arthroscopic surgery at the Institute of Sports Medicine, Peking University Third Hospital. The patient was first placed in a prone position and underwent arthroscopic debridement for the posterior impingement. After finishing the posterior arthroscopy, the surgeon and assistants first translated the patient to the affected side, then turned to the healthy side, and changed the position to the supine position. During the turning over, another assistant held the arthroscope and the instrument to ensure that it was sterile and could be used without replacement. The anterior ankle arthroscopy was operated if necessary and the lateral ankle ligament repair was anatomic repaired with anchors. The
In the carbonate reservoir, the fracture and cavity increased the gas break possibility easily. When the air was injected into the reservoir, the oxidation reaction changed the physical property of ...the crude oil and increased its viscosity. In this study, a physical modeling experiment was applied to analyze the in situ profile modification effect of oxidized oil by artificial fracture and cavity core. The results showed that the oxidation reactions increased the crude oil viscosity and reduced mobility ratio. The gas break phenomenon was suppressed in some degree.
