vestigation. A standardized recommendation based on research and data derived from Chinese patients is required. Ultrasound guidance does not eliminate the risk of intraneural injection, which must be avoided during PNB. Combining ultrasound guidance (USG), nerve stimulation (NS), and injection pressure monitoring is advocated to prevent nerve injury during PNB. We hypothesized that combining patient-tailored dynamic NS and real-time pressure sensing (RTPS) could reduce the incidence of intraneural injection and nerve puncture during USG PNB compared with a traditional fixed thresholds (Control) procedure. Randomized, prospective study. Operating room. One hundred ASA physical status I to III patients undergoing orthopedic surgery. Patient anesthetized using axillary, sciatic or femoral USG PNB were randomized to the PresStim group (Dynamic RTPS and NS set at 1.5mA then decreased; n=50) or Control group (fixed thresholds for in-line pressure mechanical manometer and NS at 0.2mA; n=50). Procedural ultrasound images and videos were recorded, stored and reviewed in random order by two experts in ultrasound-guid conditions of the study, dynamic triple monitoring combining RTPS, NS and USG decreases intraneural injection and unintentional needle-nerve contact and puncture during a PNB procedure.This study investigated the changes of phosphorus (P) fractions, bacterial community and their response to available P or carbon (C)P during composting with different rock phosphate (RP) addition levels. Results showed that adding RP at 10% or 15% promoted the rise of temperature, maturity and Olsen P accumulation in composting, which had a higher amount of RP solubilization than other groups. Available P changed bacterial composition and decreased diversity in composts. RP solubilization efficiency was negatively correlated to CP ratio and the highest (22.7%) when 10% RP was added, in which bacterial community changed from "function redundancy" to "intensive P-solubilization". Low CP ratio (〈300) increased the RP solubilization ratio especially within 135-160. PT2385 Therefore, this study proposed that adding P-rich substrates to decrease CP ratio could regulate P-solubilizers' activity for increasing RP solubilization efficiency during composting.In this study, a simple two-step hydrothermal method was used to prepare the cathode catalyst of the microbial fuel cell (MFC). NiCoAl- layered double hydroxide (LDH) nanosheets were grown vertically on multi-wall carbon nanotubes (MWCNTs) in situ; Ni-catecholate-based metal organic framework (Ni-CAT MOF) were modified on the surface of the nanosheets. The maximum output voltage of Ni-CAT/NiCoAl-LDH/MWCNTs was 475 mV, the maximum stabilization time was 8 d, the maximum output power was 448.5 ± 12.0 mW/m2, which was 1.03 times that of NiCoAl-LDH/MWCNT-MFC (433.5 ± 14.8 mW/m2) and 1.35 times of NiCoAl-LDH- MFC (329.9 ± 2.9 mW/m2). The layer structure of LDH, conductivity of Ni-CAT and MWCNT improved the flow efficiency of ions between layers and effectively reduced transmission resistance, and these have effectively enhanced the cycle stability and power generation efficiency of the electrode.Magnetic hydrochar modified by β-cyclodextrin (β-CD) described as β-CD@MHC was successfully synthesized and applied to simultaneous removal of cadmium (Cd) and anthracene (ANT). Characterizations attested the grafting of β-CD groups onto β-CD@MHC with excellent magnetism. Moreover, the β-CD@MHC could eliminate Cd(II) and ANT during an extensive pH scope, and presented fast adsorption equilibrium in 60 min and 80 min for Cd(II) and ANT, respectively. And the β-CD@MHC possessed prominent adsorption properties with maximum monolayer binding of 47.28 mg/g for Cd(II), and corresponding heterogeneous uptake of 60.27 mg/g concerning ANT. Furthermore, the β-CD@MHC could effectively avoid the competitive behavior between Cd(II) and ANT mainly due to complexation and electrostatic attraction effects for capturing Cd(II), and host-guest interaction in the removal of ANT. Additionally, the binding of Cd(II) and ANT onto β-CD@MHC dropped slightly after stepwise desorption, suggesting the β-CD@MHC as a high-performance adsorbent for heavy metals and PAHs elimination from wastewater.Cheese whey is an abundant and low-cost feedstock with lactose as its main component, but the inability to metabolize lactose prevents Aureobasidium pullulans from using cheese whey directly. In this study, Kluyveromyces marxianus was permeabilized to obtain nonviable but biocatalytic cells for lactose hydrolysis, and the mixed culture of A. pullulans and permeabilized K. marxianus was conducted for polymalic acid (PMA) production from cheese whey. In the mixed culture, PMA titer varied directly to β-galactosidase activity of K. marxianus, but inversely to cell viability of K. marxianus, and ethanol permeabilized K. marxianus was the most compatible with A. pullulans for PMA production. 37.8 g/L PMA was produced in batch fermentation, and PMA titer was increased to 97.3 g/L in fed-batch fermentation, with a productivity of 0.51 g/(L·h) and a yield of 0.56 g/g. This study paved an economical and environmentally friendly way for PMA production from cheese whey.In this work, hickory chip biochars developed at distinctive pyrolysis temperatures were ball milled (BMHC) and then post-modified with a 10% hydrogen peroxide (H2O2) solution to obtain a set of novel sorbents (BMHC-H2O2). The specific surface area (SSA) was dramatically increased after ball-milling while the hydroxyl and carboxyl groups on the surface of the biochars were further increased through H2O2 modification. Additionally, thermal stability of the biochar treated with ball-milling was not greatly reduced by H2O2 modification and hydrodynamic radius was decreased. Ball milling enhanced the adsorption efficiency to methylene blue (MB) by the biochar, and this ability was further increased by H2O2 modification, because of the increasing in oxygen-containing functional groups (OCFG) to interact with MB. The rate of MB adsorption to BMHC-H2O2 was faster than that of BMHC, reaching equilibrium after about 6 h. Among adsorbents tested, the 450 °C BMHC-H2O2 had the greatest MB adsorption capacity (310 mg g-1).
