To address the issues of plume formation and heavy metal ion release during deep-sea mining operations, this study employed multi-sourced mineral composite roasting materials (MMCCM) of varying sizes. An in-situ capping technique was applied within a simulated system to immobilize heavy metals in contaminated sediments. The results demonstrated that capping with MMCCM of different sizes significantly suppressed the upward migration of Cu, Co, and Ni from sediments into the overlying seawater following disturbance.

Oil, mineral processing and environmental restoration can be dangerous processes. Attempts are often made to apply microorganisms to reduce the risks, but the adaptability of terrestrial organisms is often weak. Although genetically engineered strains can improve their environmental adaptability through targeted modification, there are problems such as metabolite accumulation, poor plasmid stability and potential pathogenicity.

This research focuses on the issue of heavy metal release during mining activities. Through simulation experiments, we investigated the release of Cu, Co, and Ni from sediments under disturbance conditions and the fixation behavior during the deployment of ocean manganese nodule-sodium alginate composite microspheres (OMN@SA).

Biological treatment methods have obvious advantages, but the existing microorganisms exhibit issues such as poor resistance, adaptability, colonization ability, and low activity. However, a wide variety of microorganisms in deep-sea hydrothermal vent areas are tolerant to heavy metals, possessing the potential for efficient treatment of heavy metal wastewater.

Recently, perception task based on Bird's-Eye View (BEV) representation has drawn more and more attention, and BEV representation is promising as the foundation for next-generation Autonomous Vehicle (AV) perception. However, most existing BEV solutions either require considerable resources to execute on-vehicle inference or suffer from modest performance. This paper proposes a simple yet effective framework, termed Fast-BEV, which is capable of performing faster BEV perception on the on-vehicle chips.

We applied a risk-benefit assessment (RBA) model that took into account the health effects of selenium (Se), cadmium (Cd), and inorganic arsenic (i-As). The health effects included the prevention of prostate cancer associated with exposure to Se, and an increased risk of lung, bladder, and skin cancer for i-As and chronic kidney disease (CKD) for Cd.

Objective: To investigate the effect of active immunization on prevention of post-transplantation de novo hepatitis B virus (HBV) infection in patients receiving liver grafts from hepatitis B core antibody (HBcAb) positive donors.
Methods: A retrospective analysis was conducted. Eighty-seven children undergoing liver transplantation from HBcAb positive donors admitted to Tianjin First Center Hospital from October 2012 to December 2016 were enrolled, and the data of donors and recipients were collected.

Objective: To investigate the protective effects of resveratrol on brain tissues in aging mice induced by D-galactose.
Methods: 54 Kunming male mice aged 16 weeks were randomly divided into control group, aging group, intervention group. The control group was prepared by subcutaneous injection of normal saline and the other two groups were prepared by subcutaneous injection of D-galactose(200 mg/kg BW).
Recently, interest is growing to explore low-cost and sustainable means of energy production. In this study, we have exploited the potential of sustainable energy production from wastes. Activated sludge and algae biomass are used as substrates in microbial fuel cell (MFC) to produce electricity.
