Spatial variability of hydrochemistry in coal-bearing karst areas considering sulfur pollution and underground engineering effects.

Coal-bearing karst areas are widely distributed around the world. Coal mining and tunnel construction significantly disturb the natural hydrological cycle and redox environment, leading to spatial variability in hydrochemistry and environmental pollution. Common environmental pollution in coal-bearing karst regions is the elevated sulfate content and the effusion of hydrogen sulfide.

Leachate reduction and pollution control strategies for landfills in hilly areas based on site condition analysis and numerical simulation.

Landfill is an important means of municipal solid waste treatment. Previous studies have shown that the combination of "cut-off wall and pumping well" technology is an effective measure to deal with the leachate emission reduction and pollution control of landfill, and has been widely used in plain areas. However, for landfills in hilly areas with complex terrain and geological conditions, there is still a lack of clear and referable ideas and operational strategies for leachate emission reduction and pollution control.

Health risk cause of water around landfill in hilly area and prevention and control countermeasures.

Evaluating the health risks of the groundwater and surface water in landfill areas is of great significance to the health and safety of local residents. The current practice of health risk assessment is based only on the analysis results of groundwater and surface water samples, which reflect the current situation of water security in landfill areas. However, due to the neglect of risk causes analysis, thus a health risk assessment is insufficient to provide rigorous scientific countermeasures for risk prevention and control.

Multi-therapies Based on PARP Inhibition: Potential Therapeutic Approaches for Cancer Treatment.

The nuclear enzymes called poly(ADP-ribose)polymerases (PARPs) are known to catalyze the process of PARylation, which plays a vital role in various cellular functions. They have become important targets for the discovery of novel antitumor drugs since their inhibition can induce significant lethality in tumor cells. Therefore, researchers all over the world have been focusing on developing novel and potent PARP inhibitors for cancer therapy.

Study on Regional Strata Movement during Deep Mining of Erdos Coal Field and Its Control.

Disasters such as rock bursts and mine earthquakes became increasingly serious with the increase in mining depth in Erdos Coal Field and became serious problems that restrict high-strength continuous mining of coal mines. In this study, strata movement and energy polling distribution of ultrathick weak-bonding sandstone layers were controlled by the local filling−caving multi-faces coordinated mining technique, which was based on the analysis of subsidence and overlying structural characteristics in the Yingpanhao mining area. Moreover, the influencing factors and the control effect laws were investigated.

The human health risk assessment and countermeasures study of groundwater quality.

Due to various geological, hydrogeological conditions and human activities, groundwater of different regions has distinct hydrochemical characteristics. The harmful chemical components of groundwater affect human health, and thus, the groundwater quality health risk assessment (GQHR) is important to local residents. It is vital to select GQHR factors combined with hydrochemical features, and to explore their formation, concentration characteristics and the prominent controlling role of influencing risk distribution from natural and human reasons.

Effects of the mechanical response of low-permeability sandstone reservoirs on CO geological storage based on laboratory experiments and numerical simulations.

Carbon dioxide (CO) geological storage (CGS) is an effective way for reducing greenhouse emissions. The injection of CO into the deep formation changes the pore pressure and effective stresses in the reservoir, thus leading to changes in stress-dependent porosity and permeability. These changes give feedback to the injection rate, migration, storage amount of CO in the target reservoir.

The robot is designed by the MR conditional criteria.

Reduced pests, improved grain quality and greater total income: benefits of intercropping rice with Pontederia cordata.

Background: Intercropping, which is growing two or more different crops in the same field simultaneously, is an effective traditional agricultural practice for productivity, resource utilization, and pest control. However, study on intercropping in paddy fields is limited. So in this study, field experiments of 2 years/four seasons (early and late seasons in 2016 and 2017) were conducted to examine the effects of rice-Pontederia cordata intercropping on rice plant growth, pest control, yield, income, and grain quality.

GABAergic System in Stress: Implications of GABAergic Neuron Subpopulations and the Gut-Vagus-Brain Pathway.

Stress can cause a variety of central nervous system disorders, which are critically mediated by the -aminobutyric acid (GABA) system in various brain structures. GABAergic neurons have different subsets, some of which coexpress certain neuropeptides that can be found in the digestive system. Accumulating evidence demonstrates that the gut-brain axis, which is primarily regulated by the vagus nerve, is involved in stress, suggesting a communication between the "gut-vagus-brain" pathway and the GABAergic neuronal system.

Clinical Outcomes of Sleeve Gastrectomy Versus Roux-En-Y Gastric Bypass After Failed Adjustable Gastric Banding.

Background: Over recent decades, laparoscopic adjustable gastric banding (LAGB) has been among the most common bariatric surgeries. Nowadays, many patients require revision surgery due to insufficient weight loss and band-related complications. Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the two most common revision surgeries for failed LAGB, but the conclusions about their efficacy and safety have been inconsistent.

Impacts of salinity on CO spatial distribution and storage amount in the formation with different dip angles.

Formation dip angle and the distortion of salinity affect the spatial distribution and storage capacity of carbon dioxide (CO). In this numerical study, based on an actual CO injection demonstration project (Shiqianfeng group in the Ordos Basin) in China, CO was injected for a period of 20 years at four different formation dip angles (0°, 5°, 10°, 15°). In conjunction, some salinity values were chosen, ranging from saturation salinity to no salinity.
