Overall, our work showed that application of BIO does not alter the main community structure and functional diversity of soil bacteria in rice paddies and should be encouraged for use as a sustainable weed management strategy.Between 1973 and 2017, evidences of red tide outbreaks and oil spill accidents in the Chinese coastal waters were collected. Statistical analysis and multiple regression models were used to determine the relationship between the red tide and the oil spill. Major findings reveal that (1) the frequency of red tides positively correlates to the number of oil spills and the volume of oil spilled as well; (2) the higher percentage of small spills ( less then 7 tonnes) are more likely to enhance the outbreaks of red tides; (3) both EI Niño and storm events do not show any relationship with red tides; and (4) more severe oil spill with penalty recorded implies a higher possibility to trigger the red tide afterwards. Therefore, oil spill contingency management focusing on small oil spills and mitigating their spill effect by physical measures could be of benefit to decrease the frequency of red tides significantly. For example, it is suggested to carry out physical combat instead of chemical dispersants to remove the spilled small oil in the shallow coastal areas for reducing the outbreak risk of red tides after the oil spill.Denitrifying phosphorus removal was realized in sequencing batch reactors using different carbon sources (acetate, propionate, and a mixture of acetate/propionate). Nutrient removal and nitrous oxide (N2O) production were investigated, and the factors affecting N2O production were explored. Nitrogen removal was 40.6% lower when propionate was used as the carbon source instead of acetate, while phosphorus removal was not significantly different. N2O production was greatly reduced when propionate was used as the carbon source instead of acetate. The emission factor in the propionate system was only 0.43%, while those in the acetate and mixed-carbon source system were 16.3% and 1.9%, respectively. Compared to the propionate system, ordinary heterotrophic organisms (i.e., glycogen-accumulating organisms) were enriched in the acetate system, explaining the higher N2O production in the acetate system. The lower nitrite accumulation in the propionate system compared to the acetate system was the dominant factor leading to the lower N2O production.Is rapid urban sprawl increasing environmental pollution while boosting economic development? This study uses panel data of 30 Chinese provinces during 2002-2018 to investigate the impact of urban sprawl on haze pollution with the use of a spatial lag model. Urban built-up area (ba) and urban public facilities occupation (upfo) are used to measure the differential impact of urban sprawl on haze pollution. The main highlights of the results are as follows (1) there is a nonlinear relationship between urban sprawl and haze pollution. An inverted U-shaped relationship was found between built-up area and haze pollution, while urban public facility occupation and haze pollution have a U-shaped correlation. (2) The impact of urban sprawl on haze pollution shows a significant time-based difference. The relationship between the two was not significant in 2002-2010, but become significant in 2011-2018. (3) Significant regional differences in the impact of urban sprawl on haze pollution were found. The effects of urban sprawl on urban haze levels are more pronounced in the eastern and western regions than in the central region.Catalytic combustion of propane as typical light alkanes was important for the purification of industrial VOCs and automobile hydrocarbon emissions. Si-doped Al2O3 nanosheet was synthesized by a hydrothermal method, and effects of Si content on the morphology and thermal stability of Al2O3 were investigated. The doping of SiO2 could tune the thickness of Al2O3 nanosheets and significantly improve its thermal stability, the θ phase was still maintained, and the specific surface area was as high as 56.3 m2 g-1 after calcination at 1200 °C. Z-VAD-FMK And then the Si-doped Al2O3 nanosheets were used as support of Pd catalysts (Pd/Si-Al2O3 nanosheets) for catalytic combustion of propane, especially Pd/3.6Si-Al2O3 nanosheets, which presented high activity, stability, and resistance to sintering and H2O due to the promotion of Si on the thermal stability of Al2O3 and the stabilization (dispersion, isolation, and strong interaction) of PdOx species.As part of the most used herbicides, glyphosate is the most successful ingredient of agrochemical companies. The main objective of this study was to demonstrate research trends related to the glyphosate toxicity and its main effects on human and environmental health. For this purpose, 443 articles published, from 1995 to 2020, on the platform Web of Science™ Thomson Reuters were selected. The main toxicity results related in literature are genotoxicity, cytotoxicity, and endocrine disruption. The environmental effects come mostly from the contamination of groundwater and soils. Several studies have concluded that herbicide concentrations right below the official safety limits induced toxic effects. The results presented a highlighted harmful effect of glyphosate on both human and environmental health. link2 It has been observed that countries where publish the most about the glyphosate toxicity are great investors in large-scale agriculture. It is important to ponder that these countries are in a route of ecosystem exploitation that includes not only fauna and flora, but also human beings. link3 Unfortunately, science does not provide concise data for these pesticide disapproval in the global consumer market. It is necessary to search sustainable global interest alternatives to increase agriculture production based on peoples' food sovereignty.The effective removal of strontium from polluted water is an emerging issue worldwide, especially in Japan, after the destruction of Fukushima's Daiichi Nuclear Power Plant. In the strontium removal process, statistical optimization of associated factors is needed to reduce the quantity of chemicals and the number of experimental trials. In this study, response surface methodology based on the central composite design was employed for assessing the influence of different factors and their interaction effects on the efficiency of strontium removal. We have considered nanoscale zero-valent iron-zeolite (nZVI-Z) and nano-Fe/Cu zeolite (nFe/Cu-Z) as adsorbents for the effective removal of strontium. The results suggested that the studied three factors such as pH, contact time, and concentration are positively related to the adsorption of strontium. That is, the maximum strontium removal occurred at pH, initial concentration, and contact time of 12, 200 mg L-1, and 30 min, respectively. The experimental maximum strontium adsorption capacity of nZVI-Z and nFe/Cu-Z adsorbents is 32.5 mg/g and 34 mg/g, respectively. The present study also showed that the most statistically significant potential contributor was initial concentration, followed by contact time in the removal process. The study indicated that the interaction effect between contact time and initial concentration was statistically important, suggesting the need for a multi-mechanism technique in the removal phase of strontium. Tόth, Langmuir, Dubinin-Astakhov (D-A), Freundlich, and Hill isotherm models were also fitted with the experimental strontium adsorption data, in which the Tόth model fitted best compared to the other models based on the RMSD and R2.The distribution of voltage in sub-micron cellular domains remains poorly understood. In neurons, the voltage results from the difference in ionic concentrations which are continuously maintained by pumps and exchangers. However, it not clear how electro-neutrality could be maintained by an excess of fast moving positive ions that should be counter balanced by slow diffusing negatively charged proteins. Using the theory of electro-diffusion, we study here the voltage distribution in a generic domain, which consists of two concentric disks (resp. ball) in two (resp. three) dimensions, where a negative charge is fixed in the inner domain. When global but not local electro-neutrality is maintained, we solve the Poisson-Nernst-Planck equation both analytically and numerically in dimension 1 (flat) and 2 (cylindrical) and found that the voltage changes considerably on a spatial scale which is much larger than the Debye screening length, which assumes electro-neutrality. The present result suggests that long-range voltage drop changes are expected in neuronal microcompartments, probably relevant to explain the activation of far away voltage-gated channels located on the surface membrane.

Despite the limited research in support of robotic inguinal hernia repair (RIHR), it is an increasingly adopted technique in surgical practice. While a major risk factor for the development of ventral hernias and subsequent complications, obesity in RIHR has not been investigated. The aim of this study was to compare the outcomes of RIHR between obese and non-obese patients.

Prospectively collected data surrounding RIHRs performed at a single center between 2013 and 2020 were retrospectively reviewed. Patients were divided into non-obese (< 30kg/m

) and obese (≥ 30kg/m

) groups, and preoperative, intraoperative, and postoperative variables were compared in unmatched and matched groups, derived using a 12 propensity score match (PSM).

From a total of 547 patients, 414 were non-obese and 133 were obese. A PSM analysis, accounting for confounding preoperative variables and risk factors, stratified these into 262 patients for the non-obese group and 131 patients for the obese group. Although the obese tive BMI threshold exists for RIHR.

The objective was to assess the effectiveness and safety of a bioabsorbable mesh at the time of closure of a midline laparotomy for IH prevention.

A multicenter, randomized clinical trial including patients undergoing abdominal surgical procedures through a midline laparotomy incision was designed. In the group of mesh (n=167) the incision was closed using a continuous polydioxanone suture (PDS) plus a bioabsorbable mesh. In the control group (n=165) a continuous PDS single layer suture was only used. Patients were randomly assigned (11) to the two groups. The primary outcome was the incidence of IH at 6, 12 and 24 months. Assessment of IH was done using a CT scan.

At 6 months, the rates of IH were 15.2% and 24.8% in the experimental and control groups, respectively (relative risk [RR] 0.66, 95% confidence interval [CI] 0.38-0.98, P = 0.042). At 12 months, the rate of IH continued to be significantly lower in the experimental group (21.4% vs. 33.1%, P = 0.033), but at 24 months, there were no significant differences between the study groups with a follow-up rate of only 37.5%. The number needed to treat (NNT) was 11 and 9 at 6 and 12 months, respectively.

The bioabsorbable mesh significantly prevented IH during the first year. Not reliable conclusions can be drawn across the second year. This may suggest that the any of the closing technique assessed in this study would have a "palliative" transient effect for preventing IH in the long-term.
