Abstract

Risk-taking behavior is particularly widespread during adolescence, and negatively impacts the healthy growth and social adaptation of adolescents. Utilizing problem-behavior theory (PBT) and the family stress model (FSM), the current study examined the relationship between socioeconomic status (SES) and adolescents’ risk-taking behavior, as well as the mediating role of psychological capital and self-control. A total of 1,156 Chinese adolescent students (Mage = 15.51, 48% boys) completed a series of questionnaires anonymously. The results showed that: (1) Socioeconomic status was negatively correlated with adolescents’ risk-taking behavior; (2) Both psychological capital and self-control mediated the relationship between SES and adolescents’ risk-taking behavior independently; and (3) Psychological capital and self-control also mediated the relationship between SES and the risk-taking behavior of adolescents sequentially. This study reveals the internal mechanism of risk-taking behavior during adolescence and provides theoretical support and empirical evidence for preventing and reducing such behavior in this age group.

Abstract

A microbial consortium which can efficiently remove hexabromocyclododecane (HBCD) under anaerobic condition have been successfully enriched over 300 days. Under the optimal conditions, the degradation efficiency was 92.4% removal after treatment of 12 days with original addition of 500 μg/L HBCD, yielding 321.7 μg/L bromide in total as well. A typical debromination product, dibromocyclododecadiene (DBCD), was detected during the degradation process. The debromination profiles of three main HBCD diastereomers fitted well with first-order model (R2: 0.96–0.99), with the rate constants ranging from 1.3 × 10-1 to 1.9 × 10-1. The microbial community analysis by high throughput sequencing showed that the composition of the microbial communities varied dynamically with time and the population of functional bacteria increase sharply after enrichment. The population of Bacteroidetes increased from 5 to 47%. And some bacteria which are relatively minority in population at the beginning, such as Azospira oryzae (OTU2), Microbacterium (OTU13), and Achromobacter insolitus (OTU39) increased more than 22 times after enrichment (from 0.5 to 13%, 12%, and 11%, respectively). However, no reported dehalogenating bacteria were found after enrichment. And the contribution for debromination may come from new dehalogenating bacteria. All in all, the present study provided in-depth information on anaerobic microbial communities for HBCD removal by debromination.

Abstract

BACKGROUND: The complex characteristics and unclear biological fate of biomacromolecules (BMM), including colloidal and soluble microbial products (SMP), extracellular polymeric substances (EPS) and membrane surface foulants (MSF), are crucial factors that limit our understanding of membrane fouling in membrane bioreactors (MBRs). FINDINGS: In this study, the microbial transformation of BMM was investigated in a lab-scale MBR by well-controlled bioassay tests. The results of experimental measurements and mathematical modeling show that SMP, EPS, and MSF had different biodegradation behaviors and kinetic models. Based on the multi-exponential G models, SMP were mainly composed of slowly biodegradable polysaccharides (PS), proteins (PN), and non-biodegradable humic substances (HS). In contrast, EPS contained a large number of readily biodegradable PN, slowly biodegradable PS and HS. MSF were dominated by slowly biodegradable PS, which had a degradation rate constant similar to that of SMP-PS, while degradation behaviors of MSF-PN and MSF-HS were much more similar to those of EPS-PN and EPS-HS, respectively. In addition, the large-molecular weight (MW) compounds (>100 kDa) in BMM were found to have a faster microbial transformation rate compared to the small-MW compounds (

Abstract

Aerobic and anaerobic continuous stirred-tank reactor (CSTR), up-flow anaerobic sludge blanket (UASB) were set up and inoculated with newly isolated Candida tropicalis. Reactors were operated at high concentrations of chemical oxygen demand (COD) (8000 mg/L), the modified UASB expressed better COD removal rate simultaneously removal of nitrogen and phosphate than other two reactors. Notably, under both aerobic or anaerobic conditions, large amounts of organic acids and alcohol were generated. Transcriptomic analysis showed that carbon metabolism under anaerobic conditions shared the same pathway with aerobic conditions by regulating and inhibiting some functional genes. Experiments utilizing different carbon sources proved that our strain has excellent performances in utilizing organic materials, which were verified by transcriptomic analysis. Finally, the strain was applied to treat four types of sugar-containing wastewaters. Among them, our strain exerts the best removal capability of COD (90%), nitrogen (89%), and phosphate (82%) for brewery wastewater.

Abstract

In the pursuit of novel approaches to address chronic heart failure and enhance cardiovascular nursing care, environmentally sustainable nanomaterials have taken center stage. Recent progress in regenerative medicine has opened doors for the use of biocompatible biomaterials that provide mechanical support to damaged heart tissue and facilitate electrical signaling. This study was dedicated to developing advanced electroconductive nanofibers by incorporating eco-friendly Avena sativa L. extract-mediated gold nanoparticles (AuNPs) into polyaniline to create an intricate cardiac patch. The AuNPs were synthesized through an environmentally friendly chemical process aided by ultrasonic conditions. Comprehensive physicochemical analyses, such as UV–Vis spectroscopy, SEM, TEM, DPPH assay, and XRD, were carried out to characterize the AuNPs. These AuNPs were then blended with a polycaprolactone/gelatin polymeric solution and electrospun to fabricate cardiac patches, which underwent thorough evaluation using various techniques. The resulting cardiac patch demonstrated excellent hemocompatibility, antioxidant properties, and cytocompatibility, offering a promising therapeutic approach for myocardial infarctions and the advancement of cardiovascular nursing care.

Abstract

This research investigated the biodegradation kinetics, pathways and ecological risk of hexabromocyclododecane (HBCD) by a novel bacterium Citrobacter sp. Y3. Results showed the biodegradation followed a first-order model. The specific degradation rate constant of HBCD were obviously higher in batch experiments with combined carbon sources (k: 0.156–0.290 d−1) than those using HBCD as the sole carbon source (k: 0.055 d−1). Correspondingly, the degradation half-life became much shorter (T1/2: 2.39–4.44 d vs T1/2: 13.7 d). HBCD could be degraded through dehydrobromination and dehalohydroxylation, of which six possible degradation products were detected. To evaluate the ecological risk of HBCD biodegradation products, acute toxicity tests were assessed for the first time. The acute toxicity decreased slowly during treatment for 3–5 d and then decreased sharply. In general, treatment by Strain Y3 is not only a biodegradation process but also a detoxification process, thus it shows potential for bioremediation of HBCD contaminated sites.

Abstract

Organo-montmorillonite supported zero-valent iron nanoparticles (Fe 0 /OMt) with well-dispersion and higher specific surface area were synthesized for the degradation of tetrabromobisphenol A (TBBPA) and bisphenol A (BPA) in aqueous solution. X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET), transmission electron microscopy (TEM), Energy-Dispersive X-ray elemental mapping, and X-ray photoelectron microscopy (XPS) were used to characterize the composition and microstructures of Fe 0 /OMt. Interestingly, nanoscale zero-valent iron (Fe 0 ) core with a uniform iron oxide shell are formed and well dispersed on the organo-montmorillonite supports. After systematical optimization of treatment conditions, Fe 0 /OMt (0.1 g/L) with sparging O 3 (concentration of 4 mg/L) demonstrated excellent degradation efficiency for TBBPA and BPA (98.6% and 94.7%, respectively) with the initial concentration of 10 mg/L. Notably, in the aforementioned oxic conditions, bromide ions, ferrous ion, and hydroxyl radicals were detected during the progressive degradation of the TBBPA and BPA, suggesting that TBBPA was debrominated as the primary step then completely mineralized by oxidative process. Finally, combined with the analysis of degradation products identified by LC–MS, pathways of TBBPA and BPA over Fe 0 /OMt were proposed. These results revealed that a Fe 0 /OMt based on advanced oxidation technology is of great potential for remediating TBBPA and BPA in aqueous environment.

Abstract

In this study, remediation of tetrabromobisphenol-A (TBBPA) from aqueous solution by sorption using transition metals-modified inorganic–organic montmorillonite (IOMt) was demonstrated. The adsorbents were prepared in two steps: (1) intercalation of surfactants into Al13-pillared montmorillonite for synthesizing two types of IOMt; (2) incorporation of transition metals (Cu2+, Ni2+, or Co2+) onto those IOMts. Firstly, these materials were characterized by XRD, FTIR, TGA, SEM-EDS, and BET analyses. Then, experiments were conducted on the sorption isotherms, kinetics, and thermodynamics of TBBPA. In general, sorption process with Cu- and Ni-modified IOMt achieved higher TBBPA removal efficiency than sorption process with original IOMt. The modified IOMt displayed the sorption capacity that varied depending on TBBPA initial concentration, pH, and metals loading. However, the type of surfactants did not influence TBBPA sorption on metals-modified IOMt. This probably indicated that complex interaction b...

Abstract

In this study, we took advantage of the conventionally used physical backwashing and chemical cleaning methods to develop an on-line maintenance cleaning method using the NaOH solution (0.01 mol/L, pH around 12) as the backwashing agent in a membrane bioreactor (MBR) operated at two imposed fluxes (6.5 and 13 L/(m 2 ·h) (LMH)). The results indicate that NaOH backwashing had little adverse effect on biological nutrient removal, and the pH in the MBR reactor remained at stable and acceptable levels (6.6–7.8) because of the alkali consumption by the nitrification process and the buffering role of the mixed liquor. Importantly, the NaOH backwashing significantly slowed the increased rates of total fouling (50% and 69% for 6.5 and 13 LMH, respectively) and irreversible fouling (40% and 50% for 6.5 and 13 LMH, respectively) compared with the pure water backwashing. Off-line backwashing tests indicate that NaOH backwashing enhanced the detachment of biopolymers from the surface of fouled membranes due to the co-occurrence of hydraulic actions and chemical alterations. The characterizations by scanning electron microscopy (SEM) indicate that both backwashing methods increased the size of membrane pores. Nevertheless, the Fourier transform-infrared spectrometry (FTIR) of membranes indicates that the long-term exposure to the NaOH solution did not change the chemical structure of membranes. This study suggests that on-line NaOH backwashing could not only maintain membrane permeability but also simultaneously supply alkali to bioreactors to ultimately facilitate the operation of MBRs.

Abstract

Abstract Main goal of the JUNO experiment is to determine the neutrino mass ordering using a 20 kt liquid-scintillator detector. Its key feature is an excellent energy resolution of at least 3% at 1 MeV, for which its instruments need to meet a certain quality and thus have to be fully characterized. More than 20,000 20-inch PMTs have been received and assessed by JUNO after a detailed testing program which began in 2017 and elapsed for about four years. Based on this mass characterization and a set of specific requirements, a good quality of all accepted PMTs could be ascertained. This paper presents the performed testing procedure with the designed testing systems as well as the statistical characteristics of all 20-inch PMTs intended to be used in the JUNO experiment, covering more than fifteen performance parameters including the photocathode uniformity. This constitutes the largest sample of 20-inch PMTs ever produced and studied in detail to date, i.e. 15,000 of the newly developed 20-inch MCP-PMTs from Northern Night Vision Technology Co. (NNVT) and 5000 of dynode PMTs from Hamamatsu Photonics K. K.(HPK).

Abstract

The physics potential of detecting ^8 B solar neutrinos will be exploited at the Jiangmen Underground Neutrino Observatory (JUNO), in a model-independent manner by using three distinct channels of the charged current (CC), neutral current (NC), and elastic scattering (ES) interactions. Due to the largest-ever mass of ^13 C nuclei in the liquid scintillator detectors and the expected low background level, ^8 B solar neutrinos are observable in the CC and NC interactions on ^13 C for the first time. By virtue of optimized event selections and muon veto strategies, backgrounds from the accidental coincidence, muon-induced isotopes, and external backgrounds can be greatly suppressed. Excellent signal-to-background ratios can be achieved in the CC, NC, and ES channels to guarantee the observation of the ^8 B solar neutrinos. From the sensitivity studies performed in this work, we show that JUNO, with 10 yr of data, can reach the 1 σ precision levels of 5%, 8%, and 20% for the ^8 B neutrino flux, ${\sin }^{2}{\theta }_{12}$ , and ${\rm{\Delta }}{m}_{21}^{2}$ , respectively. Probing the details of both solar physics and neutrino physics would be unique and helpful. In addition, when combined with the Sudbury Neutrino Observatory measurement, the world's best precision of 3% is expected for the measurement of the ^8 B neutrino flux.

Abstract

The objective of this study was to highlight the significance of microorganism growth on the production of biomacromolecules (BMM) in a membrane bioreactor (MBR). During the MBR operation, both polysaccharides and proteins in the sludge supernatant were found to increase steadily in exponential growth phase (EGP) due to higher organic loading rates and microbial primary metabolism. Subsequently, both increased continuously and then decreased sharply in the following deceleration growth phase (DGP). Finally, the BMM maintained a low and steady level as the sludge reached stationary growth phase (SGP). The results of batch experiments showed that the sludge under DGP was prone to produce much more BMM than that under SGP as a result of a nutrients decrease and higher microbial secondary metabolism activities. Furthermore, large-molecular weight (MW) compounds (>100 kDa) made up the majority of BMM in the EGP and DGP. In contrast, the small-MW compounds (

Abstract

To evaluate the effects of operating nuclear power plants on the ecological environment in the surrounding sea areas, 4 nuclear power plants which had been operated along the coast of China, namely Tianwan Nuclear Power Plant, Qinshan Nuclear Power Plant, Ningde Nuclear Power Plant and Fuqing Nuclear Power Plant, were selected as research objects. The specific activity of main radionuclides in fish and surface sediments in the surrounding sea areas was determined from June to September of 2016 and from April to July of 2017 respectively, and the sources of surface sediments were analyzed. The results showed that the operation of nuclear power plant had not affected the radioactivity level of fish and surface sediments in surrounding sea areas, and the specific activity of 137Cs and 226Ra in fish was much lower than the detection limits of national food. Specific activity of 238U, 226Ra and 228Ra in surface sediments increased gradually with the decrease of latitude, and that of 137Cs decreased with time compared with the results of earlier literature. According to the average 226Ra/238U value of surface sediments, the sources of surface sediments in different areas were different, and the higher the correlation between 226Ra and 228Ra specific activity, the more single the source of surface sediments.

Abstract

Abstract We study damping signatures at the Jiangmen Underground Neutrino Observatory (JUNO), a medium-baseline reactor neutrino oscillation experiment. These damping signatures are motivated by various new physics models, including quantum decoherence, ν 3 decay, neutrino absorption, and wave packet decoherence. The phenomenological effects of these models can be characterized by exponential damping factors at the probability level. We assess how well JUNO can constrain these damping parameters and how to disentangle these different damping signatures at JUNO. Compared to current experimental limits, JUNO can significantly improve the limits on τ 3/m 3 in the ν 3 decay model, the width of the neutrino wave packet σ x , and the intrinsic relative dispersion of neutrino momentum σ rel.

Abstract

Abstract The OSIRIS detector is a subsystem of the liquid scintillator filling chain of the JUNO reactor neutrino experiment. Its purpose is to validate the radiopurity of the scintillator to assure that all components of the JUNO scintillator system work to specifications and only neutrino-grade scintillator is filled into the JUNO Central Detector. The aspired sensitivity level of $$10^{-16}\hbox { g/g}$$ 10 - 16 g/g of $$^{238}\hbox {U}$$ 238 U and $$^{232}\hbox {Th}$$ 232 Th requires a large ( $$\sim 20\,\hbox {m}^3$$ ∼ 20 m 3 ) detection volume and ultralow background levels. The present paper reports on the design and major components of the OSIRIS detector, the detector simulation as well as the measuring strategies foreseen and the sensitivity levels to U/Th that can be reached in this setup.

Abstract

Abstract JUNO is a massive liquid scintillator detector with a primary scientific goal of determining the neutrino mass ordering by studying the oscillated anti-neutrino flux coming from two nuclear power plants at 53 km distance. The expected signal anti-neutrino interaction rate is only 60 counts per day (cpd), therefore a careful control of the background sources due to radioactivity is critical. In particular, natural radioactivity present in all materials and in the environment represents a serious issue that could impair the sensitivity of the experiment if appropriate countermeasures were not foreseen. In this paper we discuss the background reduction strategies undertaken by the JUNO collaboration to reduce at minimum the impact of natural radioactivity. We describe our efforts for an optimized experimental design, a careful material screening and accurate detector production handling, and a constant control of the expected results through a meticulous Monte Carlo simulation program. We show that all these actions should allow us to keep the background count rate safely below the target value of 10 Hz (i.e. ∼1 cpd accidental background) in the default fiducial volume, above an energy threshold of 0.7 MeV.

Abstract

Abstract Atmospheric neutrinos are one of the most relevant natural neutrino sources that can be exploited to infer properties about cosmic rays and neutrino oscillations. The Jiangmen Underground Neutrino Observatory (JUNO) experiment, a 20 kton liquid scintillator detector with excellent energy resolution is currently under construction in China. JUNO will be able to detect several atmospheric neutrinos per day given the large volume. A study on the JUNO detection and reconstruction capabilities of atmospheric $$\nu _e$$ ν e and $$\nu _\mu $$ ν μ fluxes is presented in this paper. In this study, a sample of atmospheric neutrino Monte Carlo events has been generated, starting from theoretical models, and then processed by the detector simulation. The excellent timing resolution of the 3” PMT light detection system of JUNO detector and the much higher light yield for scintillation over Cherenkov allow to measure the time structure of the scintillation light with very high precision. Since $$\nu _e$$ ν e and $$\nu _\mu $$ ν μ interactions produce a slightly different light pattern, the different time evolution of light allows to discriminate the flavor of primary neutrinos. A probabilistic unfolding method has been used, in order to infer the primary neutrino energy spectrum from the detector experimental observables. The simulated spectrum has been reconstructed between 100 MeV and 10 GeV, showing a great potential of the detector in the atmospheric low energy region.

Abstract

Ecological corridors (ECs) are important management tools to protect biodiversity by linking fragile habitats, especially for highly mobile organisms. ECs in terrestrial landscapes work as passages on land or in water. However, the significance of ECs to migratory species in estuaries has not been well elucidated. Based on annual fishery investigation in the Yangtze estuary and their dominance index rank, three of the top five species, including Larimochthys polyactis, Coilia mystus, and Gobiidae, exhibited absolute dominance in spring during the past 5 years. The temporal and spatial density variance of C. mystus supported its short-distance migration pattern. Redundancy analysis and the MaxEnt model predicted optimum habitats for C. mystus. C. mystus larvae survival was significantly related to salinity, total nitrogen, pH, reactive silicate, dissolved oxygen, surface water temperature, and chlorophyll-a in May and to salinity, surface water temperature, permanganate index, suspended particles, total nitrogen, and total phosphorus in August. The MaxEnt model predicted a broader longitudinal distribution range from offshore to the upstream freshwater area but narrower latitudinal distribution in the southern branch in May than in August. Finally, we delineated migratory corridors connecting optimum habitats for C. mystus using the least-cost route method. Optimum habitats close to the coastlines in the south branch might play a significant role in maintaining population or community connectivity in the Yangtze estuary. Our findings provide a perspective and method to quantify and facilitate the harmonious development of socioeconomy and fishery biodiversity conservation.

Abstract

The acceleration of the composting process and the improvement of compost quality have been explored by evaluating the efficacy of various additives, inoculating with specific microorganisms and the application of various biosurfactants. The magnesium-aluminum silicate attapulgite is a low-cost potential composting additive, but its effects on aerobic composting are unknown. This study investigated the effects of attapulgite application on compost production and quality during the aerobic composting of chicken manure. Addition of attapulgite significantly increased the temperature (p0.05) while it reduced compost total organic carbon (TOC) and seed germination indices (GIs) throughout the process. Its addition enhanced nitrate concentrations, promoted organic matter degradation, increased seed germination indices, and accelerated the composting process. Interestingly, attapulgite addition did not increase the population of ammonia-oxidizing bacteria. These results suggest that attapulgite is a good additive for the composting industry.We investigated the addition of two forms of attapulgite during aerobic composting of chicken manure to determine their effects under strict composting environmental parameter control. Our results provides primary evidence that attapulgite may have potential for application in the composting industry. All treatments showed no increase within the first 15 days. However, emissions increased for all treatments within 15-45 days, reaching approximately 6300, 2000, and 4000 mg/m2 from the control, artifactitious attapulgite, and raw attapulgite treatments, respectively.

Abstract

Background The complex characteristics and unclear biological fate of biomacromolecules (BMM), including colloidal and soluble microbial products (SMP), extracellular polymeric substances (EPS) and membrane surface foulants (MSF), are crucial factors that limit our understanding of membrane fouling in membrane bioreactors (MBRs). Findings In this study, the microbial transformation of BMM was investigated in a lab-scale MBR by well-controlled bioassay tests. The results of experimental measurements and mathematical modeling show that SMP, EPS, and MSF had different biodegradation behaviors and kinetic models. Based on the multi-exponential G models, SMP were mainly composed of slowly biodegradable polysaccharides (PS), proteins (PN), and non-biodegradable humic substances (HS). In contrast, EPS contained a large number of readily biodegradable PN, slowly biodegradable PS and HS. MSF were dominated by slowly biodegradable PS, which had a degradation rate constant similar to that of SMP-PS, while degradation behaviors of MSF-PN and MSF-HS were much more similar to those of EPS-PN and EPS-HS, respectively. In addition, the large-molecular weight (MW) compounds (>100 kDa) in BMM were found to have a faster microbial transformation rate compared to the small-MW compounds (

Abstract

Abstract We present the calibration strategy for the 20 kton liquid scintillator central detector of the Jiangmen Underground Neutrino Observatory (JUNO). By utilizing a comprehensive multiple-source and multiple-positional calibration program, in combination with a novel dual calorimetry technique exploiting two independent photosensors and readout systems, we demonstrate that the JUNO central detector can achieve a better than 1% energy linearity and a 3% effective energy resolution, required by the neutrino mass ordering determination.

Abstract

The photocatalytic process of TiO2/H2O2/UV, first, was applied to degrade tetrabromobisphenol A (TBBPA) in aqueous system. Under the optimal conditions, the degrading efficiency of TBBPA reached 99.3% after 150 min when 120 W UV (0.42 mW/cm2), 3% H2O2, and 400 mg/L of 500°C-calcined TiO2. During the photocatalytic degradation process, hydroxyl radicals (·OH) were considered to be the main reactive oxidative species involved in attacking TBBPA, and bromide ions generation with the conducting reaction. Moreover, five intermediates were detected by liquid chromatography–mass spectrometry, and a photocatalytic degradation pathway was proposed. The combination with excellent efficiency for TBBPA provided a potential technology for the treatment of TBBPA-contaminated wastewater or environments. [ABSTRACT FROM AUTHOR]

Abstract

This work was to examine adsorption of tetrabromobisphenol-A onto acidic montmorillonite (K10) which had been considered as a potential adsorbent for removal of organic pollutants. The Langmuir, Freundlich, Langmuir–Freundlich, and Dubinin–Radushkevich models were applied with determination of sorption and desorption equilibrium isotherms and isotherms constants. The discrimination had been performed by means of various statistics. The results showed that Freundlich and Langmuir–Freundlich models described the sorption isotherms better than Langmuir model. Meanwhile, desorption hysteresis index calculated from Freundlich model was above zero and increased with increasing temperature, indicating occurrence of hysteresis. Preliminary to the isotherms data, adsorption kinetic had been gathered and tested using pseudo-first-order, pseudo-second-order, intra-particle diffusion, and double-exponential models (DEMs). From the kinetic studies, sorption process was completed in 48 h, and followed pseudo-second-order model and DEMs. Cationic surfactant in aqueous solution had positive effect on adsorption process, and the metal cations promoted sorption capacity in the order: Ni2+ > K+ > Zn2+ > Ca2+ > Na+. The optimum adsorption capacity was provided by the condition of pH 3, T = 288 K, and I = Ni2+. Additionally, the thermodynamic parameters indicated the sorption was exothermic and spontaneous. The interaction between K10 and TBBPA was investigated using FTIR. [ABSTRACT FROM AUTHOR]
