Markov processes provide a popular approach to construct low-dimensional dynamical models of a complex biomolecular system. By partitioning the conformational space into metastable states, protein dynamics can be approximated in terms of memory-less jumps between these states, resulting in a Markov state model (MSM). Alternatively, suitable low-dimensional collective variables may be identified to construct a data-driven Langevin equation (dLE). In both cases, the underlying Markovian approximation requires a propagation time step (or lag time) delta t that is longer than the memory time tau (M) of the system. On the other hand, delta t needs to be chosen short enough to resolve the system timescale tau (S) of interest. If these conditions are in conflict (i.e., tau (M) > tau (S)), one may opt for a short time step delta t = tau (S) and try to account for the residual non-Markovianity of the data by optimizing the transition matrix or the Langevin fields such that the resulting model best reproduces the observables of interest. In this work, rescaling the friction tensor of the dLE based on short-time information in order to obtain the correct long-time behavior of the system is suggested. Adopting various model problems of increasing complexity, including a double-well system, the dissociation of solvated sodium chloride, and the functional dynamics of T4 lysozyme, the virtues and shortcomings of the rescaled dLE are discussed and compared to the corresponding MSMs.

This study investigates the use of chloride-free calcium-based chemical accelerators in ordinary concrete incorporating freshly homogenized electric arc-furnace dust (EAFD). The utilization of calcium nitrite (CN) and calcium formate (CF) counteracts the negative impact of elevated zinc oxide content in fresh EAFD. The presence of ZnO dramatically delays the setting time of cement in paste and concrete. In this study, EAFD was used in different replacement levels varied from 0 to 12% of cement. The incorporation of EAFD in concrete increased the setting time of concrete by up to 68 h. However, the presence of chemical accelerators enabled a significant reduction in setting time. The hydration reaction formed around cement grains due to the reaction between ZnO in EAFD and portlandite (Ca(OH)(2)) is responsible for the delay in setting time. This delay could be overcome under the influence of a concentration gradient due to the effective chemical accelerator dosage. The use of EAFD in concrete showed similar strength to silica fume (SF) mixes. The efficiencies of CN and CF rely on their dosage and EAFD content. It is concluded that the effective chemical accelerator-to-EAFD ratio plays a vital role in mitigating the extensive delay in setting time to practically feasible values. The mixture containing 4% CN and 4% EAFD was identified as the best concrete mixture. (C) 2020 Elsevier Ltd. All rights reserved.

Uranium(VI) toxicity in tobacco BY-2 cell suspension culture – A physiological study

For the first time, the physiological and cellular responses of Nicotiana tabacum (BY-2) cells to uranium (U) as an abiotic stressor were studied using a multi-analytic approach that combined biochemical analysis, thermodynamic modeling and spectroscopic studies. The goal of this investigation was to determine the U threshold toxicity in tobacco BY-2 cells, the influence of U on the homeostasis of micro-macro essential nutrients, as well as the effect of Fe starvation on U bioassociation in cultured BY-2 cells. Our findings demonstrated that U interferes with the homeostasis of essential elements. The interaction of U with BY-2 cells confirmed both timeand concentration-dependent kinetics. Under Fe deficiency, a reduced level of U was detected in the cells compared to Fe-sufficient conditions. Interestingly, blocking the Ca channels with gadolinium chloride caused a decrease in U concentration in the BY-2 cells. Spectroscopic studies evidenced changes in the U speciation in the culture media with increasing exposure time under both Fe-sufficient and deficient conditions, leading us to conclude that different stress response reactions are related to Fe metabolism. Moreover, it is suggested that U toxicity in BY-2 cells is highly dependent on the existence of other micro-macro elements as shown by negative synergistic effects of U and Fe on cell viability.

Bio-improved hydraulic properties of sand treated by soybean urease induced carbonate precipitation and its application Part 2: Sand-geotextile capillary barrier effect

Nonwoven-geotextile is used to construct soil-geotextile capillary barrier for minimizing water infiltration. However, the sand-geotextile capillary barrier breakthrough can occur due to the low water retention ability and the high saturated permeability coefficient of sand. To address this, enzyme induced carbonate precipitation (EICP) technology was applied to the overlying sand layer to improve its hydraulic properties and enhance the sand-geotextile capillary barrier. The precipitated calcium carbonate has the potential to enhance the capillary barrier effect by coating soil particles and filling the soil macro-pores. To investigate the effect of EICP treatment on the sand-geotextile capillary barrier, three column tests were conducted, including one untreated sand-geotextile column and two sand-geotextile columns treated with 0.5 and 1 mol/L urea-calcium chloride solutions and soybean urease liquid, respectively. Transient seepage analysis was carried out based on the column tests to calibrate the hydraulic parameters. A numerical parametric analysis was conducted to assess the effect of EICP-enhancement on the hydraulic behavior and slope stability of a sand-geotextile capillary barrier retaining wall during exposure to rainfall with a 100-year return period. The results of the column infiltration tests show that the occurrence of breakthrough in the sand-geotextile capillary barrier is significantly delayed with increasing concentration of the urea-calcium chloride solutions. The enhanced capillary barrier effect is attributed to the increased water retention ability and reduced saturated permeability coefficient. The results of the parametric analysis show that the matric suction within the backfill is maintained and the factor of safety remains almost unchanged due to the EICP-enhanced sand-geotextile capillary barrier effect.

Applications of UV/H2O2, UV/persulfate, and UV/persulfate/Cu2+ for the elimination of reverse osmosis concentrate generated from municipal wastewater reclamation treatment plant: Toxicity, transformation products, and disinfection byproducts

Reverse osmosis concentrate (ROC) resulting from treatment of municipal wastewater reclamation involves high concentrations of recalcitrant pollutants. This study evaluated the toxicity of an ROC containing harmful biocides during representative UV synergistic oxidation processes (SOPs) (e.g., UV/hydrogen peroxide (H2O2), UV/persulfate (PS), and UV/PS/Cu2+). Treated ROC exhibited up to 1.3-2.3 times higher toxicity than the parent compounds such as dodecyl trimethyl ammonium chloride (DTAC) and dodecyl dimethyl benzyl ammonium chloride (DDBAC). Based on the intermediates identification, the major toxic intermediates were screened through silico assessment using the quantitative Ecological Structure-Activity Relationship (ECOSAR) tool. The transformation products (TPs) of hydroxylation and ketonization were the major formed reactions from the UV/PS/Cu2+. Also, some cytotoxic TPs were accumulated during the UV/H2O2 and UV/PS oxidations, where the carbonaceous-disinfection byproducts were more than the nitrogenous-disinfection byproducts. In the presence of chloride and bromide, chlorate and bromate could be formed during the UV-SOP; they were influenced by the different water matrix in comparison with the different ROC. Also, the formation of the total organic halogen species (TOX) was found to follow this order: UV/PS/Cu2+< UV/H2O2 < UV/PS. In this study, the predicted cytotoxicity using the correlation between the TOX and the cytotoxicity was more acceptable than that of the cytotoxicity index method. Further, the R-square of the correlation between the TOX and the cytotoxicity for the UV/H2O2 and UV/PS was 0.82 and 0.79, respectively. The predicted cytotoxicity using the TOX correlation method in the ROC could also be used to monitor and prevent the application of different oxidations inmunicipal wastewater reclamation treatment plants.

Synthesis of N-(3-aminopropyl)imidazole-based poly(ionic liquid) as an adsorbent for the selective recovery of Au(iii) ions from aqueous solutions

The synthesis of a novel poly(ionic liquid) adsorbent (PIL-APIBCl) through the modification of poly(styrene-co-maleic anhydride) (PSMA) composites with N-(3-aminopropyl)imidazole (API) and benzyl chloride (BCl) is presented. The structural analysis was carried out by nuclear magnetic resonance (NMR), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM) and Fourier transform infrared (FT-IR). Batch adsorption experiments revealed that the investigated adsorbent exhibited good selectivity and a high adsorption capacity of 236.68 mg g(-1) towards tetrachloroaurate (Au(iii)) ions at pH 1.0 over a wide temperature range. The adsorption isotherms and kinetics of Au(iii) on the PIL-APIBCl were fitted well by the Langmuir isotherm model and pseudo-second-order model, respectively, indicating successful chemical adsorption of Au(iii) ions on the adsorbent surfaces. According to FESEM, FT-IR, XPS and NMR analysis, the adsorption mechanisms of Au(iii) on PIL-APIBCl could be ascribed to electrostatic and intermolecular interactions. Therefore, due to its good cyclability and low cost, PIL-APIBCl is a promising adsorbent for Au(iii) recovery from wastewater on a large scale.

Synthesis and Structural Characterization of Pyridine-based Mn(III), Fe(III), and Co(III) Complexes as SOD Mimics and BSA Binding Studies

Interaction of 2-picolylamine (2-PA) with Mn(II), Fe(III) and Co(II) chlorides in an ethanolic solution yields two types of metal chelates. The analytical data, thermal analysis (TGA and DTG), molar conductance, electrochemical, magnetic studies and spectral (IR, UV-Vis, NMR and ESR) results supported the binuclear bridging mu-peroxo formulation of the brown (Mn-III) and yellow (Co-III) products such as [(ML2Cl)(2)(O-2)]Cl-2. Hexacoordinated distorted octahedral structure is proven for the mononuclear iron(III) complex [FeL2Cl2]Cl. PXRD data along with Expo 2014’s structural solution software were used for structure determination of the current metal chelates. The structural analysis results reveal that the bis-coordination system of the two bidentate N-2 donor ligands in a trans-fashion provides a square planer set of nitrogens and access for axial donors above and below the equatorial plane in the octahedron stereochemistry. Ligand substitution studies were conducted in order to correlate the lability character and the catalytic activities of the present metal chelates as SOD-mimics. The SOD mimetic catalytic activity was evaluated by both IC50 and the rate constant k(c) for the catalytic dismutation of O-2(-) . Electrochemical data were used to determine the driving force (Delta G degrees) for the catalytic disproportionation reactions of O-2(-) . Thermodynamics, kinetic and catalytic considerations of the catalytic scavenging reactions of O-2(-) were discussed. Absorption and fluorescence spectroscopy techniques were used in addition to fluorescence lifetime measurements to study the interaction between [FeL2Cl2]Cl and bovine serum albumin (BSA). The apparent binding constant, number of the binding sites and the fluorescence quenching mechanism were determined. (C) 2020 Elsevier B.V. All rights reserved.

A review of data for quantifying human exposures to micro and nanoplastics and potential health risks

Plastic debris have been shown to degenerate to particle sizes that can be transported in air, water, and food. Small particles are documented to enter and exit our bodies and translocate to and from some internal organs. Health effects on respiratory, hepatic, immune, and gastrointestinal systems have been reported in humans and other mammals in response to elevated particle or fiber exposures. These health effects differed by plastic type and size, and there was evidence of dose response for a few health endpoints. We conducted a systematic word search and reviewed published literature to identify microplastic and nanoplastic studies that quantified exposure via the ingestion, inhalation, and subcutaneous absorption (not dermal) exposure pathways; identified translocation, internal dose, and associations with health effects and markers related to exposures to specific sizes and types of plastics. We identified the data gaps in relating exposure data to health effects and biomarkers, most notably the lack of characterization of plastic particles and fibers smaller than 10 mu m in most media.

Investigation of choline chloride-formic acid pretreatment and Tween 80 to enhance sugarcane bagasse enzymatic hydrolysis

In this study, a pretreatment that consisting of choline chloride (ChCl) and formic acid (FA) were performed to improve sugarcane bagasse (SCB) enzymatic hydrolysis. Results showed that the ChCl-FA pretreatment exhibited an extraordinary ability to selectively extract hemicellulose (similar to 95.6%) and degrade a large number of lignin (similar to 72.6%) at 110 degrees C for 120 min, which enhanced the enzymatic hydrolysis of pretreated SCB. Besides, the impact of various additives on pretreated substrate enzymatic hydrolysis confirmed that Tween 80 was the best enzymatic additive, which could significantly improve the glucose produced from pretreated SCB and remarkably reduce the hydrolysis time (from 72 h to 48 h) and enzyme dosage (from 20 FPU/g pretreated solid to 10 FPU/g pretreated solid). In summary, the coupling of ChCl-FA pretreatment and Tween 80 exhibited a promising way to enhance the sugar release from SCB.

Ammonium sulfate production from wastewater and low-grade sulfuric acid using bipolar- and cation-exchange membranes

Conventional electrodialysis can be used to recover ammonia from dewatering centrate (i.e., downstream wastewater from digested sludge dewatering). However, ionic impurities of the recovered ammonia solution are still a limiting factor for broad applications of ion-exchange membranes (IEMs) in wastewater treatment and resource recovery. In this study, an electrodialysis stack with bipolar membranes (BPMs) and cation exchange membranes (CEMs) but without anion exchange membranes (AEMs) was examined under various operation conditions to demonstrate high-purity ammonium sulfate production using low-grade sulfuric acid and dewatering centrate. Two significant benefits of removing AEMs from the bipolar membrane electrodialysis (BMED) are no more membrane fouling problems on AEMs and complete exclusion of impurity anions (e.g., chloride ions) in the recovered ammonium sulfate solution. A higher applied voltage condition (30 V over 7 pairs of CEM and BPM) resulted in a substantially high ammonia recovery (88.4%) and concentration (4.34 g-N/L) in 90 min. The ammonia recovery and concentration were also improved by increasing the flow rate through the BMED stack. The lowest electric energy consumption in the membrane stack was 9.6 kW h/kg-N, indicating energy efficient production of high-purity ammonium sulfate from wastewater. The amount of divalent cation scales accumulated in the BMED stack was linearly proportional to the average electric current, implying that the scaling problem can be controlled by reducing the applied voltage. Even with the scale accumulation, the electric current generation (i.e., separation performance) was hardly affected during the experiment. These findings demonstrated the strong potential of AEM-lacking BMED for practical ammonia separation from wastewater with reduced impurities. (C) 2020 Elsevier Ltd. All rights reserved.
