However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol(1,6-HDO) with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments(LCAs).Strategy A was found to be the most favorable both economically(USRDSCHARDOLLAR3,402/ton) and environmentally(-26.9 kg CO_(2)eq.). This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.展开更多

文摘Background There is a growing focus on using various plant-derived agricultural by-products to increase the benefits of pig farming,but these feedstuffs are fibrous in nature.This study investigated the relationship between dietary fiber physicochemical properties and feedstuff fermentation characteristics and their effects on nutrient utilization,energy metabolism,and gut microbiota in growing pigs.Methods Thirty-six growing barrows(47.2±1.5 kg)were randomly allotted to 6 dietary treatments with 2 apparent viscosity levels and 3β-glucan-to-arabinoxylan ratios.In the experiment,nutrient utilization,energy metabolism,fecal microbial community,and production and absorption of short-chain fatty acid(SCFA)of pigs were investigated.In vitro digestion and fermentation models were used to compare the fermentation characteristics of feedstuffs and ileal digesta in the pig’s hindgut.Results The production dynamics of SCFA and dry matter corrected gas production of different feedstuffs during in vitro fermentation were different and closely related to the physical properties and chemical structure of the fiber.In animal experiments,increasing the dietary apparent viscosity and theβ-glucan-to-arabinoxylan ratios both increased the apparent ileal digestibility(AID),apparent total tract digestibility(ATTD),and hindgut digestibility of fiber components while decreasing the AID and ATTD of dry matter and organic matter(P<0.05).In addition,increasing dietary apparent viscosity andβ-glucan-to-arabinoxylan ratios both increased gas exchange,heat production,and protein oxidation,and decreased energy deposition(P<0.05).The dietary apparent viscosity andβ-glucanto-arabinoxylan ratios had linear interaction effects on the digestible energy,metabolizable energy,retained energy(RE),and net energy(NE)of the diets(P<0.05).At the same time,the increase of dietary apparent viscosity andβ-glucan-to-arabinoxylan ratios both increased SCFA production and absorption(P<0.05).Increasing the dietary apparent viscosity andβ-glucan-to-arabinoxylan ratios increased the diversity and abundance of bacteria(P<0.05)and the relative abundance of beneficial bacteria.Furthermore,increasing the dietaryβ-glucan-to-arabinoxylan ratios led to a linear increase in SCFA production during the in vitro fermentation of ileal digesta(P<0.001).Finally,the prediction equations for RE and NE were established.Conclusion Dietary fiber physicochemical properties alter dietary fermentation patterns and regulate nutrient utilization,energy metabolism,and pig gut microbiota composition and metabolites.

文摘Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol(1,6-HDO) with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments(LCAs).Strategy A was found to be the most favorable both economically(USRDSCHARDOLLAR3,402/ton) and environmentally(-26.9 kg CO_(2)eq.). This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.

文摘Tantalum nitride is widely considered as a promising photoanode material for its suitable band structure as well as the high theoretical conversion efficiency in solar water splitting.However,it is limited to inefficient photoinduced electron–hole pair separation and interfacial dynamics in the photoelectrochemical oxygen evolution reaction.Herein,multiple layers including Ti_(x)Si_(y) and NiFeCoO_(x) were fabricated based on band engineering to regulate tandem electric states for efficient transfer of energy carriers.Besides,photothermal local surface plasmon resonance was introduced to accelerate the kinetics of photoelectrochemical reactions at the interface when the special Ag nanoparticles were loaded to extend the absorbance to near infrared light.Consequently,a recordable photocurrent density of 12.73 mA cm^(-2) has been achieved at 1.23 V versus RHE,approaching a theoretical limit of the tantalum nitride photoanode with full-spectrum solar utilization.Meanwhile,compared to the applied bias photon-to-current efficiency of 1.36%without photothermal factor,a high applied bias photonto-current efficiency of 2.27%could be raised by applying local surface plasmon resonance to photoelectrochemical oxygen evolution reaction.The efficient design could maximize the use of solar light via the classification of spectrum and,therefore,may spark more innovative ideas for the future design and development of the next-generation photoelectrode.
文摘BACKGROUND There is increasing incidence of alcohol-associated liver disease in females.Despite this recent increased incidence,there is a paucity of research on the clinical course and outcomes of alcohol-associated hepatitis(AH)in females compared to males.AIM To assess if there may be sex differences in severity,outcomes,and healthcare utilization for patients hospitalized for AH.METHODS This study used ICD-9-CM and ICD-10-CM codes to retrospectively identify inpatient encounters for AH at the University of Kentucky from 2012-2021 and obtained data on patient demographics and clinical outcomes.Encounters were cohorted by patient sex and differences in patient demographics and clinical outcomes were assessed.Multivariate logistic regression models were constructed to assess risk of mortality,sepsis,and mechanical ventilation during the encounter.RESULTS Of 1386 subjects,511(36.9%)were female and 875(63.1%)were male.Both sexes had similar baseline characteristics of race/ethnicity,discriminant function score,model of end-stage liver disease score,and length of hospital stay.However,the incidence of urinary tract infection,sepsis,and norepinephrine administration was significantly higher for females.Males had a significantly higher incidence of esophageal variceal bleed.On multivariate logistic regression analysis,females had higher odds of encounter sepsis(OR 1.41;95%CI:1.064-1.869)and mechanical ventilation(OR 1.352;95%CI:1.006-1.816).Odds of encounter mortality were significantly increased in encounters with sepsis(OR 2.309;95%CI:1.419-3.757)and mechanical ventilation(OR 9.301;95%CI:5.724-15.114).CONCLUSION This study shows sex-based differences in AH outcomes at the University of Kentucky.Future studies are warranted to assess whether tailoring treatments will improve clinical outcomes in females with AH.

文摘The effects of micro-ridge-furrow planting(MR)on yield and the efficiency of light,water,and thermal resource use in rapeseed were tested in a three-year field experiment comparing MR to conventional flat planting.MR enhanced canopy heterogeneity by altering the leaf angle between plants on ridges and furrows.The heterogeneous canopy environment increased intercepted photosynthetic active radiation,alleviated canopy temperature stress,and optimized canopy humidity,leading to improvements in light-nitrogen matching and net photosynthetic rate.Consequently,dry matter and yield increased by 13.0%and 11.0%,respectively,while radiation,thermal,and precipitation utilization efficiency increased by 12.3%-16.2%.The corresponding improvements in yield and resource use efficiency were attributed to a heterogeneous canopy environment that improved microclimatic conditions.

文摘BACKGROUND Adolescence is a period marked by physiological and psychological imbalances,which pose an increased risk for adolescents with major depressive disorder(MDD)to commit non-suicidal self-injury(NSSI).AIM To investigate the moderating role of social support utilization in depression and NSSI among adolescents with MDD.METHODS This cross-sectional study enrolled 314 adolescents with MDD(258 with NSSI,56 without)from a Chinese tertiary psychiatric hospital(2021-2023).Participants completed validated scales,including the self-esteem scale,the Barratt impulsiveness scale,the self-rating depression scale,and the teenager social support rating scale.Logistic regression and hierarchical regression analyses were used to examine predictors of NSSI and the moderating effect of social support utilization.RESULTS Results showed that the NSSI group had higher depression levels,lower selfesteem,and greater impulsivity.While overall social support was higher in the NSSI group,social support utilization significantly moderated the depression-NSSI relationship.Specifically,higher utilization levels weakened the association between depression and NSSI(β=-0.001,P<0.05).CONCLUSION These findings suggest that effective utilization of social support,rather than its mere presence,is crucial in reducing NSSI risk among depressed adolescents.

文摘One-time application of controlled-release blended fertilizer(CRBF,a mixture of five nitrogen(N)fertilizers in a certain ratio)can achieve high yield and N use efficiency(NUE)in rice(Oryza sativa L.).However,the effects of CRBF with one-time application on root spatial distribution and physiological characteristics remain unclear.We measured the effects of CRBF with one-time application on rice yield,NUE,root morphology and growth,and N uptake capacity in field and root box experiments.Six N treatments were set up:no nitrogen(N0),high-yield three-split application of urea as a control(CK),urea(U)with broadcast,U with side-deep fertilization,CRBF with broadcast,and CRBF with side-deep fertilization.Our findings showed that root characters were positively correlated with yield and NUE.Compared to CK and U treatments,CRBF with one-time applications increased root characters(including root biomass,root N uptake,root activity,and the expression level of ammonium transporters)at tillering and heading stages.The root length,surface area and volume in the 0-10 cm soil layer enhanced under CRBF with one-time applications at tillering stage,and in the 0-20 cm soil layer at the heading stage.This contributed a5.96%-39.40% and 3.69%-16.87% increase in plant dry matter accumulation and N uptake,and a2.08%-18.28% and 14.60%-149.57% increase in yield and NUE,in 2022 and 2023,respectively.Taken together,our findings showed that one-time application of CRBF could increase rice yield and NUE by optimizing the root morphology distribution and N uptake.
