Although,dietary proteins play a crucial role in poultry profit maximization,through the sustenance of birds`welfare,growth and development,yet metabolic excesses from crude protein(CP)degradation is detrimental to broiler chickens(BC)affected by heat stress.This study evaluated the effect of dietary protein levels on blood profile of heat-stressed BC at starter phase(SP)and finisher phase(FP).Arbor Acre BC(n=288)were randomly allotted to four dietary treatments(T1-23%CP;T2-21%CP;T3-19%CP;and T4-17%CP)with six replicate groups in a completely randomized design.Data were subjected to descriptive analysis,analysis of variance(p=0.05)and correlation statistics.Protein intake(PI)was not significantly affected by varying CP in diets at SP,but not at FP,where PI significantly increased with increasing dietary CP.PER had a negative correlation with PCV(r=-0.89,p<0.01),Hb(r=-0.88,p<0.01),RBC(r=-0.93,p<0.01)and PI(r=-0.78,p<0.01).Metabolic excesses including heat dissipation from dietary proteins influenced PCV,Hb,platelets and glucose of heat-stressed broilers. 展开更多

Press has been found to have an impact on the outcome of electoral political campaigns. Press can distort the electorate's perception of an objective reality to fulfill the political orientation of its editorial line. This can be achieved in propaganda and in the rhetoric of excess. Within the framework of Critical Discourse Analysis (CDA), this paper has conducted a thematic content analysis to study the rhetoric of excess in the construction of political identity and relations in 100 articles pertaining to two different ideologically oriented Tunisian newspapers, namely Le Maghreb and El Dhamir. The study covered the period from December 26, 2011 to December 26, 2012. Results have shown a low level of impartiality violating Gricean maxims of quality and quantity. This tendency could culminate in violence and undermine the public's confidence in the media. Proactive measures of media management are recommended. 展开更多

We perform a detailed study of scalar dark matter with triplet Higgs extensions of the Standard Model in order to explain the cosmic ray electron and positron excesses reported by AMS-02 and DAMPE.A detailed analysis of the AMS-02 positron excess reveals that for different orderings(normal,inverted,and quasi-degenerate)of neutrino mass,the hybrid triplet Higgs portal framework is more favored with respect to the single triplet Higgs portal for TeV scale dark matter.We also show that the resonant peak and continuous excess in DAMPE cosmic ray data can be well explained with the hybrid triplet Higgs portal dark matter when a dark matter sub-halo nearby is taken into account. 展开更多

Mass wasting is globally recognized as a key geomorphic agent in permanent gully expansion and greatly contributes to watershed sediment losses.Though its formation process has been assessed by some physical models,the occurrence and rainfall threshold have been rarely documented.In this study,rainfall-induced mass wasting events in two permanent gullies located in the Mollisols region of Northeast China,with Mollisols(gully 1)and sandy soil(gully 2)underneath were observed,and their differences were explored based on their soil strengths,hydraulic properties,excess topographies,and theoretical rainfall amounts.The sandy soil had a higher strength,faster pore water pressure dissipation rate,and lower suction stress at a specific soil moisture content compared to the black soil.The erosion thickness of the gully bed and sidewalls in gully 1 was shallower compared to gully 2.This was confirmed by the relationship between the erosion thickness and excess topography.The differences in the mass wasting erosion of the gully bed and sidewalls were due to the higher shear strength and well-drained hydraulic properties of the sandy soil compared to the black-soil.An infinite model was chosen to examine the temporal order of the mass wasting in the two gullies.It was found that the mass wasting in gully 2 occurred earlier than that in gully 1.This was likely due to the occurrence of an intense storm with less rainfall at the location of gully 2,while a light storm with heavier rainfall occurred in the location of gully 1.As Mollisols and sandy soil are the typical soil horizons in the Mollisols region worldwide,the results of this work could provide insightful knowledge for understanding the physical process of permanent gully expansion,which may be helpful for developing prediction models for sediment losses in some watersheds with vast Mollisols and highly developed gully system. 展开更多

Zinc,an essential trace element,plays a pivotal role in maintaining animal health and physiological functions.This review comprehensively examines zinc metabolism—including absorption dynamics across species(poultry,ruminants,and non-ruminants),transport mechanisms,storage in tissues,e.g.,the liver,and excretion pathways—and its multifaceted effects on animal health.Zinc critically regulates aspects of growth and development,particularly bone formation,as its deficiency induces skeletal deformities in young animals.It modulates immune function through zinc finger proteins,influencing immune organ integrity,lymphocyte proliferation,and cytokine expression.Reproductive performance is significantly affected by zinc,with its deficiency causing impaired spermatogenesis;delayed sexual maturity in males;and reduced litter size,embryonic survival,and placental function in females.At the molecular level,zinc regulates the activity of enzymes(e.g.,SOD),signaling pathways(MAPK,NF-κB),and transcription factors(MTF-1,Sp1)to maintain homeostasis.Both zinc deficiency(due to dietary insufficiency,malabsorption,or physiological stress)and zinc excess(from environmental pollution or feed oversupplementation)adversely affect health,disrupting mineral balance,enzyme function,and gut microbiota.In animal production,inorganic(zinc oxide,zinc sulfate)and organic(zinc methionine)sources of zinc increase growth,immunity,and productivity,although sustainable strategies are needed to mitigate environmental risks.Future research should focus on novel zinc formulations,precision nutrition,and interactions with gut microbiota to optimize livestock health and sustainable husbandry. 展开更多

The western Los Angeles(LA)wildfires of early January 2025 caused catastrophic social and environmental impacts,drawing widespread attention.This study investigates the characteristics of these wildfires and quantifies the influence of heat and drought on their likelihood using a copula-based Bayesian probability framework.The wildfires were characterized by burned area(BA)and intensity(fire radiative power,FRP).The criteria establishing the presence of“hot drought”conditions were identified using the 5-day Standardized Temperature Index(STI)and 75-day Standardized Precipitation Index(SPI),respectively.The wildfire outbreak began on 7 January 2025 and burned for more than six days,with the total burned area exceeding 245 km^(2) and the cumulative FRP exceeding 41060 MW.Based on satellite-derived active fire observations from 2001 to 2025,we estimate that such large and intense wildfires during LA’s rainy season represent a once-in-a-67-year event.The wildfires were largely driven by the combination of hot and dry conditions,which dried out soils and vegetation that had proliferated due to above-average precipitation in previous winter seasons,thereby providing abundant fuel.Our seasonal analysis reveals that extreme drought increased the probability of wildfires matching the 2025 intensity and BA by 54%and 75%,respectively.Hot drought further amplified these probabilities by 149%(intensity)and 210%(BA).These findings suggest an elevated risk of large wildfires under hot drought conditions,contributing to their expansion into the non-traditional fire season. 展开更多

With the continuous control of anthropogenic emissions,China’s air quality has improved significantly in recent years.Given this background,research on how the short-term exposure risks caused by air pollution in China have changed is insufficient.This study utilized hourly concentration data from ground observation stations and the official air quality guidelines of the Ministry of Ecology and Environment of China and the World Health Organization as standards to systematically investigate the spatiotemporal characteristics and short-term exposure risks of air pollution in China from 2015 to 2022.The results indicate that various atmospheric pollutants except for ozone showed a decreasing trend yearly.Nationwide,both single pollutant air pollution days(SAPDs)and multiple pollutant air pollution days(MAPDs)showed varying degrees of reduction within 15 and 25 days,respectively.SAPD was dominated mainly by excessive PM_(2.5)and PM_(10)pollutants,while MAPD was dominated mainly by excessive pollutant combinations,including PM_(2.5)+PM_(10),CO+PM_(2.5)+PM_(10),and SO_(2)+PM_(2.5)+PM_(10).As the concentration of atmospheric pollutants decreased,the total excess risk(ER)decreased yearly from 2015 to 2022,but there were significant regional differences.Now,the ER is less than 0.25%in southern China,in the range of 0.25%-0.5%in the North China Plain and some cities in the northeast,and higher than 1%in the northwest.Particulate matter is currently the primary pollutant posing short-term exposure risk in China,especially due to the impact of sandstorm weather.This study indicates that China’s atmospheric cleaning action is significantly beneficial for reducing health risks. 展开更多

Anaerobic digestion(AD)is widely employed for sludge stabilization and waste reduction.However,the slow hydrolysis process hinders methane production and leads to prolonged sludge issues.In this study,an efficient and eco-friendly lysozyme pre-treatment method was utilized to address these challenges.By optimizing lysozyme dosage,hydrolysis and cell lysis were maximized.Furthermore,lysozyme combined with hydrothermal pretreatment enhanced overall efficiency.Results indicate that:(1)When lysozyme dosage reached 90 mg/g TS after 240 min of pretreatment,SCOD,soluble polysaccharides,and protein content reached their maxima at 855.00,44.09,and 204.86 mg/L,respectively.This represented an increase of 85.87%,365.58%,and 259.21%compared to the untreated sludge.Threedimensional fluorescence spectroscopy revealed the highest fluorescence intensity in the IV region(soluble microbial product),promoting microbial metabolic activity.(2)Lysozyme combined with hydrothermal pretreatment significantly increased SCOD,soluble proteins,and polysaccharide release from sludge,reducing SCOD release time.Orthogonal experiments identified Group 3 as the most effective for SCOD and soluble polysaccharide release,while Group 9 released the most soluble proteins.The significance order of factors influencing SCOD,soluble proteins,and polysaccharide release is hydrothermal temperature>hydrothermal time>enzymatic digestion time.(3)The lysozyme-assisted hydrothermal pretreatment group exhibited the fastest release and the highest SCOD concentration of 8,135.00 mg/L during anaerobic digestion.Maximum SCOD consumption and cumulative gas production increased by 95.89%and 130.58%,respectively,compared to the control group,allowing gas production to conclude 3 days earlier. 展开更多

Precipitation isotopes(δ^(18)O and δ^(2)H)are closely related to meteorological conditions for precipitation generation and the initial state of water vapor source areas,and are essential to the study of the regional hydrological cycle.The deuterium excess(d-excess)indicates deviation in isotope fractionation during evaporation and can trace water vapor sources.This study analyzed 443 precipitation samples collected from the Gannan Plateau,China in 2022 to assess precipitation isotope variations and their driving factors.Water vapor sources were evaluated using the Hybrid Single-Particle Lagrangian Integrated Trajectory(HYSPLIT),Concentration Weighted Trajectory(CWT),and Potential Source Contribution Factor(PSCF)models.Results showed that precipitation isotope values showed significant spatial and temporal variations on the Gannan Plateau.Temporally,precipitation isotope values peaked in June(when evaporation dominated)and minimized in March(depletion effect of air masses in the westerly wind belt).Spatially,the isotope values showed a distribution pattern of"high in the east and low in the west",which was mainly regulated by the differences in altitude and local meteorological conditions.Compared with the global meteoric water line(GMWL)with equation of δ^(2)H=8.00δ^(18)O+10.00,the slope and intercept of local meteoric water line(LMWL)for precipitation on the Gannan Plateau were smaller(7.49 and 7.63,respectively),reflecting the existence of a stronger secondary evaporation effect under the clouds in the region.The sources of water vapor on the Gannan Plateau showed significant seasonality and spatial heterogeneity.Specifically,the westerly belt and monsoon were the main water vapor transport paths at each sampling point,with Central Asian continental water vapor dominating in spring(53.49%),Indian Ocean water vapor dominating in summer(52.53%),Atlantic Ocean water vapor dominating in autumn(46.74%),and Atlantic Ocean and Mediterranean Sea water vapor dominating in winter(42.30%and 33.68%,respectively).Changes in the intensity of convective activity and Outgoing Longwave Radiation(OLR)affected the enrichment of isotopic values,which exhibited the same change trends as δ^(18)O.During the precipitation process,the δ^(18)O value first decreased and then increased.During the initial and final stages of precipitation process,precipitation was mainly influenced by continental air masses,while during the middle stage,it was controlled by marine air masses.The systematic research on precipitation isotopes and water vapor sources is important for climate change research and extreme precipitation prediction on the Gannan Plateau and other similar areas. 展开更多

[Objective]Under the combined impact of climate change and urbanization,urban rainstorm flood disasters occur frequently,seriously restricting urban safety and sustainable development.Relying on traditional grey infrastructure such as pipe networks for urban stormwater management is not enough to deal with urban rainstorm flood disasters under extreme rainfall events.The integration of green,grey and blue systems(GGB-integrated system)is gradually gaining recognition in the field of global flood prevention.It is necessary to further clarify the connotation,technical and engineering implementation strategies of the GGB-integrated system,to provide support for the resilient city construction.[Methods]Through literature retrieval and analysis,the relevant research and progress related to the layout optimization and joint scheduling optimization of the GGBintegrated system were systematically reviewed.In response to existing limitations and future engineering application requirements,key supporting technologies including the utilization of overground emergency storage spaces,safety protection of underground important infrastructure and multi-departmental collaboration,were proposed.A layout optimization framework and a joint scheduling framework for the GGB-integrated system were also developed.[Results]Current research on layout optimization predominantly focuses on the integration of green system and grey system,with relatively fewer studies incorporating blue system infrastructure into the optimization process.Moreover,these studies tend to be on a smaller scale with simpler scenarios,which do not fully capture the complexity of real-world systems.Additionally,optimization objective tend to prioritize environmental and economic goals,while social and ecological factors are less frequently considered.Current research on joint scheduling optimization is often limited to small-scale plots,with insufficient attention paid to the entire system.There is a deficiency in method for real-time,automated determination of optimal control strategies for combinations of multiple system facilities based on actual rainfall-runoff processes.Additionally,the application of emergency facilities during extreme conditions is not sufficiently addressed.Furthermore,both layout optimization and joint scheduling optimization lack consideration of the mute feed effect of flood and waterlogging in urban,watershed and regional scales.[Conclusion]Future research needs to improve the theoretical framework for layout optimization and joint scheduling optimization of GGB-integrated system.Through the comprehensive application of the Internet of things,artificial intelligence,coupling model development,multi-scale analysis,multi-scenario simulation,and the establishment of multi-departmental collaboration mechanisms,it can enhance the flood resilience of urban areas in response to rainfall events of varying intensities,particularly extreme rainfall events. 展开更多

Cardiorenal syndrome reflects a complex interplay between cardiac and renal dysfunction,often compounded by fragmented management between cardiology and nephrology.Traditional phrases such as“the heart likes it dry and the kidneys like it wet”oversimplify care and perpetuate misconceptions about diuretic use and fluid management.Emerging evidence points to venous congestion rather than reduced cardiac output as a key driver of worsening renal function and adverse outcomes in heart failure.This article blends current evidence with the authors’perspective and clinical experience to explore the role of point-of-care ultrasound(POCUS)in the hemodynamic assessment of cardiorenal dysfunction,highlighting practical frameworks and tools.Conventional bedside assessment tools are limited,and static markers such as serum creatinine and physical signs can be misleading.POCUS provides a dynamic,physiology-based evaluation by integrating focused cardiac imaging,venous Doppler,lung ultrasound,and abdominal views.Frameworks such as“pump,pipes,and leaks”and scoring systems like venous excess ultrasound enable realtime visualization and quantification of congestion,shifting practice from assumption-based to data-driven care and fostering alignment between specialties.As training opportunities expand and supporting evidence grows,POCUS should be regarded as a core clinical skill in the management of cardiorenal dysfunction,with the potential to improve diagnostic precision and guide targeted therapy. 展开更多

Advancements in healthcare technology have improved mortality rates and extended lifespans,resulting in a population with multiple comorbidities that complicate patient care.Traditional assessments often fall short,underscoring the need for integrated care strategies.Among these,fluid management is particularly challenging due to the difficulty in directly assessing volume status especially in critically ill patients who frequently have peripheral oedema.Effective fluid ma-nagement is essential for optimal tissue oxygen delivery,which is crucial for cellular metabolism.Oxygen transport is dependent on arterial oxygen levels,haemoglobin concentration,and cardiac output,with the latter influenced by preload,afterload,and cardiac contractility.A delicate balance of these factors ensures that the cardiovascular system can respond adequately to varying ph-ysiological demands,thereby safeguarding tissue oxygenation and overall organ function during states of stress or illness.The Venous Excess Ultrasound(VExUS)Grading System is instrumental in evaluating fluid intolerance,providing detailed insights into venous congestion and fluid status.It was originally developed to assess the risk of acute kidney injury in postoperative cardiac patients,but its versatility has enabled broader applications in nephrology and critical care settings.This mini review explores VE×US’s application and its impact on fluid management and patient outcomes in critically ill patients. 展开更多

Anaerobic fermentation is an efficient method to extract phosphorus from excess sludge,thereby facilitating its recovery and mitigating the phosphorus resource shortage.However,the prevalent metal-bound phosphorus species within sludge was difficult to release into the fermentation liquor.To address this,this study evaluated the enhanced phosphorus release performance from sludge containing iron-phosphorus compounds(Fe-P)via co-fermenting it with agriculture wastes.Specifically,protein-rich feather(Feather Group)and polysaccharide-rich tea residue(Tea Group)was respectively dosed into batch-scale fermentation jar.Results showed that the Feather Group exhibited significantly higher levels of released soluble phosphorus(2.1 folds)and volatile fatty acids(41.4 folds)compared to the Control Group,with concentrations reaching up to 280 mg/L and 9366 mg chemical oxygen demand/L,respectively.The activities ofα-glucosidase,neutral protease and acetate kinase in the Feather group were increased by 11.1%,92.3%and 37.6%,respectively,compared with the Control group.Methanogen abundance decreased while hydrolytic acid-producing bacteria and iron-reducing bacteria increased significantly after supplying agricultural wastes.Metagenomic analysis demonstrated a significant increase in genes related to acetic acid synthesis.Mechanism elucidation suggested that increased iron-reducing bacteria abundance promoted Fe3+reduction into Fe2+,thus enhancing phosphorus release from Fe-P compounds.This work may provide valuable information for developing effective strategy to extract phosphorus resource from complex environmental wastes. 展开更多

Density(p)and speed of sound(u)findings on the binary liquid mixtures consisting of cyclohexanol(CH—OH),with aniline(A),ortho-chloroaniline(o-CA),and meta-chloroaniline(m-CA)were gathered at the various temperatures spanning the entire concentration range.303.15,308.15,313.15 and 318.15 K at atmospheric pressure.The information measured there was utilized to compute excess molar volume(V_(m)^(E)),excess isentropic compressibility(K_(S)^(E)),excess of speed of sound(u^(F)),excess intermolecular free length(L_(f)^(F))and excess acoustic impedance(Z^(F)).Further,the partial molar volumes(^(-)V°_(m,1).^(-)V°_(φ,1).^(-)V°_(m,2).^(-)V°_(φ,2)),partial molar compressibilities(K°_(m,1).^(-)K°_(φ,1).^(-)K°_(m,2).^(-)K°_(φ,2))and their excess values(^(-)V^(E)_(m,1).^(-)V^(°E)_(φ,1).^(-)V^(E)_(m,2).^(-)V^(°E)_(φ,2)),(K^(E)_(m,1).^(-)K^(°E)_(φ,1).^(-)K^(E)_(m,2).^(-)K^(°E)_(φ,2))were also computed to perceive more information on molecular interaction and structural effects in these mixtures.Applying the theory of Prigogine-Flory-Patterson(PFP)as a framework,the V_(m)^(E)data of the current liquid mixtures were examined.The analysis of the experimental data took into consideration the interactions that occur between the individual molecules that make up liquid mixtures.By using density functional theory DFT(B3LYP)of 6-31++G(d,P)to analyze the geometries,bond characteristics,interaction energies,and hydrogen bonded complexes in organic solvent phase,quantum chemical calculations were able to further confirm the hydrogen bonding that predominates between cyclohexanol with aniline and chlorosubstituted anilines. 展开更多

BACKGROUND One-anastomosis gastric bypass(OAGB)and sleeve gastrectomy(SG)are surgical procedures increasingly performed for weight loss and to achieve remission of diabetes mellitus.Literature comparing the medium-term efficacy of these two procedures is scarce.As such,a meta-analysis comparing OAGB and SG in terms of diabetes remission(DR)and percentage of excess weight loss(EWL)is warranted.AIM To compare OAGB and SG in terms of DR and EWL%in the medium term.METHODS A comprehensive literature search was conducted in PubMed/MEDLINE,Cochran Library,and Web of Science for relevant articles,from inception through April 2025,using the keywords“one-anastomosis gastric bypass”,“sleeve gastrectomy”,“mini-gastric bypass”,“diabetes remission”,“one-anastomosis”,and“excess weight loss”.Clinical trials,prospective,retrospective and case-control studies were included;cross-sectional studies,case reports,editorials,and opinions were excluded.The Cochrane Risk of Bias Tool and the Newcastle-Ottawa Scale were used to assess the quality of included studies,and RevMan version 5.4 was used for data analyses.RESULTS A total of 1360 articles were identified,and 35 studies were retrieved of which 32 were included in the final analysis.Three full texts were excluded as they did not include data on DR or EWL%.OAGB achieved higher DR than SG at 1 year following surgery[odds ratio(OR)=1.77,95%confidence interval(CI):1.22-2.57,I^(2)=76%].However,DR rates were similar at 3 years and 5 years following surgery(OR=0.82,95%CI:0.61-1.10,I^(2)=23%and OR=0.92,95%CI:0.31-2.72,I^(2)=75%,respectively).OAGB showed higher EWL%at 1 year(OR=9.30,95%CI:6.45-12.15,I^(2)=91%),3 years(OR=10.02,95%CI:9.40-10.64,I^(2)=22%),and 5 years(OR=11.61,95%CI:3.74-19.48,I^(2)=97%).OAGB showed higher late complications than adjustable SG.The results were not different in sub-group analysis including only clinical trials,observational studies,and removing studies including super-obese patients and studies contributing most to heterogeneity.CONCLUSION In the medium term,DR rates were similar between OAGB and SG;however,OAGB showed higher EWL%than SG,and late complications were higher in OAGB.Clinical trials investigating the predictors of DR and EWL%are recommended. 展开更多

Seismic-induced liquefaction of sandy soils can fail foundations in the vicinity of buildings.To investigate the effect of a non-free field subsurface seismic history on the ability of saturated sandy soils to resist liquefaction,four shaking events with different accelerations were input to the sandy soils in the non-free-field.The results of the study revealed that:(1)Shallow soils that are not free-field undergo acceleration amplification effects after being subjected to seismic loading.(2)Building overburden pressure reduces the sensitivity of the shallow soils directly below in small and moderate earthquakes,which are more prone to rearranging and forming unstable structures under strong seismic effects.The excess pore pressure response on the load side resembles that of a free site,with the depth range of the liquefaction strength of soils affected by the seismic history,increasing progressively as input seismic intensity increases.(3)After experiencing earthquakes of different intensities,the excess pore pressure directly below the building overburden pressure at 0.1 m and 0.2 m is greater than that at the side.At the same time,the side of the building structure is more prone to liquefaction than the soil directly below it. 展开更多
