*** and context Enormous emphasis is currently.being paid to the decarbonization of the global built environment as a leading priority.for the engineering community.and related industrial sectors[1].One of the main contributors to the overall emissions footprint of the built environment-and thus a cornerstone of efforts to achieve decarbonization-is the emissions profile of construction materials during their production and *** cement and concrete sector is the largest-volume contributor to the emissions incurred in meeting the world’s construction material needs and is therefore targeted in the discussion of the deep,rapid decarbonization that must be achieved in order to minimize irreversible damage to the Earth and its ecosy.tems.

Background Agricul.ure has greatly.influenced water quality. habitats, and fish assemblages in streams of the Mississippi Al.uvial Plain(MAP) ecoregion. However, MAP streams have historically.been understudied compared to streams in other agricul.ural regions of the uSA. In this study. water quality. habitat, and fish assemblage composition were assessed seasonally.spring, summer, and fall) in eight representative MAP streams located across three u.S. states. The study.design included four streams containing highly.agricul.ural watersheds(herein termed “agricul.ure” streams) and four streams containing mostly.forested watersheds(herein termed “forest” streams), which were intended to represent reference conditions for MAP *** In general, forest streams contained significantly.better instream and riparian habitats than agricul.ure streams(P = 0.010–0.040) whereas agricul.ure streams contained significantly.greater levels of primary.nutrients(P ul.ure and forest streams with respect to other phy.ical and chemical variables were intermittent and season dependent. Fish assemblages in agricul.ure and forest streams were structured primarily.along an environmental gradient reflecting instream habitat conditions, water nutrient concentrations, and benthic chlorophy.l-a production. Structurally. fish assemblages in both stream ty.es contained many.regionally.common species, though some species appeared to exhibit affinities for a particular stream ty.e. Functionally. fish assemblages in agricul.ure streams contained more tolerant species, more omnivores, and fewer insectivores compared to forest stream assemblages, which were nearly.all insectivores. Overall, one-third of the fish specimens collected in forest streams classified as intolerant *** Our results suggested that stream water quality. habitat, and fish assemblages differed between agricul.ure and forest streams in the MAP, with fish assemblages e

漆酶是一种含铜的多酚氧化酶,在生物检测、工业染料脱色、有机农药降解、纸浆漂白及食品饮料等领域具有广泛的应用价值。本研究使用实验室自主筛选鉴定的漆酶高产菌株粗毛栓菌(Trametes hirsuta),液态发酵后,培养液经硫酸铵分级沉淀、DEAE Sepharose FF阴离子交换层析分离纯化,酶活总得率57.2%,纯化倍数6.0倍,比活力为758.5 u/mg,漆酶的分子量约为50 kDa。利用粗毛栓菌粗酶液分别对结晶紫、溴酚蓝、孔雀石绿、詹姆斯绿B进行脱色,同时研究了染料浓度、脱色温度、pH和NaCl对溴酚蓝和孔雀石绿脱色率的影响。结果表明,溴酚蓝和孔雀石绿浓度分别为40 mg/l和50 mg/l时脱色率较高;在脱色温度为50℃时,漆酶对溴酚蓝和孔雀石绿的脱色率较高,最高脱色率分别为68.51%和83.06%;溴酚蓝在pH 3.5时脱色率最高达到72.61%,而孔雀石绿的脱色率在pH 4.5时最高达到83.49%;NaCl对Trametes hirsuta漆酶催化染料脱色有一定的抑制作用。本研究表明Trametes hirsuta漆酶在染料脱色中具有较大的应用前景,在工业废水的处理中具有良好的应用潜力。

l x-ray.intensity.ratios le/lγ, lα/l7 and lβ/lγ for ^92u and ^90Th are measured by.using 59.5keV incident photon energy.at 110° and 125° scattering angles. The samples are located in the external magnetic field of intensities ±0.15T, ±0.30T, ±0.45T, ±0.60T and ±0.75T. The experimental results obtained for B = 0 are compared with the theoretical values cal.ulated using Scofield＇s tables based on the Hartree Slater theory. The contribution to the alignment of the external magnetic field is discussed. It is observed that the l x-ray.intensity.ratios decrease with the increasing magnetic field intensity.
