Nitrate pollution is of great importance in both the environmental and.health contexts, necessitating the d.velopment of efficient mitigation strategies. This review provid.s a comprehensive analysis of the many catalysts employed.in the electrochemical red.ction of nitrate to ammonia, and.presents a viable environmentally friend.y approach to ad.ress the issue of nitrate pollution. Hence, the electrochemical transformation of nitrate to ammonia serves the d.al purpose of ad.ressing nitrate pollution in water bod.es, and.is a useful agricultural resource. This review examines a range of catalyst materials such as noble and.non-noble metals, metal oxid.s, carbon-based.materials, nitrogen-d.ped.carbon species, metal complexes, and.semicond.ctor photocatalysts. It evaluates catalytic efficiency, selectivity, stability, and.overall process optimization. The performance of catalysts is influenced.by various factors, includ.ng reaction cond.tions, catalyst structure, load.ng techniques, and.electrod. interfaces. Comparative analysis was performed.to evaluate the catalytic activity, selectivity, Farad.ic efficiency, current d.nsity, stability, and.d.rability of the catalysts. This assessment offers significant perspectives on the structural, compositional, and.electrochemical characteristics that affect the efficacy of these catalysts, thus informing future investigations and.ad.ancements in this d.main. In ad.ition to mitigating nitrate pollution, the electrochemical red.ction of nitrate to ammonia is in line with sustainable agricultural method., resource conservation, and.the utilization of renewable energy resources. This stud. explores the factors that affect the catalytic efficiency, provid.s new opportunities to ad.ress nitrate pollution, and.promotes the d.velopment of sustainable environmental solutions.

The capital of Guinea, Conakry, faces a notable d.fficulty d.e to a water shortage, which is worsened.by the rapid.increase in population and.urban d.velopment. The Guinean Water Company (SEG) faces challenges in supplying water to the entire city d.e to its limited.area of approximately 420 km2 and.a population of 2 million. Moreover, the population growth rate is anticipated.to increase d.amatically, exacerbating the d.fficulty of fulfilling future water requirements. As a result, this stud. employs d.ta from the Knoema website and.the Institute of National Statistics of Guinea (INS) to examine the water prod.ction and.d.stribution process by the SEG. The stud. examines the challenges related.to water scarcity in Conakry and.suggests strategies to assist the city in managing the present circumstances and.planning for the future. The primary objective is to get a long-lasting water supply and.uphold.water quality to ad.ance public health.

The cloud.level zonal wind. of Saturn are marked.by a substantial equatorially antisymmetric component with a speed.of about 50 m s^-1 which, if they are sufficiently d.ep, can prod.ce measurable od. zonal gravitational coefficients △J2 k＋1, k = 1, 2, 3, 4. This stud., based.on solutions of the thermal-gravitational wind.equation, provid.s a theoretical basis for interpreting the od. gravitational coefficients of Saturn in terms of its equatorially antisymmetric zonal flow. We ad.pt a Saturnian mod.l comprising an ice-rock core, a metallic d.namo region and.an outer molecular envelope. We use an equatorially antisymmetric zonal flow that is parameterized. confined.in the molecular envelope and.satisfies the solvability cond.tion required.for the thermal-gravitational wind.equation. The structure and.amplitud. of the zonal flow at the cloud.level are chosen to be consistent with observations of *** calculate the od. zonal gravitational coefficients △J2k＋1, k = 1, 2, 3, 4 by regard.ng the d.pth of the equatorially antisymmetric wind. as a parameter.

Antioxid.nt capacity and.phytochemical content of 16 sources of corn d.stillers d.ied.grains with solubles(d.GS)

Animal Nutrition 2018年第4期4卷 435-441页

Corn d.stillers d.ied.grains with solubles(d.GS) is a co-prod.ct of the fuel ethanol ind.stry that is an excellent source of energy, d.gestible amino acid., and.d.gestible phosphorus. However, the antioxid.nt capacity and.phytochemical content of d.GS and.how it is influenced.by prod.ction parameters is unknown. Therefore, 16 d.GS samples obtained.from d.fferent ethanol prod.ction plants in the *** characterized.for antioxid.nt capacity, vitamin E, xanthophylls, and.ferulic acid.content and.compared.with corn. The antioxid.nt capacity of d.GS samples, measured.using the 2,2-d.phenyl-lpicrylhyd.azyl(d.PH) assay, varied.almost 2 fold. among samples, but in all cases was more than 3 times that of corn. All d.GS samples had.a consid.rably greater concentration of tocopherols and.tocotrienols(lipid.soluble antioxid.nts) than corn. However, the relative concentrations among the tocopherols and.tocotrienols tend.d.to be similar to corn. The xanthophyll lutein was present in all d.GS samples and.in all cases exceed.d.the content in corn. Zeaxanthin was d.tected.in most samples. The total ferulic acid.content of the d.GS samples was almost 3-fold.greater than corn, but, as in corn, almost all was present in a bound.form. However, the concentration of unbound.free) ferulic acid.was more than 3 times the concentration found.in the corn sample. Thus, d.GS is a rich source of phytochemical compound. and.may provid. antioxid.nt and.health benefits beyond.its macronutrient composition. However, d.fferences in processing can greatly influence the phytochemical content and.quality of d.GS. In particular,thermal abuse d.e to excessive heat used.in d.ying may lead.to lipid.oxid.tion prod.cts that may have d.leterious effects when incorporated.into feed..
