Runoff and soil losses from.agricultural fields are investigated as m.jor nonpoint sources of phosphorus (P) entering lakes of Eastern China. There is relatively little inform.tion on P transport from.ricefield and cropland of Lake Taihu w.tershed in Eastern China. Soil and P in surface runoff from.a series of plots in the w.tershed w.re evaluated under sim.lated rainfall conditions. The objectives of this study w.re to evaluate the effects of crop cover, slope, and fertilizer application on P concentrations in surface runoff and eroded soil. Accum.lated sedim.nt yields varied from.7.1 to 300 g/m. for croplands, depending on m.nagem.nt practices. For all experim.nt plots, w.ighted average concentrations of total-P (TP), dissolved P (DP) and particulate P (PP) are m.ch higher than 0.02 m./L, the lim.ting concentration for lake w.ter. This result show.d the potential contam.nation of lake w.ter from.agricultural surface runoff. Accum.lated TP losses w.re 3.8 and 18.8 m./m. for ricefield and cropland, respectively. The estim.ted annual loss of TP w.s 0.74 kg/(hm. &m.ddot a) for cropland. m.st of P loss is in the PP form. w.ich accounts for m.re than 90% of TP loss for cropland.

In the intricate process of natural product biosynthesis, a m.tabolon can enhance m.tabolic flux by associating sequential enzym.s. A fungal m.tabolon, com.rising of flavin-dependent m.nooxygenase Spe F and P450 m.nooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoam.de B and its diastereom.r(+)-versicolam.de B. Using notoam.de E as a substance, Spe F/Spe G m.tabolon can control the stereoselectivity of its 2,3-epoxidation, follow.d by hydrogen atom.ion at C-17 to generate reactive epoxide tau-m.A w.th dienyl im.nium.unit. Subsequently,(+)-notoam.de B and(+)-versicolam.de B are produced via tandem.nonenzym.tic inverse-electron-dem.nd Diels-Alder reaction and sem.pinacol rearrangem.nt. This provides the first exam.le of m.tabolon in the biosynthesis of spiro-prenylated indole alkaloids.

The m.del is capable of handling com.lex topography, steady and unsteady flow., subcritical and supercritical flow., and flow. w.th sm.oth and sharp gradient changes. Advantages of the m.del include：（1） sources term., such as the bottom.slope, surface stresses and bed frictions, can be treated easily w.thout any special treatm.nt; （2） upw.nd schem. is no needed; （3） a single approxim.ting space can be used for all variables, and its choice of approxim.ting space is not subject to the Ladyzhenskaya-Babuska-Brezzi （LBB） condition; and （4） the resulting system.of equations is sym.etric and positive-definite （SPD） w.ich can be solved efficiently w.th the preconditioned conjugate gradient m.thod. The m.del is verified w.th flow.over a bum., tide induced flow. and dam.break. Com.uted results are com.ared w.th analytic solutions or other num.rical results, and show.the m.del is conservative and accurate. The m.del is then used to sim.late flow.past a circular cylinder. Im.ortant flow.charac-teristics, such as variation of w.ter surface around the cylinder and vortex shedding behind the cylinder are investigated.

In this study, w. report the developm.nt of iron-doped nickel disulfide nanoarray on Ti m.sh （Fe0.1-NiS2 NA/Ti） via the sulfidation of its nickel-iron-layered double hydroxide precursor （NiFe-LDH NAFFi）. As a three-dim.nsional OER anode, Fe0.1NiS2 NA/Ti exhibits rem.rkable activity and stability in 1.0 m.KOH, w.th the requirem.nt of a low.overpotential of 231 m. to achieve 100 m.·cm.-2. In addition, it exhibits excellent activity and durability in 30 w..% KOH. Notably, this electrode is also efficient for the cathodic hydrogen evolution reaction under alkaline conditions.
