Groundwat.r flows play a key role in t.e recharge of aquifers, t.e t.ansport.of solut.s t.rough subsurface syst.ms or t.e cont.ol of surface runoff. Predict.ng t.ese processes requires t.e use of groundwat.r models wit. t.eir applicabilit. direct.y linked t. t.eir accuracy and comput.t.onal efficiency. In t.is paper, we present.a new met.od t. model wat.r dynamics in variably- sat.rat.d porous media. Our model is based on a fully-explicit.discont.nuous-Galerkin formulat.on of t.e 3D Richards equat.on, which shows a perfect.scaling on parallel archit.ct.res. We make use of an adapt.d jump penalt. t.rm for t.e discont.nuous-Galerkin scheme and of a slope limit.r algorit.m t. produce oscillat.on-free exact.y conservat.ve solut.ons. We show t.at.such an approach is part.cularly well suit.d t. infilt.at.on front.. t.e model result. are in good agreement.wit. t.e reference model Hydrus-lD and seem promising for large scale applicat.ons involving a coarse represent.t.on of sat.rat.d soil.

Lysozyme is a nat.rally occurring enzyme found in bodily secret.ons such as t.ars, saliva, and milk. It.funct.ons as an ant.microbial agent.by cleaving t.e pept.doglycan component.of bact.rial cell walls, which leads t. cell deat.. Ant.biot.cs are also ant.microbials and have been fed at.subt.erapeut.c levels t. swine as growt. promot.rs. t.ese compounds benefit.swine producers by minimizing product.on losses by increasing feed efficiency and decreasing suscept.bilit. t. bact.rial infect.on and disease. t.is manuscript.reviews t.e knowledge of t.e effect. of lysozyme, as compared t. t.adit.onal subt.erapeut.c ant.biot.cs in swine feed, on pig performance and healt.. It.is clear from decades of st.dies t.at.ant.biot.c use in feeds increases pig performance, part.cularly in t.e nursery. Similarly, lysozyme, as a feed addit.ve, increases growt. and feed efficiency. While t.e mechanism by which ant.biot.cs and lysozyme improve performance is not.clearly underst.od, bot. of t.ese feed addit.ves improve gast.oint.st.nal healt., improve t.e met.bolic profile, and alt.r t.e gast.oint.st.nal bact.ria ecology of swine. t.erefore, lysozyme is a suit.ble alt.rnat.ve t. growt.-promot.ng subt.erapeut.c ant.biot.c use in swine feed.

We report.t.e t.ansient.effect. in erbium Doped Fiber Amplifier (eDFA) syst.ms for pulsed signals wit. different.dut.-cycles. t.e work includes t.e analysis using t.ree different.dut.-cycles, 10%, 20% and 50%. A curve fit.ing t.chnique is also proposed t. predict.t.e t.ansient. of any lesser dut.-cycled pulse, once t.e t.ansient. of a larger dut.-cycled pulse is known. Mat.emat.cal evaluat.on confirms t.e double exponent.al shape of t.ansient.dist.rt.d signal. Furt.er, eDFA t.ansient.effect.is experiment.lly verified on a Wavelengt.

We conclude t.e paper by proposing a t.ansient.suppression t.chnique for variable dut.cycle signals and analyzing it. effect.veness wit. different.wavelengt. spacing.

Arsenic cont.minat.on of global wat.r supplies has come t. t.e forefront.in policy decisions in recent.decades. However, t.e effect. of arsenic on lower t.ophic levels of insect. inhabit.ng cont.minat.d ecosyst.ms are not.well underst.od. One approach t. document.bot. acut. and sublet.al effect. of t.xicant. like arsenic is t. assay t.em in combinat.on wit. microbial pat.ogens t. evaluat. shift. in survival curves of t.e t.st.organisms. Larvae of Culex quinquefasciat.s and Culex t.rsalis were reared in wat.r cont.ining 0 or 1 000μg/L of arsenat. or arsenit.. Fourt. inst.rs were t.en exposed t. a range of doses of Bacillus t.uringiensis subsp, israelensis （Bt.） or Lysinibacillus sphaericus （Ls）, wit. shift. in let.al concent.at.ons det.rmined. Arsenic accumulat.on in 4t. inst.rs was also quant.fied, and a relat.ve growt. index （RGI） calculat.d for t.e t.eat.ent. and compared t. cont.ols. Larvae of bot. species accumulat.d bet.een 4 447 ± 169 ng As/g and 6 983 4- 367 ng As/g, t.ough RGI values indicat.d accumulat.on did not.affect.growt. and development. In all cases, t.e LC50＇s and LC90＇s of Cx. quinquefasciat.s exposed joint.y wit. arsenic and Bt./Ls were higher t.an Cx. t.rsafis. Cx. t.rsafis reared in arsenit. showed a significant.reduct.on in t.eir Bt. LC90 values compared t. t.e cont.ol, indicat.ng a sublet.al effect.of Bt.. When exposed joint.y wit.
