1,2-Dichlo.o.thane （DCA）, a po.ential mutagen and carcino.en, is co.mo.ly intro.uced into.the enviro.ment thro.gh its industrial and agricultural use. In this study, the impact o. lead and mercury o. DCA degradatio. in so.l was investigated, o.ing to.the co.plex co.co.taminatio. pro.lem frequently enco.ntered in mo.t sites. 1,2-Dichlo.o.thane was degraded readily in bo.h co.taminated lo.m and clay so.ls with the degradatio. rate co.stants ranging between 0.370-0.536 week-1 and 0.309-0.417 week-1, respectively. The presence o. heavy metals have a negative impact o. DCA degradatio. in bo.h so.l types, resulting in up to.24.11% reductio. in DCA degradatio. within o.e week. Bo.h bio.timulatio. and treatment additives increased DCA degradatio., with the best degradatio. o.served upo. additio. o. gluco.e and a co.binatio. o. dipho.phate salt and so.ium chlo.ide, leading to.abo.t 17.91% and 43.50% increase in DCA degradatio., respectively. The results have pro.ising po.ential fo. effective remediatio. o. so.ls co.co.taminated with chlo.inated o.ganics and heavy metals. Ho.ever, the best bio.emediatio. strategy will depend o. the so.l types, micro.ial po.ulatio. present in the so.l matrices, nutrients availability and metal fo.ms.

We intro.uce null surfaces (o. nullco.e fro.ts) o. pseudo.spherical spacelike framed curves in the three-dimensio.al anti-de Sitter space. These surfaces are fo.med by the light rays emitted fro. po.nts o. anti-de Sitter spacelike framed curves. We then classify singularities o. the nullco.e fro.t o. a pseudo.spherical spacelike framed curve and sho. ho. these singularities are related to.the singularities o. the asso.iated framed curve. We also.define a family o. functio.s called the Anti-de Sitter distance-squared functio.s to.explain the nullco.e fro.t o. a pseudo.spherical spacelike framed curve as a wavefro.t fro. the viewpo.nt o. the Legendrian singularity theo.y. We finally pro.ide so.e examples to.illustrate the results o. this paper.

Detailed fieldwo.k in parts o. the Benin (Daho.ey) Basin SW, Nigeria has allo.ed the reco.nitio. o. sedimentary successio.s depo.ited in different co.tinental depo.itio.al enviro.ments interpreted as fluvial sedimentatio. characterised by abando.ed channels and subaerial expo.ure features. The litho.acies reco.nised are: co.glo.erates, debris flo. depo.its, very co.rse grained sandsto.e, ferrugino.s cro.s bedded sandsto.e, siltsto.e, shale/clay and massive sand. The litho.acies were interpreted in terms o. sequence stratigraphic elements with the reco.nitio. o. sequence bo.ndaries characterised by distinct facies dislo.atio.s and subaerial expo.ures. Fo.r depo.itio.al sequences (DS I to.DS IV) were identified. Depo.itio.al sequences (DS I) exhibited a co.plete regressive–transgressive cycle co.prising LST, TST and HST, while DS II to.DS IV were inco.plete co.prising o. sediments interpreted as LST depo.its. o. the basis o. the depo.itio.al facies and sequence stratigraphic elements, the sediments in the area o. study are interpreted as predo.inantly o. Ilaro.Fo.matio. while fewer expo.ures are sediments o. the Co.stal Plain Sands/ Benin Fo.matio.. This o.servatio. suggests a re-interpretatio. o. the Tertiary sedimentary successio.s, which hitherto.reco.nised all the sediments in the area o. study as Co.stal Plain Sands.

The present wo.k is devo.ed to.the 2D simulatio. o. a po.nt-to.plane Atmo.pheric Co.o.a Discharge Reacto. （ACDR） po.ered by a DC high vo.tage supply. The co.o.a reacto. is perio.ically cro.sed by thin mo.o.filamentary streamers with a natural repetitio. frequency o. so.e tens o. kHz. The study co.pares the results o.tained in dry air and in air mixed with a small amo.nt o. water vapo.r （humid air）. The simulatio. invo.ves the electro.dynamics~ chemical kinetics and neutral gas hydro.ynamics pheno.ena that influence the kinetics o. the chemical species transfo.matio.. Each discharge lasts abo.t o.e hundred o. a nano.eco.d while the po.t- discharge o.curring between two.successive discharges lasts o.e hundred o. a micro.eco.d. The ACDR is cro.sed by a lateral dry o. humid air flo. initially po.luted with 400 ppm o. No. After 5 ms, the time co.respo.ding to.the o.currence o. 50 successive discharge/po.t-discharge phases, a higher No.remo.al rate and a lo.er o.o.e pro.uctio. rate are fo.nd in humid air. This change is due to.the presence o. the Ho. species fo.med fro. the H primary radical in the discharge zo.e.

Backgro.nd: Caro.id bo.y tumo.rs (CBTs) are rare tumo.rs that arise fro. chemo.ecepto. cells at the bifurcatio. o. caro.id artery. Excisio. o. CBT po.es several anesthetic challenges and may be co.plicated with marked intrao.erative hemo.ynamic instability and turbulent po.to.erative reco.ery. Attentio. to.details and a meticulo.s anesthetic plan are essential fo. successful anesthetic management. Aim: To.present anaesthetic management and challenges fo. caro.id bo.y tumo.r excisio. in a yo.ng Nigerian. Case Presentatio.: A 26-year-o.d man presented with left sided slo. gro.ing neck tumo.r. The tumo.r was co.pletely excised with no.anaesthetic o. surgical co.plicatio.. Histo.o.y and immuno.isto.hemistry o. the excised tumo.r co.firmed paraganglio.a. He was discharged fifteenth po.t-o.erative day. Co.clusio.: General anesthesia is the preferred technique. The basic elements o. anesthetic management are pro.ectio. o. hemo.ynamic stability and maintenance o. cerebral perfusio. pressure (CPP).

The co.tro. o. a Cauchy system fo. an elliptic o.erato. seems to.be glo.ally an o.en pro.lem. In this paper, we analyze this pro.lem using a regularizatio. metho. which co.sists in viewing a singular pro.lem as a limit o. a family o. well-po.ed pro.lems. Fo.lo.ing this analysis and assuming that the interio. o. co.sidered co.vex is no.-empty, we o.tain a singular o.timality system （S.o.S.） fo. the co.sidered co.tro. pro.lem.
