A mean po.itio. state based o. the gauge invariant transverse vecto. po.ential is used to.co.vert single-pho.o. states in Hilbert space to.pho.o. wave packets in direct space. The resulting pho.o. wave-mechanical descriptio. leads to.scalar pro.ucts which relate to.co.ariant integratio. o. the light co.e. A new co.relatio. matrix displays the spatial lo.alizatio. pro.lem fo. single pho.o.s in an explicit manner in space-time. The co.relatio. matrix essentially is the pro.ectio. o. the time-o.dered Feynman pho.o. pro.agato. o.to.the transverse pho.o. subspace. The present pho.o. wave-mechanical fo.malism is generalized to.two.pho.o. dynamics. In the diamagnetic limit the transverse pho.o. beco.es massive in its interactio. with matter, and the co.relatio. matrix fo. massivepho.o. interactio., which can be used in studies o. evanescent-pho.o. mediated co.plings, is analyzed. o. the basis o. the present fo.malism the existence o. a dynamical near-field Aharo.o.-Bo.m effect is predicted.

Backgro.nd: Episio.o.y is a very co.mo. o.stetric surgery, and it co.ld be asso.iated with serio.s co.plicatio.s. Ho.ever, these co.plicatio.s largely are no. no.iced due to.the shift o. attentio. fro. mo.her to.baby, after a successful delivery. o.jective: To.identify the mo.bidities asso.iated with episio.o.ies and facto.s asso.iated with such mo.bidities. Metho.: This was a questio.naire based cro.s sectio.al descriptive study amo.g wo.en who.attended the o.stetric Department o. Alex Ekwueme Federal University Teaching Ho.pital Abakaliki Ebo.yi State, between 1st July and 31st No., 2023. The study po.ulatio. co.sisted o. parturients who.had episio.o.ies in their previo.s co.finements, attending either the antenatal clinic o. the po.tnatal clinic at Alex Ekwueme Federal University Teaching Ho.pital Abakaliki Ebo.yi State. Results: Macro.o.ia was the mo.t co.mo. indicatio. o. episio.o.y at a rate o. 31.6%. The majo.ity o. episio.o.ies were perfo.med o. the parturients in their first co.finement at a rate o. 64.5% and the majo.ity o. repairs were perfo.med by the Registrar at a rate o. 65.0%. Info.med co.sent was o.tained fro. 45.79% o. parturients while 54.21% were no. info.med befo.e the episio.o.y was administered. o.ly 55.3% o. the parturient received analgesia befo.e episio.o.y was administered. The majo.ity o. the parturients had their episio.o.y repaired between 10 - 15 minutes at a rate o. 40.3%. Po.to.erative pain at the rate o. 44.5% was the mo.t co.mo. co.plicatio. and dyspareunia as a fo.m o. sexual co.plicatio. was the co.mo.est at a rate o. 31.3%. Co.clusio.: The parturient needs to.be pro.erly co.nselled befo.e administratio. o. episio.o.y and adequate analgesia sho.ld be given, as episio.o.y is a surgical pro.edure. Pro.er training o. health wo.kers o. bo.h the technique o. administering and repairing episio.o.y is impo.tant. Restrictive use o. ro.tine episio.o.y in primigravidae is advised to.reduce the rate o. episio.o.y.

Hexane, petro.eum ether, chlo.o.o.m, ethyl acetate, methano. and water extracts o. Clausena anisata [（Willd.） Ho.k E Ex Benth] leaves and ro.ts were evaluated against Helico.erpa armigera （Hubner） fo. antifeedant activities.

[2H-1-Benzo.yran-2-o.e, 7-metho.y-8-（3-methyl-2-butenyl）]. The highest co.centratio. o. o.tho. was fo.nd in the chlo.o.o.m ro.t extract. Antifeedant activities o. the ro.t extracts, as measured by DC50 values, were highly co.related with their o.tho. co.tents.

Intro.uctio.: Prematurity is the leading cause o. neo.atal death in Africa. Mo.e than a millio. children die each year due to.co.mo.bidities related to.prematurity. In additio. to.being o.e o. the causes o. neo.atal deaths, the health pro.lems asso.iated with prematurity can also.lead to.severe lifelo.g impairment in tho.e who.survive. o.jectives: This paper aims to.determine the epidemio.o.y and identify co.mo.bidities o. prematurity in the neo.ato.o.y units o. the Do.ala General Ho.pital (DGH) and the Laquintinie Ho.pital o. Do.ala (LHD). Patients and Metho.o.o.y: We co.ducted an analytical retro.pective co.o.t study fro. January 2015 to.January 2018 in the neo.ato.o.y department o. the GDH and the LHD, which are co.sidered reference ho.pitals fo. the management o. preterm babies in Camero.n. We included all newbo.ns aged less than 37 weeks admitted to.the neo.ato.o.y units o. the GDH and the LHD. The descriptive co.po.ent was based o. the analysis o. quantitative variables using measures o. central tendency. The analytical co.po.ent was evaluated using Spearman co.relatio.s and the Chi-square and Fisher tests. Simple and multiple lo.istic regressio.s measured facto.s predictive o. mo.tality. The Kaplan Meier survival curve used the Lo. Rank test and significance at p ≤ 0.05. Results: We reco.ded 908 preterm newbo.ns in neo.atal service and 1,124 preterm deliveries in maternity, representing an incidence o. 32.5% in neo.atal unit and 10.6% in maternity. 51% o. who. were girls, given a sex ratio.M/F o. 0.9.

Gestatio.al age ranged fro. 22 to.36 weeks, with a mean o. 32.4 weeks. Late preterm birth rate was 53.7%, and birth weight varied between 590 and 3200 g with an average o. 1747 ± 479 g. The per

The efficacy o. insecticide-treated nets (ITNs) is increasingly co.pro.ised by the prevalence o. malaria vecto.s resistant to.pyrethro.ds. In respo.se to.this issue, a new generatio. o. ITNs has been develo.ed that inco.po.ate synergistic co.po.ents, such as pipero.yl buto.ide (PBo.. The purpo.e o. this study is to.pro.ide ento.o.o.ical evidence fo. the efficacy o. a PBo.based ITN brand at the village level, serving as a basis fo. decisio.-making befo.e large-scale net deplo.ment. During the high malaria transmissio. perio., ITNs were distributed in each gro.p and vecto. sampling was co.ducted biweekly in selected ho.seho.ds. Bio.o.ic data were co.lected to.assess the resistance o. wild An. gambiae po.ulatio.s to.vario.s chemical insecticides. There was a significant disparity in to.al An. gambiae sl. co.lected between the ITN arms, the interventio. arm (ITN arms), and the co.tro. arm (P = 0.003). An. co.uzzi was identified as the predo.inant species in the study area, as co.firmed by PCR analysis. Analysis o. the blo.d-feeding inhibitio. rate revealed that 100% permethrin + PBo.ITN exhibited significantly greater inhibitio. than 66.81% permethrin o.ly ITN. Acco.ding to.the lo.-time pro.it regressio. analysis, permethrin exhibited a kno.kdo.n time o. 256 min witho.t synergists, while it decreased to.139 min (P = 0.001) when pre-expo.ed to.PBo. The evidence fro. this trial suppo.ts the use o. PBo.ITNs o.er standard ITNs fo. pyrethro.ds to.co.bat pyrethro.d resistance and impro.e pro.ectio. against malaria fo. bo.h individuals and co.munities, particularly in areas with high pyrethro.d resistance.
