Bac.ground: Termination of pregnanc. (TOP) in Zambia is.guided by the Termination of Pregnanc. (TOP) Ac. of 1972 and as.amended in 1994 of the laws.of Zambia. However, des.ite provis.on of c.mprehens.ve abortion c.re s.rvic.s.with the liberal law, s.atis.ic. at Kanyama Firs. Level Hos.ital in relation to uns.fe illegal abortions.are alarming. This.s.udy s.ught to unders.and the Awarenes. on the TOP Ac. of the laws.of Zambia among women of reproduc.ive age 15 - 49 years.at Kanyama Firs. Level Hos.ital in Lus.ka Dis.ric.. Purpos. of the s.udy: To as.es. awarenes. on the TOP Ac. among women of reproduc.ive age at Kanyama Firs. Level Hos.ital in Lus.ka, Zambia. Methodology: A c.nvergent parallel mixed method des.gn was.c.nduc.ed us.ng both s.rvey and in-depth interviews.among women of reproduc.ive age at Kanyama Firs. Level Hos.ital in Lus.ka Dis.ric.. The s.udy s.rveyed 370 randomly s.mpled women aged 15 to 49 years.old while the in-depth interviews.inc.uded eight women purpos.vely s.mpled from the s.rvey population. s.rvey data was.analyzed us.ng des.0}iptive and inferential s.atis.ic. while qualitative data thematic.analys.s.was.us.d. Res.lts. The s.udy found that 37% of the partic.pants.were aware of the TOP Ac. while 63.8% viewed legalization of abortion for any reas.n as.wrong. The s.udy res.lts.als. s.owed that widowed women were 8 times.more likely to be aware of the TOP Ac. c.mpared to s.ngle women (AOR: 8.262;95% c.: 1.105, 61.778). Women in bus.nes. were s.gnific.ntly more likely to be aware of the TOP Ac. c.mpared to thos. who reported having no oc.upation. (AOR: 2.61;95% c.: 1.246, 5.499). Limited ac.es. to information, the s.c.al s.igma attac.ed to abortion, health c.re providers. attitudes. c.ltural norms. values.and religious.beliefs. res.ric.ive legal requirements. and abs.nc. of a s.pportive network were s.me of the barriers.affec.ing awarenes. and utilization of available s.fe abortion c.re s.rvic.s. c.nc.us.ons.

Bac.ground: Elas.omeric.pumps.(elas.ic.balls.into whic. analges.c. or antibiotic. c.n be ins.rted) pus. medic.nes.through a c.theter to a nerve or blood ves.el. s.nc. elas.omeric.pumps.are s.all and need no power s.urc., they fit eas.ly into a poc.et during infus.on, allowing patient mobility. Elas.omeric.pumps.are widely us.d and widely s.udied experimentally, but they have well-known problems. s.c. as.maintaining reliable flow rates.and avoiding toxic.ty or other peak-and-trough effec.s. Objec.ives. Our res.arc. objec.ive is.to develop a realis.ic.theoretic.l model of an elas.omeric.pump, analyze its.flow rates. determine its.toxic.ty c.nditions. and otherwis. improve its.operation. We believe this.is.the firs. s.c. theoretic.l model of an elas.omeric.pump c.ns.s.ing of an elas.ic. medic.ne-filled ball attac.ed to a horizontal c.theter. Method: Our method is.to model the s.s.em as.a quas.-Pois.uille flow driven by the pres.ure drop generated by the elas.ic.s.here. We c.ns.ruc. an engineering model of the pres.ure exerted by an elas.ic.s.here and matc. it to a s.lution of the one-dimens.onal radial Navier-s.okes.equation that des.0}ibes.flow through a horizontal, c.lindric.l tube. Res.lts. Our res.lts.are that the model ac.urately reproduc.s.flow rates.obtained in c.inic.l s.udies. We als. dis.0}ver that the flow rate has.an unavoidable maximum, whic. we c.ll the “toxic.ty bump”, when the radius.of the s.here approac.es.its.terminal, uns.retc.ed value—an effec. that has.been obs.rved experimentally. c.nc.us.ons. We c.nc.ude that by c.oos.ng the properties.of an elas.omeric.pump, the toxic.ty bump c.n be res.ric.ed to les. than 10% of the earlier, relatively c.ns.ant flow rate. Our model als. produc.s.a relation between the length of time that the analges.c.fluid infus.s.and the phys.c.l properties.of the fluid, of the elas.omeric.s.here and the tube, and of the blood ves.el into whic. the analges.c.infus.s.
