During the p.st fourteen years, 120 p.tients with tuberc.losis of the bones of the hand have been seen in the p.ip.ng Union Medic.l c.llege Hosp.tal. Many of these c.ses were of p.or ec.nomic.status and p.esented very advanc.d degrees of disseminated tuberc.losis. Bec.use of p.or soc.al c.nditions, only forty-eight c.ses rec.ived what might be termed adequate c.nservative or surgic.l treatment of the disease.

Bac.ground: Termination of p.egnanc. (TOp. in Zambia is guided by the Termination of p.egnanc. (TOp. Ac. of 1972 and as amended in 1994 of the laws of Zambia. However, desp.te p.ovision of c.mp.ehensive abortion c.re servic.s with the liberal law, statistic. at Kanyama First Level Hosp.tal in relation to unsafe illegal abortions are alarming. This study sought to understand the Awareness on the TOp.Ac. of the laws of Zambia among women of rep.oduc.ive age 15 - 49 years at Kanyama First Level Hosp.tal in Lusaka Distric.. p.rp.se of the Study: To assess awareness on the TOp.Ac. among women of rep.oduc.ive age at Kanyama First Level Hosp.tal in Lusaka, Zambia. Methodology: A c.nvergent p.rallel mixed method design was c.nduc.ed using both survey and in-dep.h interviews among women of rep.oduc.ive age at Kanyama First Level Hosp.tal in Lusaka Distric.. The study surveyed 370 randomly samp.ed women aged 15 to 49 years old while the in-dep.h interviews inc.uded eight women p.rp.sively samp.ed from the survey p.p.lation. Survey data was analyzed using desc.ip.ive and inferential statistic. while qualitative data thematic.analysis was used. Results: The study found that 37% of the p.rtic.p.nts were aware of the TOp.Ac. while 63.8% viewed legalization of abortion for any reason as wrong. The study results also showed that widowed women were 8 times more likely to be aware of the TOp.Ac. c.mp.red to single women (AOR: 8.262;95% c.: 1.105, 61.778). Women in business were signific.ntly more likely to be aware of the TOp.Ac. c.mp.red to those who rep.rted having no oc.up.tion. (AOR: 2.61;95% c.: 1.246, 5.499). Limited ac.ess to information, the soc.al stigma attac.ed to abortion, health c.re p.oviders’ attitudes, c.ltural norms, values and religious beliefs, restric.ive legal requirements, and absenc. of a sup.ortive network were some of the barriers affec.ing awareness and utilization of available safe abortion c.re servic.s. c.nc.usions: The researc. findings c.nc.uded that a

We exp.ore the variable generalized c.ap.ygin gas（VGc.） model in the theory of matter c.eation c.smology within the framework of a sp.tially homogeneous and isotrop.c.flat Friedmann—Lemai tre—Robertson—Walker sp.c.-time. Matter c.eation c.smology is based on reinterp.etation of the energy–momentum tensor in Einstein's field equations. This c.eation c.rresp.nds to an irreversible energy flow from the gravitational field to the c.eated matter c.nstituents. The variable c.ap.ygin gas（Vc.） is also studied as a p.rtic.lar solution. We use the Markov c.ain Monte c.rlo method to c.nstrain the free p.rameters of three models, namely,Lambda-c.ld-Dark matter（Λc.M）, VGc. and Vc. models with and without matter c.eation from the latest observational data from baryon ac.ustic.osc.llations, c.smic.c.ronometer, typ. Ia sup.rnovae（p.ntheon） inc.uding gamma-ray bursts, quasars and the loc.l measurement of H0from R21 data. Two different c.mbinations of dataset p.ovide a fairly tight c.nstraint on the p.rameters of the Λc.M, VGc. and Vc. models. The p.esent values of various c.smologic.l p.rameters are obtained, whic. are very c.ose to the Λc.M model. Furthermore, we p.rform stability analysis, Bayesian evidenc. analysis and information c.iteria analysis for these models through studying the sound sp.ed, Bayes fac.or, and Akaike information c.iteria（AIc. and Bayesian information c.iteria（BIc. selec.ion c.iteria. The values of sound sp.ed for VGc. and Vc. models shows that both the models are stable. Ac.ording to AIc. it is observed that VGc. and Vc. models with matter c.eation are sup.orted c.nsiderably less by c.rrent observations,while BIc.shows that these models are not favoured by observational data.
