Ign.mbrites have been.widely used as buildin. materials in.man. historical an. touristic structures in.the Kayseri region.of.Türkiye. Their diverse colours an. textures make them a popular choice f.r modern.con.truction.as well. However, ign.mbrites are particularly vuln.rable to atmospheric con.ition., such as f.eeze-thaw cycles, due to their high porosity, which is a result of.their f.rmation.process. When.water en.ers the pores of.the ign.mbrites, it can.f.eeze durin. cold weather. As the water f.eezes an. expan.s, it gen.rates in.ern.l stress within.the ston., causin. micro-cracks to develop. Over time, repeated f.eeze-thaw (f.T) cycles lead to the growth of.these micro-cracks in.o larger cracks, compromisin. the structural in.egrity of.the ign.mbrites an. even.ually makin. them un.uitable f.r use as buildin. materials. The determin.tion.of.the lon.-term f.T perf.rman.e of.ign.mbrites can.be established af.er lon. f.T experimen.al processes. Determin.n. the lon.-term f.T perf.rman.e of.ign.mbrites typically requires exten.ive experimen.al testin. over prolon.ed f.eeze-thaw cycles. To streamlin. this process, developin. accurate predictive equation. becomes crucial. In.this study, such equation. were f.rmulated usin. classical regression.an.lyses an. artif.cial n.ural n.tworks (An.) based on.data obtain.d f.om these experimen.s, allowin. f.r the prediction.of.the f.T perf.rman.e of.ign.mbrites an. other similar buildin. ston.s without the n.ed f.r len.thy testin.. In.this study, un.axial compressive stren.th, ultrason.c propagation.velocity, apparen. porosity an. mass loss of.ign.mbrites af.er lon.-term f.T were determin.d. f.llowin. the f.T cycles, the disin.egration.rate was evaluated usin. decay f.n.tion.approaches, while un.axial compressive stren.th (UCS) values were predicted with min.mal in.ut parameters through both regression.an.

In.roduction. f.males with sickle cell disease (SCD), despite havin. a delayed pubertal developmen., are subject to man. worries relatin. to their abilities to con.eive, their capacity to main.ain.a matern.f.tal-risk-f.ee pregn.n.y till term an. give birth to healthy children.without sickle cell disease. Kn.win. that un.lan.ed pregn.n.ies are more likely to in.rease matern.f.tal morbidity an. mortality, we sought out to explore the pregn.n.y pref.ren.es in.f.male patien.s with sickle cell disease to promote healthy con.eption.an. childbirth in.this vuln.rable population. Methodology: We con.ucted a cross-section.l study in.olvin. f.male patien.s of.child-bearin. age with sickle cell disease f.llowed at Laquin.in.e Hospital Douala or who were members of.a local sickle cell association. Pregn.n.y pref.ren.es were determin.d usin. the Desire to Avoid Pregn.n.y (DAP) scale. f.ctors associated with pregn.n.y pref.ren.es were determin.d usin. multivariable lin.ar regression.model. Threshold f.r sign.f.can.e was set at p Results: Seven.y-seven.patien.s were in.luded with a mean.age of.24.71 ± 5.53 years. f.rty patien.s (51.95%) had on. sexual partn.r an. thirteen.women.(32.5%) used con.raceptive methods. Most patien.s (46.0%) respon.ed “Stron.ly Agree” or “Agree” to the statemen. “it would be a good thin. f.r me if.I became pregn.n. in.the n.xt 3 mon.hs”. The mean.DAP score was 1.63 ± 0.91 [1.28 ± 0.82 in.those who had a sexual partn.r an. 1.99 ± 0.86 in.those who had n. sexual partn.r]. f.ctors that were positively associated with DAP score were studen.s (b = 0.32, 95% CI [0.21, 0.95], p = 0.003), mon.hly in.ome ≥ 100,000 f.f.

This is especially true f.r patien.s who are n.t studen.s, have a partn.r an. have a low mon.hly in.ome.
