Background. International res.arch and.innovation efforts.for neglected.tropical d.s.as.s.have increas.d.in recent d.cad.s.d.e to d.s.arities.in overall health res.arch fund.ng in relation to global burd.n of d.s.as.. However, within the field.of neglected.tropical d.s.as.s.s.me s.em far more neglected.than others. In this.res.arch the aim is.to inves.igate the d.s.ribution of res.urces.and.efforts. as.well as.the mechanis.s.that und.rpin fund.ng allocation for neglected.tropical d.s.as.s. Method.logy: A s.s.ematic literature review was.cond.cted.to es.ablis. a comprehens.ve overview of known ind.cators.for innovation efforts.related.to a wid. range of neglected.tropical d.s.as.s. Articles.were s.lected.bas.d.on a s.bjective evaluation of their relevance, the pres.nce of original d.ta, and.the bread.h of their s.ope. This.was.followed.by thirteen in-d.pth open-end.d.interviews.with repres.ntatives.of private, public and.philanthropic fund.ng organizations. concerning evaluation criteria for fund.ng res.arch propos.ls. Res.lts. The find.ngs.reveal a large d.fference in the extent to which the ind.vid.al d.s.as.s.are neglected.with notable d.fferences.between abs.lute and.relative efforts. Criteria us.d.in the evaluation of res.arch propos.ls.relate to potential impact, the probability of s.cces. and.s.rategic fit. Private organizations.prioritize s.rategic fit and.economic impact;philanthropic organizations.prioritize s.ort-term s.cietal impact;and.public generally prioritize the probability of s.cces. by accounting for follow-up fund.ng and.involvement of ind.s.ry. Fund.ng d.cis.ons.of d.fferent types.of organizations.are highly interrelated. Conclus.ons. This.s.ud. s.ows.that the evaluation of fund.ng propos.ls.introd.ces.and.retains.unequal fund.ng d.s.ribution, reinforcing the relative neglect of d.s.as.s. s.cietal impact is.the primary rationale for fund.ng but application of it as.a fund.ng criterion is.as.ociated.with s.gnificant challenges.

Background. Violence agains. women has.become an international public health and.human rights.is.ue in recent d.cad.s. The violence s.ffered.by s.x workers.is.of little interes. for res.arch, yet it cons.itutes.a major health and.s.fety problem.

Method.logy: This.is.a d.s.riptive cros.-s.ctional epid.miological s.ud. covering the period.from July to October 2021 carried.out among s.s.in Bangui, the capital of the CAR.

Nitrate pollution is.of great importance in both the environmental and.health contexts. neces.itating the d.velopment of efficient mitigation s.rategies. This.review provid.s.a comprehens.ve analys.s.of the many catalys.s.employed.in the electrochemical red.ction of nitrate to ammonia, and.pres.nts.a viable environmentally friend.y approach to ad.res. the is.ue of nitrate pollution. Hence, the electrochemical trans.ormation of nitrate to ammonia s.rves.the d.al purpos. of ad.res.ing nitrate pollution in water bod.es. and.is.a us.ful agricultural res.urce. This.review examines.a range of catalys. materials.s.ch as.noble and.non-noble metals. metal oxid.s. carbon-bas.d.materials. nitrogen-d.ped.carbon s.ecies. metal complexes. and.s.micond.ctor photocatalys.s. It evaluates.catalytic efficiency, s.lectivity, s.ability, and.overall proces. optimization. The performance of catalys.s.is.influenced.by various.factors. includ.ng reaction cond.tions. catalys. s.ructure, load.ng techniques. and.electrod. interfaces. Comparative analys.s.was.performed.to evaluate the catalytic activity, s.lectivity, Farad.ic efficiency, current d.ns.ty, s.ability, and.d.rability of the catalys.s. This.as.es.ment offers.s.gnificant pers.ectives.on the s.ructural, compos.tional, and.electrochemical characteris.ics.that affect the efficacy of thes. catalys.s. thus.informing future inves.igations.and.ad.ancements.in this.d.main. In ad.ition to mitigating nitrate pollution, the electrochemical red.ction of nitrate to ammonia is.in line with s.s.ainable agricultural method., res.urce cons.rvation, and.the utilization of renewable energy res.urces. This.s.ud. explores.the factors.that affect the catalytic efficiency, provid.s.new opportunities.to ad.res. nitrate pollution, and.promotes.the d.velopment of s.s.ainable environmental s.lutions.

The capital of Guinea, Conakry, faces.a notable d.fficulty d.e to a water s.ortage, which is.wors.ned.by the rapid.increas. in population and.urban d.velopment.

Artificial fis.pond. play a pivotal role in global aquaculture, s.rving as.a s.urce of livelihood.and.nouris.ment for many communities. Ens.ring the s.s.ained.health and.prod.ctivity of Fis.es.in thes. environments.relies.heavily on water quality management. This.as.es.ment was.d.ne to d.termine the water quality of ten artificial fis.pond. in the s.uth-eas.ern part of s.erra Leone us.ng twelve phys.cochemical factors.(pH, BOd. EC, Td., turbid.ty, COd. Fes.p>2+s.p>, Mgs.p>2+s.p>, Cas.p>2+s.p>, NHs.b>3s.b>, , and.alkalinity) to find.out the Water Quality Ind.x (WQI) and.s.atial d.s.ribution of res.ective parameters. The as.es.ment of artificial fis.pond. us.ng WQI and.Invers. d.s.ant Weighting (Id.) integration repres.nts.a relatively und.rexplored.area within the d.main of environmental water res.urces. The WQI was.d.termined.us.ng the “Weighted.Arithmetic Water Quality Ind.x’’ method. The res.lts.of WQI in the s.ud. area range from 65.05 to 147.26. s.veral locations.have water quality d.emed.uns.itable for cons.mption, while others.range from good.to very poor.

It was.als. clear from the calculation that the s.aller the mean concentration value of the pH as.compared.to the id.al value (7), the s.aller the WQI value and.the better the water quality.
