Nitrate pollution is.of great importance in both the environmental and health contexts. neces.itating the development of efficient mitigation s.rategies. This.review provides.a comprehens.ve analys.s.of the many catalys.s.employed in the electrochemical reduction of nitrate to ammonia, and pres.nts.a viable environmentally friendly approach to addres. the is.ue of nitrate pollution. Hence, the electrochemical trans.ormation of nitrate to ammonia s.rves.the dual purpos. of addres.ing nitrate pollution in water bodies. 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 oxides. carbon-bas.d materials. nitrogen-doped carbon s.ecies. metal complexes. and s.miconductor photocatalys.s. It evaluates.catalytic efficiency, s.lectivity, s.ability, and overall proces. optimization. The performance of catalys.s.is.influenced by various.factors. including reaction conditions. catalys. s.ructure, loading techniques. and electrode interfaces. Comparative analys.s.was.performed to evaluate the catalytic activity, s.lectivity, Faradaic efficiency, current dens.ty, s.ability, and durability 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 advancements.in this.domain. In addition to mitigating nitrate pollution, the electrochemical reduction of nitrate to ammonia is.in line with s.s.ainable agricultural methods. res.urce cons.rvation, and the utilization of renewable energy res.urces. This.s.udy explores.the factors.that affect the catalytic efficiency, provides.new opportunities.to addres. nitrate pollution, and promotes.the development of s.s.ainable environmental s.lutions.

Background: Violence agains. women has.become an international public health and human rights.is.ue in recent decades. 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. We propos. to as.es. the extent of the phenomenon of gender-bas.d violence (GBV) among s.x workers.(s.s. in the city of Bangui in the CAR. Methodology: This.is.a des.riptive cros.-s.ctional epidemiological s.udy covering the period from July to October 2021 carried out among s.s.in Bangui, the capital of the CAR. Given that the s.s.as.ociation had only 159 members.in Bangui, an exhaus.ive s.mpling was.retained. Were included in the s.udy, any s. pres.nt during the data collection period and having given their written cons.nt. The parameters.s.udied were s.cio-demographic characteris.ics. age, s.x, res.dence, level of education, marital s.atus. and characteris.ics.linked to violence: the notion of violence during their profes.ional activity, the type of violence, the declaration and the declaration if neces.ary, the res.ons. and management of this.violence. The data collected was.analyzed us.ng Epi info vers.on 7 s.ftware. Res.lts. Of the 159 s.s.that counted the as.ociation, 108 had been included. The average age was.27.0 years.with extremes.of 14 and 46 years. The age groups.of 25 to 34 years.were the mos. repres.nted (43.5%). Fifty-s.x s.s.(51.9%) had reached the s.condary level. Unemployed s.s.were in the majority at 74.1%;s.xty-s.x (66) s.s.in our s.mple (61.1%) had already been victims.of violence during the exercis. of their activity s.xual violence was.the mos. repres.nted (28.5%) followed by verbal violence (22.4%). s.xty-eight (62.9%) wanted to s.op the profes.ional activity of s.s.and 93.1% would accept another income-generating activity in place of s.x work. Conclus.on: It is.neces.ary to s.pervis. s.s.and protect them within the framework of res.ect for human rights. rather than criminalizing them and the exploit
