We explore the pa.a.eters tha. influence the dyna.ics of wa.er erosion. The method used is a. experimenta. la.ora.ory simula.ion, which consists of the qua.tita.ive eva.ua.ion of eroded ma.ses a. a.function of slope, soil cohesion a.d ra.nfa.l intensity. a.simula.or wa. designed to ha.e the a.ility to va.y the slope of the terra.n, a. well a. the ra.nfa.l intensity. The va.ia.ion of the soil cohesion is obta.ned by compa.ting the soil under different pressures using a.hydra.lic press a.socia.ed with the whole experimenta. device. The results obta.ned show tha. the device is a.good tool to simula.e in the la.ora.ory the beha.ior of different soil under the a.tion of ra.n;beca.se these results a.e in a.reement with existing models USLE, MUSLE a.d RUSLE [1] [2] [3] [4].

background: Infection with the new Coronavirus 2019 SARS-CoV-2, COVID-19, is a global pandemic that does not spare children. Pediatric forms of COVID-19 are increasingly described in the literature with less severe clinical forms and lower mortality as compared to adults. We do not have data on the epidemiologic characteristics of SARS-CoV-2 infection in children in sub-Saharan Africa where the pandemic is less severe. Aim: We present four cases of pediatric COVID-19 in Cameroun. Case Presentation: These cases of COVID-19 concern children aged 12 weeks to 13 years. We discuss the diagnostic difficulties and the issues of effective management in the context of a resource-constrained country. Conclusion: COVID-19 affects children in sub-Saharan Africa. There are different clinical presentations with favorable outcomes, but there is a need for greater vigilance in the pediatric population.a.>

Our study is being ca.ried out in the Wouri Estua.y more precisely in the Nylon a.ea. Doua.a. This a.ea.is influenced by a.unda.t ra.nfa.l which promotes the phenomenon of ra.n erosion. This erosion contributes to the degra.a.ion of structures a.d soils. To better understa.d a.d predict this phenomenon of ra.nfa.l erosion, we set out to esta.lish a.ma.hema.ica. model tha. ta.es into a.count precipita.ion a.d topogra.hy. To this end, the da.a.collected in the field a.d in the la.ora.ory ma.e it possible.

Next, we identified a.ma.hema.ica. model from cubic spline surfa.e interpola.ion. Fina.ly, we obta.ned the ma.hema.ica. model which ma.es it possible to eva.ua.e a.d predict the erosion potentia..

支气管肺发育不良在极不成熟早产儿中是一种重点关注的疾病.地塞米松通常应用于治疗支气管肺发育不良和预防慢性肺部疾病,它有助于减少对氧气的依赖以及早期拔管,尽管其治疗呼吸系统疾病的长期疗效文献很少记载,但最近研究结果显示预防性应用地塞米松能减少慢性肺部疾病的发生率.然而,这种治疗方法的一些副面效应也有报道,包括葡萄糖不耐受、院内感染危险性增加、胃十二指肠出血以及体重增长延迟的发生,其中一些并发症在生后早期应用地塞米松治疗的患儿中更常见.
