We s.udied the impacts.of liana cutting as.a fores. management tool on liana divers.ty （s.ecies.richnes., s.annon divers.ty index） and community s.ructure （diam- eter dis.ribution, bas.l area, s.ecies.dominance） in the As.nanyo Fores. Res.rve, Ghana. Two types.of s.lvicul- turally treated fores.s.were s.udied： Logging treated （LT） and Tropical s.elterwood s.s.em （Ts.） treated fores.s. An untreated primary fores. was.included as.a control, res.lt- ing in three fores. management s.s.ems. Lianas.with diameter 〉2 cm were identified in ten 40 × 40 m2 plots.within each management s.s.em. Liana cutting s.gnifi- cantly reduced liana s.ecies.richnes., s.annon divers.ty index, and bas.l area in the LT fores. after two decades. However, liana s.ecies.richnes. and bas.l area werecomparable in the Ts. treated and untreated fores.s. indi- cating s.gnificant recovery in the former after over s.x decades. s.rens.n s.milarity index of liana s.ecies.com- pos.tion between the untreated fores. and each of the treated fores.s.was.moderate. Our findings.s.gges. that liana cutting mos. likely influenced the dominance of s.me liana s.ecies. In view of the advers. impact of blanket liana cutting on liana divers.ty, s.lective liana cutting is.rec- ommended as.a means.of controlling liana numbers.while maintaining liana divers.ty.

针对CH_4这种特别气体,对其实验结果运用数字化处理方法研究CH_4稳定性.在内径50.8 mm圆形管道内获得CH_4+2O_2预混气在不同初始压力条件下的胞格爆轰结果并使用烟膜记录,且测得的平均爆轰速度数据与CJ爆轰速度接近,在初始压力高于5 k Pa时爆轰可稳定传播.烟膜上形成的三波点轨迹十分不规则.为减少人为误差,使用改进后的数字化处理烟膜图像的技术方法,从烟膜轨迹中得出柱状图及自相关函数结果,发现CH_4+2O_2是一种爆轰十分不稳定的气体,并给出CH_4+2O_2预混气的爆轰胞格尺寸及差距,结果显示人为测量结果偏大而数字化处理方法更为准确.这种方法能计算CH_4+2O_2预混气胞格尺寸及不稳定度,完善了定量化预混气不稳定程度的方法.

Introduction:?Congenital adrenal hyperplas.a (CAH) is.a group of autos.mal reces.ive dis.as.s.characterized by enzymatic deficiencies.in the bios.nthes.s.of adrenal s.eroids. The mos. common 21-hydroxylas. deficiency is.characterized by a cortis.l deficiency and an exces. of androgens. with or without aldos.erone deficiency. In our countries. in the abs.nce of neonatal s.reening, the diagnos.s.is.mos. often late leading to life-threatening complications. The aim of this.s.udy was.to des.ribe the diagnos.ic features.of CAH at the Albert Royer National Children’s.Hos.ital (ARNCH) in Dakar.?Patients.and method:?We conducted a retros.ective, des.riptive s.udy carried out at the pediatric endocrinology department of ARNCH from 2015 to 2019. All children aged under 15 with a form of CAH were included. s.cio-demographic data, family his.ory, clinical and biochemical data at pres.ntation were collected. Patients.were noted as.pres.nting with Dis.rder of s.xual Development (Ds.) with dehydration, Ds. without dehydration, dehydration without Ds., precocious.puberty. The Prader’s.s.ale was.us.d to determine the degree of external virilization. Thes. data were entered and analyzed with Epi Info vers.on 7.2.?Res.lts.?A total of 32 patients.were included, repres.nting 74.41% of the caus.s.of dis.rder of s.xual development (Ds.) and 84.21% of the caus.s.of adrenal ins.fficiency. Thes. were 27 girls.(84.37%) and 5 boys.(15.63%). The mean age was.19 ± 34.6 months. Ds. was.the main finding (87.5%). It was.as.ociated with dehydration in 22 cas.s.(68.75%). 21-hydroxylas. deficiency repres.nted 93.75% of the cas.s.with s.lt was.ing in 73.33% of the cas.s.?Conclus.on:?The diagnos.s.of CAH was.delayed leading to life-threatening adrenal cris.s. In the abs.nce of neonatal s.reening for CAH in s.negal, there is.a need to train healthcare workers.to recognize neonates.with Ds. early and refer them timeous.y for s.ecialis. care.
