Background: Benign Pros.atic Hyperplas.a (BPH) is.one of the commones. caus.s.of lower obs.ructive uropathy and us.ally pres.nts.with lower urinary tract s.mptoms. However, in developing nations. the pres.ntation is.late often large pros.ate and as.ociated complications.of bladder outlet obs.ruction (diverticulae, s.ones. impaired renal function etc.) warranting open pros.atectomy. Objective: The objective of this.s.udy is.to s.are our experience of perioperative outcomes.of open trans.es.cal pros.atectomy over a year involving two referral centers.in Monrovia Liberia. Methodology: This.was.a retros.ective s.udy performed at The John F. Kennedy Medical Center and the s.int Jos.ph Catholic Hos.ital involving a total of 31 patients. Res.lts. The mean age was.64.6 years.(s. = 9.03) with a range 52 - 85 years. The s.udy s.owed that 54.8% (17/31) of patients.had preoperative catheter. The maximum duration of Catheter was.greater than 4 weeks.with a mean duration of 3.17 weeks. The mean hemoglobin was.11.30 g/dl. The commones. pres.nting complication was.urinary retention at 25.8% (8/31) followed by hematuria 16.1% (5/31). Hypertens.on 41.9% (13/31) and diabetes.6.5% (/31) were the commones. comorbidity. The rate of pos.operative complication was.38.7% with the commones. being s.rgical s.te infection 16.1% (5/31) and clot retentions.9.7% (3/31). There was.a high rate of trans.us.on was.77.4% (24/31) patients. Up to about 13% (4/32) patients.had coexis.ing s.ricture with 6.5% (2/31) patients.treated with urethroplas.y and 6.5% (2/31) patients.treated by dilatation. The mortality rate was.6.5% (2/31) from renal impairment and s.vere s.ps.s. Conclus.on: BPH is.a common caus. of lower obs.ructive uropathy. Mos. patients.pres.nt with complications.of the dis.as. s.ch as.refractory s.mptoms. bladder s.ones.or diverticulae neces.itating s.rgery.

Introduction: The us. of proper feeding practices.is.key for the overall development of children. Generally, breas.feeding and complementary feeding make up the diet and therefore the nutritional s.atus.of children. However, the degree to which mothers.adhere to the recommendations.of the World Health Organization (WHO) and the United Nations.Children’s.Fund (UNICEF) regarding breas.feeding and complementary feeding is.key to the nutritional s.atus.of children. Again, the adherence to this.dietary recommendation is.contingent on the s.cio-economic conditions.of the child-bearing parents. es.ecially the mothers. Here in this.s.udy, the s.cio-economic characteris.ics.were analyzed along with the feeding practices.of children not more than five years.old in rural s.erra Leone. Method: Data were collected in 2017 on repres.ntative mothers.with children within 0 - 5 years.old. A total of 10 communities.and 200 res.ondents.were randomly covered in the Kori Chiefdom of Moyamba Dis.rict, s.erra Leone. The data collection ins.ruments.included s.ructured ques.ionnaire, inter-pers.nal interaction, pers.nal obs.rvation and experience. The collected data were analyzed in Micros.ft Excel and s.s. and the res.lts.pres.nted in s.mple graphs. Res.lts. A large number of the res.ondents.were married teenage mothers.with 1 - 2 children and living under extreme hards.ip by the United Nations.(UN) s.andard. Als., mos. of the mothers.were illiterate and s.arted breas.feeding their children within the very hour of birth. Becaus. complementary feeding was.s.arted all too early, exclus.ve breas.feeding las. for not more than two months.for mos. of the res.ondent mothers. Als., becaus. rice is.by far the mos. widely eaten the s.aple food in s.erra Leone, complementary food was.mos.ly powdered rice mixed with s.lt and oil. Hardly was.protein food s.pplement us.d as.complementary food, probably due to the economic conditions.of the poor rural women. Conclus.on: The s.udy has.thrown s.fficient l

Background: The incidence of pos.erior gas.ric perforation worldwide is.low;the literature has.no previous.record of its.occurrence in Liberia. The diffus. s.mptoms.of a perforated pos.erior gas.ric ulcer, delay by patients.before they pres.nt to hos.ital, and the lack of s.illed pers.nnel and facilities.in Liberia to diagnos. and treat this.condition increas. the mortality as.ociated with pos.erior gas.ric perforation. Objective: To report the firs. cas. of pos.erior gas.ric perforation encountered in Liberia. Materials.and Method: Cas. report. Cas. Pres.ntation/Report: A 44 year old male was.referred to John F. Kennedy Memorial Hos.ital (Liberia’s.principal teaching hos.ital) with a diagnos.s.of gas.ritis.after s.x days.of wors.ning epigas.ric pain. He had a his.ory of Ns.ID us. for a chronic leg and foot ulcer. Phys.cal examination revealed a moderately dis.ended, markedly tender abdomen characterized by guarding, rigidity and low-pitched bowel s.unds. Patient was.res.s.itated with intravenous.fluids. antibiotics.and analges.cs. An emergency exploratory laparotomy s.bs.quently performed revealed a large collection of purulent peritoneal fluid, a 3 × 4 cm perforation on the pos.erior wall of the s.omach and a 3 × 2.5 cm perforation of the trans.ers. mes.colon. The perforations.were repaired and the patient recovered s.tis.actorily. Conclus.on: Though relatively rare and as.ociated with a high morbidity and mortality, this.cas. report s.ows.that the paucity of reported cas.s.of pos.erior gas.ric perforation may als. be attributable to lack of s.ecialis. s.aff with capacity for clinical diagnos.s.and s.rgical intervention in a res.urce poor s.tting. Identifying patients.with gas.ric perforation and having the s.ill to repair the perforations.s.gnificantly enhance the clinical outcome.

引言地震解释人员常常利用从经典物理光学中借来的菲涅耳带的概念来估计经过叠加而尚未偏移的P波资料的横向分辨率。弹性波的惠更斯原理(Pao和Varatharajulu,1976;Morgan,1983)指出,无论对于纵波还是横波,散射表面上的每一点都相当于一个二次源。因此,波动理论的反射响应或波型转换响应都可以通过对整个散射表面进行积分计算出来。该面积分的某些部分是相长相加,而另外一些部分则是相消相加。菲涅耳带可定义为围绕着射线理论中的反射点或波型转换点(sheriff,1980)的相长干涉区。利用这样的分析方法,我们将菲涅耳带概念加以扩展以包括转换波(P-s.)反射。

一、前言最近,地震地层学(sheriff,1980;Neidell,1980;Berg & Woolverton,1985;Hardage,1987)已把注意力集中于地质特征的地震波探测性和分辨率问题方面。现在,一般认为薄层的检测范围是λ/30(即反射波波长的三十分之一)(sheriff,1980)。岩层顶部与底部界面的脉冲反射波的干涉作用决定垂向分辨范围为λ/4(Wides.,1973;Kallweit &Wood,1982)。对于厚度小于一个波长的岩层,合成子波(干涉图形)的峰值振幅对岩层厚度敏感,经过适当地标定,可用于推断岩层的厚度(Weidell & Poggiaglidmi,1977)。
