10Soil Bunds Effect on Soil Properties under Different Topographies of the Southwest Ethiopia显示文摘Soil erosion is a major environmental problem affecting development endeavor.Physical soil and water conservation(SWC)measures such as soil bunds are implemented to mitigate soil erosion.However,information on the effects of soil bunds on soil fertility is limited.This study was aimed to evaluate soil quality in fields with soil bunds and with no soil bunds in steep,middle and lower sloping cultivated lands as well as spatial variation of soil properties in between bunds in southwest Ethiopia.About 7-15 years old bunds and nearby cultivated fields lacking bunds were assessed.From 0 cm-20 cm soil depth,a 36 soil samples were collected.Soil texture,soil organic carbon(SOC),total nitrogen(N_(tot))and exchangeable potassium(K_(exch))were analyzed.Soil bunds showed significantly(p<0.0.5)greater clay but less sand than adjacent no-bund fields.In steep,middle,and lower slopes,concentrations of SOC and Kexch were greater in fields with soil bunds than without.Lower slope fields showed greater clay,SOC and nutrients than steep slopes.In between soil bunds,soil was more fertile at above bunds than below the bunds.In Fanta watershed,soil bunds are vital conservation measure to retain soil fertility on cultivated mountainous area.Wondimu Bekele Goba Alemayehu Muluneh Kebede Wolka 2022Journal of Environmental & Earth Sciences2022,4,1:0
11支管或毛管水头损失简化计算方法显示文摘前言支管或滴灌毛管的水头损失是灌溉系统优化设计的重要因素。最近,Warick和Yitayew(1987.1989)提出了描述典型支管问题非线性微分方程的解析解,得到相对流量和长度的关系,同时可以用这个解得到沿支管总水头的分布。Muluneh Yitayew 郑耀泉 1991喷灌技术1991,,3:0
12滴灌支(毛)管水头损失的简化近似计算法显示文摘一、引言 支(毛)管中的水头损失是有压灌溉系统优化设计的一个重要依据。近年来,Warrick和Yitayew(1987年,1988年)提出了描述支管水力学典型问题的非线性微分方程的分析解。用这种解法可得出流量比和长度比之间的关系,用来得出支管沿程水头的分布,也可应用于滴灌系统的设计(Yitayew和Warrick,1988年)。Muluneh Yitayew 杨应玖 胡竹君 1990灌溉排水1990,9,3:0
13红黄蓝赋格显示文摘年少时,我们背上行囊决定远走他乡的那一刻,纵然诸般留恋,也被压抑在内心对外面世界的憧憬之下。成年后,经过多年的跌跌撞撞,回望年少时想要远离的故乡,才发现,原来那个地方,才是我们心安的终点。吴启军 2021优雅2021,,8:0
14在间歇供水情况下土壤性质的变化显示文摘土壤性质不断变化是与周围环境相互作用的结果。土壤动力学中一个重要的因素是水。土壤的饱和减低土壤颗粒间的表面压力,且使土壤颗粒在重力作用下移动。按照Ghavami等的意见(1974),灌溉期饱和度增加,出现更大的固结和颗粒初始分离影响了最终的密度。浸润对土壤稳定性的影响受浸润前土壤含水量的影响(Panabokket和Qurik 1956)。Kemper和Rosenau(1984)指出,一般情况下,当浸润前的初始含水量较低时,Zohrab A.Samani Muluneh Yitayew 郭西万 1992灌溉排水1992,11,2:0
15环锭纺聚醚酯弹性纱的制备及其性能研究显示文摘采用传统环锭纺工艺,将聚醚酯(PEE)和聚对苯二甲酸丁二酯(PBT)共混体弹性短纤维纺制成弹性纱,研究弹性纤维纺纱工艺的原理和参数的选择,分析弹性短纤维和弹性纱的应力-应变行为及其弹性回复性,按照高柳素夫的方式给出了PEE-PBT共混体弹性的力学模型,可以解释制得纤维和纱线的高弹性。实验表明:由该聚醚酯共混体短纤维制造的弹性纱,在定伸长15%时,弹性回复率仍大于95%;而对该弹性纱循环拉伸后的弹性回复测试表明:在6次循环拉伸20%后的弹性回复率仍达到了90%,采用弹性短纤维可以成功纺制弹性纱。刘晓东 MULUNEH Bekele Haile 李瑞霞 常军 李延刚 吴大诚 2019毛纺科技2019,47,12:0
16Wild foods(plants and animals)in the green famine belt of Ethiopia:Do they contribute to household resilience to seasonal food insecurity?显示文摘Background:The role of wild foods in combating problems of food shortage is paramount.However,existing approaches to combat food insecurity shock have generally focused on reducing vulnerability via increasing productivity of domesticated foods.In contrast,approaches that enhance resilience mainly through wild food sources have been less focused.This study examined the contribution of wild foods to household resilience to food insecurity in the green famine belt of Ethiopia.Methods:A cross-sectional survey of 220 households was conducted using a structured questionnaire,key informant interviews,and semi-participant observations.Factor analysis was run using SPSS to analyze data.Correlation analysis was used to examine the direction and strength of association between wild foods and the income and food access(IFA),a latent proxy indicator of resilience.Cross-tabulation was also run to determine the proportion of households in each ethno-culture group under each resilience category.Results:The mean amount of wild foods obtained by households was 156.61 kg per household per annum.This was about 5%and 9%of,gross and,net food available from all sources respectively.Wild foods contributed well to household resilience as the factor loading(Factor2=0.467) was large enough and were significantly correlated with IFA(r=0.174).Wild vegetables were the most collected and consumed type of wild foods constituting 52.4%of total amount of wild foods.The total amount of wild foods was smaller than that of domesticated sources of food.The majority of households(38.6%) reported 'reduced source of wild foods' as a reason for this.Smaller proportion of the indigenous(11.2%) than the non-indigenous(34.1%) ethno-culture group reported one or more reasons for their lower level of dependence on wild foods.Conclusion:From the study we concluded that wild foods had important contribution to households' resilience to food shortages and are likely to continue to contribute in the future,this being more to indigenous than non-indigenous ethno-culture group.Therefore,a resilience building policy that incorporates wild foods should be adopted,and research that aims at exploring their current status and future prospect are urgently required.daie ferede guyu wolde-tsadik muluneh 2016Forest Ecosystems2016,3,1:0
