Fertility Desire and Contraceptive Utilization among People Living With HIV/AIDS on ART in Hosanna Town, Southern Ethiopia

HIV positive individuals may or may not have intention to have children. They could also have different degrees of utilization and demand for contraception. The desire of HIV infected persons to have children in the future has implication for the transmission of HIV to sexual partners or newborns. The study was designed to assess the fertility desire and contraceptive utilization among PLWHAs on ART in Hossana town. institutional based cross sectional study supplemented by in-depth  interview was conducted from January to March 2010 on total sample of 321 who were on ART. Women 18-49 years and men 18-59 years were included. Data was entered by using EPI info 2000 then exported and  analyzed by SPSS 17.0. Total of 117 (36.45%) of respondents were   desiring children. Respondents with no children (AOR 60.89, 95% CI  8.02-462.05), those who intended to use family planning in the future (AOR 4.35, 95% CI 1.61-11.73) were more likely to desire children. 102(31.8%) were using family planning. Being married (AOR 7.83, 95% CI 1.08-56.79), having three or more children (AOR 4.54, 95% CI  1.12-18.48), and having knowledge on mother to child transmission (AOR 4.29, 95% CI 1.98-9.26) plan to have children in the future (AOR 0.29, 95% CI 0.1-0.82) were significantly associated with family planning. A highproportion of HIV positive individuals desired children. A better and   evidence based understanding of fertility intentions and demand for contraception was needed to promote and protect women and men living  with HIV/AIDs to make informed decisions about reproduction and to have access to appropriate sexual reproductive health services

Tick infestation of Borana cattle in the Borana Province of Ethiopia

A study was conducted to identify and determine burdens of ticks infesting Borana cattle in the Borana Province of Ethiopia. Rhipicephalus pulchellus, Rhipicephalus pravus, Rhipicephalus muhsamae, Rhipicephalus praetextatus, Rhipicephalus evertsi evertsi, Amblyomma gemma, Amblyomma variegatum, Amblyomma cohaerens, Amblyomma lepidum, Hyalomma truncatum, Hyalomma marginatum rufipes and Boophilus decoloratus were identified on the cattle. Their burdens ranged from 658-1554 with a mean of 1205 ticks per animal. Out of the total 6025 ticks collected, about 82% were R. pulchellus, followed by R. pravus (about 8%) and A. gemma (5%). The other nine species of ticks accounted for only 5% of the total burdens. It is suggested that a strategic tick control method, aimed mainly at reducing the R. pulchellus burdens, with the objective of allowing a reasonable number of ticks to remain on cattle for the maintenance of endemic stability to tick-borne diseases be instituted.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Experimental investigation of gas–oil–water phase flow in vertical pipes: influence of gas injection on the total pressure gradient

Experimental work has been conducted to study the infuence of gas injection on the phase inversion between oil and water fowing in a vertical pipe. A vertical transparent pipe test section line of 40 mm ID and 50 cm length was used. The test fuids used were synthetic oil and fltered tap water. Measurements were taken for mixture velocity, superfcial water velocity, superfcial gas velocity, and input superfcial oil velocity ranging from 0.4 to 3 m/s, 0.18 to 2 m/s, 0 to 0.9 m/s, and 0 to 1.1 m/s. Most of the experiments were conducted more than two times, and the reproducibility of the experiments was quite good. Special attention was given to the efect of oil and water concentration where phase inversion took place with and without gas injection. The results showed that the phase inversion point was close to water fraction of ~30%, for both water friction direction changes (from water to oil or from oil to water) and that the efective viscosity increases once the mixture velocity increases. On the other hand, the results with gas injection showed that gas injection had no efect on the oil or water concentration where phase inversion occurred. Furthermore, the study investigated the efect of gas–oil–water superfcial velocity on the total pressure gradient in the vertical pipe. It was found that the total pressure gradient was fast and increased at high superfcial gas velocity but was slow at low superfcial gas velocity. When the superfcial oil velocity increased, the total pressure gradient approached the pressure gradient of an oil–water two-phase fow. The obtained results were compared with few correlations found in the literature, and the comparison showed that the uncertainty of the fow pattern transition peak in this study is very lo

An overview of the development challenges and constraints of the Niger Basin and possible intervention strategies

The Niger River Basin covers 7.5% of the African continent, and is shared between nine riparian countries. The basin countries can be categorized into water resources producers, consumers, both producers and consumers, and minimum contributors and consumers. As in the case for most transboundary rivers, upstream and downstream conflicts emanating from the development and utilization of the Niger River are inevitable and are expected to be intense, particularly given the escalating demands for water from the many uses and users. The basin is divided into four major sections, namely Upper Niger, Inland Delta, Middle Niger, and Lower Niger. But these divisions, though useful, are too generic to provide a complete understanding of biophysical, hydrological and socioeconomic processes impinging on the basin’s water resources, and to provide intervention recommendations. On average, the basin’s population is two-thirds (64%) rural and a significant part of the northern zones of the basin is unpopulated. People in the basin are engaged in various livelihood strategies such as dry- and wet-season cropping systems, pastoral systems, crop-livestock systems, and fishing. The dry-season livelihood systems include fadama (lowland or inland valleys) farming, recession flood farming, agroforestry, irrigated rice farming and fishing. Wet-season livelihood systems center mostly on cereal cropping and transhumance. The major crops grown in the basin are yam, cassava, rice, groundnut, millet, sorghum, plantain, cocoa, maize, sugarcane, and cotton. Agriculture represents a large part of the gross domestic product (GDP) of the Niger River Basin with crop production alone contributing 25-35% of the basin’s GDP, while livestock and fishery contribute 10-15% and 1-4%, respectively. All countries of the Niger Basin suffer from chronic and acute poverty and are ranked ‘poor’ by most poverty indicators (Human Development Index [HDI]), child mortality, life expectancy, Social Vulnerability Index, etc.). Several structural (social and institutional) factors hold a large segment of the basin’s population in the throes of poverty. Niger Basin’s challenge is to break this vicious circle by using resources to generate sustainable growth that is favorable to the poor. Some of the prominent water-related challenges are degradation of land and water resources, climate change and variability, vulnerability to disasters, inefficiency and poor performance of agriculture (rain-fed and irrigation), competing demands between sectors and water users and inadequate investment in water infrastructure. At a wider level, inadequate public services, institutional and governance failure, high population growth and urbanization, poor macro-economic performance, and unemployment have also undermined the development of the basin. The severity of these challenges varies from location to location in the basin. The basin’s development goals and objectives originate as a response to the development challenges and are articulated in various policy documents such as the Niger Basin Shared Vision (NBA PADD), poverty reduction strategy papers, United Nations (UN) Millennium Development Goals (MDGs), and the New Partnership for Africa’s Development (NEPAD), specifically the pillars 1, 2, 3 and 4 of the Comprehensive Africa Agriculture Development Programme (CAADP). The goals of the basin countries are eradicating extreme poverty and hunger; achieving universal primary education; promoting gender equality and empowerment of women; reducing child mortality; improving maternal health; combating Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS), malaria and other diseases; ensuring environmental sustainability; and developing a global partnership for development. viii The specific development objectives of the basin countries are the following: • Increase income, generate jobs, improve living standards, and alleviate poverty, especially among the poorest section of the population while at the same time safeguarding the environment including the sustainable management of the Niger Basin water resources. • Improve access to health and education services, and increase life expectancy. • Achieve political stability, good governance and an appropriate institutional framework. • Improve the investment climate for private-sector development where infrastructure plays a decisive part. • Develop infrastructures and the productive sector to ensure better productivity of factors of production and economic growth. • Reduce food imports, boost agricultural exports through stabilization, intensification and expansion of agricultural production. To realize the basin’s development goals and objectives the following water-centered intervention clusters needed to be synergistically pursued. • Ensuring right to secure access to water for the poor. • Developing new infrastructure. • Improving access to agricultural water management innovations. • Strengthening Niger Basin’s water governance. • Upgrading rain-fed systems. • Reducing the vulnerability of poor people to climate shocks and other hazards. • Minimizing degradation of the terrestrial and aquatic ecosystems. • Diversifying livelihood strategies

Land, soil and water management

This chapter reviews relevant Vertisol properties, experimental results and the overall experience of the project on this subject. There are several types of drainage problems in Vertisols whose magnitude may vary from site to site. Drainage improvement is discussed in relation with camber beds, broadbeds and furrows, field depressions, perched watertable, open ditches, height of beds, soil erosion and supplemental irrigation. The need for water shed development projects is also examined

Distribution and importance of Ethiopian vertisols and location of study sites

This chapter describes the distribution, use and importance of Vertisols in Ethiopia and indicates the study sites of the Joint Vertisol Project. Land and soil features are examined with particular reference to parent materials and landscape features, soil characterisation (colour, texture and depth-to-root-restricting layer). Distribution of Vertisols along the 12 physiographic regions of Ethiopia is described, the major agro-ecological zones of Ethiopia is listed, and distribution of Vertisols and their associations in Ethiopia is shown. Also grain yields some food crops on Vertisols under traditional management in the central Ethiopian highlands and potential arable areas of Vertisols in the different thermal and growing period zones

Fasciolosis: Prevalence, financial losses due to liver condemnation and evaluation of a simple sedimentation diagnostic technique in cattle slaughtered at Hawassa Municipal abattoir, southern Ethiopia

This study was carried out from November 2007 to April 2008 to determine the prevalence of fasciolosis and costs incurred due to liver condemnation and evaluate the sensitivity of direct sedimentation method for diagnosis of fasciolosis in cattle slaughtered at Hawassa Municipal abattoir. A total of 3251 adult indigenous cattle were slaughtered at the abattoir during the study period, of which 931 animals (28.63%) were found to be positive for fasciolosis. There was a statistically significant (χ2 = 33.10; p = 0.004) variation in prevalence between the study months where the highest (35.6%) and lowest (21.03%) prevalence were recorded in February and April, respectively. Fasciola hepatica (58.9%) was the predominant fluke identified compared to F. gigantica (10.6%). Mixed infections by both species and unidentified immature flukes were detected in 14.7% and 15.8% of the affected livers, respectively. The mean fluke burden in the affected livers was 55 flukes per liver. As to the severity of infection, 36.63%, 52.31% and 11.06% were lightly, moderately and severely affected, respectively. Moderately affected livers showed the highest mean fluke count (69 ± 1.91) followed by severely (48 ± 1.71) and lightly affected ones (25 ± 1.75) signifying the presence of acquired resistance and local tissue reaction as chronicity of infection supervenes. Taking liver examination as gold standard for diagnosis of fasciolosis, the sensitivity of the direct sedimentation technique was found to be 67.13% and the specificity 100% with substantial agreement (k = 0.74) between the two methods. The financial loss due to liver condemnation was estimated to be 106,400 Ethiopian birr (8312.5 USD) per annum. In conclusion, the observation of such a level of infection in the dry season, high fluke pathogenicity and substantial financial loss associated with condemnation of infected livers warrants the institution of appropriate control measures.

Effects of lime and phosphorus rates on growth of hybrid Arabica coffee seedlings at Jimma, southwest Ethiopia

Open Access ArticleCoffee growing soil of southwestern region parts of Ethiopia are classified as Nitisols with having a low pH and highly deficient in phosphorus. A nursery experiment was conducted at Jimma Agricultural Research Center, southwestern Ethiopia to evaluate the effects of lime and phosphorus rates on coffee seedling growth under nursery conditions. The experiment was laid out in a randomized complete block design with 3 replications. The treatments were arranged in factorial combinations of five levels of lime (0, 5, 10, 15 and 20 g) and four levels of phosphorus (0, 400, 600 and 800 mg) 2.5 kg-1top soil. The statical data was analyzed through SAS software and treatment means were compared at 5% probability using Duncan Multiple Range Test. The results revealed that the interactions of lime and P rates significantly increased the growth of both non-destructive parameters (plant height, girth, number of nods, interned length, leaf number and leaf area) and Root growth parameters (taproot length, lateral root length, lateral root number, root volume, leaf stem and root fresh weight, of coffee seedlings. The maximum shoot and root extensions were obtained from the interaction of 10 g lime and 800 mg P rates 2.5 kg-1top soil. On the other hand, applications of P significantly (P≤ 0.01) affected soil and plant growth parameters. As P rate increased availability P boosted and plant growth were enhanced. Similarly, an application of lime significantly affected (P≤ 0.01) plant growth and enhance nutrient availability up to 10 g, though further applications adversely affect seedling growth and nutrient availability. Hence, combined application of 10 g lime and 800 mg P rate 2.5 kg-1top enhances the optimum growth of coffee seedlings under nursery conditions
