Rocket launching site selection in Ethiopia using Weight Decision Matrix analysis

The term rocket launch site is used in any facility from which rockets are launched and contains one or more launch pads. Development in Space Science and Technology is a critical issue for any country it is a guarantee for security and sustainable development. Research is taking place on sounding rockets, micro, nano and can-type satellite technologies that require huge foreign currencies to launch overseas. The purpose of this research paper is to determine specific rocket launching sites in Ethiopia. The weighted decision matrix is used as a tool to analyze valued criteria and to rank the alternatives. In the first phase, the whole regions are analyzed and three regions are selected, which are located at 6o Latitude North and 41o Longitude East. Similarly, in the second phase, the weighted decision matrix tool is applied to three selected regions at Woreda (Districts) and Kebele (Cluster) level. The selected sites are from Somali Warder Zone, identified as Boh 1 and 2 with a value of 231. In Oromia identified as Borena-1 with a value of 195 and the rest with lower value are rejected. A site map is prepared for the best sites selected. A spaceport is an important source of income for launching companies. There are opportunities of leasing to international launching operators for launching rockets and research rockets. It can also benefit African countries for rocket research related issues since no country in east Africa has their own functional launch site

Effectiveness of Bubble Continuous Positive Airway Pressure (BCPAP) for Treatment of Children Aged 1–59 Months with Severe Pneumonia and Hypoxemia in Ethiopia: A <i>Pragmatic Cluster Randomized Controlled Clinical Trial</i>

Despite the beneficial effect of bubble continuous positive airway pressure (BCPAP) oxygen therapy for children with severe pneumonia under the supervision of physicians that has been shown in different studies, effectiveness trials in developing country settings where low-flow oxygen therapy is the standard of care are still needed. Thus, the aim of this study is to assess the effectiveness of bubble CPAP oxygen therapy compared to the WHO standard low-flow oxygen therapy among children hospitalized with severe pneumonia and hypoxemia in Ethiopia. This is a cluster randomized controlled trial where six district hospitals are randomized to BCPAP and six to standard WHO low-flow oxygen therapy. The total sample size is 620 per arm. Currently, recruitment of the patients is still ongoing where the management and follow-up of the enrolled patients are performed by general physicians and nurses under the supervision of pediatricians. The primary outcome is treatment failure and main secondary outcome is death. We anticipate to complete enrollment by September 2022 and data analysis followed by manuscript writing by December 2022. Findings will also be disseminated in December 2022. Our study will provide data on the effectiveness of BCPAP in treating childhood severe pneumonia and hypoxemia in a real-world setting
