    Assessment and Enhancement of HMIS Implementation Strategy in Oromiya Region at Chancho Health Center.
    (Addis Ababa University, 2015-05-06) Negash, Tadele; Beshah, Tibebe(Dr)
    Background: - HMIS is an organized system of record keeping, reporting, processing analysis, use and feedback of information. Effective health management information system (HMIS) is essential for setting priority for community based problems, for allocation of budget and human resource and decision making in general to managers and stakeholders. Facilitate informed Local decision making it is necessary to implement health management information system to timely and accurately provide at the level of health facility. Objective: - The purpose of this study was to assess the weakness and strength of the existing HMIS and implementation at chancho health center. Methodology: - A facility based cross sectional Descriptive study was conducted in Chancho Health Center from February to April, 2015. Both qualitative and quantitative research methods were used. Data were collected through open ended questions of self administered filled by 50 health professionals who were volunteer at the time of data collection. Qualitative data which is Observations and in depth interview was conducted with head of health center and HMIS focal person, for qualitative analysis of certain document. SPSS version 20 software was used to analyze quantitative data. Results: - The finding of the study was presented in table. The quantitative results on each outcome measures use in assessment are reported and explored by qualitative methodology. .Most of the respondents were health professionals with qualification out of the questioned 50 staffs 32 (64%) Diploma and 18 (36%) were Degree. 90% of the respondent reported that 43 (86%) of the respondent said, there is no trained staffs on basic computer literacy and manual reporting. lack of coordination mechanism has also played its part for this challenge. 39 (78%) of the respondents said that, there was no incentive for information use and it shows also that 41 (82%) of the respondents said that, there is no motivation mechanism to improve information culture. Conclusion and recommendations: I, conclude That There is no necessary input to HMIS like budget, training and coordination mechanism in the facility. It was also recommended that HMIS implementation program in the facility should have ownership and it is important to identify the X capacity requirement of the HMIS unit at health center level and the health professional and health managers at health center level need to be motivated and encouraged in order to make them committed and accountable to their work.

    Holographic Applicatons
    (Addis Ababa University, 2010-07) Negash, Tadele
    Holography is a technique of recording the whole information of an object by using a reference beam which is combined with the light from the object (an object or scene beam). If these two beams are coherent, optical interference between the reference beam and the object beam, due to the superposition of the light waves, produces a series of intensity fringes that can be recorded on standard photographic film. The fringes form diffraction grating called hologram. When viewed from different angles or changing orientation it seems the object is still present and the image appears three dimensional. It is a lens less image recording technique. Hologram and holographic products are used in various products like currency, credit cards, etc. Also it is applied to combat counterfeit, for security purpose, for attractive product packaging and so on

    Refining of Used Motor Oil Using Solvent Extraction
    (Addis Ababa University, 2016-07) Negash, Tadele; Yimam, Abubeker (PhD)
    Used lubricating motor oil is a high pollutant material that requires responsible management. It may cause damage to the environment when dumped into the ground or into water streams including sewers. This may result in groundwater and soil contamination. Recycling of such contaminated materials will be beneficial in reducing lubricating motor oil costs. In addition, it will have a significant positive impact on the environment. Used oil can be refined to yield base oils that are blended into lubricating products, thus reducing the consumption of virgin oils. Refining restores the physical and chemical properties of lubricating oil so that it can go back to its original and intended use. This thesis work investigates refining of used lubricating motor oil using solvent extraction method. The laboratory experiment was based on a full factorial design and two categorical factors with two levels were nominated which were solvent to used oil ratio (4:1&6:1) and solvent type (2-Propanol and n-Butanol). First used lubricating motor oil, of two varieties, namely TOTAL Rubia and TOTAL Quartz was collected from TOTAL Ethiopia oil company gas stations and characterized for important properties and contaminates. Then by applying appropriate treatment, i.e. pretreating, dehydration, vacuum distillation, solvent extraction and distillation for solvent recovery, the base oil was obtained. The refined base oil was then characterized and compared with the used and virgin oil. The type of solvent used and the mixing ratio applied for different runs has shown significant effects on the yield of recovered oil. 2-Propanol solvent with mixing ratio of 6:1 gave the best result. A Maximum yield of 72% was obtained for Rubia Tir 7400 using 2-Propanol solvent and mixing ratio of 6:1, whereas minimum recovery yield of 55% was obtained using n-Butanol and 4:1 mixing ratio. For Quartz 20W-50 a maximum yield of 73.4 was obtained using 2-Propanol solvent and mixing ratio of 6:1 whereas minimum recovery yield of 50% was obtained using n-Butanol and 4:1 mixing ratio. The metal contaminants and chlorine are considerably reduced in the base oils for both lubricants. So it can be concluded that used lubricating motor oil can be refined using solvent extraction method and reduces environmental contaminations and decreases foreign currency
