Agricultural lime value chain efficiency for reducing soil acidity in Ethiopia
No full textSoil acidity is challenging agricultural production in Ethiopia. Above 43% of the farmland is under soil acidity
problem and it leads to low crop yields and production losses. Ag-lime is widely considered as an effective
remedy for amending soil acidity. This study assesses the current structure of ag-lime value chain and its
functionality focusing on central parts of Ethiopia where lime is produced and channeled to acidity affected
areas. The study uses Ethiopia as a case study and applies qualitative methods such as key informant interviews and focus group discussions to collect data from different actors in the ag-lime value chain. Key findings indicate that both public and private ag-lime producing factories are operating below their capacity. Due to limited enabling environments, the engagement of private sector in ag-lime value chain is minimal. In addition, farmers have a good awareness of soil acidity problem on their farms, and its causes and mitigation strategies in all regions. However, the adoption of ag-lime by smallholders was minimal. Overall, the current structure of the aglime value chain appears fragmented and needs improvement. Addressing soil acidity challenge through efficient ag-lime value chain could narrow lime supply-demand mismatches and increase widespread adoption by farmers to enhance crop productivity and food security in acidity-prone areas of the country
Performance Measurement and Improvement for Ethiopian Tannery Industries: Case Study on Addis Ababa Tannery Share Company
No full textThe industrial strategic development plan of Ethiopia gives great emphasis to improve export-led
products to join the international market in a large scale. The strategy also promotes capital
saving and labor-intensive industrial development policy using coordinated approach (joint
forum) of supply chain management to encourage the production of value-added products. As a
predominantly agricultural economy with the largest cattle population in Africa, Ethiopia has a
strong base for semi-processed leather, finished leather and leather products. So Ethiopia’s
leather industry is in the forefront of the leather sector development within the Eastern and
Southern African region. The recent export development strategy introduced by the government
has give priority and incentive schemes for this sector. However, the challenge is how to make
best use of the country’s revealed comparative advantage to build a dynamic and competitive
sector that contributes to Ethiopia's economic growth.
Since tanning sub-sector has a great potential for rapid development of Ethiopian leather sector and
economic growth of the country, performance improvement of Ethiopian tannery industry needed.
Therefore, the aim of this thesis is to assess performance measurement and improvement
practices, determine key performance improvement areas, and make proper recommendation and
formulate performance measurement and improvement model for Ethiopian tannery industries
and case company.
This research paper reviews worldwide researches that related with performance measurement
and improvement. It has been conducted in a sample of eleven Ethiopian tannery industries and
case company by using a well structured survey questions, interviews, personal observation, and
secondary data collection. The results from this research assure that the major performance
problems of tannery industries are shortage of raw materials, low skill of workers, machinery
breakage, poor resource planning, poor customer and supplier relations, and poor performance
management. Depending upon the research findings, performance measurement and
improvement model with its implementation steps is recommended as a solution
Attention-Based Long Short-Term Memory Recurrent Neural Network for Capacity Degradation of Lithium-Ion Batteries
No full textMonitoring cycle life can provide a prediction of the remaining battery life. To improve the prediction accuracy of lithium-ion battery capacity degradation, we propose a hybrid long short-term memory recurrent neural network model with an attention mechanism. The hyper-parameters of the proposed model are also optimized by a differential evolution algorithm. Using public battery datasets, the proposed model is compared to some published models, and it gives better prediction performance in terms of mean absolute percentage error and root mean square error. In addition, the proposed model can achieve higher prediction accuracy of battery end of life

During pancreatitis, the activity of serum amylase and lipase is elevated three times above the upper limit of the normal range. This elevation was observed in both prediabetic and diabetic patients. Severe acute pancreatitis can result in acute kidney injury and other multi-organ dysfunction, which is one of the reasons for death.Objective: This study aimed to evaluate the elevation of serum amylase and lipase and their distribution at different stages of renal insufficiency among diabetic patients.Methods: This study included 286 diabetic patients (36 type 1 and 250 type 2), and data were collected from May 1 to June 30, 2019. The study design used was an institution-based cross-sectional study. A face-to-face interview was used to collect data, and serum creatinine, amylase, and lipase levels were measured using a chemistry analyzer. For data entry and statistical analysis, respectively, Epidata software version 3.02 and SPSS version 21 were used.Results: The mean serum amylase among diabetic patients suffering from G3b and G4 was 106.79 IU/L ± 118.18 IU/L and 104.85 ± 90.42 IU/L, respectively. Their mean serum lipase activity was 105.07 IU/L ± 127.54 IU/L and 106.98 IU/L ± 88.35 IU/L, respectively. Serum lipase activity was elevated above the normal range and three times above the upper limit of the normal range with a magnitude of 11.2% and 4.2%, respectively. Similarly, 9.1% and 0.7% of diabetic patients had increased serum amylase above the normal range and three-fold above the normal range, respectively.Conclusion: As glomerular filtration decreases, particularly in moderate-to-severe chronic kidney disease, serum amylase and lipase activity rise above the upper limit.Keywords: acute pancreatitis, chronic kidney disease, diabetes mellitus, serum amylase, serum lipas

Utilizations of Electro-coagulated Sludge from Wastewater Treatment Plant data as an Adsorbent for Direct Red 28 Dye removal
No full textElectro-coagulated, EC, sludge from the electrochemical processes of textile wastewater treatment plant can be reuse as an adsorbent for a certain cationic and anionic azo dyes from textile and or leather industry effluents. Because EC sludge expected to have iron oxide and hydroxide during the electrochemical processes of wastewater treatment, it can be used for adsorptions for azo dye removal. Produced EC sludge can have positively charged surface, specially ferric and or ferrous surface charge. Thus, EC sludge as an adsorbent will have adsorption potential to adsorb acidic (anionic) dyes in the principles of electrostatic attraction. To this study, the author intends to use direct red 28 (DR28) dyes as a modal azo dye from the textile and or leather industry. Basic batch adsorption parameters (effect of dye concentration, solution pH, reaction temperature, mixing time and adsorbent dosage), as well as adsorption isotherm, kinetics, and thermodynamics study on to raw and calcined EC sludge were investigated. DR28 dye on to calcined EC adsorbent has recorded as highly removal efficiency at pH of 2, initial dye concentration of 20mg/L, time of 60 min, adsorbent dosage 1g/100mL and temperature of 25±2℃, ambient temperature
