This study was aimed to formulate formal and non-formal Geez language revitalization strategies by specifically exploring indigenous teaching strategies, analyzing pedagogical interfaces and needs, and assessing practical off-class revitalization strategies. Exploratory Mixed methods design was utilized an experiential qualitative design complemented by descriptive assessment to explore participants' lived experiences and perceptions. The research participants were traditional church teachers teaching Geʽez integrating with religious contents in Reading, Qene, and Literature schools under Ethiopian Orthodox Tewahedo Church (EOTC) education system. Qualitative data were gathered through in-depth interview and video-supported observations, which were analyzed thematically. The study made use of Geez language professionals and practitioners from Bahir Dar and Debre Markos Universities to prioritize relevant non-formal revitalization strategies. Findings revealed that indigenous teaching uses some teacher-centered and more student-centered indigenous methods that converge and diverge with traditional and innovative pedagogies of designing, implementing and assessing Geez language. Irrespective of the delayed learning of comprehension and minimal use of functional communication, the indigenous methods church teachers used were generally more practical and effective, especially in areas such as Qene and literature schools resulting in quicker and accurate mastery of the language. The analysis of linguistic necessities and wants revealed that all skills with the emphasis of vocabulary, grammar, reading and speaking were prioritized. Integration into church schools, media, cultural events, and language nests wre selected as significant language revitalization strategies selected for both inside and outside of school settings. The study concluded that the productive indigenous methods of teaching Geʽez could complement modern language teaching pedagogies, addressing gaps in both approaches. It recommended that language professionals learn from indigenous practices and suggested that Geʽez teachers adapt these practices with modern pedagogical principles. Lastly, language program designers and educators were encouraged to reconsider effective pedagogical interfaces to address challenges in all aspects language teaching: design, implementation and assessment.

Property valuation is a critical process in estimating the fair market value of a property during a transaction and title transfer, which has significant implications for tax collection, infrastructure development, and economic growth of one’s country. However, due to the absence of standardized valuation frameworks, Ethiopia’s valuation system is inconsistent between the government estimations and actual market values. It is also a reliance on the arbitrary estimation of brokers and influenced by deliberate agreements between sellers and buyers to undervalue real properties. These factors contribute the loss of potential government revenue in real property transaction. Thus, this study assesses the challenges and future prospects of real property valuation for title transferring during transactions in the Amhara Region, Ethiopia. The study focuses on inconsistencies in real property valuation practices, its implication for tax revenue, and the role and influence of brokers in the actual real property market. This study employs a mixed research approach by combining surveys, interviews, and document reviews to investigate the discrepancies between the government estimated value, the actual market value at which the property was transacted, and the agreed-up transaction price reported by both the seller and buyer. The findings of this study reveal significant gaps in the Ethiopia’s real property valuation system, including reliance on non-standardized valuation frameworks, outdated construction material prices, an irregular update to land grading and pricing, and the dominance of broker-led valuation characterized by arbitrary estimations, contributes to inaccurate valuation of real property leading to tax evasion and government revenue loss. The study reveals and analyzes how these practices cause revenue loss to the government, with documented cases showing significant differences between property value in the actual market and the value agreed upon by two parties (buyer and seller) used for tax assessment. Moreover, it identifies procedural inefficiencies, such as the absence of standardized valuation systems, reliance on nonprofessional brokers, and weak enforcement mechanisms, all of which aggravate inequities in real property valuation, transaction, and revenue collection. In order to address these issues, the study recommends adopting and implementing international valuation standards, regular updates to construction material prices, land grading and pricing systems, and the implementation of strict regulatory frameworks for brokerage practices. Through the integration of Ethiopia’s valuation system with global best practices, this research aims to ensure reasonable taxation and improve revenue collection for fostering sustainable economic growth in the region. The findings contribute to the border discussions on land administration reform in developing economies, emphasizing the need for institutional capacity building and legal framework development.Keywords: Real property, Valuation, Title Transfer, Broker, Amhara region

The world population has increased significantly in urban areas since 1990. Ethiopia, the secondmost populous country in Africa, has experienced rapid urbanization, exerting immense pressure on land allocation in its emerging cities. To address housing demand, the Ethiopian government has prioritized cooperative housing allotments in regional cities; however, the sustainability of this approach remains understudied. This research examines three key objectives: (1) the environmental, social, and economic sustainability of cooperative housing development; (2) urban-rural connectivity challenges and their implications for peri-urban sustainability; and (3) the integration of sustainability considerations in property valuation practices. The study focuses on six emerging cities in West Gojam, East Gojam, North Gojam, and Awi zones (Debremarkos, Bure, Bahir Dar, Injibara, Mota, and Finote Selam), incorporating survey data from 357 households, supplemented by key informant interviews and focus group discussions with planners, property valuers, and municipal officials. Data were analyzed using the Relative Importance Index (RII) and exploratory factor analysis, combining quantitative and qualitative approaches.First, the analysis of urban-rural linkages highlights governance and infrastructure deficits in peri-urban areas, such as poor road quality, inadequate public transport, and fragmented land management. These challenges hinder sustainable integration, necessitating coordinated planning, standardized land-use regulations, and investments in connectivity. Second, the study examines property valuation in city municipalities, revealing inconsistencies in procedures, outdated regulatory frameworks, and a lack of technological adoption (e.g., GIS, blockchain). Recommendations include digitizing valuation processes, aligning practices with market dynamics, and integrating sustainability criteria into regulatory standards. Third, the research assesses cooperative housing, identifying procedural inefficiencies, financial barriers, and informal practices like land flipping as threats to sustainability. Policy reforms, improved governance, and affordable financing mechanisms are proposed to enhance transparency and align cooperative housing with urban planning goals. Collectively, the findings underscore the need for holistic governance reforms, infrastructure investment, and stakeholder collaboration to foster equitable and sustainable urban development in Ethiopia. The study provides actionable insights for policymakers to address these interconnected challenges and advance national development objectives.Keywords: Allotment, Cooperative housing, Ethiopia, land development, Sustainability 

ABSTRACTSilver nanoparticles (AgNPs) were synthesized from the root extract Stephania abyssinica by aneco-friendly and cost-effective method. Stephania abyssinica root extract with AgNO3 solutionwas used to synthesize AgNPs. The synthesized nanoparticles were characterized by UV–Vis,FTIR and XRD spectrophotometers. The antimicrobial activity of the nanoparticles was testedby the agar disc diffusion method. The result was that the dark yellow colour solution changedto brown solution with AgNO3 solution confirming the formation of AgNPs. The UV–Vis peak at275 nm in the plant extract shows the presence of organic compounds that interact with silverto form AgNPs. The FTIR spectrum of AgNPs shows peaks at 3406 cm−1, 2353 cm−1, 1615 cm−1and 1021 cm−1. The XRD result showed that the AgNPs are face centred cubic crystallinestructures having a size of 20.8 nm. The synthesized AgNps are more potent in Gram-negative bacteria than Gram-positive bacteria.

Bread wheat (Triticum aestivum L.) is vital for over a third of the global population but facessignificant production challenges due to limited adaptable varieties, poor management practices,and environmental factors. New wheat varieties often fail in unfamiliar environments, leading tocrop loss. To address this issue, a study was conducted to evaluate the adaptability, performance,and yield stability of recently released high-performing wheat varieties over two years (2020/2021 and 2021/2022) in four districts of the East Gujjar Zone: Machakel, Debre Elias, Gozamin,and Baso-Liben. The trials were set up using a randomized complete block design (RCBD) withthree replications, and data were collected on the main traits such as days to heading, maturity,plant height, tiller number, spike length, spikelet’s per spike, biomass, and grain yield. AMMI andGEE biplot analysis were used to study genotype by environmental interaction. The combinedanalysis of variance for grain yield showed highly significant effects (P < 0.001) due to genotype(4.98 %), environment (66.83 %), and genotype × environment interaction (31.96 %). Grainyield varied across the environments, ranging from 3.72 t ha 1in Baso-Liben to 3.11 t ha 1 inMachakel. Among the genotypes, Ogolcho had the highest mean yield (4.55 t ha 1), whereasWane had the lowest (2.70 t ha 1). Genotype-by-environment interaction biplot analysis groupedthe eight test environments and six genotypes into two mega-environments and three genotypegroups. Wane, Lemu, and Ogolcho were the stable genotypes. This analysis identified the mostfavorable districts for wheat production and highlighted Ogolcho as the most productive wheatvariety in the study area. The results suggest that farmers in these districts should adopt Ogolchoto enhance wheat yield and increase their income.

While Model Predictive Control (MPC) has been widely studied in power electronics, its real-time imple-mentation on DC-DC boost converters—particularly under variable loading conditions—remains limited. Thispaper proposes a new real-time implementation of the Model Predictive Control (MPC) law for a DC-DC boostconverter connected to variable loads. This implementation ensures precise current regulation through accurateduty cycle control updates, enabling the inverter’s frequency switching to be activated or deactivated as needed.This is achieved by proposing a predictive model of the current occurring in the first channel of the convertermodel, where a fitness function—comprising reference tracking and control effort—is minimized. Compared tothe proportional-integral (PI) controller, the MPC law proves more efficient, particularly in preventing oscilla-tions in both transient and steady-state output current responses. This advantage is validated through experi-mental tests for either a current inductance load or a resistive load. Since this type of real-time implementationhas not been previously applied on this converter, it constitutes the main contribution of this paper.

Chickpea is a self-pollinated, diploid, and annual plant (2x = 2n = 16). After peas and beans, it is the most important legumein the world. Reduced chickpea production and productivity have been significantly influenced by the lack of improvedand adaptable genotypes, poor management practices, biotic factors such as disease and pests, and abiotic factors includingfluctuating rainfall and temperature. New chickpea genotypes introduced in Northern Ethiopia lack adaptability, stability,and performance evaluation, resulting in crop losses for farmers due to their susceptibility to the new and variable environment. To address these challenges, recently released high-yielding genotypes, alongside a standard check, were evaluatedfor adaptability, performance, and yield stability over 2 years (2022/2023 and 2023/2024) in three districts (Shebel, Awabel,and, Jabitenan) of Northern Ethiopia across six multienvironment field trials each employing a randomized complete blockdesign with three replications. SAS 9.4 and R software were used, showing significant differences in crop phenological stages,growth, and yield parameters across years and locations for test traits. Genotype, location, and year interactions significantlyinfluenced all Kabuli chickpea genotypes. The highest combined mean grain yield was obtained from genotype “Arerti”(2.42 t ha-1) followed by “Yelbie” (2.18 t ha-1), which explained their best performance among the tested genotypes. Analysis ofvariance revealed significant interactions and differences between genotypes and environments, with 15.6% of the variationin grain yield attributed to environmental factors, 6.4% to genotype differences, and 11.4% to genotype-by-environment interactions. The Genotype and Genotype × Environment biplot and Additive Main Effect and Multiplicative Interaction analysisidentified stable genotypes, representative environments, and interesting genotype–environment interactions. GenotypesArerti, Chefe, and Yelbie were identified as stable based on Genotype and Genotype × Environment biplot and Additive MainEffect and Multiplicative Interaction analysis. Environments Shebel and Jabitenan were identified as representative amongall environments considered. 

Background: Staphylococcus aureus is a major pathogenic bacterium associated with high morbidity and mortality worldwide. It exhibits resistance to multiple antibiotics, complicating treatment options. Despite its clinical significance, there is limited data on the prevalence of S. aureus infections and the patterns of methicillin and inducible clindamycin resistance, particularly in Ethiopia. Understanding these resistance trends is essential for guiding appropriate therapy and improving patient outcomes.
Objective: To assess the prevalence of S. aureus, methicillin and inducible clindamycin resistance patterns, and associated factors among patients with suspected bacterial infection at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia.
Method: A hospital-based cross-sectional study was conducted among patients suspected of bacterial infections from 10 June 2023 to 28 February 2024. Blood, wound swab, cerebrospinal fluid, urine, eye swab, synovial fluid, ear swab, and pleural fluid were collected aseptically and inoculated onto appropriate media. S. aureus was identified based on colony morphology, Gram staining, DNase test and biochemical tests. Antimicrobial susceptibility testing was performed on the isolates using the disk diffusion and the D-test techniques based on CLSI guideline. Data were entered into SPSS version 26 for analysis. Logistic regression was applied to assess the relationship between predictors and the outcome variable. A P-value of ≤ 0.05 with a 95% CI was considered statistically significant.
Results: Among the 339 study participants, 38 (11.2%) (95% CI: 8-15) tested positive for S. aureus. Of these isolates, 14/38 (36.9%) were resistant to methicillin, 5/38 (13.1%) isolates were resistance to clindamycin by routine disk diffusion test whereas 10/38 (26.3%) isolates exhibited inducible clindamycin resistance using the D-test. The level of multidrug resistance was noted in 10/38 (26.3%) of the isolates. Significant factors associated with S. aureus infection included illiteracy (AOR = 13.51; 95% CI: 3.56-21.90; P = 0.018), having larger family size (AOR = 12.14; 95% CI: 2.38-20.43; P = 0.024), and income level of less than 3,000 ETB (AOR = 6.20; 95% CI: 1.03-30.09; P = 0.046).
Conclusion: The study revealed an 11.2% occurrence of S. aureus among the study participants, with a substantial proportion exhibiting methicillin resistance (36.9%) and inducible clindamycin resistance (26.3%). These findings highlight a higher burden of clindamycin resistance in MRSA, underscoring the need for routine D-test screening to guide appropriate antibiotic therapy. Additionally, factors such illiteracy, low income and residing in rural areas were associated with S. aureus infection. Targeted health education initiatives should be implemented, especially in rural areas and among populations with low literacy levels, to improve hygiene practices and reduce transmission.

Eucalyptus was frst introduced to Ethiopia in the late 19th century to address the scarcity of frewood and construction wood in thecapital city. Since then, it has spread across the country and has become an important source of income for many households whilealso reducing the need for deforestation. Despite concerns raised by environmentalists about its eco-hydrological impact, theplantation has expanded to cover a vast area of the nation, including farmlands and mountainous regions. Currently, around506,000 hectares of land in Ethiopia are covered by Eucalyptus plantations. Te growth of Eucalyptus plantations can be attributed tovarious socioeconomic, ecological, and biological factors, including the increasing demand for wood and wood products. However,this growth has also led to negative environmental consequences such as reduced surface and groundwater fow, decreased cropproductivity, soil fertility degradation and depletion, and high water consumption, which can result in water scarcity. To address theseenvironmental impacts, it is essential to select appropriate species and sites and implement proper silvicultural and land use planningbefore planting. Additionally, promoting renewable energy sources and planting environmentally sound fast-growing indigenousand exotic tree species can help reduce the adverse efects of Eucalyptus on the environment.Keywords: deforestation; environmental impacts; Eucalyptus plantation; indigenous and exotic tree species
