In this dissertation work the boundary layer flow of nanofluids past geometrical shapes such as wage, cylinder, disc, and cone embedded in porous media were studied. The physical problems of fluids flow are governed by highly nonlinear partial differen tial equations. Using suitable similarity transformations, the governing equations of flow were transformed into nonlinear higher order ordinary differential equations. Then, the computational solutions were obtained using recently developed numerical methods namely, Spectral quasilinearization method (SQLM) and Spectral relaxation method (SRM). The results of the study were compiled in the form of published pa pers on six different problems of incompressible fluid flow. In the study, nanopar ticles of Ag,CNTs,Al2O3,&Fe3O4 were also employed with water, ethylene glycol and Engine oil as the base fluids. Effects of embedded parameters such as magnetic f ield, viscous dissipation, nanoparticle volume fraction, Non-Newtonian fluid param eter, thermal radiation, pressure gradient, velocity and thermal slip effects, Cattaneo Christove heat flux Model, variable viscosity and thermal conductivity, and convec tive boundary condition on velocity, temperature and concentration distributions as well as skin friction coefficient, local heat and mass transfer rates were examined. The computational results were presented via embedded parameters with graphs and tables. The results revealed that the skin friction coefficient was improved while the local heat transfer rate was reduced with higher values of nanoparticle volume fraction, unsteadiness, viscous dissipation, Non-Newtonian Casson fluid, pressure gra dient, permeability, magnetic field, temperature and dependent viscosity parameters. Also, higher skin friction coefficient and lower local heat transfer rate were reported in the hybrid nanofluids than mono nanofluids. In addition, hybrid nanofluids show bet ter flow distributions with good stability of thermal properties than mono nanofluids. Thus, the obtained results are promising for the application of hybrid nanofluids in the nanotechnology sectors. Moreover, the accuracy of the solutions was checked against the previously published results and an excellent agreement were obtained. Finally, following the obtained results, conclusions and recommendations were indicated. Keywords: Boundary layer flow, Carbon nanotubes, Hybrid nanofluids, Porous media, Skin friction coefficient, Spectral collocation method.

A corelational design was employed in the study. A total of 186 respondents (177 teachers, 9 school leaders) were included into the study. The teachers’ respondents were selected by proportional and simple random sampling techniques while principals were selected by census sampling techniques. The data were collected through questionnaire, and interviews. Data gathered through questionnaire were analyzed using mean, standard deviation, Pearson r correlation and multiple regressions. Data obtained through interviews were qualitatively narrated and analyzed. The findings of the study revealed that school principals leadership practices were moderately practiced in government secondary schools of West Wollega Zone (M=2.7, SD=.77).The secondary schools have moderate overall school performances (M=2.81, SD=0.24), however, they have drawbacks in fulfilling classrooms and other buildings, facilities, pedagogical resources and implementing documents in line with the set standards (M=2.41, SD=1.01). School leaders, teachers, students and support staff were rarely working as a team, with (M=2.20, SD=1.04). Teachers were also rarely evaluate and give feedback on the curriculum (M=2.44, SD=1.09). Assessment of students’ performances were not as accurate as needed in government secondary schools of the zone (M=2.33, SD=1.06). Schools were also unable to forge strong partnership with parents and the local community (M=2.46, SD=1.14). The transformational leadership practices of the school principals have a positive significant correlation with the school performance (r=0.391, p=.000) and there is also positive correlation (r= 0.475, p=.000) between school performance and instructional leadership practices. Overall, the findings showed that there is a significant and positive correlation between school leadership practice and school performance (r = .452, P < 0.05). It was found that the leadership practices variables had an overall positive effect on explaining school performance (r2= 0.469). The result shows that about 47 % of the variation in school performance was explained by the two subscales of leadership practices combined. Based up on the findings, it was recommended that, zonal educational office and woreda educational office need to support, and train school leaders by in-service and other program to enhance the capacity of leaders with the concept of transformational & instructional leadership practices and develop schools performance. Similarly, zonal educational desk and woreda educational office also need to incorporate, amend and adopt the dimensions of transformational & instructional leadership practices in the criteria for performance evaluation system of school leaders.

Literatures were reviewed on the concepts of teacher’s instructional practice, the types of instructional practices teachers use in teaching chemistry, teachers’ pedagogical skills, monitoring or assessing the progress of learners and the relationship between teachers’ instructional practices and students’ academic achievement. In order to meet the objectives of the study quantitative and qualitative (mixed) research method was employed. Moreover, descriptive and correlation design were employed. Eight Secondary Schools were selected through simple random sampling technique to be the sample of the study. From these secondary schools 22 teachers and 364 students were selected through simple random sampling technique and eight secondary school principals and 10 vice principals were selected through available sampling technique to be the sample of the study. Data were collected through questionnaires, interviews and document analyses. Data obtained through questionnaires were analyzed using statistical tools like frequency, mean, standard deviation and Pearson’s correlation coefficiet and data gathered through interview and document analysis were considered to complement the questionnaires in narrative form. Then, major findings of the study were identified. Accordingly, Chemistry teachers implements interactive lecturing and questioning learning practices to the average level and rarely organize the students’ seat in to a circular or semi-circular shape prior to lecturing. In addition, they rarely implement team based learning practices and there are no permanent groups in chemistry classrooms. On the other hand, Chemistry teachers do not promote active student learning activities. They have drawn backs in teaching their students how to assess their learning, how to use technology in chemistry and motivate their students to take part in classroom activities. Students’ academic achievement in Chemistry was low. There is strong, significant and positive relationship between teachers’ instructional practice and students’ chemistry academic achievement. The current status of teachers’ instructional practices in secondary schools of West Wollega Zone was moderately implemented. The study revealed that Chemistry teachers in West Wollega Zone Secondary Schools have moderate level of pedagogical skills. The status of students’ academic achievement in chemistry in West Wollega Zone Secondary Schools was not to the extent needed, but there is strong, significant and positive relationship between teachers’ instructional practice and students’ chemistry academic achievement. On the basis of these conclusions the researcher recommended that Chemistry teachers are advised to implement team based learning strategy. In addition, teachers don’t have to depend on lecture approach and have to improve their instructional practices to improve the students’ academic achievement. Furthermore, Zone Education Office and Woreda Education Office have to arrange trainings to enhance or update teachers’ pedagogical skills. Key words: Instructional practices, students’ academic achievement.

Descriptive survey design was used to conduct the study with qualitative and quantitative methods. Furthermore, the correlation coefficient was used to uncover the associations among the variables considered. In this study, 150 sample teachers and 10principals from 10 secondary schools were participated using simple random and availability sampling techniques respectively. The main data collection tools used for this study were questionnaires and interview. The quantitative data was interred into SPSS version 20 and analysed using both descriptive and inferential statics; whereas qualitative data were used to support the main data through narration in words. Before the actual data collection, piloting of questionnaires was done in one secondary schools of West Wollega Zone. To establish the reliability of the instrument, the researcher used the test-retest where the second test administration was done one week after the first one. In addition, mean and standard deviation also used to carry out to see the extent of principal practice and implementation of SIP in secondary school of West wollega zone. The finding of the study was: the principal practice of instructional leadership in the secondary schools of west Wollega Zone was not as expected. The results of the study intended to favour the principals to improve their theoretical knowledge and skills of leadership through dealing with leadership practices that might enable more SIPS in their work place. Through improved SIP teaching-learning improved which favors students to improve their educational results. The principal’s leadership practice had negative impact on SIP since principals were not highly involved teachers, students and parents in designing school mission and vision. The school communities are not satisfied in the leadership practice. Consequently, they couldn’t provide and support for instruction. They do not support on managing students behavior. Different activities were done at the schools level to overcome the problem of school by teacher as a principal practice. The schools and their principals are strongly recommended: all principals should get more awareness concerning SIP and the effect it has on schools work. Thus, the principals should get different short and long training. Principals and others concerned administrators should work to create positive social climate between teachers and the community. It is better if the preparation policy of SIP get more consideration by the government on low principal practice. The community should give appropriate status for develop SIP to survive and work in the community. Key words: principal practice, SIP, West Wollega Zone

From quantitative approach correlational research design was employed. Using clustered, stratified proportional and availability sampling techniques, eight secondary schools (18 percent), 248 teachers (23 percent) were included. Two survey instruments (Multifactor Leadership questionnaire (MLQ) and one-self-made together with document analysis were used to collect data, which was entered into SPSS version 24. Both descriptive and inferential statistics were used to be analyzing data. The finding of the study showed that the most predominant leadership style is transformational leadership which is at moderate level (M= 2.88; SD =.74). From transformational leadership, idealized influence behavior is the highest (M= 2.99; SD = .68). Laissez- faire leadership was the least leadership style employed (M=2.15; SD =.90). The outcome of leadership was found to be moderate (M=2.96; SD=.77). The average teachers’ performance was found to at slightly high level (M=3.77; SD=1.00). The highest dimension from teachers’ performance was subject matter knowledge (M=3.95; SD=.93).Participation in co-curricular activity was the least dimension of teachers’ performance performed (M=3.48, SD=1.14). The relationship between principals’ leadership styles and teachers’ performance was found to be moderately positive, relation(r= .41**; p. 000). Further, after testing the underlying assumptions, stepwise linear regression was conducted to examine whether the score of teachers performance can be determined from the scores of leadership style. The result showed that transformational leadership is the most determinant, and determines 43 percent (F (3, 236) = 58.34; p = .00; R2=.43; B=2.04). Keeping other things constant, one unit increment in transformational leadership will raise teachers’ performance, at least, by half unit. To raise teachers’ performance and other outcomes, application of more transformational leadership is recommended. The zone educational office is advised to offer training on transformational leadership style to principals.

\n\nNewcastle disease (ND) is a highly contagious and economically devastating viral disease affecting poultry worldwide, including Ethiopia. This study aimed to molecularly detect Newcastle disease virus (NDV) responsible for outbreaks in commercial poultry farms in Nekemte town and selected districts of East Wallaga zone, Oromia region, Ethiopia. A cross sectional study was conducted from December 2024 to May 2025, focusing on farms reporting suspected ND outbreaks. A total of 20 pooled samples (4 pooled oropharyngeal swabs, 4 pooled cloacal swabs and 12 pooled tissue samples) were collected from clinically affected and freshly dead poultry. Real-time reverse transcriptase polymerase chain reaction (rRT-PCR) was employed to detect the NDV M gene. Results confirmed the presence of NDV in commercial poultry farms in Nekemte town and selected districts of East Wallaga zone, with an overall detection rate of 5%. The highest detection was observed in brain tissue samples (33.33%), suggesting viral tropism for neural tissues. The outbreak investigation revealed significant morbidity (15.18%), mortality (7.85%), and case fatality (51.72%) rates, underscoring NDV as a major cause of poultry losses in the areas. Affected poultry exhibited respiratory, gastrointestinal, and neurological symptoms, while postmortem examinations identified hemorrhagic ulcers and liver necrosis, consistent with velogenic NDV strains. Nekemte town (07) had the highest NDV detection rate (25%), while no positives were detected in other study sites, indicating localized outbreaks. The study confirms NDV as a significant threat to poultry farms in the study areas, highlighting the need for improved vaccination programs, biosecurity measures, and further research to characterize circulating strains.

\n\nBackground: Due to their fragile physiologic functions, over 65 percent of deaths from complicated severe acute malnutrition occur in the first week of treatment, primarily due to medical complications. To reduce this, early stabilization is crucial, and there is limited evidence regarding stabilization time in Ethiopia. Objective: To assess time to stabilization and its predictors among 6 to 59 months old children admitted with severe acute malnutrition to selected hospitals in Western Oromia from January 2020 to December 2024. Method: A retrospective cohort study was conducted from January 20 to february 29, 2025 on 543 sampled children selected by a simple random sampling from severely malnourished children admitted to three selected hospitals in Western Oromia between January 2020 and December 2024. After collecting data using kobotoolbox, it was exported to STATA version 17 for analysis. Kaplan Meier curve and log-rank test were used to estimate the stabilization rate and presence of statistically significant difference in survival and hazard rate between a categories of explanatory variables. Proportional hazard assumption was checked using schoenfeld residual test and log-log survival curve. After performing model comparison, Weibull model was selected and variable with p<0.25 on bi-variate regression was selected for multivariable weibull regression. Estimating adjusted hazard ratio with their respective 95% confidence interval, P-value of less than 0.05 was used to declare statistically significant association with stabilizing time. Result: Over 5600 child-days of observation, the median time to stabilize from severe acute malnutrition was 11 days, with 86.39% rate of stabilization and 86.6/1000 incidence of stabilization (95% CI: (74.45 - 89.44)). Immunization status (AHR: 0.66, 95 CI (0.54-0.8)), pneumonia (AHR: 2.17, 95 CI (1.74-2.70)), hospital acquired infections (AHR: 1.34 95CI (1.09-1.65)) and vitamin A supplementation (AHR: 0.61, 95CI (0.49-0.77)) were predictors of stabilization time. Conclusion: This study found prolonged time to stabilization of 11 days compared to recommendation of Ethiopian national management protocol of severe acute malnutrition. To achieve quicker stabilization, health professionals, hospital managers, and all stakeholders must collaboratively address and reduce the burdens stemming from identified predictors.

\n\nBackground: Breast self-examination serves as a critical, cost-effective strategy for early detection of breast cancer, the second most prevalent malignancy among women globally. In Ethiopia, where access to mammography is limited, breast self-examination remains a critical screening tool. This study addresses critical evidence gaps regarding Breast self-examination practices in western Ethiopia.
\n\nObjectives: To assess Breast self-examination practice and associated factors among women attending public health facilities in Nekemte town, western Ethiopia, in 2025.
\n\nMethods: A facility-based cross-sectional study was conducted from January to February 2025 across four public health facilities in Nekemte. Using systematic random sampling with proportional allocation Data were collected through pretested interviewer-administered questionnaires adapted from validated tools, 418 women attending maternal-child health services were enrolled (99.8% response rate). Analysis included bivariate logistic regression (p<0.25 entry threshold) and multivariable modeling with verification of assumptions: Hosmer-Lemeshow goodness-of-fit (p=0.658), variance inflation factors <10, and 86.1% classification accuracy.
\n\nResult: Breast self-examination practice prevalence was 26.3% (95% CI: 22.3 – 30.7), with only 20% (22/110) demonstrating good Breast self-examination practice. Significant predictors included: history of breast affliction (AOR=4.43; 95%CI: 1.27-15.45), high perceived susceptibility (AOR=10.20; 95%CI: 1.87-55.61), adequate knowledge (AOR=3.68; 95%CI: 1.09-12.38), and high barriers (AOR=0.25; 95%CI: 0.07-0.90).
\n\nConclusion: The findings reveal critically low Breast self-examination uptake in Nekemte, primarily constrained by knowledge gaps and perceptual barriers. Recommended interventions include: facility-based Breast self-examination training programs, community awareness movements, and integration of BSE education into routine health services. These evidence-based strategies could strengthen Ethiopia's national cancer control efforts in resource-limited settings..
