Abstract
\n\nThis study aims to analyze the heavy metal content in different parts of pumpkin (pulp, flesh, and seeds) and assess the associated health risks for consumers. Growing worries about food safety and the possible health effects of heavy metal contamination in agricultural goods are the driving forces behind this study. Thus, by using microwave plasma atomic emission spectrometry, the primary heavy metals (Cr, Mn, Fe, Ni, Cu, Zn, and Cd) in pumpkin samples were measured. Risk ratios (HRs) and total cancer risk (TCR) related to eating various pumpkin sections were used to evaluate non-carcinogenic dangers. The suggested daily intakes were computed and contrasted with predetermined safety limits. Microwave plasma atomic emission spectrometry was used to test metal concentrations, guaranteeing great accuracy and dependability. The study's findings demonstrate that the pumpkin's metal distribution is uneven. The pumpkin's flesh and seeds are incredibly high in iron and zinc, which can aid the local population with mineral shortages like anemia. However, the edible pulp's lead and chromium concentrations-4,679 mg/L and 4,437 mg/L, respectively far beyond the WHO's global safety standards. The objective risk ratio for lead is greater than 1.0, and the cumulative risk index for all metals combined also exceeds the safety threshold. This indicates that long-term daily consumption of these pumpkins poses a significant risk of chronic health problems, particularly neurological and kidney damage due to lead exposure. The strong correlation between toxic metals such as Pb, Ni, and Cd in the pulp suggests that the exterior of Sanbitu Kebele pumpkin is the most affected by environmental contamination, even though the pulp only contains iron and chromium. The presence of Pb (Lead) and Cr (Chromium) in the pumpkin—specifically at the alarming levels shows that the crop has reached a state of extreme toxicity that far exceeds international safety limits. Thus, removing the pulp before consumption is strongly recommended to reduce lead and nickel intake. Environmental monitoring of soil and water in the area is necessary to identify the source of contamination and ensure food security

\n\nThis study assessed the ’Effects of AF on CC Adaptation and Livelihood Resilience in Hawassa Zuria Woreda, Sidama Regional State, Ethiopia. The study employed multistage sampling to get 147 households from AF adopters and 114 households from non-adopters of AF totally 261 sample respondents were interviewed. Both primary and secondary sources of data sources were used. Primary data were obtained by interviewing 261 smallholder male and female household heads, FGDs and KIIs. Secondary data were obtained from published and unpublished materials. Descriptive and inferential statistics such as table, multiple linear regression, Chi-square test, independent t-test were used. Mann-Kendal trend analysis of climate data from Ethiopian Meteorology showed that, average maximum temperature of Hawassa Zuria Woreda for the past 30 years was increased by 0.043oC annually, whereas the average minimum temperature was increased by 0.0549°C. The CV of rainfall in the study area were 15.84%, 21.19%, and 29.63% for annual, Kiremt and Belg rainfall respectively, which indicate that there was high inter-annual variability of rainfall between 1991-2023. The results showed that adoption of AF improved maize productivity by 25.43 % than NAF households. The independent t-test showed that there was a statistically significant difference in the yield of Enset and Maize crop between AF and NAF households in the study area (p<0.05), implying AF is better than NAF to minimize the effects of CC related shocks. The comparative analysis of income level between AF and NAF households was 5,349.32±1871.51 and 2,567.64± 1138.12 Birr than agroforestry participants (). Birr, respectively. The independent t-test showed that there was a significant variation in the income between AF and NAF in the study area (p<0.05). This is related with high diversity in AF that tends to enhanced production year round, generated food for sale and consumption, minimize production cost of fertilizer. The ultimate importance of AF is reducing susceptibility and enhance resilience of farmers to the impacts of climate variability and change is through reducing erosion intensity, increasing crop yield and assets such as trees, livestock, and crop production. Therefore AF adopters had more assets and crop yield in their stock, less exposure and had advanced resilience to CC compared to the NAF adopters. The study recommended that Since agroforestry is one of the core pillars of CSA and enhances CC adaptation and mitigation, GOs and NGOs should give due attention, provide incentives promotion and create of awareness for the farm households about the importance of AF practices and AF incentive to initiate the farmers to adopt and practice agroforestry practices

\n\nThe purpose of this study was to assess the practices of developing and implementing schoollevel plans in secondary schools of Delo Mena Woreda, Bale zone, Ethiopia. A descriptive survey study was conducted in three purposively selected secondary schools in Delo Mena Woreda, Bale Zone, Ethiopia, utilizing questionnaires, interviews, and document reviews from a sample of 78 teachers and 37 administrators to assess the practices of developing and implementing secondary school-level plans. Key findings revealed significant deficiencies that impede effectiveness, including the lack of evidence-based assessment and selfassessment in identifying priority areas, inadequate stakeholder participation and coordination, weak monitoring and evaluation of plan implementation, and an insufficient performance reward system. The study concludes that these deficiencies are major factors impeding effective school-level planning and implementation. It was recommended that the Regional Education Bureau (REB), and schools coordinate efforts to address these problems proactively. This should include providing continuous training, technical support, and implementing rewards for high-performing stakeholders and school communities to ensure the successful implementation of school-level plans.

\n\nMalachite green, a widespread, persistent contaminant in trash and the environment that poses serious risks to aquatic life and human health, is utilized in the textile and dyeing industries. As a result, biosorbent made from plants is thought to be the most effective way to remove malachite green from aqueous solutions. It is built using plant matter or sustainable raw materials through a chemical activation method. Still, testing how well this natural filter pulls out malachite green mattered deeply for clean water and natures balance. The majority of academics are currently interested in removing malachite green from water because of its characteristics. One of the best techniques for influencing the availability, transformation, and bioavailability of malachite green is adsorption. The characterization findings demonstrated that the biosorbent had the largest macro porous surface area and a welldeveloped surface area for adsorption. Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X- ray diffraction (XRD) spectroscopy were used to examine the surface functional group, morphology, and crystallinity. The results of batch experiments showed that a number of factors, including pH, dose, contact time, temperature, and initial MG concentration, affect the adsorption of malachite green by a biosorbent produced from Datura stramonium roots. The ideal dose of 1g, pH of 8, starting malachite green concentration of 20 ppm, contact period of 30 minutes, and temperature of 30oC were noted. The Langmuir model with maximal adsorption capacity of 25.77 mg.g-1 had the best fit to the adsorption data (R2 = 0.996) according to the isothermal analysis, while the kinetic data supported the pseudo-second order model with an optimally suited R2 coefficient of 0.887 for malachite green. Lastly, the findings indicate that the removal of organic dye pollution from aqueous solution using a biosorbent generated from Datura Stramonium roots may be economically feasible. From the results, it is evident to expect that Datura Stramonium biosorbent will show comparable adsorption behaviors for the removal of various coloring agents from aqueous solutions, even if the experiment is limited to malachite green.

\n\nThe study was conducted to investigate the effect of ten weeks uphill running exercise on some physical fitness and physiological factors in case of long distance athletes of Ethiopian construction). The Ethiopian construction currently has 15 male and 15 female athletes training under it. The ten weeks uphill training was added to the training scheme as it was noted that uphill trainings are performed once in more than a month according to the information obtained from the coaches and the athletes. The 30 athletes were divided into two groups by gender. Pre intervention tests were performed for the selected variables (muscular endurance, speed endurance, VO2Max and muscular strength. Results of wall squat test for muscular endurance, 300m run test for speed endurance, coopers 12 minutes run test for VO2Max and the 1RM test for muscular strength were recorded before the intervention and after the intervention of the ten weeks uphill training. Descriptive analysis and paired samples t-test were performed to analyze the significance, magnitude and direction of the results before and after intervention. The results revealed significant negative mean difference and t values for muscular endurance, VO2Max and muscular strength indicating that significant direct relationship exists between these variables and uphill training as high values of the variables are related to improvement. Positive and significant mean difference and t-value is resulted for speed endurance showing inverse relationship. As lower results are indicants of improvement in this regard the case is interpreted as there exists positive and significant relationship between speed endurance and uphill training. Accordingly all the hypotheses targeted were accepted and hereby recommended to induce uphill training as appropriate with other regular training schemes.

\nstudy's findings, it was determined that students struggled greatly to improve their visual spatial
\nabilities in solid geometry. In order to effectively teach 3D shapes, the researcher advised
\nteachers to take the time to plan ahead, learn various applications that improve 3D shape
\nvisualization, and guide students in that direction. Teachers should also help students who are
\nlacking in general 3D shape skills.

\nThis study investigates the accessibility, utilization, and challenges of teaching aids in mathematics education across selected secondary schools in Addis Ababa, Ethiopia. Focusing on three schools within the Addis Ketema and Gullele sub-cities, the research employed a mixed-methods approach to gather quantitative data from 6 school principle, 58 teachers and 371 students through surveys totally the sample in this research is 435, this sample supplemented by qualitative insights from interviews and classroom observations.
\nFindings reveal that while visual and collaborative aids are the most commonly used, digital and audio aids are significantly underutilized due to systemic constraints. Major barriers include limited access to resources, inadequate teacher training, insufficient institutional support, large class sizes, and low student engagement. The study also highlights administrative inefficiencies as a predominant challenge, surpassing even financial limitations.
\nThe research concludes that enhancing the access of teaching aids requires targeted interventions, including improved teacher professional development, equitable resource allocation, and the establishment of mathematics clubs to promote hands-on learning. Recommendations are offered for educators, administrators, and policymakers to foster a more supportive environment for integrating teaching aids into mathematics instruction, thereby improving both conceptual understanding and student engagement in Ethiopian secondary schools.
