Effect of Perceived Social Support on Neonatal Birth weight Among Mothers Who Delivered In Jimma Medical Center, Southwest Ethiopia.
No full textBackground: Perceived social support provides a broad range of Emotional, Informational,
Instrumental, and companionship support. Some evidences showed perceived social support
curtails to enhance good perinatal outcome. However, its effect on birth weight has not been
studied in study area. Therefore, this study aimed to assess the effect of perceived social support
on neonatal birthweight among postnatal mothers in Jimma Medical Center.
Objective: To assess the effect of perceived social support on neonatal birthweight among
mothers who delivered in Jimma Medical Center, Jimma, southwest Ethiopia, 2024.
Methods and materials: A facility-based retrospective cohort design was employed in the
maternity ward of Jimma Medical Center, from March 10 to May 02, 2024. A total of 403 mothers
were selected by using systematic sampling technique. The data were collected face to face by
using semi-structured questionnaire. Then entered into epi info version 7.2 and exported to SPSS
version 26 for data analysis was used to compare perceived social support and birth weight.
Linear regression analysis was used to investigate the association between variables and at a P
value of 0.05 along 95% CI was declared statistically significant.
Results: The study revealed higher mean birth weights among infants of mothers with greater
social support (3120g high vs 2710g for low support, p<0.001). Each unit increase in
Multidimensional Scale of Perceived Social Support score was associated with 67.3g increase in
birth weight (β=67.3, 95% CI: 37.5-116.7). Additionally, positive predictors like being married
(β=23.2 ,95% CI :13.3-45.7), college or above education (β=14.8, 95%CI: 6.7-432.3), higher
monthly income (β=31.3 ,95% CI: 10.6-73.5), planned pregnancy (β=45.2 ,95% CI: 24.7-81.6),
and negative predictors drug usage during pregnancy (β=-23.9 ,95% CI: -39.4,-13.5), and
primiparity (β=-4.2 ,95% CI: -8.2,-2.9) were identified.
Conclusion: This study provides that maternal social support significantly influences birth weight
outcomes in Ethiopia. The findings highlight that enhancing social support systems could help
reduce the high prevalence of low-birth-weight infants in this population which requires focus of
health workers and institution. Therefore, healthcare systems should integrate social support
assessments into routine antenatal care and develop targeted interventions to strengthen support
network for pregnant women
Exploring Elf Teachers' Strategies of Error Correction on Students' Paragraph Writing Tasks: In Case Of Isera Woreda Secondary Schools Grade 11 Students
No full textThe purpose of this study was to explore teachers' strategies of error correction on students'
paragraph writing tasks at Isera woreda selected secondary schools. For the study, required data
were collected through interviews, questionnaire and observation. The participants of the study
were four secondary school grade 11 English languages teachers and 180 students of the study
areas. Participants were randomly selected. The research had descriptive design. With respect to
data analysis; both qualitative and quantitative methods were applied. The findings of students’
questionnaire can be forwarded that teachers were not use Meta linguistic codes whenever giving
error correction. More importantly, students responded that some of the teachers never give
comments properly and simply give marks without showing or indicating the erroneous parts.
Therefore, based on the result of the study; it is recommended that teachers should involve students
in the process of correcting errors as much as possible. In addition teachers should use clues or
any clear ways in giving correction and create a common understanding on the codes they use

No full textCoffee is the major source of foreign currency for Ethiopia and contributes more than 35%of the
total export earnings. This study was conducted in Manna district, Jimma zone of southwest
Ethiopia to assess factors affecting coffee (Coffea arabica) quality from September to November
2024. Multistage sampling technique was employed to select the population for the study which
involved both purposive and random sampling techniques. Data were collected through a
structured questionnaire administered to sample farmers, interviews, and observation. Both
descriptive and inferential statistics were used to analyze the gathered and cleaned data. For the
field survey, 92 household farmers were randomly selected following sample size determination
procedures of probability proportional to size technique and 16 coffee traders were purposively
selected from the four kebeles namely Kela Guda, Haro, Gube Bosoka, and Dawa. The data
were collected and analysed by using frequency and percentage. The study identified different
factors that hinder coffee quality in the area. Among these factors, management factors such as:
old age coffee trees, absence of pruning, improper use of weed control system, Socio-economic
factors such as shortage of cash, theft, poor share arrangement, institutional factors such as lack
of follow-up and support from the concerned body and climatic factors such as: heavy rain
during harvest and sunny weather condition that result in drying coffee tree were identified as
hindrance to coffee quality in the area under investigation. Therefore, the concerned body
should give continuous support and follow-up systems to the coffee farmers during the pre
harvesting, harvesting and post-harvesting period to prevent factors to coffee quality in the stud
Effective Elimination of Pollutants from Wastewater through a Combination Aerated-Photo-Electrocoagulation Technique: Investigation on Operational Parameters
Full text linkElectrocoagulation (EleC) can be combined with other processes to improve water and wastewater pollutant removal. EleC exhibits
enhanced performance when combined with advanced oxidation processes (AOPs). The reduction of color and COD in LLW was
examined using an aerated, photo (UV), aerated+UV, EleC, aerated+EleC, UV+EleC, and aerated+UV+EleC methods.
Experimental results showed that at the following parameters: treatment duration (TD) = 75 min, pH = 7, aerated flow rate (AFR)
=60lmin−1, UV power = 32 W, current density (J) = 0.50 A dm−2, COD = 2500 mg l−1, and electrode pair (EleP) = Fe/Fe, the
aerated+UV+EleC method eliminated nearly 100% of color and 95.50% of COD from LLW with an electrical energy
consumption of 7.70 kWh m−3. Compared to results from aerated, UV, aerated/UV, EleC, aerated/EC, and UV/EleC procedures,
the values discovered were substantially higher. In order to ascertain the most favorable circumstances for operation, the impact of
a number of different control factors, including TD: 15–90 min, AFR: 10–60 l min−1, UV power: 8–32 W, J: 0.1–0.60 A dm−2,
CODs: 1250–6250 mg l−1, pH: 1–11, GBE: 1–5 cm, and EleP: Al/Al, Al/Fe, Fe/Al, Fe/Fe on color and COD reduction was
investigated. The results demonstrated that LLW was effectively treated using aerated+UV+EleC treatment combination.

Triple-junction tandem solar cells: structural and spectral optimization for improved current matching and efficiency
Full text linkIn this work, a triple-junction tandem solar cell (TSC) has been designed in order to increase the photovoltaic (PV) perfor
mance through utilizing maximum light photons. To create three junctions in this work three subcells have been designed
and optimized at its best PV performance. The optimization of all the three subcells have been done through the various
variations in the absorber layer like thickness and bulk defect density (BDD). It has been seen that best PV parameters in
the top middle and bottom cell are maximum at high thickness and low BDD. For the designing of triple junction tandem
configuration, two filtered spectrums (FS1 and FS2) have been calculated for the proper current matching in the three sub
cells. The optimized triple-junction TSC demonstrates significantly enhanced PV parameters, including high open-circuit
voltage (VOC- 2.750), short-circuit current density (JSC- 16.45 mA/cm2), fill factor (FF- 83.40%), and power conversion
efficiency (PCE- 37.74%). The strategy of using filtered spectrums and exact design optimization provides a potential road
to the next generation of high-efficiency tandem solar cells, furthering the field of renewable energy solutions

Sulphur doped graphitic carbon nitride composite with Zinc oxide for electrochemical determination of Hydrazine
No full textHydrazine is highly toxic and widely used in chemical industry which causes
environmental pollution and even has negative impact to human health. The main
objective of the study was to synthesize S-g-C3N4/ZnO for electrochemical detection of
hydrazine. Developing of novel environmentally friendly, cost effective and efficient
material for electrochemical detection of hydrazine of great interest. The S-g-C3N4/ZnO
was prepared via sol gel- polymerization method. The synthesized material was
characterized by techniques such as XRD is primarily used to determine the crystal
structure of materials, FTIR is a widely used analytical technique that provides valuable
information about the chemical composition of materials and SEM is used to analyze
and compare the morphology and structural features analysis were evaluated. The
proposed composite material combines the unique properties of S- g-C3N4 and ZnO to
enhance the electrochemical performance for hydrazine detection. ZnO, known for its
excellent electrochemical properties and stability, further enhances the detection
sensitivity of the composite. The electrochemical performance of the modified electrodes
(S-g-C3N4/GCE, ZnO/GCE, and S-g-C3N4/ZnO/GCE) was evaluated for HZ detection,
comparing it to a bare GCE. Optimization of electrochemical parameters was performed
to enhance sensitivity. Results demonstrate that the S-g-C3N4/ZnO nanocomposite
significantly improved the electrochemical detection of HZ, exhibiting enhanced
sensitivity and selectivity compared to individual S-g-C3N4, ZnO, or the bare GCE. This
improvement is attributed to the synergistic effect of sulfur doping and the composite
formation, which increased the surface area, facilitated electron transfer, and provided
more active sites, using linear-sweep voltammetry (LSV) and showed a relatively low
detection limit 0.083 µM (3σ/m) with a linear range of 0.270 µM to 200 µM and good
sensitivity. Overall, S-g-C3N4/ZnO is a suitable material for the metal-free and low-cost
detection of HZ and may be a robust sensing platform with great potential for other
sensor developments
