Abstract Preview:
This research has been designed to explore some choreographic matters of selected Amharic Music, and it has employed stylistics approach in association with the musical functions or thematic purposes related to visual narrative inquiry.
The rationale behind the research project was related to the discussion of some choreographic maters of this study in relation to theme, creativity and deviation related to the videos of the selected music, for such practice has been less experienced in researches before. This is so, for people in most of the time perceive the choreographic matters or form related issues of music and the thematic function which could be transferred through the videos as independent concerns. However, form and content of a certain artistic production are the two sides of a coin which could not be investigated and understood independently; this is so, for, it is obvious that what is made on the form is all about the content of any artistic production and vice-versa. This was made in this study with the discussion of the concept, choreographic matters of some selected Amharic Music made on the presupposed themes advocated by the videos in relation to the range of creativity and deviation.
Therefore, the intention of the current study was to deal with the exploration of choreographic matters as reflected in the musical videos in relation to creativity and deviation made to convey thematic matters of the videos, for these two artistic concepts (creativity and deviation) are the inevitable techniques of music as one genre of fine art. The study has been concluded with the following demonstration.

The study has been concluded with the following demonstration.
On top of their own peculiarities, all the videos are similar in their disclosure of artistic creativities experienced both in content and form levels. This creativity extends the range of experiencing artistic deviations. At least all the selected videos commonly share the ideas in dealing with the videos potential of keeping traditional dance movements, the range of improvisations and expressiveness inculcated in line with modernizing the dances in the videos and the intentional and unintentional global influences and hybridizations.

Background: Cisplatin-based chemotherapy regimen associated nephrotoxicity is a significantadverse effect that restricts the standard dose of cisplatin by impairing renal function. There is alack of data on cisplatin-based chemotherapy-induced nephrotoxicity (CIN) in Ethiopian patientswith gynecological cancer. This study evaluated the factors associated with CIN and its impact onthe survival status of patients with gynecological cancer at Northwest Ethiopia oncology centers.Methods: This institutional-based retrospective cohort study included patients with gynecologicalcancer who received cisplatin-based chemotherapy between 2020 and 2021 at NorthwestEthiopia oncology centers. CIN was evaluated using the Common Terminology Criteria forAdverse Events (CTCAE) version 4 criteria and Kidney Disease Improving Global Outcomes(KDIGO) Guideline. A logistic regression model was used to identify the factors associated withCIN. The Cox proportional hazards regression model was used to determine the impact of CINonpatients survival. The cutoff point was a P value of < 0.05 for declaring statistical significance.Results: A total of 394 patients with gynecological cancer were included in the final analysis. Theincidence of CIN was 27.9 % (95 % CI 23.4,32.7). Old age (≥60 years) [adjusted odds ratio(AOR)=1.7,95 % confidence interval (CI) (1.1–2.9); P=0.039],low serum albumin (50 mg/m2) [AOR=2.6,95% CI (1.4–4.7), P=0.002]were significantly associated with CIN.CIN[(adjusted hazard ratio(AHR)=3.2,95 % CI (2.7–9.5), P=0.004]and cisplatin dose reduction [AHR=2.7,95 % CI(1.7–4.3) P=0.021] were significant factors of death among patients with gynecological cancer.Conclusion: More than a quarter of patients receiving cisplatin-based chemotherapy developedCIN, which negatively affected their survival. This study recommends that prescribers pay specialattention to patients with older age, lower serum albumin levels, and high-dose cisplatin toimprove renal function and survival. Cisplatin-based chemotherapy-induced nephrotoxicitysignificantly affects the survival of gynecological cancer patients.

This study aims and documents the clinical and laboratory diagnosis of bovine dermatophilosis, caused by Dermatophiluscongolensis that causes exudation and matting of hairs and wools with the formation of crusts and scab. An adult local breed bullwith a history of reduced appetite, pruritus, dirty scabs and crusts as initial lesion coalesce on its different body parts was presentedto Debre Markos multipurpose veterinary clinic. The rectal temperature and other vital parameters were within the normalrange. The clinical signs observed were exudative dermatitis forming crusts and scabs, pruritus, matted hair like a paintbrushand keratinized material creating wart-like lesions that were widely distributed in different body parts. Few ticks were observedon the skin of the bull suspected as vector of the disease. Culture of skin scraps on blood agar showed small, grayish-white raisedgranular and hemolytic colonies. Staining of skin scraps by Giemsa and Gram’s stain and cultured colony by Gram’s stain indicatedthe characteristics of Dermatophilus congolensis, etiology of dermatophilosis. Other laboratory tests also showed the characteristicsof D. congolensis. The case was treated by penstrep and ivermectin parentally and iodine tincture topically, and the bull showedprogressive clinical improvement and complete recovery within 2 months. In conclusion, dermatophilosis is an economicallyimportant skin disease, highly prevalent in Ethiopia, and needs early detection and treatment by penstrep intramuscularly andivermectine subcutaneously with iodine tincture topically in line with proper husbandry practices to control the losses.

IntroductionCancer is a leading cause of global morbidity and mortality, significantly impairing patients’quality of life (QoL). Integrated Palliative Care (IPC) has been proposed as a holisticapproach to enhance quality of life by addressing patients’ physical, emotional, and psy-chosocial needs. While some studies suggest Integrated Palliative Care improves qualityof life more than standard care, the evidence remains inconclusive. This systematic reviewand meta-analysis aim to evaluate the comparative impact of Integrated Palliative Careversus standard care on the quality of life in cancer patients.MethodsA comprehensive search of databases including PubMed, Cochrane Library, and Embase wasconducted. We selected randomized controlled trials (RCTs) comparing Integrated Palliative Careand standard care for cancer patients, focusing on the quality of life as measured by validatedtools such as the EORTC QLQ-C30 and FACT-G. Data were pooled using a random-effectsmodel to account for study heterogeneity. Subgroup and sensitivity analyses were also performed.ResultsNine randomized controlled trials involving 1,794 patients met the inclusion criteria.Meta-analysis showed that Integrated Palliative Care significantly improved quality oflife compared to standard care (SMD = 3.25; 95% CI: 1.20–5.30; p < 0.001). Studiesconducted in Asia showed the highest standardized mean difference (SMD = 6.15; 95%CI: 3.07–9.23; p < 0.001), followed closely by studies from Africa (SMD = 6.0; 95% CI:5.13–6.87; p < 0.001), compared to those from other regions. Similarly, research focusingon lung cancer patients showed the greatest standardized mean difference of (SMD =6.15; 95% CI: 3.07–9.23; p < 0.001) relative to other cancer types. Furthermore, studies
involving newly diagnosed cancer patients recorded the highest standardized mean differ-ence of (SMD = 5.69; 95% CI: 4.57–6.80; p < 0.001).ConclusionIntegrated Palliative Care significantly enhances the quality of life in cancer patients comparedto standard care. These findings support integrating Integrated Palliative Care into oncologypractices to provide comprehensive, patient-centered care that addresses both physical andemotional needs. Further research should explore long-term benefits across diverse populations.

This study investigates the performance of hemispherical solar stills (HSS) enhanced with date kernelsand olive kernels as heat storage materials to improve water distillation efficiency. By utilizing thesenatural and sustainable materials, the research highlights an alternative to synthetic options. Rigorousexperimentation and detailed analysis under identical conditions reveal that both kernels significantlyimprove heat retention and water production rates. The HSS with date kernels (HSSDK) achieved adaily water productivity of 6.66 kg/m2 day, representing an efficiency increase of 10.87%, while theHSS with olive kernels (HSSOK) produced 8.00 kg/m2 day, enhancing efficiency by 13.54%. The cost perm3 of distilled water for HSSDK is approximately USD 4.65, while HSSOK costs USD 3.89, comparedto USD 7.83 for the conventional CHSS system. These results demonstrate that the inclusion of heatstorage materials has significantly reduced the cost of water production, with reductions of about 40%for HSSDK and 50% for HSSOK compared to the conventional system. These results are attributedto the high thermal conductivity and specific heat capacities of the kernels, enabling effective heatstorage and gradual release. This study demonstrates the potential of agricultural by-products ascost-effective and sustainable solutions for solar water distillation. Further research is recommendedto optimize the quantities and configurations of these materials, as well as to explore their integrationwith other renewable energy systems to enhance overall efficiency and sustainability.Keywords: Hemispherical solar still, Date kernels, Olive kernels, Heat storage materials, Distillation efficiency

ABSTRACT While it is dependent on erratic rainfall and subject to drought and low productivity, agriculture is still the dominant economic activity in Ethiopia. Climate-Smart Agriculture (CSA) technology adoption enhances productivity, resilience, and climate mitigation, yet its adoption by smallholder farmers in Ethiopia’s West Gojjam Zone remains limited despite government promotion. However, research on the factors behind the determinants of the low adoption rate is limited in the study area. The main objectives of this study were to investigate the factors influencing the adoption of five CSA-aligned practices: crop diversification, livestock diversification, irrigation, agroforestry, and the application of chemical fertilizers across selected woredas. Data were generated using structured questionnaires, key informant interviews, and focus groups from a total of 236 households selected using a multistage sampling technique. The analysis made by a multivariate probit model revealed that significant determinants included the gender of the household head, education, farm size, income, irrigation access, credit availability, extension services, and farming experience. Findings suggest that enhancing crop and livestock diversification requires expanding irrigation access, strengthening extension services, and integrating climate-smart advisory programs to equip farmers with essential skills and resources. Additionally, improving credit access, providing climate information through mobile phone SMS for free, and promoting farmer training can boost irrigation adoption, while targeted awareness campaigns can encourage experienced farmers to adopt modern irrigation technologies.

Full Abstract:
ABSTRACT While it is dependent on erratic rainfall and subject to drought and low productivity, agriculture is still the dominant economic activity in Ethiopia. Climate-Smart Agriculture (CSA) technology adoption enhances productivity, resilience, and climate mitigation, yet its adoption by smallholder farmers in Ethiopia’s West Gojjam Zone remains limited despite government promotion. However, research on the factors behind the determinants of the low adoption rate is limited in the study area. The main objectives of this study were to investigate the factors influencing the adoption of five CSA-aligned practices: crop diversification, livestock diversification, irrigation, agroforestry, and the application of chemical fertilizers across selected woredas. Data were generated using structured questionnaires, key informant interviews, and focus groups from a total of 236 households selected using a multistage sampling technique. The analysis made by a multivariate probit model revealed that significant determinants included the gender of the household head, education, farm size, income, irrigation access, credit availability, extension services, and farming experience. Findings suggest that enhancing crop and livestock diversification requires expanding irrigation access, strengthening extension services, and integrating climate-smart advisory programs to equip farmers with essential skills and resources. Additionally, improving credit access, providing climate information through mobile phone SMS for free, and promoting farmer training can boost irrigation adoption, while targeted awareness campaigns can encourage experienced farmers to adopt modern irrigation technologies.

Abstract Preview:
Investing in agricultural water management by improving irrigation schemes helps to establish climate-resilientand sustainable agri-food systems, thus contributing to sustainable poverty reduction. The purpose of this studywas to identify the determinants of farmers’ willingness to pay (WTP) for irrigation water improvements inNorthcentral Ethiopia. Primary data collected from a random sample of 132 households were analyzed using thedouble-bounded contingent valuation method and binary logit regression model to identify what determinesfarmers’ WTP for irrigation improvement. The findings show that farmers’ mean WTP for irrigation water im-provements is 141.60 Birr/ha/year (2.50 USD/ha/year). The results of bivariate Probit model revealed that croptype, education, relative location to the irrigation scheme, irrigated plot size, and perceived drought risk sta-tistically and positively determine farmers’ WTP for irrigation water improvement. These findings offer valuablepolicy implications on how best to guide practical agricaltural water management. Policy interventions aimed atenhancing farmers’ behavior, awareness, and perception of drought-related issues, while also promoting cashcrop production, are likely to drive more farmers towards a positive WTP for irrigation water improvement.
