Advancing Research Through DataCite’s Global Access Fund: Mekelle University, Ethiopia
(2025) Yemane Seged Gebru; Tekleweyni Geday Welegebrial; Guesh Amiha Birhanu; Eyasu Yazew; Mohamad Mostafa
Mekelle University (MU), founded in 2000 and located in Tigray, Northern Ethiopia, is a research-intensive institution dedicated to advancing knowledge, economic growth, and social welfare both nationally and internationally. As a founding member of the Ethiopian Research Universities Forum in 2025, MU is committed to elevating the visibility and impact of Ethiopian research on the global stage. A significant part of this mission involves ensuring our research is visible, accessible, and impactful. However, a critical gap was identified: a vast repository of valuable scholarly outputs, including postgraduate theses, dissertations, and datasets, remained largely invisible to the global research community because they lacked persistent identifiers (PIDs) like Digital Object Identifiers (DOIs). This made them difficult to cite, track, and reuse, limiting their potential impact.
Multi-Model Mathematical Analysis of Cholera Transmission Dynamics: Stochastic Effects and HIV-Measles Co-infection Interactions
(Mekelle University, 2026-05-11) Hailu Tkue Welu
This dissertation develops an integrated suite of mathematical models to unravel the complex dynamics of cholera transmission and its dangerous synergies with immunosuppressive infections including HIV and measles, moving beyond traditional singledisease frameworks by unifying deterministic and stochastic bifurcation analysis with syndemic co-infection modeling. The research demonstrates that environmental noise reduces the effective reproduction number, making stochastic thresholds more stringent than deterministic ones, while integrated prevention-treatment strategies achieve ninety-four percent elimination probability compared to eighty-two percent for preventiononly approaches. Measles-induced immune depletion amplifies cholera transmission by two hundred twenty percent, with co-infected individuals experiencing seventy-five percent higher mortality risk despite comprising only sixteen percent of infections; similarly, HIV-cholera co-infection reveals a critical shedding ratio of one point five that triggers backward bifurcation, enabling cholera persistence even when the basic reproduction number falls below unity, with AIDS-stage shedding dominating transmission and explaining the failure of conventional control targets in high HIV-prevalence populations. Analysis of ecological competition between pathogenic and non-pathogenic Vibrio strains establishes that biomedical and environmental interventions are functionally interdependent, as backward bifurcation occurs when the competition coefficient exceeds a defined threshold, creating bistable regimes where disease persists below conventional elimination thresholds. Together, these findings advocate for integrated syndemic surveillance, synergy-adjusted elimination thresholds, and adaptive combined interventions, providing evidence-based recommendations for cholera control in resource-limited settings.
GIS AND RS BASED FLOOD HAZARD SUSCEPTIBILITY MAPPING USING AHP METHOD FOR THE LOWER AWASH RIVER BASIN (LOGIA-DUBTI AREA) AFAR, ETHIOPIA
(Mekelle University, 2026-05-07) ZAHARA FEREDE MOHAMMED
In recent time, floods are considered amongst the most catastrophic, frequent and widespread natural disasters worldwide causing severe economic and environmental damages as well as destruction of livelihoods. Flood mapping is an effective way to assess flood susceptible areas and determine factors that cause floods. This study aimed to define flood causative factors and develop flood hazard susceptibility map of the Lower Awash River Basin (Logia to Dubti), Afar region, Ethiopia using Geographic Information System (GIS) with the Analytical Hierarchy Process (AHP). The methods used in this study was the combination of: (a) field assessments of flood affected areas (using features of water-level markers), and (b) Geographic Information Systems (GIS) and Weight Linear Combination Technique (WLC). A total of six influencing factors were used for the AHP method, namely slope angle, soil types, land use/land cover, geology, elevation, and drainage density. All the parameters were overlaid in geospatial software. The AHP method is utilized in this study to find relative weight and produced pair wise comparison weighted criteria of the influencing factors. The findings of this study shows that slope is the most significant factor contributing to flooding because it was the highest weight criteria at 37 % while the least significant factor is drainage density at 4%. The consistency ratio (CR) value was 0.07 which is acceptable as this value is lesser than 0.1. Flood hazard susceptibility map of the study area was produced by applying pair wise comparison based on weighted criteria in Arc GIS environment by using the weighted overlay method. The final map was consists of 10 𝑘𝑚2 (4.15%) very high flood susceptibility, 94 𝑘𝑚2 (39%) high susceptibility, 114 𝑘𝑚2 (47.5%) moderate susceptibility and 23 𝑘𝑚2 (9.54%) low susceptibility. However, moderate areas can change into high susceptibility and very high susceptibility if no proper flood management is taken.The flood susceptibility map was further validated by using the ground truths data (GPS point) obtained from locations that had experienced flooding and the data were analyzed by using GIS software. These validation results demonstrated a strong agreement between the predicted flood prone area and actual flooded location, conforming the accuracy and reliability of developed flood hazard susceptibility map. The study findings are crucial for improving flood response measures as well as for implementing mitigation measure such as, forecast and warning system, and maintaining and updating structural flood protection measures. Therefore, the findings of this study can be used for further research and environmental management of flood hazards in the study site. .
PETROGRAPHIC AND GEOCHEMICAL CHARACTERIZATION OF THE ADMEYTI IRON OCCURRENCES, NORTHWESTERN TIGRAY, NORTHERN ETHIOPIA
(Mekelle University, 2026-04-21) KIROS GEBREHIWOT KIDANE
The study area is located about 15Km far close to the Sheraro town in the northwestern zone of Tigary close to the Ethiopia and Eretria boarder. The main aim of the study was to determine the petrographic and geochemical characteristics of the lateritic iron deposit used to constrain the genesis as well as the resource potential of the deposit. The geology of Ademeyti and its surrounding area is comprised in low grade metamorphic rocks and Phanerozoic -Mesozoic sedimentary rocks separated by angular unconformity. The exposures in the area are stratigraphically represented as; slate, meta-sandstone, lateritic sandstone and aphanatic basalt in composition. The integrated geological, mineralogical and geochemical study, the lateritic iron deposits have been formed from the insitu weathering of ferruginous sandstone layer forming irregularly distributed patches. The structural alignments suggest that the foliations and folds are linked with the N-S directional stress whereas shear indicators are resulted due to the E-W directional compression. Petrographic and XRD data suggested the development of hematite from goethite and goethite from limonite and limonite from the ferruginous meta sandstone deposit. Hematite is higher in proportion compare to goethite while opaque, quartz, kaolin and illitmica are accessory minerals. The geochemical signatures, ore paragenesis, and their interpretations suggest that the lateritic iron deposit were formed by intensive chemical weathering and alteration under the tropical climatic condition involving the removal of the mobile elements and residual accumulation of iron oxides/hydroxides along fracture surfaces, grain boundaries and through the vertical enrichment process involving the dissolution, removal and decomposition of silica and feldspars respectively. Six patches zones have been recognized with average content of 33.42 wt. % of iron and tonnage of 45.49 metric ton.
